Vinorelbine: a new promising drug in Hodgkin's disease.

Vinorelbine is a new semisynthetic vinca alkaloid that differs chemically from vinblastine by a substitution of the catharanthine moiety. The powerful cytostatic activity of vinorelbine against murine tumors, human malignant cell lines and human tumor xenografts in nude mice has been demonstrated. Phase I-II studies of intravenous vinorelbine, administered weekly as single agent or in combination chemotherapy have been conducted since 1986. Results suggest that vinorelbine has high activity in non-small cell lung cancer, breast cancer and cisplatin-resistant ovarian cancer with mild toxicity, being neutropenia the major treatment related complication. In this paper we critically review the activity of vinorelbine in pretreated Hodgkin's patients. Available results strongly suggest the inclusion of this drug in first or second line chemotherapy regimens in Hodgkin's disease.
