AIM: The aim of this study was to determine factors affecting overall mortality in patients over 60 years of age who
underwent surgery for gastric cancer in our clinic.
MATERIAL AND METHODS: Data on histopathological diagnosis (tumor size, lymph node status, and number), pathological
stage, serum albumin level, tumor markers, complete blood count, and demographic information of 109 patients
over 60 years of age who had surgery for gastric cancer between January 2011 and July 2016 were obtained retrospectively
from the patient files. In addition, the survival status of all patients were examined and recorded. Metastatic
lymph node ratio (MLR), red cell distribution width platelet ratio (RPR), neutrophil-lymphocyte ratio (NLR), plateletlymphocyte
ratio (PLR), and prognostic nutritional index (PNI) were calculated.
RESULTS: On univariate analysis of independent parameters, pathological LN number (p = 0.001), MLR (p <0.001), T3 (p = 0.001) or T4 (p = 0,006) tumor stage according to TNM system, the presence of metastasis (p = 0.063), and male gender (p = 0.066) were found to affect overall mortality (OM). On multivariable Cox regression analysis of these results, MLR (p = 0.005) and T stage (p = 0.006) was determined to be a statistically significant and independent prognostic value. CONCLUSION: In patients over 60 years of age who underwent surgery for gastric cancer, the factors affecting mortality were determined to be the presence of metastases, number of pathological lymph nodes, and male gender. Metastatic lymph node ratio and T1&T2 stage were determined to be independent prognostic factors.
