Background: little has been known about the IJV invasion by untreated papillary thyroid carcinoma (PTC).<br>Objective: to clarify the clinical features of the IJV invasion by PTC.<br>Methods: a chart review on the cases of previously untreated PTC which were treated by curative surgery during the period from April 2005 through March 2011 at Kyoto Medical Center.<br>Results: a total of 175 cases were adopted, among which the IJV was resected partially or circumferentially in 9 sides of 8 cases (“resected group”). In all the affected sides, invasion was non-transmural. A metastatic node in the lateral compartment was the responsible lesion in 8 sides. The responsible node was located in the level IV region in 5 sides. The IJV was resected circumferentially in 7 sides and partially in 2. In the comparison between the resected group and the non-resected group, adjacent organ invasion either by primary or metastatic tumor, intraglandular multicentricity, tall cell variant of histology, and nodal metastasis in the lateral compartment were shown to be statistically more frequent in the resected group (p<0.05).<br>Conclusion: Most of the IJV invasion by PTC is non-transmural in nature and is caused by a metastatic node in the lateral cervical compartment, especially in the lower part.
