摘要
目的探讨直肠癌术后局部复发的原因和三维适形放疗的治疗作用。方法回顾性分析1996年1月～2006年6月接受放射治疗的57例直肠癌术后盆腔内复发病例,其中18例患者仅接受常规外照射(常规组),39例接受了适形放疗(适形组),比较两组治疗结果。结果肿瘤局控(CR+PR)率和止痛有效率适形组均略高于常规组(71.80%:55.50%和94.90%:88.90%),P>0.05;放射致腹泻发生率适形组低于常规组,P<0.01。中位生存期适形放疗组高于常规组[(33.00±5.54)个月:(21.00±3.82)个月],P<0.05。结论三维适形放疗作为直肠癌术后盆腔内复发的治疗手段之一,在提高肿瘤控制率和生存率、减轻放疗损伤作用方面优于传统放疗,但仍需进一步研究。
Objective To discuss facilitated factors of postoperation recurrence of rectum cancer and the treatment effect of 3-DCRT for locally recurrent rectal cancer.Methods57 patients with pelvic recurrent rectal cancer underwent radiotherapy during Jan.1996 to Jun.2006, and their data was reviewed.39 of them received 3-DCRT and 18 received conventional radiotherapy only, and outcomes were compared.ResultsPatients who received 3-DCRT had tumor-controlled(CR+PR) and pain-killed more often(71.80% vs 55.50% and 94.90%...
