VAB-6 as initial treatment of patients with advanced seminoma.

Thirty patients with advanced seminoma were treated with VAB-6. Eighteen patients were previously untreated, eight had relapsed after radiation therapy, and four had persistent disease following chemotherapy and radiation therapy. Two patients had received prior high-dose cisplatin. Twenty-four (86%) of 28 evaluable patients achieved a complete remission. Four patients had relapsed. The median disease-free follow-up of patients achieving complete remission was 32+ months. VAB-6 is effective treatment for patients with advanced seminoma, and chemotherapy is recommended as the initial therapy in all patients with stage II seminoma with disease larger than 5 cm, extragonadal seminoma, and stage III seminoma.
