The patients were classified into three groups according to their change in serum AFP levels:(1) the normal group, pre-AFP ≤ 20 ng/m L and post-AFP ≤ 20 ng/m L;(2) the response group, pre-AFP > 20 ng/m L and post-AFP decrease of ≥ 50% of pre-AFP; and(3) the non-response group, pre-AFP level > 20 ng/m L and post-AFP decrease of < 50% or higher than pre-AFP level, or any pre-AFP level < 20 ng/m L but post-AFP >20 ng/m L RESULTS Univariate and multivariate analyses revealed thatmultiple tumors [hazard ratio(HR): 1.646, 95%CI: 1.15-2.35, P < 0.05], microvascular invasion(m VI)(HR: 1.573, 95%CI: 1.05-2.35, P < 0.05), and the nonresponse group(HR: 2.425, 95% CI: 1.42-4.13, P < 0.05) were significant independent risk factors for recurrencefree survival. Similarly, multiple tumors(HR: 1.99, 95%CI: 1.12-3.52, P < 0.05), m VI(HR: 3.24, 95%CI: 1.77-5.90, P < 0.05), and the non-response group(HR: 3.62, 95%CI: 1.59-8.21, P < 0.05) were also significant independent risk factors for overall survival. The nonresponse group had significantly lower overall survival rates and recurrence-free survival rates than both the normal group and the response group(P < 0.05). Thus, patients with no response regarding post-surgery AFP levels were associated with poor outcomes.CONCLUSION Serum AFP responses are significant prognostic factors for the surgical outcomes of HCC patients, suggesting post-resection AFP levels can direct the management of HCC patients. 关 键 词：Risk factors PROGNOSIS ALPHA-FETOPROTEIN HEPATOCELLULAR carcinoma Liver NEOPLASMS
