The clinical outcome of high-dose chemotherapy (HDC) with autologous stem cell transplantation was retrospectively analyzed in six patients with recurrent intracranial germinoma. Prior to HDC, all patients achieved complete remission after platinum and ifosfamide-based chemotherapy. A melphalan-based conditioning regimen was administered in either a single cycle or multiple sequential cycles. Five of the six patients are alive and free from disease, with a median survival of 65 months, among which four patients avoided re-irradiation. In a significant proportion of patients, recurrent intracranial germinoma is curable by HDC without re-irradiation, provided that the disease remains sensitive to salvage chemotherapy.
