Results

Of the 319 included patients, 116 were categorized into the high-ratio group and 203 into the low-ratio group. After propensity score matching, OS was significantly worse in the high-ratio group than in the low-ratio group (5-year OS: 89.4% vs. 96.2%; P = 0.006). The high-ratio group had a significantly higher non-lung cancer-related death incidence than the low-ratio group (P = 0.01).

Baseline Characteristics

Before propensity score matching, PA/A high ratio group had significantly more patients with interstitial changes and higher BMI.
After propensity score matching, all relevant variables except for the pathological stage (standardized mean difference [SMD] = 0.12) were confirmed to be well-matched.

Participant flow

In total, 600 patients underwent complete resection of pathological Tis-1cN0M0 NSCLC between January 2013 and December 2018. Among the 600 patients, 319 were eligible, after excluding those with simultaneous or metachronous cancers and those with a history of thoracic surgery. Of the 319 included patients, 116 were categorized into the high-ratio group and 203 into the low-ratio group. The number of patients who underwent echocardiography as a preoperative assessment was 155.

Adverse events

Not applicable

Outcome measures

OS was significantly worse in the high-ratio group than in the low-ratio group.
In the high-ratio group, 6 lung cancer-related deaths and 14 other causes of death were recorded, whereas in the low-ratio group, 3 lung cancer-related deaths and 3 other causes of death occurred. Although the cumulative incidence of lung cancer did not differ between the two study groups, the incidence of competing causes of death was significantly higher in the high-ratio group than in the low-ratio group.
