title: [Efficacy and side effects of combination therapy of oxaliplatin and S-1 for colorectal cancer].
abstract: OBJECTIVE
  To observe the efficacy and side effects of the combination therapy of oxaliplatin and S-1 in treating postoperative colorectal cancer patients.
  
  
  METHODS
  54 postoperative colorectal cancer patients received the combination therapy of oxaliplatin and S-1 regimen, repeated every 3 weeks, and evaluate the efficacy after 3 cycles.
  
  
  RESULTS
  All of the 54 patients but 2 (changed the chemotherapy regimen after the first cycle because of economic reason) finished 6 cycles of the chemotherapy treatment. There were 6 cases (11.5%) with complete response (CR), 28 cases (53.8%) with partial response (PR), and the overall response rate was 65.4%. Major adverse effects were hematological toxicities, gastrointestinal disturbance, neurosensory toxicity. There were no chemotherapy-related deaths.
  
  
  CONCLUSIONS
  Oxaliplatin combined with S-1 is an effective and better tolerated chemotherapy treatment for postoperative colorectal cancer patients, with no serious side effects for liver and kidney. Therefore, it can be used as an alternative chemotherapy regimen for postoperative colorectal cancer patients.
