A correlative study on urinary cytology and FDP with cystoscopy and pathology in the urinary bladder cancers.

Abstract

In view of comparatively-high incidence of papillary, well or moderately-well differentiated, transitional cell carcinomas in urology, and of frequent recurrence of carcinomas after appropriate procedures, we have undertaken the correlative study on urinary cytology with cystoscopy, pathology and the amount of fibrinogen and degradation products of fibrinogen and fibrin (FDP). Cytopathologically, 191 cases were confirmed histologically for cancers out of 442 cases studied cytologically; among these 442 classes IV and V were found in 136 cases, and 99 of 136 cases (72.8%) had cancers. Admittedly, we were unable to suspect tumors cytologically in 24.5% of the cases. As to histological gradings and cytology, 48.7% of classes I and II in well differentiated were found against 52.9% and 57.1% of classes IV and V in moderately-well and poorly differentiated carcinomas, respectively. Urinary FDP assay was quite promising; out of 19 cases with both positive cytology and FDP, 18 (94.7% had carcinomas histologically, whereas 12 of 56 cases (21.4%) with both negative cytology and FDP bore cancers. Subsequently, several proposals for improving the diagnostic accuracy were discussed. We concluded the importance of accumulating more cases by combining several diagnostic procedures, especially among well and moderately-well differentiated carcinomas.
