Abstract:〔Abstract〕 Objective To explore the effects of nutritional status on clinical outcomes and side effects of concurrent chemoradiotherapy for cervical cancer patients. Methods A total of 60 patients with cervical cancer who received concurrent chemoradiotherapy in the Third People's Hospital of Luoyang from March 2018 to May 2020 were selected and divided into normal nutrition group with 32 cases and abnormal nutrition group with 28 cases according to their nutritional status. After 1 cycle of treatment, the incidence of adverse reactions between the normal nutrition group and the abnormal nutrition group was compared, and the abnormal nutrition group was divided into the intervention group with 15 cases and the non-intervention group with 13 cases according to whether nutritional intervention was accepted. The incidence of adverse reactions between the intervention group and the non-intervention group and the clinical outcomes of the normal nutrition group and the non-intervention group after 1 year were compared. Results The incidences of bone marrow suppression, renal impairment and gastrointestinal reactions in the normal nutrition group were lower than those in the abnormal nutrition group, and the differences were statistically significant (P < 0.05). The incidences of bone marrow suppression, renal impairment and gastrointestinal reactions in the intervention group were lower than those in the non-intervention group, with statistical significances (P < 0.05). The incidence of adverse clinical outcomes in the normal nutrition group was 3.23%, significantly lower than 23.08 % in the non-intervention group, the difference was statistically significant (P < 0.05). Conclusion The good nutritional status can reduce side effects of concurrent chemoradiotherapy in patients with cervical cancer and improve the clinical outcome, and positive and effective nutritional intervention in patients with malnutrition can reduce the side effects of treatment.
