Randomized Placebo-Controlled Trial of Glutamine for Breast Cancer Patients With Peripheral Neuropathy

1. Determine whether oral glutamine supplementation can reduce the symptoms and signs of peripheral neuropathy. 2. Determine whether alterations in the symptoms and signs of peripheral neuropathy are correlated with an alteration of circulating nerve growth factor or insulin-like growth factor levels. 3. Assess whether oral glutamine affects circulating nerve growth factor or insulin-like growth factor levels. 4. Assess whether glutamine interferes with paclitaxel pharmacokinetics
