Summary

Sentinel lymph node biopsy is a feasible procedure for cutaneous malignant melanoma, potentially avoiding extensive lymph node dissection. This method identifies the first draining lymph node, and if clear, suggests no further metastasis in the regional basin.

Area of Science:

  • Surgical Oncology
  • Dermatology
  • Pathology

Background:

  • Lymph node dissection in cutaneous malignant melanoma treatment remains controversial.
  • Sentinel lymph node biopsy (SLNB) offers a targeted approach to staging.
  • SLNB feasibility has been established in various solid malignancies.

Purpose of the Study:

  • To assess the feasibility of sentinel lymph node biopsy in patients with primary cutaneous melanoma.
  • To evaluate the diagnostic yield and procedural characteristics of SLNB for melanoma staging.

Main Methods:

  • A feasibility study involving patients with intermediate or high-risk primary cutaneous melanoma.
  • Identification and biopsy of the sentinel lymph node, defined as the first tumor-draining lymph node.
  • Histological examination of the sentinel lymph node to detect metastasis.

Main Results:

  • The sentinel lymph node biopsy procedure was successful in 38 out of 40 patients.
  • Metastasis was confirmed in the sentinel lymph node of nine patients.
  • The procedure duration ranged from five to 15 minutes.

Conclusions:

  • Sentinel lymph node biopsy is a feasible and rapid procedure for staging cutaneous malignant melanoma.
  • Positive sentinel lymph node findings indicate metastasis, guiding further treatment decisions.
  • Further prospective and randomized studies are warranted to confirm these findings.
