Effects of enteral nutrition intervention on immune nutritional status and radiation damage in patients with esophageal cancer radiotherapy

摘要

Objective: To study the effects of enteral nutrition intervention on immune nutritional status and radiation damage in patients with esophageal cancer radiotherapy. Methods: Patients with esophageal cancer who underwent radiotherapy in West China Hospital, Sichuan University between January and October 2017 were chosen as the research subjects and divided into the experimental group who received enteral nutrition intervention and the control group who received routine intervention. The contents of nutrition indicators and radiation damage markers in serum as well as the contents of immune cells in peripheral blood were determined before radiotherapy and after radiotherapy ended. Results: Compared with those before radiotherapy, serum ALB, PA, TRF and RBP contents as well as peripheral blood Th cell, NK cell, Breg cell and Treg cell contents of experimental group did not change significantly while serum PDGF-BB, TGF-β1, CTGF, TNF-α and SAA contents were significantly higher after radiotherapy; serum ALB, PA, TRF and RBP contents as well as peripheral blood Th cell and NK cell contents of control group were significantly lower while serum PDGF-BB, TGF-β1, CTGF, TNF-α and SAA contents as well as peripheral blood Breg cell and Treg cell contents were significantly higher after radiotherapy; serum ALB, PA, TRF and RBP contents as well as peripheral blood Th cell and NK cell contents of experimental group after radiotherapy were higher than those of control group while serum PDGF-BB, TGF-β1, CTGF, TNF-α and SAA contents as well as peripheral blood Breg cell and Treg cell contents were lower than those of control group. Conclusion: enteral nutrition intervention can improve immune nutritional status and reduce radiation damage in patients with esophageal cancer radiotherapy.
