Drug-induced subacute cutaneous lupus erythematosus (DI-SCLE) has been associated with numerous drugs, but there are limited reports of its association with aromatase inhibitor anastrozole. We report the case of a patient undergoing treatment with anastrozole for breast cancer who presented with clinical, serological, and histological evidence consistent with DI-SCLE. Her condition quickly bega...
The development of resistance to the antiestrogen tamoxifen occurs in a high percentage of initially responsive patients. We have developed a new model in which to investigate acquired resistance to triphenylethylenes. A stepwise in vitro selection of the hormone-independent human breast cancer variant MCF-7/LCC1 against 4-hydroxytamoxifen produced a stable resistant population designated MCF7/...
TAS-108 is a novel steroidal antiestrogen compound that has a strong binding affinity to the estrogen receptor and, in preclinical studies, has antitumor activity against tamoxifen-resistant breast cancer cell lines. Its molecular mechanisms of actions are different from those of tamoxifen and fulvestrant. TAS-108 showed tissue-selective agonist activity in the bone and cardiovascular systems a...
PURPOSE Cross-resistance is an important issue for the evaluation of new antiestrogens to treat advanced breast cancer patients who have failed tamoxifen therapy. In addition, postmenopausal patients treated with long-term adjuvant tamoxifen show a 3-4-fold increase in the risk of developing endometrial cancer. Consequently, a new second line agent should be more antiestrogenic and less estroge...
PURPOSE Phosphatidylinositol 3-kinase (PI3K) inhibitors are being developed for the treatment of estrogen receptor α (ER)-positive breast cancer in combination with antiestrogens. Understanding the temporal response and pharmacodynamic effects of PI3K inhibition in ER(+) breast cancer will provide a rationale for treatment scheduling to maximize therapeutic index. EXPERIMENTAL DESIGN Antiestr...
