| Abstract: |
| 对天津市1977~1980年间的516例乳腺癌病例与健康人作了配对调查。结果表明,影响乳腺癌的发病因素与平均月收入高、受教育水平高、某些技术性和文化程度要求高的职业、月经初潮年龄早、结婚和生育年龄晚。胎次少以及乳腺癌及其它癌家族史有明显关系。其中大多数因素对乳腺癌的危险性增高,只有较弱的作用(RR在1.5~2.0~3.0之间),但其联合作用可能大大增加其促癌作用,如受过大学教育的人RR大为升高(8.04)可能说明这种情况。乳腺癌家族史对患本病的危险性很大(RR10.0),虽如此,但它在整个人群中的作用不大,本调查中只有4%的乳腺癌妇女有此家族史。 |

| Pairing investigations were carried out between 516 cases of mastocarcinoma and normal persons in Tianjin from 1977 to 1980. Results showed that there was an evident corelation between the pathogenetic factors influencing the incidence of mastocarcinoma and the following conditions, i. e. higher average income per mensem; higher educational levelj certain professions requiring special technical and high cultural leveli precocious menstruation; marriage and childbearing at a rather late agej the number of pregnancy few and the familial history of mastocarcinoma or other cancers. Among those factors mentioned above, certain ones of the majority exerted only rather weak effect on the increase of risks of mastocarcinoma (RR between 1.5~2.0 or 3.0); However, their combined effects might greatly increase the potential risk of carcinogenesis. For example, the RR of individuals educated at college level increased greatly (8.04). The familial history of mastocarcinoma was found to play a role in the risk of certain indiuidual (RR 10.0)。Nevertheless, it exerted little influence on the whole population. The present study revealed that only 4% of those women suffering from mastocarcinoma had had familial history. |
