血型是人类遗传的标记之一。50年代,Aird等发现A血型的人与胃癌发病有伴行关系,导致出现大规模研究ABO血型与疾病关系的热潮。结果,仅有少数疾病与ABO血型有微弱的关系。笔者对肝胆癌作统计时发现,其中B血型出现的频率较正常ABO血型频率高,为了进一步证明消化系统癌症与血型是否有伴行关系,我们对沈阳和本溪地区五家医院共 Blood type is one of the markers of human genetics. In the 1950s, Aird et al. found that people with A blood types were associated with the onset of gastric cancer, leading to a large-scale study of the relationship between ABO blood type and disease. As a result, only a few diseases have a weak relationship with the ABO blood group. The author’s statistics on hepatobiliary cancer found that the frequency of B blood group was higher than the frequency of normal ABO blood group. To further prove whether the cancer of the digestive system is associated with blood type, we have a total of five hospitals in Shenyang and Benxi.
