This study evaluated whether combining radiographic tumor burden score (TBS) and alpha-fetoprotein (AFP) level could stratify overall survival (OS) among hepatocellular carcinoma (HCC) patients after liver resection (LR). The results showed that the combination of TBS and AFP levels could effectively predict the overall survival of HCC patients.
Simple Summary The tumor burden score (TBS) is calculated using the Pythagorean theorem based on the largest tumor size and tumor number (alpha(2) + beta(2) = gamma(2), where alpha is the largest tumor size, beta is the tumor number, and gamma is the TBS). Patients who underwent liver resection (LR) for Barcelona Clinic Liver Cancer stage 0, A, or B hepatocellular carcinoma (HCC) between 2011 and 2018 were enrolled. Among 743 patients, 193 (26.0%) patients had a low TBS (<2.6), 474 (63.8%) had a moderate TBS (2.6-7.9), and 75 (10.1%) had a high TBS (>7.9). Combining radiographic TBS and alpha-fetoprotein levels could stratify overall survival among HCC patients after LR. We evaluated whether combining the radiographic tumor burden score (TBS) and alpha-fetoprotein (AFP) level could be used to stratify overall survival (OS) among hepatocellular carcinoma (HCC) patients after liver resection (LR). Patients who underwent LR for Barcelona Clinic Liver Cancer stage 0, A, or B HCC between 2011 and 2018 were enrolled. TBS scores were calculated using the following equation: TBS2 = (largest tumor size (in cm))(2) + (tumor number)(2). Among 743 patients, 193 (26.0%) patients had a low TBS (<2.6), 474 (63.8%) had a moderate TBS (2.6-7.9), and 75 (10.1%) had a high TBS (>7.9). Those with a TBS <= 7.9 and AFP < 400 ng/mL had a significantly better OS than those with a TBS > 7.9 and an AFP < 400 ng/mL (p = 0.003) or >= 400 ng/mL (p < 0.001). A multivariate analysis using TBS <= 7.9 and AFP < 400 ng/mL as the reference values showed that a TBS > 7.9 and an AFP < 400 ng/mL (hazard ratio (HR): 2.063; 95% confidence interval [CI]: 1.175-3.623; p = 0.012) or >= 400 ng/mL (HR: 6.570; 95% CI: 3.684-11.719; p < 0.001) were independent predictors of OS. In conclusion, combining radiographic TBSs and AFP levels could stratify OS among HCC patients undergoing LR.
