Abstract
Introduction: Previous studies have reported inconsistent findings regarding the associationbetween ALK and ROS1 rearrangements in lung cancer and thromboembolic risk. This retrospective study aimed to investigate this association in advanced lung adenocarcinoma patients with ALK, ROS1, RET rearrangements, and EGFR mutations.
Materials and methods: We retrospectively collected information on patients with advanced lung adenocarcinoma in the First Affiliated Hospital of Zhejiang University School of Medicine from January 2013 to March 2021. All patients with confirmed ALK, ROS1, or RET rearrangements, as well as a comparison cohort of those with EGFR mutation, were included. Clinical characteristics were analyzed, and the association between driver genes and TE risks was analyzed using competing risk and logistic regression.
Results: A total of 546 patients were included in the study. Among them, those with ROS1 rearrangements exhibited the highest cumulative incidence of thromboembolic events (TEs), reaching 17.5% ± 0.2% during the peri-diagnostic period (within 6 months following diagnosis). Regardless of the entire follow-up or the peri-diagnostic period, ROS1 rearrangements were significantly associated with an increased risk of TEs. Multivariate analysis revealed ROS1 rearrangements, the number of comorbidities, the size of mediastinal lymph nodes, and elevated C-reactive protein (CRP) levels as TE risk factors during the peri-diagnostic period. Throughout the follow-up period, ROS1 rearrangements and hypertension were independent TE risk factors. In addition, the development of TE significantly affected the overall survival of patients with EGFR mutations.
Conclusion: ROS1 rearrangements were significantly associated with an increased risk of TE.
期刊介绍：
Thoracic Cancer aims to facilitate international collaboration and exchange of comprehensive and cutting-edge information on basic, translational, and applied clinical research in lung cancer, esophageal cancer, mediastinal cancer, breast cancer and other thoracic malignancies. Prevention, treatment and research relevant to Asia-Pacific is a focus area, but submissions from all regions are welcomed. The editors encourage contributions relevant to prevention, general thoracic surgery, medical oncology, radiology, radiation medicine, pathology, basic cancer research, as well as epidemiological and translational studies in thoracic cancer. Thoracic Cancer is the official publication of the Chinese Society of Lung Cancer, International Chinese Society of Thoracic Surgery and is endorsed by the Korean Association for the Study of Lung Cancer and the Hong Kong Cancer Therapy Society.
The Journal publishes a range of article types including: Editorials, Invited Reviews, Mini Reviews, Original Articles, Clinical Guidelines, Technological Notes, Imaging in thoracic cancer, Meeting Reports, Case Reports, Letters to the Editor, Commentaries, and Brief Reports.
