Background And Aims:
The ASAP score, which incorporates age, sex, alpha-fetoprotein (AFP), and protein induced by vitamin K absence-II, has demonstrated promise for early detection of hepatocellular carcinoma (HCC). However, its prognostic value after HCC treatment remains unknown. The current study sought to evaluate the prognostic value of the ASAP score to predict recurrence and survival following curative hepatic resection for HCC.
Methods:
This study using prospectively collected data included HCC patients who underwent curative-intent hepatic resection. The ASAP score was calculated preoperatively, and X-tile analysis was used to determine the optimal cutoff value. Univariate and multivariate analyses were performed to identify independent risk factors associated with recurrence and overall survival (OS).
Results:
Among 1239 patients in the analytic cohort, the optimal ASAP score cutoff was 4.8; patients were divided into low (n = 749) and high (n = 490) ASAP score subgroups. Patients with high ASAP scores had a higher incidence of 5-year recurrence (73.9% vs 51.0%, P < 0.001) and worse OS (31.7% vs 60.1%, P < 0.001) versus individuals with low scores. Multivariate analysis identified ASAP score ≥4.8 as an independent risk factor of both recurrence (hazard ratio [HR] 1.976, 95% confidence interval [CI]: 1.633-2.390, P < 0.001) and OS (HR 1.407, 95% CI 1.170-1.691, P < 0.001) after controlling for established clinicopathological factors.
Conclusion:
Preoperative ASAP score was independently associated with recurrence and survival after HCC resection. The clinical utility of the ASAP score may be applicable to both diagnosis and prognosis, potentially improving postoperative surveillance and management strategies for HCC patients.
