BACKGROUND: The authors conducted a pilot, randomized, open label with blind assessment, controlled trial to determine whether vitamin E supplementation has a neuroprotective effect in chemotherapy-induced peripheral nerve damage. METHODS:Thirty-one patients with cancer treated with six courses ofcumulative cisplatin, paclitaxel, or their combination regimens were randomly assigned in two groups and followed by neurologic examination and electrophysiologic study. Patients assigned in Group I (n = 16) received oral vitamin E at a daily dose of 600 mg/day during chemotherapy and 3 months after its cessation were compared to patients of Group II (n = 15), who received no supplementation and served as controls. The severity of neurotoxicity was summarized by means of a modified peripheral neuropathy score. RESULTS: The incidence of neurotoxicity differed between the two groups, occurring in 4/16 (25%) patients assigned in the vitamin E supplementation group and in 11/15 (73.3%) patients assigned in the control group (p = 0.019). Mean peripheral neuropathy scores were 3.4 +/- 6.3 for patients of Group I and 11.5 +/- 10.6 for patients of Group II (p = 0.026). The relative risk (RR) of developing neurotoxicity was significantly higher in case of control patients, RR = 0.34, 95% CI = 0.14 to 0.84. CONCLUSION:Vitamin E supplementation in cancer patients may have an important neuroprotective effect.
