title: [Efficacy and toxicity analysis of XELOX and FOLFOX4 regimens as adjuvant chemotherapy for stage III colorectal cancer].
abstract: OBJECTIVE
  To compare the efficacy and toxicity of capecitabine plus oxaliplatin (XELOX) versus 5-fluorouracil/leucovorin (5-Fu/LV) plus oxaliplatin (FOLFOX4) regimens as adjuvant chemotherapy for stage III colorectal cancer.
  
  
  METHODS
  The clinicopathological data of 118 patients with stage III colorectal cancer were studied retrospectively. The patients were assigned to receive either FOLFOX4 regimen (n = 76) or XELOX regimen (n = 42). 3-year disease-free survival (DFS) and adverse events as end points were compared between the two groups.
  
  
  RESULTS
  The number of patients that failed to finish 8 cycles was higher in FOLFOX4 group (28 vs. 8, P = 0.044). There was no significant difference for 3-year DFS and all grades adverse events between the two groups. However, the FOLFOX4 group showed more grade 3/4 neutropenia (31.6% vs. 14.3%, P = 0.039) and central venous catheter-associated complication (11.8% vs. 4.8%, P = 0.205), while XELOX showed more grade 3/4 thrombocytopenia (19.0% vs. 6.6%, P = 0.038) and hand-foot syndrome (11.9% vs. 1.3%, P = 0.012).
  
  
  CONCLUSIONS
  The results of this analysis indicate that XELOX and FOLFOX4 regimens have very similar efficacy as an adjuvant chemotherapy for stage III colon cancer, but XELOX may be safer than FOLFOX4.
