在美国死于胆囊癌的病人每年约有2400人。这些人开始都是隐性的,通常到外科手术时肿瘤已无法切除,从诊断的时候算起,其平均存活期少于六个月。由于这种暗淡的治疗前景,以及长期以来已认识到胆结石是引起这种危险的主要因素,因而已发现有胆结石的人都赞同预防性的胆囊切除术。事实上,近来已证实了胆囊切除率与胆囊癌死亡率之间的反比关系。 About 2,400 people die of gallbladder cancer each year in the United States. These people began to be recessive. Usually the tumors have not been removed by surgery. From the time of diagnosis, the average survival time is less than six months. Because of this dim therapeutic outlook, and the long-standing recognition that gallstones are a major contributor to this risk, it has been found that gallstones are in favor of preventive cholecystectomy. In fact, the inverse relationship between cholecystectomy and gallbladder cancer mortality has recently been demonstrated.
