Abstract

INTRODUCTION: Although preoperative alpha-fetoprotein (AFP) has been recognized as an important tumor marker among patients with hepatocellular carcinoma (HCC), the predictive value of AFP levels at the time of recurrence (rAFP) on post-recurrence outcomes has not been well examined.METHODS: Patients undergoing curative-intent resection of HCC between 2000 and 2017 were identified using a multi-institutional database. The impact of rAFP on post-recurrence survival, as well as the impact of rAFP relative to the timing and treatment of HCCrecurrence wereexamined.RESULTS: Among 852 patients who underwent resection of HCC, 307 (36.0%) individuals developed a recurrence. The median rAFP level was 8ng/mL (interquartile range 3-100). Among the 307 patients who developed recurrence, 3-year post-recurrence survival was 48.5%. Patients with rAFP>10ng/mL had worse 3-year post-recurrence survival compared with individuals with rAFP<10ng/mL (28.7% vs. 65.5%, p<0.001). rAFP correlated with survival among patients who had early (3-year survival; rAFP>10 vs. <10ng/mL: 30.1% vs. 60.2%, p<0.001) or late (18.0% vs. 78.7%, p=0.03) recurrence. Furthermore, rAFP levels predicted 3-year post-recurrence survival among patients independent of the therapeutic modality used to treat the recurrent HCC (rAFP>10 vs.<10ng/mL; ablation: 41.1% vs. 76.0%; intra-arterial therapy: 12.9% vs. 46.1%; resection: 37.5% vs. 100%; salvage transplantation: 60% vs. 100%; all p<0.05). After adjusting for competing risk factors, patients with rAFP>10ng/mL had a twofold higher hazard of death in the post-recurrence setting (hazard ratio 1.96, 95% confidence interval 1.26-3.04).CONCLUSION: AFP levels at the time of recurrence following resection of HCC predicted post-recurrence survival independent of the secondary treatment modality used. Evaluating AFP levels at the time of recurrence can help inform post-recurrence risk stratification of patients with recurrent HCC.
