本文对原发生性卵巢上皮癌(卵巢癌)发病的高危险因素进行配对研究。共选用卵巢癌病例62例,对照124例。详细了解病例和对照的月经史、生育史、嗜好和某些病毒感染情况等。发现月经不规则、不育和孕次较少以及流行性腮腺炎 (流腮)感染均与卵巢癌发病有关。怀孕次数越少患卵巢癌的相对危险度(RR)越大。似乎随怀孕次数的增加,卵巢癌患者相对比减小,对照组相对比却有增大的趋势。经ZxC表线性回归检验,差别显著。提出妊娠可能是卵巢癌的保护因素之
In this paper, the high incidence of primary epithelial ovarian cancer (ovarian cancer) risk factors for paired study. A total of 62 cases of ovarian cancer selection, control 124 cases. Learn more about the history of menstruation, birth history, hobbies and certain viral infections in both cases and controls. Found irregular menstruation, infertility and pregnancy less and mumps (gruel) infection are associated with the incidence of ovarian cancer. The fewer the number of pregnancies, the greater the relative risk of ovarian cancer (RR). It seems that with the increase in the number of pregnancies, ovarian cancer patients is relatively reduced compared with the control group but there is an increasing trend. The ZxC table linear regression test, the difference was significant. Proposed pregnancy may be a protective factor in ovarian cancer
