Cytology correctly identified 93 out of 144 samples as positive for bladder cancer (sensitivity = 64.6%, 95% CI = 56.6% to 72.6%), whereas the AURKA FISH test, using the same cut point for positivity of the test (ie, >20% of cells with abnormal AURKA gene copy number) correctly identified 132 samples as positive for bladder cancer (sensitivity = 91.7%, 95% CI = 87.1% to 96.3%) (Fig. 5i). The gene discussed is AURKA; the disease is urinary bladder carcinoma.
