[High dose chemotherapy with peripheral blood stem cell transplantation (PBSCT) For advanced testicular cancer].
Five patients with metastatic testicular cancer of advanced extent according to the Indiana University criteria were enrolled into this study. All tumors were non-pretreated non-seminomas. Initially all patients were treated with standard dose etoposide, ifosfamide and cisplatin (VIP) regimen. The response of two cycles of VIP was evaluated by tumor markers and diagnostic imagings. Two of the five patients showed a good response to VIP and subsequently achieved a pathological complete response (pCR) following surgical resection of residual masses after 3 or 5 courses of VIP. However, they suffered from severe myelosuppression and underwent peripheral blood stem cell transplantation (PBSCT) following the final course of VIP. The remaining three patients unlikely to be cured by VIP underwent chemotherapy consisting of high dose ICE:ifosfamide (6-10 g/m2 over 4days) carboplatin (1,500 mg/m2 over 4 days), etoposide (1,600-2,400 mg/m2 over 4 days) combined with PBSCT. This regimen resulted in one partial response (PR) with marker-negative and two PR with marker-positive. Residual masses were removed in all three patients and viable tumor cells were found in two. Of the five patients enrolled, four patients (80%) remain disease-free with minimal follow-up of 20 months, and the remaining one died of cancer 10 months after PBSCT. No serious side effects or complications were encountered. This study shows that standard dose induction therapy of VIP followed by early salvage chemotherapy of high dose ICE with PBSCT is well tolerated and effective in the treatment of advanced poor-risk testicular cancer.
