Bladder cancer is a common cancer of the urinary tract. It is the fourth leading cause of cancer-related death among men and the seventh among women. Clinical management of bladder cancer is challenging because of the heterogeneity among bladder tumors with respect to invasion and metastasis, frequent occurrence of new tumors in the bladder among patients treated with bladder preservation treatments and poor prognosis of patients with tumors that invade the bladder muscle and beyond. Due to these factors it has been said that the cost per patient of bladder cancer, from diagnosis to death is the highest of all cancers. In addition to it being a significant health problem, bladder cancer is an interesting cancer to study in many ways than one. For example, Environmental factors such as cigarette smoking and other carcinogens play a major role in the development of transitional carcinoma of the bladder, whereas, schitosomasis, a protozoan infection results in squamous cell carcinoma of the bladder. Different molecular pathways with distinct molecular signatures appear to be involved in the development of low-grade versus high-grade bladder tumors. Currently being monitored by an invasive endoscopic procedure, cystectomy, with urine cytology as an adjunct, bladder cancer is at the forefront of developing cancer biomarkers for non-invasive detection. Due to the differences in the invasive and metastatic potential of bladder tumors, treatment options differ depending upon tumor grade and stage. New advances are being made in treatment options to improve the outcome and quality of life for patients with bladder cancer. Similarly, new molecular nomograms are being discovered to predict treatment outcome so that individualized treatment options can be offered to patients.

Clinical management of bladder cancer is challenging of the heterogeneity among bladder tumors with respect to invasion and metastasis, and frequent occurrence of new tumors in the bladder among patients treated with bladder preservation treatments. Treatment of bladder cancer spans from tumor resection and intravesical treatment, to neoadjuvant chemotherapy, radical surgery and adjuvant chemotherapy. At the same time, bladder cancer is also at the forefront of biomarker development because of the ease of developing noninvasive urine tests. The features of environment-driven carcinogenesis and divergent molecular pathways in the development of low- and high-grade tumors provide a unique opportunity for advance molecular research in cancer biology. Bladder Tumors: Molecular Aspects and Clinical Management is a collection of comprehensive reviews on the state-of-the art basic science research and clinical management of bladder cancer. The book progresses from epidemiology of bladder cancer, molecular basis of bladder carcinogenesis, to standard and molecular aspects of bladder cancer diagnosis and prognosis, and also includes various treatment aspects of both non muscle invasive and muscle invasive bladder cancer. The book features: * Epidemiology, bladder carcinogenesis and divergent molecular pathways of bladder cancer development. * Pathology of bladder tumors, cystoscopy, cytology and newer techniques of bladder cancer diagnosis. * Molecular basis, efficacy and economics of diagnostic and prognostic markers for bladder cancer, with an added feature of recent inventions of molecular nomongrams. * Clinical management of low-grade and non muscle invasive bladder tumors. * Intravesical chemotherapy versus immune (BCG) therapy. * Clinical management of patients with muscle invasive bladder cancer, including neoadjuvant therapy, various aspects of cystectomy including urinary diversion and recent advances such as laproscopic cystectomy * Ad
