Malignant melanoma

Last edited: 4/10/2026

Overview

Malignant melanoma is a common cancer, particularly in South Africa, associated with significant mortality, often affecting individuals at a younger age 2. Early detection is a critical factor in its management, though effective prevention strategies have not yet been conclusively achieved 2.

Diagnosis

  • All suspected melanoma patients must be confirmed histologically and resected 1.
  • Early detection is primarily based on changes in color, diameter, elevation, border irregularity, asymmetry, or a lesion that differs from other nevi 2.
  • Clinicians should be trained in the recognition of early melanoma 2.
  • If there is doubt about a lesion, the patient should be referred for specialist opinion or a biopsy should be undertaken 2.
  • Sentinel node biopsy is recommended for tumors over 1 mm or for smaller tumors with high-risk factors 1.
  • Individuals at high risk of melanoma should be offered a surveillance program 2.
  • Management

  • Adjuvant therapy with interferon may be offered for patients with high-risk melanoma, and radiotherapy can be added in selected cases 1.
  • Treatment for metastatic melanoma is guided by BRAF mutational status 1.
  • For BRAF wild-type metastatic melanoma, anti-PD1 containing therapy is recommended 1.
  • For BRAF mutated metastatic melanoma, BRAF/MEK inhibitors or anti-PD1 containing therapy are options 1.
  • Follow-up for melanoma patients should include dermatologic and physical examinations for up to 10 years 1.
  • Key Recommendations

  • All suspected melanoma patients must be confirmed histologically and resected 1. (Evidence: Strong)
  • Sentinel node biopsy must be performed for tumors over 1 mm or for smaller tumors with high-risk factors 1. (Evidence: Strong)
  • Treatment for metastatic melanoma is guided by BRAF mutational status; BRAF wild-type patients must receive anti-PD1 containing therapy, while BRAF mutated patients should receive BRAF/MEK inhibitors or anti-PD1 containing therapy 1. (Evidence: Strong)
  • Melanoma patients should undergo dermatologic and physical examinations for follow-up for up to 10 years 1. (Evidence: Moderate)
  • Clinicians should be trained in the recognition of early melanoma, and high-risk individuals should be offered a surveillance program 2. (Evidence: Expert opinion)
