Chondroid gastrointestinal stromal tumor in the stomach with early adenocarcinoma.

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
objectiveTo explore the pathologic features of gastric chondroid gastrointestinal stromal tumors.
methodsThe clinicopathologic data of one case of gastric chondroid gastrointestinal stromal tumor were collected and the features were analyzed by literature review.
resultsThe male patient was 64 years old and had suffered from upper abdominal fullness discomfort without obvious cause for 5 years. Gastroscopic examination showed a rough area located in the lesser curvature of the gastric antrum, measuring 6 cm × 4 cm. CT scan showed the stomach wall was unevenly thick at the gastric antrum and stomach outlet. Multiple enlarged lymph nodes were seen nearby. The biopsy pathology showed adenocarcinoma of gastric antrum. The patient underwent laparoscopic gastrectomy and gastric chondroid gastrointestinal stromal tumor was found with adenocarcinoma of the stomach. Asp842Val mutation was found in the PDGFRα 18 exon.
conclusionGastric chondroid gastrointestinal stromal tumors are rare and low risk. Tumor cells express CD117 and Asp842Val mutation in the PDGFRα 18 exon revealed by genetic sequencing suggesting this kind of tumor might be resistant to imatinib.
