Colonic Leiomyosarcoma Treated With Laparoscopy-Endoscopy Cooperative Surgery for Colorectal Tumors (LECS-CR) Resulting in Peritoneal Dissemination Recurrence: 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
Gastrointestinal leiomyosarcoma is a rare tumor, particularly in the colon. We report a case of colonic leiomyosarcoma treated with laparoscopy-endoscopy cooperative surgery for colorectal tumors (LECS-CR) and discuss its feasibility and limitations. A 57-year-old man presented with a submucosal tumor in the ascending colon detected following a positive fecal occult blood test. LECS-CR was performed for both diagnostic and therapeutic purposes. Histopathological examination confirmed leiomyosarcoma. Although complete resection was achieved, peritoneal dissemination recurrence at the anastomotic site was observed one year postoperatively, requiring open right hemicolectomy. No recurrence has been observed during the six months following the second surgery. While LECS-CR may represent a minimally invasive treatment option, strategies to prevent tumor dissemination associated with bowel opening procedures remain a critical issue. This case highlights the potential limitations of LECS-CR in leiomyosarcoma and underscores the importance of appropriate patient selection and postoperative surveillance strategies.
