Abstract
Background/Aim: Hepatic resection for Barcelona Clinic Liver Cancer (BCLC) stage B (intermediate-stage) hepatocellular carcinoma (HCC) is not recommended by BCLC treatment algorithms. We sought to develop a new prognostic model for determining appropriate treatment strategies in patients with intermediate-stage HCC. Patients and Methods: This single-center retrospective study included patients who underwent hepatic resection for HCC between 2000 and 2018. A total of 498 patients were classified according to the BCLC staging system (0, n=116; A, n=319; B, n=63). The predictive impact for surgical outcomes was evaluated using receiver operating characteristic (ROC) curves. Based on a survival outcome probability formula, a new predictive model was established. Results: The preoperative albumin level and platelet count were the strongest diagnostic values in patients with intermediate-stage HCC (areas under the ROC curves, AUCs: 0.710 and 0.676, respectively). Logistic regression analysis provided the albumin–platelet index [API; 156.2×albumin (g/dl)+platelet count (×109/l)] was defined as a new prognostic model for the probability of poor survival. The optimal cutoff value (781.2; AUC 0.755) divided patients with BCLC-B into B1 (>781.2, n=27) and B2 (≤781.2, n=36) categories. Patients in substage B2 had a significantly worse prognosis than patients in other stages (p<0.0001), whereas there was no difference in prognosis between patients in substage B1 and those in other stages. Conclusion: The API stratifies prognosis in patients with intermediate-stage HCC. For subgroup B1, hepatic resection can be considered a radical treatment, even for intermediate-stage HCC.
