Identifying invasive lung adenocarcinomas manifesting as part-solid nodules by measuring the size of multiple solid portions and maximum solid portions.

ABSTRACT:

Background

Previous studies have reported that the presence of solid components in part-solid nodules (PSNs) may be closely related to the degree of tumor invasion, and have proposed that the consolidation/tumor ratio (CTR) on imaging is an important criterion for determining pathological invasiveness. However, currently, there is no common assessment standard for PSNs with multifocal solid portions. This study sought to provide valuable suggestions for identifying invasive adenocarcinomas (IACs) manifesting as PSNs based on different quantitative measurement methods, including the single largest solid portion, the solid proportion, and the sum of multiple solid portion measurements.

Methods

The data of 186 patients with surgically resected PSNs at Zhengzhou University Peopl
