  • This study aimed to assess the effect of irinotecan / 5-fluorouracil treatment on amount and types of fatty acids in skeletal muscles of tumor-bearing rats fed: a) control diet, b) fish oil diet. Rats bearing the Ward colorectal carcinoma were fed a semi-purified diet with or without fish oil prior to receiving chemotherapy. Gastrocnemius muscles were isolated 7 days later. Lipids were extracted and triglycerides (TG) and phospholipid (PL) separated by thin layer chromatography, and fatty acids (FAs) quantified by gas liquid chromatography. Rats receiving chemotherapy exhibited the most TG-FA in muscle tissue. Rats fed the fish oil diet exhibited lower total muscle TG compared with other groups. N-3 FA content in muscle TG and PL were higher in the fish oil group compared to other groups. This study suggests that fish oil modifies the fat accumulation in muscle that occurs during chemotherapy.
