Background: Papillary thyroid cancer (PTC) patients with clinical negative central lymph nodes (cN0), the use of prophylactic central lymph node dissection remains controversial. Patients with cN0 disease receive contralateral central lymph node metastasis (CCLNM) 3.88–30.63% of cases. Therefore, the present study aimed to obtain evidence for CCLNM risk factors in unilateral cN0 PTC.
Materials and methods: Relevant studies were searched in the PubMed, SCIE, and Wanfang databases up to 31 Oct 2019. The included patients had undergone lobectomy or total thyroidectomy with bilateral central lymph node dissection and were diagnosed pathologically with PTC.
Results: Thirteen studies comprising 2449 patients were included. The factors associated with increased CCLNM risk in cN0 unilateral PTC were: age < 45 years (odds ratio (OR) = 1.89, 95% confidence interval (CI) = 1.43–2.49, P < 0.00001), male sex (OR = 1.67, 95% CI = 1.24–2.24, P = 0.0007), extrathyroidal extension (OR = 1.63; 95% CI = 1.17-2.28; P = 0.004), tumor size ≥ 1 cm (OR = 2.63, 95% CI 1.85–3.74, P < 0.00001), lymphovascular invasion (OR = 4.27, 95% CI =2.47-7.37, P < 0.00001) and ipsilateral CLNM (OR = 11.42, 95% CI = 5.25-24.86, P < 0.00001). However, no association was found for capsular invasion, multifocality and Hashimoto thyroiditis.
Conclusion: The study identified that age <45 years, tumor ≥1 cm, male sex, lymphovascular invasion, extrathyroidal extension and ipsilateral CLNM are related to CCLNM in CN0 PTC. These factors should influence the use of prophylactic central lymph node dissection in these patients.
