Is there a role for vindesine in the treatment of non-small cell lung cancer?

Vindesine is a semisynthetic derivative of vinblastine which has been evaluated in clinical studies since the late 1970's. The literature on vindesine in the treatment of non-small cell lung cancer has been reviewed and all aspects of vindesine treatment in this disease has been covered. It is concluded that vindesine as a single agent yields a response rate of 18% based on the treatment of 295 patients included in phase II trials (95% confidence limits 13%-22%). No difference was observed among the three major histologic types of non-small cell lung cancer. In phase III trials, the response rate and confidence limits are at a similar level. Combination chemotherapy including vindesine plus cisplatin ranks among the most active treatments in non-small cell lung cancer and is as active as etoposide plus cisplatin, both with respect to response rate and survival. It has not been documented that the addition of one or two other drugs to the combination of vindesine yields an increase in survival. When best supportive care was compared with a combination of vindesine plus cisplatin, the group with chemotherapy was attributed a survival advantage in all three studies published, and the difference was statistically significant in two of these three studies. Thus, vindesine has a well documented activity in non-small cell lung cancer and ranks among the most active single agents in this disease. Vindesine is also part of several active combination chemotherapies among which the combination of vindesine plus cisplatin is particularly interesting, because it has been repeatedly shown to prolong survival as compared to supportive care. Especially this latter point leads to the conclusion that there is a role for vindesine in the treatment of non-small cell lung cancer. However, the concept of chemotherapy in this disease remains investigational even though the advances seen in recent years clearly merit further studies.
