Abstract
Two hundred seventy-nine patients with previusly untreated nonresectable adenocarcinoma of the lung (ACL) entered a prospective randomized trial, comparing vindesine (VDS) to a combination of lomustine (CCNU), cyclophosphamide (CTX), and methotrexate (MTX), and to a regimen including all four drugs. Response assessment was possible in 218 patients, while 259 were evaluable for survival. Response rates were similar (22%, 23%, and 27%, respectively) as were median durations of response (15 weeks overall) and survival (29 weeks overall). Patients with dose-limiting toxicity had significantly higher response rate and longer survival than patients without toxicity. The major toxicity was peripheral neuropathy with VDS treatment and myelosuppression with the other two regimens. The VDS single-agent activity in ACL was confirmed, but addition of VDS to the three-drug regimen did not increase activity. Future studies of VDS in combination with other active agents, and comparison to a matched control group on supportive care, are indicated.
