Abstract:Objective To discuss the importance of nutritional intervention in tolerance of tumor patients to radiotherapy. Methods This study included 60 patients treated in the Third Ward of Radiotherapy in the Tumor Hospital Affiliated to Harbin Medical University between May 3 and June 30, 2016. They were divided into experiment group and control group with 30 cases in each. The experimental group had regular diet guidance and nutrition support. Results When the patients were discharged from hospital, there was no statistical difference in WBC, RBC, serum prealbumin value or incidence of radiotherapy interruption days between the two groups (p > 0.05), while serum albumin level and incidence of adverse reactions of the experimental group were significantly higher than those of the control group (p < 0.05). Conclusions Nutritional intervention is very important for better tolerance to radiotherapy, improvement of the quality of life, and alleviation of adverse reactions in tumor patients.
