Impact of Baseline Covariates and Prior Therapy on the Efficacy of Second-Line Panitumumab (Pmab) + Folfiri Vs Folfiri Treatment
2014
ABSTRACT Aim: Expanding RAS analyses beyond KRAS exon 2 is important in selecting patients (pts) for pmab treatment. Here we present prespecified subgroup analyses from a phase 3 randomised second-line pmab + FOLFIRI vs FOLFIRI study in metastatic colorectal cancer (mCRC) pts. Methods: Progression-free (PFS) and overall survival (OS) were co-primary endpoints. KRAS exon 2 wild-type (WT) samples were tested for mutations in KRAS exons 3/4, NRAS exons 2/3/4 and BRAF exon 15 via bidirectional Sanger sequencing and WAVE-based SURVEYOR®. PFS and OS subgroup analyses were performed by randomisation stratification factors (ECOG performance status [PS], prior bevacizumab [bev]/prior oxaliplatin [ox…
New findings on primary and acquired resistance to anti-EGFR therapy in metastatic colorectal cancer: Do all roads lead to RAS?
2015
Abstract: Anti-epidermal growth factor receptor therapy with the monoclonal antibodies cetuximab and panitumumab is the main targeted treatment to combine with standard chemotherapy for metastatic colorectal cancer. Many clinical studies have shown the benefit of the addition of these agents for patients without mutations in the EGFR pathway. Many biomarkers, including KRAS and NRAS mutations, BRAF mutations, PIK3CA mutations, PTEN loss, AREG and EREG expression, and HER-2 amplification have already been identified to select responders to anti-EGFR agents. Among these alterations KRAS and NRAS mutations are currently recognized as the best predictive factors for primary resistance. Liquid b…
Tumour Shrinkage and Response Outcomes During Second-Line Panitumumab (Pmab) + Folfiri Vs Folfiri Treatment
2014
ABSTRACT Aim: Tumour shrinkage/response are important outcomes for patients (pts) with metastatic colorectal cancer (mCRC) as they may delay progression and ultimately improve survival. Here we report tumour response data for pts with RAS WT mCRC treated with FOLFIRI ± pmab. Methods: 181 was a phase 3 randomised study of second-line pmab + FOLFIRI vs FOLFIRI alone in pts with previously treated mCRC. KRAS exon 2 wild-type (WT) samples from this study were tested for mutations in KRAS exons 3/4 and NRAS exons 2/3/4 via bidirectional Sanger sequencing and WAVE-based SURVEYOR® to identify pts with RAS WT tumours (no mutations in KRAS/NRAS exons 2, 3 or 4). Objective response rates (ORRs) and m…

Update on capecitabine alone and in combination regimens in colorectal cancer patients
2010
Capecitabine is an orally administered fluoropyrimidine carbamate which has been developed as a prodrug of 5-FU with the goal to improve its tolerability and intratumoral drug concentration. The review aims to provide an evidence-based update of clinical trials investigating the clinical efficacy, adverse-event profile, dosage and administration of this drug, alone or in combination with conventional chemotherapeutics and/or new target-oriented drugs, in the management of colorectal cancer patients. © 2010 Elsevier Ltd.

Intraoperative Adjuvant Hyperthermic Intraperitoneal Chemotherapy in Patients with Locally Advanced Colon Cancer: A Prospective Parallel Phase II Stu…
2020
.Background: Prophylactic hyperthermic intraperitoneal chemotherapy (HIPEC) showed promising results in patients with colorectal carcinoma at high risk of recurrence but still without clinically and radiologically evident signs of peritoneal spread. This study aims to analyze the feasibility of this proactive, early phase, multimodality approach. Methods: A mono-institutional, prospective, parallel, two-stage phase II trial enrolled 49 patients to standard surgery or surgery plus intraoperative HIPEC. Before the procedure and during surgery, patients received intravenous fluorouracil (and leucovorin to potentiate oxaliplatin activity. Data analysis included length of hospital stay, surgery …

Quality of Life in Patients With Severe Skin Reactions in Course of First-Generation Epidermal Growth Factor Receptor Inhibitors Monoclonal Antibodie…
2021
Background: Metastatic colorectal cancer (mCRC) with wild type expression of RAS and RAF genes can be treated with anti-epidermal growth factor receptor (EGFR) monoclonal antibodies, such as cetuximab, in combination with chemotherapy. Skin toxicity represents the most serious and frequent side effect in these patients. Skin manifestations occur in approximately 80% of patients. In this study, we investigated the consequences on body image and quality of life (QoL) of patients with severe skin toxicity. Methods: One hundred patients were enrolled with mCRC. All patients signed informed consent and completed questionnaires to assess QoL and body discomfort. Toxicity was assessed on Common Te…
