【摘要】 本文报告714例各型乳腺X线实质类型随诊2～8年(中位数4.8年)的结果,在此期间共发生乳腺癌25例,相对集中于首次摄片检查为Ⅳ_c、Ⅲ_c及Ⅱ_B的各组,其发生癌的机率分别为:14.29％、10.34％及4.17％,再次证实了该三型X线实质类型有较大的潜在发生癌的危险。另外,在随访过程中还发现低危型的Ⅲ_B及Ⅳ_B型乳腺可转化为高危型的Ⅲ_c或Ⅳ_c,从而在此基础上发生乳腺癌,此种乳腺X腺实质类型的转化常发生于>46岁的妇女,因此,在本组25例乳腺癌中,当其发生乳腺癌时,有23例发生于Ⅲ_c及Ⅳ_c型乳腺腺。更多还原

【Abstract】 Seven hundred and fourteen cases of different mammographic patterns were followed up for 2-8 years (median 4.8yrs) and 25 breast cancers were discovered during this period. The primary mammographic patterns in most of these cancer cases were type IVC, IIIC and IIB, and the probabilities of developing breast cancer in these three types were 14.29%, 10.34% and 4.17% respectively. It has been con- firmed that the type IVC, IIIC and IIB groups are the high risk groups of breast cancer. In addition, some low risk groups of breast cancer, such as type IIIB and IVB might transform to high risk groups type IIIC and IVC, especially in women over 46 years old. This may be explain that 23 of the 25 breast cancers were in the IVC and IIIC.更多还原
