Bladder uroepithelial cancer is treated by choosing minimally invasive surgery, perfusion chemotherapy and radical treatment according to different stages and malignant degree. 1. Non-muscle invasive bladder cancer, i.e. the tumor only invades the bladder epithelial tissue without invading the muscle layer, and there are no lymph nodes and distant metastases. They usually receive a comprehensive treatment plan of surgical resection (usually transurethral resection of the tumor) combined with postoperative bladder instillation, and are risk stratified according to the number of tumors, size, and pathological grading to determine the course of bladder instillation regimen and whether radical resection is performed. 2. If the tumor invades the muscular layer of the bladder, it is muscle invasive bladder cancer (MIBC), and its treatment plan needs to comprehensively evaluate the specific stage of the tumor and the physical status of the patient: (1) Neoadjuvant chemotherapy combined with radical total cystectomy is the standard treatment option for MIBC patients. (2) For patients with locally progressive MIBC (usually with peripheral tissue/organ invasion but without distant metastasis), systemic systemic therapy combined with local therapy, such as systemic chemotherapy combined with surgical resection, systemic chemotherapy combined with local radiotherapy, etc., is the standard treatment option for patients with locally progressive MIBC. (3) For patients with metastatic MIBC (patients with distant metastases), systemic systemic therapy combined with supportive therapy, such as systemic chemotherapy, immunotherapy (PD-1 or PD-L1 inhibitors, etc.). If bladder tumor is suspected or diagnosed, it is recommended to go to a regular hospital for comprehensive evaluation of the condition, follow the doctor’s instructions to cooperate with the treatment, and choose the appropriate treatment plan to avoid delaying the condition. Please strictly follow the doctor’s instructions for medication, and do not use medication on your own.
