Risk factors for central lymph node metastases in patients with cN0 papillary microcarcinoma: An analysis of 306 patients at a single institution

  • Background: Papillary microcarcinoma (PMC) of the thyroid is defined as papillary thyroid carcinoma measuring ?1 cm, account for most of the increased incidence. Presence of lymph node metastases associated with an increased risk of local recurrence, but prophylactic central neck node dissection for PMC is controversial. The purposes of our study is to detect the predictive factors for central lymph node metastases (CLNM) in patients with cN0 PMC.

    Methods: We retrospectively assessed the clinicopathological characteristics of 306 patients with cN0 PMC operated at our hospital between March 1, 2017 and December 31, 2018, all underwent thyroid lobectomy or total thyroidectomy with unilateral or bilateral prophylactic central neck dissection. The relationship between CLN metastases and clinicopathologic features of PMC were analyzed

    Results: The incidence of CLNMs in cN0 PMC patients was 30.4% (93/306). Multivariate logistic regression showed male gender
