Official title

Phase IIB Pre-Surgical Trial of Oral Tamoxifen Versus Transdermal 4-hydroxytamoxifen in Women With DCIS of the Breast

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This randomized phase IIB trial studies how well tamoxifen or afimoxifene works in treating patients with estrogen receptor positive breast cancer. Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen citrate or afimoxifene may fight breast cancer by blocking the use of estrogen by the tumor cells.
