Esophageal carcinosarcoma in which the sarcomatous element has sloughed off: 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
introductionMost esophageal carcinosarcoma (ECS) tumors present as a polypoid tumor that is continuous with the superficial lesion and suspended by a pedicle. Here, we report a case of ECS in which a polypoid lesion sloughed off before surgery. PRESENTATION OF CASE: A 76-year-old man with dysphagia was admitted to our hospital. Esophagogastroscopy revealed a 20-mm polypoid tumor continuous with a superficial lesion and attached to the lesion by a thin pedicle in the mid-thoracic esophagus. Histopathological examination of the endoscopic biopsy showed that the superficial lesion was a moderately differentiated squamous cell carcinoma and that the polypoid tumor contained a sarcomatous element. He was diagnosed with ECS and underwent radical esophagectomy with three-field lymph node dissection. In the resected specimen, no polypoid tumor was found, and only a superficial lesion was observed. The histopathological findings revealed only squamous cell carcinoma, and the pathological diagnosis was esophageal squamous cell carcinoma, pT1bN0M0, pathological stage I. The patient was discharged from the hospital 22 days after surgery and did not experience any complications. He is currently alive and remained cancer-free for three years since surgery was performed. DISCUSSION: Due to the distinctive configuration in which the polypoid lesion was connected to the superficial cancerous lesion by a very thin pedicle, researchers suggested that the polypoid tumor, which consisted of a sarcomatous element, was sloughed off before surgery.
conclusionWe encountered a rare case of ECS in which the sarcomatous element sloughed off prior to surgical resection.
