Tubular damage marker as a predictive factor for pathologically upstaged renal cell carcinoma.
Article in World journal of urology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo investigate if increased tubular damage biomarker can predict pathologically upstaged renal cell carcinoma (RCC), which may possess sub-radiologic invasive behavior, leading to surrounding tubular damage. MATERIALS AND
methodsWe examined 1563 patients with surgically resected RCC between March 2016 and June 2021 from the prospective database SUPER-RCC-Nx. Exclusion criteria were cancer not originating from the kidneys, benign renal tumor, and end-stage renal disease.
resultsOf 1297 patients, 131 had a clinically high T stage (T3-4), whereas 1166 had a low one. Patients with a clinically low T stage were subgrouped into identical-stage (n = 1041) and upstaged (n = 125) groups, who were confirmed as a pathologically high T stage. The upstaged group had older age (p = 0.003), larger tumor size (5.72 ± 3.24 vs. 3.12 ± 2.08, p < 0.001), higher Fuhrman grade (grades 3-4) (57.3% vs. 47.1%, p = 0.032), and higher urine N-acetyl-beta-D-glucosaminidase/creatinine (NAG/Cr) (5.13 ± 4.78 vs. 4.05 ± 2.84, p = 0.026). Tumor size (> 4 cm; odds ratio = 10.2, p < 0.001) and urine NAG/Cr (odds ratio = 1.16, p = 0.003) were independently associated with pathological upstaging in patients with normal renal function, while age and tumor size were significant risk factors in those with decreased renal function. The receiver operating characteristic curve analysis showed that the model using tumor size and urine NAG/Cr strongly predicted pathological upstaging (area under the curve, 0.84).
conclusionUrine NAG/Cr may be a useful biomarker predicting pathologically upstaged RCC. Clinicians should be prudent in making management decisions when a large RCC is accompanied by an increased urine NAG/Cr.
