[Two cases of primary peritoneal cystadenocarcinoma--diagnosis, treatment, and clinical feature]

Abstract

Primary peritoneal adenocarcinoma is rare, originating in the paramesonephric duct (müllerian duct). We report two cases of primary peritoneal adenocarcinoma. Both patients received a surgical resection. The pathological diagnosis of the resected specimen was papillary adenocarcinoma with clear cell carcinoma. The response after the combination chemotherapy using CDDP and TS-1 was "PR", and these treatments were effective to improve the patients' quality of life in each case.
