Tight junctions adjacent to the tumor stromal interface in invading neoplastic cells of human urinary bladder carcinomas were observed. Basal lamina, collagen and elastic fibers, and cellular debris were found next to the tight junctions. An association between microenvironment (i.e., tumor necrosis) of the invading neoplastic cells and tight junction locations was suggested.
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%.
