NCT07312682
This retrospective single-center study investigates whether four-dimensional CT (4DCT)-based lung ventilation imaging can guide functional lung avoidance radiotherapy (FLAR) for patients with primary lung cancer. Ventilation maps generated from planning 4DCT are used to identify well-ventilated lung regions, enabling paired comparison between functional lung avoidance radiotherapy plans and conventional anatomic radiotherapy plans. The study aims to assess whether incorporating functional lung information into radiotherapy planning can reduce radiation exposure to well-ventilated lung while maintaining adequate tumor coverage, and to explore its relationship with radiation-induced lung injury. All analyses are based on existing clinical imaging, treatment planning data, and follow-up records. No additional interventions, imaging, or procedures are performed as part of this study.
NCT06557343
Patients with signs of radiation induced lung inflammation, who are referred for a clinical bronchoscopy for investigation, will have a sample sent for single cell sequencing. This is a novel technique which allows for identification of which cells are present and what they are doing. This hopes to better understand radiation pneumonitis, a dose-limiting toxicity in cancer treatment which can be highly morbid and even fatal.
NCT06861179
The objectives of this clinical trial were to determine the radioprotective effects and underlying biological mechanisms of Phellinus igniarius and its active components during radiotherapy in patients with thoracic malignant tumors. The study group was given the formulation of Compound Phellinus igniarius decoction daily during radiotherapy, 150ml bid until the end of radiotherapy; The control group only received standard dose radiotherapy without the formulation of Compound Phellinus igniarius decoction intervention. The baseline differences between the two groups were compared, including gender, smoking history, body mass index (BMI), pathological classification, median age of onset, inflammatory factors, tumor markers, TNM stage, KPS score, fatigue score, incidence and grade of radiation pneumonitis, incidence of other radiotherapy-related adverse reactions, and average radiation dose.
NCT06069115
Prospective cohort research to study the state of oxygen metabolism, reserve capabilities of cardiovascular and respiratory systems in patients with breast cancer to create a program of prevention and rehabilitation of lung damage in the process of complex treatment of the disease. The aim of the study is to study the dynamics of oxygen metabolism and reserve capabilities of cardiovascular and respiratory systems in the process of complex treatment of breast neoplasias. Objectives of the study: 1. Explore the dynamics of pulmonary ventilation and gas exchange disorders in patients with breast cancer in the course of radiation therapy 2. Establish an algorithm for risk stratification of post-radiation disorders of pulmonary ventilation and gas exchange in patients with breast cancer. 3. Analyze the prognostic significance of cardiopulmonary exercise testing in assessing the cardiotoxic effect of chemo- and radiation therapy in patients with breast cancer. 4. Analyze the influence of post-radiation disorders of pulmonary ventilation and gas exchange on the quality of life and psycho-emotional status of patients with breast cancer. 5. Develop a fundamental basis for the program of prevention and rehabilitation of post-radiation lung damage in patients with breast neoplasias based on the study of individual parameters of oxygen metabolism and reserve capabilities of cardiovascular and respiratory systems. All participants go through 5-week radiation therapy in standard protocol, will have investigation of their lung functioning by spirography and assessment of pulmonary diffusion capacity, cardiopulmonary stress tests and CT-scan on the lungs before radiotherapy course. Researchers will analyze such parameters as stage of the disease, surgery type, all patient's medications, complications, nutritional status, psychological status.
NCT06079931
Radiation pneumonitis (RP) is a common complication of radiotherapy for thoracic tumors, and the incidence rate of grade 2 or above RP is 20% -40%; The use of antibiotics after secondary bacterial infection due to radiation pneumonia or the use of systemic glucocorticoids for radiation pneumonia itself have significant adverse effects on the survival of NSCLC patients. At present, FDA has not approved drugs to prevent the occurrence of radiation pneumonia. traditional Chinese patent Babaodan (BBD) capsule has the effect of controlling macrophages to produce proinflammatory cytokines, such as significantly inhibiting the release of IL-6. Through prospective research, this study evaluates the incidence of symptomatic pneumonia (G ≥ 2) in the treatment of locally advanced non-small cell lung cancer with BBD combined with concurrent radiotherapy and chemotherapy.
NCT03796364
To verify the efficacy and safety of endostatin in the treatment of SRILI（symptomatic radiation-induced lung injury） and fibrosis. The results of this study are expected to be a new clinical strategy for the treatment of radiation pneumonia and fibrosis.
NCT04863027
This is a prospective observational study aiming: 1) To quantify lung function using perfusion dual energy computed tomography (DECT) and use this information at the time of treatment planning with preferential sparing of functional lung parenchymal 2) to validate results of lung function obtained using DECT with lung perfusion scintigraphy results, the current standard method; 4) to compare dosimetry of whole lungs vs. functional lungs in patients treated with either stereotactic body radiotherapy (SBRT) for early stage lung cancer or conventional radiotherapy for locally advanced lung cancer and 5) to evaluate lung function 6, 12 and 24 months post-radiotherapy with both perfusion DECT and pulmonary function tests and compare radiation dose-map to functional lung-map.
NCT00155909
A prospective observational study to evaluate clinical, dosimetrical, functional, and biological factors in predicting radiation pneumonitis.
