Active clinical trials for "Radiation Pneumonitis"

The purpose of this study is to assess the safety and efficacy of pirfenidone capsules to treat grade 2 or above radiation-induced lung injury patients.

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.

Lung cancer [LC] is the leading cause of cancer death worldwide. The standard treatment of locally advanced lung cancer unresectable or marginally resectable is combination therapy with radical or preoperative chemoradiation. The local control rates and survival with this treatment modality have increased by more than 30%. Radiotherapy [RT] with technical molded 3D [3D-CRT, Three-Dimensional Conformal Radiation Therapy] or IMRT [intensity-modulated radiation therapy] has allowed that the total dose of radiation has increased which leads to a direct benefit on the results treatment. Between 17-30% of patients are susceptible to pneumonitis due to radiation [NR]. This complication may appear at the end of the RT or up to 6 months after the treatment. In severe cases, mortality can reach 50%. It's well known that in various diseases, functional abnormalities precede the clinical manifestations. The degree of pulmonary failure secondary to RT is measured following the standards of the Radiation Therapy Oncology Group who ranks in degrees [0 to 4]. Not precisely known factors that influence the development of NR.

The goal of this clinical research study is to learn if the level of nitric oxide you breathe out may relate to the amount of breathing complications that you may experience due to radiation treatment.

This project will test the effect of nicorandil to mitigate the lung damage that can occur as a side effect of radiation therapy for lung cancer. Thousands of veterans develop lung cancer every year, and are treated by radiation therapy. Studies of lung radiation injury in laboratory animals show that with nicorandil, investigators can significantly reduce the severity of lung fibrosis and heart toxicity.1,2 Nicorandil is FDA approved and in common use for treatment of angina. These studies will advance that work to human use. Successful mitigation of lung radiation damage and heart toxicity will improve the quality of life in veterans and non-veterans who are treated for lung cancer by radiation, and may also improve cure rates of radiation therapy for lung cancer.

The purpose of this clinical trial is to evaluate the safety when HL301 is administered to unresectable non-small cell lung cancer patients who receive chemoradiotherapy with Paclitaxel and Carboplatin and to search for a clinically appropriate dose by evaluating the efficacy by comparing the radiation pneumonia incidence rate with the control group.

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.

Although recent global trends indicate reduced postoperative mortality after esophagectomy, major morbidity, in particular pulmonary, remains high, with considerable health and economic costs. In a recent modern international collaborative series of 2704 patients from high-volume centers, with an approximate equal mix of open and minimally invasive approaches, respiratory complications were evident in 28% of patients, pneumonia in 15%, and respiratory failure in 7%.1 In other series, respiratory failure is reported in up to 15% of patients and is the most common cause of mortality. Prediction of risk and prevention of respiratory morbidity is therefore of considerable importance, and in this context baseline assessment of respiratory physiology compliments clinical assessment, history and enhanced recovery pathways representing key elements of current patient management. In this study, which will include all prospective patients with locally advanced esophageal cancer treated at a National Center, pulmonary function will be systematically measured before and after neoadjuvant therapy. The investigators seek to evaluate the incidence of radiation induced lung injury (RILI), as well as subclinical changes in pulmonary physiology that may be linked to postoperative complications, and quality-of-life in survivorship, and to compare cohorts who received radiation therapy or chemotherapy alone, preoperatively.

A prospective observational study to evaluate clinical, dosimetrical, functional, and biological factors in predicting radiation pneumonitis.
