Summary
Prophylactic central neck dissection in papillary thyroid cancer is not guided by conventional risk factors. However, it significantly increases radioactive iodine treatment likelihood, indicating a need for standardized protocols.
Area of Science:
- Oncology
- Surgical Oncology
- Endocrinology
Background:
- Indications for prophylactic central neck dissection (pCND) in papillary thyroid cancer (PTC) are debated.
- The impact of lymph node (LN) metastasis identification on radioactive iodine (RAI) treatment decisions is unclear.
Purpose of the Study:
- To identify indications for performing pCND in PTC.
- To determine factors predicting the use of adjuvant RAI after thyroidectomy.
Main Methods:
- Population-based cross-sectional analysis of 594 patients undergoing total thyroidectomy +/- CND.
- Multivariate model to identify pCND indications and RAI predictors.
Main Results:
- Conventional risk factors did not predict pCND; only clinically suspicious lymphadenopathy led to CND.
- pCND identified LN metastases in 39% of cases, upstaging 87 patients.
- LN metastasis was the strongest predictor for RAI (OR=5.9), tumor size a modest predictor (OR=1.8).
Conclusions:
- pCND decisions appear based on surgeon preference rather than conventional risk factors.
- pCND upstages patients and significantly increases RAI likelihood (6-fold).
- A unified approach to pCND and RAI administration is needed.
