Late solitary pancreatic metastasis from clear-cell renal cell carcinoma: A case report.
Article in Journal of family medicine and primary care, 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
Solitary pancreatic metastasis from renal cell carcinoma (RCC) is uncommon and may present decades after nephrectomy. We report an unusually late (17-year) solitary pancreatic metastasis from clear-cell RCC treated with curative resection. A 66-year-old man with a prior right nephrectomy 17 years earlier presented with 3 months of unintentional weight loss. Contrast-enhanced computed tomography (CECT) demonstrated an 8.0 × 5.0 cm hypervascular exophytic mass in the pancreatic neck body. Tumor markers (CEA, CA19-9) were within normal limits. Because of lesion vascularity, preoperative percutaneous biopsy was deferred. The patient underwent distal pancreatectomy with splenectomy. Gross and histology showed sheets of polygonal clear cells with prominent vasculature; immunohistochemistry was positive for CD10 and PAX8 and negative for synaptophysin and chromogranin, confirming metastatic clear-cell RCC. Resection margins were negative (R0). The patient declined adjuvant systemic therapy and remains disease-free at 36 months post-surgery. This case illustrates the potential for extremely late solitary pancreatic metastasis from RCC and underscores the importance of lifelong surveillance in RCC survivors. In selected patients, complete surgical resection can achieve durable disease control, even in the absence of adjuvant therapy.
