本研究旨在探讨雌激素在非浸润性乳腺癌(DCIS)、浸润性癌前病变(IDC)中的作用,结果表明:(1)雌激素在DCIS和IDC中的作用不同,C-MYB、RbAp 46和Survivin在DCIS中起重要作用;芳香化酶抑制剂来曲唑治疗后,DCIS中瘤内雌激素浓度显著降低,治疗后绝大多数雌激素诱导基因的表达和细胞增殖活性均明显降低,提示DCIS患者雌激素主要由芳香化酶产生,芳香化酶抑制剂可有效抑制DCIS患者的雌激素作用。
英文摘要
We aimed to characterize the estrogen functions in noninvasive breast carcinomas (DCIS), precursor lesion of the invasive carcinomas (IDC).Results of our present study have demonstrated that (1) estrogen functions in DCIS were different from those in IDC, andC-MYB, RbAp46 and survivin played important roles in DCIS, and (2) intratumoral estrogen concentration in DCIS was markedly decreased following aromatase inhibitor letrozole treatment, and the expression of a great majority of estrogen-induced genes andproliferative activity were markedly decreased following the treatment.These results suggest that estrogen is mainly produced by aromatase in DCIS, and aromatase inhibitors may potently inhibit estrogen actions in these patients.
