Background: Triplet chemotherapy plus cetuximab showed promising results in phase II trials in unsystematically selected RAS population. We evaluated FOLFIRINOX+cetuximab efficacy as first-line treatment in extended RAS wild-type metastatic colorectal cancer (mCRC) patients.
Methods: We retrospectively analyzed patients treated with FOLFIRINOX+cetuximab, using data from clinical trials and real-life practice.
Introduction: Preoperative anxiety is a frequent problem that can lead to complications both during anaesthesia and in the postoperative period, especially in oncology. Studies have shown that it can be managed using non-pharmacological approaches, but few works have evaluated psychoeducational programmes. The aim of the COHErence Cardiaque (COHEC) II Study is to evaluate the combination of medical hypnosis (MH) and cardiac coherence (CC) training to manage preoperative anxiety in patients with cancer.

- The study aims to investigate the relationship between treatment response to neoadjuvant chemoradiotherapy (CRT) and intestinal microbiota, particularly focusing on Colibactin-producing E. coli (CoPEC), in patients with mid and low rectal cancer.
- A prospective clinical study involving 200 patients will collect and analyze stool samples at different stages of treatment to evaluate microbiota composition and detect CoPEC, while also assessing tumour response and survival outcomes.
- The research has ethical approval and aims to identify factors that could help tailor treatment strategies for rectal cancer patients.
Purpose: Circulating cell-free DNA (ccfDNA) is a valuable source of tumor material obtained from a simple blood sampling that enables noninvasive analysis of the tumor genome. Our goal was to carry out a multiparametric analysis of ccfDNA and evaluate its prognostic value by investigating the overall survival (OS) of 97 metastatic colorectal cancer patients (mCRC).
Experimental Design: Qualitative parameters (determination of the main KRAS exon2 and BRAF V600E mutations) and quantitative parameters (total ccfDNA concentration, mutant ccfDNA concentration, the proportion of mutant ccfDNA, and ccfDNA integrity index) were determined simultaneously in a single run using a unique Q-PCR multimarker approach (100% success rate).
The aim of this study was to measure the inter-observer agreement between two teams of three dermatologists and oncologists in labelling and grading the cetuximab-induced dermatological toxicities from 98 photographs performed in a cohort of 15 patients with metastatic colorectal cancer receiving cetuximab-based chemotherapy. Kappa coefficient (κ) assessed inter-observer grading agreement. Both teams defined by the same terms eight of the 13 (62%) toxic effects reported together.
