Baseline Tumor-Specific Prognosis in Early-Stage Hepatocellular Carcinoma: Time-Dependent Role of Biomarker Profile and Modified ALBI Grade
Kelley Núñez, Juan Gimenez, Ari J. Cohen, Jeffrey Burton, Tyler Sandow, Paul ThevenotBackground/Objectives: Identifying aggressive tumor biology within early-stage hepatocellular carcinoma (HCC) remains challenging. Scores based on liver function, systemic inflammation, and HCC biomarkers have been linked to overall survival prognosis; however, the combined ability of these scores to assess tumor-specific prognosis in early-stage disease is unclear. In this single-center, prospective study, biomarker profiling with AFP, AFP-L3, and DCP, along with modified albumin–bilirubin (mALBI), and neutrophil–lymphocyte ratio (NLR)/platelet–lymphocyte ratios (PLRs) were evaluated to determine their prognostic role in assessing clinical manifestations of aggressive biology by stratifying HCC progression risk. Methods: Indices and biomarkers were assessed at BCLC-A-stage HCC diagnosis and prior to liver-directed therapy (LDT). The primary prospective study endpoint was time-to-advanced-stage tumor progression (TTP). Results: The cohort included 232 patients diagnosed with early-stage HCC who underwent treatment with LDT. A multivariate model revealed that mALBI grade (p = 0.021), cumulative lesion size (p = 0.005), and elevations in HCC biomarkers (p < 0.001) were associated with TTP. Biomarker profile stratified TTP (p < 0.001) in which patients with complex profiles (3+) had 1-year progression risks of 69%. The biomarker system retained the ability to stratify TTP within small (≤3 cm) and large (>3 cm) cumulative tumor burden (p < 0.001, p = 0.005). While PLR was not prognostic for TTP, NLR disappeared from the multivariate model and mALBI stratified long-term progression risk (p = 0.003). In low-complex biomarker patients (0–1+), mALBI stratified progression risk (p = 0.001). Conclusions: Multi-positive biomarker profiling in early-stage HCC identifies a population with clinical manifestations of aggressive tumor biology at high risk of rapid post-treatment disease progression that may benefit from more aggressive treatment approaches. In patients with low-risk biomarker profiles (0–1+), mALBI can assess longer-term (>1-year) post-treatment disease progression risk, while scores based on systemic inflammation were not associated with tumor-restricted outcomes.
