With low-grade bladder cancer, the recurrence rate is approximately 40-50% if no measures such as perfusion chemotherapy are administered. With effective bladder perfusion chemotherapy, the recurrence rate can be controlled at approximately 10-15%, but it also needs to be evaluated based on a combination of factors such as the size, extent, and degree of invasion of the patient’s tumor. If the tumor has invaded the bladder muscle, the recurrence rate can be significantly increased and will not decrease significantly even after bladder perfusion chemotherapy, and further total cystectomy is needed to prevent future tumor recurrence. If the tumor is single or invades only the submucosal layer, the recurrence rate is relatively low and can be significantly reduced after effective bladder irrigation chemotherapy. When bladder cancer is diagnosed, lifelong follow-up is needed, including regular cystoscopy and ultrasound examination of the urinary system, to detect recurrent lesions early and take effective interventions to avoid further increase in size or grade of the recurrent tumor, which may lead to a significant decrease in the patient’s survival quality and survival period.
