Predictive Value of Preoperative Peak Oxygen Uptake for Postoperative Pulmonary Complications in Lung Cancer Patients with Chronic Obstructive Pulmonary Disease: A Single-Center Retrospective Cohort Study.

ABSTRACT:

Introduction

The relationship between preoperative peak oxygen uptake/weight (VO₂/W) and postoperative pulmonary complications (PPC) in lobectomies, including video-assisted thoracoscopic surgery, remains unclear. Traditional pulmonary function tests are often unreliable in this group, necessitating alternative predictive methods. Therefore, this study aimed to clarify the predictive value of preoperative peak VO₂/W for PPC and explore factors related to PPC in lung cancer patients with chronic obstructive pulmonary disease (COPD).

Methods

This single-center retrospective cohort study included 40 patients with lung cancer complicated by COPD who underwent a preoperative cardiopulmonary exercise test between January 2017 and March 2024. Patients were div
