Feasibility of a Virtually Delivered LASO-3 Diet Intervention for Chemotherapy Induced Peripheral Neuropathy in Post-Treatment Cancer Survivors

Summary

This clinical trial studies whether a virtually delivered diet intervention focused on lower added sugar, higher fiber, and higher omega 3 fatty acid (LASO-3) can be used to improve chemotherapy-induced peripheral neuropathy (CIPN) in cancer survivors after treatment. Cancer survivors often experience CIPN during and after cancer treatment with neurotoxic chemotherapy. CIPN is characterized by nerve damage from chemotherapy that leads to numbness, tingling, or pain in the hands or feet. However, there are few treatments to manage CIPN. Inflammation contributes to the development of CIPN and dietary patterns that have been demonstrated to improve diet quality and reduce inflammation in cancer survivors may be promising for use as a CIPN management strategy. The LASO-3 diet intervention consists of virtually delivered nutrition education sessions provided by a Registered Dietitian. The sessions focus on three dietary goals, informed by the United States Dietary Guidelines for Americans: 1) lowering added sugar intake to \< 10% of daily calories, 2) increasing daily fiber intake to ¿ 20 grams, and 3) increasing intake of moderate-high omega-3 seafood to three or more servings weekly or 3300-3400 mg/day of alpha-linolenic acid (e.g., plant-based sources include canola or flaxseed oil, walnuts, or flaxseed or chia seeds). The Registered Dietitian tailors the sessions to the patient based on information and feedback obtained throughout the sessions. The LASO-3 diet intervention may be an effective way to improve CIPN in cancer survivors after treatment.
