雌激素受体表达与癌家族史阳性乳腺癌的关系

目的　为了探讨癌家族史阳性乳腺癌妇女ER水平是否高于非癌家族性乳腺癌者。方法　采用莹光组织化学法检测了本院 1985～ 1998年间 430例妇女可手术乳腺癌的新鲜组织ER水平 ,对其中癌家族史阳性乳腺癌ER与非癌家族性乳腺癌ER水平进行比较分析。结果　在 430例乳腺癌组织总的ER阳性率为 5 0 .2 % (2 16 / 430 ) ,其中绝经期前、后ER阳性率分别为 46 .3 % (6 8/ 14 7)和 5 0 .7% (10 7/ 2 11)。癌家族史阳性乳腺癌ER阳性率为 5 5 .1% (2 7/ 49) ;家族性乳腺癌ER阳性率为 72 .2 % (8/ 11) ;非癌家族性乳腺癌ER阳性率为 49.6 % (189/ 381)。结论　癌家族史阳性乳腺癌ER和家族性乳腺癌ER水平分别与非癌家族性乳腺癌ER相比 ,各呈明显增高倾向 ,但经统计学处理P >0 .0 5 ,认为无显著差异。本组乳腺癌病人中至少半数病例属于雌激素受体依赖性肿瘤 ,而且绝经期后水平略高于绝经期前者。

Relationship between expression of estrogen receptor and breast cancer with a positive cancerous family history

Objective To explore whether ER level of breast cancer with a positive cancerous family history shows a higher level than the breast cancer of non cancerous family.Methods ER were determined in 430 fresh specimen of breast cancer by fluorescent estradiol histochemical technique.Results Total ER positive rate was 50.2%,ER positive rate was 55.1% in the breast cancer with a positive cancerous family history.ER positive rate was 72.2% in women with a family history of breast cancer and ER positive rate was 49.6% in non cancerous family women.Conclusions ER level in breast cancer with a positive cancerous history and family history of breast cancer is significant higher than that in the breast cancer of non cancerous family without statistical difference(P>0.05).
