CIK in Treating Patients With Bladder Cancer

Chemotherapy is the main treatment method for patients with Bladder Cancer. However, Relapse remains the major cause of treatment failure.Biological therapies such as CIK stimulate the immune system and stop tumor cells from growing. A series of studies reported that cytokine-induced killer cells (CIK) have a broad anti-tumor spectrum. The investigators suppose that CIK will improve the prognosis. Combining chemotherapy with biological therapy may kill more tumor cells. In this study, the patients will be treated with CIK cells after chemotherapy. The purpose of this study is to evaluate the efficacy of CIK for Bladder Cancer.
