For melanoma patients with a positive sentinel lymph node (SLN), observation is risky. Untreated microscopic nodal disease significantly worsens prognosis, necessitating complete lymph node dissection until further data emerge.

Area of Science:

  • Oncology
  • Dermatology
  • Surgical Pathology

Background:

  • Sentinel lymph node (SLN) biopsy is crucial for melanoma staging.
  • Microscopic nodal disease often progresses to macroscopic disease.
  • Current systemic treatments for advanced melanoma are largely ineffective.

Purpose of the Study:

  • To evaluate the risks of observation for melanoma patients with positive SLN.
  • To determine the optimal management strategy for positive SLN in melanoma.

Main Methods:

  • Review of clinical progression of microscopic nodal disease.
  • Analysis of prognostic implications of nodal status in melanoma patients.

Main Results:

  • Untreated microscopic nodal disease in melanoma patients has a high likelihood of progressing to macroscopic nodal disease.

  • Macroscopic nodal disease is associated with a worse prognosis.
  • Observation of positive SLN may lead to significantly worsened outcomes.

    • Conclusions:

    • Melanoma patients with a positive SLN by H&E analysis should undergo complete lymph node dissection.
    • Observation of positive SLN is not recommended due to high risk of progression and poor prognosis.
    • Further research is needed to refine management strategies, but current data support immediate dissection.
