Intermediate-risk endometrial cancer treated with adjuvant brachytherapy using single dosimetric planning: long-term outcome and toxicity assessment. Eur J Obstet Gynecol Reprod Biol 2024; 298:23-30. [PMID: 38705010 DOI: 10.1016/j.ejogrb.2024.04.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 03/22/2024] [Accepted: 04/29/2024] [Indexed: 05/07/2024]
Abstract
OBJECTIVE Brachytherapy of the vaginal dome is the recommended adjuvant treatment for intermediate-risk endometrial cancer. This study assessed the results of dosimetric planning of high-dose-rate brachytherapy exclusively in the first treatment session. STUDY DESIGN This retrospective study included all patients who underwent hysterectomy for endometrial cancer followed by adjuvant brachytherapy of the vaginal dome between 2012 and 2015. Local recurrence rates, overall survival (OS) rates, recurrence-free survival (RFS) rates, and related acute and late toxicity rates were evaluated. RESULTS This analysis included 250 patients, of whom 208 were considered to be at high-intermediate risk of disease recurrence. After a median follow-up of 56 months, the cumulative incidence of local recurrence was 4.8% at 3 years [95% confidence interval (CI) 2.8-8.3] and 7.8% at 5 years (95% CI 4.8-12.6). The 5-year OS rate was 86.2% (95% CI 80.6-90.3), and the 5-year RFS rate was 77.5% (95% CI 71.1-82.7). Acute toxicity occurred in 20 (8%) patients, of which two patients had grade ≥3 toxicity. Only one patient (0.4%) presented with late grade ≥3 toxicity. CONCLUSION These findings confirm the tolerability of this brachytherapy approach, indicating minimal cases of late grade ≥3 toxicity, associated with a good 5-year OS rate. With the advent of molecular prognostic factors, the current focus revolves around discerning those individuals who gain the greatest benefit from adjuvant therapy, and tailoring treatment more effectively.

Long term activity of vemurafenib in cancers with BRAF mutations: the ACSE basket study for advanced cancers other than BRAF V600-mutated melanoma. ESMO Open 2023; 8:102038. [PMID: 37922690 PMCID: PMC10774964 DOI: 10.1016/j.esmoop.2023.102038] [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: 08/09/2023] [Revised: 09/14/2023] [Accepted: 09/21/2023] [Indexed: 11/07/2023] Open
Abstract
BACKGROUND BRAF inhibitors are approved in BRAFV600-mutated metastatic melanoma, non-small-cell lung cancer (NSCLC), Erdheim-Chester disease (ECD), and thyroid cancer. We report here the efficacy, safety, and long-term results of single-agent vemurafenib given in the AcSé vemurafenib basket study to patients with various BRAF-mutated advanced tumours other than BRAFV600-mutated melanoma and NSCLC. PATIENTS AND METHODS Patients with advanced tumours other than BRAFV600E melanoma and progressing after standard treatment were eligible for inclusion in nine cohorts (including a miscellaneous cohort) and received oral vemurafenib 960 mg two times daily. The primary endpoint was the objective response rate (ORR) estimated with a Bayesian design. The secondary outcomes were disease control rate, duration of response, progression-free survival (PFS), overall survival (OS), and vemurafenib safety. RESULTS A total of 98 advanced patients with various solid or haematological cancers, 88 with BRAFV600 mutations and 10 with BRAFnonV600 mutations, were included. The median follow-up duration was 47.7 months. The Bayesian estimate of ORR was 89.7% in hairy cell leukaemias (HCLs), 33.3% in the glioblastomas cohort, 18.2% in cholangiocarcinomas, 80.0% in ECD, 50.0% in ovarian cancers, 50.0% in xanthoastrocytomas, 66.7% in gangliogliomas, and 60.0% in sarcomas. The median PFS of the whole series was 8.8 months. The 12-, 24-, and 36-month PFS rates were 42.2%, 23.8%, and 17.9%, respectively. Overall, 54 patients died with a median OS of 25.9 months, with a projected 4-year OS of 40%. Adverse events were similar to those previously reported with vemurafenib. CONCLUSION Responses and prolonged PFS were observed in many tumours with BRAF mutations, including HCL, ECD, ovarian carcinoma, gliomas, ganglioglioma, and sarcomas. Although not all cancer types responded, vemurafenib is an agnostic oncogene therapy of cancers.

Abstract
BACKGROUND Stabilization or spontaneous regressions are demonstrated in more than half of patients affected by primary desmoid-type fibromatosis (DF) in retrospective studies. The objective of this phase II study was to prospectively assess the behavior of primary sporadic DT managed by active surveillance (AS). METHODS This prospective, multicenter, observational study (NCT01801176) included patients ≥18 years of age with primary sporadic DF located in an extremity or the abdominal/thoracic wall. At inclusion, all patients were initially placed on AS. Follow-up was based on clinical and radiological evaluation by magnetic resonance imaging (MRI) performed at 1, 3, 6, 9, and 12 months, and then every 6 months for 3 years. The primary endpoint was progression-free survival (PFS) at 3 years according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, as evaluated by a Central Review Board. RESULTS Between 2012 and 2015, 100 patients were enrolled. The female/male ratio was 8 and the median age was 34 years (interquartile range [IQR] 30.8-43.9). Median follow-up was 46.6 months (IQR 36.8-61.1) and the 3-year PFS was 53.4% (95% confidence interval 43.5-63.1%). At progression (48 patients), 23 patients received active treatment. Fifty-eight patients (58%) presented with spontaneous tumor regression (decrease > 0% compared with the initial size) during the first 3 months (n = 35, 35%) or after an initial progression (n = 23, 23%), of whom 26 (26%) had partial responses (PRs). The median time to PR was 31.7 months (25.3-not available). CONCLUSIONS These data support the use of AS as the primary approach to select patients with peripheral DF who require aggressive treatment.

[Contribution of whole-body MRI to the initial assessment of myxoid liposarcoma]. Bull Cancer 2023; 110:1015-1026.

Abstract
INTRODUCTION Myxoid liposarcoma is a soft tissue sarcoma associated with multifocal metastases at diagnosis. These metastases are asymptomatic and occult on CT and FDG-PET and can alter the therapeutic management and prognosis. In this context, we evaluated the contribution of whole-body MRI to the initial workup of patients with myxoid liposarcoma. METHOD This retrospective study was conducted between January 2015 and December 2020 at the Oscar Lambret Center. We enrolled 22 patients who were diagnosed with myxoid liposarcoma and underwent whole-body MRI at diagnosis. The number of metastases at diagnosis, their location, and the visibility of these lesions on CT were evaluated. Associations between clinical features, presence of metastasis, and their impact on management were assessed. RESULTS Sixteen patients (72.7%) had non-metastatic disease at the initial diagnosis, and 15 of these patients were managed using local treatment. Six patients (27.3%) had metastases at multiple locations and received chemotherapy. The main locations were the bones (n=5) and lungs (n=3). In five patients with metastases, whole-body MRI demonstrated additional lesions that were not visible on CT (bone and soft tissue lesions). Only the presence of a round cell contingent (P=0.009) was found as a criterion associated with the presence of metastases. CONCLUSION The patients' young age, absence of reliable prognostic factors at diagnosis, asymptomatic nature of the lesions, and the benefits of early and targeted therapeutic management encourage the use of whole-body MRI as part of the initial work-up as it seems to provide a better initial staging compared with conventional imaging.

Abstract
Uterine adenosarcoma is a very rare malignancy defined as a biphasic tumor composed of both benign epithelial component and a malignant sarcoma component. The stage of the disease is determined by the presence of myometrial invasion and the extent of extra-uterine disease. The most important histopronostic factors are the existence of a sarcomatous overgrowth defined by a sarcomatous contingent occupying more than 25 % of the volume of the tumor (directly correlated to the grade of the disease), the presence of a heterologous and/or a high-grade component. Stage I adenosarcomas without sarcomatous overgrowth have a good prognosis, with an overall 5-year survival of up to 80 %. In localized disease, complete surgical removal is recommended. The role of hormone therapy, chemotherapy and adjuvant radiotherapy is not established. If possible, relapses should be re-treated surgically, with the aim of achieving complete resection. In the advanced inoperable or metastatic setting, hormone therapy is an option for low-grade adenosarcomas with estrogen receptor (ER) and progesterone receptor (PR) overexpression. For high-grade tumors, the standard chemotherapies are doxorubicin-based combinations, although an integrated approach of surgery and medical treatment should also be considered in this setting.

Diagnostic Value of the Texture Analysis Parameters of Retroperitoneal Residual Masses on Computed Tomographic Scan after Chemotherapy in Non-Seminomatous Germ Cell Tumors. Cancers (Basel) 2023; 15:cancers15112997. [PMID: 37296963 DOI: 10.3390/cancers15112997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 05/25/2023] [Accepted: 05/29/2023] [Indexed: 06/12/2023] Open
Abstract
After chemotherapy, patients with non-seminomatous germ cell tumors (NSGCTs) with residual masses >1 cm on computed tomography (CT) undergo surgery. However, in approximately 50% of cases, these masses only consist of necrosis/fibrosis. We aimed to develop a radiomics score to predict the malignant character of residual masses to avoid surgical overtreatment. Patients with NSGCTs who underwent surgery for residual masses between September 2007 and July 2020 were retrospectively identified from a unicenter database. Residual masses were delineated on post-chemotherapy contrast-enhanced CT scans. Tumor textures were obtained using the free software LifeX. We constructed a radiomics score using a penalized logistic regression model in a training dataset, and evaluated its performance on a test dataset. We included 76 patients, with 149 residual masses; 97 masses were malignant (65%). In the training dataset (n = 99 residual masses), the best model (ELASTIC-NET) led to a radiomics score based on eight texture features. In the test dataset, the area under the curve (AUC), sensibility, and specificity of this model were respectively estimated at 0.82 (95%CI, 0.69-0.95), 90.6% (75.0-98.0), and 61.1% (35.7-82.7). Our radiomics score may help in the prediction of the malignant nature of residual post-chemotherapy masses in NSGCTs before surgery, and thus limit overtreatment. However, these results are insufficient to simply select patients for surgery.

Abstract
High-grade endometrial stromal sarcoma (HGESS) and uterine undifferentiated sarcoma (UUS) are rare uterine malignancies arising from mesenchymal endometrial cells. They are characterized by aggressive behavior and poor prognosis. Median age of diagnostic is 55years. The most common symptoms are vaginal bleeding, abdominal pain, and pelvic mass. Approximately 65 % are diagnosed witch advance disease stage III or IV according to the International Federation of Gynecology and Obstetrics classification. Median overall survival is around 20months. The management of the disease must be discussed in multidisciplinary staff meetings. The standard management of HGESS and UUS is total hysterectomy with bilateral oophorectomy. Systematic lymphadenectomy is not recommended. Adjuvant therapies, such as chemotherapy and radiotherapy must be discussed. In case of oligo-metastasic disease, surgery of the primary tumor and metastasis must be discussed and if not operable the standard management is doxorubine-based chemotherapy.

Results of a 20 Year Retrospective Analysis of Early-Stage Cervical Cancer: Should 3 cm Be Considered the New Ariadne's Thread in Early Cervical Cancer Treatment? Cancers (Basel) 2023; 15:cancers15051570. [PMID: 36900360 PMCID: PMC10001182 DOI: 10.3390/cancers15051570] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 02/23/2023] [Accepted: 02/27/2023] [Indexed: 03/06/2023] Open
Abstract
(1) This study aims to evaluate the overall survival (OS) and recurrence-free survivals (RFS) and assess disease recurrence of early-stage cervical cancer (ESCC) patients treated with minimally invasive surgery (MIS). (2) This single-center retrospective analysis was performed between January 1999 and December 2018, including all patients managed with MIS for ESCC. (3) All 239 patients included in the study underwent pelvic lymphadenectomy followed by radical hysterectomy without the use of an intrauterine manipulator. Preoperative brachytherapy was performed in 125 patients with tumors measuring 2 to 4 cm. The 5-year OS and RFS rates were 92% and 86.9%, respectively. Multivariate analysis found two significant factors associated with recurrence: previous conization with HR = 0.21, p = 0.01, and tumor size > 3 cm with HR = 2.26, p = 0.031. Out of the 33 cases of disease recurrence, we witnessed 22 disease-related deaths. Recurrence rates were 7.5%, 12.9%, and 24.1% for tumors measuring ≤ 2 cm, 2 to 3 cm, and > 3 cm, respectively. Tumors ≤ 2 cm were mostly associated with local recurrences. Tumors > 2 cm were frequently associated with common iliac or presacral lymph node recurrences. (4) MIS may still be considered for tumors ≤ 2 cm subject to first conization followed by surgery with the Schautheim procedure and extended pelvic lymphadenectomy. Due to the increased rate of recurrence, a more aggressive approach might be considered for tumors > 3 cm.

Abstract
Low-grade endometrial stromal sarcoma (LG-ESS) accounts for approximately 15% of all uterine sarcomas. Median age of patients is around 50 years and half of the patients are premenopausal. In all, 60% of cases present with FIGO stage I disease. Preoperatively radiologic findings of ESS are not specific. Pathological diagnosis remains essential. This review aimed to present the French guidelines for low grade ESS treatment within the Groupe sarcome français - Groupe d'étude des tumeurs osseuse (GSF-GETO)/NETSARC+ and tumeur maligne rare gynécologique (TMRG) networks. Treatments should be validated in multidisciplinary team involved in sarcomas or rare gynecologic tumors. Hysterectomy is the cornerstone of treatment for localized ESS, and morcellation should be avoided. Systematic lymphadenectomy in ESS does not improve the outcome and is not recommended. Leaving the ovaries in situ in stage I tumors could be discussed for young women. Adjuvant hormonal treatment could be considered, for two years for stage I with morcellation or stage II and livelong for stages III or IV. Nevertheless, several questions remain, such as optimal doses, regimens (progestins or aromatase inhibitors) and duration of therapy. Tamoxifen is contraindicated. Secondary cytoreductive surgery if feasible for recurrent disease, appears to be an acceptable approach. Systemic treatment for recurrent or metastatic disease is mainly hormonal, with or without surgery.

Abstract
Uterine leiomyosarcomas represent the most common uterine sarcomas. The prognosis is poor with metastatic recurrence in more than half of the cases. The purpose of this review is to make French recommendations for the management of uterine leiomyosarcomas within the framework of the French Sarcoma Group - Bone Tumor Study Group (GSF-GETO)/NETSARC+ and Malignant Rare Gynecological Tumors (TMRG) networks in order to optimize their therapeutic management. The initial assessment includes a MRI with diffusion perfusion sequence. The diagnosis is histological with a review in an expert center (Reference Network in Sarcoma Pathology (RRePS)). Total hysterectomy with bilateral salpingectomy, en bloc without morcellation, is performed when complete resection is possible, whatever the stage. There is no indication of systematic lymph node dissection. Bilateral oophorectomy is indicated in peri-menopausal or menopausal women. Adjuvant external radiotherapy is not a standard. Adjuvant chemotherapy is not a standard. It can be an option and consists in doxorobucin based protocols. In the event of local recurrence, the therapeutic options are based on revision surgery and/or radiotherapy. Systemic treatment with chemotherapy is most often indicated. In case of metastatic disease, surgical treatment remains indicated when resecable. In cases of oligo-metastatic disease, focal treatment of metastases should be considered. In the case of stage IV, chemotherapy is indicated, and is based on first-line doxorubicin-based protocols. In the event of excessive deterioration in general condition, management by exclusive supportive care is recommended. External palliative radiotherapy can be proposed for symptomatic purposes.

Abstract
OBJECTIVE Pelvic magnetic resonance imaging (MRI) is a key exam used for the initial assessment of loco-regional involvement of cervical cancer. In patients with locally advanced cervical cancer, MRI is used to evaluate the early response to radiochemotherapy before image-guided brachytherapy, the prognostic impact of which we aimed to study. METHODS Patients with locally advanced cervical cancer treated using concomitant radiochemotherapy followed by closure treatment between January 2010 and December 2015 were included in this study. Clinical, anatomopathological, radiological, therapeutic, and follow-up data were evaluated. RESULTS After applying the inclusion and exclusion criteria to the initially chosen 310 patients, 232 were included for evaluation (median follow-up period, 5.3 years). The median age was 50 years (range, 25-83 years), and the median tumor size was 47.5 mm (range, 0-105 mm). Based on the International Federation of Gynaecology and Obstetrics classification system, 9 patients were in stage IB2; 20, IB3; 2, IIA; 63, IIB; 4, IIIA; 7, IIIB; and 127, IIIC1 or higher. The re-evaluation MRI was performed at the median dose of 55.5 Gy, and median reduction in tumor size was 55.2% (range, -20-100%). There was a difference between the disease-free and overall survival rates of the patients with a tumor response greater or lesser than 50%. The risk of recurrence or death reduced by 39% in patients with a tumor size reduction >50%. The overall 5-year survival rate of patients with a response greater and lesser than 50% were 77.7% and 61.5%, respectively. The 5-year disease-free survival rate for these two groups of patients were 68.8% and 51.5%, respectively. CONCLUSION Our study confirms the prognostic impact of tumor size reduction using MRI data obtained after radiochemotherapy in patients with locally advanced cervical cancer.

Abstract
OBJECTIVE The standard of care for early cervical cancer is radical hysterectomy; however, consideration of pre-operative brachytherapy has been explored. We report our experience using pre-operative brachytherapy plus Wertheim-type hysterectomy to treat early stage cervical cancer. METHODS This single-center study evaluated consecutive patients with histologically proven node-negative early stage cervical cancer (International Federation of Gynecology and Obstetrics 2009 stage IB1-IIB) that was treated using pre-operative brachytherapy and hysterectomy. Pre-brachytherapy staging was performed using magnetic resonance imaging (MRI) and pelvic lymph node assessment was performed using lymphadenectomy. The tumor and cervical tissues were treated using brachytherapy (total dose 60 Gy) followed by Wertheim-type hysterectomy. The study included patients from January 2000 to December 2013. RESULTS A total of 80 patients completed a median follow-up of 6.7 years (range 5.4-8.5). The surgical specimens revealed a pathological complete response for 61 patients (76%). Patients with incomplete responses generally had less than 1 cm residual tumor at the cervix, and only one patient had lymphovascular space involvement. The estimated 5-year rates were 88% for overall survival (95% CI 78% to 94%) and 82% for disease-free survival (95% CI 71% to 89%). Toxicities were generally mild-to-moderate, including 26 cases (33%) of grade 2 late toxicity and 10 cases (13%) of grade 3 late toxicity. Univariate analyses revealed that poor disease-free survival was associated with overweight status (≥25 kg/m2, HR 3.05, 95% CI 1.20 to 7.76, p=0.019) and MRI tumor size >3 cm (HR 3.05, 95% CI 1.23 to 7.51, p=0.016). CONCLUSIONS Pre-operative brachytherapy followed by Wertheim-type hysterectomy may be safe and effective for early stage cervical cancer, although poorer outcomes were associated with overweight status and MRI tumor size >3 cm.

Abstract
French program of breast cancer screening is implemented since15 years and results are in adequation with international guidelines except for participation. To answer to recurrent controversies about breast cancer screening, publications from National Institute of French cancer registry confirm the positive impact of screening on decreasing mortality for participating women. The harms of mammography (and not from screening) need to be communicated to the invited women to help them to make decision about participation but also the risk of worse prognosis in case of symptomatic cancer. The future of screening will be different and works are in progress to find new ways to select women who will beneficiate for screening and whose cancer needs to be treated. Until then, the only way to screen for breast cancer stays the mammographic process as well as other technics in case of dense breast or in case of family history of breast cancer.

REGOSARC: Regorafenib versus placebo in doxorubicin-refractory soft-tissue sarcoma-A quality-adjusted time without symptoms of progression or toxicity analysis. Cancer 2017; 123:2294-2302. [PMID: 28295221 PMCID: PMC5485075 DOI: 10.1002/cncr.30661] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2016] [Revised: 01/11/2017] [Accepted: 01/13/2017] [Indexed: 11/11/2022]
Abstract
BACKGROUND In a placebo‐controlled, randomized phase 2 trial (ClinicalTrials.gov identifier NCT01900743), regorafenib improved progression‐free survival (PFS) for patients with doxorubicin‐pretreated advanced nonadipocytic sarcoma. A quality‐adjusted time without symptoms of progression or toxicity (Q‐TWiST) post hoc exploratory analysis was applied to provide an integrated measure of its clinical benefit. METHODS In the base‐case analysis, each patient's overall survival (OS) was partitioned into 3 mutually exclusive health states: the time with a grade 3 or 4 adverse event (TOX), the time without symptoms of disease or grade 3 or 4 toxicity from treatment, and the time after tumor progression or relapse. The time spent in each state was weighted with a health‐state utility associated with that state and was summed to calculate the Q‐TWiST. The stability of the base‐case analysis was explored with several sensitivity analyses. RESULTS In nonadipocytic sarcoma, the PFS was (4.0 months [2.6‐5.5 months] with regorafenib vs 1.0 month [0.9‐1.8 months] with a placebo; hazard ratio, 0.36 [0.25‐0.53]; P < .0001); the OS was 13.4 months (8.6‐17.3 months) with regorafenib and 9.0 months (6.8‐12.5 months) with a placebo (hazard ratio, 0.67 [0.44‐1.02]). With the classic definition of TOX (including all grade 3 and 4 clinical adverse events), the Q‐TWiSTs were 8.0 months (7.0‐9.0 months) with regorafenib and 5.7 months (4.9‐6.4 months) with a placebo (P < .001). CONCLUSIONS For patients with doxorubicin‐pretreated soft‐tissue sarcoma, regorafenib significantly improved quality‐adjusted survival in comparison with a placebo.

Abstract
737 Background: A is approved in combination with FOLFIRI (A-FOLFIRI) for the treatment of mCRC patients (pts) previously treated with oxaliplatin. PULSAR trial (NCT02173990) aims to measure the activity A-FOLFIRI as 1st-line mCRC treatment. Key secondary objectives are safety, as well as circulating biomarkers and dynamic contrast-enhanced ultrasound measurements as PFS prognosticators. We present here interim analysis of safety and activity. Methods: Pts received A (4 mg/kg I.V.) every 2 weeks in combination with FOLFIRI (Irinotecan: 180 mg/m2, leucovorin: 200 mg/m2, Bolus FU: 400 mg/m2, infusional FU: 2400 mg/m2 over 46hrs). The primary endpoint is 10-month [m] PFS (RECIST 1.1). The target sample size is 72 pts for the following assumptions: P0 = 0.40, P1 = 0.55, α = β = 0.1. Results: Among the first 30 recruited mCRC pts with unresectable metastases (mets), 29 received at least 1 cycle of A-FOLFIRI. 30, 23, and 28 pts were evaluable for survival (intent-to-treat), tumor response, and safety, respectively. Median age was 61.5 (45-82), 70% pts were men. ECOG PS was 0, 1, and 2, in 47%, 43%, and 10% of the pts. 6/30 pts received previous adjuvant chemotherapy. 22/30 pts presented with synchronous mets. 26/30 pts presented with liver mets. Median treatment duration was 6.3m (0.5-24.3) and pts (n = 29) received a median number of 10 cycles (1-37) of A and of 11 cycles (1-43) of FOLFIRI. Median follow-up was 7.2m (1.6-23.9). The 10-m PFS was 59.9% [95%-CI: 37.5-76.5]. Median PFS was 12.9m (95% CI: 6.1-…). 12-m OS rate was 73.7% (95% CI: 48.3-87.9). 5 pts died from PD, and 1 from treatment-related toxicity (colon perforation). 27/28 pts presented at least one severe Adverse Event (AE). Most frequent severe AE (related or not) were hypertension (43%), neutropenia (29%), diarrhea (18%), alkaline phosphatase increase (18%), fatigue (18%), GGT increase (14%), and weight loss (14%). Conclusions: A-FOLFIRI seems promising in 1st line setting mCRC, with respect to PFS. Due to high rates of severe AEs, dose modifications have to be proceeded in a coming protocol amendment.

Multidisciplinary management of advanced ovarian cancer for an optimal therapeutic strategy. EUR J GYNAECOL ONCOL 2017; 38:175-180.

Abstract
The management of advanced ovarian cancer generally requires specialist multidisciplinary teamwork to achieve optimum outcomes. Preoperative computed tomography scans are the imaging modality of choice in determining the extent of disease and aiding in surgical planning. Histological classification is crucial to define various subtypes with their different behaviour and prognosis and to plan the best therapeutic strategy. Pathological prognostic factors, such as histological type, degree of differentiation, and FIGO stage must be described. To determine the ability to optimally cytoreduce advanced ovarian cancer, an experienced gynaecological oncologist needs to explore the entire upper abdomen and the pelvic and para-aortic lymph node regions to define the peritoneal cancer index (PCI). The final assessment is the completeness of cytoreduction (CC) score which is important in predicting prognosis and decision of post-surgical surgery. Ovarian cancer is the leading cause of death from gynaecologic cancers. Initial management is best provided by a specialist multidisciplinary team, including a radiologist, a pathologist, a gynaecologic oncologist, and a medical oncologist.

Abstract
BACKGROUND Dynamic contrast-enhanced ultrasonography (DCE-US) has been used for evaluation of tumor response to antiangiogenic treatments. The objective of this study was to assess the link between DCE-US data obtained during the first week of treatment and subsequent tumor progression. PATIENTS AND METHODS Patients treated with antiangiogenic therapies were included in a multicentric prospective study from 2007 to 2010. DCE-US examinations were available at baseline and at day 7. For each examination, a 3 min perfusion curve was recorded just after injection of a contrast agent. Each perfusion curve was modeled with seven parameters. We analyzed the correlation between criteria measured up to day 7 on freedom from progression (FFP). The impact was assessed globally, according to tumor localization and to type of treatment. RESULTS The median follow-up was 20 months. The mean transit time (MTT) evaluated at day 7 was the only criterion significantly associated with FFP (P = 0.002). The cut-off point maximizing the difference between FFP curves was 12 s. Patients with at least a 12 s MTT had a better FFP. The results according to tumor type were significantly heterogeneous: the impact of MTT on FFP was more marked for breast cancer (P = 0.004) and for colon cancer (P = 0.025) than for other tumor types. Similarly, the differences in FFP according to MTT at day 7 were marked (P = 0.004) in patients receiving bevacizumab. CONCLUSION The MTT evaluated with DCE-US at day 7 is significantly correlated to FFP of patients treated with bevacizumab. This criterion might be linked to vascular normalization.

Abstract
Finding a soft tissue mass in the superficial regions is a common event in daily clinical practice. Correct management of the diagnostic process is crucial to avoid blunders. Diagnosis is posed by pathology, although both imaging and a better understanding of the cellular and molecular mechanisms play an important a role in the characterization, staging and follow-up of soft tissue masses. Cellular and molecular mechanisms can explain either the development of chemo-resistance and the underlying pre- and post-surgery metastasis formation. These are mandatory to improve prognosis and unveil novel parameters predicting therapeutic response. Imaging mainly involves ultrasound and MR and is fundamental not only in diagnosis but also in the first step of therapy: the biopsy. Novel imaging techniques like Ultrasound Elastosonography, Dynamic Contrast-Enhanced MR imaging (DCE), Diffusion Weighted MR imaging (DWI) and MR Spectroscopy (MRS) are discussed. This paper aims at reviewing and discussing pathological methods and imaging in the diagnosis of soft tissue masses underscoring that the most appropriate treatment depends on advanced molecular and radiological studies.

Abstract
OBJECTIVE The Response Evaluation Criteria in Solid Tumors (RECIST) can have limitations when used to evaluate local treatments for cancer, especially for liver malignancies treated by stereotactic body radiation therapy (SBRT). The aim of this study was to validate the relationship between the occurrence of lobulated enhancement (LE) and local relapse and to evaluate the utility of this relationship for predicting local progression. PATIENTS AND METHODS Imaging data of 59 lesions in 46 patients, including 281 computed tomographic (CT) scans, were retrospectively and blindly reviewed by 3 radiologists. One radiologist measured the lesion size, for each CT and overall, to classify responses using RECIST threshold criteria. The second studied LE occurrence. A third radiologist was later included and studied LE occurrence to evaluate the interobserver consistency for LE evaluation. RESULTS The mean duration of follow-up was 13.6 months. LE was observed in 16 of 18 progressive lesions, occurring before size-based progression in 50% of cases, and the median delay of LE detection was 3.2 months. The sensitivity of LE to predict progression was 89%, and its specificity was 100%. The positive predictive value was 100%, the negative predictive value was 95.3%, and the overall accuracy was 97%. The probability of local progression-free survival at 12 months was significantly higher for lesions without LE compared with all lesions: 0.80 (CI 95%: 0.65-0.89) versus 0.69 (CI 95%: 0.54-0.80), respectively. The overall concordance rate between the 2 readers of LE was 97.9%. CONCLUSION Response assessment of liver metastases treated by SBRT can be improved by including LE. This study demonstrates the diagnostic and predictive utility of LE for assessing local progression at a size still eligible for local salvage treatment.

Abstract
Because the majority of patients present advanced disease at diagnosis, the management of epithelial ovarian cancer needs specialist multidisciplinary teamwork. Expertise in surgery, chemotherapy, imaging and histopathology is essential to achieve optimum outcomes. Computed tomography scans are routinely used to determine the extent of disease and to aid in surgical planning. The histologic classification is crucial to plan the best therapeutic strategy and to define the prognosis of disease. Pathological prognostic factors, such as degree of differentiation, FIGO-stage, and histological type have to be described. This report is fundamental to assessing prognosis and selection of appropriate treatment strategy. An adequate staging procedure is an extensive staging by an experienced gynecological oncologist, exploring the entire upper abdomen, and the pelvic and para-aortic lymph node regions to define the Peritoneal Cancer Index (PCI). The final assessment is the completeness of cytoreduction (CC) score, which is an assessment of residual disease after a maximal surgical effort. Initial management of advanced ovarian cancer is best provided by a specialist multidisciplinary team, including a radiologist, a pathologist, a gynecologic oncologist and a medical oncologist.

Abstract
Background Angiogenesis, among other signaling pathways, plays a key-role in sarcoma biology. Regorafenib (RE) has recently been shown to be effective in imatinib and sunitinib-refractory GIST in a phase III trial. Methods/design We are conducting an international trial (France, Austria and Germany) consisting in 4 parallel double-blind placebo-controlled randomized (1/1) phase II trials to assess the activity and safety of RE in doxorubicin-refractory STS (ClinicalTrials.gov: NCT01900743). Each phase II trial is dedicated to one of the 4 following histological subgroups: liposarcoma, leiomyosarcoma, synovial sarcoma and other sarcoma. Within each randomized trial the following stratification factors will be applied: countries and prior exposure to pazopanib. Key-eligibility criteria are: measurable disease, age ≥18, not > 3 previous systemic treatment lines for metastatic disease, metastatic disease not amenable to surgical resection. The primary endpoint is progression-free survival (PFS) according to central radiological review. Secondary endpoints are: Toxicity (NCI-CTC AE V4.0); time to progression; Growth modulation index in pts receiving RE after randomization; 3 and 6 months PFS-Rates, best response rate and overall survival. Each phase II trial will be separately analyzed. In 3 trials, statistical assumptions are: PFS0 = 1.6 & PFS1 = 4.6 months; 1-sided α = 0.1; β = 0.05 with a total sample size of 192 pts. To take into account the rarity of synovial sarcoma, the statistical assumptions are: PFS0 = 1.6 & PFS1 = 4.6 months; 1-sided α = 0.1; β = 0.2 Tumor assessment is done monthly during the 4 first months, and every 3 months thereafter. After central radiological confirmation of tumor progression, an optional open-label option is offered to eligible patients. Discussion The design of this trial allows an assessment of regorafenib activity over placebo in four sarcoma strata and might provide evidence for launching a phase III trial. This study includes both integrative and exploratory translational research program. The study is enrolling since June 2013 (Trial Registration Number: EudraCT N°: 2012-005743-24, on the 15th February 2012).

Abstract
BACKGROUND To assess the additional value of density measurement using contrast-enhancement sequences (Choi assessment) in a real-life cohort of adult soft tissue sarcoma patients treated with trabectedin. METHODS Eligibility criteria included adults (age ⩾18) treated between 01/2007 and 12/2011, with at least two trabectedin cycles after failure or intolerance to doxorubicin/ifosfamide. Baseline and first computed tomography (CT)-scans were centrally reviewed by an experienced radiologist. RESULTS The retrospective cohort consists of 134 (73 female) patients treated with trabectedin 1.5 mg/m(2) given as a 24-h infusion every 3 weeks. Patients received a median of five trabectedin cycles (range: 2-33) and the main cause of discontinuation was progressive disease (PD) (n = 105, 78.4%). Response Evaluation Criteria in Solid Tumours (RECIST) assessment was feasible in 128 (95.5%) patients, with Choi assessment performed in 92 (68.7%) patients, generally due to inadequate sequences or exclusive lung metastases. Concordance between both methods was fair (Kappa = 0.290). We identified five patients with false PD (i.e. PD according to RECIST but stable disease/partial response as per Choi). Univariate analysis did not identify any predictive factors for false PD. Median overall survival (OS) of patients with PD as per RECIST but stable disease/partial response (SD/PR) according to Choi was better than for patients with PD according to both RECIST and Choi (14 months versus 8 months; p = 0.052). CONCLUSIONS Choi assessment may identify patients with false PD who achieved improved efficacy outcomes, suggesting that trabectedin may delay tumour progression even in the case of non-dimensional response. Dual size and tumour density assessment may be more suitable to evaluate responses to trabectedin in sarcoma patients as well as to improve the decision-making strategies for the continuation of trabectedin therapy.

Abstract
OBJECTIVES Dynamic contrast-enhanced ultrasound (DCE-US) has been used in single-center studies to evaluate tumor response to antiangiogenic treatments: the change of area under the perfusion curve (AUC), a criterion linked to blood volume, was consistently correlated with the Response Evaluation Criteria in Solid Tumors response. The main objective here was to do a multicentric validation of the use of DCE-US to evaluate tumor response in different solid tumor types treated by several antiangiogenic agents. A secondary objective was to evaluate the costs of the procedure. MATERIALS AND METHODS This prospective study included patients from 2007 to 2010 in 19 centers (8 teaching hospitals and 11 comprehensive cancer centers). All patients treated with antiangiogenic therapy were eligible. Dynamic contrast-enhanced ultrasound examinations were performed at baseline as well as on days 7, 15, 30, and 60. For each examination, a perfusion curve was recorded during 3 minutes after injection of a contrast agent. Change from baseline at each time point was estimated for each of 7 fitted criteria. The main end point was freedom from progression (FFP). Criterion/time-point combinations with the strongest correlation with FFP were analyzed further to estimate an optimal cutoff point. RESULTS A total of 1968 DCE-US examinations in 539 patients were analyzed. The median follow-up was 1.65 years. Variations from baseline were significant at day 30 for several criteria, with AUC having the most significant association with FFP (P = 0.00002). Patients with a greater than 40% decrease in AUC at day 30 had better FFP (P = 0.005) and overall survival (P = 0.05). The mean cost of each DCE-US was 180&OV0556;, which corresponds to $250 using the current exchange rate. CONCLUSIONS Dynamic contrast-enhanced ultrasound is a new functional imaging technique that provides a validated criterion, namely, the change of AUC from baseline to day 30, which is predictive of tumor progression in a large multicenter cohort. Because of its low cost, it should be considered in the routine evaluation of solid tumors treated with antiangiogenic therapy.

Abstract
BACKGROUND Chemoradiation therapy (CRT) has become the mainstay of locally advanced cervical carcinomas (LACC). However, the price to pay is a significant rate of both early and late colo-rectal toxicities, which may impact on survivors' quality of life. To reduce the incidence of such complications, we suggest a simple technique of pelvic radioprotection. MATERIALS AND METHODS An omental flap is created which is placed to fill the Douglas pouch to both increase the space between rectum and uterine cervix and prevent small bowel to fall in and to be exposed to radiation. In addition, a long sigmoid loop is retracted and fixed in the left paracolic gutter to prevent its irradiation as well. RESULTS From May 2011 to May 2012, 51 successive LACC patients were offered this procedure in addition of a laparoscopic staging. All but 2 with too small an omentum benefitted from omentoplasty, while sigmoidopexy was performed in all but one patient with a long and free sigmoid loop. No immediate adverse effect was observed. The volume of retro-uterine omental flap averaged 7.17 ± 3.79 cm(3). Sequential measurements of the utero-rectal space throughout CRT duration showed a real and durable increase in the distance between these organs, resulting in a drop in the dose of irradiation to recto-sigmoid. With 10 ± 4.5-month median follow-up, we did not observe any rectal or small bowel early or late adverse effects of CRT. CONCLUSIONS Although this series is preliminary, this simple procedure, feasible by laparoscopy (or laparotomy), seems effective to prevent recto-sigmoid as well as small bowel from radio-induced complications due to pelvic CRT.

Abstract
Introduction Myxoid/round-cell liposarcoma (MRCL) is a specific histological subtype that accounts for 30–35% of liposarcomas and whose virulence depends on the quantity of round-cells within the tumor. MRCL is associated with specific chromosomal translocations resulting in the formation of CHOP/FUS and CHOP/EWS fusion proteins. A high sensitivity of MRCL to trabectedin was reported. Case Report We report the case of a 63-year-old woman with a bulky and metastatic MRCL, treated with trabectedin 1.5 mg/m2 as a first-line treatment. She experienced a long-lasting clinical benefit. The patients received 14 cycles of trabectedin and achieved a durable partial response to the metastases and a stable disease of the primary tumor, which is a very favorable safety profile. Also noteworthy is that we have observed a calcification of the primary tumor and the metastasis. The response, which lasted 30 months, led to a symptomatic improvement, associated with an excellent general condition and an absence of pain. Conclusion To the best of our knowledge, this is the first report of a MRCL treated with trabectedin that resulted in a calcification of the primary tumor and the metastases, associated with an outstandingly long response. This case suggests that trabectedin may represent a feasible first-line therapeutic option for patients with MRCL, with meaningful clinical benefits and an acceptable safety profile.

Abstract
526 Background: Tyrosine kinase inhibitors including sunitinib are the most effective treatments of metastatic renal cell carcinoma (mRCC). A multi-centric study of 539 patients (different tumors treated anti-angiogenic treatments) evaluating dynamic contrast-enhanced ultrasound (DCE-US), showed that a decrease of AUC (Area under the curve) correlated to the blood volume at one month is predictive of response. Our first objective was to validate the correlation between this parameter and the PFS in a sub-group of mRCC treated with Sunitinib The second objective was to study the variability of AUC. Methods: Each Patient had CT-scan every 2 months in order to evaluate the Response assessment using the Response Evaluation Criteria in Solid Tumors (RECIST 1.1).DCE-US were performed at baseline and at D30. At each examination, we quantified 7 DCE-US parameters after bolus injection of contrast agent and mathematical modelization of raw linear data recorded during 3 minutes. We also estimated the variation between baseline and D30. The main endpoint was progression free survival assessed according to RECIST. We first selected the best parameters. We studied the trend between the parameter value and freedom from progression. After, the best cut-points were searched through a grid search. The best single cut-point was that with the lowest P-value for progression free survival. We performed this analysis in the sub-group of patients with mRCC treated with sunitinib. Morever, we studied the variability of AUC in 30 other patients treated with TKI . We performed in this group 2 DCE-US the same day before and after lunch. Results: A total of 81 mRCC patients treated with sunitinib were selected. All had DCE-US at baseline and one month. The median of follow-up was 18 months. For DCE-US, the decrease of 90 % of AUC at D 30 was correlated to the PFS (p =0.03). The difference of PFS between the groups defined by this cut-point was 4 months (bad responders) and 14 months (good responders). The results of variability are on-going. Conclusions: The decrease of more than 90% of AUC with DCE-US at one month is a potential predictive biomarker of response in mRCC patients treated with sunitinib. The results of variability of this parameter will be also presented. Clinical trial information: no. 912346.

Abstract
BACKGROUND Based on registries, the European experience has been that <50% of patients are treated according to protocols and/or benefit from the minimum required surgery for ovarian cancer. The French Cancer Plan 2009-2013 considers the definition of qualitative indicators in ovarian cancer surgery in France. This endeavour was undertaken by the French Society of Gynaecologic Oncology (SFOG) in partnership with the French National College of Obstetricians and Gynecologists and all concerned learned societies in a multidisciplinary mindset. METHODS The quality indicators for the initial management of patients with ovarian cancer were based on the standards of practice determined from scientific evidence or expert consensus. RESULTS The indicators were divided into structural indicators, including material (equipment), human (number and qualification of staff), and organizational resources, process indicators, and outcome indicators. CONCLUSIONS The enforcement of a quality assurance programme in any country would undoubtedly promote improvement in the quality of care for ovarian cancer patients and would result in a dramatic positive impact on their survival. Such a policy is not only beneficial to the patient, but is also profitable for the healthcare system.

Abstract
PURPOSE To determine whether it is appropriate to routinely undertake surgery if flat epithelial atypia (FEA) or pure flat epithelial atypia (pFEA) is found on large-core biopsy. PATIENTS AND METHODS Between 2005 and 2010, 1678 large-core biopsy procedures were carried out, which led to 136 FEA sites being identified, 63 of which across 59 patients were pFEA (four patients had two sites of pFEA each). Forty-eight patients underwent further surgical excision, equating to 52 excised sites of pFEA. RESULTS Of the 52 operated sites, there were 20 benign lesions (38%), 26 borderline lesions (56%), and three ductal carcinomas in situ (6%). The rate of histologic underestimation was put at 3.8%. Of the three cases that were underestimated, one was discarded because the definitive histology was not representative of the site from which microcalcifications had initially been taken. The other two cases that were underestimated were found in patients with an increased individual risk of breast cancer. CONCLUSION In patients with no personal or first-degree family history of breast cancer, after complete or subtotal excision under radiology of the radiological lesion, and while excluding images fitting BI-RADS 5, annual monitoring may be offered as an alternative to surgical excision in view of the absence of underestimation found in our study.
