A case of cisplatin-refractory advanced pure seminoma showing complete remission after treatment with high-dose carboplatin plus etoposide as fourth-line salvage chemotherapy

Abstract

We report the case of a patient who achieved complete remission (CR) of cisplatin-refractory metastatic pure seminoma after treatment with high-dose carboplatin and etoposide (CE) with peripheral blood stem cell transplantation as fourth-line chemotherapy. A 38-year-old man was diagnosed with advanced pure seminoma (pT3N3M1aS3). In the international germ cell consensus classification, his prognosis was classified as intermediate. He was treated with high-dose CE as fourth-line chemotherapy after treatment with BEP, VeIP, and TIN. After two cycles of high-dose CE, the concentrations of T-HCG and other tumor markers showed normal levels. A CT scan and PET–CT showed that the lymph node swelling had disappeared and there was no uptake. The CR has continued for 27 months after the treatment. High-dose CE might be less toxic and have a better prognostic outcome than other treatments as salvage chemotherapy for patients with cisplatin-refractory advanced testicular cancer.
