Urachal Carcinoma of the Bladder: Impact of Clinical and Immunohistochemical Parameters on Prognosis

The independent prognostic value of a positive resection margin underlines the importance of complete surgical removal of urachal carcinoma of the bladder combined with en bloc resection of the median umbilical ligament and umbilicus. Our results in a limited number of samples show that Ki67, p53, RHAMM and IMP3 expression is enhanced but has no prognostic significance in urachal carcinoma of the bladder.
