Metastasectomy in cutaneous melanoma

Area of Science:

• Oncology
• Surgical Oncology
• Melanoma Research

Background:

• Metastasectomy is a key intervention for malignant melanoma, historically linked to high survival rates.
• Complete pathologic response is achievable with metastasectomy, often within a short hospital stay.
• Curative resection is feasible only for a select group of patients with specific metastatic patterns.

Purpose of the Study:

• To evaluate the role and outcomes of metastasectomy in malignant melanoma.
• To identify patient subgroups who benefit from curative resection of distant metastases.
• To assess the palliative role of metastasectomy in managing melanoma complications.

Main Methods:

• Review of historical data and literature on metastasectomy outcomes in malignant melanoma.
• Analysis of patient characteristics, including disease-free interval and preoperative imaging (PET/CT, MRI).
• Distinction between complete resection and debulking strategies for metastatic melanoma.

Main Results:

• Metastasectomy is the sole curative treatment for malignant melanoma with complete pathologic response.
• Long-term survival is associated with complete resection of all metastases; debulking is ineffective.
• Metastasectomy provides significant palliation for gastrointestinal bleeding or obstruction caused by melanoma.

Conclusions:

• Metastasectomy is vital for select malignant melanoma patients with oligometastatic disease.
• Complete resection of all metastases is mandatory for achieving long-term survival.
• Further research is needed to clarify the optimal timing and sequencing of metastasectomy within multimodal melanoma treatment.
