Sublobectomy versus lobectomy for peripheral small-sized pulmonary mucinous adenocarcinoma.

ABSTRACT:

Background

Pulmonary mucinous adenocarcinoma (PMA), a rare type of adenocarcinoma, remains controversial in terms of its associated prognosis. We conducted this study to compare the oncological outcomes of lobectomy and sublobectomy for peripheral small-sized PMA.

Methods

This retrospective observational study included all patients with peripheral small-sized (≤2 cm) clinical stage IA1-A2 PMA who underwent lobectomy or sublobectomy (with margin distances ≥2 cm or greater than tumor diameter) between January 2015 and December 2018. Recurrence-free survival (RFS) and overall survival (OS) were compared between the lobectomy and sublobectomy groups with Kaplan-Meier curves and log-rank tests.

Results

This study examined 279 patients, with 176 cases in the lobectomy group
