Summary
Central lymph node metastases are common in papillary thyroid microcarcinoma (PTMC). Male sex and larger tumors predict ipsilateral spread, while ipsilateral positivity predicts contralateral spread in node-negative patients.
Area of Science:
- Endocrinology
- Surgical Oncology
- Head and Neck Cancer Research
Background:
- Indications for prophylactic central lymph node (CLN) dissection in clinically node-negative papillary thyroid microcarcinoma (PTMC) remain unclear.
- Optimal extent of CLN dissection for PTMC requires further investigation.
Purpose of the Study:
- To analyze the frequency, patterns, and predictive factors of CLN metastases in clinically node-negative patients with unilateral PTMC.
- To determine risk factors associated with CLN metastasis in PTMC.
Main Methods:
- Retrospective analysis of 86 patients with unilateral PTMC and clinically node-negative neck.
- Evaluation of clinicopathological factors including age, sex, tumor size, and invasion.
- All patients underwent total thyroidectomy and CLN dissection.
Main Results:
- 31% of patients (27/86) had CLN metastases, with 18 ipsilateral and 9 bilateral.
- Male sex and tumor size >0.5 cm predicted ipsilateral CLN metastases.
- Ipsilateral nodal positivity was the sole significant predictor of contralateral CLN metastases.
Conclusions:
- Central lymph node metastases are relatively common in PTMC.
- Risk stratification for CLN dissection in PTMC is crucial.
- Further research needed to refine surgical management guidelines.
