Remission with carboplatin of paclitaxel resistant primary peritoneal papillary serous carcinoma: case report

Primary peritoneal papillary serous adenocarcinoma is histologically identical to ovarian papillary serous adenocarcinoma. This diagnosis is made if the ovaries are of normal size with either no tumor or only minimal surface involvement. We describe a patient with a primary peritoneal papillary serous adenocarcinoma which was resistant to initial therapy with paclitaxel, but subsequently achieved a partial response with carboplatin-based chemotherapy. Accordingly, carboplatin therapy should be considered in paclitaxel resistant primary peritoneal papillary serous carcinoma.
