Vinblastine-ifosfamide-cisplatin treatment of bulky seminoma.
Eighteen patients with pure seminoma in advanced Stages IIC-IV of disease were treated with VIP combination chemotherapy consisting of vinblastine (6 mg/m2, days 1 and 2), ifosfamide (1.5 g/m2, days 1 to 5), and cisplatin (20 mg/m2, days 1 to 5). Eleven patients had Stage IIC, four had Stage III, three had Stage IV, and two had primary extragonadal seminoma. Primary histologic diagnoses were typical seminoma in 15 patients and anaplastic seminoma in three patients. Human chorionic gonadotropin (HCG) levels were elevated to 350 U/1 in eight patients; alpha-fetoprotein (AFP) levels were always normal. No primary lymphadenectomy was carried out. Seven of 18 patients had prior radiotherapy and were treated because of relapse or progression. There was one early death and one patient has not yet completed therapy. Of 16 evaluable patients, 14 reached complete remission (CR) (88%), which was documented surgically in six cases, whereas in the non-pretreated group, all nine patients reached CR and in the pretreated group, CR could be induced in five of seven patients (71%). The remission duration ranged from 6+ to 41+ months (median, 29+ months). No relapse has occurred. The bone marrow toxicity of VIP was remarkable. Because of leukopenia below 1000/mm3 and/or thrombopenia below 50,000/mm3, dose reduction and interval prolongation were necessary in 10 of 16 patients, especially in all those who were pretreated. Even though it is not superior to other platin-based regimens, VIP chemotherapy is highly effective in bulky seminoma with and without prior radiotherapy.
