Research Abstract

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.
