Retroperitoneal dedifferentiated liposarcoma with colon infiltration: a case report and literature review.
Article in Frontiers in oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 dedifferentiated liposarcoma (RP DDLS) is considered highly malignant, with a high recurrence rate and poor prognosis, and is usually asymptomatic until the advanced stages. Retroperitoneal liposarcoma with colon invasion is extremely rare, with only a few cases reported in the literature. This study reported the case of a 75-year-old male patient with a retroperitoneal space-occupying lesion without any clinical symptoms. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) scans suggested a neoplastic lesion. After adequate preoperative preparation, the patient underwent laparoscopic tumor resection and right hemicolectomy. Pathological and immunohistochemical examinations of the resected retroperitoneal mass and right hemicolon revealed dedifferentiated liposarcoma (DDLPS). Dedifferentiated liposarcomas are characterized by local invasiveness and a high recurrence rate. The association between dedifferentiated liposarcoma and invasive behavior observed in this patient underscores the importance of multidisciplinary collaboration as the primary treatment strategy. Nevertheless, complete tumor resection remains crucial for improving the prognosis and reducing the high local recurrence rate.
