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

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…

TH-302 + Gemcitabine (G + T) vs Gemcitabine (G) in Patients with Previously Untreated advanced Pancreatic Cancer (PAC)

ABSTRACT Background TH-302 is a hypoxia targeted prodrug with a hypoxia-triggered 2-nitroimidazole component designed to release the DNA alkylator, bromo-isophosphoramide mustard (Br-IPM), when reduced in severe hypoxia. A randomized Phase 2B study (NCT01144455) was conducted to assess the benefit of G + T to standard dose G as first-line therapy of PAC. Materials and methods An open-label multi-center study of two dose levels of TH-302 (240 mg/m2 or 340 mg/m2) in combination with G versus G alone (randomized 1:1:1). G (1000 mg/m2) and T were administered IV over 30-60 minutes on Days 1, 8 and 15 of a 28-day cycle. Patients on the G could crossover after progression and be randomized to a G…

Perioperative FOLFOX 4 Versus FOLFOX 4 Plus Cetuximab Versus Immediate Surgery for High-Risk Stage II and III Colon Cancers: A Phase II Multicenter Randomized Controlled Trial (PRODIGE 22).

BACKGROUND Perioperative chemotherapy has proven valuable in several tumors, but not in colon cancer (CC). OBJECTIVE The aim of this study was to evaluate the efficacy and safety of perioperative chemotherapy in patients with locally advanced nonmetastatic CC. METHODS This is a French multicenter randomized phase II trial in patients with resectable high-risk T3, T4, and/or N2 CC on baseline computed tomography (CT) scan. Patients were randomized to receive either 6 months of adjuvant FOLFOX after colectomy (control) or perioperative FOLFOX for 4 cycles before surgery and 8 cycles after (FOLFOX peri-op). In RAS wild-type patients, a third arm testing perioperative FOLFOX-cetuximab was added…

Cancer du pancréas localement évolué non resécable : chimioradiothérapie d’induction suivie de chimiothérapie par gemcitabine contre chimiothérapie exclusive par gemcitabine : résultats définitifs de l’étude de phase III 2000–2001de la FFCD et de la SFRO

Resume Objectif de l’etude Etudier l’apport de la chimioradiotherapie concomitante suivie de chimiotherapie dans le cancer pancreatique localement evolue, par rapport a la chimiotherapie seule. Patients et methodes Cent dix-neuf patients atteints d’un cancer pancreatique localement evolue, avec indice de performance de 0 a 2 selon l’Organisation mondiale de la sante, ont ete randomises entre une chimioradiotherapie concomitante d’induction (60 Gy, 2 Gy/fraction ; perfusion concomitante de 5-fluoro-uracile de 300 mg/m2 par jour, de j1 a j5 pendant six semaines ; cisplatine, 20 mg/m2 par jour, de j1 a j5 pendant la premiere et la cinquieme semaines) et une chimiotherapie d’induction par gemci…
