Multiple surgical interventions improve survival in locally recurrent retroperitoneal sarcoma: a retrospective cohort analysis.

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
Background: Locally recurrent retroperitoneal sarcoma (RPS) poses substantial clinical challenges, especially in patients experiencing multiple recurrences. This study aims to evaluate the survival benefits conferred by repeated surgical resections in the management of recurrent RPS. Methods: A retrospective cohort study was conducted involving 56 patients who underwent repeated surgical resections for locally recurrent RPS at our institution between June 2016 and September 2023. Demographic, clinical, and histopathological variables- including age, sex, tumor differentiation, FNCLCC grade, prior radiotherapy and chemotherapy, surgical margin status, and postoperative complications -were collected and analyzed. Survival outcomes were assessed using Kaplan-Meier estimates and Cox proportional hazards models. Results: The median age of the cohort was 53 years (range: 28-72), with a male-to-female ratio of 30:26. Compared to a single resection, median overall survival (OS) improved with successive surgeries: 79.3 months for two surgeries, 158.0 months for three, and 181.7 months for four. However, OS declined to 121.9 months following five resections. Tumor differentiation and FNCLCC grade were significantly associated with survival outcomes. Multivariate analysis identified age, pathological subtype, tumor grade, and number of surgeries as independent prognostic factors. Although severe adverse events (SAEs) were recorded, no 30-day postoperative mortality occurred. Conclusions: Repeated surgical resection appears to confer substantial survival benefits in patients with locally recurrent RPS, underscoring the clinical value of surgical management in selected cases. These findings highlight the importance of individualized surgical strategies, while emphasizing the need for further investigation to optimize treatment paradigms.
