[Prognostic analysis of T1 and T2 stage gallbladder cancer with invasion within the gallbladder wall].

The prognosis of patients with T1 stage gallbladder cancer is much better than that of T2 stage. The 5-year survival rates of patients with T1a and T1b stage gallbladder cancer who received simple cholecystectomy are relatively good. Radical cholecystectomy and postoperative adjuvant chemotherapy can improve the prognosis of patients with T2 gallbladder cancer.
