Figure 3. Effect of re-resection for pT2/3 incidental gallbladder cancer on survival outcomes. A: Comparison between those who underwent reresection and those who did not. The 5-year disease-specific survival rates were not significantly different (p=0.155). B: Comparison according to the presence of independent factors associated with a poor prognosis, namely grade 2 (G2) or poorer disease, or bile spillage at prior cholecystectomy. Survival of patients without any risk factor was significantly better (p=0.007). C: Comparison of patients who underwent reresection between those without any risk factor associated with a poor prognosis and those with one or two factors. The 5-year disease-specific survival rate was significantly better in those who had neither of the two independent factors associated with a poor prognosis (p=0.007).
