Epithelial ovarian neoplasms of low malignant potential.

This report presents 13 patients with epithelial ovarian neoplasms of low malignant potential. Ten patients had serous tumors, 1 had a mucinous tumor, and 2 had endometrioid tumors. Two had Stage I disease, 4 had Stage II disease, and 7 had Stage III disease. All were treated with melphalan. Second-look laparotomy was performed in 11 patients and 1 patient required subsequent exploratory laparotomy. None achieved histologic confirmation of cure. Five patients continued treatment with melphalan and underwent third-look laparotomy with findings of persistent disease. Seven patients are alive without clinically detectable evidence of disease. Four patients died of their disease and 2 patients died of melphalan-induced acute leukemia.
