壶腹周围癌(vater ampulla carcinoma VPC)
这是一种比较罕见的癌症，中国并没有统计。国外的统计：
Between 1973 and 2005, 5,625 cases were recorded in the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute. Ampullary cancer now accounts for approximately 0.5% of all gastrointestinal tract malignancies.[1] The incidence has been increasing since 1973 at an annual percentage rate of 0.9%.[1]Prior to the recently reported increase, the quoted incidence for ampullary carcinoma was 0.2% of all gastrointestinal malignancies and 6% of all periampullary tumors.[4]
大意就是1973到2005这30多年间，***有5625例被NCI统计注册。目前占消化道癌症的0.5%。每年的发病率在增加，目前大约是0.9%。以前是0.2%。
