Abstract

Objective To investigate the clinical efficacy of three-dimensional conformal radiotherapy combined with XELOX program chemotherapy in the treatment of postoperative local recurrence of rectal cancer.Methods One hundred and twenty-nine patients with postoperative local recurrence of rectal cancer were divided by random digits table method into treatment group (65 cases) and control group (64 cases).The patients in treatment group were treated with three-dimensional confonmal radiotherapy combined with XELOX program chemotherapy.The patients in control group were treated with XELOX program chemotherapy.The short-term effect,symptom control rate,long-term efficacy and adverse reaction were observed.Results The efficiency rate in treatment group [ 90.8％ (59/65) ] was significantly higher than that in control group [ 73.4％(47/64) ] (P ＜ 0.05 ).The improvement rates of pain,hematochezia and incomplete obstruction between treatment group and control group had significantly statistical differences [95.2％(40/42) vs.75.0％(27/36),92.9％(26/28) vs.79.5％(31/39),94.7％(18/19) vs.75.0％(9/12)](P ＜0.05).The 1,2,3-year survival rates between treatment group and control group had significantly statistical differences [ 67.7％ ( 42/62 ) vs.43.5 ％ ( 27/62 ),53.2％ ( 33/62 ) vs.30.6％ ( 19/62 ),38.7％ ( 24/62 )vs.14.5％ (9/62)] (P ＜ 0.01 ).The adverse reaction in two groups were mainly bone marrow suppression,gastrointestinal reactions,hand-fcot syndrome and radiation cystitis.The incidence rate of adverse reaction in treatment group was slightly higher than that in control group,but there was no significant difference between two groups (P ＞ 0.05).Conclusion Three-dimensional conformal radiotherapy combined with XELOX program chemotherapy in patients with postoperative local recurrence of rectal cancer can improve the short-term effect,symptom control rate and long-term survival rate.
