Introduction: Predictors for mortality and toxicity in older patients with cancer are mainly studied in cohorts with various cancers at different stages. This study aims to identify predictive geriatric factors (PGFs) for early death and severe chemotherapy related adverse events (CRAEs) in patients aged ≥70 years with metastatic non-small-cell lung cancer (mNSCLC)., Material and Methods: This is a secondary analysis of the multicenter, randomized, phase 3 ESOGIA trial that compared, for patients ≥70 years with mNSCLC, a treatment algorithm based on performance status and age to another algorithm based on geriatric assessment. To identify PGFs of three-month mortality and grade 3, 4, or 5 CRAEs, multivariate Cox models and logistic models, adjusted for treatment group and center, and stratified by randomization arm, were constructed., Results: Among 494 included patients, 145 (29.4%) had died at three months and 344 (69.6%) had severe chemotherapy toxicity. For three-month mortality, multivariate analyses retained mobility (Test Get up and Go), instrumental activity of daily living (IADL) dependence and weight loss as PGFs. The combined effect of IADL ≤2/4 and weight loss ≥3 kg was strongly associated with three-month mortality (adjusted hazard ratio: 5.71 [95% confidence interval [CI]: 2.64-12.32]). For chemotherapy toxicity, Charlson Comorbidity Index ≥2 was independently associated with grade3, 4, or 5 CRAEs (adjusted odds ratio [95% CI]: 1.94 [1.06-3.56])., Discussion: Mobility, IADL dependence, and weight loss were predictive of three-month mortality in a population aged ≥70 years treated for mNSCLC, while comorbidities were independently associated with severe chemotherapy toxicity., Competing Interests: Declaration of Competing Interest All authors have no conflicts of interest and disclosures., (Copyright © 2023.

Background: Pleural mesothelioma usually presents at an advanced, incurable stage. Chemotherapy with platinum-pemetrexed is a standard treatment. We hypothesised that the addition of pembrolizumab to platinum-pemetrexed would improve overall survival in patients with pleural mesothelioma., Methods: We did this open-label, international, randomised phase 3 trial at 51 hospitals in Canada, Italy, and France. Eligible participants were aged 18 years or older, with previously untreated advanced pleural mesothelioma, with an Eastern Cooperative Oncology Group performance status score of 0 or 1. Patients were randomly assigned (1:1) to intravenous chemotherapy (cisplatin [75 mg/m 2 ] or carboplatin [area under the concentration-time curve 5-6 mg/mL per min] with pemetrexed 500 mg/m 2 , every 3 weeks for up to 6 cycles), with or without intravenous pembrolizumab 200 mg every 3 weeks (up to 2 years). The primary endpoint was overall survival in all randomly assigned patients; safety was assessed in all randomly assigned patients who received at least one dose of study therapy. This trial is registered with ClinicalTrials.gov, NCT02784171, and is closed to accrual., Findings: Between Jan 31, 2017, and Sept 4, 2020, 440 patients were enrolled and randomly assigned to chemotherapy alone (n=218) or chemotherapy with pembrolizumab (n=222). 333 (76 %) of patients were male, 347 (79%) were White, and median age was 71 years (IQR 66-75). At final analysis (database lock Dec 15, 2022), with a median follow-up of 16·2 months (IQR 8·3-27·8), overall survival was significantly longer with pembrolizumab (median overall survival 17·3 months [95% CI 14·4-21·3] with pembrolizumab vs 16·1 months [13·1-18·2] with chemotherapy alone, hazard ratio for death 0·79; 95% CI 0·64-0·98, two-sided p=0·0324). 3-year overall survival rate was 25% (95% CI 20-33%) with pembrolizumab and 17% (13-24%) with chemotherapy alone. Adverse events related to study treatment of grade 3 or 4 occurred in 60 (27%) of 222 patients in the pembrolizumab group and 32 (15%) of 211 patients in the chemotherapy alone group. Hospital admissions for serious adverse events related to one or more study drugs were reported in 40 (18%) of 222 patients in the pembrolizumab group and 12 (6%) of 211 patients in the chemotherapy alone group. Grade 5 adverse events related to one or more drugs occurred in two patients on the pembrolizumab group and one patient in the chemotherapy alone group., Interpretation: In patients with advanced pleural mesothelioma, the addition of pembrolizumab to standard platinum-pemetrexed chemotherapy was tolerable and resulted in a significant improvement in overall survival. This regimen is a new treatment option for previously untreated advanced pleural mesothelioma., Funding: The Canadian Cancer Society and Merck & Co., Competing Interests: Declaration of interests MP has received grants for research to institution from AstraZeneca and Roche; payment for educational events from Astellas, Pfizer, and AstraZeneca; and received drugs for research from Roche and AstraZeneca.

Purpose: The COVID-19 vaccination campaign began in December 2020, in France, and primarily targeted the oldest people. Our study aimed to determine the level of acceptance of vaccination in a population of older patients with cancer., Methods: From January 2021, we offered vaccination with the BNT162b2 COVID-19 vaccine to all patients 70 years and older referred to our geriatric oncology center in Marseille University Hospital (AP-HM) for geriatric assessment before initiation of an oncological treatment. Objectives were to evaluate acceptance rate of COVID-19 vaccination and to assess vaccine safety, reactogenicity, and efficacy two months after the first dose., Results: Between January 18, 2021 and May 7, 2021, 150 older patients with cancer were offered vaccination after a geriatric assessment. The majority were men (61.3%), with a mean age of 81 years. The two most frequent primary tumors were digestive (29.4%) and thoracic (18%). The vaccine acceptance rate was 82.6% and the complete vaccination rate (2 doses) reached 75.3%. Among the vaccinated patients, 15.9% reported mild side effects after the first dose and 23.4% after the second dose, mostly arm pain and fatigue. COVID-19 cases were observed in 5.1% of vaccinated patients compared with 16.7% in unvaccinated patients. Of the 22 vaccinated patients who agreed to have their serum tested, 15 had antibodies against the spike protein at day 21 after the first dose., Conclusion: Our study showed a high acceptance rate of COVID-19 vaccination, with good tolerance in this frail population. These results highlight the benefits of organizing vaccination campaigns at the very beginning of oncological management in older patients., Clinical Trial Registration: This study was registered May 23, 2019 in ClinicalTrials.gov (NCT03960593)., (Copyright © 2022 Elsevier Ltd.

Thymic epithelial tumors are rare neoplastic proliferations of thymic epithelial cells. The aggressiveness of these malignancies increases as higher is the histologic subtype, being thymic carcinoma the most aggressive subtype, with a greater tendency to metastatic spread. In metastatic setting, there is no standard treatment after progression on platinum-based chemotherapy. In this scenario, monotherapy treatment either with lenvatinib, a multi-tyrosine kinase inhibitor with antiangiogenic properties, or pembrolizumab, an immune-checkpoint inhibitor, has reported clinical activity. Potential combination of both agents may have synergistic activity as reported in other cancer types. PECATI trial is a single-arm, investigator-initiated phase II study aiming to assess the activity and safety of the combination of lenvatinib and pembrolizumab in 43 patients with advanced B3-thymoma or thymic carcinoma who progressed on or after at least one previous line of platinum-based chemotherapy. The primary endpoint of the trial is 5-month progression-free survival rate and the secondary endpoints include overall response rate, duration of response, and overall survival., Competing Interests: Disclosure The authors have stated that they have no conflicts of interest., (Copyright © 2021.

Background: Functional Status (FS) is an important domain in Comprehensive Geriatric Assessment (CGA) and is most often evaluated using the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales separately., Method and Objectives: This secondary analysis of a previous prospective cohort study was conducted between September 2015 and May 2018 at Marseille University Hospital, France, on 613 cancer outpatients aged ≥70 years. The first objective of this study was to determine the prevalence of FS impairment in older outpatients with cancer using a combination of the information collected with the ADL and short IADL scales. Our second objective was to describe the potential impact of this combined FS on three-month unplanned hospitalizations and three-month mortality in this population., Results: The median age was 81 years and 61.2% were men. The most common types of tumours were lung and thoracic (22.3%). Concerning FS, 255 patients (41.6%) had unimpaired ADL-IADL, 131 patients (21.4%) had IADL impairment, 38 patients (6.2%) had ADL impairment, and 189 patients (30.8%) had impaired ADL-IADL. In the multivariate Cox analysis, metastatic stage (adjusted Hazard Ratio (aHR) = 1.79; 95% CI [1.14-2.80]) and impaired ADL-IADL (aHR = 3.46; 95% CI [1.89-6.33]) were independently associated with three-month mortality. In the logistic regression model, impaired ADL-IADL (adjusted Odd ratio (aOR) = 3.64; 95% CI [1.84-7.20]) was the only factor independently associated with three-month unplanned hospitalizations., Interpretation: The combined use of the ADL and IADL scales to evaluate functional status in older patients with cancer is of significant prognostic value regarding the risks of three-month unplanned hospitalizations and mortality., Competing Interests: Declaration of Competing Interest None of the authors have any conflicts of interest to disclose., (Copyright © 2021 Elsevier Ltd.

Introduction: This open-label, phase 1-2 study evaluated the safety and efficacy of rovalpituzumab tesirine (Rova-T), an antibody-drug conjugate targeting DLL3, plus immune checkpoint inhibitors nivolumab plus or minus ipilimumab in previously treated extensive-stage SCLC (ES SCLC)., Methods: Patients with histologically or cytologically confirmed, previously treated (two or more lines of therapy) ES SCLC were enrolled into two cohorts. Cohort 1 received 0.3 mg/kg Rova-T (once every 6 wk for two cycles) plus 360 mg nivolumab (two 3-wk cycles beginning on week 4). Cohort 2 received the same dosage of Rova-T as cohort 1 plus 1 mg/kg nivolumab (four 3-wk cycles) and 1 mg/kg ipilimumab (beginning week 4). Both cohorts received 480 mg nivolumab every 4 weeks starting at week 10. Key objectives were to evaluate safety and tolerability and efficacy (per Response Evaluation Criteria in Solid Tumors version 1.1). The response-related results are based on centrally read data., Results: A total of 42 patients received therapy: cohort 1, n = 30; cohort 2, n = 12. Overall, 43% received two or more previous lines of therapy. All patients experienced one or more treatment-emergent adverse event (TEAE); 41 patients reported AEs considered related to the study drug by the investigator. The most frequent TEAE was pleural effusion (n = 20, 48%); most common grade greater than or equal to 3 was anemia (n = 9, 21%). Three grade 5 TEAEs considered related to the study drug were reported (cohort 1): pneumonitis (n = 2), acute kidney injury (n = 1). The objective response rate was 30% (12 of 40): cohort 1, 27.6% (8 of 29); cohort 2, 36.4% (4 of 11); all partial responses., Conclusions: Despite encouraging antitumor activity in previously treated ES SCLC, combination therapy with Rova-T and nivolumab plus or minus ipilimumab was not well tolerated at the dose levels and administration schedules evaluated., (Copyright © 2021 International Association for the Study of Lung Cancer.

Introduction: DLL3, an atypical Notch ligand, is expressed in SCLC tumors but is not detectable in normal adult tissues. Rovalpituzumab tesirine (Rova-T) is an antibody-drug conjugate containing a DLL3-targeting antibody tethered to a cytotoxic agent pyrrolobenzodiazepine by means of a protease-cleavable linker. The efficacy and safety of Rova-T compared with topotecan as second-line therapy in patients with SCLC expressing high levels of DLL3 (DLL3-high) was evaluated., Methods: The TAHOE study was an open-label, two-to-one randomized, phase 3 study comparing Rova-T with topotecan as second-line therapy in DLL3-high advanced or metastatic SCLC. Rova-T (0.3 mg/kg) was administered intravenously on day 1 of a 42-day cycle for two cycles, with two additional cycles available to patients who met protocol-defined criteria for continued dosing. Topotecan (1.5 mg/m 2 ) was administered intravenously on days 1 to 5 of a 21-day cycle. The primary end point was overall survival (OS)., Results: Patients randomized to Rova-T (n = 296) and topotecan (n = 148) were included in the efficacy analyses. The median age was 64 years, and 77% had the extensive disease at initial diagnosis. The median OS (95% confidence interval) was 6.3 months (5.6-7.3) in the Rova-T arm and 8.6 months (7.7-10.1) in the topotecan arm (hazard ratio, 1.46 [95% confidence interval: 1.17-1.82]). An independent data monitoring committee recommended that enrollment be discontinued because of the shorter OS observed with Rova-T compared with topotecan. Safety profiles for both drugs were consistent with previous reports., Conclusions: Compared with topotecan, which is the current standard second-line chemotherapy, Rova-T exhibited an inferior OS and higher rates of serosal effusions, photosensitivity reaction, and peripheral edema in patients with SCLC. A considerable unmet therapeutic need remains in this population., (Copyright © 2021 International Association for the Study of Lung Cancer. Published by Elsevier Inc. All rights reserved.)

Background: Lung cancer affects older adults and is the leading solid tumor in terms of death. A Comprehensive Geriatric Assessment (CGA) is recommended before cancer treatment to guide therapy management., Patients and Methods: This study was conducted between September 2015 and January 2019. During this period of time, all consecutive older outpatients referred for a CGA before initiation of lung or thoracic tumor treatment were included. The objectives were to describe the impact of geriatric factors on unplanned hospitalizations and overall survival (OS). The study was approved by a local ethics committee., Results: Overall, 228 patients were recruited. The median age was 78.7 ± 5 years. The majority (82%) of patients were diagnosed with non-small-cell lung cancer, and the most common (40.4%) treatment was systemic therapy. In multivariate analysis, factors associated with unplanned hospitalizations within the first 3 months were male gender (adjusted odds ratio [aOR], 3.3; 95% confidence interval [CI], 1.5-7.2), systemic therapy (aOR, 2.6; 95% CI, 1.1-6.2), and fall history (aOR, 3.6; 95% CI, 1.6-8.2). Factors associated with a decrease in OS in the multivariate Cox model analysis were male gender (hazard ratio [HR], 3.9; 95% CI, 2.1-7.3), stage IV (HR, 1.6; 95% CI, 1.0-2.6), G8 ≤ 14 (HR, 3.5; 95% CI, 1.1-11.4), systemic therapy (HR, 2.6; 95% CI, 1.2-5.5), Eastern Cooperative Oncology Group performance status ≥ 2 (HR, 2.0; 95% CI, 1.2-3.4), and impaired handgrip strength (HR, 1.6; 95% CI, 1.0-2.5)., Conclusion: G8 score and handgrip strength are important to predict OS in older adults treated for thoracic tumors. In the CGA, fall history was associated with unplanned hospitalization., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Lung cancer affects older and older old adults and is the leading cause of death by cancer. Comprehensive Geriatric Assessment (CGA) is recommended before and during cancer treatment to guide therapy management in this population., Methods: This study was conducted between September 2015 and January 2019 at Marseille University Hospital (AP-HM). During this period, all consecutive outpatients 70 years or older referred for a CGA before initiation of lung cancer treatment were enrolled. The objective of this study was to compare lung and thoracic cancer management of octogenarians (≥80 years) and their geriatric profile versus patients aged 70 to 79 years (<80 years)., Findings: In our study, 228 patients were recruited. The median age was 78.7 ± 5 years. There were 94 octogenarians (41.2%), 36.2% of them were diagnosed with stage IV neoplasm and the most common treatment was chemotherapy (43.6%). The logistic regression analysis highlights that handgrip strength was the most commonly impaired domain (OR 2.3; 95% CI [1.3-4.3]) in octogenarians and that they are more likely than their younger counterparts to be treated by targeted therapy (OR 9.8; 95% CI [1.0-92.9]). Overall survival (OS) was similar in both age groups (log rank = 0,95)., Interpretation: In our study, octogenarians and patients <80 years had equivalent survival, across the different thoracic cancer treatments and tumor stages. Measure of muscle strength in CGA could be very useful in a clinical setting to help improve the management of older old patients treated for lung or thoracic cancer., Competing Interests: Declaration of Competing Interest None of the authors have conflict of interest to declare., (Copyright © 2020 Elsevier Inc.

Background: Approved systemic treatments for malignant pleural mesothelioma (MPM) have been limited to chemotherapy regimens that have moderate survival benefit with poor outcomes. Nivolumab plus ipilimumab has shown clinical benefit in other tumour types, including first-line non-small-cell lung cancer. We hypothesised that this regimen would improve overall survival in MPM., Methods: This open-label, randomised, phase 3 study (CheckMate 743) was run at 103 hospitals across 21 countries. Eligible individuals were aged 18 years and older, with previously untreated, histologically confirmed unresectable MPM, and an Eastern Cooperative Oncology Group performance status of 0 or 1. Eligible participants were randomly assigned (1:1) to nivolumab (3 mg/kg intravenously once every 2 weeks) plus ipilimumab (1 mg/kg intravenously once every 6 weeks) for up to 2 years, or platinum plus pemetrexed chemotherapy (pemetrexed [500 mg/m 2 intravenously] plus cisplatin [75 mg/m 2 intravenously] or carboplatin [area under the concentration-time curve 5 mg/mL per min intravenously]) once every 3 weeks for up to six cycles. The primary endpoint was overall survival among all participants randomly assigned to treatment, and safety was assessed in all participants who received at least one dose of study treatment. This study is registered with ClinicalTrials.gov, NCT02899299, and is closed to accrual., Findings: Between Nov 29, 2016, and April 28, 2018, 713 patients were enrolled, of whom 605 were randomly assigned to either nivolumab plus ipilimumab (n=303) or chemotherapy (n=302). 467 (77%) of 605 participants were male and median age was 69 years (IQR 64-75). At the prespecified interim analysis (database lock April 3, 2020; median follow-up of 29·7 months [IQR 26·7-32·9]), nivolumab plus ipilimumab significantly extended overall survival versus chemotherapy (median overall survival 18·1 months [95% CI 16·8-21·4] vs 14·1 months [12·4-16·2]; hazard ratio 0·74 [96·6% CI 0·60-0·91]; p=0·0020). 2-year overall survival rates were 41% (95% CI 35·1-46·5) in the nivolumab plus ipilimumab group and 27% (21·9-32·4) in the chemotherapy group. Grade 3-4 treatment-related adverse events were reported in 91 (30%) of 300 patients treated with nivolumab plus ipilimumab and 91 (32%) of 284 treated with chemotherapy. Three (1%) treatment-related deaths occurred in the nivolumab plus ipilimumab group (pneumonitis, encephalitis, and heart failure) and one (<1%) in the chemotherapy group (myelosuppression)., Interpretation: Nivolumab plus ipilimumab provided significant and clinically meaningful improvements in overall survival versus standard-of-care chemotherapy, supporting the use of this first-in-class regimen that has been approved in the USA as of October, 2020, for previously untreated unresectable MPM., Funding: Bristol Myers Squibb., (Copyright © 2021 Elsevier Ltd.

Immunotherapy by immune check-points inhibitors (ICIs) recently improved many solid tumors survival data. ICIs target and inhibit down-regulation signals between T cells and tumor cells involved in carcinogenesis, in order to enhance anti-tumor immunity. With few years' hindsight of ICIs utilization in daily practice, we learned about their safety profile. By releasing the brakes of the host immune-system, ICIs exposure leads to on-target off-tumor immune related adverse events (IRAEs). Compared to standard chemotherapiy regimens, IRAEs remain rare, but sometimes serious and compromising treatment continuation, mostly despite objective tumor response. Several immunotherapy molecules are currently developed, with various mechanisms of action but always targeting the immune anti-tumor response. New drugs imply new safety profiles, especially since a lot of ongoing clinical trials are assessing combination of multiples drugs. Consequently, a good knowledge and management of these new toxicities will be essential to choose the new therapeutic schedules in many tumor types. Indeed, despite the actual poor prognosis of concerned tumor types, the progressive outcomes improvement implies long-term exposure to treatments. Safety and quality of life under treatment will become key endpoints for therapeutic decision., (Copyright © 2020 Société Française du Cancer. Published by Elsevier Masson SAS. All rights reserved.)

Introduction: Improved outcome has been shown in patients with synchronous oligometastatic (sOM) NSCLC when treated with radical intent. As a uniform definition of sOM NSCLC is lacking, we developed a definition and diagnostic criteria by a consensus process., Methods: A pan-European multidisciplinary consensus group was established. Consensus questions were built on the basis of current controversies, and definitions were extracted from a survey, cases and a systematic review. This statement was formulated during a consensus meeting., Results: It was determined that definition of sOM NSCLC is relevant when a radical treatment that may modify the disease course (leading to long-term disease control) is technically feasible for all tumor sites with acceptable toxicity. On the basis of the review, a maximum of five metastases and three organs was proposed. Mediastinal lymph node involvement was not counted as a metastatic site. Fludeoxyglucose F 18 positron emission tomography-computed tomography and brain imaging were considered mandatory. A dedicated liver magnetic resonance imaging scan was advised for a solitary liver metastasis, and thoracoscopy and biopsies of distant ipsilateral pleural sites were recommended for a solitary pleural metastasis. For mediastinal staging, fludeoxyglucose F 18 positron emission tomography-computed tomography was deemed the minimum requirement, with pathological confirmation recommended if this influences the treatment strategy. Biopsy of a solitary metastatic location was mandated unless the multidisciplinary team is of the opinion that the risks outweigh the benefits., Conclusion: A multidisciplinary consensus statement on the definition and staging of sOM NSCLC has been formulated. This statement will help to standardize inclusion criteria in future clinical trials., (Copyright © 2019 International Association for the Study of Lung Cancer. Published by Elsevier Inc.

Background: Anticancer immune responses are negatively regulated by programmed cell death 1 (PD-1) T-cell membrane protein interaction with its ligand, programmed death ligand 1 (PD-L1), on cancer cells. We sought to assess the prognostic role of PD-L1 expression in tumor samples from patients enrolled onto the IFCT-0701 MAPS randomized phase 3 trial (NCT00651456)., Patients and Methods: Tumor samples were analyzed by immunohistochemistry for percentages of PD-L1 membrane-stained tumor cells using the E1L3N clone, and data were correlated to survival by multivariate Cox models including stratification variables., Results: PD-L1 staining was assessed in 214 (47.75%) of 448 patients. Epithelioid subtype represented 83.7% (179/214). Absence of PD-L1 staining occurred in 137 (64.1%) of 214 malignant pleural mesothelioma (MPM) samples, while 77 (35.9%) of 214 were PD-L1 positive, with 50 (64.9%) of 77 showing < 50% PD-L1-expressing tumor cells. Sarcomatoid/biphasic subtypes were more commonly PD-L1 positive than epithelioid subtype (P < .001). In patients with 1% or more PD-L1-stained tumor cells, median overall survival (OS) was 12.3 months versus 22.2 months for other patients (hazard ratio [HR] = 1.25; 95% confidence interval [CI], 0.93-1.67; P = .14). OS did not differ according to PD-L1 positivity in multivariate analyses (adjusted HR = 1.10; 95% CI, 0.81-1.49; P = .55). With a 50% cutoff, PD-L1-positive patients displayed a 10.5 months median OS versus 19.3 months for patients with lower PD-L1 expression (HR = 1.93; 95% CI, 1.27-2.93; P = .002). OS did not significantly differ in adjusted Cox models (adjusted HR = 1.20; 95% CI, 0.74-1.94; P = .47). In the 179 epithelioid MPM patients, high PD-L1 staining (≥ 50% of tumor cells) negatively affected OS, although not significantly, showing a 12.3-month median OS (95% CI, 4.3-21.6) versus 23-month (95% CI, 18.5-25.2) for patients with tumor PD-L1 staining in < 50% cells (P = .071). The progression-free survival (PFS) differences were statistically significant, with a longer 9.9-month median PFS in patients with low PD-L1 staining (< 50% cells) compared to 6.7 months of median PFS in patients with high PD-L1 expression (≥ 50% cells) (P = .0047)., Conclusion: Although high PD-L1 tumor cell expression was associated with poorer OS in MPM patients from the MAPS trial, its prognostic influence was lost in multivariate analyses in the whole cohort, while PD-L1 expression was strongly associated with the sarcomatoid/biphasic subtypes. In the epithelioid MPM subset of patients, high PD-L1 tumor expression (≥ 50%) negatively affected OS and PFS, with this prognostic influence remaining statistically significant for PFS after adjustment in multivariate Cox model., (Copyright © 2019 Elsevier Inc.

Introduction: KRAS mutation is the most frequent molecular alteration found in advanced NSCLC; it is associated with a poor prognosis without available targeted therapy. Treatment options for NSCLC have been recently enriched by the development of immune checkpoint inhibitors (ICIs), and data about its efficacy in patients with KRAS-mutant NSCLC are discordant. This study assessed the routine efficacy of ICIs in advanced KRAS-mutant NSCLC., Methods: In this retrospective study, clinical data were extracted from the medical records of patients with advanced NSCLC treated with ICIs and with available molecular analysis between April 2013 and June 2017. Analysis of programmed death ligand 1 (PD-L1) expression was performed if exploitable tumor material was available., Results: A total of 282 patients with ICI-treated (in the first line or more) advanced NSCLC (all histological subgroups) who were treated with ICIs (anti-programmed death 1, anti-PD-L1, or anti-cytotoxic T-lymphocyte associated protein 4 antibodies), including 162 (57.4%) with KRAS mutation, 27 (9.6%) with other mutations, and 93 (33%) with a wild-type phenotype, were identified. PD-L1 analysis was available for 128 patients (45.4%), of whom 45.3% and 19.5% had PD-L1 expression of 1% or more and 50%, respectively (49.5% and 21.2%, respectively, in the case of the 85 patients with KRAS-mutant NSCLC). No significant difference was seen in terms of objective response rates, progression-free survival, or overall survival between KRAS-mutant NSCLC and other NSCLC. No significant differences in overall survival or progression-free survival were observed between the major KRAS mutation subtypes (G12A, G12C, G12D, G12V, and G13C). In KRAS-mutant NSCLC, unlike in non-KRAS-mutant NSCLC, the efficacy of ICIs is consistently higher, even though not statistically significant, for patients with PD-L1 expression in 1% or more of tumor cells than for those with PD-L1 expression in less than 1% of tumor cells, and this finding is especially true when PD-L1 expression is high (PD-L1 expression ≥50%)., Conclusion: For patients with KRAS-mutant NSCLC (all mutational subtypes), the efficacy of ICI is similar to that for patients with other types of NSCLC. PD-L1 expression seems to be more relevant for predicting the efficacy of ICIs in KRAS-mutant NSCLC than it is in other types of NSCLC., (Copyright © 2019 International Association for the Study of Lung Cancer.

Introduction: This randomized phase II trial aimed at evaluating the engineered programmed cell death ligand 1 (PD-L1) antibody atezolizumab in SCLC progressing after first-line platinum-etoposide chemotherapy., Methods: Patients were randomized 2:1 to atezolizumab (1200 mg intravenously every 3 weeks) until progression or unacceptable toxicity, or conventional chemotherapy (up to 6 cycles of topotecan or re-induction of initial chemotherapy). Patients were not selected based on PD-L1 tissue expression. The primary endpoint was objective response rate at 6 weeks. A two-stage design with 2:1 randomization and O'Brien-Fleming stopping rules was used. The null hypothesis was rejected if more than 12 of 45 patients were responders., Results: Overall, 73 patients were randomized (atezolizumab n = 49; chemotherapy n = 24). At 6 weeks, 1 of 43 eligible atezolizumab patients achieved an objective response (2.3%, 95% confidence interval [CI]: 0.0-6.8), whereas 8 others had stable disease (20.9% disease control rate; 95% CI: 8.8-33.1). Among eligible chemotherapy patients (n = 20), 10% achieved an objective response (65% disease control rate). Median progression-free survival was 1.4 months (95% CI: 1.2-1.5) with atezolizumab and 4.3 months (95% CI: 1.5-5.9) with chemotherapy. Overall survival did not significantly differ between groups. Median overall survival was 9.5 months versus 8.7 months for the atezolizumab and the chemotherapy group, respectively (adjusted hazard ratio atezolizumab : 0.84, 95% CI: 0.45-1.58; p = 0.60). Two atezolizumab patients (4.2%) experienced grade 3 fatigue, and two others grade 1 dysthyroidism. Among 53 evaluable specimens, only 1 (2%) had positive immunohistochemical PD-L1 staining (SP142 clone)., Conclusions: Atezolizumab monotherapy in relapsed SCLC failed to show significant efficacy. No unexpected safety concerns were observed., (Copyright © 2019 International Association for the Study of Lung Cancer. Published by Elsevier Inc. All rights reserved.)

Background: Immune checkpoint inhibitors (ICIs) are available for first- and further lines of treatment of patients with advanced non-small-cell lung cancer (NSCLC). These treatments are associated with adverse events called immune-related adverse events (IRAEs). The incidence, diagnosis, and treatment of IRAEs are quite acknowledged; however, the link between IRAEs and the efficacy of ICIs requires further clarification. The objectives of this study were to assess the association between IRAEs incidence and severity and ICIs efficacy in patients with advanced NSCLC., Methods: In this retrospective study, clinical, biological, treatment, and outcome data were collected from patients with advanced NSCLC who received at least 1 cycle of ICIs from April 2013 to February 2017. The primary endpoint was to assess the association of IRAEs incidence with overall survival (OS). Secondary endpoints were the association of IRAEs with progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR)., Results: Overall, 270 patients were studied. The median OS was 14 months, median PFS was 2.6 months, ORR was 13%, and DCR was 51%. OS, PFS, and ORR were significantly better for patients with IRAEs compared with patients with no IRAEs, translating to median OS not reached versus 8.21 months, respectively (hazard ratio, 0.29; 95% confidence interval [CI], 0.18-0.46; P < .001); PFS was 5.2 versus 1.97 months (hazard ratio, 0.42; 95% CI, 0.32-0.57; P < .001); and ORR was 212.9% versus 5.7% (odds ratio, 4.9; 95% CI, 2.18-11.05; P < .001)., Conclusions: This report presents the largest case series showing longer OS and PFS and better ORR when IRAEs occurred in a population of patients with advanced NSCLC treated with ICIs. The biological background for this phenomenon is being explored prospectively., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Introduction: Thymic epithelial tumors (TETs) are rare malignancies that may be aggressive and difficult to treat. In the advanced setting, systemic treatments may be delivered as primary therapy before surgery or definitive radiotherapy, as exclusive treatment when no focal treatment is feasible, or in the setting of recurrences. Réseau tumeurs THYMIques et Cancer (RYTHMIC) is the nationwide network for TETs in France. The objective of the study was to describe the modalities and analyze the efficacy of systemic treatments for patients with advanced TETs included in the RYTHMIC prospective database hosted by the French Thoracic Cancer Intergroup., Methods: All consecutive patients for whom systemic treatment was discussed at the RYTHMIC multidisciplinary tumor board from 2012 to 2015 and who received at least one cycle of treatment were included. The main end points were objective response and progression-free survival (PFS)., Results: A total of 236 patients were included in this analysis. Of those 236 patients, 91 received primary chemotherapy, leading to response rates of 83% for thymomas and 75% for thymic carcinomas and a median PFS of 23.2 months. A strong predictor of longer PFS was histologic type of thymoma (p < 0.001). Exclusive chemotherapy was delivered to 54 patients. The response rates were 31% for thymomas and 37% for thymic carcinomas. The median PFS was 6.2 months, and it was correlated to response rate (p = 0.001). Systemic therapy for a first, second, third, and fourth recurrence was delivered to 114, 81, 51, and 27 patients, respectively. The response rates ranged between 15% and 39% for thymomas and 4% to 21% for thymic carcinomas. The median PFS times were 7.7, 6.2, 5.9, and 6.5 months, respectively., Conclusion: Patients with advanced thymic malignancies may receive multiple lines of systemic therapy, with an opportunity for clinically relevant PFS rates for which objective response may be a surrogate. Our real-life study provides landmark efficacy data that are needed when designing clinical trials to assess innovative agents., (Copyright © 2018 International Association for the Study of Lung Cancer.

Background: Lung cancer (LC) screening (LCS) with annual low-dose computed tomography scans has been seen to reduce the specific and overall mortality in selected populations. However, participation is key to successful screening programs. The EDIFICE (etude sur le dépistage des cancers et ses facteurs de compliance [survey on cancer screening and compliance factors]) nationwide observational surveys are used to assess behavior related to cancer screening programs in France., Materials and Methods: Using comprehensive multivariate stepwise logistic regression analyses of data from current and former cigarette smokers, we sought to identify the explanatory factors associated with the intention to participate in an LCS program., Results: Of the 1463 respondents with no personal history of cancer, 263 (36.4%) of the current cigarette smokers and 170 (26.3%) of the former cigarette smokers stated their willingness to participate in an LCS program. The explanatory factors differed between current cigarette smokers (already screened for LC: odds ratio [OR], 2.81; < 30 pack-years: OR, 2.69; intention to quit smoking: OR, 1.96; no social vulnerability: OR, 2.15) and former cigarette smokers (comorbidities: OR, 0.31). The usual eligibility criteria were not significantly explanatory., Conclusion: Our findings highlight the discrepancy that exists between target populations and individuals who actually intend to participate in a screening program for LC, with subsequent potential effects on the participation rates and, thus, on the efficacy of screening., (Copyright © 2018 Elsevier Inc.

Introduction: In the context of bronchial cancers, the brain is one of the most frequent sites for metastases. Local treatments of these metastases have evolved and are often combined to obtain greater efficiency, while the main objective remains to reduce the symptoms. Radiosurgery is currently used as a primary option for patients harboring few numbers of small to middle-sized brain metastases. In nonsquamous non-small cell lung cancer (NSCLC), chemotherapy is often associated with bevacizumab. Our goal was to assess the safety of this early combination., Clinical Practice Points: Six patients with advanced nonsquamous NSCLC were treated with radiosurgery for the management of their brain metastases (n = 40), followed within <4 weeks by a treatment with bevacizumab. No systemic or cerebral adverse event of grade 3 (intratumoral or parenchymal hemorrhage) or unexpected toxicity secondary to bevacizumab has been indexed., Conclusion: Radiosurgery may be safely combined with bevacizumab quite early on for patients with nonsquamous NSCLC with brain metastases., (Copyright © 2017 Elsevier Inc.

Accessibility to cancer screening in France has been facilitated by the implementation of organised programs (breast cancer and colorectal cancer) and by national recommendations (cervical cancer). Personal motivation may also trigger participation in prostate cancer screening. This paper proposes an overview of attitudes toward cancer screening among the general population over a period of more than 10 years and the perception of this behaviour by general practitioners. It is noteworthy that although certain cancer screening programmes, such as for breast cancer, are widely established throughout the population, uptake of others, such as for colorectal or prostate cancer, is contingent on sociological factors and vulnerability. Monitoring of compliance is thus all the more important since participation may be more acutely affected by the impact of social conditions and vulnerability in the current critical economic climate., (Copyright © 2016 Société Française du Cancer.

Background: Malignant pleural mesothelioma is an aggressive cancer with poor prognosis, linked to occupational asbestos exposure. Vascular endothelial growth factor is a key mitogen for malignant pleural mesothelioma cells, therefore targeting of vascular endothelial growth factor might prove effective. We aimed to assess the effect on survival of bevacizumab when added to the present standard of care, cisplatin plus pemetrexed, as first-line treatment of advanced malignant pleural mesothelioma., Methods: In this randomised, controlled, open-label, phase 3 trial, we recruited patients aged 18-75 years with unresectable malignant pleural mesothelioma who had not received previous chemotherapy, had an Eastern Cooperative Oncology Group performance status of 0-2, had no substantial cardiovascular comorbidity, were not amenable to curative surgery, had at least one evaluable (pleural effusion) or measurable (pleural tumour solid thickening) lesion with CT, and a life expectancy of >12 weeks from 73 hospitals in France. Exclusion criteria were presence of central nervous system metastases, use of antiaggregant treatments (aspirin ≥325 mg per day, clopidogrel, ticlopidine, or dipyridamole), anti-vitamin K drugs at a curative dose, treatment with low-molecular-weight heparin at a curative dose, and treatment with non-steroidal anti-inflammatory drugs. We randomly allocated patients (1:1; minimisation method used [random factor of 0·8]; patients stratified by histology [epithelioid vs sarcomatoid or mixed histology subtypes], performance status score [0-1 vs 2], study centre, or smoking status [never smokers vs smokers]) to receive intravenously 500 mg/m(2) pemetrexed plus 75 mg/m(2) cisplatin with (PCB) or without (PC) 15 mg/kg bevacizumab in 21 day cycles for up to six cycles, until progression or toxic effects. The primary outcome was overall survival (OS) in the intention-to treat population. Treatment was open label. This IFCT-GFPC-0701 trial is registered with ClinicalTrials.gov, number NCT00651456., Findings: From Feb 13, 2008, to Jan 5, 2014, we randomly assigned 448 patients to treatment (223 [50%] to PCB and 225 [50%] to PC). OS was significantly longer with PCB (median 18·8 months [95% CI 15·9-22·6]) than with PC (16·1 months [14·0-17·9]; hazard ratio 0·77 [0·62-0·95]; p=0·0167). Overall, 158 (71%) of 222 patients given PCB and 139 (62%) of 224 patients given PC had grade 3-4 adverse events. We noted more grade 3 or higher hypertension (51 [23%] of 222 vs 0) and thrombotic events (13 [6%] of 222 vs 2 [1%] of 224) with PCB than with PC., Interpretation: Addition of bevacizumab to pemetrexed plus cisplatin significantly improved OS in malignant pleural mesothelioma at the cost of expected manageable toxic effects, therefore it should be considered as a suitable treatment for the disease., Funding: Intergroupe Francophone de Cancérologie Thoracique (IFCT)., (Copyright © 2016 Elsevier Ltd.

Introduction: Malignant pleural mesothelioma (MPM) grows aggressively within the thoracic cavity and has a very low cure rate, thus highlighting the need for identification of new therapeutic targets. Adrenomedullin (AM) is a multifunctional peptide that is highly expressed in several tumors and plays an important role in angiogenesis and tumor growth after binding to its receptors, calcitonin receptor-like receptor/receptor activity-modifying protein 2 (CLR/RAMP2) and calcitonin receptor-like receptor/receptor activity-modifying protein 3 (CLR/RAMP3)., Methods: Real time quantitative reverse transcriptase polymerase chain reaction (RT-PCR) was used to assess the steady-state levels of AM, CLR, RAMP2 and RAMP3 messenger RNA (mRNA) transcripts in normal pleural tissue (n=5) and MPM (n=24). The expression of these candidates at protein level was revealed by immunohistochemistry. We also characterized the expression and regulation by hypoxia of AM system in MPM cell lines and MeT-5A cells. In vitro and in vivo studies were performed to determine the functional role of AM system in MPM., Results: In this study, real-time quantitative reverse transcriptase polymerase chain reaction showed twofold to 10-fold higher levels of AM messenger RNA in MPM tissue than in normal pleural tissue. The MPM cell lines H2452, H2052, and human mesothelioma cell line MSTO-211H showed a significant increase in expression of AM messenger RNA under hypoxic conditions. Our results also show that AM stimulates cell proliferation in vitro through the Raf1 proto-oncogene, serine/threonine kinase (CRAF)/ Mitogen-activated protein kinase kinase 1 (MEK)/Extracellular regulated MAPKinase (ERK) pathway. Furthermore, the proliferation, migration, and invasion of MPM cells were decreased after treatment with anti-AM (αAM) and anti-AM receptor antibodies, thus indicating that MPM cells are regulated by AM. The action of AM was specific and mediated by CLR/RAMP2 and CLR/RAMP3 receptors. In vivo, αAM and AM22-52 antagonist therapies blocked angiogenesis and induced apoptosis in MSTO-211H xenografts, thereby resulting in tumor regression. Histologic examination of tumors treated with AM22-52 and αAM antibody showed evidence of disruption of tumor vasculature with depletion of vascular endothelial cells and a significant decrease in lymphatic endothelial cells., Conclusions: Our findings highlight the importance of the AM pathway in growth of MPM and in neovascularization by supplying and amplifying signals that are essential for pathologic neoangiogenesis and lymphangiogenesis., (Copyright © 2015 International Association for the Study of Lung Cancer.

Management of NSCLC patients is more and more individualized especially on the base of bioguided treatments. In order to guarantee an access for all the patients too this type of strategy, the French NCI supports since 2006 a nationwide network of 28 regional genetics center. The financial support is based on public funds. The French NCI recommends today the assessment of seven biomarkers for all stage IV non squamous NSCLC patients. Due to financial and technical reasons, this recommendation must be followed. However, the molecular profiling of lung cancer patients would ideally be extended across all stages and all histological types of the disease in order to improve our knowledge in this field and provides the patient with an opportunity to access a bioguided treatment as frequently as possible.

Background: Malignant pleural effusion (MPE) is encountered at an advanced stage of disease progression and often heralds a poor prognosis. The most reliable predictive factor of survival in such patients is the primary tumor. Thoracoscopy is often performed for accurate diagnosis and/or thoracoscopic talc insufflation as a therapeutic modality. It remains unknown whether pleural tumor burden, as visualized on thoracoscopy, has potential prognostic value. The objective of this study was to determine the prognostic accuracy of pleural tumor extent and localization (parietal, visceral, or diaphragmatic involvement), as assessed during medical thoracoscopy., Methods: Medical records of all patients who underwent thoracoscopy for suspicion of MPE between 2001 and 2008 at a tertiary care referral hospital were reviewed. Patients were included if pleural metastatic invasion was confirmed on tissue biopsy and survival status ascertained., Results: Four hundred twenty-one patients underwent diagnostic or therapeutic medical thoracoscopy at our referral center. Among them, 122 had confirmed metastatic pleural spread, but survival data were lacking in 15. Primary tumor consisted of non-mall cell lung cancer in 56, breast cancer in 23, melanoma in eight, and other malignancies in 20. Median survival of the entire population was 9.4 months. On univariate analysis, the following variables were significantly associated with reduced median overall survival: pleural metastatic melanoma, age less than 60 years, bloody MPE, extensive pleural adhesions, and widespread visceral pleural nodules (p < 0.05). On multivariate analysis, only melanoma as a primary tumor, pleural fluid appearance and extent of pleural adhesions remained independent and significant predictors of survival., Conclusion: No significant association was found between the extent or localization of pleural tumor burden and overall survival.

Background: Pemetrexed is a key drug for the treatment of malignant pleural mesothelioma. The intrapleural administration of pemetrexed might increase its efficacy and decrease its toxicity in comparison with intravenous administration. The aim of this study was to assess in an animal model the pharmacokinetics of pemetrexed administered intrapleurally compared with intravenously., Methods: Thirty Wistar rats were randomly assigned to four groups defined by route (intravenous or intrapleural) and dose (10 or 100 mg/kg) of pemetrexed. After pemetrexed administration, serial plasma pemetrexed concentrations were analyzed by high performance liquid chromatography to determine the maximum plasma concentration (C(max)), the area under the plasma concentration-time curve (AUC), and the total body clearance (CL)., Results: The C(max) was significantly lower after intrapleural versus intravenous administration of 10 mg/kg pemetrexed (14.36 microg/ml versus 29.83 microg/ml; p = 0.008) or 100 mg/kg pemetrexed (70.64 microg/ml versus 218.64 microg/ml; p = 0.001). At either dose, the AUC and the CL did not significantly differ according to the route of administration., Conclusions: While intravenous and intrapleural administration of pemetrexed yielded similar AUC and CL, the intrapleural route yielded a significantly lower C(max). As Cmax is a determinant of pemetrexed toxicity, intrapleural administration might offer a means of widening the effective therapeutic index of the drug by improving tolerability. Future studies are needed to confirm this hypothesis in malignant pleural mesothelioma patients.

Background: Pulmonary function tests are used to select patients with non-small-cell lung cancer (NSCLC) suitable for thoracic surgery. We studied the impact of pulmonary function tests on both quantitative (morbidity, mortality, and overall survival [OS]) and qualitative (quality of life [QOL]) outcomes of patients undergoing thoracic surgery for NSCLC., Patients and Methods: Patients with proven or highly probable NSCLC referred for thoracic surgery were eligible. The postoperative outcomes morbidity, 90-day mortality, OS, and QOL based on PGWBI and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 were studied according to the results of the preoperative pulmonary function tests (forced expiratory volume in 1 second [FEV(1)]; vital capacity, residual volume, total lung capacity, airways resistance, diffusing capacity corrected for alveolar volume)., Results: A total of 110 patients were studied, with 94 patients eligible for analysis. Postoperative mortality and morbidity affected 9.5% and 40% of patients, respectively. These patients presented with significantly lower preoperative values of vital capacity, total lung capacity, and diffusing capacity corrected for alveolar volume and higher preoperative values of airways resistance compared with patients with an uncomplicated postoperative course. Better survival was correlated with higher preoperative values of FEV(1), vital capacity, total lung capacity, and a lower pulmonary distension, especially when expressed as a percentage of predicted value. None of the postoperative QOL scores was influenced by preoperative pulmonary function tests results., Conclusion: Pulmonary function tests allow a relatively good prediction of postoperative quantitative outcomes such as postoperative morbidity and mortality as well as OS after thoracic surgery for NSCLC. However, pulmonary function tests remain poorly correlated to postoperative qualitative outcomes, making QOL a separate and essential assessment of the health status of patients with resected NSCLC.

Objective: To assess the value of Cyfra 21-1, carcino-embryonic antigen (CEA) and neuron-specific enolase (NSE) combined, all three together as prognostic factors in advanced stage non-small cell lung cancer (NSCLC) patients., Patients and Methods: Serum samples from untreated NSCLC patients were prospectively collected. All assays were performed using commercial kits blind to clinical information. Serum levels of CEA, NSE and Cyfra 21-1 higher than 10, 13 and 3.5 ng/ml, respectively, were considered as elevated., Results: 264 patients (men, 87%), with Performans Status (PS) of 0/1 in 80% and stage IV disease in 65% were studied. Cyfra 21-1, CEA and NSE were elevated in 52.5%, 41.8% and 33.2% of patients, respectively. Median survival was 9 months (range, 1-77). Cyfra 21-1, age, PS, stage as well as the combination of the three markers together correlated with prognosis in univariate analysis. Multivariate analysis demonstrated that age > or = 65 years (HR = 1.3 [1.02-1.70], p = 0.03), PS 2 (HR = 4.3 [3.13-6.11], p < 0.0001), Cyfra 21-1 > or = 3.5 ng/ml (HR = 1.3 [1.06-1.78], p = 0.01) and the combination of the three markers (HR = 1.06 [1.009-1.13], p = 0.02) remained prognostic determinants., Conclusion: Combining Cyfra 21-1, NSE and CEA correlated with prognosis in a significant and independent manner.
