直肠癌患者术后常规放疗与三维适形放疗的有效性及安全性对比分析

Comparative analysis of the efficacy and safety of postoperative conventional radiotherapy and 3D conformal radiotherapy in patients with rectal cancer

目的:探讨直肠癌患者术后常规放疗与三维适形放疗的有效性及安全性。方法:2018年3月-2019年5月收治直肠癌患者98例,随机分为两组,各49例。参照组运用常规放疗方案;观察组运用三维适形放疗方案。比较两组临床疗效及不良症状存在率。结果:观察组治疗总有效率高于参照组,不良症状存在率显著低于参照组,差异有统计学意义(P<0.05)。结论:在直肠癌患者术后放疗中选用三维适形放疗方案,有效率高,安全性高。

Objective:To investigate the efficacy and safety of postoperative conventional radiotherapy and 3D conformal radiotherapy in patients with rectal cancer.Methods:From March 2018 to May 2019,98 patients with rectal cancer were enrolled,they were randomly divided into two groups with 49 cases in each group.The reference group used conventional radiotherapy.The observation group used 3D conformal radiotherapy.The clinical efficacy and incidence of adverse symptoms between the two groups were compared.Results:The total effective rate of treatment in the observation group was higher than the reference group,the incidence of adverse symptoms was significantly lower than the reference group,the differences were statistically significant(P<0.05).Conclusion:Three-dimensional conformal radiotherapy is used in postoperative radiotherapy for rectal cancer patients,it has high efficiency and safety.
