The analysis of four chosen nutrition status indicators showed that Body Mass Index was not a reliable indicator of malnutrition of patients with alimentary tract carcinoma. Ratio of malnourished patients, who underwent surgery R0, R1 was lower than those with R2 or nonresection in each studied group. There is a significantly smaller number of patients with elements of malnutrition among those subjected to R0, R1 surgery than R2 and nonresection \(p=0.00005\). In the pancreas and colon cancer groups these differences are not significant \(p=0.08 and p=0.44 respectively\). Postoperative complications were observed in each studied group. The biggest ratio of complications concerned the pancreas cancer group \(61.11%\), then stomach cancer \(39.36%\) and colon cancer group \(37.9%\). \; The relation between nutrition status of patients with stomach, pancreas and colon cancer on their admission day with prevalence of postoperative complications were studied using three indicators\: percentage body mass loss, albumin level and total number of lymphocytes. It was observed that patients with stomach cancer, with body mass loss \(p=0.005\) and lower level of albumins \(p=0.001\) were at bigger risk of postoperative complications. However, patients"]
