Adaptive Stereotactic-body Radiation Therapy (SBRT) Planning for Lung Cancer Significance and Innovation: Tumor shrinkage during SBRT of lung cancer
Introduction: SBRT is an emerging radiotherapy technique for treating early-stage non-small cell lung cancers (NSCLC) or oligometastatic lesions to the lung [3, 4]. Significant tumor shrinkage has been observed in some patients during the course of SBRT [1, 2]. Adaptive planning has the potential to reduce radiation dose to organs of risk (OARs), and further escalate radiation dose to the tumor...
متن کاملThe colossal circumvention of the lung lesion during lung stereotaxy
This is a case report on stereotaxic (Stereotactic Body Radiotherapy-SBRT) for lung cancer located in the left lower lobe (Segment 6, S6). There have been no reports on marked displacement of the peripheral lung cancer during radiotherapy. A pulmonary nodule was discovered on computed tomography (CT) conducted for a persistent cough in an 87-year-old male. According to diagnostic imaging, this ...
متن کاملStereotactic Body Radiotherapy for Small Lung Tumors in the University of Tokyo Hospital
Our work on stereotactic body radiation therapy (SBRT) for primary and metastatic lung tumors will be described. The eligibility criteria for SBRT, our previous SBRT method, the definition of target volume, heterogeneity correction, the position adjustment using four-dimensional cone-beam computed tomography (4D CBCT) immediately before SBRT, volumetric modulated arc therapy (VMAT) method for S...
متن کاملSalvage SBRT for Previously Irradiated Lung Cancer
Purpose: Patients with locally recurrent lung cancer after definitive radiation therapy pose a challenge in management. Surgery is often not an option and chemotherapy offers poor long-term local control. Stereotactic body radiotherapy (SBRT) was investigated in an attempt to salvage locally recurrent lung cancer. Materials and Methods: From March, 2009 to January, 2010, 8 patients who had prev...
متن کاملAccuracy and inter-observer variability of 3D versus 4D cone-beam CT based image-guidance in SBRT for lung tumors
BACKGROUND To analyze the accuracy and inter-observer variability of image-guidance (IG) using 3D or 4D cone-beam CT (CBCT) technology in stereotactic body radiotherapy (SBRT) for lung tumors. MATERIALS AND METHODS Twenty-one consecutive patients treated with image-guided SBRT for primary and secondary lung tumors were basis for this study. A respiration correlated 4D-CT and planning contours...
