After our successful first Special Issue about bladder cancer, we proceeded with the second issue. Again, many international scientists submitted their newest research results in that extremely interesting field and followed our call for submissions. It is not only the collection and combination of old and new markers that could develop new possibilities, but also the focus on different classifications and sub-classifications that will unveil new ways in diagnostic and therapeutic approaches. It seems that the two established diagnostic tools will still play an important role, but new markers and diagnostics tools will present more detailed and more differentiated possibilities in the treatment of urinary bladder cancer. This second Special Issue is full of scientific results that could provide new ways to help patients with instruments for early diagnostics and with predictive and prognostic markers on their way to finding new and personalized strategies for therapy. The editors thank all of the submitting authors for their efforts and time spent on each manuscript. We hope that this Special Issue will prove useful to research work in bladder cancer in the future. We hope that many talented researchers will use multiple forms of art to improve their professional successes and to ameliorate diagnostics and therapy in bladder cancer.

This book is a printed edition of the Special Issue 2Diagnostic, Prognostic and Predictive Biological Markers in Bladder Cancer – Illumination of a Vision" that was published in IJMS

This Special Issue has been introduced with the aim of offering the possibility to publish new research results from old and new pioneers in the field of bladder cancer basic research. While editing this Special Issue we learned that an enormous enthusiasm is necessary to go on in bladder cancer research. In our eyes, bladder cancer is on one hand a very heterogenous malignancy, which is what makes it so difficult to focus on only one bladder cancer marker in bladder cancer diagnostics and follow-up. On the other hand, it is very important to find prognostic and predictive factors for bladder cancer due to its high incidence and its enormous costs, as one of the most expensive malignancies in the world. Finding and developing new bladder cancer markers is still a very dynamic field. Because there are many of these markers, it is impossible to report all of them. This Special Issue attempts to highlight the role of bladder cancer markers in diagnosis, and the most important biomarkers that have been recently studied and reported. This Special Issue highlights some of the most important markers. Further determination of recurrence and progression markers will contribute to establishing better treatments for individual patients. Molecular staging of urological tumors will allow the selection of cases that will require systemic treatment. It is necessary and important to integrate basic and clinical research under the same objectives.
