Primary small-cell carcinoma in the lung was found after the cold snare polypectomy of the small metastatic lesion in the cecum: A case report.

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
Metastasis from small-cell lung cancer to the colon is very rare. A 74-year-old man without respiratory or abdominal symptoms underwent a follow-up lower gastrointestinal endoscopy after a polypectomy. He was diagnosed with a 5 mm IIa non-hyperplastic polyp in the cecum and underwent a cold snare polypectomy. The histopathological findings confirmed the diagnosis of small cell carcinoma. The tumor was positive in the deep margins of the submucosal layer. Subsequent systemic examination revealed a mass in the lower lobe of the left lung. Thus, the tumor in the cecum was determined to be a colorectal metastasis from primary small-cell carcinoma of the lung. Metastasis to the colon was diagnosed as small-cell lung cancer based on local positivity for thyroid transcription factor-1 and morphologic and immunochemical features. To our best knowledge, this is the first report of colon metastasis from small cell carcinoma identified by endoscopic treatment.
