Clinicopathological characteristics and assessment of risk factors for incidentally discovered prostatic cancer in patients undergoing radical cystectomy with urothelial carcinoma of the bladder.

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
Background: This retrospective study analyzed data from patients undergoing radical cystoprostatectomy (RCP) for bladder urothelial carcinoma. We analyzed their features with regard to prevalence, clinicopathological characteristics and evaluated the risk of incidental prostatic adenocarcinoma (IPCa). Methods: Clinical data and pathological features of 237 patients who underwent standard RCP for bladder urothelial carcinoma were included in this study. Correlations between bladder tumor size, number of tumors, histological grade, pathological stage, patient age, and incidental prostate cancer were examined. Human epidermal growth factor receptor 2 (HER2) expression was evaluated using immunohistochemistry (IHC), and its association with clinicopathological features was analyzed. Results: Among the 237 patients, 69 (29.1%) had bladder urothelial carcinoma complicated by IPCa. Age was identified as a risk factor for IPCa (OR = 1.04, 95% CI: 1.00-1.07, Conclusions: IPCa is not uncommon in patients undergoing radical cystectomy. It is of great significance to evaluate the risk factors for informing surgical strategy and postoperative management. Our analysis further demonstrates that HER2 expression status correlates significantly with tumor size and histology in urothelial carcinoma. Specifically, tumors with HER2 2+ expression exhibited a smaller median diameter, while the classic histological subtype was predominantly observed in HER2 0/1+ tumors. These associations indicate that differential HER2 expression may delineate distinct pathological phenotypes of bladder urothelial carcinoma.
