Filter by:The goal of this observational clinical trial is to establish a new method for differentiating benign and malignant pulmonary nodules by peripheral blood detection in patients with pulmonary nodules (<3cm). The main questions it aims to answer is: How to combine blood metabolomic mass spectrometry detection and artificial intelligence image analysis to establish a new model for differentiating benign and malignant pulmonary nodules. Participants will be asked provide 4 mL peripheral blood for the test.
The prevention and treatment of lung nodules involves many fields in preventive medicine and clinical medicine. A nodule is a growth or lump that may be malignant (cancer) or benign (not cancer). This study is aim to investigate the chemopreventive effect of limonene in inhibiting the occurrence/progression of ground glass pulmonary nodules. It is expected that limonene can be used as a safe and effective chemopreventive agent for preventing the development/progress of pulmonary nodules as well as expanding the indications of limonene.
Localization is the key for successful excision of small target nodules under thoracoscopy, but the procedure also brings risks to patients. However, the criteria is still unclear. The investigators will validate the prediction model produced by institutional retrospective analysis in the prospective cohort.
The broad goals of this study is to identify changes in genomic landscape during transition from stage 0 to stage 1 lung cancer. This study intends to determine whether diagnostic biomarkers measured in minimally invasive biospecimens are able to correlate molecular, clinical and imaging features to distinguish malignant from benign pulmonary nodules. The diagnostic markers once validated can be used as broad screening tools for lung cancer.
This study through the detection of EGFR、ALK、ROS1、KRAS、HER2、BARF、NTRG1 seven ctDNA and exosome RNA in the blood and alveolar lavage of lung nodules patients and heavy smoking healthy population. If the results of ctDNA test is positive, the target nodule is malignant; if the reaults of ctDNA teste is negatie but exocome RNA is positive, the target nodule is also malignant. If the results of both tests are negtive, the target nodule is recognized as benign. The purpose is study the sensitivity, specificity and diagnostic accuracy of ctDNA and exosome combined detection in the identification of benign and malignant pulmonary nodules. Besides, the diagnostic efficacy of different specimens including blood and alveolar lavage in the identification of benign and malignant pulmonary nodules is also studied.
