(1)扼要介绍有关恶性肿瘤 ABO 血型分布之研究状况。(2)分析几种常见恶性肿瘤(胃癌、宫颈癌及乳癌)1336例之血型分布。胃癌483例的 A 型百分比显著较对照组高,与国外大多数报告相符。宫颈癌316例及乳癌537例之血型分布与对照组无显著差异。 (3)介绍各家对胃癌 A 型较多之解释,并加以讨论。强调此类研究需要大组病例,明确之病理诊断及适宜之对照组。
(1) Outline the research status of ABO blood group distribution in malignancy. (2) Analysis of blood group distribution in 1336 cases of several common malignancies (gastric cancer, cervical cancer and breast cancer). The percentage of Type A in 483 cases of gastric cancer was significantly higher than that in the control group, which is consistent with most reports in foreign countries. There was no significant difference in blood group distribution between 316 cases of cervical cancer and 537 cases of breast cancer. (3) Introduce various explanations for gastric cancer type A and discuss them. Emphasis on this type of study requires a large group of patients, a clear pathological diagnosis and a suitable control group.
