Tamoxifen response following no response to orchiectomy in metastatic male breast cancer: a case report.
A male patient with advanced breast cancer had no response to orchiectomy but subsequently enjoyed a 17-month partial response to tamoxifen 10 mg B.I.D. His tumor estrogen receptor (ER) protein was 555 fmol protein/ml cytosol. The potential role of ER determinations in the selection of therapy for advanced male breast cancer is discussed.
