• W2891484828 abstract "e15622 Background: Many HCC patients are diagnosed as locally advanced and loco-regional therapies improved the prognosis of these patients. Survival rates of these patients vary differently. We want to research on the prognostic factors and establish a new prognostic model based on total tumor volume(TTV) to predict the survival rate in locally advanced hepatocellular carcinoma patients who receive loco-regional therapy. Methods: 214 locally advanced HCC patients who received TACE or PEJ were retrospectively studied. Univariate and multivariate analyses were used to assess the variables. A new prognostic model based on TTV was developed with independent prognostic factors. The predictive value was evaluated using receiver operator characteristic curve (ROC) analyses. Results: The median survival is 23.4 months. Univariate and multivariate analyses showed that total tumor volume (TTV), child-pugh garde, protal vein thrombosis and antivirus therapy were independent factors of overall survival. A risk model was establsihed and it is consisted of 4 factors mentioned above. 214 patients were classified into 5 stages by the new staging system. We researched on the predictive value of the new prognostic system by comparing it with CLIP, BCLC and TNM. When predicting 1-year OS, AUC of the new prognostic system, CLIP, BCLC and TNM is 0.620, 0.735, 0.527 and 0.655, respectively; CLIP is best when predicting 1-year os. When predicting 2-year OS, AUC of the new prognostic system, CLIP, BCLC and TNM is 0.623, 0.671, 0.516 and 0.577, respectively;The new prognostic system is as good as CLIP. When predicting 3-year OS, AUC of the new prognostic system, CLIP, BCLC and TNM is 0.623, 0.645, 0.504 and 0.593, respectively; The new prognostic system is as good as CLIP and is better than BCLC(P < 0.05). Conclusions: Total tumor volume is independent prognotic factors of locally advanced hepatocellular carcinoma patients who received locoregional therapies.The new prognostic system based on TTV is as good as CLIP in predicting 2-year OS and 3-year OS. A new prognostic system based on TTV TTV(CM3) < 22.5(0) ≥22.5(1) Antivirus therapy No(0) Yes(1) Child pugh Grade A(0) B(1) Portal vein thrombosis No(0) Yes(1)" @default.
