Filter by:The goal of this observational validation study is to determine the best implementation of fluoroscopic and CT ventilation imaging in patients having non-stereotactic ablative body radiotherapy (non-SABR) radiotherapy for stages II-IV lung cancer. The main questions it aims to answer are: - Assess the dosimetric variation in functional avoidance radiation therapy (RT) plans produced using these ventilation imaging techniques, - Establish a quality assurance procedure for functional lung avoidance radiation therapy, and - Evaluate the clinical acceptable thresholds for accuracy of the method. Participants will: Prior to radiation therapy treatment, patients will undergo: 1. A standard of care 4DCT scan for radiation therapy simulation, 2. Pulmonary Function Tests (PFT) 3. A 4D attenuation correction CT 4. Breath Hold Computed Tomography (BHCT) imaging where static end-inspiration and end-expiration BHCT scans will be acquired, 5. Nuclear medicine imaging where a Tc-99m MAA SPECT perfusion scan and a Galligas PET ventilation scan will be acquired, 6. Fluoroscopy where 1-breath cine-fluoroscope sequences will be acquired at five different angles across the chest, 7. A 4D Cone Beam Computed Tomography (4DCBCT) scan. 8. Scans in points 4 to 7 above will be repeated at the end of treatment. Individual participants provide their own internal control. Galligas PET ventilation images (control) are compared with ventilation images derived from additional scans (comparator) for each participant. Tc-99m MAA SPECT perfusion images (control) are compared with perfusion images derived from BHCT scans (comparator) for each patient. There will be no change to patient treatment and patients will be treated using a standard of care anatomical based treatment plan. The pre-treatment 4DCBCT scan is part of standard of care.
Immunotherapy have revolutionized the field of oncology, but response rates are low and all patients relapse, due to cellular and soluble immunosuppressive mechanisms. These immunosuppressive mechanisms will be better characterized and their involvement in therapeutic responses in non-small cell lung cancers (NSCLC). Indeed, large transcriptomic analysis of different subsets of immunosuppressive cells will performed, correlating them to clinical outcome in a cohort of stage III disease, treated by radiochemotherapy and immunotherapy as maintenance, and stage IV treated by immunotherapy as first-line treatment. Furthermore, we will analyse cellular mechanisms by in vitro studies, assessing the effect of immunosuppressive cells, provided by fresh tumor samples, on phenotype and functions of lung cancer cell lines. The aim of this study is to better characterize immunosuppressive landscape of NSCLC and mechanisms involved in their protumor functions.
The purpose of this study is the identification of the intersegmental plane and navigation during sublobar pulmonary resections in lung cancer using Hyperspectral Imaging, the comparison with ICG fluorescence intersegmental plane identification, and the establishment of automatic intersegmental plane navigation using machine learning strategies for intraoperative navigation.
In image-guided radiotherapy (IGRT), the repeated and increasingly intensive use of on-board positioning imaging, using 2D or 3D Mega-Volt (MV) or kilo-Volt (kV) imaging devices (cone-beam or CBCT scanners), is leading the international medical community to question the potential impact of these additional doses delivered to the patient, especially in at-risk populations such as children and young adults. The doses delivered to the patient by positioning imaging are still relatively unknown, due to the lack of experimental means and software available in clinical routine to easily and accurately evaluate these doses. The main objective is to estimate by personalized Monte Carlo calculation the physical doses delivered to the patient's organs by the onboard imaging systems during their radiotherapy treatment. The obtained imaging doses will be compared according to different irradiation scenarios commonly used in clinical routine as well as according to the treated location.
Lung cancer is the second-most commonly diagnosed cancer among U.S. Veterans. Significant advances have been made in screening and treatment of lung cancer. Longevity following lung cancer has increased. After lung cancer treatment however, many Veterans experience losses in functional capacity and increased symptoms. Rehabilitation services are needed to address these health issues. This study will evaluate a telerehabilitation intervention with Veterans after lung cancer treatment, with goals to improve their function and quality of life, and advance knowledge on strategies to better meet the rehabilitation needs of Veteran lung cancer survivors following treatment. It will also develop the career of a physician researcher to acquire expertise in rehabilitation services for many Veteran lung cancer survivors.
Investigations prospectively collected the SCLC patients who received current standard first-line treatment, the response was not progression disease(PD). and then participants receive Anlotinib 12mg, administered as PO on Day1-14 of each 21-day cycle until documented PD or had unacceptable toxicity. This regimen is compared to the effects a observation without treatment after the first-line therapy. The aim of the study is therefore to evaluate the efficacy and safety of Anlotinib as maintenance treatment after first-line chemotherapy in SCLC patients.
