Summary
This phase II trial studies the benefit of adding an immunotherapy drug called MEDI4736 (durvalumab) to standard chemotherapy and radiation therapy in treating bladder cancer which has spread to the lymph nodes. Drugs used in standard chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Immunotherapy with durvalumab may help the body’s immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Giving chemotherapy and radiation therapy with the addition of durvalumab may work better in helping tumors respond to treatment compared to chemotherapy and radiation therapy alone. Patients with limited regional lymph node involvement may benefit from attempt at bladder preservation, and use of immunotherapy and systemic chemotherapy.
