OBJECTIVES:
Primary
* To assess the feasibility of dietary flaxseed (FS) supplementation in patients undergoing definitive chemoradiotherapy for locally advanced or metastatic non-small cell lung cancer.
* To collect toxicity and tolerability data on dietary FS supplementation during definitive chemoradiotherapy.
Secondary
* To validate urinary and serum markers of oxidative stress and FS lignan levels as surrogates of the bioavailability of FS in these patients.
* To determine if a dose response to daily ingestion of 20 g or 40 g of FS can be observed in plasma lignan levels and urinary markers of oxidative stress.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
* Arm I: Patients consume flaxseed muffins once or twice daily beginning on the first day of radiotherapy and continuing for up to 9-10 weeks.
* Arm II: Patients consume placebo muffins once or twice daily beginning on the first day of radiotherapy and continuing for up to 9-10 weeks.
Blood and urine samples are collected periodically for biomarker studies.
After completion of study treatment, patients are followed up for 1 month.
