Objective To evaluate the modified Barcelona Clinic Liver Cancer (BCLC) staging system for predictability of intrahepatic recurrence for patients with hepatocellular carcinoma (HCC) following curative hepatectomy.Methods A retrospective study was conducted on 197 consecutive patients with HCC who underwent curative hepatectomy in our department from Jan.2008 to Jan.2011.Univariate and multivariate analyses using Cox proportional hazard model were used to evaluate possible association between clinicopathologic factors and early postoperative intrahepatic recurrence (ER).Receiver operating characteristics (ROC) analysis with calculation of the area under the curve (AUC),sensitivity,and specificity were applied to define the cutoff point values for possible meaningful continuous variables where appropriate.A comparison between the differences in AUC was used to assess BCLC and a modified BCLC (M-BCLC) staging system for their predictive ability of ER.Risk stratification according to calculated M-BCLC was applied to find differences of ER at various time points after curative hepatectomy.Results During follow-up,111 patients developed ER.The 6-,9-,12-,18- and 24-month cumulative recurrent rates were 26.9％ (53/197),37.6％ (74/197),45.2％(89/197),53.8％ (106/197) and 56.3％ (111/197),respectively.Multivariate analysis revealed thatthe severity of concomitant cirrhosis,elevated AFP≥185.6 μg/L and BCLC staging were risk factors of ER.A M-BCLC was proposed based on the results of multivariate analysis.The severity of cirrhosis and elevated AFP values were included in the BCLC staging.This M-BCLC exhibited better performance.It predicted at different time points of ER at postoperative 9,12,18 and 24 months to be significantly better with M-BCLC than BCLC using AUC drawn from ROC.No significant difference was found with ER prediction at 6 months.The M-BCLC also demonstrated a ER prediction with AUC of 0.710 (95％ CI,0.630-0.790) and achieved a sensitivity of 83.0％,a specificity of 51.9％as calculated from ROC with M-BCLC≥2.913.Further risk stratification according to the M-BCLC at various cutoff point values revealed the ER occurrence rates amongst the different risk groups to be significantly different when compared with the median ER time (17.9 mons,9.9 mons vs 5.7 mons,x2=25.770,P=0.000,Log-Rank test).Conclusion A modified BCLC staging system based on multivariate analysis improved the predictability of ER following curative hepatectomy for HCC.
