Gender-Based Differences in the Efficacy of Anti-EGFR/BRAF/MEK Targeted Therapy in Patients with BRAF-Mutated Metastatic Colorectal Cancer.

Objectives: We previously showed that men with melanoma harboring BRAF mutations had significantly lower benefit from targeted therapy as compared with women Here we explored the hypothesis that such gender-based dimorphism in the efficacy of BRAF-pathway blockade extends to other tumor histotypes carrying pathogenic BRAF-mutations.

Methods: We retrospectively analyzed data from a cohort of patients with advanced colorectal-cancer (CRC) harboring BRAF V600E mutations, treated with anti-EGFR/BRAF/MEK targeted therapy. The primary objective was to assess the association between gender and outcome of patients treated with targeted therapy, in terms of overall response rate (ORR), progression-free survival (PFS) and overall survival (OS).

Estrogen Signaling in Early-Stage Breast Cancer: Impact on Neoadjuvant Chemotherapy and Immunotherapy.

Neoadjuvant chemoimmunotherapy (NACIT) has been shown to improve pathologic complete response (pCR) rates and survival outcomes in stage II-III triple-negative breast cancer (TNBC). Promising pCR rate improvements have also been documented for selected patients with estrogen receptor-positive (ER+) human epidermal growth factor receptor 2-negative (HER2-) breast cancer (BC). However, one size does not fit all and predicting which patients will benefit from NACIT remains challenging.

Outcomes of patients with advanced solid tumors who discontinued immune-checkpoint inhibitors: a systematic review and meta-analysis.

Background: The outcome of patients with metastatic tumors who discontinued immune checkpoint inhibitors (ICIs) not for progressive disease (PD) has been poorly explored. We performed a meta-analysis of all studies reporting the clinical outcome of patients who discontinued ICIs for reasons other than PD.

Methods: We searched PubMed, Embase and Scopus databases, from the inception of each database to December 2023, for clinical trials (randomized or not) and observational studies assessing PD-(L)1 and CTLA-4 inhibitors in patients with metastatic solid tumors who discontinued treatment for reasons other than PD.

Surrogate endpoints for overall survival in randomized clinical trials testing immune checkpoint inhibitors: a systematic review and meta-analysis.

Introduction: There is debate on which are the best surrogate endpoint and metric to capture treatment effect on overall survival (OS) in RCTs testing immune-checkpoint inhibitors (ICIs).

Methods: We systematically searched for RCTs testing ICIs in patients with advanced solid tumors. Inclusion criteria were: RCTs i) assessing PD-(L)1 and CTLA-4 inhibitors either as monotherapy or in combination with another ICI, and/or targeted therapy, and/or chemotherapy, in patients with advanced solid tumors; ii) randomizing at least 100 patients.
