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…

Progression-free survival (PFS) as a surrogate endpoint for overall survival (OS) in advanced/recurrent gastric cancer (AGC) treatment: Individual-pa…

2020

e16506 Background: In 2013, the GASTRIC (Global Advanced/Adjuvant Stomach Tumor Research through International Collaboration) evaluated the surrogacy of PFS based on IPD of 4,069 patients from 20 randomized trials of AGC. Treatment effects on PFS and on OS were only moderately correlated, and we could not validate PFS as a surrogate endpoint for OS. More recent trials, with refined inclusion criteria and higher standards for evaluating progression, may allow for a more accurate estimate of the correlation. The 2nd round of the GASTRIC sought to re-evaluate the surrogacy of PFS for OS in AGC. Methods: The GASTRIC database was updated with trials published after 2010 which used RECIST (Respo…

2019

Abstract Background Regorafenib prolonged overall survival (OS) versus placebo in patients with treatment-refractory metastatic colorectal cancer (mCRC) in phase III trials. We conducted an observational study of regorafenib for patients with mCRC in real-world clinical practice. Methods The international, prospective, CORRELATE study recruited patients with mCRC previously treated with approved therapies, for whom the decision to treat with regorafenib was made by the treating physician according to the local health authority approved label. The primary objective was safety, assessed by treatment-emergent adverse events (TEAEs; National Cancer Institute Common Terminology Criteria for Adve…

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…

Final results from a randomized phase 3 study of FOLFIRI \pm$ panitumumab for second-line treatment of metastatic colorectal cancer

2013

Abstract: Background: The study 20050181 demonstrated significant improvements in progression-free survival (PFS), objective response, and a nonsignificant trend toward increased overall survival (OS) with panitumumab-FOLFIRI versus FOLFIRI alone for second-line wild-type (WT) KRAS metastatic colorectal cancer (mCRC). Updated long-term data from a prespecified descriptive analysis are reported. Patients and methods: Patients receiving one prior mCRC treatment were randomly assigned (1:1) to panitumumab (6.0 mg/kg)-FOLFIRI versus FOLFIRI every 2 weeks. Co-primary end points (PFS and OS) were prospectively analyzed by tumor KRAS status. Results: One thousand one hundred and eighty-six patient…

Surrogate end points for overall survival and local control in neoadjuvant rectal cancer trials: statistical evaluation based on the FFCD 9203 trial.

2009

Abstract Background In resectable rectal cancer trials, pathological parameters are early preoperative treatment efficacy measures. Their validation as surrogate end points for long-term clinical outcomes would allow to reduce trial duration. The aim was to evaluate potential surrogates for overall survival (OS) and local control (LC) in preoperative T3/T4 rectal cancer trials. Candidate variables included ypT and ypN stages, T downstaging, tumor regression grade (TRG), and circumferential resection margin (CRM) status. Patients and methods In the Federation Francophone de Cancerologie Digestive (FFCD) 9203 trial, 742 eligible patients were randomly assigned to receive preoperative radiothe…

ESMO consensus guidelines for the management of patients with metastatic colorectal cancer

2016

Contains fulltext : 165965.pdf (Publisher’s version ) (Closed access) Colorectal cancer (CRC) is one of the most common malignancies in Western countries. Over the last 20 years, and the last decade in particular, the clinical outcome for patients with metastatic CRC (mCRC) has improved greatly due not only to an increase in the number of patients being referred for and undergoing surgical resection of their localised metastatic disease but also to a more strategic approach to the delivery of systemic therapy and an expansion in the use of ablative techniques. This reflects the increase in the number of patients that are being managed within a multidisciplinary team environment and speciali…

Analysis of KRAS/NRAS mutations in a phase III study of panitumumab with FOLFIRI compared with FOLFIRI alone as second-line treatment for metastatic …

2015

Abstract Purpose: We evaluated the influence of RAS mutation status on the treatment effect of panitumumab in a prospective–retrospective analysis of a randomized, multicenter phase III study of panitumumab plus fluorouracil, leucovorin, and irinotecan (FOLFIRI) versus FOLFIRI alone as second-line therapy in patients with metastatic colorectal cancer (mCRC; ClinicalTrials.gov, NCT0039183). Experimental Design: Outcomes were from the study's primary analysis. RAS mutations beyond KRAS exon 2 (KRAS exons 3, 4; NRAS exons 2, 3, 4; BRAF exon 15) were detected by bidirectional Sanger sequencing in wild-type KRAS exon 2 tumor specimens. Progression-free survival (PFS) and overall survival (OS) we…

2012

3535 Background: The primary analysis of study 20050181 showed that in patients (pts) with wild-type (WT) KRAS mCRC, pmab plus FOLFIRI given as second-line therapy significantly improved progression-free survival (PFS) vs FOLFIRI alone. Here, we report on a prespecified descriptive analysis planned for 30 months (mos) after the last pt was enrolled. Methods: Pts with mCRC, ECOG 0-2, who had one prior fluoropyrimidine-based chemotherapy regimen were randomized 1:1 to pmab 6.0 mg/kg Q2W+FOLFIRI (Arm 1) vs FOLFIRI (Arm 2). Co-primary endpoints were OS and PFS (central assessment). Secondary endpoints included objective response rate (ORR) and safety. Tumor KRAS status was determined by a blin…

Chemotherapy-induced antitumor immunity requires formyl peptide receptor 1.

2015

How dying tumor cells get noticed Besides killing tumor cells directly, some chemotherapies, such as anthracyclines, also activate the immune system to kill tumors. Vacchelli et al. discovered that in mice, anthracycline-induced antitumor immunity requires immune cells to express the protein formyl peptide receptor 1 (FPR1). Dendritic cells (DCs) near tumors expressed especially high amounts of FPR1. DCs normally capture fragments of dying tumor cells and use them to activate nearby T cells to kill tumors, but DCs lacking FPR1 failed to do this effectively. Individuals with breast or colon cancer expressing a variant of FPR1 and treated with anthracyclines showed poor metastasis-free and ov…

2021

Few studies have explored the association between baseline characteristics and the occurrence of early toxicities in patients treated with first-line chemotherapy for metastatic colorectal cancer (mCRC).Individual patient data of 2190 patients enrolled in 10 prospective FFCD (Fédération Francophone de Cancérologie Digestive) trials were analysed. Severe early toxicity was defined as the occurrence of grade ≥III toxicity within 3 months after initiation of chemotherapy (ET3).Patients received monotherapy based on 5-FU (n = 1068), a cytotoxic doublet (n = 395) or tritherapy with a cytotoxic doublet plus anti-VEGF agent or a cytotoxic triplet (n = 727). The patients received 5-FU (100%), Irino…

Abstract Background and scope The management of GOJ cancers remains controversial and may vary between countries. Evidence-based attitudes and guidelines are not easy to elaborate since most of the trials and studies reported mixed cases of oesophageal (both adenocarcinoma and squamous cell tumours), GOJ and gastric cancers. The aim of this expert discussion and position paper is to elaborate practical recommendations that integrate evidence-reported literature and experience-based attitude covering all clinical aspects of GOJ cancer across different specialities and countries in Europe. Methodology Opinion leaders, selected on scientific merit were asked to answer to a prepared set of ques…

Treatment sequence of synchronously (liver) metastasized colon cancer

2016

No standards for staging, systemic therapy or the timing of an operation are defined for patients newly diagnosed with synchronous metastases and a primary in the colon. An expert group of radiologists, medical, radiation and surgical oncologists therefore came together to discuss staging and treatment sequence for these patients and came up with a recommendation based on current evidence of potential therapeutic options. The discussion was organized to debate recommendations centred on 5 topics and therefore the position paper is built upon these titles and their subtitles. Editrice Gastroenterologica Italiana S.r.l.
