Late solitary metastasis of chromophobe renal cell carcinoma in the residual ureter.
Article in IJU case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Introduction: Postoperative recurrence of chromophobe renal cell carcinoma is rare, and its metastatic process remains unclear. We here report a case of a solitary metastasis in the residual ureter detected 9 years after the primary surgery and discuss its possible recurrence mechanism based on our immunohistochemical study. Case presentation: A 67-year-old woman received nephrectomy for a left renal tumor, which was diagnosed as chromophobe renal cell carcinoma with urinary collecting system invasion. Nine years postoperatively, a tumor was found in the residual ureteral stump and was surgically excised. The recurrent tumor was histologically diagnosed as chromophobe renal cell carcinoma surrounded by normal urothelial cells. On immunohistochemical staining, the tumor cells showed a high expression of uroplakin-2, a urothelium-specific marker. Conclusion: In our case, highly adhesive uroplakin-2-positive cancer cells spilled from the primary site and attached to the residual ureteral stump, growing slowly while being gradually covered by normal urothelial cells.
