N-Acetyltransferase Phenotypes in Bladder Tumour Patients with and without Carcinoma In situ in Selected Site Biopsies

Abstract

The N-acetyltransferase phenotypes were revealed among 32 patients with bladder tumour and concurrent carcinoma in situ peripherally in the bladder mucosa. Fifty-nine per cent of the bladder tumour patients with concurrent carcinoma in situ were slow acetylator phenotypes in contrast to 68% of 28 bladder tumour patients with normal histological specimens peripherally in the bladder mucosa. This points to a lack of industrial arylamine bladder tumour cases in Denmark.
