Post-Induction Management in Patients With Left-Sided and Wild-Type Metastatic Colorectal Cancer Treated With First-Line Anti-EGFR-Based Doublet Regimens: A Multicentre Study.

Background: Few data regarding post-induction management following first-line anti-epidermal growth factor receptor (EGFR)-based doublet regimens in patients with left-sided wild-type metastatic colorectal cancer (mCRC) are available.

Methods: This multicenter, retrospective study aimed at evaluating clinicians' attitude, and the safety and effectiveness of post-induction strategies in consecutive patients affected by left-sided wild-type mCRC treated with doublet chemotherapy plus anti-EGFR as first-line regimen, who did not experience disease progression within 6 months from induction initiation, at 21 Italian and 1 Spanish Institutions. The measured clinical outcomes were: progression-free survival (PFS), overall survival (OS), adverse events, and objective response rate (ORR).

Reduced-dose of doublet chemotherapy combined with anti-EGFR antibodies in vulnerable older patients with metastatic colorectal cancer: Data from the REVOLT study.

Objectives: To assess the toxicity patterns and effectiveness of doublet chemotherapy when administered at reduced doses of 20% (FOLFOX or FOLFIRI) in combination with anti-EGFR antibodies (cetuximab or panitumumab) in old, vulnerable patients with metastatic colorectal cancer (mCRC).

Patients And Methods: We performed a retrospective observational study of RAS and BRAF wild-type, vulnerable patients aged ≥70 years with previously untreated mCRC. The primary endpoint was safety, and secondary endpoints were overall response rate (ORR), progression-free survival (PFS), and overall survival (OS).

Clinicians' Attitude to Doublet Plus Anti-EGFR Versus Triplet Plus Bevacizumab as First-line Treatment in Left-Sided RAS and BRAF Wild-Type Metastatic Colorectal Cancer Patients: A Multicenter, "Real-Life", Case-Control Study.

Background: Doublets plus antiepidermal growth factor receptors monoclonal antibodies (EGFRi) are widely considered the preferable first-line regimen in patients with left-sided RAS/BRAF wild-type metastatic colorectal cancer (mCRC), resulting superior in terms of activity and efficacy compared to doublets plus bevacizumab. However, data comparing doublet plus EGFRi and triplet plus bevacizumab are lacking, and the relative benefit of an intensive regimen plus an antiangiogenic backbone in this population is debated.

Methods: This multicenter, retrospective study aimed at evaluating clinicians' attitude to triplet-bevacizumab and doublet-EGFRi as first-line regimen in patients with left-sided RAS/BRAF wild-type mCRC treated in clinical practice at 22 Oncology Units from March 2012 to October 2020.

Effect of Bevacizumab in Combination With Standard Oxaliplatin-Based Regimens in Patients With Metastatic Colorectal Cancer: A Randomized Clinical Trial.

Importance: Although bevacizumab is a standard of care in combination treatments for metastatic colorectal cancer (mCRC), its clinical benefit has been limited.

Objective: To determine whether sequential scheduling of bevacizumab administration in combination with chemotherapy improves treatment efficacy in patients with mCRC, in keeping with the tumor vascular normalization hypothesis.

Design, Setting, And Participants: This open-label, randomized clinical phase 3 trial was conducted from May 8, 2012, to December 9, 2015, at 3 Italian centers.

Assessing the benefit of cancer drugs approved by the European Medicines Agency using the European Society for Medical Oncology Magnitude of Clinical Benefit Scale over time.

Background: Increasingly, cancer drugs are being approved based on surrogate measurements of efficacy. Clinically meaningful data, such as overall survival (OS) and quality of life, are often only presented in subsequent publications. We examined if the clinical benefit of cancer drugs, as measured by the European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS), improves post-European Medicines Agency (EMA) approval as more data emerges.

Oxaliplatin plus fluoropyrimidines as adjuvant therapy for colon cancer in older patients: A subgroup analysis from the TOSCA trial.

Background: Previous studies on oxaliplatin and fluoropyrimidines as adjuvant therapy in older patients with stage III colon cancer (CC) produced conflicting results.

Patients And Methods: We assessed the impact of age on time to tumour recurrence (TTR), disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) in 2360 patients with stage III CC (1667 aged <70 years and 693 ≥ 70 years) randomised to receive 3 or 6 months of FOLFOX or CAPOX within the frame of the phase III, TOSCA study.

Results: Older patients compared with younger ones presented more frequently an Eastern Cooperative Oncology Group performance status equal to 1 (10.

RAS as a positive predictive biomarker: focus on lung and colorectal cancer patients.

Rat sarcoma (RAS) oncogenes have intensively been investigated during the last decades. Taking into account all human tumours, Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) gene is the most frequently mutated (about 22%) among the three isoforms, followed by Neuroblastoma RAS Viral Oncogene Homolog (NRAS) (8%) and Harvey Rat Sarcoma Viral Oncogene Homolog (HRAS) (3%). In the last years, careful attention has been paid on KRAS and NRAS gene mutations in non-small-cell lung cancer (NSCLC) and colorectal cancer (CRC) patients because of their prognostic and predictive roles.

Germinal BRCA1-2 pathogenic variants (gBRCA1-2pv) and pancreatic cancer: epidemiology of an Italian patient cohort.

Objective: Germline BRCA1-2 pathogenic variants (gBRCApv) increase the risk of pancreatic cancer and predict for response to platinating agents and poly(ADP-ribose) polymerase inhibitors. Data on worldwide gBRCApv incidence among pancreatic ductal adenocarcinoma (PDAC) patients are sparse and describe a remarkable geographic heterogeneity. The aim of this study is to analyze the epidemiology of gBRCApv in Italian patients.

Randomized phase II study of valproic acid in combination with bevacizumab and oxaliplatin/fluoropyrimidine regimens in patients with -mutated metastatic colorectal cancer: the REVOLUTION study protocol.

Background: Despite effective treatments, metastatic colorectal cancer (mCRC) prognosis is still poor, mostly in -mutated tumors, thus suggesting the need for novel combinatorial therapies. Epigenetic alterations play an important role in initiation and progression of cancers, including CRC. Histone-deacetylase inhibitors (HDACi) have shown activity in combination with chemotherapy in the treatment of solid tumors.
