The European Association of Urology Non-Muscle-Invasive Bladder Cancer (EAU NMIBC) risk calculator is specifically designed for patients diagnosed with non-muscle-invasive bladder cancer. The calculator uses the 1973 World Health Organization grading system to stratify patients into risk groups based on various factors such as tumor size, number of tumors, prior recurrence rate, and presence of carcinoma in situ.
The clinical utility of the EAU NMIBC risk calculator is to predict the likelihood of recurrence and progression of non-muscle-invasive bladder cancer. This can help clinicians in making informed decisions about the management and treatment of the disease, including the need for more aggressive treatment or closer surveillance.
Exclusion criteria for the use of this calculator would include patients with muscle-invasive bladder cancer, those who have not had a confirmed diagnosis of bladder cancer, or those with insufficient data to complete the risk assessment.
