Invasive uroepithelial carcinoma with squamous differentiation, mainly bladder cancer, is the most common, and its treatment can adopt transurethral bladder tumor electrocision, radical cystectomy and other treatment methods according to the different depth of tumor infiltration and differentiation. 1. If the tumor belongs to Tis, Ta, T1, i.e. carcinoma in situ, tumor invades subepithelial connective tissue; transurethral cystectomy can be used. However, it should be noted that chemotherapeutic drugs should be instilled immediately within 24 hours after surgery, and chemotherapy in the bladder should also be maintained for patients at intermediate and high risk; the drugs include mitomycin, epirubicin, and so on. 2. For patients with T2~T4 stage bladder cancer, i.e. the depth of tumor infiltration has exceeded the muscularis propria, or there are distant metastases, radical cystectomy should be performed. For those who are in poor health and cannot tolerate this surgery, comprehensive treatment with bladder preservation can be considered. For metastatic bladder cancer that cannot be cured by surgery, the first choice of treatment is systemic chemotherapy. Specific treatment methods should be determined after going to regular hospitals for medical consultation, and medication should be prescribed by doctors.
