CK7-negative and CK20-Positive intestinal- type gastric adenocarcinoma metastasis to the bladder: A case report of an unprecedented phenotype.
Article in Urology case reports, 2025. 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
The majority of bladder tumors (around 90 %) are urothelial carcinomas, while metastatic secondary tumors are extremely rare, comprising less than 2 % of cases. Gastric adenocarcinoma rarely metastasizes to the bladder, and these metastases typically exhibit a CK7-positive, CK20-negative phenotype. To date, there have been no reports of gastric cancer metastasis to the bladder that displays a CK7-negative and CK20-positive profile. This article presents a rare case of a patient who had previously undergone subtotal gastrectomy for gastric adenocarcinoma and later presented with macroscopic hematuria, where a CK7-negative, CK20-positive secondary adenocarcinoma was detected in the bladder.
