Sequential intermediate high-dose therapy with etoposide, ifosfamide and cisplatin for patients with germ cell tumors.
Intermediate high dose VIP (etoposide, ifosfamide, cisplatin) achieved comparable efficacy and improved tolerance in comparison with high-dose chemotherapy plus PBSC in poor risk germ cell tumors. The aim of this study was to confirm the effectivity and tolerance of this regimen in clinical practice. Twenty-five consecutive patients, 9 previously untreated with poor prognosis and 16 relapsed, were treated with 1.6 VIP or 1.9 VIP+PBSC. A relative dose intensity of 1.6 VIP was used in 14 patients and 11 patients received the intensity of 1.9 VIP. Clinical response was achieved in 56% of patients. Fifty-eight percent of patients have survived more than 1 year and 44% more than 2 years. No significant difference was noted between previously treated and untreated patients, as well as between the patients on 1.6 VIP and 1.9 VIP, with the exception of improved 1-year survival of patients on 1.9 VIP. One of four cisplatin-refractory patients achieved durable partial remission with a normal level of tumor markers. Serious non-hematological toxicity was rare. Myelotoxicity of 1.9 VIP was less serious in comparison with 1.6 VIP regimen, but the difference was not significant. Sequential intermediate high-dose therapy is an effective and tolerable regimen for patients with poor risk germ cell tumor as well as for relapsed patients.
