Clinicopathological features and differential diagnosis of gastric metastases.
Article in World journal of surgical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveDue to the rarity and non-specificity of symptoms, gastric metastases are often misdiagnosed, and patients are not treated promptly. The aim of this study was to study the clinicopathological features and differential diagnosis of gastric metastases.
methodsFrom 2004 to 2021, 14 patients were diagnosed with gastric metastases not resulting from direct invasion (GMNDI) in our hospital, and their imaging and clinicopathological features were analyzed.
resultsPET-CT examination showed hypermetabolic nodules in the stomach. Under gastroscopy, GMNDI showed eminence, nodular or vegetable pattern mass, and ulcer. Microscopically, GMNDI showed similar pathological features and immunophenotypes to the primary tumor. In our study, the most common primary tumors were malignant melanoma (4 cases), small cell lung cancer (3 cases), and hepatocellular carcinoma (3 cases). Immunohistochemistry contributed to the pathological diagnosis and differential diagnosis of gastric metastases. Malignant melanoma expressed HMB45, MelanA, and S-100; small cell lung cancer expressed TTF-1, CD56, and CgA; hepatocellular carcinoma expressed GPC-3, hepatocyte, and Sall4. In a few cases, tumor cells may lose immune markers during metastasis. Therefore, it is necessary to combine medical history, imaging examination, and other clinical diagnosis methods in the pathological diagnosis.
conclusionAn in-depth understanding of GMNDI is conducive to better diagnosis and treatment planning for gastric metastases and subsequent improvement in patient prognosis.
