Nephroureterectomy for upper tract urothelial carcinoma recurrence in bladder cancer patients treated with radical cystectomy: a multicentric propensity score matched analysis on predictors, practice patterns and survival outcomes.

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
aim(I) To determine clinicopathological determinants of metachronous Upper Tract Urothelial Carcinoma (UTUC) requiring Radical Nephroureterectomy (RNU) after Radical Cystectomy (RC). (II) To evaluate long-term survival of patients who underwent RC + RNU compared with matched RC only controls.
methodsPatients undergoing RNU for metachronous UTUC were extracted from a multi-institutional RC database. A 1:2 Propensity Score Match (PSM) was performed based on age, gender, BMI, CCI, Smoking Status, and cT stage between RC only and RC + RNU patients. Simon-Makuch plots, landmark analyses and Multivariable Cox regressions were adopted to compare survival outcomes.
resultsOf 1804 RC patients, 85 (4.7%) underwent subsequent RNU. At multivariate regression, younger age, smoking history, BCG exposure, NMIBC, CIS and positive ureteric margins were identified as positive predictors of upper tract recurrence. After PSM, 81 RC + RNU patients were matched to 157 RC only controls. Median time from RC to RNU was 29 (18-47) months, with the majority of UTUC diagnosed at a muscle-invasive stage (70.9%). Simon-Makuch curves demonstrated worse Cancer Specific Survival (CSS) of the RC + RNU cohort (HR: 6.41, 95% CI 3.16-13.04). At landmark analyses, RNU was consistently associated with an increased mortality risk from the 24th month onward. Multivariable Cox regression identified RNU and pN + as the only significant predictors of worse CSS (respectively, HR: 6.55, 95% CI 2.93-14.64 and HR: 8.45, 95% CI 3.24-21.99).
conclusionsThe worse survival outcomes and high rates of locally advanced disease found at RNU underscore the need for standardized, risk-stratified, long-term follow-up of the remnant urinary tract following RC.
