A Clinicopathologic Study of Urinary Bladder Lesions Amongst North Indian Population: An Experience From a Tertiary Care Centre.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundUrinary bladder cancer (UBC) is amongst the most common urological malignancies.
aimTo study different types of urinary bladder lesions in the north Indian population and to correlate various clinical and pathological findings. MATERIALS AND
methodsThe present prospective study was conducted on 100 cases undergoing transurethral resection of bladder tumor (TURBT) and/or radical cystectomy over a period of 2.5 years followed by histopathological examination. Liquid-based cytology for malignant cells in urine was also performed. Immunohistochemistry was employed for tumor typing wherever needed.
resultsA total of 100 cases were studied. Male to female ratio was 15.7:1 and most of the patients were in the sixth decade (40%). Painless hematuria was the commonest clinical presentation (60%) and smoking was the commonest risk factor (80%). The most common lesion was infiltrating urothelial carcinoma seen in 72 cases followed by papillary urothelial neoplasm of low malignant potential (PUNLMP) seen in eight cases. Grade and depth of invasion were assessed and correlated. Several variants of infiltrating urothelial carcinoma such as squamous differentiation, glandular differentiation, microcystic, clear cell, nested, and micropapillary were also identified. Clinical, cystoscopic and histopathological findings were correlated in all the cases.
conclusionInfiltrating urothelial carcinoma high grade was the most common bladder lesion identified and muscle invasion was more common with higher-grade lesions. A decade-younger age group was found to be more affected in the present series. Urine cytology for malignant cells is useful for early diagnosis of cancer. Immunohistochemistry is an important ancillary adjunct.
