Association Between Urinary Cytology and Pathology for Nontransitional Cell Malignancies of the Urinary Tract
Neoplasm Recurrence, Local
Urinary Bladder Neoplasms
In our series all patients with nontransitional cell carcinoma cytological results had cancer in the urinary tract. Thus, nontransitional cell carcinoma cytology findings mandate careful urinary tract evaluation. Concordance with histological subclassification on subsequent pathology evaluation ranges from 49% for squamous cell carcinoma to 86% for adenocarcinoma. A majority of patients with nontransitional cell carcinoma malignancies had positive prior cytology findings. However, the concordance with histological subclassification on prior cytology results ranges from 19% for adenocarcinoma to 60% for squamous cell carcinoma.
