AFP and neoplasm: The PS was calculated using logistic regression, where variables of age, sex, tumor size (>10 cm vs. ≤10 cm), tumor number (single vs. multiple), extrahepatic metastasis, macrovascular invasion or regional lymph node involvement, platelet count (>100 × 103/μL vs. ≤100 × 103/μL), Child–Pugh score, AFP, and PIKVA-II were entered.
