Phyllodes tumors of the breast: Real world data from a multi-institution cohort.
Article in Breast (Edinburgh, Scotland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionPhyllodes tumors (PT) are rare breast lesions arising from fibroepithelial stroma and may be hard to clinically distinguish from fibroadenomas. They are defined as benign, borderline or malignant. The purpose of this study was to describe diagnostic workup and surgical management, and to investigate incidence of local recurrence (LR) and overall survival (OS) in relation to tumor subtype, size, age, surgical margins, surgical method, and year of diagnosis.
methodsRetrospective cohort study of all patients surgically treated for a PT in Stockholm, Sweden from 1999 to 2018. Descriptive analyses were performed, and regression models were used to analyze associations between selected covariates and LR and OS.
resultsAmong 191 patients, 132 were treated for a benign PT, 40 for a borderline PT and 19 for a malignant PT. Preoperatively, results from diagnostic workup were often ambiguous, and only 45.6 % of cases had a preoperative diagnosis of PT. Initial surgery was breast-conserving in 93.2 % of patients. Recurrences occurred in 10.5 % of the total cohort. 5-year and 10-year OS was 96.1 % and 93.5 %, respectively, for the entire cohort. In a multivariable analysis, neither covariate was associated with risk of LR. Distant recurrences were only detected among patients with malignant PT.
conclusionsIn the workup of PT, common diagnostic methods such as FNAC, CNB, and mammography may be unreliable, and clinical suspicion plays a critical role in guiding pre-operative decision-making. We found no association between surgical margins and rate of LR or OS. We found no evidence of metastatic potential in benign or borderline PT.
