Incidence data reported for biliary tract cancer in 4 ethnic groups of Los Angeles County are consistent with earlier reports of a similarity between the ethnic-gender distribution of gallbladder cancer and bile lithogenicity, and between that of other biliary cancer and free bilirubin. The female excess of biliary cancer proved to be highest in those ethnic groups with highest average parity, and risk was related to parity correlates such as marital status and religion (Catholic). A migration effect in Spanish-surnamed and other white females was present for both diseases.
洛杉矶县4个种族群体中报道的胆道癌发病率数据与早期报告一致，即胆囊癌的种族-性别分布与胆汁致石性之间存在相似性，其他胆管癌与游离胆红素之间也存在相似性。结果表明，在平均生育胎次最高的种族群体中，女性胆道癌发病率过高的情况最为明显，且风险与生育相关因素如婚姻状况和宗教信仰（天主教）有关。西班牙裔和其他白人女性在这两种疾病中均存在迁移效应。
