Rational therapeutic strategy for T2 gallbladder carcinoma based on tumor spread

Figure 1 Kaplan-Meier survival analysis of patients with T2 gallbladder carcinoma by ss score. A: Disease-specific survival; the 5-year survival rate for ss min and ss med was 100%. In ss mas gallbladder carcinoma (GBCa), the 5-year survival rate was 59.7%; B: Disease-free survival; the 5-year survival rate for ss min and ss med was 100%. In ss mas GBCa, the 5-year survival rate was 56.6%.

Figure 2 Kaplan-Meier survival analysis by surgical procedure for T2 gallbladder carcinoma. BDR: With extra-hepatic BDR; BDR (-): Without extra-hepatic BDR; S4a5: S4a5 hepatectomy; Cx: Simple cholecystectomy; D2ex: D2 lymph node dissection with para-aortic lymph node sampling. BDR: Bile duct resection.
