Introduction: Oxaliplatin (Ox) is a frequently used platinum-based medication that is a part of many chemotherapy regimens for the treatment of several gastrointestinal malignancies. One of the most important limitations to its use is the induction of both acute and chronic peripheral neuropathy (PN). Previous studies have shown that vitamin E can reduce the incidence of cisplatin-induced PN by 50%. In this study, the investigators aimed to determine if vitamin E could also prevent Ox-induced acute PN

Primary Outcome Measures:
  • Incidence and grade of Peripheral neuropathy by common terminology criteria for adverse events v 3.0(CTCAE)and specific Ox PN gradation scales. [ Time Frame: Within the first 45 days (plus or minus 7 days) of treatment ( 3 x oxaliplatin infusions) ]

Enrollment: 38
Study Start Date: August 2009
Study Completion Date: December 2010
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Control Group
Five days before chemotherapy:1 x daily Used until one week after third oxaliplatin infusion: 1 x daily
Drug: Placebo
Placebo, given orally
Other Names:
  • Calcium gluconate 1g, IV, before and after oxaliplatin
  • Magnesium sulfate 1g, IV, before and after oxaliplatin
Experimental: Vitamin e
Five days before chemotherapy:1 x daily Used until one week after third oxaliplatin infusion: 1 x daily
Drug: Vitamin E
Vitamin E 400mg PO orally
Other Names:
  • Calcium gluconate 1g, IV, before and after oxaliplatin
  • Magnesium sulfate 1g, IV, before and after oxaliplatin

Detailed Description:
This was a prospective, phase II, randomized pilot study. Patients were randomized 5 days before the start of Ox to receive either vitamin E at 400 mg daily or placebo, until after the end of the Ox-based chemotherapy regimen. The investigators evaluated PN intensity using the CTCAE version 3 and specific Ox PN gradation scales. The investigators included patients with colorectal and gastric cancers scheduled to receive Ox-based chemotherapy. Both groups received calcium and magnesium supplements before and after oxaliplatin infusions.
