Abstract

To investigate risk factors for breast cancer in Taiwan, a low-incidence area, a case-control study was conducted. This comprised 244 subjects with diagnosed and pathologically confirmed breast cancer (age range 20-80 years) and 450 female ophthalmology outpatients as controls. Univariate and multiple logistic regression analysis suggests that breast cancer in Taiwan is aetiologically similar to breast cancer in high to moderate-incidence areas. A family history of breast cancer appears to be the most important factor contributing to the risk of breast cancer (odds ratio = 4.69). The effect of reproductive hormones (represented by the years of history of menses in premenopausal women, odds ratio = 3.35; or the age at menarche in post-menopausal women, odds ratio = 2.67) plays a significant role in tumorigenesis. Breast feeding appears to be a particularly important protective factor in Taiwanese women (odds ratio = 0.57).

摘要

为了调查低发病率地区台湾乳腺癌的风险因素,开展了一项病例对照研究。该研究包括244例经诊断和病理确诊的乳腺癌患者(年龄范围20 - 80岁)以及450名女性眼科门诊患者作为对照。单因素和多因素逻辑回归分析表明,台湾的乳腺癌在病因上与高至中等发病率地区的乳腺癌相似。乳腺癌家族史似乎是导致乳腺癌风险的最重要因素(优势比 = 4.69)。生殖激素的影响(以绝经前女性的月经史年限表示,优势比 = 3.35;或以绝经后女性的初潮年龄表示,优势比 = 2.67)在肿瘤发生中起重要作用。母乳喂养似乎是台湾女性特别重要的保护因素(优势比 = 0.57)。
