[Local care and systemic drug treatment of non-muscle invasive bladder tumors].

Bladder cancer is the most common malignancy of the urinary tract. It can be divided into non-muscle invasive and muscle-invasive groups according to depth of tumor invasion. Based on the significant differences regarding their biological behavior, propensity to progress, and therapy responsiveness these two groups are discussed seperately. Treatment of non-muscle invasive bladder cancers has traditionally been performed by urologists, but recent advances in the field predict that clinical oncologists may have a more intense role in high-risk non-muscle invasive cases. In the present study, we summarize the current surgical and pharmacological treatment options for non-muscle invasive bladder cancer.
