Abstract:ObjectiveTo investigate the prevalence of nutrition risk and malnutrition in cancer patients hospitalized for radiotherapy. Methods We involved 330 patients with malignant tumors who were admitted to the radiotherapy center from August to October 2017 in Chongqing University Cancer Hospital. The nutrition risk was evaluated by the nutritional risk screening 2002 (NRS 2002),the nutritional status was assessed with the patient-generated subjective global assessment (PG-SGA) questionnaire, the Karnofsky performance status (KPS)was used to evaluate the physical status. Physical indexes and laboratory examination results were recorded within 48 hours after admission. ResultsA total of 330 patients completed the nutritional survey. There were 227 males and 103 females, accounting for 68% and 31.2%, respectively. The mean age was 54.0±11.4 years old. 28.8% of the patients had nutritional risk (score≥3),according to the PG-SGA score, 52.7% had the malnutrition (PG-SGA score≥4). Among different cancers, patients with nasopharyngeal cancer had the highest prevalence of nutritional risk (29.3%), the nutritional risk was 28.1%,18.1% and 15.2%, respectively, for patients with lung cancer, oral cancer and esophageal cancer who intending to accept radiotherapy. There was a negative correlation between BMI and PG-SGA score, a positive correlation between the NRS 2002 score and the PG-SGA score. Age (≥65 years), albumin (<40g/L), prealbumin (<150g/L), Karnofsky (<80) are the risk factors of nutritional risk and severe malnutrition (P<0.05). ConclusionThe prevalence of nutritional risk in patients with radiotherapy was medium, but the prevalence of malnutrition in patients with radiotherapy was high. Nutrition management of the patients was very necessary for cancer patients receiving radiotherapy. In clinical practice, combined with the nutritional status of patients, PG-SGA score can be used as a reference standard for nutritional intervention.
