1 · What the graph read from it

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.

2 · The registry

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

Gastric cancer with sarcomatous changes is relatively rare and often detected at an advanced stage. We report the case of an 82-year-old man with early stage gastric cancer exhibiting an unusual morphology with a polypoid growth of a sarcomatous component arising from a flat area of a well-differentiated adenocarcinoma. He achieved mid-term remission after endoscopic submucosal dissection (ESD). Upon admission, upper gastrointestinal endoscopy revealed a 60-mm flat elevated lesion with a nodule; no lymph node or distant metastasis was noted. He was diagnosed with early stage gastric cancer and underwent ESD. Pathological examination of the nodule revealed carcinomatous cells transitioning to atypical spindle cells and sarcomatous changes, suggesting that the sarcomatous component originated from a gastric-type adenocarcinoma. There was no local recurrence or metastasis at 21 months post-ESD. This is the first report of a case of early stage gastric cancer with a sarcomatous change that achieved mid-term outcome after ESD.
