[Value of systemic chemotherapy in bladder cancer].
Almost half of the patients with muscle invasive disease already harbor at the time of their first diagnosis occult or distant metastases. Systemic disease has a poor prognosis with a long term survival of less than 10%. The administration of systemic chemotherapy aims to improve the course of locally advanced or metastatic disease.A survival benefit of 5% for patients receiving neoadjuvant and 9-11% using adjuvant chemotherapy is in the first scenario minimal, in the adjuvant setting to be noteworthy. The MVAC-schedule and the Gemcitabine/Cisplatin-combination chemotherapy have to be regarded as standard for induction chemotherapy. However, the 5-year survival rates with 15 or 13% are disappointing.Thus, prognostic factors gain importance since with their consideration significant differences in survival rates can be found. Hope is provided by a novel class of substances, the target-specific drugs, which selectively interfere with the cascade of steps involved in tumorigenesis.
