Application value of NRS2002 and PG-SGA in nutritional assessment for patients with cervical cancer surgery

This study explored and analyzed the application value of nutritional risk screening 2002 (NRS2002) and patient-generated subjective nutrition assessment (PG-SGA) in nutritional assessment for patients with cervical cancer surgery.

A total of 165 cervical cancer patients that received elective cervical cancer surgery from February 2017 to December 2019 were chosen as the research subjects. NRS 2002 and PG-SGA were employed to evaluate the nutritional status of patients, and detect their nutrition-related laboratory examination indexes. By using albumin (ALB)≤30 g/L as the criterion of malnutrition, the accuracy of NRS2002 and PG-SGA in evaluating the nutritional status of patients was analyzed.

The differences between scores of NRS2002 and PG-SGA in age, BMI, tumor stage, pelvic lymph node metastasis were statistically significant (P<0.05); while the difference between scores of NRS2002 and PG-SGA in different education degree, pathological type and growth type of patients was statistically insignificant (P>0.05). By using ALB≤30 g/L as the gold standard to determine malnutrition, 64 malnourished patients were detected, with a detection rate of 38.79%. Compared with this gold standard, the judgment of NRS 2002 and PG-SGA have high consistency with the gold standard, and the Youden indexes were 0.550 and 0.795 respectively. In addition, the nutritional or malnutrition risk of cervical cancer patients was assessed by NRS2002 and PG-SGA, respectively. Among them, 33 patients received co-diagnosis, the results had remarkably correlation (P<0.05) with contingency coefficient r of 0.523.

Both NRS2002 and PG-SGA are suitable for preoperative nutritional risk screening of patients with cervical cancer surgery. PG-SGA has a higher positive rate but poor time requirement than that of RS2002. Therefore, clinicians can choose the appropriate tool on the basis of an individual patient's situation for nutritional assessment.
