Abstract

Background To evaluate the utility of the Johns Hopkins Hospital (JHH) template in detection of high-grade urothelial carcinoma (HGUC). Methods A computerized search of our laboratory information system was performed for all urine cytology cases from 2009 to 2011 processed by the SurePath™. We included only cases with correlating surgical pathology within 6 months after the urinary samples were obtained. The original cytologic diagnoses were reclassified according to the JHH template, and these cytolog ic diagnoses were then correlated with the follow-up surgical pathology diagnoses. Results A total of 273 urine samples with histopathologic follow-up were identified. The reclassified cytologic diagnoses included negative for urothelial atypia or malignancy (NUAM) 110; atypical urothelial cells of undetermined significance (AUC-US) 83; atypical urothelial cells, cannot exclude high-grade urothelial carcinoma (AUC-H) 49; HGUC 29; and low-grade urothelial carcinoma (LGUC) 2. More than one-half of patients (58%) who had biopsy-confirmed high-grade urothelial lesions had a preceding cytologic diagnosis of AUC-H or HGUC. AUC-H and HGUC are associated with high-grade urothelial lesions in 80% and 90% of the cases and show statistical significance when compared with AUC-US or NUAM (P < 0.05). Conclusion The JHH template is useful and effective in identifying patients with high-grade urothelial lesions who need to undergo cystoscopy. Diagn. Cytopathol. 2015;43:593-597.
