Abstract:

Objective

To investigate the clinicopathological features and risk factors of skip metastasis to the lateral compartment without central lymph node metastasis in papillary thyroid carcinoma (PTC).

Methods

The medical records of two hundred and fifty-nine patients with PTC who met inclusion criteria in Fujian Medical University Union Hospital from July 2015 to November 2018 were retrospectively analyzed for the risk factors of skip lateral lymph node metastasis.

Results

The frequency of skip lymph node metastasis was approximately 9.3% (24/259). Univariate analysis showed that the skip metastasis group showed a lower harvested central lymph node number (P=0.031). In addition, skip metastasis was significantly associated with primary tumor size <1 cm (P<0.001) and tumor location in the upper portion of the thyroid (P=0.012). Multivariate analysis showed that primary tumor size <1 cm (OR=5.934, P<0.001) and tumor location in the upper portion of the thyroid (OR=2.812, P=0.023) were the independent risk factors of skip metastasis.

Conclusion

Skip metastasis in PTC is more likely in patients with tumor size <1 cm and tumor location in the upper portion of the thyroid.
