Summary
This summary is machine-generated.

Managing early-stage melanoma with negative lymph nodes is debated. Sentinel lymph node biopsy (SLNB) offers a minimally invasive alternative to elective lymph node dissection (ELND) or observation, potentially avoiding unnecessary procedures.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Dermatology

Background:

  • Management of clinically negative regional lymph nodes in early-stage melanoma remains controversial.
  • Elective lymph node dissection (ELND) aims to prevent metastasis spread, while therapeutic dissection (TLND) is reserved for recurrence.
  • The 'wait and watch' approach considers lymph node metastases as markers of disease progression.

Purpose of the Study:

  • To evaluate the efficacy of intraoperative lymphatic mapping and sentinel lymphadenectomy (LM/SL) as an alternative to traditional management strategies.
  • To assess the potential of LM/SL to identify early-stage melanoma spread to regional lymph nodes.
  • To determine if LM/SL can help avoid unnecessary complete lymph node dissections (CLND).

Main Methods:

  • Intraoperative lymphatic mapping and sentinel lymphadenectomy (LM/SL) technique.
  • Utilizes lymphoscintigraphy and vital blue dye to identify the sentinel lymph node (SN).
  • Pathological examination of the SN for metastases.

Main Results:

  • LM/SL allows identification of the SN in the regional basin.
  • Tumor-positive SNs indicate the need for complete lymph node dissection (CLND).
  • Tumor-negative SNs allow avoidance of CLND, reducing associated complications and costs.

Conclusions:

  • LM/SL is a minimally invasive procedure that has become a standard practice in melanoma management.
  • The technique's success relies on a learning phase and multidisciplinary cooperation.
  • Ongoing clinical trials are crucial to definitively establish LM/SL's role compared to ELND and observation.
