A Fatal Case of Metastatic Primary Gastric Melanoma: Diagnostic Challenges and Therapeutic Dilemmas.
Article in Cancer management and research, 2025. 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
Background: Primary gastric malignant melanoma (PGMM) is an exceedingly rare non-epithelial tumor. Only a limited number of cases have been documented, posing significant diagnostic and therapeutic challenges. Case Presentation: A 75-year-old man presented with cough and sputum. Computed tomography (CT) suggested a malignant tumor with multiorgan metastasis. Gastroscopy revealed multiple polypoid lesions, and histopathology confirmed melanoma. After multidisciplinary discussion, primary gastric melanoma was diagnosed. Despite aggressive treatment, the disease progressed rapidly, and the patient died six months after diagnosis. Conclusion: This case highlights the importance of early endoscopy in patients with metastatic tumors of unknown origin. Although outcomes remain poor, this report contributes to the understanding of PGMM diagnosis and management.
