Segmentectomy for non-peripheral and peripheral small-sized non-small-cell lung cancer.

ABSTRACT:

Objectives

To compare the oncological outcomes of segmentectomy for non-peripheral versus peripheral small-sized non-small-cell lung cancer (NSCLC).

Methods

This retrospective observational study included patients with clinical stage IA1-A2 NSCLC who underwent segmentectomy. Patients were separated based on tumour distance index (DI, which was calculated as the ratio of the distance from the entrance of the segmental bronchus to the proximal tumour margin to the distance to the lobar pleura along the same line): non-peripheral group (DI ≤ 2/3) and peripheral group (DI > 2/3). Disease-free survival (DFS) and overall survival were compared with log-rank tests.

Results

850 patients were included, comprising 274 in the non-peripheral group and 576 in the peripheral group.
