Cardiac Substructure Radiation Dose and Early Clinical Monitoring of Stage N2-3 Non-Small Cell Lung Cancer
2022年2月19日 更新者：Guizhou Medical University
Cardiac Substructure Radiation Dose and Early Clinical Monitoring of Stage N2-3 Non-Small Cell Lung Cancer Treated With Conventional Radiotherapy
Calculating which cardiac substructure accepting with the highest radiation dose by conventional radiotherapy, then to investigate the relationship between the changes of global longitudinal strain or cardiac magnetic resonance imaging and cardiac biomarkers and the certain cardiac substructure for stage N2-3 non-small cell lung cancer
研究概览
详细说明
All patients receive intensity-modulated radiotherapy (IMRT).
The prescription dose of PTV is 60-70Gy，Troponin I, troponin T, hypersensitive troponin, brain natriuretic peptide and NT-proBNP are detected before radiotherapy, at the end of radiotherapy (day 15), at the end of radiotherapy and at 1 month after radiotherapy.
Echocardiography was performed before radiotherapy, in the middle of radiotherapy (day 15) and at the end of radiotherapy to obtain global longitudinal strain value.
Cardiac magnetic resonance imaging is used to measure the blood flow of the anterior descending coronary artery before and at the end of radiotherapy.

Patients with NSCLC
all stage N2-3 non-small cell lung cancer patients receive intensity-modulated radiotherapy (IMRT).
The prescription dose of PTV is 60-70Gy.
|
Troponin I, troponin T, hypersensitive troponin, brain natriuretic peptide and NT-proBNP are detected for cardiac biomarkers;echocardiography and cardiac magnetic resonance imaging are used to measure the functions of heart and vessels.
