What are the chemotherapy regimens for bladder cancer?

The chemotherapy regimens for bladder cancer mainly include three types: 1. Intravesical chemotherapy: This involves directly instilling high concentrations of anticancer drugs into the bladder, thereby acting directly on the bladder cancer and killing cancer cells. This method has minimal systemic toxicity, is convenient to administer, and better preserves the patient's physiological function. It is commonly used for the treatment of superficial bladder cancer or for preventing recurrence after bladder surgery. 2. Interventional chemotherapy: Chemotherapy drugs are delivered to the target tumor site through the blood vessels supplying the tumor. This method can increase drug concentration at the tumor site, enhancing treatment effectiveness, while reducing systemic toxic side effects. 3. Systemic chemotherapy: This is suitable for invasive bladder cancer and advanced cancer with existing metastases, or as adjuvant therapy after surgery and for postoperative recurrent cases. Chemotherapy regimens for bladder cancer should be determined according to the patient's specific condition and conducted under the guidance of a specialized physician.
