Summary
Delayed sentinel lymph node biopsy (SLNB) after melanoma wide local excision (WLE) may show varied results. Comparing pre- and post-WLE lymphoscintigraphy reveals changes in sentinel lymph node location and number, impacting staging accuracy.
Area of Science:
- Oncology
- Surgical Oncology
- Dermatology
Background:
- Sentinel lymph node biopsy (SLNB) is crucial for melanoma staging, typically done with wide local excision (WLE).
- The accuracy of delayed lymphatic mapping after prior WLE for melanoma is not well-established.
- Lymphatic mapping guides the identification of sentinel lymph nodes for metastasis assessment.
