Virtual LASO-3 diet program to ease chemotherapy-related numbness and tingling

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

Not applicable Interventional University of Michigan Rogel Cancer Center · NCT07365007

This trial tests whether a virtual diet program that lowers added sugar and increases fiber and omega-3s can help cancer survivors who have numbness, tingling, or pain after neurotoxic chemotherapy.

What this trial studies

This interventional study delivers the LASO-3 diet program virtually through nutrition education sessions led by a Registered Dietitian, with goals of lower added sugar, higher fiber, and increased omega-3 intake based on U.S. Dietary Guidelines. Participants are cancer survivors at least three months after their last neurotoxic chemotherapy who report at least moderate numbness and tingling and can participate in English-language online sessions. The study collects surveys, interviews, biospecimens, and electronic health record data to measure changes in chemotherapy-induced peripheral neuropathy symptoms and related biomarkers. Individuals with pre-existing neuropathy, routine anti-inflammatory drug or steroid use, or high baseline fish/omega-3 intake are excluded to isolate the diet effect.

Who should consider this trial

Good fit: Ideal candidates are English-speaking adult cancer survivors at least three months after neurotoxic chemotherapy who report moderate or worse numbness and tingling and have internet access for virtual sessions.

Not a fit: Patients with pre-existing non-chemotherapy neuropathy, active inflammatory disease, routine NSAID/steroid use, or already high fish/omega-3 intake are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the diet program could reduce neuropathy symptoms and improve daily function and quality of life for cancer survivors with CIPN.

How similar studies have performed: Dietary patterns that reduce inflammation and increased omega-3 intake have shown promise for symptom reduction in related contexts, but using a targeted virtual LASO-3 program specifically for CIPN is relatively novel with limited prior trial evidence.
