Trial Comparing CPDMA Versus Standard Breadloafing in WLE Specimens of Stage 1-II Cutaneous Melanoma

The primary goal of this clinical trial is to is to compare the rate of positive peripheral margins in wide local excision (WLE) performed to allow for comprehensive peripheral and deep margin assessment (CPDMA) assessment versus WLE performed with the intent of standard breadloafing of stage I-II cutaneous melanoma specimens. Secondary aims are to compare local recurrence at 1 and 2 years, the rate of re-excision due to positive margins, pathology turnaround time, pathology resource utilization, and cost per case between the two assessment methods. The main questions it aims to answer are: * Does WLE performed to allow for CPDMA have a higher rate of positive peripheral margins than wide local excision performed with the intent of standard breadloafing? * Will more complete positive margin detection support more appropriate re-excision and lower local recurrence over two years? * Does CPDMA require greater pathology resource utilization and longer turnaround time than breadloafing? Researchers will compare standard breadloafing (control) arm to CPDMA (experimental) arm. Participants will: * Undergo WLE. * Attend a follow-up visit at 4 months.

Melanoma Margins Trial-II: 1cm v 2cm Wide Surgical Excision Margins for AJCC Stage II Primary Cutaneous Melanoma

Patients with a primary invasive melanoma are recommended to undergo excision of the primary lesion with a wide margin. There is evidence that less radical margins of excision may be just as safe. This is a randomised controlled trial of 1 cm versus 2 cm margin of excision of the primary lesion for adult patients with stage II primary invasive cutaneous melanomas (AJCC 8th edition) to determine differences in disease-free survival. A reduction in margins is expected to improve patient quality of life.
