OBJECTIVE: In this study, we aimed to evaluate the prognostic value of preoperative serum ferritin level in patients with stage 2 colon cancer who underwent curative surgery. PATIENTS AND METHODS: The data of 120 patients who were stage 2 after curative surgery and whose ferritin levels were measured at the time of diagnosis without starting any treatment were analyzed. Demographic data such as age and gender, histopathological characteristics such as tumor size, lymphovascular invasion (LVI), perineural invasion (PNI), number of removed lymph nodes, tumor grade, and clinical and laboratory data were retrieved from the hospital medical charts or electronic medical records. In the survival analysis, the cut-off level of ferritin was accepted as 150 ng/ml, which is the upper limit determined by the World Health Organization (WHO), as a prognostic factor. RESULTS: Fifty (41.7%) of the patients were female, 70 (58.3%) were male, and the median age was 63.5 (range 24-90) years. There was no significant difference between the low and high ferritin groups regarding age, gender, T stage, tumor localization, histological subtype, PNI, LVI, removal of less than 12 lymph nodes, and tumor size. Disease-free survival and overall survival of patients with high ferritin levels were worse than patients with low ferritin levels, but this difference did not reach statistical significance. CONCLUSIONS: Serum ferritin level is an easily monitored, cost-effective, and reproducible marker. İn this study we found that high ferritin level was associated with poor survival, although it was not statistically significant.
