乙型肝炎与原发性肝细胞癌(简称肝癌)之间的病因关系是举世瞩目的问题,探讨两病的分布特点,有助于对病因关系的认识,如乙型肝炎与肝癌间存在因果关系,则两病在人群中的分布趋势应该一致。1963年苏氏首次提出钉螺的分布符合负二项分布,1980年苏氏又指出肝癌病例的发生符合泊阿松(Poisson)分布,与乙型肝炎分布不同,观察肝癌高发地区,未见乙型肝炎作为肝癌病因的证据。有关乙型肝炎的分布特
The etiological relationship between hepatitis B and primary hepatocellular carcinoma (referred to as liver cancer) is the world’s attention, to explore the distribution of the two diseases, contribute to the understanding of the cause of the relationship, such as the existence of causation between hepatitis B and liver cancer Relationship, then the distribution of the two diseases in the population trend should be the same. In 1963, for the first time, the Soviet Union proposed the distribution of snails conforming to the negative binomial distribution. In 1980, Su pointed out that the occurrence of hepatocellular carcinoma was consistent with the Poisson distribution. In contrast with the distribution of hepatitis B, Hepatitis as evidence of the cause of liver cancer. The distribution of hepatitis B special
