Sex-related differences in serum biomarker levels predict the activity and efficacy of immune checkpoint inhibitors in advanced melanoma and non-small cell lung cancer patients. J Transl Med 2024; 22:242. [PMID: 38443899 PMCID: PMC10916307 DOI: 10.1186/s12967-024-04920-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Accepted: 01/20/2024] [Indexed: 03/07/2024] Open
Abstract
BACKGROUND Immune Checkpoint Inhibitors (ICIs) lead to durable response and a significant increase in long-term survival in patients with advanced malignant melanoma (MM) and Non-Small Cell Lung Cancer (NSCLC). The identification of serum cytokines that can predict their activity and efficacy, and their sex interaction, could improve treatment personalization. METHODS In this prospective study, we enrolled immunotherapy-naïve patients affected by advanced MM and NSCLC treated with ICIs. The primary endpoint was to dissect the potential sex correlations between serum cytokines (IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, GM-CSF, MCP-1, TNF-ɑ, IP-10, VEGF, sPD-L1) and the objective response rate (ORR). Secondly, we analyzed biomarker changes during treatment related to ORR, disease control rate (DCR), progression free survival (PFS) and overall survival (OS). Blood samples, collected at baseline and during treatment until disease progression (PD) or up to 2 years, were analyzed using Luminex xMAP or ELLA technologies. RESULTS Serum samples from 161 patients (98 males/63 females; 92 MM/69 NSCLC) were analyzed for treatment response. At baseline, IL-6 was significantly lower in females (F) versus males (M); lower levels of IL-4 in F and of IL-6 in both sexes significantly correlated with a better ORR, while higher IL-4 and TNF-ɑ values were predictive of a lower ORR in F versus M. One hundred and sixty-five patients were evaluable for survival analysis: at multiple Cox regression, an increased risk of PD was observed in F with higher baseline values of IL-4, sPD-L1 and IL-10, while higher IL-6 was a negative predictor in males. In males, higher levels of GM-CSF predict a longer survival, whereas higher IL-1β predicts a shorter survival. Regardless of sex, high baseline IL-8 values were associated with an increased risk of both PD and death, and high IL-6 levels only with shorter OS. CONCLUSIONS Serum IL-1β, IL-4, IL-6, IL-10, GM-CSF, TNF-ɑ, and sPD-L1 had a significant sex-related predictive impact on ORR, PFS and OS in melanoma and NSCLC patients treated with ICIs. These results will potentially pave the way for new ICI combinations, designed according to baseline and early changes of these cytokines and stratified by sex.

Reappraisal of prognostic factors used in the European Pediatric Soft Tissue Sarcoma Study Group RMS 2005 study for localized rhabdomyosarcoma to optimize risk stratification and generate a prognostic nomogram. Cancer 2024. [PMID: 38400828 DOI: 10.1002/cncr.35258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 01/15/2024] [Accepted: 01/23/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND The objective of this study was to investigate the role of clinical factors together with FOXO1 fusion status in patients with nonmetastatic rhabdomyosarcoma (RMS) to develop a predictive model for event-free survival and provide a rationale for risk stratification in future trials. METHODS The authors used data from patients enrolled in the European Pediatric Soft Tissue Sarcoma Study Group (EpSSG) RMS 2005 study (EpSSG RMS 2005; EudraCT number 2005-000217-35). The following baseline variables were considered for the multivariable model: age at diagnosis, sex, histology, primary tumor site, Intergroup Rhabdomyosarcoma Studies group, tumor size, nodal status, and FOXO1 fusion status. Main effects and significant second-order interactions of candidate predictors were included in a multiple Cox proportional hazards regression model. A nomogram was generated for predicting 5-year event-free survival (EFS) probabilities. RESULTS The EFS and overall survival rates at 5 years were 70.9% (95% confidence interval, 68.6%-73.1%) and 81.0% (95% confidence interval, 78.9%-82.8%), respectively. The multivariable model retained five prognostic factors, including age at diagnosis interacting with tumor size, tumor primary site, Intergroup Rhabdomyosarcoma Studies clinical group, and FOXO1 fusion status. Based on each patient's total score in the nomogram, patients were stratified into four groups. The 5-year EFS rates were 94.1%, 78.4%, 65.2%, and 52.1% in the low-risk, intermediate-risk, high-risk, and very-high-risk groups, respectively, and the corresponding 5-year overall survival rates were 97.2%, 91.5%, 74.3%, and 60.8%, respectively. CONCLUSIONS The results presented here provide the rationale to modify the EpSSG stratification, with the most significant change represented by the replacement of histology with fusion status. This classification was adopted in the new international trial launched by the EpSSG.

Association of tumor-infiltrating lymphocytes with recurrence score in hormone receptor-positive/HER2-negative breast cancer: Analysis of four prospective studies. Eur J Cancer 2023; 195:113399. [PMID: 37950941 DOI: 10.1016/j.ejca.2023.113399] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 10/16/2023] [Accepted: 10/18/2023] [Indexed: 11/13/2023]
Abstract
BACKGROUND The clinical value of tumor infiltrating lymphocytes (TILs) in hormone receptor-positive (HR+)/HER2- breast cancer (BC) may be unearthed by focusing on more biologically aggressive tumors. Here we deepen and describe the correlation between RS and TILs, proposing an immuno-genomic model for HR+ /HER2- BC. METHODS We enrolled T1-T3, N0-N1 BC patients with available RS® and TILs in the context of four multicenter, prospective studies. RS® and TILs were considered as continuous and categorical variables. RS® was categorized into: 0-10 (low risk), 11-25 (intermediate risk) and 26-100 (high risk); TILs were categorized into: low TILs (0-10%), intermediate TILs (11-59%) and high TILs (60-100%). RESULTS 811 patients were included. RS distribution was (n = 810): low risk 22.0%, intermediate risk 61.2%, high risk 16.8%. TIL distribution was (n = 455): low TILs 84.6%, intermediate TILs 13.6% and high TILs 1.8%. A significant, weak positive, linear correlation was found between continuous TILs and RS (Pearson coefficient=0.223, p < 0.001). When considering RS and TILs categories, tumors with intermediate/high TIL levels significantly enriched the high RS subgroup (p = 0.006). This was confirmed both within Luminal A and Luminal B cohorts. Among high-RS patients, 16.7% of Luminal A and 26.7% of Luminal B tumors had intermediate/high TILs. CONCLUSIONS We observed that RS® and TILs capture only slightly overlapping information on the biology of HR+ /HER2- tumor microenvironment. We demonstrated the feasibility of combining RS and TILs into a composite immuno-genomic model, which may serve the purpose of guiding and focalizing patient selection in the further development of immunotherapy strategies for Luminal-like disease.

Abstract
Despite advances in the therapy of Central Nervous System (CNS) malignancies, treatment of glioblastoma (GB) poses significant challenges due to GB resistance and high recurrence rates following post-operative radio-chemotherapy. The majority of prognostic and predictive GB biomarkers are currently developed using tumour samples obtained through surgical interventions. However, the selection criteria adopted by different neurosurgeons to determine which cases are suitable for surgery make operated patients not representative of all GB cases. Particularly, geriatric and frail individuals are excluded from surgical consideration in some cancer centers. Such selection generates a survival (or selection) bias that introduces limitations, rendering the patients or data chosen for downstream analyses not representative of the entire community. In this review, we discuss the implication of survivorship bias on current and novel biomarkers for patient selection, stratification, therapy, and outcome analyses.

The predictive role of intolerance of uncertainty and trait of worry in breast cancer patients: A prospective, observational, single-center clinical study. Front Psychol 2023; 14:1092060. [PMID: 37138973 PMCID: PMC10149753 DOI: 10.3389/fpsyg.2023.1092060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Accepted: 03/30/2023] [Indexed: 05/05/2023] Open
Abstract
Background Breast cancer diagnosis and treatment compromise well-being in a pervasive way, and negative consequences may remain after recovery. The psychological side of breast cancer has been extensively investigated; however, the role of intrusive thoughts and intolerance of uncertainty have been studied less systematically. Objectives The present study aimed to prospectively evaluate worry content, depression, anxiety, and post-traumatic stress symptoms and to define the role of the trait of worry and intolerance of uncertainty (IU) related to breast cancer. Methods Patients with their first breast cancer diagnosis were enrolled in a single-center, prospective observational trial. The trait of worry and IU were assessed using the Penn State Worry Questionnaire (PSWQ) and the Intolerance of Uncertainty Scale-Revised (IUS-R). The psychological aspects were evaluated using the Worry Domains Questionnaire (WDQ), the Beck Anxiety (BAI), Beck Depression Inventory-II (BDI-II), and the Impact of Event Scale-Revised (IES-R). Questionnaires were administered in a randomized sequence at diagnosis (T0), 3 months post-diagnosis (T1), and 12 months post-diagnosis (T2). Results One hundred and fifty eligible patients were enrolled in the study and provided the T0 assessment. Further compliance rates were 57% at T1 and 64% at T2. All patients showed a significant and continuous increase in the IES-R scale (p < 0.0001) from diagnosis to the end of the study, while no significant changes were observed for the WDQ, BAI, and BDI-II scales. The clinical PSWQ levels and/or high levels of the IUS-R score were the only variables that aided the distinction between patients who maintain high levels of depression, anxiety, and post-traumatic disorders and those who did not. Conclusion An early assessment of the components of the trait of worry and intolerance of uncertainty could be critical in identifying patients with a higher psychopathological risk. Furthermore, if future studies confirm the present findings, support and monitoring throughout the prognosis may present crucial benefits, and possibly affect the course of treatment.

Role of SAMITAL in the Prevention and Treatment of Chemo-Radiotherapy-Induced Oral Mucositis in Head and Neck Carcinoma: A Phase 2, Randomized, Double-Blind, Placebo-Controlled Clinical Trial (ROSAM). Cancers (Basel) 2022; 14:cancers14246192. [PMID: 36551677 PMCID: PMC9776559 DOI: 10.3390/cancers14246192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 12/12/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND In patients affected by head and neck squamous cell carcinoma, the onset of severe oral mucositis is a decisive factor in completing concurrent chemo-radiotherapy, and few interventions have demonstrated a modest benefit. The primary aim of this clinical study was to evaluate the role of SAMITAL in reducing the incidence of severe mucositis induced by concurrent chemo-radiotherapy; the secondary aims were the tolerability and patient-reported quality of life measures. METHODS Patients were randomized to receive SAMITAL granules for oral suspension of 20 mL, four-time daily or matching placebo in a 1:1 fashion using a stratified-block randomization scheme by disease site and type of chemotherapy. The SAMITAL/placebo was dispensed at the baseline visit and at each weekly visit following radiotherapy initiation. Patients were subjected to weekly endoscopic evaluations to assess the presence of mucositis. In addition, patient-reported outcomes were measured. RESULTS Among the 116 patients treated with a median total dose of 66 Gy, 59 were randomized to SAMITAL and 57 to placebo. Overall, the incidence of severe mucositis was 51.7%, with 45.8% in the SAMITAL and 57.9% in the placebo arm (OR = 0.6; 95% CI: 0.3-1.3). After chemo-radiotherapy, patients randomized to SAMITAL reported significantly lower xerostomia, coughing and swallowing scores and a better quality of life. CONCLUSION SAMITAL did not significantly reduce the incidence of severe mucositis in all studied populations. However, the lower rate of mucositis, together with a significantly better quality of life, suggested that a clinical benefit existed. This trial is registered with the EU Clinical Trials Register database, number 2012-002046-20, and with ClinicalTrials.gov, NCT01941992.

Abstract
Abstract
Glioblastoma (GBM) has activation of multiple signaling pathways in the tumor microenvironment, including the receptor tyrosine kinases, VEGFR, FGFR and PDGFR. The potential response to anti-angiogenic agents makes GBM an attractive target for regorafenib (REG). Antitumor activity of REG in recurrent GBM patients was shown in the REGOMA trial. Interestingly, in “in vivo” studies, beneficial effects were observed with the combination of REG and temozolomide (TMZ) in subcutaneously xenografts. This phase I open-label multicentric study will evaluate the addition of REG to standard of care treatment with TMZ as adjuvant therapy (cohort A), and in combination with TMZ+RT as concomitant therapy (cohort B), in newly diagnosed MGMT-methylated, IDH wildtype GBM patients. Primary objectives are: to determine the safety and tolerability of REG and to establish the maximum tolerated dose (MTD) of REG in those two cohorts. Secondary objectives are: assessment of pharmacokinetics of REG, TMZ and possible pharmacokinetic interactions between TMZ and REG (cohort A); assessment of preliminary antitumor activity; evaluation of quality of life during the treatment. The dose escalation will be explored according to a “3 + 3” design, starting from cohort A and following 3 dose levels of REG [80 mg, 120 mg and 160 mg; level -1 40 mg will be evaluated in case of Dose-Limiting Toxicity (DLT) during REG 80 mg]. After finding the MTD in cohort A, the cohort B dose escalation will start, exploring escalating oral doses of REG in combination with concomitant TMZ+RT (60 Gy/30 fractions); in the adjuvant phase of cohort B, REG will be given (in association to TMZ) at MTD shown in the prior adjuvant phase dose escalation.The DLT evaluation period will be two cycles from the start of cycle 1 of adjuvant or from day 1 to last day of the concomitant phase. Approximately 36 subjects will be enrolled.

Abstract
2549 Background: ICIs lead to durable response and a significant survival improvement in a limited number of advanced stage Mel and NSCLC pts. The identification of predictive circulating biomarkers could be a promising tool to optimize pts’ selection and outcome for ICIs treatment. Methods: This is a prospective real-world study enrolling advanced stage Mel and NSCLC pts referred to four Italian Centers and treated with ICIs. The primary endpoint is to verify the presence of an association between circulating cytokines (IL-1b, IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, TNFα, GM-CSF) and disease control rate (DCR), progression free survival (PFS) and overall survival (OS). Pts undergo a blood collection, before every cycle for 6 cycles (T1-T6) and at tumor assessment till disease progression (PD) or for 2 years. Biomarker levels were assessed by Luminex xMAP based technology using R&D High Sensitivity kits. Each marker was categorized according to high and low levels by maximizing its discriminative ability, and the association with the outcome was tested in univariate and multiple analyses. Results: We report preliminary results on the T1-T2 blood samples from the first 78 enrolled pts (32 females/46 males; 43 Mel/35 NSCLC; median age 69 years). Serum IL-6, IL-8 and IL-10 were significantly higher at T1 and T2 in pts with PD (Kruskal-Wallis test). The median relative increase (RI) of IL-8 was 32% and 2% in pts with PD and disease control (DC), respectively (p = 0.0001). At multiple logistic analysis, IL-6 and IL-8 at T2 and the RI of IL-8 were independent factors predicting the probability of DC, with an overall accuracy of 83.8%. High levels of IL-6 and IL-8 at T2 were significantly associated with a low probability of DC (OR = 0.13, 95%CI: 0.03-0.52 and OR = 0.09, 95%CI: 0.02-0.37, respectively), and the RI showed a significantly lower probability of DC (OR = 0.14, 95%CI: 0.02-0.58). With a median follow-up of 10.6 months (m), mPFS and mOS were 5.8 m, 95%CI: 2.3-7.4 and 8.3 m, 95%CI: 4.0-13.8 for NSCLC; 6.9 m, 95%CI: 2.8-15.9 and 12.6 m, 95%CI: 4.7-NE for Mel pts, respectively. In the multiple Cox model, elevated IL-6 and IL-8 at T1 (HR = 3.03, 95%CI: 1.55-6.37, HR = 2.86, 95%CI: 1.46-5.63), elevated IL-10 at T2 (HR = 2.86, 95%CI: 1.39-5.94), and a RI of IL-8 (HR = 4.22, 95%CI: 1.85-11.21) remained significantly associated with a worse PFS. Higher levels of IL-6 (HR = 3.85, 95%CI: 1.13-20.0) and IL-8 (HR = 4.29, 95%CI: 1.98-9.83) at T2 and a RI of IL-8 (HR = 3.06, 95%CI: 1.43-6.72) remained significantly associated with a worse OS. Conclusions: High serum levels of IL-8 and IL-6 at T2 of ICI, combined with an increase of IL-8 from baseline, are strong predictors of PD, PFS, OS, in pts with advanced Mel and NSCLC. The role of the other cytokines tested, their time fluctuations and associations with clinical prognostic factors, gender, and immuno-related adverse events will be presented at the meeting.

Abstract
PURPOSE The role of immunotherapy in hormone receptor (HR)-positive, HER2-negative breast cancer is underexplored. PATIENTS AND METHODS The neoadjuvant phase II GIADA trial (NCT04659551, EUDRACT 2016-004665-10) enrolled stage II-IIIA premenopausal patients with Luminal B (LumB)-like breast cancer (HR-positive/HER2-negative, Ki67 ≥ 20%, and/or histologic grade 3). Patients received: three 21-day cycles of epirubicin/cyclophosphamide followed by eight 14-day cycles of nivolumab, triptorelin started concomitantly to chemotherapy, and exemestane started concomitantly to nivolumab. Primary endpoint was pathologic complete response (pCR; ypT0/is, ypN0). RESULTS A pCR was achieved by 7/43 patients [16.3%; 95% confidence interval (CI), 7.4-34.9]; the rate of residual cancer burden class 0-I was 25.6%. pCR rate was significantly higher for patients with PAM50 Basal breast cancer (4/8, 50%) as compared with other subtypes (LumA 9.1%; LumB 8.3%; P = 0.017). Tumor-infiltrating lymphocytes (TIL), immune-related gene-expression signatures, and specific immune cell subpopulations by multiplex immunofluorescence were significantly associated with pCR. A combined score of Basal subtype and TILs had an AUC of 0.95 (95% CI, 0.89-1.00) for pCR prediction. According to multiplex immunofluorescence, a switch to a more immune-activated tumor microenvironment occurred following exposure to anthracyclines. Most common grade ≥3 treatment-related adverse events (AE) during nivolumab were γ-glutamyltransferase (16.7%), alanine aminotransferase (16.7%), and aspartate aminotransferase (9.5%) increase. Most common immune-related AEs were endocrinopathies (all grades 1-2; including adrenal insufficiency, n = 1). CONCLUSIONS Luminal B-like breast cancers with a Basal molecular subtype and/or a state of immune activation may respond to sequential anthracyclines and anti-PD-1. Our data generate hypotheses that, if validated, could guide immunotherapy development in this context.

Paediatric non-rhabdomyosarcoma soft tissue sarcomas: the prospective NRSTS 2005 study by the European Pediatric Soft Tissue Sarcoma Study Group (EpSSG). THE LANCET CHILD & ADOLESCENT HEALTH 2021; 5:546-558. [PMID: 34214481 DOI: 10.1016/s2352-4642(21)00159-0] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 05/10/2021] [Accepted: 05/11/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND A standardised approach to treatment of paediatric non-rhabdomyosarcoma soft tissue sarcomas (NRSTS), which account for about 4% of childhood cancers, is still lacking. We report the results of the NRSTS 2005 protocol developed specifically by the European Pediatric Soft Tissue Sarcoma Study Group (EpSSG) to determine a risk-adapted multimodal standard of care for this group of tumours. METHODS The EpSSG NRSTS 2005 study included two prospective, non-randomised, historically controlled trials (one on localised adult-type NRSTS and the other on localised synovial sarcoma) done at 100 academic centres and hospitals in 14 countries. Patients younger than 21 years with a pathologically proven diagnosis of synovial sarcoma or an adult-type NRSTS, no evidence of metastatic disease, no previous treatment other than primary surgery, and diagnostic specimens available for pathological review were included. Patients were stratified by surgical stage, tumour size, nodal involvement, tumour grade (for adult-type NRSTS), and tumour site (for synovial sarcoma). Patients were then divided into four treatment groups: surgery alone, adjuvant radiotherapy, adjuvant chemotherapy (with or without radiotherapy), or neoadjuvant chemotherapy (with or without radiotherapy). The main chemotherapy regimen was ifosfamide (3·0 g/m2 intravenously per day for 3 days) plus doxorubicin (37·5 mg/m2 intravenously per day for 2 days); only ifosfamide (3·0 g/m2 intravenously per day for 2 days) was given concomitantly with radiotherapy (delivered with three-dimensional conformal external beam technique, using conventional fractionation [1·8 daily fractions, 5 days per week] at a dose of 50·4 Gy or 54·0 Gy, to a maximum of 59·4 Gy). The number of chemotherapy cycles ranged from three to seven depending on the stage of the disease. The primary outcomes were event-free survival and overall survival. This study has been completed, and is registered under EudraCT, 2005-001139-31. FINDINGS Between May 31, 2005, and Dec 31, 2016, 1321 patients were enrolled, of whom 569 (206 with synovial sarcoma and 363 with adult-type NRSTS), with a median age of 12·6 years (IQR 8·2-14·9), were included in this analysis. With a median follow-up of 80·0 months (IQR 54·3-111·3) for the 467 patients alive, 5-year event-free survival was 73·7% (95% CI 69·7-77·2) and 5-year overall survival was 83·8% (95% CI 80·3-86·7). 5-year event-free survival was 91·4% (95% CI 87·0-94·4) and 5-year overall survival was 98·1% (95% CI 95·0-99·3) in the surgery alone group (n=250); 75·5% (46·9-90·1) and 88·2% (60·6-96·9) in the adjuvant radiotherapy group (n=17); 65·6% (54·8-74·5) and 75·8% (65·3-83·5) in the adjuvant chemotherapy group (n=93); and 56·4% (49·3-63·0) and 70·4% (63·3-76·4) in the neoadjuvant chemotherapy group (n=209). Reported severe adverse events included one case of generalised seizures (probably related to ifosfamide) and six cases of secondary tumours. INTERPRETATION Findings from the EpSSG NRSTS 2005 study help to define the risk-adapted standard of care for this patient population. Adjuvant treatment can be safely omitted in the low-risk population (classified here as the surgery alone group). Improving the outcome for patients with high-risk, initially resected adult-type NRSTS and those with initially unresectable disease remains a major clinical challenge.

Abstract
BACKGROUND Patients with glioblastoma (GBM) have a dramatically poor prognosis. The recent REGOMA trial suggested an overall survival (OS) benefit of regorafenib in recurrent GBM patients. Considering the extreme genetic heterogeneity of GBMs, we aimed to identify molecular biomarkers predictive of differential response to the drug. METHODS Total RNA was extracted from tumor samples of patients enrolled in the REGOMA trial. Genome-wide transcriptome and micro (mi)RNA profiles were associated with patients' OS and progression-free survival. RESULTS In the first step, a set of 11 gene transcripts (HIF1A, CTSK, SLC2A1, KLHL12, CDKN1A, CA12, WDR1, CD53, CBR4, NIFK-AS1, RAB30-DT) and 10 miRNAs (miR-93-5p, miR-203a-3p, miR-17-5p, let-7c-3p, miR-101-3p, miR-3607-3p, miR-6516-3p, miR-301a-3p, miR-23b-3p, miR-222-3p) was filtered by comparing survival between regorafenib and lomustine arms. In the second step, a mini-signature of 2 gene transcripts (HIF1A, CDKN1A) and 3 miRNAs (miR-3607-3p, miR-301a-3p, miR-93-5p) identified a subgroup of patients showing prolonged survival after regorafenib administration (median OS range, 10.6-20.8 mo). CONCLUSIONS The study provides evidence that a signature based on the expression of 5 biomarkers could help identify a subgroup of GBM patients exhibiting a striking survival advantage when treated with regorafenib. Although the presented results must be confirmed in larger replication cohorts, the study highlights potential biomarker options to help guide the clinical decision among regorafenib and other treatments in patients with relapsing GBM.

Alveolar rhabdomyosarcoma with regional nodal involvement: Results of a combined analysis from two cooperative groups. Pediatr Blood Cancer 2021; 68:e28832. [PMID: 33245207 PMCID: PMC8414760 DOI: 10.1002/pbc.28832] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 10/26/2020] [Accepted: 11/08/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Treatment of children and adolescents with alveolar rhabdomyosarcoma (ARMS) and regional nodal involvement (N1) have been approached differently by North American and European cooperative groups. In order to define a better therapeutic strategy, we analyzed two studies conducted between 2005 and 2016 by the European paediatric Soft tissue sarcoma Study Group (EpSSG) and Children's Oncology Group (COG). METHODS We retrospectively identified patients with ARMS N1 enrolled in either EpSSG RMS2005 or in COG ARST0531. Chemotherapy in RMS2005 comprised ifosfamide + vincristine + dactinomycin + doxorubicin (IVADo), IVA and maintenance (vinorelbine, cyclophosphamide); in ARST0531, it consisted of either vincristine + dactinomycin + cyclophosphamide (VAC) or VAC alternating with vincristine + irinotecan (VI). Local treatment was similar in both protocols. RESULTS The analysis of the clinical characteristics of 239 patients showed some differences between study groups: in RMS2005, advanced Intergroup Rhabdomyosarcoma Study Group (IRS) and large tumors predominated. There were no differences in outcomes between the two groups: 5-year event-free survival (EFS), 49% (95% confidence interval [CI]: 39-59) and 44% (95% CI: 30-58), and overall survival (OS), 51% (95% CI: 41-61) and 53.6% (95% CI: 40-68) in RMS2005 and ARST0531, respectively. In RMS2005, EFS of patients with FOXO1-positive tumors was significantly inferior to those with FOXO1-negative (49.3% vs 73%, P = .034). In contrast, in ARST0531, EFS of patients with FOXO1-positive tumors was 45% compared with 43.8% for those with FOXO1-negative. CONCLUSIONS The outcome of patients with ARMS N1 was similar in both protocols. However, patients with FOXO1 fusion-negative tumors enrolled in RMS2005 showed a significantly better outcome, suggesting that different strategies of chemotherapy may have an impact in the outcome of this subgroup of patients.

Abstract
Abstract
Background Despite endocrine therapy is the mainstay of treatment for HR+/HER2- metastatic breast cancer (MBC), patients with high disease burden or those at risk of visceral crisis are still offered first-line chemotherapy (CT). Chemotherapy is generally followed by maintenance hormonal therapy. The MAIN-A study is an investigator-driven, randomized phase III trial designed to compare maintenance everolimus (EVE) combined with aromatase inhibitors (AI) versus AI alone in pts with disease control after first-line CT.Methods Postmenopausal pts achieving disease control (stable disease, partial response or complete response) after first-line CT were randomly assigned to EVE 10 mg po daily plus AI or to AI alone. Primary aim was PFS in the ITT. We present here overall survival (OS) results and the impact of tumor characteristics on PFS.Results 110 pts were randomized to EVE+AI (n=52) or to AI (n= 58). Primary aim results have been already presented (Guarneri V, ESMO Breast 2019), showing a non-significant prolongation of median PFS in the ITT population for EVE+AI (9.9 mos vs 7.2 mos, HR 0.764, 95% CI 0.501-1.164. Patients with visceral metastases tended to experience shorter PFS as compared with patients with patients with bone/soft tissues metastases (median 11.1 mos vs 6.4 mos, p=0.0746). The levels of estrogen receptor expression (>or< 50%) did not impact PFS, overall and by treatment arm. At the time of this writing, a total of 61 death events have been recorded. No difference in OS was observed between the two arms (median 33.9 mos for EVE+AI vs 33.5 mos for AI, HR 0.97, 95% CI 0.59-1.61).Conclusions Maintenance EVE+AI did not significantly impact on the outcome of metastatic breast cancer patients deemed suitable for first line chemotherapy.

Abstract
BACKGROUND Rhabdomyosarcoma (RMS) is the most common form of soft tissue sarcoma in children. We report the results of the European paediatric Soft tissue sarcoma Study Group (EpSSG) RMS 2005 study, which prospectively evaluated the reduction of chemotherapy in patients with embryonal RMS (ERMS) after initial surgery. METHODS Between October 2005 and December 2016, all patients with localised ERMS with an initial microscopically complete resection (IRS group I) with lymph node-negative (N0) were prospectively enrolled in the low-risk (n = 70, subgroup A; age < 10 years and tumour size ≤ 5 cm) or standard-risk group (n = 108, subgroup B; age ≥ 10 years or tumour size > 5 cm. Subgroup A received 8 courses of vincristine and dactinomycin (VA) for 22 weeks; subgroup B received 4 courses of VA with ifosfamide (IVA) and 5 courses of VA for 25 weeks. RESULTS The 5-year event-free survival (EFS) and overall survival (OS) were 90.8% (95% confidence interval [CI]: 85.0-94.4) and 95.7% (95% CI: 90.5-98.1), respectively (n = 178). The EFS and OS were 95.5% (95% CI: 86.8-98.5) and 100% (subgroupA), and 87.8% (95% CI: 79.3-93.0) and 93.0% (95% CI: 84.8-96.8)(subgroup B), respectively. Bearman stage 2 veno-occlusive disease (VOD) occurred in 4 very young patients. CONCLUSION VA treatment for 8 courses was effective and well tolerated by the subgroup of patients with low-risk ERMS (group A). Four courses of IVA and 5 courses of VA instead of 9 courses of IVA also has very good results. Careful monitoring for liver toxicity is important in very young patients.

Abstract
BACKGROUND Patient-reported outcomes associated with different bowel reconstruction techniques following anterior resection for rectal cancer are still a matter of debate. OBJECTIVE This study aimed to assess quality of life and bowel function in patients who underwent colonic J-pouch or straight colorectal anastomosis reconstruction after low anterior resection. DESIGN Bowel function and quality of life were assessed within a multicenter randomized trial. Questionnaires were administered before the surgery (baseline) and at 6, 12, and 24 months after surgery. SETTINGS Patients were enrolled by 19 centers. The enrollment started in October 2009 and was stopped in February 2016. The study was registered at www.clinicaltrials.gov (Identifier: NCT01110798). PATIENTS Patients who underwent low anterior resection for primary mid-low rectal cancer and who were randomly assigned in a 1:1 ratio to receive either stapled colonic J-pouch or straight colorectal anastomosis were selected. MAIN OUTCOME MEASURES The primary outcomes measured were quality of life and bowel function. RESULTS Of the 379 patients who were evaluable, 312 (82.3%) completed the baseline, 259 (68.3%) the 6-month, 242 (63.9%) the 12-month, and 199 (52.5%) the 24-month assessment. Bowel functioning and quality of life did not significantly differ between arms for almost all domains. The total bowel function score, the urgency, and the stool fractionation scores significantly worsened after surgery and remained impaired over time in both arms (p < 0.0032), whereas constipation improved after surgery but recovered to baseline levels from 1 year onward (p < 0.0036). All patients showed a significant and continuous improvement in emotional functioning (p < 0.0013) and future perspective (p < 0.0001) from baseline to the end of the study. LIMITATIONS Limitations of the study include missing data, which increased over time; the possibility that some treatments have slightly changed since the study was conducted; and investigators not blind to treatment allocation. CONCLUSION The findings of this study do not support the routine use of colonic J-pouch reconstruction in patients with rectal cancer who undergo a low anterior resection.

Dermatofibrosarcoma protuberans in children and adolescents: The European Paediatric Soft Tissue Sarcoma Study Group prospective trial (EpSSG NRSTS 2005). Pediatr Blood Cancer 2020; 67:e28351. [PMID: 32558231 DOI: 10.1002/pbc.28351] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Revised: 03/11/2020] [Accepted: 03/24/2020] [Indexed: 11/12/2022]
Abstract
BACKGROUND As dermatofibrosarcoma protuberans (DFSP) are rare with no prospective series within paediatric sarcoma trials, the European Paediatric Soft Tissue Sarcoma Study Group (EpSSG) examined the clinical data and outcomes of DFSP enrolled in a multinational study of non-rhabdomyosarcoma soft tissue sarcomas (NRSTS). PATIENTS AND METHODS Forty-six patients with confirmed DFSP were enrolled into the EpSSG NRSTS 2005 study. All had surgical resection and none had any further therapy at diagnosis. RESULTS The median age at diagnosis was 6.9 years (range 0.4-17.5). All patients had localised disease, and the majority had small <5 cm tumours (93%), and 76% had Intergroup Rhabdomyosarcoma Study (IRS) I tumours. All patients had up front surgery, 32 requiring two operations. There were 11 patients with IRS II tumours, of which only two went on to have a local recurrence. After a median follow up of 49.0 months (range 4.2-130.9), all patients were alive at the time of this report, with 5-year event-free survival of 92.6% (CI 78.8-97.6) with a 100% overall survival. CONCLUSION This report demonstrates the ability to run prospective paediatric studies in NRSTS in multiple European countries, with reasonable numbers of DFSP patients, with few events and no deaths, and hence excellent outcomes.

Paratesticular rhabdomyosarcoma-Impact of locoregional approach on patient outcome: A report from the European paediatric Soft tissue sarcoma Study Group (EpSSG). Pediatr Blood Cancer 2020; 67:e28479. [PMID: 32573979 DOI: 10.1002/pbc.28479] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 05/14/2020] [Accepted: 05/18/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND Paratesticular rhabdomyosarcoma (PT RMS) is rare compared to benign scrotal pathology. Inappropriate first surgery (InFS) required supplementary treatment to maintain excellent outcomes. Initial staging of regional lymph nodes is important. The aim of this study was to determine to what extent the quality of locoregional approach impacted on patient morbidity and survival. DESIGN/METHODS Analysis was performed on all nonmetastatic PT RMS patients enrolled in the European paediatric Soft tissue sarcoma Study Group (EpSSG) RMS 2005 protocol. Aspects assessed were adherence to surgical guidelines and impact of protocol violations, relapse analysis, and survival outcomes. RESULTS Analysis was performed on 237 patients, with median follow up of 67.1 months. Median age was 9.0 years. InFS occurred in 75 of 237 (32%) patients. InFS required intensified chemotherapy (10) and local therapy. After InFS, 61 required primary reexcision and five delayed surgery. Of 26 recurrences, the risk of relapse was higher in patients ≥10 years (21/26) and was mainly locoregional in 16 of 26 recurrences (± metastatic). Sixteen of 26 died with 14 of 16 patients ≥10 years. Nodal relapse neither occurred when N1 nodes were identified at diagnosis, nor after surgical staging. Five-year overall survival (OS) at age <10 years versus ≥10 years was 98.1 and 86.7%, respectively (P = .0013). Event-free survival (EFS) at age <10 years versus ≥10 years was 95.8 and 79.6%, respectively (P = .0004). OS and EFS did not highlight a significant difference in patients undergoing appropriate versus InFS (P = .8479, P = .2780, respectively). CONCLUSIONS InFS required intensified therapy to maintain excellent OS and EFS, so better anticipation of malignancy is required. Surgical staging of the retroperitoneal lymph nodes should be performed in patients ≥10 years old.

Abstract
Rhabdomyosarcoma of the extremities present with two main challenges: correct evaluation of initial regional nodal involvement and define adequate local treatment. METHODS Pediatric patients with localized rhabdomyosarcoma of the extremity included in the EpSSG-RMS2005 study between 2005 and 2014 were evaluated for staging, treatment, and survival. The outcome was compared to the preceding European SIOP-MMT studies. RESULTS Of the 162 patients included, histology was unfavorable in 113 (70%), 124 (77%) were younger than 10 years, 128 (79%) were IRS III, and 47 (29%) were node-positive. A regional node biopsy was performed in 97 patients (60%) and modified the lymph node stage in 15/97 (16%). Primary and delayed surgery was performed in 155 (96%) and radiotherapy delivered in 118 (73%) patients. Relapse occurred in 61 cases (38%), local in 14 (23%), regional in 13 (21%), distant in 22 (36%), and combined relapse in 12 (20%) with five progressive diseases (8%) and four secondary tumors (7%). Five-year event free (EFS) and overall survival (OS) were 58.4% (95%CI, 50.3-65.7) and 71.7% (63.6-78.4), respectively. In the previous studies MMT89 and MMT95, tumor surgery was performed in 32/53 (60%) and 74/82(90%), respectively, and radiotherapy delivered in 13/53 (25%) and 26/82 (30%), respectively. Five-year EFS and OS were 35.6%, and 50.3% in MMT89 and 54.3% and 68.2% in the MMT95 study. CONCLUSIONS Even if the lymph node staging was not always complete according to the RMS2005 protocol, node sampling changed lymph node status in a significant number of patients. Despite the higher rate of patients treated with locoregional radiotherapy, survival in RMS2005 did not improve compared to the previous European SIOP-MMT95 study.

Abstract
PURPOSE Preclinical studies show that antiangiogenic therapy exacerbates tumor glycolysis and activates liver kinase B1/AMP kinase (AMPK), a pathway involved in the regulation of tumor metabolism. We investigated whether certain metabolism-related in situ biomarkers could predict benefit to regorafenib in the phase II randomized REGOMA trial. PATIENTS AND METHODS IHC and digital pathology analysis were used to investigate the expression in glioblastoma (GBM) sections of monocarboxylate transporter 1 and 4 (MCT1 and MCT4), associated with OXPHOS and glycolysis, respectively, phosphorylated AMPK (pAMPK), and phosphorylated acetyl-CoA carboxylase (pACC), a canonical target of AMPK activity. The status of each biomarker was associated with clinical endpoints, including overall survival (OS) and progression-free survival (PFS) in patients with relapsed GBM treated either with regorafenib or lomustine. RESULTS Between November 2015 and February 2017, 119 patients were enrolled (n = 59 regorafenib and n = 60 lomustine) and stratified for surgery at recurrence, and baseline characteristics were balanced. Biomarker analysis was performed in 84 patients (71%), including 42 patients of the regorafenib arm and 42 patients of the lomustine arm. Among all markers analyzed, only pACC showed predictive value in terms of OS. In fact, median OS was 9.3 months [95% confidence interval (CI), 5.6-13.2] for regorafenib and 5.5 months (95% CI, 4.2-6.6) for lomustine for pACC-positive patients, HR, 0.37 (95% CI, 0.20-0.70); log rank P = 0.0013; test for interaction = 0.0453. No statistically significant difference was demonstrated for PFS according to pACC status. CONCLUSIONS We found that AMPK pathway activation is associated with clinical benefit from treatment with regorafenib in relapsed GBM.

Abstract
582 Background: The CHER-LOB randomized phase II study showed that the combination of lapatinib and trastuzumab plus chemotherapy increases the pathologic complete response (pCR) rate compared with chemotherapy plus either trastuzumab or lapatinib. Here we report the results of survival analysis according to treatment arm and pCR. Methods: The CherLOB study randomized 121 HER2-positive, stage II-IIIA breast cancer patients to anthracyclines/taxane-based chemotherapy plus trastuzumab, lapatinib, or both. After surgery, patients received adjuvant trastuzumab for up to 1 year. The primary end point of the study was met, with a relative increase of 80% in the pCR rate achieved with chemotherapy plus trastuzumab and lapatinib compared with chemotherapy plus either trastuzumab or lapatinib (Guarneri, J Clin Oncol 2012). Relapse-free survival (RFS) was calculated from randomization to breast cancer recurrence (locoregional or distant) or death from any cause, whichever first. Overall survival (OS) was calculated from randomization to death from any cause. Results: At a median follow up of 8.8 years, RFS rates at 5 years were: 85.8% in the trastuzumab + lapatinib arm, 77.8% in the trastuzumab arm, 78.1% in the lapatinib arm (log-rank p = 0.160). Patients treated with dual HER2 blockade (trastuzumab + lapatinib arm) experienced numerically better RFS as compared to patients treated with single HER2 blockade (trastuzumab arm and lapatinib arm combined): 5-yr RFS 85.8% vs 78.0%, log-rank p = 0.087; HR = 0.51, 95% CI 0.23-1.12, p = 0.093. The achievement of pCR was a strong prognostic factor. 5-yr RFS rate was 97.3% for pCR patients vs 72.9% for non-pCR patients (log-rank p < 0.001, HR = 0.12, 95% CI 0.03-0.49, p = 0.003); similar significant results were observed in both the estrogen receptor-negative and estrogen-receptor positive subgroups. OS was also improved in pCR patients: 8-yr OS rates were 97.2% vs 80.0% for non pCR patients (log-rank p = 0.028, HR = 0.14, 95% CI 0.02-1.08, p = 0.060). Conclusions: In the Cher-LOB study, there was a not statistically significant signal for a better RFS for patients who received dual HER2 blockade with trastuzumab and lapatinib plus chemotherapy as compared to patients treated with single anti-HER2 agent (trastuzumab or lapatinib) plus chemotherapy. Patients achieving a pCR had longer RFS and OS as compared to non-pCR patients. Clinical trial information: NCT00429299 .

TPS598 Background: Chemotherapy represents, today, the only treatment option for triple negative breast cancer (TNBC) and still a considerable proportion of pts with primary TNBC experience disease relapse. The risk is particularly high in the presence of poor prognostic features, such as more advanced stage and, for pts treated with neoadjuvant chemotherapy, failure to achieve a pCR. Recent evidence suggest that immunotherapy can play a major role in TNBC pts. Methods: The A-BRAVE trial is an investigator-driven trial sponsored by the University of Padova (Dept. of Surgery, Oncology and Gastroenterology). This is a phase III, multicentric, randomized adjuvant study that compares 1 year of treatment with the anti PD-L1 avelumab vs observation for pts who completed treatment with radical intent for primary TNBC including surgery and chemotherapy. The study enrolls pts in two strata: -Stratum A: primary TNBC pts who completed surgery followed by adjuvant, defined according to one of the following stage categories: if pN2, any pT; if pN1, pT > 2 cm; if pN0, pT > 5 cm. -Stratum B: primary TNBC pts who completed neoadjuvant chemotherapy followed by surgery who did not achieve pCR. Pts who also received additional adjuvant chemotherapy for no more than 6 months are eligible in Stratum B, after the completion of the adjuvant chemotherapy. Pts are randomized (1:1, balanced for strata A and B) to receive Avelumab 10 mg/kg I.V. q2w for 1 year or to observation. The first and second co-primary endpoints are disease-free survival (DFS) in all pts and DFS in Stratum B pts. With a planned sample size of n = 474 pts the trial has 90% power to detect a HR = 0.60 for the first co-primary endpoint (n = 172 events required). Taking into account that the percentage of patients enrolled in the stratum B could range from 70 to 80%, there will be 70-79% power to detect a HR = 0.60 at alpha allocated in this patient subgroup (second co-primary endpoint). Secondary objectives include: DFS in PD-L1 positive pts, overall survival, safety, biomarkers. Tumor tissue, plasma samples and fecal samples are collected for biomarker analysis. The study is currently recruiting across 73 sites in Italy and UK. As of February 2020, n = 349 pts have been enrolled. EUDRACT 2016‐000189‐45. The authors present the A-BRAVE trial in progress on behalf of Italian and UK investigators. Clinical trial information: NCT02926196 .

Abstract
PURPOSE Interpatient clinical variability in soft-tissue sarcomas (STS) highlights the need for novel prognostic markers supporting patient risk stratification. As sarcomas might exhibit a more mesenchymal or a more epithelial state, we focused on epithelial-mesenchymal and mesenchymal-epithelial transitions (EMT/MET) for prognostic clues, and selected three histotypes with variable aggressiveness. EXPERIMENTAL DESIGN The expression of EMT/MET-related factors was measured by qRT-PCR in 55 tumor samples from patients with leiomyosarcoma, myxofibrosarcoma, or undifferentiated pleomorphic sarcoma. The identified marker was further evaluated by IHC in 31 leiomyosarcomas and by measuring its circulating levels in 67 patients. The prognostic value of a sarcoma-tailored EMT score was analyzed. Epirubicin chemosensitivity and migration were studied in primary STS cultures. Associations with overall survival (OS) were assessed using Kaplan-Meier and Cox regression methods. RESULTS High expression of periostin, a mesenchymal matricellular protein, in sarcoma tissues (P = 0.0024), its high stromal accumulation in leiomyosarcomas (P = 0.0075), and increased circulation (>20 ng/mL, P = 0.0008) were associated with reduced OS. High periostin expression [HR 2.9; 95% confidence interval (CI), 1.3-6.9; P = 0.0134] and circulation (HR 2.6; 95% CI, 1.3-5.1; P = 0.0086), and a mesenchymal EMT score (mesenchymal vs. transitioning; HR, 5.2; 95% CI, 2.1-13.0, P = 0.0005) were associated with increased risk in multivariable models. An intrinsic or induced mesenchymal state enhanced chemoresistance and migration in sarcoma cell lines. CONCLUSIONS Although limited to a pilot study, these findings suggest that periostin might contribute prognostic information in the three studied STS histotypes. Moreover, a transitioning EMT score measured in the tumor might predict a less active and a more chemosensitive disease.

Inflammatory myofibroblastic tumor: The experience of the European pediatric Soft Tissue Sarcoma Study Group (EpSSG). Eur J Cancer 2020; 127:123-129. [PMID: 32007712 DOI: 10.1016/j.ejca.2019.12.021] [Citation(s) in RCA: 57] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Accepted: 12/16/2019] [Indexed: 12/27/2022]
Abstract
INTRODUCTION We report the clinical findings and results of treatment in the cohort of patients with inflammatory myofibroblastic tumor (IMT) managed according to the European pediatric Soft Tissue Sarcoma Study Group (EpSSG) protocol from 2005 to 2016. METHODS Patients (<25 years old) with IMT from 9 countries were prospectively registered via a web-based system. Their histology was reviewed by a national/international pathology panel. Immunohistochemistry for ALK assessment was mandatory. No adjuvant therapy was suggested for initially resected tumors. No specific systemic therapy was recommended for cases of unresectable disease. RESULTS Among 80 cases of IMT registered, 20 were excluded because pathology review led to a revised diagnosis. Of the remaining 60 patients (median age 9.5 years), 59 had localized, and 1 had multifocal/metastatic disease. The lung was the primary site in 14 cases. IMT developed as a second tumor in 2 cases. Forty cases were ALK-positive, and 20 were ALK-negative. Five-year event-free survival (EFS) and overall survival (OS) were 82.9% and 98.1%, respectively. No clinical variables correlated statistically with the outcome: survival was the same for ALK-positive and ALK-negative cases. The overall response to systemic therapy was 64%: 8/10 cases responded to vinblastine-methotrexate chemotherapy, and 5/5 to ALK-inhibitors. CONCLUSIONS This study demonstrated a good overall prognosis for IMT, even for initially unresectable disease and in ALK-negative cases. Chemotherapy is still a valid option for advanced disease. Larger studies involving both pediatric and adult patients are needed to clarify the role of ALK inhibitors.

Is surveillance imaging in pediatric patients treated for localized rhabdomyosarcoma useful? The European experience. Cancer 2019; 126:823-831. [PMID: 31750944 PMCID: PMC7027831 DOI: 10.1002/cncr.32603] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 09/26/2019] [Accepted: 09/30/2019] [Indexed: 11/30/2022]
Abstract
Background After the completion of therapy, patients with localized rhabdomyosarcoma (RMS) are subjected to intensive radiological tumor surveillance. However, the clinical benefit of this surveillance is unclear. This study retrospectively analyzed the value of off‐therapy surveillance by comparing the survival of patients in whom relapse was detected by routine imaging (the imaging group) and patients in whom relapse was first suspected by symptoms (the symptom group). Methods This study included patients with relapsed RMS after the completion of therapy for localized RMS who were treated in large pediatric oncology hospitals in France, the United Kingdom, Italy, and the Netherlands and who were enrolled in the International Society of Paediatric Oncology Malignant Mesenchymal Tumor 95 (1995‐2004) study, the Italian Paediatric Soft Tissue Sarcoma Committee Rhabdomyosarcoma 96 (1996‐2004) study, or the European Paediatric Soft Tissue Sarcoma Study Group Rhabdomyosarcoma 2005 (2005‐2013) study. The survival times after relapse were compared with a log‐rank test between patients in the imaging group and patients in the symptom group. Results In total, 199 patients with relapsed RMS were included: 78 patients (39.2%) in the imaging group and 121 patients (60.8%) in the symptom group. The median follow‐up time after relapse was 7.4 years (interquartile range, 3.9‐11.5 years) for survivors (n = 86); the 3‐year postrelapse survival rate was 50% (95% confidence interval [CI], 38%‐61%) for the imaging group and 46% (95% CI, 37%‐55%) for the symptom group (P = .7). Conclusions Although systematic routine imaging is the standard of care after RMS therapy, the majority of relapses were detected as a result of clinical symptoms. This study found no survival advantage for patients whose relapse was detected before the emergence of clinical symptoms. These results show that the value of off‐therapy surveillance is controversial, particularly because repeated imaging may also entail potential harm. This study assesses the clinical value of radiological surveillance imaging in pediatric patients with rhabdomyosarcoma, which is routinely performed after the completion of therapy. In the majority of patients, relapse is detected because of symptoms, and there is no evidence that early detection by imaging results in improved survival.

Vinorelbine and continuous low-dose cyclophosphamide as maintenance chemotherapy in patients with high-risk rhabdomyosarcoma (RMS 2005): a multicentre, open-label, randomised, phase 3 trial. Lancet Oncol 2019; 20:1566-1575. [PMID: 31562043 DOI: 10.1016/s1470-2045(19)30617-5] [Citation(s) in RCA: 111] [Impact Index Per Article: 22.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2019] [Revised: 08/06/2019] [Accepted: 08/19/2019] [Indexed: 12/01/2022]
Abstract
BACKGROUND For more than three decades, standard treatment for rhabdomyosarcoma in Europe has included 6 months of chemotherapy. The European paediatric Soft tissue sarcoma Study Group (EpSSG) aimed to investigate whether prolonging treatment with maintenance chemotherapy would improve survival in patients with high-risk rhabdomyosarcoma. METHODS RMS 2005 was a multicentre, open-label, randomised, controlled, phase 3 trial done at 102 hospitals in 14 countries. We included patients aged 6 months to 21 years with rhabdomyosarcoma who were considered to be at high risk of relapse: those with non-metastatic incompletely resected embryonal rhabdomyosarcoma occurring at unfavourable sites with unfavourable age (≥10 years) or tumour size (>5 cm), or both; those with any non-metastatic rhabdomyosarcoma with nodal involvement; and those with non-metastatic alveolar rhabdomyosarcoma but without nodal involvement. Patients in remission after standard treatment (nine cycles of ifosfamide, vincristine, dactinomycin with or without doxorubicin, and surgery or radiotherapy, or both) were randomly assigned (1:1) to stop treatment or continue maintenance chemotherapy (six cycles of intravenous vinorelbine 25 mg/m2 on days 1, 8, and 15, and daily oral cyclophosphamide 25 mg/m2, on days 1-28). Randomisation was done by use of a web-based system and was stratified (block size of four) by enrolling country and risk subgroup. Neither investigators nor patients were masked to treatment allocation. The primary outcome was disease-free survival in the intention-to-treat population. Secondary outcomes were overall survival and toxicity. This trial is registered with EudraCT, number 2005-000217-35, and ClinicalTrials.gov, number NCT00339118, and follow-up is ongoing. FINDINGS Between April 20, 2006, and Dec 21, 2016, 371 patients were enrolled and randomly assigned to the two groups: 186 to stop treatment and 185 to receive maintenance chemotherapy. Median follow-up was 60·3 months (IQR 32·4-89·4). In the intention-to-treat population, 5-year disease-free survival was 77·6% (95% CI 70·6-83·2) with maintenance chemotherapy versus 69·8% (62·2-76·2) without maintenance chemotherapy (hazard ratio [HR] 0·68 [95% CI 0·45-1·02]; p=0·061), and 5-year overall survival was 86·5% (95% CI 80·2-90·9) with maintenance chemotherapy versus 73·7% (65·8-80·1) without (HR 0·52 [95% CI 0·32-0·86]; p=0·0097). Toxicity was manageable in patients who received maintenance chemotherapy: 136 (75%) of 181 patients had grade 3-4 leucopenia, 148 (82%) had grade 3-4 neutropenia, 19 (10%) had anaemia, two (1%) had thrombocytopenia, and 56 (31%) had an infection. One (1%) patient had a grade 4 non-haematological toxicity (neurotoxicity). Two treatment-related serious adverse events occurred: one case of inappropriate antidiuretic hormone secretion and one of a severe steppage gait with limb pain, both of which resolved. INTERPRETATION Adding maintenance chemotherapy seems to improve survival for patients with high-risk rhabdomyosarcoma. This approach will be the new standard of care for patients with high-risk rhabdomyosarcoma in future EpSSG trials.

Outcome of localized liver-bile duct rhabdomyosarcoma according to local therapy: A report from the European Paediatric Soft-Tissue Sarcoma Study Group (EpSSG)-RMS 2005 study. Pediatr Blood Cancer 2019; 66:e27725.

Abstract
OBJECTIVES To evaluate the impact of local therapies on the outcome of patients with liver-bile duct rhabdomyosarcoma (LBDRMS). METHODS Data of 30 patients included in the EpSSG-RMS 2005 study were analyzed. RESULTS The median age at diagnosis was 3 years (11 months-8 years). All patients had non-alveolar histology. Fifteen patients had a tumor > 5 cm and six had enlarged regional lymph nodes on imaging. Eight patients (27%) had primary surgery (1 R0). Six of them received external beam radiotherapy (EBRT). All are in first complete remission (CR1) except one (R1, EBRT+ , local relapse, death). Six patients (20%) received EBRT without surgery: one had local relapse and died. Sixteen patients (53%) underwent delayed surgery, with 12 achieving R0 margins, which were higher than those in the primary surgery group (P = 0.003). Three patients with R0 margins received EBRT; one had a metastatic relapse and died. Nine patients with R0 resection did not receive EBRT, three relapsed locally (two deaths). Four R1 patients received additional EBRT without relapses. Local relapse occurred in two among 19 patients with EBRT and three among 11 without EBRT (P = 0.326). At a median follow-up of 61 months (48-84 months), five patients died; all had a tumor size > 5 cm (P = 0.01). The five-year overall survival was 85% (95% CI, 65-94), and event-free survival was 76% (95% CI, 54-89). CONCLUSION This analysis did not show any significant difference in outcome between irradiated and nonirradiated patients. Local relapse in LBDRMS is related to initial tumor size and is often fatal.

Impact of 21-Gene Breast Cancer Assay on Treatment Decision for Patients with T1-T3, N0-N1, Estrogen Receptor-Positive/Human Epidermal Growth Receptor 2-Negative Breast Cancer: Final Results of the Prospective Multicenter ROXANE Study. Oncologist 2019; 24:1424-1431.

Abstract
BACKGROUND The ROXANE Italian prospective study evaluated the impact of the 21-gene Recurrence Score (RS) results on adjuvant treatment decision for patients with early breast cancer. MATERIALS AND METHODS Nine centers participated. Physicians used the RS test whenever unsure about adjuvant treatment recommendation for patients with estrogen receptor-positive/human epidermal growth receptor 2-negative, T1-T3, N0-N1 early breast cancer. Pre-RS and post-RS treatment recommendations were collected. RESULTS A total of 251 patients were included. N0 patients (61%) showed higher grade (p < .001) and higher Ki67 (p = .001) and were more frequently progesterone receptor negative (p = .012) as compared with N1 patients. RS results were as follows: <11, n = 63 (25.1%); 11-25, n = 143 (57%); and ≥26, n = 45 (17.9%). Higher RS was found in N0 vs. N1 patients (p = .001) and in cases of G3 (p < .001) and higher Ki67 (p < .001). The rate of change in treatment decision was 30% (n = 75), mostly from chemotherapy (CT) plus hormone therapy (CT + HT) to hormone therapy (HT; 76%, n = 57/75). The proportion of patients recommended to CT + HT was significantly reduced from pre-RS to post-RS (52% to 36%, p < .0001). CT use reduction was more evident for N1 patients (55% to 27%) than for N0 patients (50% to 42%) and was observed only in cases of RS ≤17. CONCLUSION Physicians predominantly used the 21-gene assay in N0 patients with a more aggressive biology or in N1 patients showing more indolent biology. In this selected patient population, the use of RS testing led to a 30% rate of change in treatment decision. In the N1 patient subgroup, the use of RS testing contributed to reduce CT use by more than half. IMPLICATIONS FOR PRACTICE This study shows that, even in a context in which physicians recommend a high proportion of patients to endocrine treatment alone before knowing the results of the Recurrence Score (RS) assay, the use of the RS test, whenever uncertainty regarding adjuvant treatment recommendation is present, significantly contributes in further reducing the use of chemotherapy, especially for N1 patients.

Health-related quality of life (HRQoL) evaluation in the REGOMA trial: A randomized, phase II clinical trial analyzing regorafenib activity in relapsed glioblastoma patients. J Clin Oncol 2019.

Abstract
2045 Background: REGOMA trial showed that regorafenib (REG) significantly improved OS and PFS in relapsed glioblastoma (GBM) patients (pts) with respect to lomustine (LOM). REG showed a different toxicity profile compared to LOM. Here, we report final results of the HRQoL assessment, a secondary end point. Methods: HRQoL was measured using the European Organization for Research and Treatment of Cancer (EORTC) core questionnaire (QLQ-C30) and brain module (QLQ-BN20) administered before any MRI assessments, every 8 weeks (+/- 2 weeks) until disease progression. To evaluate treatment impact on HRQoL, questionnaires at progression were excluded. Mixed-effect linear models were fitted for each of the HRQOL domain to examine the change over progression-free time within and between arms. The models included the time of questionnaire assessment, the treatment group and their interaction, as fixed effects, and a compound symmetry covariance structure for the random effects. Differences of at least 10 points were classified as a clinically meaningful change. To correct for multiple comparisons and to avoid type I error, the level of significance was set at P = 0.01 (2-sided). Results: Of 119 randomized pts, 117 participated in the HRQoL evaluation, and 114 had a baseline assessment (n = 56 REG; n = 58 LOM). No statistically significant differences were observed in any generic or cancer specific domain during treatment in the REG and LOM arms, or between the two arms, except for the appetite loss scale which was significantly worse in PTS treated with REG (Global mean 14.7 (SD = 28.6) vs 7.6 (SD = 16.0); p = 0.0081). The proportion of pts with a clinically meaningful worsening for appetite loss was not statistically different between the two arms (9 out of 24 and 0 out of 13 in the REG and LOM arm, respectively; p = 0.0146). Conclusions: In the REGOMA trial, HRQoL did not change during REG treatment. Pts treated with REG and LOM reported no significant difference in HRQoL. Clinical trial information: NCT02926222.

Clinical features and outcomes of young patients with epithelioid sarcoma: an analysis from the Children's Oncology Group and the European paediatric soft tissue Sarcoma Study Group prospective clinical trials. Eur J Cancer 2019; 112:98-106. [PMID: 30954717 DOI: 10.1016/j.ejca.2019.02.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2018] [Revised: 01/06/2019] [Accepted: 02/02/2019] [Indexed: 10/27/2022]
Abstract
BACKGROUND Data on the clinical features, optimal treatment and outcomes of paediatric patients with epithelioid sarcoma (ES) are limited and mostly retrospective. METHODS A subset analysis of ES patients < 30 years of age enrolled on two international prospective clinical trials conducted between 7/2005 and 11/2015 was performed. Risk-adapted therapy was based on tumour diameter, histologic grade, extent of surgery and presence/absence of metastases and included surgery ± radiotherapy for all patients with the addition of ifosfamide/doxorubicin chemotherapy for intermediate-/high-risk patients. Response to therapy, event-free and overall survival and pattern and predictors of treatment failure were evaluated. RESULTS Sixty-three ES patients (median age 13.1 years, 52% male) were eligible. Clinical features included the following: 68% extremity, median tumour diameter 3.5 cm, 56% high histologic grade, 14% nodal metastases, 14% distant metastases. Thirty-four low-risk patients underwent surgery (n = 30) or surgery/radiotherapy (n = 4); 16 intermediate-risk and 13 high-risk patients received chemotherapy ± surgery ± radiotherapy. Partial response was observed in 11/22 (50%) patients receiving neoadjuvant therapy. Events were local recurrence (n = 10) and distant recurrence (n = 15); estimated 5-year survival was 86.4%, 63.5% and 0%, respectively, for low-, intermediate- and high-risk patients. Locoregional nodal involvement, invasive tumour, high grade and lesser extent of resection predicted event-free survival in patients without metastases. CONCLUSIONS Most low-risk ES patients who have undergone an adequate resection fare well without adjuvant therapy. Large tumour size, high histologic grade, tumour invasiveness, inadequate tumour resection and metastatic disease predict poorer outcomes in higher risk ES patients, for whom more effective therapies are needed.

Self-efficacy for coping: utility of the Cancer behavior inventory (Italian) for use in palliative care. BMC Palliat Care 2019; 18:34. [PMID: 30953485 PMCID: PMC6449975 DOI: 10.1186/s12904-019-0420-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Accepted: 03/27/2019] [Indexed: 11/25/2022] Open
Abstract
Background Newer models of palliative and supportive cancer care view the person as an active agent in managing physical and psychosocial challenges. Therefore, personal efficacy is an integral part of this model. Due to the lack of instruments in Italian to assess coping self-efficacy, the present study included the translation and validation of the Italian version of the Cancer Behavior Inventory–Brief (CBI-B/I) and an initial analysis of the utility of self-efficacy for coping in an Italian sample of palliative care patients. Methods 216 advanced cancer patients who attended palliative care clinics were enrolled. The CBI-B/I was administered along with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), the Mini Mental Adjustment to Cancer Scale (Mini-MAC), the Cancer Concerns Checklist (CCL), and the Hospital Anxiety and Depression Scale (HADS). The Eastern Cooperative Oncology Group Performance Status (ECOG-PS) ratings of functional capacity were completed by physicians. Results Factor analysis confirmed that the structure of the CBI-B/I was consistent with the English version. Internal consistency reliability and significant correlations with the EORTC QLQ-C30, Mini-MAC, and HADS supported the concurrent validity of the CBI-B/I. Differences in CBI-B/I scores for high versus low levels of the CCL and ECOG-PS supported the clinical utility of the CBI-B/I. Conclusions The CBI-B/I has strong psychometric properties and represents an important addition to newer model of palliative and supportive care. In order to improve clinical practice, the CBI-B/I could be useful in identifying specific self-efficacy goals for coping in structured psychosocial interventions.

Abstract
Purpose To evaluate the clinical significance of indeterminate pulmonary nodules at diagnosis (defined as ≤ 4 pulmonary nodules < 5 mm or 1 nodule measuring ≥ 5 and < 10 mm) in patients with pediatric rhabdomyosarcoma (RMS). Patients and Methods We selected patients with supposed nonmetastatic RMS treated in large pediatric oncology centers in the United Kingdom, France, Italy, and the Netherlands, who were enrolled in the European Soft Tissue Sarcoma Study Group (E pSSG) RMS 2005 study. Patients included in the current study received a diagnosis between September 2005 and December 2013, and had chest computed tomography scans available for review that were done at time of diagnosis. Local radiologists were asked to review the chest computed tomography scans for the presence of pulmonary nodules and to record their findings on a standardized case report form. In the E pSSG RMS 2005 Study, patients with indeterminate pulmonary nodules were treated identically to patients without pulmonary nodules, enabling us to compare event-free survival and overall survival between groups by log-rank test. Results In total, 316 patients were included; 67 patients (21.2%) had indeterminate pulmonary nodules on imaging and 249 patients (78.8%) had no pulmonary nodules evident at diagnosis. Median follow-up for survivors (n = 258) was 75.1 months; respective 5-year event-free survival and overall survival rates (95% CI) were 77.0% (64.8% to 85.5%) and 82.0% (69.7% to 89.6%) for patients with indeterminate nodules and 73.2% (67.1% to 78.3%) and 80.8% (75.1% to 85.3%) for patients without nodules at diagnosis ( P = .68 and .76, respectively). Conclusion Our study demonstrated that indeterminate pulmonary nodules at diagnosis do not affect outcome in patients with otherwise localized RMS. There is no need to biopsy or upstage patients with RMS who have indeterminate pulmonary nodules at diagnosis.

Demographic and Treatment Variables Influencing Outcome for Localized Paratesticular Rhabdomyosarcoma: Results From a Pooled Analysis of North American and European Cooperative Groups. J Clin Oncol 2018; 36:JCO2018789388.

Abstract
PURPOSE Treatment recommendations for localized paratesticular rhabdomyosarcoma (PT RMS) differ in North America and Europe. We conducted a pooled analysis to identify demographic features and treatment choices that affect outcome. PATIENTS AND METHODS We retrospectively analyzed the effect of nine demographic variables and four treatment choices on event-free survival (EFS) and overall survival (OS) from 12 studies conducted by five cooperative groups. RESULTS Eight hundred forty-two patients with localized PT RMS who enrolled from 1988 to 2013 were included. Patients age ≥ 10 years were more likely than younger patients to have tumors that were > 5 cm, enlarged nodes (N1), or pathologically involved nodes ( P ≤ .05 each). With a median follow-up of 7.5 years, Kaplan-Meier estimates for 5-year EFS and OS were 87.7% and 94.8%, respectively. Of demographic variables, cooperative group, era of enrollment, age category, tumor size, Intergroup Rhabdomyosarcoma Study group, and T stage affected EFS ( P ≤ .05 each). Surgical assessment of regional nodes, which was performed in 23.5% of patients-usually in those age ≥ 10 years or with suspicious or N1 nodes-was the only treatment variable associated with EFS by univariable and multivariable analyses ( P ≤ .05 each) in patients age ≥ 1 year. A variable selection procedure on a proportional hazards regression model selected era of enrollment, age, tumor size, and surgical assessment of regional nodes as significant ( P ≤ .05 each) in the EFS model, and era of enrollment, age, tumor size, and histology ( P ≤ .05 each) in the OS model. CONCLUSION Localized PT RMS has a favorable prognosis. Age ≥ 10 years at diagnosis and tumor size larger than 5 cm are unfavorable prognostic features. Surgical assessment of regional nodes is important in patients age ≥ 10 years and in those with N1 nodes as it affects EFS.

Addition of dose-intensified doxorubicin to standard chemotherapy for rhabdomyosarcoma (EpSSG RMS 2005): a multicentre, open-label, randomised controlled, phase 3 trial. Lancet Oncol 2018; 19:1061-1071. [PMID: 29941280 DOI: 10.1016/s1470-2045(18)30337-1] [Citation(s) in RCA: 123] [Impact Index Per Article: 20.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2018] [Revised: 04/10/2018] [Accepted: 04/23/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND Rhabdomyosarcoma is an aggressive tumour that can develop in almost any part of the body. Doxorubicin is an effective drug against rhabdomyosarcoma, but its role in combination with an established multidrug regimen remains controversial. Therefore, we aimed to evaluate the possible benefit of early dose intensification with doxorubicin in patients with non-metastatic rhabdomyosarcoma. METHODS We did a multicentre, open-label, randomised controlled, phase 3 trial involving 108 hospitals from 14 countries. We included patients older than 6 months but younger than 21 years with a pathologically proven diagnosis of rhabdomyosarcoma. We assigned each patient to a specific subgroup according to the EpSSG stratification system. Those with embryonal rhabdomyosarcoma incompletely resected and localised at unfavourable sites with or without nodal involvement, or those with alveolar rhabdomyosarcoma without nodal involvement were considered at high risk of relapse. These high-risk patients were randomly assigned (1:1) to receive either nine cycles of IVA (ifosfamide 3 g/m2 given as a 3-h intravenous infusion on days 1 and 2, vincristine 1·5 mg/m2 weekly during the first 7 weeks then only on day 1 of each cycle [given as a single intravenous injection], and dactinomycin 1·5 mg/m2 on day 1 given as a single intravenous injection) or four cycles of IVA with doxorubicin 30 mg/m2 given as a 4-h intravenous infusion on days 1 and 2 followed by five cycles of IVA. The interval between cycles was 3 weeks. Randomisation was done using a web-based system and was stratified (block sizes of four) by enrolling country and risk subgroup. Neither investigators nor patients were masked to treatment allocation. The primary endpoint was 3-year event-free survival assessed by the investigator at each centre in the intention-to-treat population. Patients who received at least one dose of study treatment were considered in the safety analysis. In agreement with the independent data monitoring committee, the study was closed to patient entry on Dec 16, 2013, after futility analysis. This trial is registered with EudraCT, number 2005-000217-35, and is currently in follow-up. FINDINGS Between Oct 1, 2005, and Dec 16, 2013, 484 patients were randomly assigned to receive each chemotherapy regimen (242 in the IVA group and 242 in the IVA plus doxorubicin group). Median follow-up was 63·9 months (IQR 44·6-78·9). The 3-year event-free survival was 67·5% (95% CI 61·2-73·1) in the IVA plus doxorubicin group and 63·3% (56·8-69·0) in the IVA group (hazard ratio 0·87, 95% CI 0·65-1·16; p=0·33). Grade 3-4 leucopenia (232 [93%] of 249 patients in the IVA plus doxorubicin group vs 194 [85%] of 227 in the IVA group; p=0·0061), anaemia (195 [78%] vs 111 [49%]; p<0·0001), thrombocytopenia (168 [67%] vs 59 [26%]; p<0.0001), and gastrointestinal adverse events (78 [31%] vs 19 [8%]; p<0·0001) were significantly more common in the IVA plus doxorubicin group than in the IVA group. Grade 3-5 infections (198 [79%] vs 128 [56%]; p<0·0001) were also significantly more common in the IVA plus doxorubicin group than in the IVA group, in which one patient had grade 5 infection. Two treatment-related deaths were reported (one patient developed septic shock and one affected by Goldenhar syndrome developed intractable seizures) in the IVA plus doxorubicin group, both occurring after the first cycle of treatment, and none were reported in the IVA group. INTERPRETATIONS The addition of dose-intensified doxorubicin to standard IVA chemotherapy did not show a significant improvement in the outcome of patients with high-risk non-metastatic rhabdomyosarcoma. Therefore, the IVA chemotherapy regimen should remain the standard of care for patients with localised rhabdomyosarcoma in Europe.

Abstract
LBA2 Background: Most patients with localized RMS achieve complete remission during standard (std) treatment but approximately 20-30% of them relapse and chance of salvage is poor. We tested whether adding maintenance metronomic chemotherapy after std chemotherapy would improve survival for patients with non metastatic RMS defined as HR according to EpSSG stratification. Methods: Patients (pts) age >6 months <21 years, with N0 alveolar (A)RMS or incompletely resected (Group II or III) embryonal (E)RMS arising in an unfavorable primary site and/or N1 in complete remission after std treatment including 9 cycles of ifosfamide, vincristine and actinomycin D +/- doxorubicin, surgery and/or radiotherapy were eligible for randomization to stop treatment (Std-arm) or receive maintenance chemotherapy (M-arm) with 6 28-day cycles of iv vinorelbine 25 mg/m2 on day 1,8,15 of each cycle and continuous daily oral cyclophosphamide 25 mg/m2 . The study was initially designed with 80% power (5% 2-sided alpha level) to detect an increase in 3 yr Event Free Survival (EFS) from 55% to 67%, a Hazard Ratio of 0.67, but was successively amended to allow a detection of a relative reduction in the relapse rate of 50% in the M-arm, with 80% power, testing at the 5% significance level (2-sided). Results: 670 pts were entered between 4/2006-12/2016, with 371 confirmed eligible and 186 assigned to the std-arm and 185 to M-arm. Clinical features were well balanced in the two arms and included ERMS 67%, ARMS 33%, age 10+ years 21%; IRS Group III 86%; N1 16%. Most common primary tumor sites were parameningeal (32%) and “other” sites (23%). With median follow up of 5 years in surviving pts, 3 yr EFS and overall survival (OS) in M-arm vs Std-arm were respectively: EFS 78.4% (95% IC -71.5-83.8) vs 72.3% (95% IC -65.0-78.3) (p 0.061) and OS 87.3% (95% IC 81.2-91.6) vs 77.4 (95% IC 70.1-83.1) (p = 0.011). Toxicity in the M-arm was manageable: grade 3/4 febrile neutropenia in 25% of pts, grade 4 neurotoxicity in 1.1%. Conclusions: The addition of maintenance after std treatment significantly improves OS in HR RMS patients and support its inclusion in future EpSSG trials. Clinical trial information: 2005-000217-35.

Abstract
INTRODUCTION Cutaneous melanoma is rare in childhood and published studies have mainly been retrospective single-institution series or small case series. Given the absence of clinical protocols dedicated to pediatric melanoma, the treatment approach is generally extrapolated from the ones applied to adults. METHODS Coordinated by the European Cooperative Study Group for Pediatric Rare Tumors (EXPeRT), this study collected patients prospectively registered between 2002 and 2012 under national cooperative projects dedicated to rare pediatric tumors in Italy, Poland, Germany, and France. Additional cases were collected from dermatology registries in Germany and Israel. RESULTS A total of 219 patients aged 0-18 years (median 14.4) were included in the analysis. Sentinel lymph node biopsy was performed in 112 patients (76% of those with Breslow thickness > 0.75 mm) and was positive in 37.5%. Systemic therapy was used in 33 cases. In stage III cases, survival rates were similar for patients who received (23 cases) or not (21 cases) adjuvant therapy. For the whole series, 3-year overall and disease-free survival rates were 91.4% and 84.0%, respectively (median follow-up 41.8 months). Tumor site, tumor stage, and ulceration influenced survival rates. Patients treated by pediatric oncologists (n = 140) were more likely to have advanced disease than those treated by dermatologists (n = 79). DISCUSSION This study would suggest that the clinical history of melanoma in children and adolescents might resemble that of adult counterpart. Cooperative efforts are needed to make new drugs more readily available to pediatric patients to increase the outcome of patient with advanced disease.

Abstract
BACKGROUND As alveolar soft part sarcomas (ASPS) are rare with no prospective series within pediatric sarcoma trials, the European Paediatric Soft Tissue Sarcoma Study Group (EpSSG) examined the clinical data and outcomes of ASPS enrolled in a multinational study of nonrhabdomyosarcoma soft tissue sarcomas (NRSTS). PATIENTS AND METHODS Twenty-two patients with ASPS were enrolled into the EpSSG NRSTS 2005 study. After surgical resection, subsequent treatment depended on the stratification of patients for completeness of resection and Intergroup Rhabdomyosarcoma Study (IRS) stage, size, and French Federation of Cancer Centres Sarcoma Group (FNCLCC) grade. Chemotherapy using ifosfamide and doxorubicin was performed in IRS group III. Radiotherapy was performed in IRS groups II and III, and FNCLCC grades 2 and 3 tumors. RESULTS The median age at diagnosis was 11.5 years (range 2.7-17.5 years). The majority in the series had localized disease (20), with small IRS I tumors (12), and in total 19 had surgical resection upfront. Of the four patients who received conventional chemotherapy, there were no responses. Three of 20 patients with localized tumors and all metastatic patients developed metastases. The median follow up of patients with localized disease is 61.7 months (range 25.7-135.5 months) from diagnosis. The 5-year event-free survival is 94.7% (95% confidence interval: 68.1-99.2), and therefore the overall survival (OS) is 100%. CONCLUSION This report demonstrates the ability to run prospective pediatric studies in NRSTS in multiple European countries, despite the small numbers of ASPS patients. We can conclude that for the majority with small resected tumors, there were few events and no deaths.

Abstract
A genomic index (GI) tool using array comparative genomic hybridization (aCGH) on tumor cells has emerged as independent prognostic factor associated with the risk of metastatic relapse in synovial sarcoma (SS). The aim was to assess GI in pediatric patients with SS, to determine its value as a prognostic factor. All pediatric/adolescent/young adults' (<25 years) with localized SS prospectively included in the European EpSSG-NRSTS05 protocol with a contributive aCGH were selected. Definition of GI was A2 /C, where A is the total number of alterations (segmental gains and losses) and C is the number of involved chromosomes on aCGH results. GI1 group corresponds to cases with no copy number alterations (flat profile, GI = 0) and GI2 group cases with at least one or more copy number alterations (rearranged profile; GI ≥ 1). Samples were available from 61 patients. The median age of the cohort was 13 years (range: 4-24). Overall, 55.7% were GI1 group, and 44.3% GI2 . After a median follow-up of 62 months (range: 0.1-112), 10 tumor events occurred and five patients died. Respectively, for GI1 versus GI2 groups, five-year event-free survival (EFS) was 93.8 ± 4.2% versus 64.9 ± 10.1% (P < 0.006) and five-year Metastatic-Free Survival (MFS) 93.8 ± 4.2% versus 72.9 ± 9.5% (P < 0.04). In multivariate analysis, GI status as adjusted for IRS group, patient age, site, and tumor size remain independent prognostic for EFS with a relative risk (RR) of 6.4 [1.3-31.9] (P < 0.01) and RR for MFS is 4.8 [0.9-25.7] (P < 0.05). Genomic complexity evaluated through GI may explain the metastatic behavior of pediatric SS.

Resistance to glucose starvation as metabolic trait of platinum-resistant human epithelial ovarian cancer cells. Oncotarget 2018; 8:6433-6445.

Abstract
Deregulated glucose metabolism is observed in cancer but whether this metabolic trait influences response to or is modulated by cytotoxic drugs is unknown. We show here that tumor cells from epithelial ovarian cancer (EOC) patients can be categorized, according to their in vitro viability under glucose starvation, into glucose deprivation-sensitive (glucose-addicted, GA) and glucose deprivation-resistant (glucose non-addicted, GNA). When EOC cells were cultured in the absence of glucose, all samples from platinum (PLT)-sensitive patients felt into the GA group; they disclosed higher expression of glucose metabolism enzymes, higher proliferation rates and in vitro sensitivity to PLT. Moreover, GA patients showed reduced multi-drug resistance pump expression and autophagy, compared to GNA samples. The close association between PLT sensitivity and glucose metabolic profile was confirmed in a xenograft model, where a stringent parallelism between PLT sensitivity/resistance and glucose metabolism was identified. Finally, in a cohort of naïve EOC patients categorized as GA or GNA at diagnosis, Kaplan Meier curves showed that the GA phenotype was associated with significantly better progression-free survival, compared to GNA patients.

First Prospective Multicenter Italian Study on the Impact of the 21-Gene Recurrence Score in Adjuvant Clinical Decisions for Patients with ER Positive/HER2 Negative Breast Cancer. Oncologist 2017; 23:297-305.

Abstract
BACKGROUND The Breast DX Italy prospective study evaluated the impact of the 21-gene recurrence score (RS) result on adjuvant treatment decisions for patients with early breast cancer. MATERIALS AND METHODS Nine centers (two Hub and seven Spoke centers of the Veneto Oncology Network) participated. Consecutive patients with estrogen receptor positive, human epidermal growth receptor negative, T1-T3, N0-N1 early breast cancer were prospectively registered; only those meeting protocol-defined clinicopathological "intermediate risk" criteria were eligible for the RS test. Pre-RS and post-RS physicians' treatment recommendations and treatment actually received were collected. RESULTS A total of n = 124 N0 and n = 126 N1 patients underwent the RS assay. The majority had Grade 2 tumors (71%); median age was 55 years, median tumor size was 16 mm, and median Ki67 expression was 20%. Patients enrolled at Hub centers presented higher-risk features. The distribution of RS results was <18 (60.8%), 18-30 (32.4%), and >30 (6.8%). The indication before RS was hormonal therapy (HT) alone in 52% of cases. An indication before RS of chemotherapy (CT)+HT was more frequent for patients with N1 versus N0 tumors (57% vs. 39%, p = .0035) and for patients enrolled at Hub versus Spoke centers (54% vs. 36%, p = .007).The overall rate of change in treatment decision was 16% (n = 40), mostly from CT+HT to HT (n = 30). According to nodal status, rate of change in treatment decision was 12% for the N0 cohort and 20% for the N1 cohort. The proportion of patients recommended to CT+HT was significantly reduced from before to after RS (48% to 40%, p < .0016), especially in the N1 cohort (57% to 45%, p = .0027) and at Hub centers (54% to 44%, p = .001). CONCLUSION Despite frequent indication of HT before RS, the use of the RS assay further contributed to sparing CT, especially for patients with N1 tumors and at Hub centers. IMPLICATIONS FOR PRACTICE This study shows that, although a high proportion of patients were recommended to receive endocrine treatment alone before knowing the recurrence score (RS) assay, the RS test further contributed in sparing chemotherapy for some of these patients, especially in case of the N1 stage or for patients enrolled at referral centers. These data highlight the need for further work in collaboration with health authorities and companies in order to define strategies for the implementation of the use of RS testing in clinical practice in the Italian setting.

A European randomised controlled trial of the addition of etoposide to standard vincristine and carboplatin induction as part of an 18-month treatment programme for childhood (≤16 years) low grade glioma - A final report. Eur J Cancer 2017; 81:206-225. [PMID: 28649001 PMCID: PMC5517338 DOI: 10.1016/j.ejca.2017.04.019] [Citation(s) in RCA: 85] [Impact Index Per Article: 12.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2016] [Revised: 03/23/2017] [Accepted: 04/18/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND The use of chemotherapy to manage newly diagnosed low grade glioma (LGG) was first introduced in the 1980s. One randomised trial has studied two- versus four-drug regimens with a duration of 12 months of treatment after resection. METHODS Within the European comprehensive treatment strategy for childhood LGG, the International Society of Paediatric Oncology-Low Grade Glioma (SIOP LGG) Committee launched a randomised trial involving 118 institutions and 11 countries to investigate the addition of etoposide (100 mg/m2, days 1, 2 & 3) to a four-course induction of vincristine (1.5 mg/m2 × 10 wkly) and carboplatin (550 mg/m2 q 3 weekly) as part of 18-month continuing treatment programme. Patients were recruited after imaging diagnosis, resection or biopsy with progressive disease/symptoms. Some 497 newly diagnosed patients (M/F 231/266; median age 4.26 years (interquartile range (IQR) 2.02-7.06)) were randomised to receive vincristine carboplatin (VC) (n = 249) or VC plus etoposide (VCE) during induction (n = 248), stratified by age and tumour site. FINDINGS No differences between the two arms were found in term of survival and radiological response. Response and non-progression rates at 24 weeks for VC and VCE, were 46% versus 41%, and 93% versus 91% respectively; 5-year Progression-Free Survival (PFS) and Overall Survival (OS) were 46% (StDev 3.5) versus 45% (StDev 3.5) and 89% (StDev 2.1) versus 89% (StDev 2.1) respectively. Age and diencephalic syndrome are adverse clinical risk factors for PFS and OS. 5-year OS for patients in early progression at week 24 were 46% (StDev 13.8) and 49% (StDev 16.5) in the two arms, respectively. INTERPRETATION The addition of etoposide to VC did not improve PFS or OS. High non-progression rates at 24 weeks justify retaining VC as standard first-line therapy. Infants with diencephalic syndrome and early progression need new treatments to be tested. Future trials should use neurological/visual and toxicity outcomes and be designed to discriminate between the impact on disease outcomes of 'duration of therapy' and 'age at stopping therapy'.

Access to clinical trials for adolescents with soft tissue sarcomas: Enrollment in European pediatric Soft tissue sarcoma Study Group (EpSSG) protocols. Pediatr Blood Cancer 2017; 64. [PMID: 27882658 DOI: 10.1002/pbc.26348] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2016] [Revised: 09/28/2016] [Accepted: 10/12/2016] [Indexed: 02/04/2023]
Abstract
BACKGROUND Adolescents with cancer are enrolled in clinical trials at far lower rates than children. This report compares the number of adolescents (15-19-year-olds) and children (0-14-year-olds) enrolled in the protocols of the European pediatric Soft tissue sarcoma Study Group (EpSSG) with the number of cases expected to occur. METHODS The observed-to-expected (O/E) ratio was detected in the EpSSG countries contributing most of the cases, that is, Italy, France, Spain, the Netherlands, United Kingdom, and Ireland. The observed cases included patients enrolled in any of the EpSSG protocols from October 2008 to October 2015, when all EpSSG protocols were open in these countries. The number of expected cases was calculated from the incidence rates estimated throughout the RARECAREnet database in the countries' population-based cancer registries. RESULTS In the countries considered, 2,118 cases aged 0-19 years were enrolled in the EpSSG trials from 2008 to 2015: 82.8% were children and 17.2% were adolescents. The O/E ratio was 0.30 among patients 15-19 years old, as opposed to 0.64 for those 0-14 years old. The O/E ratio differed for the different subtypes: in adolescents, it was 0.64 and 0.18 for rhabdomyosarcoma (RMS) and non-rhabdomyosarcoma soft tissue sarcomas (NRSTS), respectively; in children, it was 0.77 and 0.50, respectively. The O/E ratios differed across the countries considered. CONCLUSIONS Adolescents were less well represented than children on the EpSSG protocols, with better enrolment for RMS than for NRSTS for all age groups.

First prospective multicenter Italian study on the impact of the 21-Gene Recurrence Score (RS) in adjuvant clinical decisions for ER+/HER2- early breast cancer (BC) patients. J Clin Oncol 2017.

Abstract
e12038 Background: The Breast-DX Italy prospective study evaluated the impact of the 21-gene RS on adjuvant treatment decisions for early BC patients. Methods: The study was conducted in 9 centers of the Veneto Region (2 hub and 7 spoke). All consecutive patients with ER+/HER2-, T1 to T3, N0 to N1 early BC who met protocol-defined clinicopathological criteria for “intermediate risk” were included. Pre-RS and post-RS physicians’ treatment recommendations and treatment actually received were collected. Results: From November 2014 to August 2016, n=124 N0 and n=126 N1 patients were enrolled (65% at hub and 35% at spoke centers). The majority had PgR+ (86%), G2 (71%) and pT1c (63%) BC. Median age was 55 yrs, median Ki67 was 20% (range 2-70%). The distribution of RS was: <18 (61%), 18-30 (32%) and >30 (7%). Main factors associated with higher RS were G3 and higher ki67. The addition of chemotherapy (CT) to hormonal therapy (HT) was initially recommended for 48% of the patients (38% of N0 and 57% of N1 patients; 54% and 37% of patients enrolled at hub and spoke centers, respectively). The post-RS recommendation changed from the pre-RS recommendation for 40 patients, mostly from CT+HT to HT (n=30; n=25 with low and n=5 with intermediate RS). Change was more frequent for N1 patients (Table). Of the 72 N1 patients initially recommended to CT+HT, 28% had a post-RS indication to HT alone. The crude number of patients with pre-RS recommendation to CT significantly exceeded the number of patients who finally received it (absolute difference =31; p<0.001). The majority of CT treatments were spared at hub vs spoke centers (n=24 and n=7, respectively). Conclusions: Pre-RS indication to HT alone was frequent, in particular for N0 patients and at spoke centers. The use of the 21-gene RS further contributed in sparing CT administration, more so for N1 patients and at hub centers. The impact of the RS when used at discretion of the clinicians is currently under investigation in the prospective ROXANE study. [Table: see text]

REGOMA: A randomized, multicenter, controlled open-label phase II clinical trial evaluating regorafenib (REG) activity in relapsed glioblastoma (GBM) patients (PTS). J Clin Oncol 2017.

Abstract
TPS2085 Background: GBM is the most common and malignant form of primary brain tumor with a high recurrence rate after surgery, radiation therapy and temozolomide. Currently, there is no established regimen for the treatment of recurrent GBM. GBMs are highly vascularized tumors with high expression of pro-angiogenic factors and activation of multiple signaling pathways in the tumor microenvironment, including the receptor tyrosine kinases, VEGFR, FGFR, and PDGFR, which control the tumor vasculature. REG, an oral multikinase inhibitor, inhibits these angiogenic kinases and the mutant oncogenic kinases KIT, RET and B-RAF. REG was demonstrated to be safe and effective in metastatic colon-rectal cancer, hepatocellular carcinoma and GIST PTS. It was shown that REG inhibits tumor angiogenesis and tumor cell proliferation in rat GBM tumor xenografts (Wilhelm S.M, et al. Regorafenib: a new oral multikinase inhibitor of angiogenic, stromal and oncogenic receptor tyrosine kinases with potent preclinical antitumor activity. Int. J. Cancer:129,245-255.2011). Methods: Primary aim of the study is to assess the role of REG activity in prolonging the overall survival in relapsed GBM PTS after surgery and Stupp regimen; secondary aims are to analyze progression free survival, objective response rate, disease control rate and quality of life. Eligible PTS with ECOG PS 0-1, documented progression of disease (after Stupp treatment) as defined by RANO criteria, adequate bone marrow, liver and renal function are randomized in a 1:1 ratio to REG 160 mg/die (3 weeks on, 1 week off) or lomustine 110 mg/m2 (every 6 weeks). A total of 112 PTS will be randomized (α = 0.20, β = 0.20) and stratified based on surgery at recurrence. Disease evaluation is performed with gadolinium brain MRI every 8 weeks according to RANO criteria. Additional exploratory objectives include analysis of specific angiogenic and metabolic biomarkers in tissue as possible predictors of response to REG. The trial started in Nov 2015; as of Jan 2017, 105 PTS have been enrolled. Final analysis is planned in Dec 2017. Clinical trial information: NCT02926222.
