Gallbladder cancer Tis/T1a, belonging to carcinoma in situ, is also a stage of gallbladder cancer, indicating that gallbladder cancer has already invaded into the lamina propria of gallbladder mucosa, and according to gallbladder cancer diagnosis and treatment guideline, the survival rate of this kind of patients in 5 years after regular treatment is about 64%~86%. Tis/T1a of gallbladder cancer indicates that the cancer cells have begun to invade into the mucosa of gallbladder, but have not exceeded the mucosa of gallbladder and have not reached the muscular layer of gallbladder, which indicates that the onset of the disease is relatively early, and the prognosis is relatively good, and the survival rate within 5 years can reach 64%~86% through timely surgical resection, but it should be analyzed according to the progress of the disease and the results obtained after treatment. At present, gallbladder cancer Tis/T1a can choose to undergo simple cholecystectomy, and then regular observation and follow up on time after surgery. Generally, it is recommended to review every 3 months at intervals of 3 years, every 6 months at around 2-5 years, and every 12 months at intervals of 12 years if the survival period reaches more than 5 years. At present, gallbladder cancer Tis/T1a is found relatively early, so it needs to be treated early, which can prolong the survival period of patients and improve the quality of life, patients should have confidence in the condition during the treatment, and should not be overly into the fear.
