Grading of transitional cell tumours of the urinary tract by urinary cytology
Abstract
1122 cytological diagnoses have been made on 2500 Papanicolaou stained cytological slides from Patients with urothelial carcinomas. The cytological accuracy was 78% for G1 tumours, 94% for G2 and 96% for G3 carcinomas. A histologically diagnosed G1 carcinoma was cytologically G1 in 81% of cases, a G2 carcinoma was recognized in 64% and G3 carcinoma in 48%.
