Research Advances of Platelet-to-Lymphocyte Ratio in Liver Disease

血小板/淋巴细胞比值(Platelet-to-Lymphocyte Ratio, PLR)作为一种反映全身性炎症标志物，因其易于获取、计算方法简便以及成本较低等优势，在肝脏疾病的研究中受到广泛关注。本文综述了PLR在病毒性肝炎、非酒精性脂肪性肝病、肝硬化以及原发性肝癌等方面的研究进展，重点关注其在疾病监测和预后评估中的潜在应用价值。Platelet-to-lymphocyte ratio (PLR), as a marker of systemic inflammation, has attracted much attention in the study of liver diseases due to its easy accessibility, simple calculation method and low cost. In this article, we review the research progress of PLR in viral hepatitis, non-alcoholic fatty liver disease, liver cirrhosis, and primary liver cancer, focusing on its potential application in disease monitoring and prognostic assessment.
