据报告胆囊癌在胆道手术中约占1～2％,其临床特征为发现晚、治疗无显效和预后差。自1977年以来,作者对20例胆囊癌作术后放疗,平均总量为4200rad。作者认为,术后放疗似可使姑息性切除或末切除的患者存活时间延长。但有关胆囊癌术后放疗仅有少数散在的报告,没有一组超过10例,且大多数为胆管癌合併胆囊癌。本文旨在对20例胆囊癌术后放疗问题作一评价。 [临床资料] 本组20例中,男7例,女13例、年龄50～74 Gallbladder cancer is reported to account for approximately 1-2% of biliary tract surgeries. Its clinical features are late detection, poor treatment, and poor prognosis. Since 1977, the authors performed postoperative radiotherapy for 20 cases of gallbladder cancer, with an average total of 4200 rad. The authors believe that postoperative radiotherapy appears to prolong the survival of patients undergoing palliative resection or resection. However, only a few scattered reports of postoperative radiotherapy for gallbladder cancer have been reported. No group has more than 10 cases, and most of them are cholangiocarcinoma and gallbladder cancer. This article aims to evaluate 20 cases of postoperative radiotherapy of gallbladder cancer. [clinical data] 20 patients in this group, 7 males and 13 females, aged 50-74
