A case-control study of 143 Japanese women with uterine endometrial cancer and 143 individually age-matched controls was conducted to assess the risk factors for endometrial cancers in Japan. Among the characteristics studied, the following factors were significantly greater in the cases than in the controls: nulliparity (odds ratio for parity 1-3 and > or = 4 versus nullipara are 0.40 and 0.02, respectively), obesity (odds ratio: 2.73), hypertension (odds ratio: 2.4), diabetes mellitus (odds ratio: 6.30), and a personal medical history of cancer (odds ratio: 3.06). The present study showed that Japanese women have the same risk factors for endometrial cancer as those reported in Western countries. The recent increase in the incidence of endometrial cancer in Japan may be largely attributed to the decrease in parity.
一项针对143名日本子宫内膜癌女性患者和143名年龄匹配的个体对照进行的病例对照研究,旨在评估日本子宫内膜癌的危险因素。在所研究的特征中,以下因素在病例组中显著高于对照组:未生育(生育1 - 3次和≥4次与未生育的比值比分别为0.40和0.02)、肥胖(比值比:2.73)、高血压(比值比:2.4)、糖尿病(比值比:6.30)以及个人癌症病史(比值比:3.06)。本研究表明,日本女性患子宫内膜癌的危险因素与西方国家报道的相同。日本近期子宫内膜癌发病率的上升可能在很大程度上归因于生育次数的减少。
