Gastric Ewing sarcoma/primitive neuroectodermal tumor: A case report.
Article in Oncology letters, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Ewing sarcoma/primitive neuroectodermal tumors (ES/PNETs) may arise in bone or soft tissue; however, these tumors rarely originate in the stomach. To the best of our knowledge, only four cases have previously been reported in the English-language literature. A 41-year-old Japanese woman was admitted with abdominal pain and underwent gastrectomy to remove the primary tumor. Immunohistochemistry, chromosomal karyotype and molecular analysis using reverse transcription-polymerase chain reaction were performed in the tumor specimens obtained. Tumor cells showed positive immunoreactivity for CD99, vimentin, CD117 (c-kit), S100, chromogranin A and synaptophysin. The tumor was a gastric ES/PNET with the EWS-FLI1 fusion gene translocation t(11;22)(q24;q12). Multiple repeat metastasectomies, as well as multi-agent chemotherapy and radiotherapy were performed for recurrent disease. Despite treatment, the patient succumbed due to progressive disease 110 months after the initial surgery for gastric ES/PNET. A review of the reported cases suggests that patients with gastric ES/PNETs have an unfavorable prognosis following resection due to the high propensity of these tumors to metastasize. Thus, multimodal treatment approaches including surgery, as well as multi-agent chemotherapy and radiotherapy may provide a survival benefit for patients with gastric ES/PNETs.
