Impact of obesity on the surgical outcome following repeat hepatic resection in Japanese patients with recurrent hepatocellular carcinoma

Figure 1 Comparison of the survival curves after a primary hepatectomy in the nonobese group (BMI < 25 kg/m², n = 240) versus the obese group (BMI ≥ 25 kg/m², n = 88). The patient’s survival rate in the nonobese group did not differ significantly from that in the obese group.

Figure 2 Comparison of the survival curves after primary hepatectomy in the nonobese group (BMI < 25 kg/m², n = 240) versus the obese group (BMI ≥ 25 kg/m², n = 88). No significant difference in the disease-free survival rate between the two groups was observed.

Figure 3 Comparison of the survival curves after repeat hepatectomy in the nonobese group (BMI < 25 kg/m², n = 44) versus the obese group (BMI ≥ 25 kg/m², n = 16). The patient’s survival rate in the obese group was significantly lower than that in the nonobese group (P < 0.05).

Figure 4 Comparison of the survival curves after a repeat hepatectomy in the nonobese group (BMI < 25 kg/m², n = 44) versus the obese group (BMI ≥ 25 kg/m², n = 16). A significantly shorter disease-free survival was found in the obese group than in the nonobese group (P < 0.05).
