Myxoid liposarcoma of sigmoid mesocolon: a case report and review of the literature.
Review in Journal of medical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLiposarcoma is a malignant mesenchymal tumor most commonly arising in the extremities and retroperitoneum. Involvement of the mesentery is rare, and primary liposarcoma of the large bowel mesentery has been reported fewer than 15 times in the English literature. Among its histological subtypes, myxoid liposarcoma is exceptionally rare in this location, with only four previous cases described. Owing to its rarity, there are no standardized management protocols, although wide surgical excision with negative margins remains the mainstay of treatment. CASE PRESENTATION: We report a 73 year-old Arab male with hypertension and ischemic heart disease who presented with painless abdominal swelling and anorexia. Imaging revealed a large left mesocolon mass, and a left hemicolectomy with colosigmoid anastomosis achieved R0 margins. Histopathology confirmed primary myxoid liposarcoma of the mesocolon. The patient had an uneventful recovery and remains disease-free 1 year after surgery.
conclusionPrimary myxoid liposarcoma of the mesocolon is extremely rare, with this case representing only the fifth reported instance. Review of the literature indicates that complete surgical resection is the cornerstone of management, while the role of adjuvant radiotherapy or chemotherapy remains controversial. Reporting additional cases is essential to improve understanding, refine prognostic assessment, and guide the development of evidence-based treatment strategies.
