Significant impact of a history of prior or concomitant upper urinary tract cancer on the recurrence and progression of non-muscle invasive bladder cancer.
Article in Japanese journal of clinical oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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
backgroundThe objective of the present study was to evaluate the prognostic impact of the upper urinary tract cancer status on recurrence-free survival and progression-free survival, and to develop risk stratification systems that include the upper urinary tract cancer status for patients with non-muscle invasive bladder cancer. PATIENTS AND
methodsThe present study included 40 (upper urinary tract cancer-non-muscle invasive bladder cancer group) and 285 (non-muscle invasive bladder cancer alone group) patients with and without a history of prior or concomitant upper urinary tract cancer, respectively. Nine clinicopathological findings between the two groups were compared, and risk stratification systems for the recurrence and progression of non-muscle invasive bladder cancer were developed.
resultsRecurrence-free survival and progression-free survival in the upper urinary tract cancer-non-muscle invasive bladder cancer group were significantly inferior to those in the NMIBC alone group (P < 0.001 and P = 0.006, respectively). Multivariate analyses identified the following independent prognosticators: multiplicity and upper urinary tract cancer status for recurrence-free survival, and pT category and upper urinary tract cancer status for progression-free survival. Significant differences were noted by the risk stratification systems based on the positive number of independent predictors of recurrence-free survival and progression-free survival (P < 0.001 and P = 0.007, respectively). The concordance indices of recurrence-free survival were 0.627, 0.588 and 0.499 in this study stratification, EORTC risk table and CUETO model, respectively. Those of progression-free survival were 0.752, 0.740 and 0.714, respectively.
conclusionThe present results suggest the significant impact of a history of prior or concomitant UUTC on recurrence-free survival and progression-free survival in non-muscle invasive bladder cancer patients, and risk stratification systems that include the upper urinary tract cancer status for the recurrence and progression of non-muscle invasive bladder cancer are promising tools for predicting the outcomes of these patients.
