Following definitive therapy for muscle invasive bladder cancer, patients remain at risk for local and distant recurrence. Additionally, recurrences can result from formation of new tumours elsewhere in the urinary tract. We review patterns of recurrence and the prognosis associated with recurrence. Optimal surveillance strategies are discussed.

Metastatic or unresectable disease is identified in approximately 20% of patients presenting with invasive urothelial cancer. In addition, up to 50% of patients will develop metastases following radical cystectomy for clinically localized disease. Multiagent cisplatin-based chemotherapy is considered standard first-line treatment for these patients. Although urothelial cancer is considered a ...
Black, Peter - - 2009
Considerable debate exists concerning the combined use of systemic chemotherapy and radical surgery for muscle-invasive bladder cancer. While there is evidence for a survival benefit after neoadjuvant chemotherapy, the benefit is modest and the potential toxicity and delay of time to surgery prior to cystectomy appears to be deterring many ...
Kanaroglou, Androniki - - 2009
The standard of care in the management of invasive urothelial cancer of the bladder is radical cystectomy and pelvic lymphadenectomy. Although uncommon, recurrence of disease in the retained urethra following cystectomy carries a poor prognosis. The need for assessment of risk of recurrence is greater now than ever with wider ...
Yafi, Faysal - - 2009
Radical cystectomy with lymph node dissection remains the standard of care in the treatment of muscle-invasive and refractory non-invasive bladder cancer. Over the past decade, the extent of lymphadenectomy has varied to include dissection up to the common iliac vessels and aortic bifurcation proximally (may also extend up to the ...
Zlotta, Alexandre - - 2009
Up to 40% of patients with non-muscle-invasive bladder cancer (NMIBC) will fail intravesical bacillus Calmette-Guerin (BCG) therapy. There is unfortunately no current gold standard for salvage intravesical therapy after appropriate BCG treatment. Indeed, outcomes are at best suboptimal. The vast majority of low-grade NMIBC are prone to recur but very ...
Chalasani, Venu - - 2009
Bladder cancer can be classified histologically as urothelial or non-urothelial. Urothelial cancer has a propensity for divergent differentiation, which has increasingly been recognized in recent years due to heightened awareness and improved immunohistochemistry techniques. Furthermore, the recent World Health Organization classification of urothelial cancers improved clarity on this issue, with ...
Nepple, Kenneth - - 2009
Stage T1Hg bladder cancer should be considered an aggressive and potentially lethal disease. The importance of initial re-resection to identify unrecognized muscle-invasive disease is significant. Most patients with high-risk disease are candidates for initial bladder salvage with intravesical bacillus Calmette-Guerin vaccine for immunotherapy, a procedure with a high survival rate; ...
Lattouf, Jean-Baptiste - - 2009
Bladder cancer is the sixth most common tumour in Canada and ranks eighth in terms of cancer mortality. Up to now, management of this condition relied mostly on surgical and intravesical treatments once the disease is established. Chemoprevention is an attractive option to prevent the disease in high-risk populations and ...
Fradet, Yves - - 2009
Bladder cancer kills more women than cervical cancer and is also a significant cause of mortality in men. Little progress has been made in improving survival in patients with advanced bladder cancer. Two pilot studies using microhematuria screening have shown that screening for bladder cancer results in close to 80% ...
