Malignancy in Chronic Leg Wounds: Diagnostic Delay and Clinical Implications in a Tertiary Wound-Care Cohort.
Observational study in International wound journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Chronic leg wounds are common in wound-care practice and are most often attributed to vascular or inflammatory etiologies. Rarely, they may represent or conceal underlying malignancy, and delayed recognition can lead to inappropriate management and poor outcomes. We aimed to evaluate diagnostic delay, clinical warning signs, histopathological findings, management strategies, and outcomes in patients with malignancy-associated chronic leg wounds treated in a tertiary wound-care setting. We conducted a retrospective observational study of consecutive patients with chronic lower-leg wounds (> 6 weeks' duration) diagnosed with underlying malignancy between 2015 and 2022. Clinical characteristics, time to biopsy, histopathological findings, treatment, and outcomes were analysed descriptively. Among 328 patients with chronic leg wounds, eight (2.4%) were diagnosed with malignant etiologies. Mean ulcer duration at biopsy was 11.3 months (range 6-24), exceeding guideline-recommended timelines. All wounds failed to heal despite standard care. Common red-flag features included disproportionate pain, necrosis or bleeding, and atypical appearance. Earlier biopsy and multidisciplinary management were associated with improved wound outcomes, whereas prolonged diagnostic delay correlated with advanced disease and poor prognosis. Malignancy should be considered in any chronic leg wound failing to improve within 4-12 weeks or showing atypical features, and early biopsy is essential to optimise outcomes.
