1 · What the graph read from it

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.

2 · The registry

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 soft tissue sarcoma of adipocyte origin. Liposarcoma represents 20-30% of adult soft tissue tumors, which was most frequently seen in the retroperitoneal space in 45% and abdominal space in only 5% of cases, but the multicentric case is unknown. Herein, we describe a rare case of multicentric, large, intra-abdominal and retroperitoneal liposarcoma, one of which had caused infection and pressing the right ureter causing hydronephrosis, which was resected by two-stage surgery. CASE PRESENTATION: The patient was a 46-year-old man who was referred for abdominal bloating and fatigue. Enhanced computed tomography showed a 23-cm intra-abdominal tumor and a 14.6-cm left retroperitoneal tumor. The intra-abdominal tumor which compressed the right ureter caused right unilateral hydronephrosis and deteriorated the renal function. The intra-abdominal tumor had also formed an intra-abdominal abscess. We performed emergent laparotomy and resected the intra-abdominal tumor. After the recovery of renal function, we resected the residual retroperitoneal tumor. Histopathological examination showed both tumors to be myxoid/round cell type liposarcoma. Considering clinical findings and their location, he was diagnosed with multicentric liposarcoma. He underwent adjuvant chemotherapy and has been alive without any recurrence for 9 months after the operation.

conclusionsWe successfully resected large intra-abdominal and retroperitoneal multicentric myxoid/round cell liposarcomas. A two-stage surgery was a rational choice as it provides time to confirm the recovery of renal function.
