title: Secondary surgery in patients with malignant germ cell tumors.
abstract: A total of 102 men treated for germ cell tumor with chemotherapy containing cisplatin was referred for a secondary operation with signs of tumor in the retroperitoneum or chest. Of the patients 85 underwent laparotomy, 14 underwent thoracotomy and 3 had both operations. Residual tumors were completely resected in 66 patients and incompletely resected in 30, while no tumor was found in 6. The resected specimen was malignant in 18 patients, of whom 11 had complete removal of all malignant tissue. All patients with malignancy in the resected specimen received further chemotherapy. Long-term disease-free status was obtained in 75% of those patients who had a complete resection, compared with 14% in the group with incomplete resection. There was no evidence of malignant disease at operation in 78 patients but 5 of them later died of the disease. Malignant tissue was present in the residual tumor in only 1 of 15 patients whose primary tumor was seminoma alone. Resection was attempted in 14 patients despite abnormal tumor markers preoperatively. Only 5 of these patients achieved a disease-free status and 2 of them died later of malignant disease. Over-all 79 of the 102 patients are without evidence of disease (medium postoperative observation 23 1/2 months). We conclude that a secondary operation constitutes an important part of the treatment of patients with germ cell cancer.
