Real-World Outcomes of Pralsetinib in RET Fusion-Positive NSCLC.

Introduction: Pralsetinib is a RET inhibitor found to have antitumor activity in advanced, metastatic, fusion-positive NSCLC.

Objective: To assess real-world efficacy of pralsetinib and treatment sequences in patients with RET fusion-positive NSCLC.

Design: Retrospective study of consecutive patients enrolled in the French expanded-access program for pralsetinib from December 1, 2019, to December 31, 2021.

Tumor-intrinsic chemosensitivity assessed by KELIM and prognosis by status in patients with advanced ovarian carcinomas.

Objective: Treatment of high-grade serous ovarian carcinomas relies on surgery and chemotherapy, potentially followed by bevacizumab and/or poly (ADP-ribose) polymerase inhibitors (PARPi). The modeled CA-125 ELIMination rate constant K (KELIM) is a pragmatic indicator of tumor primary chemosensitivity. Although it is well established that mutations are associated with platinum sensitivity, the relationship between status and KELIM score has yet to be elucidated.

Real-World Survival Impact of New Treatment Strategies for Lung Cancer: A 2000-2020 French Cohort.

Over the past 20 years, several innovative therapies have been implemented in the treatment of lung cancer that have had reported survival benefits in clinical trials. Whether these improvements translate into the clinic setting has not been studied yet. We retrospectively analyzed all patients consecutively treated at Institute Curie for metastatic lung cancer.

E-Cadherin Mutational Landscape and Outcomes in Breast Invasive Lobular Carcinoma.

Invasive lobular carcinomas (ILC) are characterized by the loss of E-cadherin expression and CDH1 gene inactivation. Diagnostic reproducibility for this tumor type is currently suboptimal and could be improved by a better understanding of its histomolecular and clinical heterogeneity. We have analyzed the relationship between the presence, type, or position of CDH1 mutations, E-cadherin expression, and clinicopathological features (including outcome) in a retrospective series of 251 primary ILC with a long follow-up (median: 9.

Alveolar soft part sarcomas in young patients: The French national NETSARC+ network experience.

Background And Aims: Alveolar soft part sarcoma (ASPS) is an ultra-rare chemo-resistant sarcoma in children, occurring preferentially in young adults. We aimed to describe and compare its clinical presentation and behaviour in children and young adults to determine whether the same therapeutic strategy should be addressed for both populations.

Methods: National retrospective multicentre study of children (0-18 years) vs.
