• 1. Epidemiology of Bladder CancerBladder cancer is a "carcinogen-driven" cancer. Cigarette smoking, exposure to arylamines have been linked to increased risk for developing bladder cancer. Some other causes, arsenic exposure, hair dressers/hair dyes, etc. Another cause of bladder cancer of a separate type is bilharzial disease/schistosomiasis. Topics to be covered: Bladder cancer incidence and prevalence world wide, US and Africa (Bilharzial disease).Bladder carcinogens and their correlation to bladder cancer incidence. Field effect theory and is it supported by molecular characterization of recurrent tumors (i.e., is this a recurrence or a new tumor). Bilharzial disease and bladder cancer in Egypt: any molecular link?Include both EU and USA guidelines.Possible author: Maria Ribal from Barcelona2. Molecular Signatures of Bladder CancerBladder tumors have two characteristics: Heterogeneity in invasion and metastasis and frequent recurrence. Studies on molecular determinants of bladder cancer have discovered that low- and high-grade tumors may develop through divergent molecular pathways. However, current molecular signatures do overlap. Part of the reason for this overlap may be some low-grade patients develop high-grade tumors. Topics to be covered: Divergent pathways for the development of low-grade and high-grade tumors. Molecular signatures characteristics of these divergent pathways (FGF-mutations, Ki67, p53 mutations). How definitive are these signatures for predicting the development of low-grade versus high-grade tumors. Development of carcinoma in situ. What are the possible causes of overlap between these divergent pathways. recurrent versus.Possible authors: Ashraf Bakkar, Dr. Droller.3.

Bladder cancer diagnosis and detection – Current Status (cystoscopy, upper track imaging): Current mode of bladder cancer detection, AUA guidelines for detecting bladder cancer, cystoscopy, a brief reference to cytology without going into details. Topics to be included: Diagnosis and Staging of bladder cancer; The role of imaging; MRI/CT for local staging of bladder cancer; Imaging of lymph node involvement; Distant metastasesPossible authors: Prof. Richard Sylvester from Brussels or Fred Witjes from Nijmengen Netherlands.5. Urine Cytology, DNA Ploidy and current approaches: Value of cytology as an adjunct to cystoscopy. Why it is still preferred despite new cell-based bladder tumor markers.Possible authors: Dr. Murphy + Eva Wojcik 6. Bladder tumor marker (Urine markers for bladder cancer diagnosis): Currently, the detection of primary and recurrent tumors is based on urine cytology and cystoscopy. With the high rate of recurrence, cystoscopies are regularly repeated with the aim of halting progression of the disease. For patients, this process is fraught with anxiety, pain and high cost. Therefore, intense work is being done to bring accurate bladder tumor markers into clinic for both the initial diagnosis and detection of tumor recurrence. The possibility of identifying a marker that could non-invasively differentiate benign and malignant causes of hematuria, and identify recurrences prior to their clinical manifestation is the objective of this area of research. In addition, due to the ease of obtaining voided urine specimens, bladder cancer is at the forefront of developing cancer diagnostic tests. In this review we will discuss many of the widely used or tested markers, along with some novel modalities. Background details will be provided as to themechanism of detection of malignant cells, the results of recent trials, and future directions of study. The next few years will no doubt bring newer markers and perhaps the elimination of others. Studies continue to refine the role of these markers in clinical practice but their ultimate efficacy will need to be borne out in large-scale clinical trials in a multitude of settings. Confirmed authors: Shirodkar and Lokeshwar7. Economics of bladder cancer diagnosis and surviellance: Cystoscopy is still the gold standard for both detection and surveillance of bladder cancer. Because of the cost involved in surveillance, and the treatment of recurrent tumors bladder cancer is one of the costliest cancer to treat. Several studies on cost analyses have shown that bladder tumor markers may prove to be cost effective however patients are reluctant to forgo cystoscopy. Thus, a discussion of cost versus benefits of both cystoscopy and bladder tumor markers will be helpful, given the number of bladder tumor markers currently in the market and more coming down the pike. Topics to be covered: Comparison of bladder cancer diagnosis in terms of cost and of tumor markers and analyses of cost versus benefits.

Prognostic Markers for bladder cancer:Prognostic markers for bladder cancer are needed for monitoring treatment response after TURBT, TURBT+ intravesical therapy or cystectomy. Monitoring of treatment response is required for predicting recurrence, disease progression (from non-muscle invasive disease to muscle invasive disease, or from muscle invasive bladder cancer to metastasis) and survival. Several prognostic markers have been studied. Possible topics: markers in various cellular categories (cell surface, proliferation antigens, growth factors/growth factor receptors, nuclear antigens/transcription factors) with emphasis on p53, Ki67, pRb.Possible authors: Fred Witjes from Nijmegen, The Netherlands + Habuchi, Japan8. Molecular Nomograms for predicting prognosis and treatment response:Recent investigations have shown that instead of single markers, molecular analysis of tumor tissues may allow better prediction of prognosis. Some of these advances include COXEN analyses, Forerunner genes. Topics to be included: cDNA microarray, microRNA, COXEN.Possible author: Dan Theoderescu, University of Virginia, VA9.

Cystectomy for non-muscle invasivebladder cancer Patients with pT1 G3 bladder tumors are at high risk of tumour progression and death from disease. Induction and maintenance of intravesical BCG treatment has proven to reduce tumour progression in non muscle invasive bladder cancer at moderate risk of progression. However, recent data on survival and new developments in molecular markers and nomogramms predicting the clinical course of the disease often predict the then observed clinical scenario. Therefore some surgeons support an early radical surgical approach even in non muscle invasive disease classified as pT1, G3 or with a high risk profile (multiple tumours, tumour size, CIS, early recurrences, etc.). The pro- and con- for radical surgery should be discussed as well as an overview on the available published literature.Confirmed authors: Axel Merseburger and Markus Kuczyk14. Radical surgery Indications: Radical cystectomy is the standard treatment for localized muscle invasive bladder cancer in most countries. There is still controversy about age, radical cystectomy and the type of urinary diversion. Cystectomy is associated with the greatest risk reduction in disease-related and non-disease related death in patients olderthan 80 years. Traditionally radical cystectomy is recommended for patients with muscle-invasive bladder cancer T2-T4a, N0-Nx, M0, as well as extensive papillary disease that cannot be controlled with TUR and intravesical therapy alone.Optimal timing and delay of cystectomy: In a retrospective series of 153 patients with a clear indication for radical surgery of locally advanced bladder cancer, a delay of treatment beyond 90 days of primary diagnosis caused a significant increase in extravesical disease (81 vs. 52%)Technique and extent: Radical cystectomy includes the removal of the bladder and adjacent organs, that is prostate and seminal vesicles in men, and uterus and adnexa in women. Radical cystectomy also includes the dissection of regional lymph nodes. There is a substantial amount of literature about the extent of lymphadenectomy. Yet, data regarding its clinical significance are controversial. Laparoscopic cystectomy has been shown to be feasible both in male and female patients.Arnulf Stenzl or e.g. Jürgen Geschwend, or Sudhir Rawal from India15. Urinary DiversionFrom an anatomical standpoint three alternatives are presently used after cystectomy: Abdominal diversion such as ureterocutaneostomy, ileal or colonic conduit, and various forms of a cutaneous continent pouch; Urethral diversion which includes various forms of gastrointestinal pouches attached to the urethra as a continent, orthotopic urinary diversion (neobladder, orthotopic bladder substitution; Rectosigmoid diversions, such as uretero(ileo-)rectostomy.Debilitating neurological and psychiatric illnesses, limited life expectancy, andimpaired liver or renal function as well as TCC of the urethral margin or other surgical margins are contraindications to more complex forms of urinary diversion.All used urinary diversions forms should be described with modern mortality and morbidity data. Aside a subchapter should cover the reachable disease-free and overall survival data.Confirmed: Stefan Hautmann; Richard Hautmann (possible co-author)16. Laparoscopic cystectomy: Decision open versus laparoscopic cystectomy (who are the best candidates), benefits and pitfalls, long term results (??). The cystectomy itself and the subsequent urinary diversion can be done hand-assisted, robot-assisted or unaided. With the currently available technology and when using intestinal segments for the urinary diversion, to date a majority of authors favour an extracorporeal approach. There are no data confirming or declining benefits of laparoscopic cystectomy for the patients’ quality of life, tumour specific and overallsurvival.Possible author: Indebir Singh Gill 17. Neoadjuvant chemotherapy: Neoadjuvant chemotherapy is given to improve the outcome of cystectomy. Current regimen includes cisplatin and gemcitabine combination. Advantages of neoadjuvant chemotherapy will be a pT0 disease at cystecomy, failure of the treatment can lead to disease progression. Topic to be covered: Who are the candidates for neoadjuvant chemotherapy, types of neoadjuvant chemotherapy (platins +/_ gemcitabine), outcome, failure, any molecular markers that predict response to neoadjuvant chemotherapy. Armir Sherif18. Bladder cancer treatment and quality of life issues:Patients undergoing bladder sparing treatment need to undergo frequent cystoscopy for surveillance, TURBT +/- intravesicle therapy for recurrent tumors. Patients with cystectomy and urinary diversion deal with an illeal conduit (and are at a risk for developing infections) or a neo-bladder. Thus, bladder cancer treatments pose certain quality of life issues for the patients and these may need to be considered when weighing benefits and cost of each treatment.
