Preoperative predictors of short-term survival after hepatectomy for multinodular hepatocellular carcinoma

Figure 1 Distribution of tumor size according to tumor differentiation and presence of microvascular invasion, showing median, 25th-75th percentile box and complete range of measurements. A: Distribution of total tumor size according to tumor differentiation (P = 0.003); B: Distribution of total tumor size according to presence of microvascular invasion (P < 0.001); C: Distribution of the largest tumor size according to tumor differentiation (P = 0.008); D: Distribution of total tumor size according to tumor differentiation and presence of microvascular invasion (P < 0.001). The tumor size was associated with presence of microvascular invasion and poor tumor differentiation. MVI: Microvascular invasion.

Figure 2 Receiver operating characteristics curve of the predictive scoring system. The area under the curve was 0.925, 95% confidence interval was 0.864-0.985 (P < 0.001). The data indicated that the scoring system had a strong ability to predict the 1-year outcome of patients with multiple hepatocellular carcinoma after hepatic resection.

Figure 3 Results of long-term survival of group 1 (score < 5) and group 2 (score ≥ 5). The overall survival and disease-free survival in group 2 were significant poorer than those in group 1 (both P < 0.001).
