Clinicopathological Factors Predicting Melanoma Recurrence: A Study From South East Ireland.

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
introductionCutaneous malignant melanoma is a neoplastic transformation of melanocytes and a major cause of skin cancer-related mortality. Ireland, with its fair-skinned population, continues to see rising incidence rates, highlighting the importance of identifying clinicopathological predictors of recurrence.
objectivesTo assess the relationship between excision margins and melanoma recurrence, with emphasis on anatomical distribution and clinicopathological features.
methodsThis retrospective observational study analyzed 565 patient records from University Hospital Waterford, Ireland, meeting predefined criteria. Data collected included age, sex, primary tumor site, disease stage, Breslow thickness, Clark level, mitotic figures, ulceration, lymphovascular invasion, sentinel lymph node involvement, and adequacy of excision margins. Statistical analysis was conducted using SPSS 26.0.
resultsSignificant predictors of recurrence included age ≥65 years, Breslow thickness >4.0 mm, Clark level IV-V, ulceration, lymphovascular invasion (P<0.001), and positive sentinel lymph node biopsy (P=0.004). Inadequate excision margins were also linked to increased recurrence. Conversely, early-stage disease, thin Breslow lesions (≤1.0 mm), and Clark level II were associated with lower recurrence risk.
conclusionsThis study demonstrates a significant association between narrow excision margins and melanoma recurrence, particularly in anatomically complex areas like the head and neck. The findings underscore the importance of individualized surgical planning to ensure oncological safety while preserving function and appearance. Adherence to excision margin guidelines and long-term follow-up are essential, especially in patients with high-risk histological features.
