Role for radiation therapy in melanoma

Area of Science:

• Oncology
• Radiation Oncology
• Dermatology

Background:

• Melanoma is often considered radioresistant.
• Radiation therapy (RT) is utilized in definitive, adjuvant, and palliative contexts for melanoma.
• Definitive RT is typically reserved for inoperable patients.

Purpose of the Study:

• To review the current role and potential of radiation therapy in melanoma treatment.
• To highlight the effectiveness of RT in palliative care for metastatic melanoma.
• To discuss the controversial yet promising application of adjuvant RT.

Main Methods:

• Literature review of clinical trials and studies on radiation therapy for melanoma.
• Analysis of RT's efficacy in different treatment settings (definitive, adjuvant, palliative).
• Evaluation of RT's role in combination with systemic therapies like immunotherapy.

Main Results:

• RT is effective for symptom palliation in metastatic melanoma.
• Adjuvant RT after lymphadenectomy can prevent local/regional recurrence in node-positive melanoma, though its use is underutilized.
• RT remains a valid option across various melanoma treatment scenarios.

Conclusions:

• Radiation therapy is a valuable treatment modality for melanoma, especially for palliation.
• The role of adjuvant RT warrants further investigation and potential wider adoption.
• Combining RT with novel systemic treatments like immunotherapy presents a promising future direction.
