复发晚期直肠癌的放射治疗(附22例分析)

Palliative Radiotherapy of Recurrent Advanced Rectal Cancer (Clinical Analysis of 22 Cases)

报告深圳币人民医院肿瘤科1987年1月至1995年12月对22例晚期复发的直肠放疗的结果。本组病人年龄30～81岁。男11例，女11例。放疗结束时病人会阴区疼痛症状完全及部分缓解达100％，肿块缩小者达63％。经随访，无症状生存达3个月者15例，达半年者6例。全组病人平均生存13月。作者认为，对于晚期复发直肠癌，放射治疗能起姑息减症的作用，但剂量不宜过高，一般在40～65Gy．为宜。膀胱刺激症状及会阴皮肤破溃为放疗主要并发症。放疗配合微波热疗能否提高疗效尚待观察。

The median survival pened was 13months.The authors believe that radiotherapy is very effective in improving the quality of life for the patients with recurrent rectal carcinoma ,but the local dose should not be above 70Gy. The real value of hypertherrnia combined with radiotherapy for recurrent advanced rectal cancer awaits further study.
