Ultra-late pancreatic metastases from renal cell carcinoma after nephrectomy: two case reports and a literature review.
Article in Journal of surgical case reports, 2026. 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
Pancreatic metastases of renal cell carcinoma (PM-RCC) are relatively rare. However, they exhibit unique biological behavior, often presenting as late-onset metastases with a relatively favorable prognosis. This report presents two cases of pancreatic masses detected 16 and 20 years, respectively, after radical nephrectomy for renal cell carcinoma (RCC). Both patients were asymptomatic, with the masses identified during routine health examinations. Each patient successfully underwent robot-assisted distal pancreatectomy with splenectomy. Pathological examination confirmed the diagnosis of PM-RCC in both cases, illustrating the characteristic of ultra-late metastasis in RCC. This underscores the necessity for lifelong follow-up in RCC patients and maintaining a high index of suspicion for metastasis when new pancreatic lesions are identified. Carbonic anhydrase-IX-targeted PET/CT may be helpful as an adjunct for preoperative differential diagnosis. Our findings suggest that an aggressive surgical approach may be considered for patients in whom complete resection appears feasible.
