Metastatic Oncocytic Renal Neoplasm Presenting as Gastrointestinal Bleeding.
Article in Cureus, 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
Renal cancer (RC) is known for its diverse clinical presentations and unpredictable behavior. While it often metastasizes to common sites such as the lymph nodes, lungs, bones, and liver, its potential to metastasize to the gastrointestinal tract (GIT) is relatively rare. We report an unusual case of an 87-year-old male patient with a history of metastatic oncocytic renal neoplasm who presented with intermittent rectal bleeding. Colonoscopy revealed a bleeding mass in the sigmoid colon. Biopsy confirmed metastatic renal neoplasm, consistent with prior pathology. Immunohistochemistry was positive for AE1/AE3, CAIX, and PAX-8, supporting renal origin. Recent CT imaging showed enlargement of the left renal mass with direct extension into the descending colon and associated lymphadenopathy. Metastasis of RC in the GIT, especially the colon, is rare and even more so in oncocytic subtypes. This case underscores the importance of considering RC in patients with GI bleeding and a history of renal neoplasm. Early recognition and individualized, multidisciplinary management are crucial for optimal outcomes.
