Abstract: | Of 15 patients with malignant germ cell tumours of the mediastinum, 9 patients had pure seminomas and 6 had non-seminomas. Resection was radical in only 4 non-seminomas, 1 of which was resected after chemotherapy; radiotherapy was delivered to all seminoma patients as sole therapy (2 patients) or as part of combined modality therapy. All patients with non-seminomatous tumours underwent chemotherapy (cisplatin-based combination). Therapy was generally well tolerated, but 1 seminoma patient died of sepsis. Chemotherapy achieved a 71% complete response rate in pure seminoma patients and a 33% complete response rate in non-seminoma patients. 53% of patients are alive and free of disease beyond 36 months from start of any treatment. Pure seminoma patients survived longer than non-seminoma patients (3 and 5 year survivals were 67% and 33%, respectively). Although cisplatin-based chemotherapy is highly effective in pure seminomas and also in non-seminomas, a better therapeutic approach is needed in non-seminomas. |
