Abstract: The present invention relates to the use of Chromogranin A (CgA) as a marker (particularly a prognostic marker) for bladder cancer, particularly non-neuroendocrine bladder cancer and preferably urothelial carcinoma. In particular, CgA can be used as a marker in an in vitro assay for the prognosis, risk assessment, risk stratification, monitoring and/or therapy control of bladder cancer (particularly non-neuroendocrine bladder cancer, preferably urothelial carcinoma). The invention further pertains to a method for the prognosis, risk assessment, risk stratification, monitoring and/or therapy control of bladder cancer (particularly non-neuroendocrine bladder cancer, preferably urothelial carcinoma) in a subject, comprising the step of determining the level of CgA and optionally MMP7 in a sample of a bodily fluid of said subject.
