Résumé
OBJECTIVE: To assess the impact of primary tumour resection on overall survival (OS) of patients diagnosed with stage IV colorectal cancer (CRC). DESIGN: Among the 294 patients with non-resectable colorectal metastases enrolled in the Federation Francophone de Cancerologie Digestive (FFCD) 9601 phase III trial, which compared different first-line single-agent chemotherapy regimens, 216 patients (73%) presented with synchronous metastases at study entry and constituted the present study population. Potential baseline prognostic variables including prior primary tumour resection were assessed by univariate and multivariate Cox analyses. Progression-free survival (PFS) and OS curves were compared with the logrank test. RESULTS: Among the 216 patients with stage IV CRC (median follow-up, 33 months), 156 patients (72%) had undergone resection of their primary tumour prior to study entry. The resection and non-resection groups did not differ for baseline characteristics except for primary tumour location (rectum, 14% versus 35%; p=0.0006). In multivariate analysis, resection of the primary was the strongest independent prognostic factor for PFS (hazard ratio (HR), 0.5; 95% confidence interval [CI], 0.4-0.8; p=0.0002) and OS (HR, 0.4; CI, 0.3-0.6; p
