ABSTRACT
The aim of this study was to assess and analyze the nutritional status of gastric cancer (GC) patients. The analysis included 207 patients with GC treated in a large center of oncology. Patients were divided into two groups according to the cutoff value of the mean prognostic nutritional index (PNI): those with a PNI < 52.78 and those with a PNI ≥ 52.78. The higher PNI was associated with lower age and higher total protein and hemoglobin levels (P < 0.01). The total lymphocyte count (P = 0.02), albumin, total protein and PNI (P < 0.01) were significantly higher in stable-weight patients and lower in the group with weight loss > 10% (P = 0.000031). Body mass index (BMI) after disease recognition, albumin and total protein (0.003) levels, total lymphocyte count, and PNI were significantly lower in patients with nutritional risk. Significantly lower BMI before disease and BMI after disease recognition were noted in smoking patients. Significantly higher total lymphocyte count was observed in smoking patients (P < 0.01). Significantly lower PNI was noted in tumors with lymph node metastasis (N+). G3 tumors were associated with the lowest total lymphocyte count (P = 0.01). Assessment of nutritional status using PNI calculation should be the standard management of patients with GC before treatment.
