Postoperative outcomes and recurrence patterns of intermediate-stage hepatocellular carcinoma dictated by the sum of tumor size and number

Figure 1 The receiver operating characteristic analysis of the sum of tumor size and number, the classification of the sum of tumor size and number, tumor burden score and total tumor volume in intermediate-stage hepatocellular carcinoma patients. A: 3-year overall survival (OS); B: 5-year OS. N + S: The sum of tumor size and number; TBS: Tumor burden score; TTV: Total tumor volume; AUC: Area under receiver operating characteristic curve.
