title: [A case of male breast cancer with special reference to the hormonal environment during chemoendocrine therapy].
abstract: Chemoendocrine therapy was performed on a man with advanced breast cancer, and partial response was observed for 11 months. Estrogen receptor in cancer tissue was detected before and after the therapy. Progesterone receptor, however, was not detected after the treatment, whether it had been there or not prior to it. The serum estrone level was continuously high during the treatment, but the serum testosterone level was obviously decreased after that.
