New concept of schistosomiasis lesions of urinary bladder versus development of bladder cancer.
|
| Abstract |
Schistosomiasis haematobium precancerous lesions of urinary bladder included group 1: preneo-plastic non papillary (flat) lesions [reactive atypia, flat hyperplasia, keratinizing squamous metaplasia, glandular metaplasia, dysplasia, carcinoma in-situ (CIS)] and group 2 preneoplastic papillary lesions (typical papillary hyperplasia, atypical papillary hyperplasia, papilloma). The present work studied the content of the schistosomiasis precancerous lesions of the urinary bladder using image analyzer, thereby shedding more light on the significance on the early diagnosis of the high risky group. A total of 140 previously diagnosed schistosomiasis urinary bladder lesions (124 precancerous and 16 cancers as controls) were stained by H & E, and Feulgen stain. The mean SPF was high in CIS (22.7), dysplasia (19.6) & low in atypia (7.91). DNA ploidy, non-diploidy DNA was high in CIS (53%), papilloma, dysplasia and atypical papillary hyperplasia than flat hyperplasia, glandular metaplasia, keratinizing squamous metaplasia and typical papillary hyperplasia that were diploid indicating more tendency and aggressiveness of the first group to turn malignant than the second group.
