Phase III randomized study of oxaliplatin, leucovorin

in patients with resected Stage II colon cancer
Protocol ID: ECOG-E5202
Target Accrual: 3,610 (Open)
FOLFOX
Eligibility
Stage II (T3-4, N0, M0)
with paraffinembedded tumor
specimen available

bevacizumab
Observation
* Patients are stratified according to disease stage (IIA versus IIB), microsatellite
stability status (microsatellite stable [MSS] or microsatellite instable [MSI]) and
presence or absence of heterozygosity at chromosome 18q. Patients deemed to
be at high risk based on these molecular parameters are randomly assigned to
one of two treatment arms (arms I and II), whereas patients at low risk are
assigned to arm III.
