Abstract

Between 1970 and 1990, 160 patients with malignant non-dysgerminomatous ovarian germ cell tumors have been treated at our own institution. Primary therapy failed in 42 of these patients, who constitute the basis for this study. Seventeen patients had stage I disease, 5 stage II, 17 stage III, and 3 stage IV. Histologic type included 13 immature teratomas, 8 endodermal sinus tumors, and 21 mixed germ cell tumors. Primary therapy for 14 patients was surgery alone, for 23, surgery plus chemotherapy, for 2, surgery plus radiotherapy and for 3, all three modalities. Median progression-free survival from initial diagnosis lasted 6.8 months (range, 0.9–24 months). Thirty-four patients received chemotherapy as part of salvage; 5/11 (45%) who received VAC are disease-free, and 6/11 (55%) who received cisplatin combinations are disease-free. When primary VAC failed, 3/7 (43%) were salvaged with cisplatin combinations. When primary cisplatin combinations failed, 2/5 (40%) were salvaged. Twelve of the 42 patients (29%) are currently alive disease-free. Primary treatment failure was attributed to surgery alone for 14 patients (7 because of misdiagnosis), radiotherapy for 5, and toxicity for 1. Of the 22 patients who failed chemotherapy, 12 did so because of a suboptimal regimen, 3 because of possible dose-intensity problems, one because of non-compliance, and 6 for unexplained reasons. Patients with ovarian germ cell tumors have an excellent probability of cure with aggressive primary therapy, but successful salvage may be difficult when primary treatment fails.
