Background: The established role of morphological evaluation of tumour-infiltrating lymphocytes (TILs) with immune checkpoint inhibitors (ICIs) in non-small cell lung cancer (NSCLC) is unknown. We aimed to determine TIL association with the outcome for ICIs and for chemotherapy in advanced NSCLC., Methods: This is a multicenter retrospective study of a nivolumab cohort of 221 patients treated between November 2012 and February 2017 and a chemotherapy cohort of 189 patients treated between June 2009 and October 2016. Patients with available tissue for stromal TIL evaluation were analysed. The presence of a high TIL count (high-TIL) was defined as ≥10% density. The primary end-point was overall survival (OS)., Results: Among the nivolumab cohort, 64% were male, with median age of 63 years, 82.3% were smokers, 77% had performance status ≤1 and 63% had adenocarcinoma histology. High-TIL was observed in 22% patients and associated with OS (hazard ratio [HR] 0.48; 95% confidence interval [95% CI]: 0.28-0.81) and progression-free survival [PFS] (HR = 0.40; 95% CI: 0.25-0.64). Median PFS was 13.0 months (95% CI: 5.0-not reached) with high-TIL versus 2.2 months (95% CI: 1.7-3.0) with the presence of a low TIL count (low-TIL). Median OS for high-TIL was not reached (95% CI: 12.2-not reached) versus 8.4 months (95% CI: 5.0-11.6) in the low-TIL group. High-TIL was associated with the overall response rate (ORR) and disease control rate (DCR) (both, P < .0001). Among the chemotherapy cohort, 69% were male, 89% were smokers, 86% had performance status ≤1 and 90% had adenocarcinoma histology. High-TIL was seen in 37%. Median PFS and OS were 5.7 months (95% CI: 4.9-6.7) and 11.7 months (95% CI: 9.3-13.0), respectively, with no association with TILs., Conclusions: High-TIL was associated with favourable outcomes in a real-world immunotherapy cohort of patients with NSCLC, but not with chemotherapy, suggesting that TILs may be useful in selecting patients for immunotherapy., Competing Interests: Conflicts of interest statement The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Laura Mezquita reports receiving research sponsorship from Bristol-Myers Squibb and Boehringer Ingelheim; consulting and advisory roles in Roche Diagnostics and Takeda; lectures and educational activities in Bristol-Myers Squibb, Tecnofarma and Roche; receiving travel, accommodations and expenses from Roche; and participation in the mentorship program with key opinion leaders, funded by AstraZeneca.

Purpose: Anti Programmed Death-ligand (PD1/PD-L1) directed immune-checkpoint-inhibitors (ICI) are widely used to treat patients with advanced non-small cell lung cancer (NSCLC) who progress after first line chemotherapy. The best strategy after early progression under first line has not been specifically studied., Patients and Methods: We conducted a multicenter, retrospective study including all consecutive NSCLC patients progressing within the first 3 months following introduction of first-line chemotherapy and being treated with second line ICI monotherapy or chemotherapy between March 2010 and November 2017. We analysed the clinicopathological data and outcome under second line chemotherapy vs. second line ICI: objective response rate (ORR), progression-free survival (PFS), overall survival (OS., Results: We identified 176 patients with refractory disease, 99 who received subsequent immunotherapy and 77 undergoing chemotherapy. The 2 populations were comparable regarding the main prognostic criteria, median age was 60, main histology was adenocarcimoma (68.2%). PFS was not significantly different between both treatments 1.9 [1.8-2.1] versus 1.6 month [1.4-2.0] (P=0.125). Compared to chemotherapy, ICI treated patients had a superior OS (P=0.03) (Median [95% CI] OS 4.6 [2.8-6.7] versus 4.2 months [3.4-5.9] and a non-significant improvement in ORR (17.2% versus 7.9%, respectively, P=0.072). Poor performance status (ECOG PS≥2) and a higher number of metastatic sites (≥3) were associated with poorer prognosis. KRAS-mutated patients did not seem to benefit more from ICI than chemotherapy., Conclusions: ICI appears to be the preferred second-line treatment for patients who are refractory to first line chemotherapy., (Copyright © 2020.

Background: Aging is an important risk factor for cancers and is associated with poor prognosis. Weakness of the immune system, also called immunosenescence may occur with older age. The impact of aging on efficacy and safety of immune checkpoint blockers, such as anti-programmed death (ligand) PD-(L)1, remains undetermined. This study aims to evaluate the incidence of immune-related adverse events (irAEs) in patients aged 70 years or older than their younger counterparts., Methods: Patients with advanced solid tumors treated at Gustave Roussy with an anti-PD-(L)1 monotherapy between June 2014 and October 2017 were prospectively included within the dedicated irAEs pharmacovigilance registry REISAMIC (Registre des Effets Indésirables Sévères des Anticorps Monoclonaux Immunomodulateurs en Cancérologie). The incidence of irAEs of grade ≥II was compared between patients aged ≥70 (old patients, OP) versus patients aged < 70 years (young patients, YP) using a chi-squared test. Survivals were estimated using the Kaplan-Meier method., Results: Among the 603 patients treated by anti-PD(L)1, 191 were ≥70 y.o (OP) and 424 < 70 y.o (YP). The median (range) age of OP and YP were respectively 77 (70-93) and 59 years old (17-69). A total of 165 irAEs occurred in these patients (103 grade II and 58 grade III-IV). The overall incidence of grade ≥II irAEs was higher in OP than in YP (33% versus 25%, p = 0.03). In addition, OP were more prone of having multiples irAEs compared with YP (p = 0.037). Skin toxicities were more frequent in OP than in YP (p = 0.007) but endocrine toxicities were less frequent in OP than in YP (p = 0.044). This higher level of irAEs seems to be responsible for a higher rate of treatment discontinuation in OP (p = 0.2). There was no statistical difference in median time to toxicity, exposure to steroids or survival between the two groups., Conclusion: Although anti-PD-(L)1 immunotherapies remain an acceptable treatment option for older patients, prescribers should be aware that irAEs are more frequent in the elderly. Further translational studies are warranted to better understand the relationship between aging and irAEs., (Copyright © 2020. Published by Elsevier Ltd.)

Background: Nivolumab and pembrolizumab were initially developed using weight-based regimen doses. Recently, fixed-dose regimens were commercialised with reference weights higher than the accurate weight of patients with cancer in routine practice. This may have important economic consequences for healthcare systems., Material and Methods: Budget impact analysis was performed using real-world data both from Gustave Roussy database and the French National Hospital Discharge database and including patients treated with either nivolumab or pembrolizumab at Gustave Roussy and in France before the approval of fixed-dosing regimens in Europe. Main outcome is the expected annual budget impact of fixed-dosing regimens in France., Results: From January to April 2018, 978 perfusions of anti-programmed cell death protein 1 were administered at our institution including 560 perfusions of nivolumab in 103 patients and 418 perfusions of pembrolizumab in 125 patients mainly treated for lung cancer and melanoma. The mean extra cost attributable to flat doses would have amounted to €284 (95% confidence interval [CI]: 241-327) per infusion of nivolumab and to €1287 (95% CI: 1200-1373) per infusion of pembrolizumab. Annually, at Gustave Roussy, it would represent an extra cost of € 477 120 (95% CI: 404 880-549 360) and €1 613 898 (95% CI: 1 504 800-1 721 742), respectively, for the year 2018. At the French national level, the expected annual budget impact is estimated at €55 162 211 for the year 2017., Conclusions: Weight references for fixed-dose regimens do not reflect the accurate mean weight of patients under cancer treatment and are likely to have substantial economic impact for healthcare systems., (Copyright © 2019 Elsevier Ltd.

The anti-tumour and anti-metastatic properties of heparins have not been tested in patients with early stage cancer. Whether adjuvant low molecular weight heparin (LMWH) tinzaparin impacts the survival of patients with resected non-small cell lung cancer (NSCLC) was investigated.Patients with completely resected stage I, II or IIIA NSCLC were randomly allocated to receive subcutaneous tinzaparin 100 IU·kg -1 once a day for 12 weeks or no treatment in addition to standard of care. The trial was open-label with blinded central adjudication of study outcomes. The primary outcome was overall survival.In 549 patients randomised to tinzaparin (n=269) or control (n=280), mean±sd age was 61.6±8.9 years, 190 (34.6%) patients had stage II-III disease, and 220 (40.1%) patients received adjuvant chemotherapy. Median follow-up was 5.7 years. There was no significant difference in overall survival between groups (hazard ratio (HR) 1.24, 95% CI 0.92-1.68; p=0.17). There was no difference in the cumulative incidence of recurrence between groups (subdistribution HR 0.94, 95% CI 0.68-1.30; p=0.70).Adjuvant tinzaparin had no detectable impact on overall and recurrence-free survival of patients with completely resected stage I-IIIA NSCLC. These results do not support further clinical evaluation of LMWHs as anti-tumour agents., Competing Interests: Conflict of interest: G. Meyer reports grants and non-financial support from Leo Pharma, outside the submitted work.

Background: This phase I study evaluated the safety and efficacy of the oral mTOR inhibitor everolimus in combination with thoracic radiotherapy followed by consolidation chemotherapy in locally advanced or oligometastatic untreated non-small-cell lung cancer (NSCLC)., Patients and Methods: Everolimus dose was escalated in incremental steps [sequential cohorts of three patients until the occurrence of dose-limiting toxicity (DLT)] and administered orally weekly (weekly group: dose of 10, 20 or 50 mg) or daily (daily group: 2.5, 5 or 10 mg), 1 week before, and during radiotherapy until 3.5 weeks after the end of radiotherapy. Two cycles of chemotherapy (cisplatin-navelbine) were administrated 4.5 weeks after the end of radiotherapy., Results: Twenty-six patients were included in two centers, 56% had adenocarcinoma and 84% had stage III disease. In the weekly group (12 assessable patients), everolimus could be administered safely up to the maximum planned weekly dose of 50 mg; however, one patient experienced a DLT of interstitial pneumonitis at the weekly dose level of 20 mg. In the daily group (9 assessable patients): one DLT of interstitial pneumonitis with a fatal outcome was observed at the daily dose level of 2.5 mg; two other DLTs (one grade 3 esophagitis and one bilateral interstitial pneumonitis) were found at the daily dose level of 5 mg. Overall there were five patients with G3-4 interstitial pneumonitis related to treatment. Among 22 assessable patients for response, there were 9 (41%) partial response and 7 (32%) stable disease. At a median follow-up of 29 months, the 2-year overall survival and progression-free survival actuarial rates were 31% and 12%, respectively., Conclusion: In previously untreated and unselected NSCLC patients, the recommended phase II dose of everolimus in combination with thoracic radiotherapy is 50 mg/week. Pulmonary toxicity is of concern and should be carefully monitored to establish the potential role of mTOR inhibitor with concomitant radiotherapy., Eudract N: 2007-001698-27., (© The Author 2015.

Epithelial thymic tumours are rare and sometimes difficult to classify. Since 2010, the French National Cancer Institute supports a French national network, called Rythmic, devoted to the treatment of these tumours through regional and national multidisciplinary conferences using the web. All the tumours are secondarily reviewed by a French pathology national network for classification and staging. This review focuses on the presentation of the Rythmic network, and mainly to the Pathology review process., (Copyright © 2014. Published by Elsevier Masson SAS.)

Background: The role of second-line chemotherapy (SLC) has still not been established in malignant pleural mesothelioma (MPM) but SLC is increasingly used because many patients are still fit at the time of the progression of the disease., Methods: In this retrospective study, the authors reviewed their experience with SLC in pemetrexed-pretreated patients with MPM at two French thoracic oncology units (institut Gustave-Roussy, Villejuif, and hôpital d'Instruction des Armées Percy, Clamart)., Results: Between January 2005 and December 2006, 84 consecutive patients with progressing MPM after pemetrexed chemotherapy were enrolled. Forty-four patients received an SLC. There were 30 men and 14 women. The median age was 58 years (range: 34 to 76 years). Most patients had a performance status (PS) less than or equal to 1 (82%) and an epithelial histological subtype (91 %). The median time to progression (TTP) after first-line chemotherapy was 6.1 months. The SLC was a pemetrexed therapy in 21 patients and a new regime in 20 patients (gemcitabine alone or with oxaliplatin). The other three patients were enrolled in a phase I study. According to the Recist criteria, a partial response was observed in four patients and the disease was stabilised in six patients after SLC. The median TTP after SLC was 3.8 months. The median survival was 12.2 months (range: 2 to 72 months). Four of these 44 patients then received third-line (4.8 %) and two received fourth-line therapy (2.4 %)., Conclusions: This experience indicates the feasibility of administering SLC in patients with MPM who are healthy at the time of the progression of the disease. The optimal treatment has not been defined to date and prospective trials are needed., (Copyright © 2010 Elsevier Masson SAS. All rights reserved.)

Targeted molecular therapies, mainly enzyme inhibitors and humanized antibodies, are being widely developed, especially in the area of lung cancer. Though often considered to be better tolerated than conventional cytotoxic chemotherapies, targeted molecular therapies induce specific toxicities that may have detrimental effects on the quality of life. We sum up various toxicities from targeted treatment available for lung cancer in France with the aim of improving their prevention, diagnosis and management.

A quantitative real-time reverse transcriptase-polymerase chain reaction (RT-PCR) method based on TaqMan technology was developed to determine the presence and amount of enterovirus RNA. In order to prevent false-negative results, a one-step multiplex RT-PCR was optimized. It contains two dual-labelled fluorogenic probes to quantify the 5' noncoding region of enterovirus and detect an internal positive control. In the present study, 104 cerebrospinal fluid samples collected during an outbreak of enteroviral meningitis were analyzed using this method. Amplification of the internal positive control was effective in all but two specimens, confirming the absence of PCR inhibitors and allowing the results of amplification to be validated. The sensitivity of the RT-PCR was 96.8%, while that of cell culture was 34.9%. Genomic viral loads found ranged between 3.3 and 5.9 log(10) copies per milliliter of cerebrospinal fluid (mean, 4.8 log(10) copies/ml). This fluorogenic enterovirus RT-PCR allows large numbers of samples to be screened rapidly. Moreover, its sensitivity and reproducibility make it highly reliable. With these characteristics, the enterovirus RT-PCR can be a useful tool that may offer considerable benefit in the clinical management of patients with enteroviral infections.

Genetic analysis of selected genome regions of hepatitis A Virus (HAV) suggested that distinct genotype could be defined in different geographic locations. In order to study the degree of genetic variability among HAV isolated during a single epidemic outbreak, sequences from a 148 base pair segment within the VP1 amino terminal region were obtained for eight distinct HAV isolates from an outbreak that occurred in North Bretagne (France). These sequences were compared among themselves and with published sequences from 30 different strains that represented different HAV sub-genotypes that were isolated all over the world. Phylogenetic analysis revealed an extensive genetic heterogeneity among strains belonging to the same outbreak and revealed co-circulation of sub-genotype IA, IB, and the presence of IIIA sub-genotype for the first time in a Mediterranean country., (Copyright 2001 Wiley-Liss, Inc.)

The typing fo Human Papillomavirus (HPV) was carried out in cervical lesions in order to decide on the best therapy to carry out in mild and medium dysplasias of the cervix. 131 patients who had an iodo-negative zone or a smear suggesting an HPV infection had microbiopsies carried out under colposcopic control. Every lesion had two biopsies carried out side by side to study the histopathology and the virology. Dysplastic lesions were found in 93 biopsies. A search for the DNA of HPV 6a, 16 and 18 was carried out using a Southern blot technique with 32P following the method of Random multipriming. Hybridization was carried out in strict and non-strict conditions. In 43 cases out of 93 dysplasias a virus was found: 2 HPV 6a, 14 HPV 16, 1 HPV 18 and 26 X HPV's (not typed). The number of HPV's that could be detected increased according to the severity of the dysplasia which was also found in frequency of type 16. Where the biopsies showed no dysplasia type 16 was found in four out of seven viruses. In this study electrophoretic profiles for type 16 were found in four cases suggesting that they were integrated into the chromosome of the cell. The low percentage of HPV found in mild or moderate dysplasias (4 type 16 out of 61 biopsies) shows that at present this test can not be used as an aid in choosing treatment.
