The present study evaluated the feasibility and effectiveness of myeloablative high-dose chemotherapy and autologous stem cell transplantation in patients with relapsed or progressed central nervous system germ cell tumors (CNS-GCTs). Eleven patients with non-germinomatous germ cell tumors and nine patients with germinomas were enrolled. Patients received between two and eight cycles of conventional chemotherapy prior to HDCT/autoSCT with or without radiotherapy. Overall, 16 patients proceeded to the first HDCT/autoSCT, and nine proceeded to the second HDCT/autoSCT. CTE (carboplatin-thiotepa-etoposide) and cyclophosphamide-melphalan (CM) regimens were used for the first and second HDCT, respectively. Toxicities during HDCT/autoSCT were acceptable, and there were no treatment-related deaths. Twelve patients experienced relapse or progression; however, four patients with germinomas remain alive after subsequent RT. Therefore, a total of 12 patients (four NGGCTs and eight germinomas) remain alive with a median follow-up of 47 months (range 22-90) after relapse or progression. The probability of 3-year overall survival was 59.1 +/- A 11.2 % (36.4 +/- A 14.5 % for NGGCTs vs. 88.9 +/- A 10.5 % for germinomas, P = 0.028). RT, particularly craniospinal RT, was associated with a better tumor response prior to HDCT/autoSCT and a better final outcome. In conclusion, HDCT/autoSCT was feasible, and survival rates were encouraging. Further study with a larger cohort of patients is needed to elucidate the role of HDCT/autoSCT in the treatment of relapsed or progressed CNS-GCTs.
