Primary papillary serous carcinoma of the peritoneum: a case of complete remission of bulky peritoneal disease after chemotherapy.

Abstract

Peritoneal papillary serous carcinoma is a rare tumor that involves the surface of the pelvic and/or abdominal peritoneum. Long-term survival among patients with this tumor has been rare. Most patients with this cancer have been treated with debulking surgery and postoperative chemotherapy. A case of incompletely resected peritoneal papillary serous carcinoma with a complete response to cisplatin-based chemotherapy is reported. Subsequent laparotomy revealed no residual tumor. This case suggests that primary chemotherapy may be successful in treating unresectable primary papillary serous tumors of the peritoneum.
