Nutritional status in advanced pancreatic cancer

Background. Exocrine pancreatic insufficiency (EPI) occurs in most patients with advanced pancreatic cancer (PC) and even more often when a tumor is localized in the head of the pancreas. However, insufficient attention is paid to the diagnosis of EPI and assessment of nutritional status, which negatively affects the results of treatment. Materials and methods. One hundred fifty eight patients with primary diagnosed locally advanced and metastatic PC were included in the retrospective study. We used the calculation of the odds ratio with 95% CI with an assessment of the p value using the Pearson chi 2 test to compare the incidence of clinical and laboratory parameters of nutritional status with values below the lower limit of normal (LLN) depending on the location of the tumor in the pancreas. Results. Fecal elastase test was performed in only 19 (12%) patients. In this group, the incidence of EPI was 73.6%. Pancreatic enzyme replacement therapy in the minimal sufficient dose was prescribed in 17.1% of the general cohort. The level of hemoglobin, erythrocytes and albumin below the LLN was found in patients with the tumor in the pancreatic head, respectively, 2.742 (95% CI 1.27-5.92), 3.788 (95% CI 1.554-9.232) and 9.767 (95% CI 1.255-76.027) times more often than in patients with cancer in the body -tail of the pancreas. In patients with the tumor in the pancreatic head, the lower levels of hemoglobin (median 125 g/l vs 132 g/l, respectively), erythrocytes (4.19 mil/mu l vs 4.51 mil/mu l), total protein (69.6 g/l vs 71.5 g/l), and albumin (40.1 g/l vs 42 g/l), as well as the values of nutritional indices: prognostic nutritional index, nutritional risk index, hemoglobin, albumin, lymphocyte and platelet ratio index, and prognostic immune nutritional index were observed. Conclusion. Diagnosis and treatment of EPI remains inadequately attended. The values of nutritional status parameters in patients with PC in the head are lower than in patients with a tumor in the body -tail of the pancreas, which reflects the contribution of EPI.
