Locally advanced adrenal tumor invading the stomach revealed by upper gastrointestinal hemorrhage: a case report.

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
Introduction and importance: Adrenocortical carcinoma (ACC) is a rare and highly aggressive malignancy, often diagnosed at an advanced stage. Direct invasion into adjacent organs is possible, but gastric involvement is exceedingly uncommon. We report a rare case of a locally advanced adrenal tumor invading the stomach and presenting with upper gastrointestinal bleeding. Case presentation: A 42-year-old man presented with hematemesis and melena evolving over 24 h. Physical examination revealed pallor, hypotension, and a palpable left upper quadrant mass. CT imaging showed a large left adrenal mass (15 × 14 × 10 cm) invading the posterior gastric wall and compressing adjacent structures, with thrombi in the inferior vena cava and portal vein. Hormonal studies excluded a functional tumor. Percutaneous biopsy confirmed ACC. The patient underwent en bloc resection including total gastrectomy, left nephrectomy, and partial vena cava resection with reconstruction. Histopathology confirmed high-grade ACC with negative margins. Clinical discussion: ACC rarely presents with gastrointestinal bleeding. Gastric invasion is exceptional and poses diagnostic and therapeutic challenges. Complete surgical excision remains the cornerstone of treatment and offers the best chance for prolonged survival. Conclusion: This case highlights an unusual presentation of ACC revealed by upper gastrointestinal hemorrhage, emphasizing the importance of early recognition and multidisciplinary management.
