The addition of oxaliplatin to the mayo clinic schedule significantly increases its toxicity: a retrospective analysis of patients with advanced colorectal cancer

Background Oxaliplatin has been introduced to the clinical setting in combination with 5-fluorouracil/folinic acid (5-FU/FA) in an attempt to improve the response rate against colorectal cancer. It is unclear the optimum schedule of combination. In order to evaluate the response rate and toxicity profile of the combination of oxaliplatin with 5-FU/FA, according to the Mayo Clinic schedule, we evaluated our patients in a retrospective analysis.
