Summary
Brief summary (as posted)
Several factors discourage the implementation of cancer screening to the population in general, which would result in earlier diagnosis and an expected improved survival. Concurrent in vivo and in vitro research has shown that drug acetylation activity is increased in cancer. Amantadine may be of value in detecting the presence of cancer. Accordingly, this study will examine how Amantadine is eliminated by the body in cancer patients. This is an important step in validating a cancer detection method that can be implemented economically for screening of large numbers of people.
