Prognostic Factors Influencing Postoperative Survival in Patients With Neuroendocrine Carcinoma of the Bladder: A Population-Based Study.
Article in Cancer medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThis study aimed to identify prognostic factors influencing survival in patients with bladder neuroendocrine carcinoma (NC).
methodsThis study utilized the Surveillance, Epidemiology, and End Results (SEER) database (2004-2015) to compare NC with urothelial carcinoma (UC). We evaluated the prognostic value of clinicopathological characteristics and survival outcomes for bladder NC patients. Multivariable Cox proportional hazard models and propensity score matching (PSM) were employed for analysis.
resultA total of 99,704 patients were included, with 603 in the NC group and 99,101 in the UC group. Compared with the UC group, the NC group was inclined to receive radical cystectomy (34.2% vs. 12.2%), radiation (25.0% vs. 4.6%) and chemotherapy (62.0% vs. 22.2%) as treatment options. Multivariate Cox regression analysis revealed higher overall survival (OS) and cancer-specific survival (CSS) outcomes for NC patients who underwent radical cystectomy (HR = 0.569, 95% CI = 0.537-0.603, p < 0.001; HR = 0.531, 95% CI = 0.489-0.577, p < 0.001; respectively). To mitigate bias, a 1:1 propensity score-matched analysis was performed on both groups, resulting in 1202 patients (n = 601 per group). Multivariate Cox regression analysis identified seven risk factors for OS and CSS: age at diagnosis, race, cT stage, cN stage, cM stage, histological type, and chemotherapy. Additionally, surgery of the primary site was a prognostic factor for OS. A better prognosis was observed for NC patients who underwent radical cystectomy compared to those who did not. NC patients who only received radical cystectomy have a better prognosis in both OS (log-rank p = 0.002) and CSS (log-rank p = 0.009) compared with those who only received radiotherapy.
conclusionAge, race, TNM stage, chemotherapy, and surgery were identified as independent predictors of bladder NC patients. Radical cystectomy may represent the optimal therapeutic approach to improve the prognosis of NC patients.
