Introduction

Alpha-fetoprotein (AFP) is a glycoprotein produced primarily by the fetal liver and yolk sac during development, playing a crucial role in fetal growth and development. In adults, AFP levels are typically low, but elevated levels can serve as important biomarkers in diagnosing and monitoring various liver diseases, particularly hepatocellular carcinoma (HCC), and certain germ cell tumors [1].

In the context of liver disease, AFP is most commonly associated with HCC, a primary liver cancer that often arises in the setting of chronic liver disease, such as hepatitis B or C infections and cirrhosis. Elevated AFP levels are found in approximately 60-70% of patients with HCC, making it a valuable tool for early detection [2]. When combined with imaging techniques like ultrasound or computed tomography (CT), AFP testing can enhance the accuracy of HCC diagnosis, enabling timely interventions that can significantly improve patient outcomes [3].

The interpretation of AFP levels is not straightforward; while a high AFP can indicate the presence of liver cancer, it is not exclusively diagnostic [4]. Elevated AFP can also occur in benign liver diseases, such as hepatitis, cirrhosis, and liver regeneration, as well as in other malignancies, such as germ cell tumors and certain gastrointestinal cancers. Thus, clinicians must consider the entire clinical picture, including imaging results and patient history, when using AFP as a diagnostic marker [5].

Prognostically, AFP levels have been linked to the severity and progression of liver disease. Higher baseline AFP levels are associated with poorer outcomes in HCC patients, reflecting tumor burden and aggressiveness [6]. Monitoring AFP levels post-treatment can also provide insights into disease recurrence. A rising AFP level after curative treatment often signals disease relapse, allowing for timely intervention [7].

In addition to HCC, AFP is an important marker in prenatal medicine. Elevated AFP levels during pregnancy can indicate potential fetal abnormalities, such as neural tube defects or abdominal wall defects, leading to further evaluation and management strategies [8].

Recent advancements in research are expanding the utility of AFP beyond traditional roles. Novel biomarkers and imaging techniques are being explored to improve diagnostic accuracy and prognostic stratification in liver disease and cancer [9]. Ongoing studies aim to refine the use of AFP in clinical practice, optimizing its application in conjunction with other biomarkers to enhance patient care [10].

Conclusion

AFP serves as a critical biomarker in diagnosing and monitoring liver diseases and cancer. Its role in clinical practice underscores the importance of early detection and effective management strategies, ultimately improving patient outcomes in conditions associated with elevated AFP levels.
