Kidney sparing surgery in upper tract urothelial carcinoma: paradigm change in surgical treatment for ureter cancer.
Article in Journal of cancer research and clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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 extend the indications of kidney-sparing surgery (KSS) for ureter cancer by comparing the oncological outcomes between patients with upper tract urothelial carcinoma (UTUC) who underwent radical nephroureterectomy (RNU) or KSS.
methodsWe retrospectively reviewed 708 patients with UTUC who underwent RNU (N = 646) or KSS (N = 62) between 2011 and 2019 to analyze the oncologic outcomes and prognostic factors. Subgroup analyses were performed for patients with unifocal ureteral urothelial carcinoma (UC).
resultsNo significant difference was observed in the overall survival (OS) or cancer-specific survival (CSS) between RNU and KSS (distal ureterectomy with reimplantation (N = 33), ureterectomy with ileal ureter (N = 14), ureteroscopic tumor resection (N = 10), and ureterectomy with ureteroureterostomy (N = 5)). Among 269 (38.0%) patients with unifocal ureteral UC, 219 and 50 patients underwent RNU and KSS, respectively. OS and CSS were not significantly different between these two groups. Pathologic stage was a significant risk factor in multivariate analysis (hazard ratio = 2.621; p = 0.000). Among 646 RNU patients, 219 (33.9%) had unifocal ureteral UC, 40 (18.3%) with low-grade tumors. Among these, 13 (5.9%) patients with unifocal, low-grade and small (< 2 cm) tumors received nephroureterectomy.
conclusionKidney-sparing surgery should be regarded as an important alternative to RNU for patients with unifocal ureteral UC thought to have noninvasive disease to preserve renal function and reduce overtreatment.
