摘要
Hand–foot syndrome (HFS) is a common adverse effect of capecitabine affecting the quality of life of cancer patients. To enhance the tolerability of capecitabine, this work evaluated the incorporation of quercetin into topical collagen matrix formula to target thymidine phosphorylase enzyme, oxidative stress, and apoptosis underlying HFS. Forty Sprague Dawley rats were allocated to four equal groups. The control group received distilled water orally. HFS was induced by oral capecitabine (200 mg/kg/day) for 21 days. The untreated HFS group received no treatment. In the treated groups, topical collagen and quercetin-incorporated collagen matrix formula were administered concomitantly with the HFS induction protocol. Treatment with quercetin-incorporated collagen matrix showed a significant decrease in thymidine phosphorylase level compared with the untreated and collagen-treated groups. Treatment with quercetin-incorporated collagen matrix showed a significant decrease in malondialdehyde and caspase-3 levels, and a significant increase in the total antioxidant capacity of the skin and B cell lymphoma/leukemia 2 levels compared with the untreated group. Additionally, a significant improvement in the gross picture and histopathological score of HFS was observed. In conclusion, the quercetin-incorporated collagen matrix is a promising formula for the prevention of HFS, due to the targeted effect on thymidine phosphorylase and subsequent antioxidant and antiapoptotic effects.
