    Background/Purpose: This study aimed to directly compare the utility of liver stiffness (LS) and spleen stiffness (SS) at sustained virologic response (SVR) for predicting hepatocellular carcinoma (HCC) and non-HCC events in patients with chronic hepatitis C (CHC) after direct-acting antiviral therapy.MethodsThis retrospective study included 695 CHC patients who achieved SVR and underwent LS and SS measurements. LS and SS were measured using point shear wave elastography and compared head-to-head.ResultsDuring a median follow-up of 29.5 months, 49 (7.1%) patients developed liver-related events (LREs), including 28 HCC and 22 non-HCC events after SVR. Multivariable Cox regression analysis revealed that age, albumin level, and LS (≥ versus <1.46 m/s) at SVR (adjusted hazard ratio [aHR]: 5.390; 95% confidence interval [CI]: 2.349-12.364; p < 0.001), but not SS at SVR, significantly predicted the overall risk of post-SVR LREs (n = 49). Furthermore, age and LS (≥ versus <1.46 m/s) at SVR (aHR: 6.759; 95% CI: 2.317-19.723; p < 0.001), but not SS at SVR, independently predicted the risk of post-SVR incident HCC. In contrast, SS (≥ versus <2.87 m/s) at SVR (aHR: 11.212; 95% CI: 1.564-20.132; p = 0.021) and albumin level, but not LS at SVR, significantly predicted the risk of post-SVR non-HCC events.ConclusionPost-SVR LS better predicts HCC risk. Post-SVR SS helps predict non-HCC risk after antiviral therapy for CHC. LS and SS at SVR provide complementary prognostic information regarding risks of HCC and non-HCC events in the post-SVR setting. Further validation is warranted in larger cohorts.Copyright © 2024 Formosan Medical Association. Published by Elsevier B.V. All rights reserved.
