| Summary: | Aim: Malignant melanoma is the fifth commonest invasive cancer in Ireland. The British Association of Dermatology (BAD) guidelines are currently the recognized standard for melanoma related surgery. The aim was to examine adherence to BAD guidelines and establish contributing factors resulting in non-adherence to guidelines in a group of melanoma patients in the South East Region of Ireland. Methods: A retrospective review of a prospectively maintained melanoma registry of all patients undergoing surgery in the South East Region of Ireland from January 2011 to 2016 was performed. Data were analyzed using SPSS statistical software. Univariate analysis using logistic regression was performed to examine factors associated with not meeting the BAD margin excision guidelines Data with a p < 0.05 was analyzed using a multivariate logistic regression model. Results: 459 patients underwent surgery for invasive cutaneous melanoma. 314 (68.4%) surgeries had excision margins adequately recorded and of these 234(74.5%) fulfilled the BAD guidelines. 267(58.2%) patients (2011–2016 inclusive) qualified for sentinel lymph node biopsy (SNLB) with a cancer staging of pT1b or higher. Of these patients 100(37%) agreed to proceed to a SNLB following informed discussion. 33 had a positive sentinel node. On multivariate analysis inadequate margins were independently associated with tumor thickness 2.01–4.00 mm (p = 0.0001) and >4.00 mm (p = 0.0001) and head and neck location (p < 0.0001). Conclusions: Adherence to BAD guidelines in the South East is good but requires optimization since centralization of melanoma treatment in 2013 to a single specialized center. It is important that Clinicians are fully aware of the implications of not achieving adequate excision margins in surgery. Improvements in melanoma data management is needed to fully evaluate current practices in Ireland. |
