胆管癌三维适形放射治疗疗效观察

目的观察三维适形放射治疗胆管癌的疗效。方法用三维适形放射治疗方法治疗胆管癌21例,观察疗效和并发症。结果肿瘤局部控制率为52.38%(11/21)。1、2、3年生存率分别是42.85%(9/21)、28.57%(6/21)、14.29%(3/21)。中位生存期16.5个月(2~38个月)。放疗后晚期,8例患者出现十二指肠溃疡,4例死于上消化道出血。结论三维适形放射治疗胆管癌可以达到姑息治疗的目的,控制放疗后并发症的发生是提高患者生存率的关键。

Therapeutic effect of three-dimensional conformal radiotherapy on hilar cholangiocarcinoma

Objective To evaluate the therapeutic effects of three-dimensional conformal radiotherapy (3D-CRT) for hilar cholangiocarcinoma. Methods Twenty-one patients with unresectable hilar cholangiocarcinoma were treated with 3D-CRT and the acute effects and survival rates were observed. Results Eleven (52.38%) of the 21 patients achieved a complete or partial remission. One, 2- and 3-year overall survival rates were 42.85% (9/21), 28.57% (6/21), and 14.29% (3/21), respectively, with a median overall survival rate of 16.5 months. Eight patients developed duodenal ulcer as a late complication of radiotherapy, and 4 patients died of gastrointestinal bleeding. Conclusions 3D-CRT can be considered as a valuable palliative approach for unresectabe hilar cholangiocarcinoma, and effective management of the late complications of radiotherapy play a key role in increasing survival rates of the patients.
