Is there a role for second-look laparotomy in the management of malignant germ cell tumors of the ovary? Experience at Institut Gustave Roussy.
The last two decades have seen great improvements in the management of patients with germ-cell tumors of the ovary. The initial treatment approach includes conservative surgery and cisplatin-based chemotherapy in most cases. At completion of chemotherapy, the role of second-look surgery remains questionable. We retrospectively analyzed the long-term outcome (median follow-up, 8 years) of 40 patients who received various chemotherapy regimens after primary surgery and focused on the role of second-look surgery. A second-look laparotomy was performed at completion of chemotherapy in 22 patients. Histological findings were no tumor in 13; mature teratoma in 5; immature teratoma in 1; active disease in 3. Six of the latter nine patients had persistent radiologic abnormalities after chemotherapy. All three patients with active disease had elevated serum tumor markers. Five out of the six patients with residual teratoma lesions had a teratoma component in the primary tumor. According to histological findings at second-look surgery, the number of patients without long-term evidence of disease is 12, 5, 1 and 0, respectively. Eighteen patients were not subjected to second-look surgery. One of them had clearly progressive disease and the other 17 experienced a clinical complete response at completion of chemotherapy. All patients but one are alive without evidence of disease. We conclude that second-look surgery is not necessary in patients with elevated serum tumor marker levels and in those patients with neither radiologic abnormality nor teratoma element in the primary tumor. However, we recommend a second-look procedure for the small subset of patients with a teratoma component in the primary tumor and persistent radiologic abnormalities along with normal serum tumor markers at the end of chemotherapy.
