About Bladder Cancer
Bladder cancer ranks as the sixth most common cancer worldwide with 1 650 000 prevalent cases (5-year prevalence rate), 550 000 new cases and almost 200 000 deaths annually in 2018.1
Approx. 75% of all bladder cancer cases occur in men.1 It has a high recurrence rate with an average of 61% in year one and 78% over five years.2 Bladder cancer has the highest lifetime treatment costs per patient of all cancers.3
Bladder cancer is a costly, potentially progressive disease for which patients have to undergo multiple cystoscopies due to the high risk of recurrence. There is an urgent need to improve both the diagnosis and the management of bladder cancer for the benefit of patients and healthcare systems alike.
Bladder cancer is classified into two types, non-muscle invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer (MIBC), depending on the depth of invasion in the bladder wall. NMIBC remains in the inner layer of cells lining the bladder. These cancers are the most common (75%) of all BC cases and include the subtypes Ta, carcinoma in situ (CIS) and T1 lesions. In MIBC the cancer has grown into deeper layers of the bladder wall. These cancers, including subtypes T2, T3 and T4, are more likely to spread and are harder to treat.4
