FRIDAY, Jan. 13, 2023 (HealthDay News) — The Melanocytic Pathology Assessment Tool and Hierarchy for Diagnosis (MPATH-Dx) has been revised to simplify diagnoses into four classes, according to a consensus statement published online Jan. 11 in JAMA Network Open<\/em>.<\/p>\n Raymond L. Barnhill, M.D., from the Institut Curie in Paris, and colleagues revised the MPATH-Dx version 1.0 classification tool using feedback from dermatopathologists and members of the International Melanoma Pathology Study Group. All feedback was integrated into an updated and refined MPATH-Dx version 2.0.<\/p>\n The researchers note that in order to improve diagnostic concordance and provide more explicit guidance for treatment, the new MPATH-Dx version 2.0 schema simplifies the original five-class hierarchy into four classes. Histopathological criteria for classification of classes I and II lesions are clearly defined in the new version; specific provisions are made for the most frequently encountered low-cumulative sun damage pathway of melanoma progression and other less common pathways to melanoma; guidance is provided for classifying intermediate class II tumors versus melanoma; and a subset of pT1a melanomas with very low risk is recognized.<\/p>\n “We expect that the implementation of the new revised MPATH-Dx V2.0 schema into routine practice will provide a robust tool and adjunct for standardized diagnostic reporting of melanocytic lesions and management of patients to the benefit of both health care practitioners and patients,” the authors write.<\/p>\n Several authors disclosed financial ties to the biotechnology and pharmaceutical industries.<\/p>\n
