Asystematic review and meta-analysis of clinical prognostic factors linked to extravesical recurrence after radical nephroureterectomy to treat upper tract urothelial carcinoma.

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
Objective: Numerous studies have investigated predictors of intravesical recurrence following radical nephrectomy (RNU) in patients with upper urinary tract uroepithelial carcinoma (UTUC). In contrast, extravesical recurrence (EUR) has received less focus. Consequently, this study aims to evaluate the significant predictors of EUR after RNU through a systematic review of the literature and a meta-analysis. Methodology: We conducted a computerized bibliographic search across PubMed, Embase, and Cochrane databases to identify reports that include detailed results from multivariate analyses of predictors of EUR. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the AMSTAR (Assessing the Methodological Quality of Systematic Reviews) criteria, we selected thirteen retrospective studies, each with a sample size exceeding 100 cases. Using Review Manager 5.4 software, we performed cumulative analyses of available HR and their corresponding 95% confidence intervals to evaluate potential predictors of EUR. Results: Our findings indicate that patient-specific predictors include preoperative Ki-67 with a HR of 3.61 (P = 0.003), neutrophil-to-lymphocyte ratio with an HR of 2.20 (P = 0.0005), and glomerular filtration rate with an HR of 3.35 (P = 0.0009). Tumor-specific predictors identified were tumor stage with an HR of 4.67 (P < 0.00001), lymphovascular invasion with an HR of 2.37 (P = 0.004), and lymph node status with an HR of 2.68 (P < 0.0001). Regarding treatment-specific predictors, positive surgical margins were associated with an HR of 3.97 (P = 0.0005), and adjuvant chemotherapy was associated with an HR of 1.65 (P = 0.03). Discussion: Our study identified three significant predictors across patient, tumor, and treatment dimensions for extravesical recurrence following radical nephroureterectomy in patients with upper urinary tract uroepithelial carcinoma. We hypothesize that history of bladder cancer, platelet-to-lymphocyte ratio, and urinary cytology could also be strong predictors of post- RNU extravesical recurrence in patients with upper UTUC, assuming adequate sample size and controlled heterogeneity. This research aims to provide urological clinicians with enhanced guidance for postoperative decision-making.
