Randomized phase III trial of vinblastine, bleomycin, and cis- dichlorodiammine-platinum versus dacarbazine in malignant melanoma
SD Luikart, GT Kennealey and JM Kirkwood
A randomized phase III study was carried out in 57 patients with metastatic
melanoma treated with either dacarbazine (DTIC) given intravenously (IV)
daily for 10 days using light protection, or a combination of vinblastine
IV on days 1 and 2, bleomycin by continuous IV infusion during days 1-5,
and cisplatin by IV infusion on day 5 (VBD). Objective response rates were
similar: 14% for dacarbazine and 10% for VBD. However, dacarbazine
responses were associated with a trend toward longer progression-free
intervals and longer survival. Toxicity was significantly greater in the
VBD arm, and fatal in two patients. Dacarbazine was also associated with
severe toxicity by the 10-day light-protected schedule used here. VBD is
not as effective as previously reported, and dacarbazine remains a standard
of therapy for metastatic melanoma.
