title: The impact of the introduction of irinotecan and oxaliplatin on the outcome of patients with advanced colorectal cancer.
abstract: The effectiveness of oxaliplatin and irinotecan in advanced colorectal cancer therapy has been shown by many randomized clinical trials. We developed a retrospective study on patients treated in the clinical practice. The main inclusion criteria were: diagnosis of unresectable colorectal adenocarcinoma and having undergone chemotherapy. Univariate and multivariate analyses were performed to identify the prognostic factors of survival. The study included 286 consecutive patients. Three factors were associated with worse survival: high CA19-9 levels (p=0.003), schedules without new regimens (p=0.031) and weight loss (p=0.070). The use of new regimens was associated with a significant improvement in median survival (15 to 10 months, p<0.001). Although the new regimens improved survival in clinical practice, the median gain is smaller than that reported in randomized trials. The palliative intent of these therapies should not be forgotten in order to improve quality of life rather than absolute survival.
