COMPOSIT study: evaluating osimertinib combination with targeted therapies in EGFR-mutated non-small cell lung cancer.

Introduction: The emergence of diverse resistance mechanisms after osimertinib therapy, including on-target epidermal growth factor receptor (EGFR) mutations and off-target alterations, warrants investigation of novel therapeutics to overcome these challenges and improve patient outcomes.

Methods: COMPOSIT was a French, retrospective, multicenter, cohort study of the effectiveness and tolerability of osimertinib in combination with other targeted therapies in patients with advanced EGFR-mutant (EGFRm) non-small cell lung cancer (NSCLC) who harbored other oncogenic drivers as primary or acquired resistance mechanisms. Real-world progression-free survival (rwPFS), overall survival (OS), and objective response rate (ORR) were the primary endpoints.

The CheckMate 816 trial: a milestone in neoadjuvant chemoimmunotherapy of nonsmall cell lung cancer.

Advancements in immunotherapy in the perioperative setting have revolutionised the treatment of resectable nonsmall cell lung cancer (NSCLC). Here we present the methodology and results of the clinical trial CheckMate 816 demonstrating the benefit of neoadjuvant therapy with nivolumab plus chemotherapy compared with chemotherapy alone. Furthermore, this article discusses the implications for future practice in resectable NSCLC and the need for future research.

Why does circadian timing of administration matter for immune checkpoint inhibitors' efficacy?

Background: Tolerability and antitumour efficacy of chemotherapy and radiation therapy can vary largely according to their time of administration along the 24-h time scale, due to the moderation of their molecular and cellular mechanisms by circadian rhythms. Recent clinical data have highlighted a striking role of dosing time for cancer immunotherapy, thus calling for a critical evaluation.

Methods: Here, we review the clinical data and we analyse the mechanisms through which circadian rhythms can influence outcomes on ICI therapies.

Successive next-generation sequencing strategy for optimal fusion gene detection in non-small-cell lung cancer in clinical practice.

Metastatic non-small-cell lung cancer (NSCLC) displays various molecular alterations in the RAS-MAPK pathway. In particular, NSCLCs show high rates of targetable gene fusion in ALK, RET, ROS1, NRG1 and NTRK, or MET exon 14 skipping. Rapid and accurate detection of gene fusion in EGFR/KRAS/BRAF mutations is important for treatment selection especially for first-line indications.

Effect of immunotherapy-infusion time of day on survival of patients with advanced cancers: a study-level meta-analysis.

Background: Immune checkpoint inhibitors (ICIs) have become the standard of care for numerous malignancies. Emerging evidence suggests that the time of day (ToD) of ICI administration could impact the outcomes of patients with cancer. The consistency of ToD effects on ICI efficacy awaits initial evaluation.

Association Between Lung Immune Prognostic Index and Durvalumab Consolidation Outcomes in Patients With Locally Advanced Non-Small-Cell Lung Cancer.

Introduction: The LIPI, based on pretreatment derived neutrophils/[leukocytes-neutrophils] ratio (dNLR) and LDH, is associated with immune checkpoint inhibitors (ICI) outcomes in advanced non-small-cell lung cancer (NSCLC). We aimed to assess baseline LIPI correlation with durvalumab consolidation outcomes in the locally advanced setting.

Material And Methods: Multicentre retrospective study (330 patients) with stage III unresectable NSCLC treated with durvalumab after chemo-radiotherapy between April 2015 and December 2020; 65 patients treated with chemo-radiotherapy only.

Holistic management of patients with progressive pulmonary fibrosis.

Unlabelled: Progressive pulmonary fibrosis (PF) is a complex interstitial lung disease that impacts substantially on patients' daily lives, requiring personalised and integrated care. We summarise the main needs of patients with PF and their caregivers, and suggest a supportive care approach. Individualised care, education, emotional and psychological support, specialised treatments, and better access to information and resources are necessary.

Radiation-induced lung injury after breast cancer treatment: incidence in the CANTO-RT cohort and associated clinical and dosimetric risk factors.

Purpose: Radiation-induced lung injury (RILI) is strongly associated with various clinical conditions and dosimetric parameters. Former studies have led to reducing radiotherapy (RT) doses to the lung and have favored the discontinuation of tamoxifen during RT. However, the monocentric design and variability of dosimetric parameters chosen have limited further improvement.

[Diagnosis and management of interstitial lung disease induced by antibody-drug conjugates in breast cancer: A French expert opinion paper].

Interstitial lung disease (ILD) has been reported with many cancer drugs including some recent antibody-drug conjugates (ADCs). The mechanisms of ILD induced by many chemotherapy drugs, other drug classes and ADCs used in cancer, including breast cancer, are not clearly elucidated. In the absence of specific clinical or radiological signs, the diagnosis of drug-induced ILD is often a diagnosis of exclusion.

PDL1-status predicts primary resistance of metastatic, EGFR-mutated non small cell lung cancers to EGFR tyrosine-kinase inhibitors.

Background: EGFR tyrosine-kinase inhibitors (TKIs) are the reference treatment for metastatic, EGFR-mutated, non-small-cell lung cancers (EGFRm NSCLCs). However, 16-20% of those tumors progress early (3-6 months) and factors predicting that resistance are unknown. This study was undertaken to examine PDL1 status as such a factor.

Total Metabolic Tumor Volume on 18F-FDG PET/CT Is a Useful Prognostic Biomarker for Patients with Extensive Small-Cell Lung Cancer Undergoing First-Line Chemo-Immunotherapy.

: We aimed to evaluate the prognostic value of imaging biomarkers on 18F-FDG PET/CT in extensive-stage small-cell lung cancer (ES-SCLC) patients undergoing first-line chemo-immunotherapy. In this multicenter and retrospective study, we considered two cohorts, depending on the type of first-line therapy: chemo-immunotherapy (CIT) versus chemotherapy alone (CT). All patients underwent baseline 18-FDG PET/CT before therapy between June 2016 and September 2021.

ICU admission for solid cancer patients treated with immune checkpoint inhibitors.

Background: Immune checkpoint inhibitors (ICI) have revolutionized the management of cancer. They can induce immune-related adverse events (irAE) leading to intensive care unit (ICU) admission. We aimed to describe irAEs for ICU admissions in solid cancer patients treated with ICIs.

Incidence, management, and outcome of lung cancer in patients with long-term oxygen therapy.

Background: Here, we aimed to assess the specific features of lung cancer in patients with long-term oxygen therapy (LTOT), and compare their outcomes with patients suffering from lung cancer without LTOT.

Methods: This retrospective, case-controlled study included patients with LTOT and an incident diagnosis of lung cancer treated at Rouen University Hospital.

Results: Out of 2201 patients with LTOT, 31 were diagnosed with lung cancer.

[Postoperative radiotherapy in non-small cell lung cancer stage IIIA - N2: Focus and perspectives].

Patients with resectable stage IIIA - N2 lung cancer represent a very heterogeneous population with variable risks of postoperative recurrence depending on the type of N2 involvement (unisite N2, multisite N2, bulky N2, extra-capsular rupture, incomplete resection…). This heterogeneity associated with the difficulty of carrying out prospective randomized studies with sufficient power in stages IIIA - 2, results in the absence of clear and consensual recommendations (except for stages IIIA - N2 resectable R0, since LungART and PORT-C studies). The objective of this article is to make an update on the place of postoperative radiotherapy in the management of stages IIIA - N2 following the publication of two recent randomized trials (PORT-C and LungART) but also compare them fort a better understanding of the current issues raised by these first published results.

Histomolecular Resistance Mechanisms to First-Line Osimertinib in EGFR-Mutated Advanced Non-Small Cell Lung Cancer: A Multicentric Retrospective French Study.

Background: Osimertinib is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) used in first line for the treatment of advanced EGFR-mutated non-small cell lung cancer (NSCLC).

Objective: The identification of related histomolecular resistance mechanisms to first-line osimertinib is a critical step to define the optimal treatment strategy beyond progression.

Patients And Methods: All consecutive patients treated in the first line with osimertinib for advanced EGFR-mutated NSCLC at 10 hospitals in the Greater Paris area between April 2015 and January 2021 were included.

Successful sequential tyrosine kinase inhibitors to overcome a rare compound of EGFR exon 18-18 and EGFR amplification: A case report.

Background: New mutational detection techniques like next-generation sequencing have resulted in an increased number of cases with uncommon mutation and compound mutations [3%-14% of all epidermal growth factor receptor (EGFR) mutations]. In rare exon 18 mutations (3%-6%), G719X and E709X represent the majority, but CMut associating these exon 18 points mutations are even rarer, making the understanding of the impact of epidermal growth factor receptor tyrosine kinase inhibitors still limited. Three generations of EGFR tyrosine kinase inhibitors (TKIs) are available to target EGFR mutations, but according to the types of mutations, the sensitivity to TKI is different.

Durvalumab consolidation in patients with unresectable stage III non-small cell lung cancer with driver genomic alterations.

Introduction: Durvalumab is the standard-of-care as consolidation therapy after chemo-radiotherapy in stage III unresectable non-small cell lung cancer (NSCLC); however, its activity across patients with NSCLC harbouring driver genomic alterations (dGA) is poorly characterised.

Material And Methods: Multicentre retrospective study including patients with stage III unresectable NSCLC treated with durvalumab after chemo-radiotherapy between April 2015 and October 2020 at 26 centres in Europe and America. Clinical and biological data were collected; dGA included: EGFR/BRAF/KRAS mutations (m) and ALK/ROS1 rearrangements (r).
