  • Title: Central lymph node metastases in unilateral papillary thyroid microcarcinoma.
    Author: Lim YC, Choi EC, Yoon YH, Kim EH, Koo BS.
    Journal: Br J Surg; 2009 Mar; 96(3):253-7. PubMed ID: 19224514.
    Abstract:
    BACKGROUND: The indications for and appropriate extent of prophylactic central lymph node (CLN) dissection for clinically node-negative patients with unilateral papillary thyroid microcarcinoma (PTMC) are unknown. METHODS: The frequency, patterns and predictive factors for CLN metastases in 86 patients with unilateral PTMC and a clinically node-negative neck were analysed with respect to age and sex; metastasis, age, completeness, invasiveness, size (MACIS) score; tumour size; number and location of tumours; presence of ipsilateral CLN metastases; and presence of lymphovascular or capsular invasion. All patients underwent total thyroidectomy and CLN dissection. RESULTS: Twenty-seven (31 per cent) of 86 patients had metastatic CLNs: 18 ipsilateral and nine bilateral. Univariable analysis suggested male sex and tumour size greater than 0.5 cm to be significant factors in predicting ipsilateral CLN metastases. Only ipsilateral nodal positivity was a significant predictor of contralateral CLN metastases in multivariable analysis (P = 0.007). CONCLUSION: CLN metastases are relatively common in PTMC.
