immunotherapy
Cancer treatment that harnesses the patient's immune system to recognize and attack cancer cells.
Full Definition
Immunotherapy represents a revolutionary approach in urologic oncology that works by enhancing or restoring the body's natural immune response against cancer cells. In urologic cancers, immunotherapy includes checkpoint inhibitors (such as PD-1 and PD-L1 inhibitors), intravesical BCG for bladder cancer, and various investigational approaches. These treatments have shown particular promise in advanced kidney cancer and bladder cancer, often providing durable responses in patients who previously had limited treatment options. Unlike traditional chemotherapy, immunotherapy can cause unique side effects called immune-related adverse events.
