Bladder cancer patients do not experience recurrence after total bladder excision surgery, but metastasis can occur because there is no longer a bladder in the body after total bladder excision, so there is no recurrence. Cancer cells may be present in the body’s bloodstream, and metastases from other parts of the body can occur under certain pathogenic conditions. Total cystectomy for bladder cancer is a kind of surgery to cure bladder cancer, and after resection, patients need to have long-term fistula, but all tumor blocks have been removed from the body, so it can be regarded as a clinical cure, but there may be latent oncogenes or cancer cells in the body, and metastatic foci of other parts of the body may appear again in the state of lowered immune system or other causative factors. At this time, treatment is still needed, and after the surgery, according to the results of local pathological examination and the results of margin cutting, it is necessary to decide whether it is necessary to carry out radiotherapy or chemotherapy to reduce the probability of metastasis after the surgery. However, the recurrence and metastasis rates of radical total cystectomy are low because it is a radical surgical method.
