Simple cholecystectomy is an adequate treatment for grade I T1bN0M0 gallbladder carcinoma: Evidence from 528 patients

Figure 2 Overall survival and disease-specific survival of 528 patients with T1b gallbladder cancer who received different surgical treatment assessed using Kaplan-Meier analysis, and the proportions of different surgical approaches. A: Overall survival of patients with T1b gallbladder cancer (GBC) received simple cholecystectomy (SC), SC with lymph node resection (SC + LN), or radical cholecystectomy (RC) (P < 0.001); B: Disease-specific survival of patients with T1b GBC who received SC, SC + LN, or RC (P = 0.003); C: The proportions of different surgical approaches in patients with different pathological grades of gallbladder cancer. SC: Simple cholecystectomy; LN: Lymph node resection; RC: Radical cholecystectomy.
