Predictive Values of Child-Pugh Score and Albumin-bilirubin Score for Liver Injury and Prognosis After Stereotactic Ablative Radiotherapy in Patients With Hepatocellular Carcinoma / 胃肠病学

ABSTRACT

Background:Child-Pugh score(CPS)and albumin-bilirubin(ALBI)score have important predictive value for the assessment of survival of patients with hepatocellular carcinoma(HCC). Aims:To investigate the predictive values of CPS and ALBI score for radiation-induced liver disease(RILD)and long-term prognosis in patients with HCC receiving stereotactic ablative radiotherapy(SABR). Methods:A total of 152 HCC patients receiving SABR from June 2006 to June 2012 at Baoji Central Hospital were enrolled. CPS and ALBI score were determined,and the predictive values of CPS and ALBI score for RILD and prognosis were compared. Results:In 152 patients with HCC,CPS-A was noted in 119 patients, CPS-B in 33 patients;ALBI-1 was noted in 60 patients,ALBI-2 in 86 patients,ALBI-3 in 6 patients. The 5-year overall survival rate was significantly higher in CPS-A patients than in CPS-B patients(46.2% vs. 15.2%,P <0.001). Significant difference in 5-year overall survival rate was found among patients with ALBI-1,ALBI-2 and ALBI-3(P =0.002). CPS grade(HR=1.38,95% CI:1.18-1.94,P=0.008)and ALBI grade(HR=1.68,95% CI:1.32-2.03, P=0.003)were independent risk factors for 5-year survival of patients with HCC. RILD was found in 20 cases(13.8%) within 4 months after SABR. AUC of ALBI for prediction of RILD was significantly higher than that of CPS(0.784 vs. 0.611,P=0.028). Patients with CPS-A and ALBI< -2.76 were less likely to develop RILD after SABR(2.4%). Conclusions:ALBI can effectively predict the occurrence of RILD and long-term survival of HCC patients after SABR.
