位于肝外胆道的癌肿不但小而难以诊断,且常因侵犯邻近血管以致不能切除。尽管癌肿生长缓慢,化疗或放疗等辅助措施,均无助于改善其较低的存活率。最近发现这类病灶可能有多源性及弥漫性生长,情况更为复杂。为了检出一些有价值的影响预后的因素,作者分析了1954年11月到1978年6月间96例肝外胆管癌病例,计男性59例,女性37例;95例作了手术,1例等待手术时死亡。作最后一次手术时的平均年龄为59.9岁。47例的病灶位于上(1/3)段胆道,并累及左右
The cancer located in the extrahepatic biliary tract is not only small but difficult to diagnose, and is often inaccessible due to invasion of adjacent blood vessels. Despite the slow growth of cancer, adjuvant measures such as chemotherapy or radiotherapy do not help improve its lower survival rate. It has recently been found that such lesions may have multiple sources and diffuse growth, and the situation is more complicated. In order to detect some valuable prognostic factors, the authors analyzed 96 cases of extrahepatic cholangiocarcinoma between November 1954 and June 1978, including 59 males and 37 females; 95 patients underwent surgery and 1 patient. Waiting for surgery to die. The average age at the time of the last operation was 59.9 years. 47 lesions were located in the upper (1/3) biliary tract, and involved left and right
