Adaptive Stereotactic-body Radiation Therapy (SBRT) Planning for Lung Cancer Significance and Innovation: Tumor shrinkage during SBRT of lung cancer
ثبت نشده
چکیده
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. This is especially important for tumors adjacent to OARs, such as centrally located tumors. It is the objective of this study to evaluate potential dosimetric advantages of adaptive SBRT over non-adaptive SBRT for selected lung cancer patients.

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 ...

Background: Radiation Pneumonia (RP) is one of the most extensive side effects in Stereotactic Body Radiotherapy (SBRT) of lung cancer. SBRT are performed by means of Intensity Modulated Radiotherapy (IMRT), Intensity Modulated Arc Therapy (IMAT), CyberKnife (CK) or Helical Tomotherapy (HT) treatment methods. In this study, we performed a plan study to determine the plan parameter such as the M...

Stereotactic body radiation therapy (SBRT) is a newly developed technique currently in clinical use. SBRT originated from stereotactic radiosurgery for intracranial tumors. SBRT has been widely used clinically for lung cancer. The practice of SBRT demands different kinds of patient fixation, breathing control, target determination, treatment planning, and verifications. The history and current ...

Stereotactic body radiation therapy (SBRT) plays an important role in early stage non-small cell lung cancer. Tumor growth before radiotherapy planning (RTP) or during SBRT has been reported in lung cancer patients; however, little is known of growth during the period in-between (i.e. after RTP but before SBRT). An 83-year-old man referred to our hospital and diagnosed with medically inoperable...
