Phase III Trial Comparing 1cm and 2cm Surgical Excision Margins for Stage II Primary Cutaneous Melanoma Evaluating Disease-Free Survival and Quality of Life

What this Trial Is About

Researchers are studying patients with stage II primary invasive cutaneous melanoma to compare the effects of two different surgical excision margins 1cm versus 2cm. The goal is to determine if narrower margins are as safe as wider margins in preventing melanoma recurrence and if they can improve patients quality of life. This trial also looks at the impact of these excision sizes on health services and society. Participants will be randomly assigned to receive either a 1cm or 2cm wide local excision margin around the primary melanoma lesion. Both groups will undergo sentinel lymph node biopsy and may have reconstruction surgery if needed. The surgery must be done within 120 days of diagnosis and within 28 days of randomization. During the study, participants will be followed for up to 60 months to measure disease-free survival as the primary outcome. Additional assessments include local recurrence, distant disease-free survival, melanoma-specific and overall survival, quality of life questionnaires, neuropathic pain evaluations, adverse event monitoring, and health economic analysis. Follow-up questionnaires and safety checks will occur at multiple time points up to 24 months after surgery, with longer-term monitoring continuing up to 120 months.
