Objectives We aimed to investigate the differences in clinical features between pulmonary embolism (PE) patients concomitant with lung cancer and without lung cancer (LC) and gain further understanding of the impact of lung cancer on pulmonary embolism. Methods This retrospective study sampled 114 patients diagnosed with pulmonary embolism from January 2017 to April 2021 in the First Affiliated Hospital of Soochow University. The patients were categorized into the LC group (n = 22) or non-LC group (n = 92). Myocardial injury, coagulation and blood cell parameters, along with imaging findings, were analyzed for the two groups. The primary outcome measure was the 90-day mortality. Results Of the 114 patients with pulmonary embolism in the present study, the 90 intermediate-risk patients were enrolled for further investigations. Compared to the non-LC group, patients in the LC group had milder myocardial injury, more severe coagulation function disorder, a higher incidence of central PE and a smaller change in diameter of the main pulmonary artery. We found that the occurrence of pericardial effusion created the risk of lung cancer in patients with pulmonary embolism, but there was no increase in the 90-day mortality for non-LC group versus LC group. Conclusion Intermediate risk PE patients concomitant with lung cancer seem to be more likely to present specific clinical features, accordingly, clinicians must pay great attention to PE patients concomitant with lung cancer and implement effective treatments to simultaneously manage the two conditions.
