Role of CA 19.9 and CEA in predicting diagnosis in hepatocellular carcinoma.

Background: Hepatocellular carcinoma (HCC) is responsible for 90% of cases of primary liver cancer and is also responsible for the fourth most common cause of cancer death worldwide. To improve the current scenario for the early diagnosis and management of HCC patients, a better understanding of HCC is required. Hence, serum tumor biomarkers such as CA 19-9 (cancer antigen), CEA (carcinoembryonic antigen), and AFP (alpha-fetoprotein) show promising future, when it comes to early diagnosis of primary liver cancer (PHC), liver cirrhosis, and metastasis.

Methods: It was a retrospective cross-sectional analysis of patients diagnosed with primary hepatocellular carcinoma, data were collected from the hospital database and included a total of 245 patients of HCC attending the out-patient department and some were admitted for treatment at our institution. Out of 245 patients, 68 patients were selected for the study. We have collected information related to the patient's demographic profile, pathological diagnosis, biochemical profile, and even radiological diagnosis. The sensitivity and specificity of CA 19-9 and CEA were also done.

Results: Adenocarcinoma is the most common type of liver cancer followed by HCC. We have shown a weak correlation between tumor markers CA 19-9 and CEA for the diagnosis of liver carcinoma. Further our study shows that the sensitivity of tumor marker CA 19-9 for the diagnosis of liver carcinoma is 64.28% and that of CEA is 83.67%.

Conclusion: The search for a novel biomarker of early liver carcinoma requires further research.
