Surgical resection of massive liposarcomas at the extremities: a 10-year experience in a referral musculoskeletal sarcoma unit.
Observational study in World journal of surgical oncology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThere is still no consensus regarding the management of patients with massive liposarcomas located in the extremities. Several discrepancies related to the aggressiveness of the surgery and the application of concomitant radiotherapy and chemotherapy treatments remain controversial. The purpose of this study was to analyse the clinicopathological characteristics, prognostic factors and outcomes of a series of patients with massive liposarcomas of the extremities who were treated at a referral hospital specializing in musculoskeletal oncology.
methodsThis was an observational, descriptive and retrospective case series covering 10 years of clinical practice. The records of 26 adults, 14 men and 12 women, with localized massive liposarcomas in the extremities were studied. The average age was 53 years. The patients were treated from January 2003 until January 2012. Wide surgical resections with limb-sparing surgeries were performed for most patients (96.2 %).
resultsThe average tumour size was 15.1 ± 6.8 cm in the greatest dimension. Regarding the histological subtypes, there were 11 well-differentiated or atypical lipomatous tumours (42.3 %), 10 myxoid (38.5 %) and 5 (19.2 %) round cell and pleomorphic liposarcomas. Regarding the malignancy grades, 19 cases (73 %) were classified as low grade. Among these low-grade tumours predominated the well-differentiated subtype (57.9 %). Within high-grade tumours, the round cell and pleomorphic subtype was most frequent (57.1 %; p = 0.011). Radiotherapy was additionally applied to 12 patients (46.2 %) and adjuvant chemotherapy to 5 (19.3 %). Tumour recurrence was observed in only 2 cases (7.7 %). Only 1 of these cases developed lung metastatic dissemination.
conclusionsAcross the entire series, these massive tumours did not compromise the survival of the patients. The histologic subtype and the malignancy degree were closely related. Proper and early diagnosis and therapeutic management of these patients via the application of wide-margin surgical excision are essential to ensure long-term survival.
