OBJECTIVES:
* To assess the prevalence of delayed nausea and vomiting in patients with colorectal cancer receiving standard anti-emetic medications during the first course of an oxaliplatin-based chemotherapy regimen (mFOLFOX6 or FOLFOX7).
OUTLINE: This is a multicenter study.
Patients undergo collection of demographic, diagnostic, and treatment data at baseline. Patients complete the Functional Living Index-Emesis (FLIE) questionnaire at baseline prior to first chemotherapy infusion and at 5-7 days. Patients also fill out daily patient diaries about symptoms of nausea and vomiting, and use of medications to prevent these symptoms over days 1-5.
