Filter by:The study aims to develop an improved method to tailor the geometric safety margin when treating with stereotactic body radiotherapy (SBRT), to avoid tumour cells being missed during irradiation and to limit the exposure of normal tissues as much as possible. Dynamic magnetic resonance imaging (MRI) is assumed to represent the tumour motion during the respiratory cycle more realistically, compared to 4-dimensional computed tomography (4D CT), thanks to its high temporal resolution and the possibility to image the motion over a longer period of time. Patients receiving SBRT for a pulmonary target located below the level of the carina are included in the study, and the hypothesis will be tested through a comparison of the tumour amplitude measured with each modality. Furthermore, the predictive value of the image series acquired at treatment planning, for the motion patterns observed at each treatment fraction, will be evaluated through repeated 4D CBCT acquisitions.
This is a phase 0, pilot prospective study to determine the feasibility of combined irreversible electroporation (IRE) and radiation therapy in subjects with lung tumors with metastatic cancer of any histology. These are subjects who have advanced disease (stage IV) or previously treated disease that has become progressive, recurrent, or metastatic.
This study concluded that lung rehabilitation exercise programs can improve the psychological distress, self-efficacy, quality of life, six-minute walk distance, muscle strength, and reduce the number of hospitalizations for patients with advanced lung cancer.
The purpose of this study is to further evaluate the efficacy and safety of niraparib in patients with locally advanced or metastatic solid tumors and a pathogenic or likely pathogenic tumor PALB2 (tPALB2) mutation.
It is well known that video-assisted thoracoscopic surgery (VATS) is preferred to open surgery for lung resection because of the smaller incisions and optimized postoperative recovery, including a shorter length of hospitalization and much decreased local tenderness. Studies have shown less operative and post-operative morbidity with decreased operative times. However, for small nodules (i.e. lesions <1 cm or those at a distance more than 1.5cm from the lung periphery), adequate identiļ¬cation of the target nodule has been being difficult by VATS with necessity of more significant resection or thoracotomy conversion to ensure complete tumor resection. In order to improve nodule localization, a variety of preoperative localization methods such as CT-guide hook wire or methyl blue dye localization have been proposed. It has been proved to be much easier to mark lung nodules and help guide resection during VATS. However, there are certain concerns. First, it is difficult to minimize the time between the localization procedure and the subsequent surgery in reality. Second, there is concern for patient safety, in particular pneumothorax or hemothorax, during transferred to and from the ward to the radiology suit and in the frequent delays and waiting in reception areas prior to transfer to operating theaters. Finally, interdepartmental transfers and delays can also increase the risk of hook wire dislodgement. Theoretically, the aforementioned disadvantage could be solved by performing the localization procedure and the lung surgery in the same operating room environment. We performed single-step localization and removal of small pulmonary nodules in the hybrid OR equipped with floor-mounted C-arm cone-beam computed tomography (CBCT) in the previous study. However, it costed a lot of money and every localization could only be performed in the hybrid OR. Mobile 3D C-arm CT is another form of CBCT. It depicts soft tissues with high contrast but also offer a more affordable solution with relative low cost. In this case series, we will investigate the use of a mobile 3D C-arm CT for single-step localization and removal of small pulmonary nodules.
The proposed study expands on the principles of SBRT (Stereotactic Body Radiation Therapy) and SABR (Stereotactic Ablative Radiotherapy) for centrally located NSCLC (Non-Small Cell Lung Cancer) to further optimize outcomes in this patient population with utilization of the adaptive workflow to maintain tumor control rates but decrease the incidence and grade of treatment-related toxicities.
The Multi-OutcoMe EvaluatioN of radiation Therapy Using the Unity MR-Linac Study (MOMENTUM) is a multi-institutional, international registry facilitating evidenced based implementation of the Unity MR-Linac technology and further technical development of the MR-Linac system with the ultimate purpose to improve patients' survival, local, and regional tumor control and quality of life.
Whether using a guide sheath can increase the diagnostic yield rate after the lesion is located by radial endobronchial ultrasound
This is a pilot study for placement of a tiny microdevice into lung tumors to more precisely predict tumor-specific drug sensitivity, and to help inform systemic therapeutic decisions. The microdevice will provide a novel technique for interrogating human lung tumor tissue in situ, and will uniquely facilitate assessment of response to multiple drugs simultaneously. This will not only increase the specificity of a particular participant's chosen systemic therapy, it will also augment the speed and efficiency with which investigators are able to make clinical decisions regarding choice of therapy.
