Multi-modality treatment in males with advanced malignant germ cell tumours. II. Experience with surgery and radiotherapy following cis-platinum-based chemotherapy

After chemotherapy with cis-platinum, vinblastine and bleomycin, 33 surgical procedures were performed in 29 patients with advanced malignant germ-cell tumours. The tumour masses could be completely resected macroscopically in 26 patients. Histology of the operation specimens showed fibrosis/necrosis (9 specimens), mature teratome (13 specimens) and vital malignant tumour (11 specimens). Patients with fibrosis/necrosis or completely resected mature teratoma had an excellent prognosis, whereas only 5 of the 11 patients with vital malignant tumour survived in spite of second-line treatment with chemotherapy/radiotherapy. Preoperatively elevated serum levels of AFP, beta-HCG and/or LDH indicated the presence of residual vital malignant germ cell tumour. Eight of 14 patients were rendered tumour-free by radiotherapy given as second- or third-line treatment. In general, tumour masses, remaining after cis-platinum-based induction chemotherapy should be resected as completely as possible even in the case of mature teratoma or fibrosis/necrosis. Radiotherapy should be considered as second- and third-line treatment in selected patients.
