There is no accurate clinical data to show how many years the survival period of bladder cancer is after surgery. Generally speaking, the survival time of patients after treatment needs to be judged by combining the actual condition of patients and their follow-up treatment. The prognosis of bladder cancer is closely related to factors such as tumor grading, staging, tumor size, recurrence time and frequency, number of tumors and the presence of carcinoma in situ. Bladder cancer is a relatively common malignant tumor in clinical practice, and the exact cause of the disease is still unclear. At the same time, there is no accurate clinical data to show how many years the survival period of bladder cancer is after surgery, and the survival time of patients after surgery is usually judged by 5-year survival rate, which varies according to the actual condition of patients. As the tumor of T1 stage bladder cancer is only confined to the mucous membrane layer of bladder, the 5-year survival rate of patients after surgery is higher, while the 5-year survival rate of T2 stage patients is relatively lower. While T3 and T4 stage bladder cancers have higher malignancy as the tumor has invaded the fat, tissues or organs around the bladder, and the 5-year survival rate after surgery is lower. Meanwhile, if the patient’s cancer cells have metastasized and spread, the chance of postoperative recurrence is higher, which will also have an impact on the 5-year survival rate. Usually, the 5-year survival rate of invasive bladder cancer patients who undergo bladder preservation surgery is 58.5%~69%, the 3-year survival rate of T2 stage is 61.2%, and the 3-year survival rate of T3 stage is 49.1%. Although it is impossible to accurately determine the survival period after bladder cancer surgery, patients are still recommended to seek medical treatment as early as possible and follow up regularly as prescribed by doctors.
