Scoring criteria for determining the safety of liver resection for malignant liver tumors

Figure 1 Linear regression analysis of total liver volume and body surface area. Standard liver volume (mL) = 822.7 × BSA - 183.2; R² = 0.419, R = 0.644; P < 0.001.

Figure 2 Linear regression analysis of serum antithrombin III levels and the indocyanine green retention rate at 15 min. ATIII + 1.461 × ICGR15 = 108.068; R² = 0.151, R = 0389: P < 0.001. ATIII: Antithrombin III; ICGR15: Indocyanine green retention rate at 15 min.

Figure 3 The results of the linear regression analysis of the reduction in liver volume and the Sapporo score. A: Linear regression analysis of the reduction in liver volume and the Sapporo score; Closed circles: Grade IV and V postoperative liver failure/dysfunction Open circles: Complication-free cases; B: Relationships between the Sapporo score, resectable liver volume, and residual liver volume.
