Metastatic Renal Cell Carcinoma Detected by Postprandial Abdominal Pain: A Case Report.
Article in Cancer reports (Hoboken, N.J.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundRenal cell carcinoma (RCC), a prevalent malignancy in China, manifests annually in excess of 70 000 instances. At initial diagnosis, approximately one-tenth of these patients present with metastatic disease. The predominant sites for distant dissemination encompass pulmonary, osseous, hepatic, and adrenal regions, whereas gastric involvement remains exceedingly rare. We clinically characterized a case by postprandially abdominal discomfort, which was endoscopic-biopsy confirmed as a gastric tumor, and further diagnosis revealed the primary malignancy was kidney-originated. CASE: A 68-year-old male was admitted to our hospital for the evaluation of persistent postprandial abdominal pain and diarrhea that had persisted for 1 month. Gastroscopy revealed a gastric body tumor, leading to the performance of an endoscopic submucosal dissection (ESD). The initial pathological examination identified the tumor as gastric malignancy of undetermined origin. Concurrently, a comprehensive abdominal CT scan detected an additional renal tumor. Subsequent radical nephrectomy of the right kidney was performed, and the pathology confirmed the renal cell carcinoma shared the same origin as the gastric lesion. Over a follow-up period of 38 months postoperatively, there has been no evidence of tumor recurrence or progression.
conclusionRenal cell carcinoma has the potential to metastasize to the stomach, albeit this occurrence is not readily detectable in clinical practice unless it manifests as gastric symptoms. In instances where solitary superficial gastric metastasis is identified, aggressive surgical intervention can yield satisfactory clinical outcomes.
