Global Applicability of a Risk Prediction Tool for Sentinel Node Positivity in Patients With Primary Cutaneous Melanoma.

Abstract Importance: The Melanoma Institute Australia (MIA) sentinel node (SN) metastasis risk calculator provides estimates of positivity for individual patients based on 6 standard clinicopathological parameters and the full 6-parameter model has been externally validated previously using US data. However, given its geographically widespread use, further validation is required to ensure its applicability to other populations. Objective: To further externally validate the MIA SN metastasis risk calculator and increase its precision by refinement of the 95% CIs. Design, setting, and participants: A retrospective multicenter cohort study was carried out using data from 4 continents, including the national Danish Melanoma Database and cancer [...]

Health-related Quality of Life and hospital costs of Finnish melanoma patients participating in the second Multicenter Selective Lymphadenectomy Trial (MSLT-II).

Abstract Background and purpose: After reports that complete lymph node dissection (CLND) did not improve melanoma-specific survival of sentinel lymph node (SLN)-positive patients, the use of CLND has diminished but it is still carried out for selected patients. We sought to assess differences in Health-Related Quality of Life (HRQoL) and tertiary care costs among the Finnish Multicenter Selective Lymphadenectomy Trial (MSLT)-II-patients. Patients/materials and methods: A total of 52 patients randomized to CLND and 55 to nodal observation completed a modified version of the standardized and validated, RAND-36 questionnaire at baseline, 4 months and annually up to 5 years. Tertiary care costs [...]

Mohs micrographic surgery for the treatment of invasive melanoma: A systematic review with meta-analyses.

Abstract Background: The use of Mohs micrographic surgery (MMS) in melanoma treatment has divided opinion and evidence-based guidelines are lacking. Objectives: This systematic review aimed to analyse clinical outcomes for patients with invasive melanomas treated with Mohs rather than wide local excision (WLE). Methods: Embase, MEDLINE and Cochrane databases (to 30 August 2023) were searched for studies using Mohs to treat invasive melanoma. Outcomes of interest were local recurrence and death from melanoma. Results: Thirty-five articles involving 41,499 patients with invasive melanoma treated with Mohs were identified. Sixteen studies compared Mohs with WLE and 19 were Mohs-only, non-comparative studies. Patients treated with Mohs [...]

Sentinel Node Biopsy in Melanoma Remains a Valuable Clinical Tool. Comment on Dixon et al. Primary Cutaneous Melanoma-Management in 2024. J. Clin. Med. 2024, 13, 1607.

Abstract Management of melanoma in 2024 requires at times complex decision making and a multidisciplinary approach. An article by Dixon and collaborators published in this Journal contained broad-reaching recommendations, some of which are in contradiction of accepted National and International Guidelines. This article seeks to highlight these points of contention and outline widely accepted standards of care that are considered best practice. Read Full Paper
