Early intensified chemotherapy with autologous bone marrow transplantation in first line treatment of poor risk non-seminomatous germ cell tumours. Preliminary results of a French randomized trial.
For 30 months we have treated 115 non-pretreated non-seminomatous germ cell tumour (NSGCT) patients with poor risk characteristics. Patients were allocated randomly to either arm A: NCI regimen with vinblastine, etoposide (E), bleomycin and double dose cisplatin (P2) (PVeBV) 3 or 4 cycles Q3W, or arm B: modified PVeBV protocol (bleomycin in continuous infusion) Q4W than a cycle of high-dose E + cyclophosphamide + P2 (PEC) and autologous bone marrow transplantation (ABMT). 114 patients are evaluable: 81 testicular, 18 mediastinal and 15 retroperitoneal primaries. Results: Arm A 57 patients: 7 patients did not complete the treatment. There were 15 failures, 9 PR, 33 CR. Seven patients relapsed. The 2-year survival is 82%. Arm B 57 patients: 16 patients did not complete the treatment. There were 26 failures, 7 PR and 24 CR. Nine patients relapsed. The 2-year survival is 60%. Both CR rates and survival are not statistically different. This trial fails to show any benefit of early intensified chemotherapy + ABMT to increase the CR and survival rates in poor risk NSGCT.
