PURPOSE: A phase II trial was undertaken to assess the feasibility,
toxicity, and efficacy of high-dose carboplatin and etoposide with
autologous bone marrow transplantation in patients with relapsed or
refractory germ cell tumors. PATIENTS AND METHODS: Forty patients with
recurrent germ cell cancer received carboplatin 500 mg/m2 and etoposide 400
mg/m2 given at 7, 5, and 3 days before marrow infusion. Autologous marrow
infusion (day 0) was accomplished using one half of the bone marrow
harvested before chemotherapy. Patients who achieved a complete or partial
response with the first cycle of treatment received a second identical
cycle of chemotherapy followed by infusion of the remaining cryopreserved
bone marrow. RESULTS: Objective responses were obtained in 17 of the 38
patients (45%) assessable for response, including eight partial and nine
complete remissions. Five of these patients remain in continuous complete
remission with minimal follow-up of 1 year. Toxicity encountered was
primarily hematologic, and five patients (13%) died of treatment-related
complications. Significant toxicities often seen with high-dose cisplatin
(ototoxicity, neurotoxicity, and renal toxicity) were manageable in this
regimen of high-dose carboplatin. CONCLUSIONS: This trial confirms the
curative potential of high-dose carboplatin and etoposide in highly
refractory germ cell cancer.
