Navelbine is a chemotherapy drug given to treat some breast cancers and non-small cell lung cancers. The drug comes in both oral and intravenous form. Vinorelbine interferes with the growth of cancer cells and slows their growth and spread in the body. Navelbine injection, used alone or in combination with cisplatin, is slightly more effective than other treatments. Studies have also shown that Navelbine produces less toxins than other chemotherapies and therefore has less side effects.

Mesothelioma is difficult to treat and resistant to treatment. Most chemotherapy treatments have a response rate of less than twenty percent. In a Navelbine study of 29 patients, 16 gained significant relief from the drug. The median survival rate for patients in the study was 11 months, and over forty percent were still alive a year later.

Since the growth of normal cells also may be affected by Navelbine, other effects will occur such as, reduction of production of blood cells, constipation, diarrhea, numbness or tingling in hands and feet, fatigue and pain in vein used to inject Navelbine.
