EurekAlert: The test cohort consisted of 2630 patients, of whom 55 (2.1%) had a neoplasm detected and 50 (1.9%) had a pathologically confirmed urinary tract cancer. The strongest predictors of cancer were age of 50 years or older and a recent diagnosis of gross hematuria. Male sex was also predictive of cancer, whereas smoking history and 25 or more red blood cells per high-power field on a recent urinalysis were not statistically significant. The findings were used to create a Hematuria Risk Index to predict cancer risk and performed comparably in the validation cohort of 1784 patients. Overall, 32% of the population was identified as low risk and 0.2% had a cancer detected; 14% of the population was identified as high risk, of whom 11.1% had a cancer found.
