Melanoma Excisions with 5 Millimeter Margins Linked to Less Risk of Local Recurrence
Source: HCP Live, April 2023
A T1a melanoma excision near critical structures with 5-mm margins may be adequate for a diminished risk of local recurrence compared to other excisions, according to recent findings.
This research was conducted to re-assess the current guidelines recommending surgically removing T1a melanomas with 10mm margins, despite the proximity to important facial structures such as the face, acral, scalp, genitalia, periumbilical, and perineal areas.
This study, authored by Andrea Maurichi, MD, from the Melanoma Surgical Unit at Fondazione IRCCS Istituto Nazionale dei Tumori di Milano in Italy, compared outcomes from wider and narrower-margin excisions in those with T1a melanoma by critical areas of the body.
