Left-sided compartmental resection of an 18 kg retroperitoneal liposarcoma: a case report.
Article in Journal of surgical 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
Retroperitoneal liposarcomas are uncommon malignancies that often remain clinically silent and may attain massive size at diagnosis. Complete surgical excision with negative margins is the cornerstone of treatment; however, this is technically challenging due to indistinct anatomical planes and proximity to major vascular and visceral structures. Compartmental resection has been advocated to improve oncological outcomes, particularly with regard to local recurrence. We report a 43-year-old hypertensive male who presented with progressive abdominal distension and left-sided abdominal pain. Imaging demonstrated a large fat-containing retroperitoneal mass extending across the midline with multivisceral involvement. The patient underwent left-sided compartmental resection, including left nephrectomy, distal pancreaticosplenectomy, and left hemicolectomy. The resected specimen weighed 18 kg. Histopathology reported a dedifferentiated liposarcoma with negative margins. This case demonstrates the safety and feasibility of compartmental resection in achieving R0 resection in massive retroperitoneal liposarcoma.
