Distant metastases in epithelial ovarian carcinoma

Abstract

A review of 255 patients with epithelial ovarian carcinoma revealed that metastases consistent with Stage IV disease developed in 97 patients (38.0%) at some time during the natural history of their disease. Malignant pleural effusions developed in 63 patients (24.7%), and their median survival (from the time of diagnosis of the effusion) was 6 months. Parenchymal liver metastases developed in 24 patients (9.4%; median survival, 5 months); parenchymal lung metastases in 18 patients (7.1%; median survival, 8 months); distant lymph node metastases in 18 patients (7.1%; median survival, 9 months); subcutaneous nodules in nine patients (3.5%; median survival, 12 months); a malignant pericardial effusion in six patients (2.4%; median survival, 2.3 months); central nervous system metastases in five patients (2%; median survival, 1.3 months); and bone metastases in four patients (1.6%; median survival, 4 months). Patients with Stage IV disease at the time of diagnosis had a median survival of 9.1 months, while patients with a delayed occurrence of distant metastases had a median survival of only 4 months from the time of diagnosis of the distant metastases. Significant risk factors for distant metastases were malignant ascites, peritoneal carcinomatosis, large metastatic disease within the abdomen, and retroperitoneal lymph node involvement at the time of the initial surgery. The significance of positive retroperitoneal nodes and bulky upper abdominal disease has important therapeutic implications.
