ABSTRACT=<p><bold>Objective:</bold> The current study aimed to investigate the prognostic value of albumin-bilirubin (ALBI) score in predicting clinical outcomes of pancreatic cancer patients after pancreatoduodenectomy with liver metastasis following radiofrequency ablation.</p><p><bold>Methods:</bold> This retrospective study included 90 pancreatic cancer patients after pancreatoduodenectomy with liver metastasis from January 2012 to December 2018. In this study, the Chi-square or Fisher’s exact tests, the receiver operating characteristic (ROC) curve, Kaplan-Meier method and Log-rank test, univariate and multivariate Cox proportional hazard regression analyses, nomogram, calibration curves and decision curve analysis were used for all statistical analysis.</p><p><bold>Results:</bold> We analyzed the optimal cut-off value of ALBI by ROC curve, and the optimal cut-off value was −2.60. According to ALBI score, these patients were divided into two groups: low ALBI group (<italic>n</italic> = 33) and high ALBI group (<italic>n</italic> = 57). Patients with low ALBI score was significantly related to longer progression free survival (PFS) (<italic>p</italic> = 0.0002, HR: 3.039, 95% CI: 1.772–5.210) and overall survival (OS) (<italic>p</italic> = 0.0005, HR: 2.697, 95% CI: 1.539–4.720). The 1-, 3-, and 5-year PFS and OS rates in low ALBI group were higher than those in high ALBI group. ALBI was a potential independent prognostic factor for pancreatic cancer patients after pancreatoduodenectomy with liver metastasis following radiofrequency ablation. Moreover, the nomogram was used to predict the 1-, 3-, and 5-year survival probabilities of PFS and OS. The calibration curve shown that the prediction line matched the reference line well for postoperative 3-year PFS and OS. The DCA shown that nomogram model was better than the only ALBI, and indicated the ability for clinical decision-making, especially in 1-year PFS, and 3-, 5-year OS.</p><p><bold>Conclusion:</bold> ALBI is a potential independent factor for PFS and OS, and can predict the prognosis of pancreatic cancer patients after pancreatoduodenectomy with liver metastasis following radiofrequency ablation.</p>
