I have recently been put on a chemo regimen of gemcitibine + cisplatin, and have been doing a lot of research about cisplatin side effects. The above poster is correct; there have been recent studies involving vitamin E and cisplatin, and vitamin E will help reduce peripheral neuropathy without interfering with the effectiveness of cisplatin. Also, cisplatin is notorious for "delayed" neuropathy; some people have no side effects until their treatment stops, but then develop neuropathy afterward. The neuropathy is supposed to be reversible, meaning that it eventually goes away once treatment is stopped. Do a "google" search on cisplatin and vitamin E, and you should be able to find plenty of articles addressing this issue. Good luck to you!
