Summary
Sentinel node radiolocalization using technetium-99m sulfur colloid is feasible for staging head and neck squamous cell carcinoma. This technique accurately identifies sentinel lymph nodes, potentially aiding in the detection of regional micrometastatic disease.
Area of Science:
- Oncology
- Nuclear Medicine
- Surgical Oncology
Background:
- Head and neck squamous cell carcinoma (HNSCC) staging requires accurate assessment of regional lymph node involvement.
- Sentinel lymph node biopsy is a minimally invasive technique to identify the first lymph node(s) draining a tumor site.
Observation:
- This prospective study evaluated sentinel node radiolocalization in eight patients with N0 HNSCC.
- Technetium-99m sulfur colloid was injected peritumorally, and sentinel nodes were identified using a gamma probe.
- Complete neck dissections were performed for histological comparison.
Findings:
- Sentinel node radiolocalization successfully identified two or more sentinel lymph nodes in all eight cases.
- In one patient, sentinel nodes identified micrometastatic disease.
- No cases showed a negative sentinel node with positive nonsentinel nodes.
Implications:
- Sentinel node radiolocalization is a feasible technique for N0 HNSCC.
- This method may reduce the morbidity, time, and cost associated with regional lymph node management.
- Further experience is needed to establish the definitive role of sentinel node biopsy in HNSCC management.
