PREVALANCE OF UROTHELIAL CARCINOMA, ITS HISTOLOGICAL GRADE AND TYPE IN URINARY BLADDER OVER A PERIOD OF 2 YEARS: A STUDY IN A TERTIARY HOSPITAL IN CENTRAL INDIA

Abstract

BACKGROUND:-Urinary bladder carcinoma is well known to show many histological divergent differentiation. The histological variants have important diagnostic, prognostic and therapeutic implications. The aim of the study was to find the prevalence of urothelial carcinoma in a tertiary care centre and to find the proportion of different histological grades and types of urothelial carcinoma. MATERIAL AND METHODS:- A retrospective monocentric study was done between April 2020 and April 2022 which includes 37 bladder biopsies which were received in the histopathology section of the Department of Pathology, Gajra raja medical college. Patients who refuse to give consent and those having cystitis were excluded from the study. RESULTS AND OBSERVATIONS :- Out of total 37 cases which were reviewed, the mean age was 62 years, with a male predominance (M:F ratio-3.16). Out of 37 cases, there were 8 cases each of highgrade urothelial carcinoma(21.6 %), high grade urothelial carcinoma with invasion ( 21.6 %) and high grade papillary urothelial carcinoma with invasion ( 21.6 %). There were 4 cases of high grade urothelial carcinoma with invasion with squamous differentiation ( 10.8 %), one case each of recurrent high grade urothelial carcinoma with invasion ( 2.7 %), well differentiated invasive glandular adenocarcinoma NOS (2.7%) and invasive micropapillary urothelial carcinoma with squamous differentiation ( 2.7 % ), two cases each of low grade urothelial carcinoma - 2 cases ( 5.4 %), low grade papillary urothelial carcinoma ( 5.4%) and papillary urothelial neoplasm of low malignant potential ( PUNLMP) ( 5.4 %). CONCLUSION Urinary bladder carcinoma is more common in male than females. Average age of presentation is 62 years in present study. High grade urothelial carcinoma ( 83.8 %) is more common compared to low grade ( 10.8% ). H&E staining with ancillary techniques like immunohistochemistry or molecular it can be very effective in to analyse histological variants to better understand this invasive disease hence aiding in further management of patients.
