Abstract
Objective: The aim of this study was to explore the three-dimensional conformal radiotherapy combined with FOLFOX scheme chemotherapy in the treatment of postoperative recurrence of rectal cancer. Methods: Sixty-eight cases of recurrent rectal cancer were divided randomly into two groups: 34 cases of conformal radiotherapy plus FOLFOX chemotherapy group (experiment group) and 34 cases of conformal radiotherapy (control group). After 6 MvX line with three-dimensional conformal radiotherapy technologies for recurrent lesions and pelvic cavity around subclinical lymphatic drainage radiotherapy after radiotherapy to DT 40 Gy to reposit was made use of between both groups, experiment group was made the new treatment plan to continue to irradiate to 50 Gy, and then Shrinkage GTV was pushed quantity in the field 66 Gy. Researchers took chemotherapy in the first week and the fourth week after radiotherapy, with 5-fluorouracil 500 mg/m2, calcium leucovorin 200 mg, d1-5 with intravenous drip, Oxaliplatin 130 mg/m2 and d1 with intravenous drip 2 h, 21 days was one cycle. Kaplan-Meier method was used for survival analysis. Results: The survival rates for 1, 2 and 3 years for experiment group and control group were 88.2%, 64.7%, 47.1% and 66.7%, 38.2%, 29.4% (P = 0.03), the 2-year rate of distant metastases was 32.4% and 58.8% (P = 0.032) respectively. The median survival time was 33 and 20 months respectively. There were some side effects between the groups, but there was no statistical difference. Conclusion: Three-dimensional conformal radiotherapy plus FOLFOX chemotherapy can be considered as a safe and effective approach to treat rectal cancer patients of postoperative recurrence, and can improve the survival rates of patients and reduce distant metastasis rate obviously and make the acute adverse reaction rate insignificantly.关键词
