title: Feasibility study of high-dose carboplatin and etoposide in the salvage treatment of testicular cancer.
abstract: Eleven patients with testicular cancer, either relapsing after or refractory to cisplatin-based chemotherapy, underwent salvage chemotherapy with high-dose carboplatin (800 mg/m2 on day 1) and high-dose etoposide (500 mg/m2 on days 1, 3 and 5). A total of 21 courses were administered. The major toxicity consisted of profound myelosuppression. There were two toxic deaths, both caused by infection during neutropenia. Bone marrow recovery was usually complete around day 26 (range 19-129). Other toxicities included mild mucositis, nausea and vomiting, and alopecia. No significant neurotoxicity or hearing loss were observed and only one patient had a moderate decrease in renal function. Nine of ten evaluable patients responded, with one complete remission, 6 partial remissions with normalization of tumor markers, and two partial remissions with over one log decrease of tumor markers. The duration of these remissions was not evaluable, since only three evaluable and responding patients did not receive additional therapy after HD-CE. All three relapsed after discontinuing chemotherapy. HD-CE has activity in relapsing or refractory testicular cancer and can be administered without bone marrow support. The regimen may thus be suitable to be used as a remission induction regimen prior to consolidation with intensive chemotherapy and autologous bone marrow transplantation.
