Expression of maspin in papillary Ta/T1 bladder neoplasms.

Background: The aim of the present study was to evaluate maspin expression in bladder urothelial papillary neoplasms and test the results for correlation with clinicopathological parameters.

Patients And Methods: A total of 111 urothelial neoplasms from 66 patients were evaluated: pathological examination of primary tumours disclosed 48 pTa and 18pT1. Fourteen additional biopsies, negative for neoplasm, were collected as control biopsies.
