Epidemiology of Abdominal Aortic Aneurysm With Concomitant Primary Lung Cancer

1. research purpose： This study collected detailed basic information, lifestyle habits, past medical history, and laboratory indicators from 2000-3000 outpatient patients with primary lung cancer for data analysis and long-term follow-up. The study analyzed the related factors of lung cancer complicated with AAA, providing direct scientific evidence to better guide lung cancer patients in screening for AAA, identifying common high-risk factors for lung cancer patients complicated with AAA, providing clinical guidance for the prevention of AAA, and reducing the risk of AAA rupture. The research results are of great significance for the subsequent treatment and prognosis of lung cancer patients, as well as improving the long-term survival rate of lung cancer patients. They will also provide scientific basis and clinical guidance for the screening and prevention of AAA in lung cancer patients. Early detection and treatment of AAA can reduce the risk of AAA rupture, greatly improve the prognosis of lung cancer patients with AAA, and enhance their quality of life.
2. research population： The research subjects are patients diagnosed with primary lung cancer at the Third Affiliated Hospital of Kunming Medical University and the First Affiliated Hospital of Kunming Medical University from 1st October 2022 to 30 st April 2025. The expected sample size is about 2000 people, and the age of patients is 20-90 years old. Collect detailed epidemiological data and long-term follow-up data, conduct statistical analysis, and conduct epidemiological investigations.
