ABSTRACT
OBJECTIVE:To observe clinical efficacy and safety of capecitabine and tegafur gimeracil and oteracil potassium synchronous radiotherapy in the treatment of recurrence after radical resection of colon cancer. METHODS:A total of 150 patients with recurrent after radical resection of colon cancer in our hospital during Jan. 2012-Dec. 2012 were divided into group A and B ac-cording to random number table,with 75 cases in each group. Both groups received three-dimensional conformal radiotherapy. Group A was additionally given capecitabine 2.5 g. Group B was additionally given tegafur gimeracil and oteracil potassium,40 mg,bid for body surface area <1.25 m2,50 mg,bid for body surface area ranged 1.25-1.50 m2 and60mg,bid for body surface ar-ea<1.50 m2. Clinical efficacies of 2 groups were compared;1-year,2-year,3-year survival andⅢ-Ⅳdegree toxic effect were fol-lowed up. RESULTS:The total response rate of group B was 86.67％,which was significantly higher than 66.67％ of group A, with statistical significance(P<0.05). 1-year,2-year,3-year survival rates of group B were 93.335,72.00％,58.67％,which was significantly higher than 74.67％,53.33％,41.33％,with statistical significance(P<0.05). The median disease progression time of group A was 8.0 months,which was significantly shorter than 9.5 months of group B,with statistical significance (P<0.05). There was no statistical significance in Ⅲ-Ⅳ degree toxic effect between 2 groups (P<0.05). CONCLUSIONS:Compared with capecitabine,tegafur gimeracil and oteracil potassium combined with three-dimensional conformal radiotherapy show significant therapeutic efficacy for recurrence after radical resection of colon cancer,can control disease progression,prolong the survival time and don't increase the risk of toxic effects.
