Is irinotecan better than oxaliplatin?
The response rate of oxaliplatin group was higher than that of irinotecan group (relative risk (RR) = 0.82, 95% confidence interval (95%CI) (0.70, 0.96), P = 0.01), and the median overall survival of oxaliplatin group was longer by 2.04 months than that of irinotecan group (95%CI (-3.54, -0.54), P = 0.008).

Why is oxaliplatin given before irinotecan?
Oxaliplatin-based first-line chemotherapy is associated with improved overall survival compared to first-line treatment with irinotecan-based chemotherapy in patients with metastatic colorectal cancer – results from a prospective cohortstudy. Clin Epidemiol. 2015;7:295–303.
Can irinotecan be given before oxaliplatin?
Our study suggested that irinotecan followed by oxaliplatin-based regimens might be a better chemotherapy treatment option for metastatic colorectal cancer than the reverse sequence given the higher crossover rate and potential overall survival benefit.
