Exploratory analysis of the effect of a dexamethasone-sparing regimen for prophylaxis of cisplatin-induced emesis on food intake (LUNG-NEPA study)

We demonstrated the non-inferiority of a dexamethasone (DEX)-sparing (single-dose) regimen with NEPA, a netupitant/palonosetron fixed combination, for preventing chemotherapy-induced nausea and vomiting (CINV) caused by cisplatin. This pre-planned exploratory analysis assessed the effect of the DEX-sparing regimen on a patient's food intake. Chemotherapy-naïve patients undergoing cisplatin (≥ 70 mg/m2) were given NEPA and DEX (12 mg) on day 1 and randomized to receive either no further DEX (DEX1), or oral DEX (4 mg BID) on days 2-4 (DEX4). Patient-reported endpoint maintenance of usual daily food intake was assessed during the 5-days post-chemotherapy. The relationship between usual daily food intake and CINV control, pre-chemotherapy self-rated food intake and BMI-adjusted weight loss (WL) were evaluated. One-hundred fifty-two patients (76/group) were assessable. The proportion of patients reporting maintenance of usual daily food intake was similar in both groups: 69.7% (95% CI, 58.6-78.9) for DEX1 vs. 72.4% (95% CI, 61.4-81.2) for DEX4. Only CINV control was significantly associated with maintenance of usual daily food intake (P ≤ 0.001) during the overall phase. The DEX-sparing regimen does not adversely affect patient-reported daily food intake post-chemotherapy. The current analysis adds further insights into antiemetic efficacy of DEX sparing beyond day 1 in the challenging setting of cisplatin.Trial registration: The parent study was registered on ClinicalTrials.gov (NCT04201769).

Evaluating the impact of chemotherapy-induced nausea and vomiting on daily functioning in patients receiving dexamethasone-sparing antiemetic regimens with NEPA (netupitant/palonosetron) in the cisplatin setting: results from a randomized phase 3 study

Background

The non-inferiority of dexamethasone (DEX) on day 1, with or without low-dose DEX on days 2 and 3, combined with oral NEPA (netupitant/palonosetron), compared with the guideline-consistent use of DEX was demonstrated in cisplatin. Here, we complete the analysis by assessing the impact of emesis on daily lives of patients receiving DEX-sparing regimens using the Functional Living Index-Emesis (FLIE).

Methods

Chemotherapy-naïve patients undergoing cisplatin (≥70 mg/m²), were given NEPA and DEX (12 mg) on day 1 and randomized to receive either 1) no further DEX (DEX1), 2) oral DEX (4 mg daily) on days 2–3 (DEX3), or 3) DEX (4 mg twice daily) on days 2–4 (DEX4; control). Patients completed the FLIE questionnaire on day 6 of cycle 1. Endpoints included the FLIE nausea domain, vomiting domain, and overall combined domain scores, as well as the proportion of patients with no impact on daily life (NIDL; overall score > 108). This was a protocol-planned analysis.

Results

In the DEX1 group, no significant differences were observed in the FLIE nausea score (48.9 [±1.8; SE] vs. 53.7 [±1.5]), vomiting score (56.6 [±1.4] vs. 58.7 [±0.8]) and overall score (105.6 [±2.8] vs.112.4 [±1.9]) versus DEX4 control; similar results were observed in the DEX3 group for nausea score (49.6 [±1.7]), vomiting score (58.2 [±1]) and overall score (107.8 [±2.4]) versus control. There were no significant between-group differences in the proportion of patients reporting NIDL.

Conclusion

Reducing DEX, when administered with NEPA, does not seem to adversely impact the daily functioning in patients undergoing cisplatin.

[Management of small cell lung cancer patient in the regions of Lazio, Umbria and Sardinia.]

Small cell lung cancer (SCLC) is an aggressive disease, difficult to treat. There have been no significant therapeutic advances over platinum and etoposide chemotherapy in the last 20 years until the introduction of immunotherapy. In 2020 atezolizumab, an immune checkpoint inhibitor against PD-L1 was approved in Italy in combination with carboplatin and etoposide for the first-line treatment of patients with extensive stage disease (ES-SCLC), becoming the new standard treatment. On May 20, 2021, a virtual meeting, directed by profs. Federico Cappuzzo and Emilio Bria, was held in which 14 clinicians from different oncology centers in Lazio, Umbria and Sardinia discussed the issues of ES-SCLC patients treatment, after the advent of immunotherapy. The aim of the meeting was to share their clinical experience and to provide a series of practical indications that can support clinicians in the management of ES-SCLC patients in first-line with chemo-immunotherapy.

Dexamethasone-Sparing Regimens with Oral Netupitant and Palonosetron for the Prevention of Emesis Caused by High-Dose Cisplatin: A Randomized Noninferiority Study

Background

To reduce the overall exposure to dexamethasone (DEX) in patients receiving cisplatin‐based chemotherapy, we evaluated the noninferiority of DEX on day 1, with or without low‐dose DEX on days 2 and 3, combined with an oral fixed‐dose combination of netupitant and palonosetron (NEPA), compared with the guideline‐consistent use of 4‐day DEX.

Patients and Methods

In this open‐label, multicenter study, chemotherapy‐naïve patients undergoing high‐dose cisplatin (≥70 mg/m²), were given NEPA and DEX (12 mg) on day 1 and randomized (1:1:1 ratio) to receive either (a) no further DEX (DEX1), (b) oral DEX (4 mg daily) on days 2–3 (DEX3), or (c) DEX (4 mg twice daily) on days 2–4 (DEX4). The primary efficacy endpoint was complete response (CR: no emesis and no rescue medication) during the 5‐day overall phase. The noninferiority margin was set at −15% difference (DEX1 or DEX3 minus DEX4). Secondary efficacy endpoints included complete protection (CP: CR and none or mild nausea).

Results

Two‐hundred twenty‐eight patients, 76 in each arm, were assessable. Noninferiority was met for both DEX‐sparing regimens and the reference arm, with overall phase CR rates of 76.3% in each of the DEX1 and DEX3 arms and 75.0% in the DEX4 arm (95% confidence interval, −12.3% to 15% for each comparison). During the overall phase, CP rates were similar between groups.

Conclusion

A simplified regimen of NEPA plus single‐dose DEX offers comparable chemotherapy‐induced nausea and vomiting prevention throughout 5 days post‐chemotherapy with the advantage of sparing patients additional doses of DEX in the high–emetic‐risk setting of cisplatin‐based chemotherapy.

Implications for Practice

Dexamethasone (DEX) has traditionally played an integral role in the management of chemotherapy‐induced emesis. Although generally considered safe, even short‐term DEX use is associated with various side effects, and some evidence suggests that concurrent steroids may reduce the efficacy of immunotherapies. This study demonstrates comparable antiemetic control during the 5 days post‐chemotherapy with a simplified regimen of netupitant/palonosetron plus single‐dose DEX versus the standard 4‐day DEX reference treatment in high‐dose cisplatin. This represents a clinically relevant achievement as it not only simplifies antiemetic prophylaxis but also offers an opportunity to appropriately use in patients where caution with corticosteroid use is advised.

This study was designed to test whether two different dexamethasone‐sparing regimens, when administered with NEPA, might provide the opportunity to reduce the total corticosteroid dose while maintaining the same degree of chemotherapy‐induced nausea and vomiting control in patients undergoing cisplatin‐based chemotherapy.

Long-term outcome of pemetrexed maintenance for advanced nonsquamous non-small-cell lung cancer: a real-world observational cohort study

INTRODUCTION

Pemetrexed maintenance significantly improved progression-free survival (PFS) and overall survival (OS) in advanced nonsquamous non-small-cell lung cancer (NSCLC) patients not progressing after induction chemotherapy.

OBJECTIVES

This study is aimed at examine the association of various clinical factor and survival in a real-world cohort analysis.

MATERIALS AND METHODS

One hundred ninety-four patients were included and classified as "PM" cohort ("Pemetrexed Maintenance", including patients given with pemetrexed maintenance after induction chemotherapy, n=112), and "noPM" cohort ("no Pemetrexed Maintenance" including those discontinuing pemetrexed, n=82).

RESULTS

The median PFS was 8.8 and 5.4 months in the PM and noPM cohorts, respectively (p=0.001). The median OS was 19.6 months in the "PM" cohort and 13.2 months in the "noPM" cohort (p<0.02). In the multivariate analysis, ECOG Performance Status (PS) 0 and maintenance therapy were independently associated with improved PFS and OS. A longer median PFS was reported in patients given ≥5 cycles of pemetrexed maintenance (p<0.01).

DISCUSSION

These results further confirm the survival benefit of pemetrexed maintenance in a real-word population. All eligible advanced NSCLC patients should be strongly considered for at least 5 of pemetrexed maintenance.

Molecular imaging in immuno-oncology: current status and translational perspectives

Introduction: Only 20-40% of patients respond to therapy with immune checkpoint inhibitors (ICIs). Therefore, the early identification of subjects that can benefit from such therapeutic regimen is mandatory. Areas covered: The immunobiological mechanisms of ICIs are briefly illustrated. Furthermore, the limitations of traditional radiological approaches are covered. Then, the pros and cons of molecular imaging through positron emission computed tomography (PET/CT) are reviewed, with a particular focus on ¹⁸f-fluorodeoxyglucose (¹⁸F-FDG) and PET-derived metabolic parameters. Lastly, translational perspective of radiopharmaceuticals others than ¹⁸F-FDG such as ⁸⁹zirconium (⁸⁹Zr) or fluorine-18 (¹⁸F) labeled monoclonal antibodies (e.g.⁸⁹Zr-atezolizumab, ⁸⁹Zr-nivolumab) binding to specific biomarkers are discussed. Expert opinion: Molecular imaging presents a prominent role for the management of oncological patients treated with ICIs. Preliminary clinical data indicate that PET/CT with ¹⁸F-FDG is useful for assessing the response to treatment and for the imaging of immune-related adverse effects. Nevertheless, the methodological approach (iPERCIST, PERCIMT, or others) to be used for an optimal diagnostic accuracy and patients' evaluation is still a debated issue. PET/CT with radioligands directed toward ICIs biomarkers, although is still in a translational phase, holds the promise of accurately predicting the response to treatment and revealing the acquired resistance to immunotherapy.

Prognostic clinical factors in patients affected by non-small-cell lung cancer receiving Nivolumab

Background: Immune-checkpoint inhibitors have radically changed the treatment landscape of Non-Small-Cell Lung Cancer (NSCLC). It is still unclear whether specific clinical characteristics might identify those patients benefiting from immunotherapy more than others. The aim of this study was to identify clinical characteristics associated with disease-specific survival (DSS), time-to-treatment failure (TTF), objective responses (OR) and progressive disease (PD) in NSCLC patients treated with Nivolumab.Methods: This was a multicenter retrospective study conducted on 294 patients treated with Nivolumab for advanced NSCLC.Results: Of the more than 50 variables analyzed, five showed a significant correlation with DSS: ECOG PS, size of the biggest brain metastasis, number of metastatic sites, toxicity, and malignant pleural effusion. Three variables significantly correlated with TTF: malignant pleural effusion, number of metastatic sites, number of liver metastases. Malignant pleural effusion was the only variable showing a significant correlation with OR, as well as the only one correlating with all the endpoints of the study.Conclusions: This study identified clinical characteristics associated with survival and response during treatment with Nivolumab in NSCLC patients. The unfavorable association between malignant pleural effusion and objective response is a novel finding with important translational implications.

Be-TeaM: An Italian real-world observational study on second-line therapy for EGFR-mutated NSCLC patients

OBJECTIVES

Molecular diagnostics and care of non-small cell lung cancer (NSCLC) are continuously evolving. Few data document the current strategies to manage advanced NSCLC patients beyond progression in clinical practice.

PATIENTS AND METHODS

Be-TeaM is an Italian multi-center observational study conducted on consecutive EGFR-mutated stage IV NSCLC patients, progressed during/after a first-line EGFR-TKI. It consists of a retrospective phase, from first-line EGFR-TKI therapy start until study entry (i.e. beginning of the diagnostic process), and a prospective phase, until treatment choice or for 3 months if no therapy was prescribed. Primary objective was to describe the diagnostic and therapeutic approaches adopted after progression in a real-world setting.

RESULTS

Of 308 patients enrolled in 63 centers from July 2017 to June 2018, 289 were included in the analysis. In first line, 53.3 % received gefitinib, 32.5 % afatinib and 14.2 % erlotinib. The testing rate (i.e. rate of all patients undergone any biopsy -liquid and/or tissue- for the T790 M detection) was 90.7 %, with liquid biopsy being the most frequently executed. Of 262 biopsied patients, 64.5 % underwent only 1 liquid biopsy, 10.7 % only 1 tissue biopsy and 18.3 % >1 biopsy, both liquid and solid in 85.4 %. The T790M positivity rate was 45.3 %; of 166 patients undergone only a liquid biopsy and tested for the mutation, 39.8 % were T790M+ and 60.2 % T790M-/undetermined. By the observation end, 87.9 % patients had a post-progression treatment chosen, osimertinib being the most frequent among the T790M+.

CONCLUSION

Be-TeaM provides the first snapshot of current practices for the management of NSCLC patients beyond progression in Italy; in clinical practice, assessing the T790M status is not always feasible.

Real-world outcomes according to treatment strategies in ALK-rearranged non-small-cell lung cancer (NSCLC) patients: an Italian retrospective study

PURPOSE

Anaplastic lymphoma kinase (ALK) rearrangement confers sensitivity to ALK inhibitors (ALKis) in non-small-cell lung cancer (NSCLC). Although several drugs provided an impressive outcome benefit, the most effective sequential strategy is still unknown. We describe outcomes of real-life patients according to the treatment strategy received.

PATIENTS

We retrospectively collected 290 ALK rearranged advanced NSCLC diagnosed between 2011 and 2017 in 23 Italian institutions.

RESULTS

After a median follow-up of 26 months, PFS for crizotinib and a new generation ALKis were 9.4 [CI 95% 7.9-11.2] and 11.1 months [CI 95% 9.2-13.8], respectively, while TTF were 10.2 [CI 95% 8.5-12.6] and 11.9 months [CI 95% 9.7-17.4], respectively, being consistent across the different settings. The composed outcomes (the sum of PFS or TTF) in patients treated with crizotinib followed by a new generation ALKis were 27.8 months [CI 95% 24.3-33.7] in PFS and 30.4 months [CI 95% 24.7-34.9] in TTF. The median OS from the diagnosis of advanced disease was 39 months [CI 95% 31.8-54.5]. Patients receiving crizotinib followed by a new generation ALKis showed a higher median OS [57 months (CI 95% 42.0-73.8)] compared to those that did not receive crizotinib [38 months (CI 95% 18.6-NR)] and those who performed only crizotinib as target agent [15 months (CI 95% 11.3-34.0)] (P < 0.0001).

CONCLUSION

The sequential administration of crizotinib and a new generation ALKis provided a remarkable clinical benefit in this real-life population, being an interesting option to consider in selected patients.

Efficacy of nivolumab in pre-treated non-small-cell lung cancer patients harbouring KRAS mutations

BACKGROUND

The present study investigated the efficacy and safety of nivolumab in pre-treated patients with advanced NSCLC harbouring KRAS mutations.

METHODS

Clinical data and KRAS mutational status were analysed in patients treated with nivolumab within the Italian Expanded Access Program. Objective response rate, progression-free survival and overall survival were evaluated. Patients were monitored for adverse events using the National Cancer Institute Common Terminology Criteria for Adverse Events.

RESULTS

Among 530 patients evaluated for KRAS mutations, 206 (39%) were positive while 324 (61%) were KRAS wild-type mutations. KRAS status did not influence nivolumab efficacy in terms of ORR (20% vs 17%, P = 0.39) and DCR (47% vs 41%, P = 0.23). The median PFS and OS were 4 vs 3 months (P = 0.5) and 11.2 vs 10 months (P = 0.8) in the KRAS-positive vs the KRAS-negative group. The 3-months PFS rate was significantly higher in the KRAS-positive group as compared to the KRAS-negative group (53% vs 42%, P = 0.01). The percentage of any grade and grade 3-4 AEs were 45% vs 33% (P = 0.003) and 11% vs 6% (P = 0.03) in KRAS-positive and KRAS-negative groups, respectively.

CONCLUSIONS

Nivolumab is an effective and safe treatment option for patients with previously treated, advanced non-squamous NSCLC regardless of KRAS mutations.

Non Conventional Fractionation in Radiotherapy of the Musculo-Skeletal Sarcomas

In 1989 we started an accelerated hyperfractionated schedule of radiotherapy (two 1.6 Gy daily fractions) in standard risk localized Ewing's sarcoma of bone, with the aim at reducing late effects in young patients and at improving disease control through a better integration of treatment modalities. From 1991, the same schedule was used in preoperative radiotherapy of adult soft tissue sarcomas of the extremities: the main purpose was to reduce the time to surgery and to evaluate surgical complications in comparison with a previous experience of hypofractionated radiotherapy (one 3 Gy daily fraction). From 1991 to 1997, 76 patients with Ewing's sarcoma and 24 patients with soft tissue sarcoma were treated at our Institution. Results and complication rates are analyzed in comparison with historical data. In Ewing's sarcoma, a correct evaluation of improvement in local control was difficult because of changing treatment policy (bulky disease was not included in the present series). Late effects, as evaluated in patients with a minimum follow-up of 3 years, occurred with similar incidence, but at higher total dose levels in patients treated with accelerated hyperfractionation. In patients with soft tissue sarcomas, incidence of surgical complications is reduced as compared to historical experience. Major problems of wound healing were seen in association with intraoperative brachitherapy boost.

Fulminant Hepatic Failure Caused by Diffuse Intrasinusoidal Metastatic Liver Disease: A Case Report

A 53-year-old woman experienced rapidly progressing liver failure four years after a quadrantectomy for a breast carcinoma. She had received adjuvant chemotherapy and radiotherapy, and second-line chemotherapy for bone metastasis one year earlier. The hepatic failure manifested with ascites, jaundice, elevation of serum bilirubin and hepatic enzyme levels and hypoalbuminemia. Imaging studies showed an enlarged liver without metastatic lesions. The patient died of hepatic decompensation within two weeks. Liver examination at autopsy revealed massive neoplastic infiltration consistent with a primary breast carcinoma. It is important to realize that this unusual pattern of liver metastasis cannot be demonstrated even with the most advanced techniques of instrumental diagnosis (CT scan, ultrasonography and magnetic resonance imaging), and should be taken into account in the differential diagnosis of rapidly progressing liver failure.

Ceritinib compassionate use for patients with crizotinib-refractory, anaplastic lymphoma kinase-positive advanced non-small-cell lung cancer

Aim: Ceritinib was evaluated within a compassionate use program of Italian patients. Patients & methods: 70 patients with anaplastic lymphoma kinase-positive crizotinib-refractory advanced non-small-cell lung cancer received ceritinib. Results: Overall response was 40.6%, median progression-free survival was 8.2 months and median survival was 15.5 months. Dose reduction due to treatment-related adverse events occurred in 50.8% of patients starting at 750 mg/day. No significantly different progression-free survival was observed between patients who underwent any time dose reduction (n = 38) versus those who remained on the recommended dose of 750 mg/day (n = 32; p = 0.07). Conclusion: The efficacy of ceritinib compassionate use program resembled that of clinical trials. Dose reductions and adjustments did not appear to negatively affect clinical outcome.

Short Hydration Regimen and Nephrotoxicity of Intermediate to High-Dose Cisplatin-Based Chemotherapy for Outpatient Treatment in Lung Cancer and Mesothelioma

Aims and Background

Cisplatin, a standard component of combination chemotherapy for several tumors, presents important anti-tumor properties but also several toxic effects. In particular, the major dose-limiting effect appears to be renal toxicity. In several countries, to reduce nephrotoxicity after cisplatin administration, a 24-h hydration is recommended following a chemotherapy treatment in a hospital regimen. In our Institutions, cisplatin chemotherapy is an outpatient treatment that provides adequate hydration with an NaCl solution plus furosemide and diuresis monitoring during treatment.

Methods and Study Design

To assess incidence of cisplatin nephrotoxicity using a short hydration regimen, which included 2000 ml of fluids with control of diuresis, individual outpatient data was pooled retrospectively from patients enrolled in large randomized studies regarding cisplatin-based chemotherapy in lung cancer and mesothelioma. From February 1999 to November 2002, 107 patients treated with cisplatin (≥75 mg/m2/cycle) were examined, monitoring serum creatinine and creatinine clearance levels.

Results

Five patients out of 107 (4.6%) were withdrawn from chemotherapy because of renal toxicity. For the other 102 patients, serum creatinine and creatinine clearance measurements were stable around the normal values during treatment. No time trends relating to serum creatinine levels or creatinine clearance and cycle numbers or cisplatin-cumulative doses were detected (P = 0.36 and P = 0.64, for the relationship with cycle number, and P = 0.39 and P = 0.65 for the relationship with cumulative dose, respectively, random effect model) after adjusting for the total number of cycles administered.

Conclusions

These observations indicate that intermediate to high-dose cisplatin administration is feasible in outpatient management with a short hydration regimen without high risk of nephrotoxicity.

Off-Label Prescription of Antineoplastic Drugs: An Italian Prospective, Observational, Multicenter Survey

Aims and Background

An appropriate use of drugs should follow the registered indications. Different reasons can induce oncologists to prescribe drugs off-label. The aim of this study was to describe incidence and characteristics of these prescriptions in Italy.

Methods

Patients submitted to chemotherapy in 15 Italian oncology centers were evaluated for two randomized non-consecutive days of two weeks in May 2006.

Results

The study enrolled 644 patients receiving 1,053 drugs. Overall, 199 of 1053 (18.9%) prescriptions were off-label. In 92 of 199 cases (46.2%), the drugs were used for a neoplasm for which they were not approved, but there was scientific evidence (one or more randomized clinical trials or more phase II studies published in a major oncology journal) justifying the prescription. In 27 cases (13.6%), the drugs were prescribed for a rare neoplasm (cisplatin and gemcitabine in mesothelioma). In 20/21 cases (10.1%/10.5%), drugs were used in association/alone in contrast with the approved use (capecitabine in association in colorectal cancer). In 28/11 cases (14.0%/5.6%), the drugs were used in lines of chemotherapy subsequent/previous to that approved.

Conclusions

Off-label use of antineoplastic drugs, in this observational survey, represents less than 20% of the prescriptions, and most of them are based on scientific evidence of efficacy.

Inappropriate Doses of Chemotherapy in Italian Breast Cancer Patients Enrolled in Clinical Trials

Aims and background

The dose of delivered chemotherapy is important to evaluate the appropriateness of the anticancer treatment. This aspect has been scarcely studied in Italy. About 7 years ago, the Italian Group for Antiemetic Research (IGAR) published a large controlled study on the effectiveness of different antiemetic prophylaxis in patients submitted to moderately emetogenic chemotherapy, where the prescribed chemotherapy was recorded. The aim of our study was to evaluate the incidence of undertreatment and to detect clinical and nonclinical factors able to explain its variability.

Methods

An observational study on the IGAR databank was performed to evaluate the incidence of undertreatment in the prescription in conditions of clinical trial, where the doses belonged to the eligibility criteria, and to analyze the importance of clinical and nonclinical factors using multifactorial logistic models.

Results

317 patients receiving cyclophosphamide, methotrexate, and fluorouracil (CMF) and 224 anthracycline-based chemotherapy were considered. In the CMF-treated patients, 22.4% received full doses, whereas in 53.6% all three drugs of the schedule were down-dosed. In the anthracycline-treated group, 38.6% and 3.4% of patients submitted to chemotherapy containing epirubicin and doxorubicin, respectively, were undertreated. Logistic models showed that undertreatment in CMF-treated patients depended significantly on the geographic area and setting of chemotherapy administration. Although not significant, differences between age class and Karnofsky performance status were also detected. In the epirubicin-treated group, all these factors were significant.

Conclusions

The undertreatment of cancer patients is a relevant problem, because it could give, in daily clinical practice, worse results than those reported in clinical studies. Considering the setting of a clinical trial where our study was carried out, the incidence of undertreatment is surprisingly high. We do not know whether today, about 8 years after the IGAR study was carried out, the inappropriate dose of chemotherapy is still as frequent as we reported, but surely the topic deserves more attention.

Listening understanding and acting (lung): focus on communicational issue in thoracic oncology

Background

In the field of oncological assistance, nowadays we have to deal with a complex scenario where patients got used to obtain a huge amount of information through internet or social media and to apply them in performing their health-related decisions. This landscape requires that clinicians become able to handle therapeutical approaches and adequate skills in communication tools to satisfy the current needs. Our project aimed to build a communication model based on clinical oncologists’ real experiences in order to find a simple way to share with patients all the innovative therapeutical opportunities today available in lung cancer. The final goal is to design a flexible and personalized model adaptable to clinician’s personal characteristics and to the specific patient he is facing. We applied both traditional educational tools and innovative techniques in order to make the results effective and applicable to support peer learning.

Methods

The first step consisted in a Board synthesized the definition of the diagnostic process, the identification of treatment strategies and any potential communication barrier clinicians may face dealing with patients. The second step consisted in teamwork including a theoretical part and a training part. In the third step we produce five training videos and video interviews regarding communication praxis and a “Small communication manual”. The last step consisted in the publication of the produced material on website and its diffusion through the social media.

Results

In medicine, the universal application of a single model of communication does not represent the optimal solution. By contrary, the availability of simple and practical suggestions to improve the communicative style could allow clinicians to abandon stereotyped formulas identically repurposed to all patients. The “from bottom to top” training, starting from real-life to take advantage of the clinician’s experience, give the clinicians the possibility to meditate about their own communicative style and to train in the context of a protected environment. Applying these rules, we design an effective communication model, based on healthcare humanization, which could represent a fundamental support for the patient in order to be gently driven by the clinician to the most appropriate therapeutical choice, balancing efficacy and quality of life. The relational training may improve the quality of clinician-patient communication and could be widespread to other clinicians through the media.

Conclusions

Considering the innovative therapeutical options available, particularly for lung cancer patients, and the increasing access of health-related information through internet or social media the clinician-patient communication has become crucial to support the achievement of the most appropriate therapeutical choice for the patient, facing the intricate illness experience. Building a shareable and easy-to-apply communication model represents a challenge aimed to help clinicians and including technology not as a threat, but as a positive tool.

BE-POSITIVE: Beyond progression after tyrosine kinase inhibitor in EGFR- positive non small cell lung cancer patients: Results from a multicenter Italian observational study

OBJECTIVES

Non-small-cell-lung-cancer (NSCLC) patients harbouring epidermal growth factor receptor (EGFR) mutations develop drug resistance after 9-12 months of EGFR tyrosine kinase inhibitors (TKIs) therapy pointing out the issue of the second-line treatment choice.

MATERIALS AND METHODS

From June 2009 until May 2013 patients affected by advanced NSCLC harbouring EGFR mutations receiving first-line TKI were collected mainly retrospectively in 24 Italian Centers. Primary objective was to describe the percentage of EGFR mutated patients receiving second-line therapy after progression to first-line EGFR-TKIs assessing the type, the activity in terms of objective response rate (ORR), efficacy in terms of progression free survival (PFS) and overall survival (OS), and safety of second-line treatment. Secondary objective was to describe the efficacy of first-line EGFR-TKIs.

RESULTS

312 patients were included. Most of them were females (203, 65.1%), never smokers (200, 64.1%), with adenocarcinoma histology (290, 92.9%). The most common mutations were EGFR exon 19 deletion and L858R, detected in 186 and 97 cases (59.6% and 31.1%), respectively. At data cut-off, 274 patients (95.1%) received any second-line treatment (including best supportive care or local treatments only). A total of 163 patients received second-line systemic therapy with an ORR of 20.9% (95% CI:14.62-27.10), a median PFS and OS of 4.7 (95% CI:3.81-5.26) and 24.5 (95% CI:21.65-27.37) months, respectively. Grade 3-4 hematological and non-hematological toxicities were reported in 9% and 6.3% of 144 patients treated with chemotherapy while non-hematological toxicity was reported in 4 cases of the 17 patients receiving second-line target agents.

CONCLUSIONS

BE-Positive is the first multicenter observational study reporting outcomes of therapies in a "real-life Caucasian EGFR-mutated population", highlighting the need of further researches about new treatment strategies in this setting.

Value of KRAS as prognostic or predictive marker in NSCLC: results from the TAILOR trial

BACKGROUND

The prognostic and predictive role of KRAS mutations in advanced nonsmall-cell lung cancer (NSCLC) is still unclear. TAILOR prospectively assessed the prognostic and predictive value of KRAS mutations in NSCLC patients treated with erlotinib or docetaxel in second line.

PATIENTS AND METHODS

NSCLC patients from 52 Italian hospitals were genotyped for KRAS and EGFR mutational status in two independent laboratories. Wild-type EGFR patients (N = 218) received first-line platinum-based chemotherapy and were randomly allocated at progression to erlotinib or docetaxel. Overall survival (OS) according to KRAS mutational status was the primary end point.

RESULTS

KRAS mutations were present in 23% of TAILOR randomized cases. The presence of a KRAS mutation did not adversely affect progression-free (PFS) or overall (OS) survival [hazard ratio (HR) PFS = 1.01, 95% confidence interval (CI) 0.71-1.41, P = 0.977; OS = 1.24, 95% CI 0.87-1.77, P = 0.233], nor influenced treatment outcome (test for interaction: OS P = 0.965; PFS P = 0.417). Patients randomized to docetaxel treatment experienced longer survival independently from the KRAS mutational status of their tumors (HR: mutated KRAS 0.81, 95% CI 0.45-1.47; wild-type KRAS 0.79, 95% CI 0.57-1.10).

CONCLUSION

In TAILOR, KRAS was neither prognostic nor predictive of benefit for either docetaxel or erlotinib. Docetaxel remains superior independently from KRAS status for second-line treatment in EGFR wild-type advanced NSCLC patients.

Male breast cancer: clinical features and multimodal treatment in a retrospective survey analysis at Italian centers

AIMS AND BACKGROUND

We report a collection of data about early breast cancer in male patients from 13 Italian institutions.

METHODS AND STUDY DESIGN

We obtained data from patient charts and performed statistical analysis. The primary end points were overall survival and disease-free survival.

RESULTS

A total of 205 men with invasive breast cancer was identified, with a median age of 66 years. Pathological characteristics were heterogeneous for T stage, N stage and HER2 status. Histological subtype was predominantly ductal infiltrating carcinoma. Most of them were hormone receptor positive. Mastectomy was the most common strategy. Postsurgical treatment was not standardized. Patients with large tumors were more likely to be treated with chemotherapy. Disease recurrence was associated with an ER+ and PR+ status.

CONCLUSIONS

We identified a correlation between relapse and hormone receptor expression, as is the case in female breast cancer.

Erlotinib versus docetaxel as second-line treatment of patients with advanced non-small-cell lung cancer and wild-type EGFR tumours (TAILOR): a randomised controlled trial

BACKGROUND

Erlotinib is registered for treatment of all patients with advanced non-small-cell lung cancer (NSCLC). However, its efficacy for treatment of patients whose tumours are EGFR wild-type-which includes most patients-is still contentious. We assessed the efficacy of erlotinib compared with a standard second-line chemotherapy in such patients.

METHODS

We did this randomised controlled trial in 52 Italian hospitals. We enrolled patients who had metastatic NSCLC, had had platinum-based chemotherapy, and had wild-type EGFR as assessed by direct sequencing. Patients were randomly assigned centrally (1:1) to receive either erlotinib orally 150 mg/day or docetaxel intravenously 75 mg/m(2) every 21 days or 35 mg/m(2) on days 1, 8, and 15, every 28 days. Randomisation was stratified by centre, stage, type of first-line chemotherapy, and performance status. Patients and investigators who gave treatments or assessed outcomes were not masked to treatment allocation, investigators who analysed results were. The primary endpoint was overall survival in the intention-to-treat population. The study is registered at ClinicalTrials.gov, number NCT00637910.

FINDINGS

We screened 702 patients, of whom we genotyped 540. 222 patients were enrolled (110 assigned to docetaxel vs 112 assigned to erlotinib). Median overall survival was 8·2 months (95% CI 5·8-10·9) with docetaxel versus 5·4 months (4·5-6·8) with erlotinib (adjusted hazard ratio [HR] 0·73, 95% CI 0·53-1·00; p=0·05). Progression-free survival was significantly better with docetaxel than with erlotinib: median progression-free survival was 2·9 months (95% CI 2·4-3·8) with docetaxel versus 2·4 months (2·1-2·6) with erlotinib (adjusted HR 0·71, 95% CI 0·53-0·95; p=0·02). The most common grade 3-4 toxic effects were: low absolute neutrophil count (21 [20%] of 104 in the docetaxel group vs none of 107 in the erlotinib group), skin toxic effects (none vs 15 [14%]), and asthenia (ten [10%] vs six [6%]).

INTERPRETATION

Our results show that chemotherapy is more effective than erlotinib for second-line treatment for previously treated patients with NSCLC who have wild-type EGFR tumours.

TAILOR: A phase III trial comparing erlotinib with docetaxel as the second-line treatment of NSCLC patients with wild-type (wt) EGFR

LBA7501

Background: While the benefit of EGFR tyrosine kinase inhibitors in the treatment of patients with NSCLC harboring EGFR mutations has been widely established, their value in treating patients with wt EGFR is still debated. To assess the role of erlotinib in these patients, we performed an independent multicenter phase III trial (Tarceva Italian Lung Optimization Trial [TAILOR] NCT00637910), comparing erlotinib to docetaxel in second line treatment, having overall (OS) and progression free survival (PFS) as principal and secondary endpoints, respectively. Methods: EGFR and KRAS mutational status were assessed by direct sequencing in all eligible patients; only patients with wt EGFR NSCLC (exons 19 and 21) at progression, and previously treated with a first line platinum-based regimen, were randomized to receive either erlotinib 150 mg daily or docetaxel 75 mg/m2 (3-weekly) or 35 mg/m2 (weekly) until disease progression or unacceptable toxicity occurred. To detect an hazard ratio of 0.67 (2-sided 5% significance level for the log-rank test and a power of 80%), 199 events were required for both OS and PFS evaluation. Results: On the planned analysis date (March 30, 2012), 221 patients had been randomized and 218 were evaluable (docetaxel 110, erlotinib 108; three major violations excluded). At a median follow-up of 20 months, 199 relapses and 157 deaths were recorded. The Kaplan-Meier PFS curves showed a highly significant increase favoring docetaxel (HR 0.70 with 95% CI 0.53-0.94; p = 0.016) over erlotinib regimen. The HR translated into an estimated absolute difference in 6-months PFS of 12% (16% vs 28%). Data concerning toxicity were consistent with the literature. Conclusions: In terms of PFS, our results indicate a clear superiority of docetaxel over erlotinib as second line treatment for patients without EGFR mutations in exons 19 or 21. Analysis of OS will be conducted as far as the planned number of 199 deaths is reached.

The predictive value of clinical variables in patients affected with non-small-cell lung cancer (NSCLC) treated with pemetrexed (PEM) plus platinum-based regimen: A retrospective analysis

e18065

Background: PEM plus platinum–based regimen is a standard of care in chemonaïve advanced non-squamous NSCLC pts. This retrospective multicenter analysis was performed to evaluate the predictive value of clinical variables for PFS in an unselected population. Methods: Data were obtained by reviewing the clinical data of pts affected with advanced NSCLC treated from 2009 to 2011. 193 pts were retrieved. Main characteristics were: median age: 63 years (range 33-79); male/female (M/F): 67%/33%; ECOG PS 0-1: 97%; weight loss >5%: 34%; current smoker 31%. Stage IV disease: 81% ; ≥ 1 site of metastasis: 79%. Brain metastasis: 28% of pts at diagnosis. Results: All 193 pts are evaluable for analysis. 158 pts (82%) received the cisplatin- and 35 pts (18%) the carboplatin-based regimen. Most pts received at least 2 cycles of therapy and 21% received PEM maintenance treatment. The overall disease control rate observed was 69%. (CR+PR = 44%, SD 25%). At a median follow-up of 6.7 months (range 1-22), the median PFS was 6 months (95%CI 5-7) with a 1 year-PFS rate of 16.8%. In the Cox multivariate analysis, factors found to be associated with a statistically significant longer PFS were: gender (M vs F, HR 1.68, C.I.95% 1.19-2.38; p=0.003); no. of metastatic site (>1 vs 1, HR 1.6, 95%CI 1.07-2.40; p=0.02); type of response (CR/PR vs no response, HR 2.74, 95%CI 1.95-3.86; p<0.0001); and maintenance treatment (no vs yes, HR 2.74, 95%CI 1.95-3.86; p=0.02). The Kaplan-Meyer analysis of 1-year PFS confirmed female gender (F vs M 24.4% vs 12.2%, log-rank p=0.01), objective response (CR/PR vs SD/PD 29.9% vs 5.2%, log-rank p<0.0001), and maintenance therapy (yes vs no 30% vs 17.3%, log-rank p=0.01) as the significant clinical variables predictive of longer survival. Conclusions: According to our data only female gender, responsive disease and subsequent maintenance therapy were independent predictive factors. No difference in term of PFS outcome were found for elderly pts, presence of brain metastases and weight loss at diagnosis. Overall survival data will be presented.

Carboplatin- or cisplatin-based chemotherapy in first-line treatment of small-cell lung cancer: the COCIS meta-analysis of individual patient data

PURPOSE

Since treatment efficacy of cisplatin- or carboplatin-based chemotherapy in the first-line treatment of small-cell lung cancer (SCLC) remains contentious, a meta-analysis of individual patient data was performed to compare the two treatments.

PATIENTS AND METHODS

A systematic review identified randomized trials comparing cisplatin with carboplatin in the first-line treatment of SCLC. Individual patient data were obtained from coordinating centers of all eligible trials. The primary end point was overall survival (OS). All statistical analyses were stratified by trial. Secondary end points were progression-free survival (PFS), objective response rate (ORR), and treatment toxicity. OS and PFS curves were compared by using the log-rank test. ORR was compared by using the Mantel-Haenszel test.

RESULTS

Four eligible trials with 663 patients (328 assigned to cisplatin and 335 to carboplatin) were included in the analysis. Median OS was 9.6 months for cisplatin and 9.4 months for carboplatin (hazard ratio [HR], 1.08; 95% CI, 0.92 to 1.27; P = .37). There was no evidence of treatment difference between the cisplatin and carboplatin arms according to sex, stage, performance status, or age. Median PFS was 5.5 and 5.3 months for cisplatin and carboplatin, respectively (HR, 1.10; 95% CI, 0.94 to 1.29; P = .25). ORR was 67.1% and 66.0%, respectively (relative risk, 0.98; 95% CI, 0.84 to 1.16; P = .83). Toxicity profile was significantly different for each of the arms: hematologic toxicity was higher with carboplatin, and nonhematologic toxicity was higher with cisplatin.

CONCLUSION

Our meta-analysis of individual patient data suggests no differences in efficacy between cisplatin and carboplatin in the first-line treatment of SCLC, but there are differences in the toxicity profile.

Maintenance therapy in NSCLC: why? To whom? Which agent?

Maintenance therapy is emerging as a treatment strategy in the management of advanced non small cell lung cancer (NSCLC). Initial trials addressing the question of duration of combination chemotherapy failed to show any overall survival benefit for the prolonged administration over a fixed number of cycles with an increased risk for cumulative toxicity. Nowadays several agents with different ways of administration and a different pattern of toxicity have been formally investigated in the maintenance setting. Maintenance strategies include continuing with an agent already present in the induction regimen or switching to a different one. Taking into consideration that no comparative trials of maintenance with different chemotherapy drugs or targeted agents have been conducted, the choice and the duration of maintenance agents is largely empirical. Furthermore, it is still unknown and it remains an open question if this approach needs to be proposed to every patient in the case of partial/complete response or stable disease after the induction therapy. Here, we critically review available data on maintenance treatment, discussing the possibility to tailor the right treatment to the right patient, in an attempt to optimize costs and benefits of an ever-growing panel of different treatment options.

Clinical and molecular determinants of survival in pancreatic cancer patients treated with second-line chemotherapy: results of an Italian/Swiss multicenter survey

BACKGROUND

Increased knowledge about the treatment of pancreatic cancer has influenced the management of locally advanced and metastatic disease. Nonetheless, prognosis remains dismal (24%, 1-year survival). The impact on overall survival (OS) of second-line therapy has not been clarified and the use of platinum salts and/or fluoropyrimidines is hotly debated. It is the hope that future treatment can be tailored to predict chemosensitivity in order to improve outcomes in patients with locally advanced and metastatic pancreatic cancer. Since DNA-damaging agents could be one therapeutic option, a retrospective multicenter study was performed to evaluate the efficacy of salvage treatment with the hypothesis that levels of the DNA repair gene excision repair cross complementing 1 (ERCC1) could influence OS.

PATIENTS AND METHODS

In a population of 160 patients treated with fluoropyrimidine-based second-line chemotherapy, expression levels of ERCC1 were determined by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR). In 108 patients with locally advanced and metastatic pancreatic cancer treated with either fluoropyrimidines and platinum salts (group A=58) or fluoropyrimidines alone (group B=50), ERCC1 levels were correlated with OS, time to progression and response to chemotherapy.

RESULTS

Median survival was significantly higher in group A with low ERCC1 levels [11.9 versus 9.9 months; p ≤ 0.05] (median follow-up 24 months). Moreover in the same group, a trend towards longer time to progression was observed. No differences in OS were observed when ERCC1 was studied (low versus high) in patients not treated with platinum salts. On multivariate analysis of pretreatment prognostic factors, ERCC1 emerged as an independent predictive factor for OS.

CONCLUSION

The results of this study indicate that ERCC1 may predict survival in pancreatic cancer patients treated by platinum and fluoropyrimidine as second-line chemotherapy.

Biological and clinical features in predicting efficacy of epidermal growth factor receptor tyrosine kinase inhibitors: a systematic review and meta-analysis

BACKGROUND

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), developed for patients with advanced non-small cell lung cancer (NSCLC), give modest results similar to those with chemotherapy. There is evidence of a greater survival benefit from TKIs in patients with certain molecular and clinical features, but results are conflicting. To assess the role of these factors in predicting TKI efficacy, a pooled analysis was performed on data from randomized trials in NSCLC.

MATERIALS AND METHODS

An electronic search of all randomized trials comparing the efficacy or activity of TKIs and a pooled analysis were performed. The hazard ratio (HR) with 95% confidence interval (CI) was calculated for each level of the factors and an interaction test was used to detect differences in treatment effect related to the different levels.

RESULTS

Of ten randomized trials identified, five were considered for analysis. Smoking was shown to be the only clinical factor to have a predictive effect (non smokers: overall survival (OS) HR 0.53, 95% CI 0.42-0.67; smokers: HR 0.91, 95% CI 0.81-1.02; p-value for interaction <0.001). A negative predictive value was suggested for K-ras mutations (K-ras(+): HR 1.97 95% CI 1.16-3.33; K-ras(-): HR 0.79, 95% CI 0.59-1.05; p-value for interaction 0.003).

CONCLUSION

At the present time, none of the biological features which have been evaluated in patients who have undergone therapy using TKIs is proven to be of predictive value; only K-ras mutations and smoking habits can be considered as a possible criteria for selection. Results of prospective randomized trials on biological markers are awaited.
