CHAPTER 2<br />

Tumours of the Urinary System<br />

With approximately 260,000 new cases per year worldwide,<br />

tumours of the urinary system contribute significantly to the<br />

overall human cancer burden. Progress in the early detection<br />

and treatment of bladder cancer has improved the prognosis,<br />

with five-year survival rates of 60 - 80%.<br />

The origin of bladder cancer is multifactorial, with tobacco<br />

smoking as the principal cause in most countries. Other etiological<br />

factors include analgesic abuse, occupational exposure<br />

and chronic Schistosoma cystitis.<br />

Urothelial carcinomas are the most frequent and important<br />

tumour type. Improvements in early detection have made<br />

reproducible grading and staging important criteria for clinical<br />

management and prognosis.
