Molecular Alterations in Malignant Pleural Mesothelioma: A Hope for Effective Treatment by Targeting YAP.

Malignant pleural mesothelioma is a rare and aggressive neoplasm, which has primarily been attributed to the exposure to asbestos fibers (83% of cases); yet, despite a ban of using asbestos in many countries, the incidence of malignant pleural mesothelioma failed to decline worldwide. While little progress has been made in malignant pleural mesothelioma diagnosis, bevacizumab at first, then followed by double immunotherapy (nivolumab plus ipilumumab), were all shown to improve survival in large phase III randomized trials. The morphological analysis of the histological subtyping remains the primary indicator for therapeutic decision making at an advanced disease stage, while a platinum-based chemotherapy regimen combined with pemetrexed, either with or without bevacizumab, is still the main treatment option.

Phase II study of afatinib plus pembrolizumab in patients with squamous cell carcinoma of the lung following progression during or after first-line chemotherapy (LUX-Lung-IO).

Introduction: Afatinib and pembrolizumab have separately shown survival benefit in patients with squamous cell carcinoma (SqCC) of the lung, and there is biological rationale for concurrent inhibition of the programmed death ligand-1 and epidermal growth factor receptor (EGFR) pathways in this patient population.

Materials And Methods: This open-label, single-arm study enrolled patients with SqCC of the lung who had progressed during/after first-line chemotherapy and comprised two parts: a safety run-in to establish the recommended phase II dose (RP2D; afatinib 40 mg or 30 mg once daily with pembrolizumab 200 mg every 3 weeks); and the main part assessing efficacy and safety of the RP2D. The primary endpoint was objective response rate (ORR); secondary endpoints included the RP2D, progression-free survival (PFS) and overall survival (OS).

Combination of Trastuzumab, Pertuzumab, and Docetaxel in Patients With Advanced Non-Small-Cell Lung Cancer Harboring Mutations: Results From the IFCT-1703 R2D2 Trial.

Purpose: exon 20 insertions and point mutations are oncogenic drivers found in 1%-2% of patients with non-small-cell lung cancer (NSCLC). No targeted therapy is approved for this subset of patients. We prospectively evaluated the effectiveness of the combination of two antibodies against human epidermal growth factor 2 (HER2 [HER2] trastuzumab and pertuzumab with docetaxel; trastuzumab and pertuzumab) and docetaxel.

Postoperative radiotherapy versus no postoperative radiotherapy in patients with completely resected non-small-cell lung cancer and proven mediastinal N2 involvement (Lung ART): an open-label, randomised, phase 3 trial.

Background: In patients with non-small-cell lung cancer (NSCLC), the use of postoperative radiotherapy (PORT) has been controversial since 1998, because of one meta-analysis showing a deleterious effect on survival in patients with pN0 and pN1, but with an unclear effect in patients with pN2 NSCLC. Because many changes have occurred in the management of patients with NSCLC, the role of three-dimensional (3D) conformal PORT warrants further investigation in patients with stage IIIAN2 NSCLC. The aim of this study was to establish whether PORT should be part of their standard treatment.

[D-CBP study: Evaluation of lung cancer management times].

Introduction: Lung cancer is the leading cause of cancer-related death. Delays may have an impact on patient survival. The objective of this study was to evaluate the diagnostic and therapeutic management times for patients admitted for lung cancer treatment in the Respiratory Department of CHU de Caen Normandie.

Consolidation nivolumab and ipilimumab versus observation in limited-disease small-cell lung cancer after chemo-radiotherapy - results from the randomised phase II ETOP/IFCT 4-12 STIMULI trial.

Background: Concurrent chemotherapy and thoracic radiotherapy followed by prophylactic cranial irradiation (PCI) is the standard treatment in limited-disease small-cell lung cancer (LD-SCLC), with 5-year overall survival (OS) of only 25% to 33%.

Patients And Methods: STIMULI is a 1:1 randomised phase II trial aiming to demonstrate superiority of consolidation combination immunotherapy versus observation after chemo-radiotherapy plus PCI (protocol amendment-1). Consolidation immunotherapy consisted of four cycles of nivolumab [1 mg/kg, every three weeks (Q3W)] plus ipilimumab (3 mg/kg, Q3W), followed by nivolumab monotherapy (240 mg, Q2W) for up to 12 months.

[Lung involvement of pyoderma gangrenosum: Diagnostic and therapeutic discussion based on a case report and a targeted literature review].

Introduction: Pyoderma gangrenosum (PG) is a rare, mainly dermatological condition, whose unusual and little-known lung involvement presents a diagnostic and therapeutic challenge.

Case Report: A 66-year-old man, followed for 6 years for an IgA monoclonal gammopathy of undetermined significance and an initially cutaneous corticosteroid-dependent PG, received a pneumonectomy for a mass suspected of neoplasia, that turns out to be a PG pulmonary localisation. During successive pneumopathies, sometimes dyspneic and excavated, several hypotheses are discussed.

Circulating Tumor DNA as a Prognostic Determinant in Small Cell Lung Cancer Patients Receiving Atezolizumab.

Background: The IFCT-1603 trial evaluated atezolizumab in small cell lung cancer (SCLC). The purpose of the present study was to determine whether circulating tumor DNA (ctDNA), prospectively collected at treatment initiation, was associated with the prognosis of SCLC, and whether it identified patients who benefited from atezolizumab.

Methods: 68 patients were included in this study: 46 patients were treated with atezolizumab and 22 with conventional chemotherapy.

Switch maintenance chemotherapy versus observation after carboplatin and weekly paclitaxel doublet chemotherapy in elderly patients with advanced non-small cell lung cancer: IFCT-1201 MODEL trial.

Purpose: Maintenance chemotherapy is a reasonable choice for patients with metastatic non-small cell lung carcinoma (NSCLC) not progressing after induction therapy with a platinum-based doublet. Nevertheless, there have been no studies dedicated to elderly patients.

Patients And Methods: We conducted a randomised trial in patients aged 70-89 years, with advanced NSCLC (with neither EGFR mutation nor ALK rearrangement), who had not progressed after four cycles of monthly carboplatin and weekly paclitaxel in order to compare maintenance with either pemetrexed (500 mg/m d1, 22) in patients with non-squamous cell carcinoma or gemcitabine (1,150 mg/m d1, 8, 22) in squamous cell carcinoma to simple observation.

Late cardiac adverse events in patients with cancer treated with immune checkpoint inhibitors.

Background: Immune checkpoint inhibitor (ICI)-associated early cardiac adverse events (CAEs), mostly acute and fulminant myocarditis, have been well characterized and mainly occur during the first 90 days after ICI therapy initiation. ICI-associated late CAEs (occurring after the first 90 days of treatment) have not yet been described.

Methods: First, we compared characteristics of a cohort involving early (defined as a CAE time to onset (TTO) of <90 days after ICI therapy initiation) and late (defined as a CAE TTO of ≥90 days after ICI therapy initiation) ICI-associated CAE consecutive cases who were referred to three French cardio-oncology units.

Real-Life Efficacy of Osimertinib in Pretreated Octogenarian Patients with T790M-Mutated Advanced Non-small Cell Lung Cancer.

Background: The resistance mutation T790M is reported in 50-60% of patients pretreated with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs). Osimertinib has been approved in these patients, but data in octogenarians remain rare.

Objective: The objective of this retrospective analysis was to evaluate in real life the efficacy of osimertinib in a population of octogenarian patients.

Afatinib With Pembrolizumab for Treatment of Patients With Locally Advanced/Metastatic Squamous Cell Carcinoma of the Lung: The LUX-Lung IO/KEYNOTE 497 Study Protocol.

Background: Afatinib is a selective, irreversible ErbB family blocker that has shown survival benefit in lung squamous-cell carcinoma (SCC) patients. Pembrolizumab, a humanized immunoglobulin G4 monoclonal antibody to the programmed cell death 1 (PD-1) receptor, has also shown survival benefit in lung SCC. Concurrent inhibition of the PD-1 and epidermal growth factor receptor (EGFR) pathways represents a rational approach to improve responses and delay the onset of treatment resistance in lung SCC.

A Randomized Non-Comparative Phase II Study of Anti-Programmed Cell Death-Ligand 1 Atezolizumab or Chemotherapy as Second-Line Therapy in Patients With Small Cell Lung Cancer: Results From the IFCT-1603 Trial.

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.

Nivolumab Causing a Polymyalgia Rheumatica in a Patient With a Squamous Non-Small Cell Lung Cancer.

The anti-programmed cell-death-1 antibody, nivolumab, has been recently approved for the treatment of advanced non-small cell lung cancer. Although, today, immune-related adverse effects such as dermatologic, digestive, hepatic, and endocrine toxicities are well-known with immune checkpoint inhibitors, rheumatic diseases are less well described. Herein, we report the case of a patient without a history of arthritis who developed polymyalgia rheumatica after 13 cycles of nivolumab used for the treatment of advanced non-small cell lung cancer.

Generating harmonized SUV within the EANM EARL accreditation program: software approach versus EARL-compliant reconstruction.

Background: Evolutions in hardware and software PET technology, such as point spread function (PSF) reconstruction, have been shown to improve diagnostic performance, but can also lead to important device-dependent and reconstruction-dependent variations in standardized uptake values (SUVs). This may preclude the multicentre use of SUVs as a prognostic or diagnostic tool or as a biomarker of the early response to antineoplastic treatments. This study compared two SUV harmonization strategies using a newer reconstruction algorithm that improves lesion detection while maintaining comparability with older systems: (1) the use of a second reconstruction compliant with harmonization standards and (2) the use of a proprietary software tool (EQ.

F-FDG PET/CT heterogeneity quantification through textural features in the era of harmonisation programs: a focus on lung cancer.

Purpose: Quantification of tumour heterogeneity in PET images has recently gained interest, but has been shown to be dependent on image reconstruction. This study aimed to evaluate the impact of the EANM/EARL accreditation program on selected F-FDG heterogeneity metrics.

Methods: To carry out our study, we prospectively analysed 71 tumours in 60 biopsy-proven lung cancer patient acquisitions reconstructed with unfiltered point spread function (PSF) positron emission tomography (PET) images (optimised for diagnostic purposes), PSF-reconstructed images with a 7-mm Gaussian filter (PSF) chosen to meet European Association of Nuclear Medicine (EANM) 1.

Cost-effectiveness of three strategies for second-line erlotinib initiation in nonsmall-cell lung cancer: the ERMETIC study part 3.

Several clinical and biological parameters are known to influence the efficacy of second-line erlotinib therapy for nonsmall cell lung cancer (NSCLC), but their medico-economic impact has not been evaluated. The objective of this study was to compare the incremental cost-effectiveness ratios of strategies for second-line erlotinib initiation in NSCLC: clinically guided initiation (nonsmoking females with adenocarcinoma received erlotinib; all other patients received docetaxel) and biologically guided selection (patients with epidermal growth factor receptor (EGFR) mutation received erlotinib; patients with wild-type EGFR or unknown status received docetaxel), compared with initiation with no patient selection (strategy reference). A Markov model was constructed.

[Epidemiology, molecular biology, diagnostic and therapeutic strategy of malignant pleural mesothelioma in 2007 - an update].

Malignant pleural mesothelioma (MPM) is a rare tumour due to occupational asbestos exposure. The incidence of MPM will continue to increase until 2020-2030. The incidence reaches 100 cases/million/year in occupationally exposed populations as opposed to 1 case/million/year in the general population, leading to 800 to 1,000 cases per year in France.

[Primitive metastasizing bronchial carcinoid with long survival].

Background: Metastatic bronchial carcinoid tumours are rare but some patients have a prolonged survival. A new functional imagery now makes it possible to supplement the assessment of the extent of disease.

Observation: A 57 year old patient was referred for dyspnoea on exertion revealing an upper left lobar tumour, with carcinoid syndrome.

[The place of targeted therapies in the management of non-small cell bronchial carcinoma. Biological mechanisms of bronchial carcinogenesis: towards a better understanding and the development of new therapies].

An increasing knowledge of cell signal transduction pathways has led to a better understanding of multi-step bronchial carcinogenesis. This new data has been used to design new drugs targeting specific proteins involved in epithelial cell transformation. New biotherapies are a major part of the evolving strategies to fight lung cancer and actually represent a true revolution for subsets of patients.

[Hydration of patients treated with cisplatin: practical investigation and establishment of a protocol].

Background: Administration of cisplatin requires hyperhydration of the patient to prevent nephrotoxic effects of this molecule.

Materials And Methods: A survey done in different hospitals - university hospitals, general hospitals and cancer institutes--has shown a large variability in the hydration protocols. A multidisciplinary group was set up in our university hospital comprising oncologists, nephrologists and pharmacists.
