Liver Cancer Diagnosis: Tumor Markers, Imaging Studies, and the Role of AFP in Cirrhosis

The diagnosis of liver cancer, particularly hepatocellular carcinoma (HCC), presents a clinical challenge that necessitates a multidisciplinary approach. Early detection is crucial for improving prognosis and the availability of curative therapies. In this context, tumor markers and imaging studies play a fundamental role in the identification and management of this disease.
Diving Deeper into Diagnosis
The use of tumor markers such as alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9 (CA19-9) has proven useful in the diagnosis of HCC. A recent study demonstrated that the combination of these markers with computed tomography (CT) significantly enhances the specificity and sensitivity of the diagnosis, surpassing the individual detection of each marker [1]. Additionally, liver ultrasound combined with AFP is a commonly used surveillance strategy, although its effectiveness may vary depending on the clinical context [2].
Magnetic resonance imaging (MRI) and multiphasic CT are valuable tools for the early detection of HCC, especially in patients with underlying cirrhosis. These imaging modalities have shown a higher detection rate in early stages compared to ultrasound alone [3]. Furthermore, the combination of imaging techniques with tumor markers such as AFP and CA19-9 has demonstrated improved diagnostic accuracy [4].
Conclusions
The diagnosis of liver cancer greatly benefits from a combined approach that includes both tumor markers and imaging studies. The integration of these tools allows for more accurate and early detection, which is crucial for the effective management of HCC. As technology advances, it is likely that new biomarkers and imaging techniques will emerge, further enhancing our ability to diagnose this disease in a timely and precise manner.
