Risk stratification of primary liver cancer

World J Clin Cases. 2022 Sep 16;10(26):9545-9549. doi: 10.12998/wjcc.v10.i26.9545.


The risk stratification of primary liver cancer (PLC) discussed in a review of viral hepatitis and PLC could lead to misunderstandings by readers. For example, a single study or a small number of studies cannot comprehensively summarize the risk factors of PLC, is not included in the family history of liver cancer, and chronic hepatitis D is listed as a medium risk factor for the development of PLC. Currently, PLC prediction models with good clinical validation values have been applied clinically, such as the Toronto hepatocellular carcinoma risk index, REACH-B model, and PAGE-B model. Therefore, the Chinese, together with several research societies, have formulated the "Guideline for stratified screening and surveillance of primary liver cancer (2020 edition)." This guideline outlines PLC screening in at-risk populations, both in hospitals and communities. It is recommended to stratify the at-risk population into four risk levels: low-, intermediate-, high-, and extremely high-risk. This is highly recommended and applied in clinical practice.
