title: Response of metastatic cloacogenic carcinoma to treatment with semustine.
abstract: A case of cloacogenic carcinoma of the anorectal junction with pulmonary metastases is presented. Treatment with Semustine (Methyl-CCNU) resulted in a partial response lasting 15 months. Cloacogenic carcinoma is an uncommon neoplasm against which only a few chemotherapeutic agents have been tried. Semustine should be considered in the treatment of metastatic cloacogenic carcinoma.
