These models include: the recurrence clinical risk score from Lee et al. [39], the Shanghai score from Sun et al. [40], the recurrence score for hepatitis B virus-related HCC proposed by Qin et al. [41], a RFS nomogram for AFP-negative patients created by Gan et al. [42], early recurrence after surgery for liver tumor models built by Chan et al. [5], the Hong Kong recurrent model developed by Ng et al. [8], the recurrence after curative hepatectomy score constructed by Tokumitsu [43], and some radiomics-based prognostic prediction models [44–47]. The gene discussed is AFP; the disease is hepatocellular carcinoma.
