Aim and Background Preparation of the patients for liver transplantation is a meticulous process and includes evaluation of tumor markers to rule out occult malignancy. The present study evaluated the significance of serum tumor markers in patients bound for liver transplantation due to viral and other etiologies of liver failure. Patients and Methods Three hundred eighty-one patients who underwent liver transplantation were included in the study. Demographic data, model for end stage liver disease (MELD) scores, and serum tumor marker levels were prospectively collected. Results AFP levels were significantly higher in viral etiologies when compared to other etiologies (p < 0.05). Ca 19-9 was significantly higher in viral etiologies (p < 0.05). Among the viral etiologies, HCV-related liver failure had higher carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (Ca 19-9) levels (p < 0.05). A correlation was found between increasing MELD scores and serum levels of tumor markers (p < 0.05). Conclusions Tumor markers such as AFP, CEA, Ca 125, and Ca 19-9 can be elevated in end stage liver disease. Their levels vary according to etiology and severity of disease. The diagnostic capabilities of these markers are reduced in end stage liver disease setting but they contribute to the evaluation of the pathophysiology of chronic liver disease. Transplantation can be performed safely in cases with high tumor marker levels provided that any occult malignancy is ruled out by means of imaging and endoscopic techniques. Tumor markers can guide the physician in determining the severity of liver cirrhosis, and further studies are needed to validate such a relationship.
