Summary
Sentinel lymph node biopsy (SLNB) is useful for staging papillary thyroid cancer (PTC), particularly in men. This study assessed SLNB in micro-PTC patients without lymphadenopathy, finding it helpful for nodal staging and disease clearance.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Sentinel lymph node biopsy (SLNB) is a debated technique in thyroid carcinoma.
- Papillary thyroid carcinoma (PTC) management requires accurate nodal staging.
Purpose of the Study:
- To evaluate the utility of SLNB in micro-PTC patients without clinical lymphadenopathy.
- To assess SLNB's effectiveness in determining nodal status for early-stage thyroid cancer.
Main Methods:
- Retrospective analysis of 114 micro-PTC patients undergoing SLNB.
- SLNB followed by thyroidectomy and central neck dissection.
Main Results:
- Sentinel lymph node identification rate was 98.2% with a 11.3% false-negative rate.
- Lymph node metastasis was more common in men.
- Higher SLN detection correlated with increased metastasis probability.
Conclusions:
- SLNB can aid in staging nodal status for PTC, especially in male patients.
- It is valuable for identifying occult metastases and guiding treatment decisions.
