Pharmacogenomics of cetuximab in metastatic colorectal carcinoma
2014
Cetuximab is a chimeric monoclonal antibody that has revolutionized the treatment of metastatic colorectal cancer. Knowledge of the mechanisms that underlie its effectiveness, as well as the primary and secondary resistance mechanisms, have led to important developments in the understanding of cetuximab biology. In light of knowledge gained from recent trials, the efficacy of cetuximab has been clearly demonstrated to depend upon RAS mutational status, moreover cetuximab should only be used in a subset of patients who may benefit. In this article, we critically review clinical and pharmacogenetic issues of cetuximab, focusing on the cost–effectiveness involved with the use of the drug.

e20724 Background: Anti-EGFR empowered chemotherapeutic regimens resulted in increased overall survival (OS) and response rates (RR). Anti-EGFR induced skin rash occurs in ~ 70% patients, and ~18% ...

3586 Background: The oral multikinase inhibitor Sorafenib (S) inhibits angiogenesis and tumor growth in preclinical models of CRC. This study investigated the addition of S to standard 2nd line chemotherapy (CTX). Methods: Patients (pts) with mCRC and progression after first-line therapy with an oxaliplatin- or irinotecan based fluoropyrimidine containing regimen ± Bevacizumab (Bev), were randomized to receive chemotherapy (CTX) (FOLFOX6 or FOLFIRI) + S (400 mg bid) or CTX + placebo (P). 240 pts were planned to be enrolled to ensure a power of 80% if median progression-free survival (PFS) with S is increased by 2 months compared to P. Results: Between 04/09 and 10/11, 101 pts were enrolled…

Liquid Biopsy in Colorectal Cancer
2017
Colorectal cancer (CRC) is the third most common cancer worldwide. Oncological CRC treatment is changing gradually replacing ancient drugs with the newest targeted agents (target therapy) and immunotherapy. The correct use of these molecular agents is based on a series of genetic evaluations able to predict treatment response. The tissue evaluation of these predictors is generally fully of serious limitations among which the invasiveness of the tissue biopsy procedure and its non-informative quality compared to the entire neoplastic mass. For these reasons, liquid biopsy could represent an ideal tool to obtain easily and quickly the necessary information to decide the best therapeutic strat…
Monoclonal antibodies in gastrointestinal cancers
2013
Introduction: Among gastrointestinal cancers, colorectal and gastric neoplasms are the most frequent. The development of new targeted drugs improved the efficacy of systemic therapy in advanced stages of those malignancies. Areas covered: This review highlights the main biological processes implicated in gastrointestinal cancer development and progression, such as angiogenesis and epidermal growth factor receptor (EGFR) signaling pathway. On these bases, anti-EGFR and anti-vascular endothelial growth factor (VEGF) monoclonal antibodies in colorectal and gastric cancer are discussed. Data about further monoclonal antibodies in development are also reported. Expert opinion: The use of monoclo…
The prevalent KRAS exon 2 c.35 G > A mutation in metastatic colorectal cancer patients: a biomarker of worse prognosis and potential benefit of bevac…
2015
Bevacizumab-containing chemotherapy differently predict increased efficacy in KRAS exon 2 mutant and wild-type metastatic colorectal cancer (MCRC) patients. Mutant compared to wild-type status did not significantly affect progression-free survival (PFS) and overall survival (OS) in patients fit for first line bevacizumab-containing FIr-B/FOx regimen, and after progression. In patients unfit for intensive regimens, mutant status significantly affected PFS, while not OS. Codon 12 KRAS mutations differentially affect GTPase function, and confer worse clinical behaviour. Prognostic relevance of the prevalent c.35 G. >. A KRAS mutation was retrospectively evaluated. Fit c.35 G. >. A mutant patie…
Dilemma in metastatic colorectal cancer: VEGF versus EGRF targeting
2013
Abstract: The modern approach for metastatic colorectal cancer (mCRC) patients is based on the identification of oncogenic pathways, which could be targeted by specific molecules. Vascular endothelial growth factor (VEGF)- and epithelial growth factor receptor (EGFR)-related pathways represent the most important biological mechanisms for cancer development and progression. However, the most significant results by VEGF and EGFR targeting could be achieved through the combination of these drugs with standard chemotherapeutic regimens. These strategies aim to improve the resectability of liver and lung metastases. For those patients who cannot be eligible for metastases resection, a 'continuum…
