Worst case optimization for interfractional motion mitigation in carbon ion therapy of pancreatic cancer
INTRODUCTION The efficacy of radiation therapy treatments for pancreatic cancer is compromised by abdominal motion which limits the spatial accuracy for dose delivery - especially for particles. In this work we investigate the potential of worst case optimization for interfractional offline motion mitigation in carbon ion treatments of pancreatic cancer. METHODS We implement a worst case opti...
متن کاملPalliative radiation therapy for advanced gastrointestinal cancer.
Patients with locally advanced disease can have significant local symptoms. The most common symptoms from local extension are pain, bleeding (hematemesis, melena) and obstruction (dysphagia, vomiting). These can cause a significant impact on a patient's quality of life. Radiation therapy is used to control these symptoms with modern 3-dimensional conformal techniques or brachytherapy. The aim o...
متن کاملCorrelation between patients’ anatomical characteristics and interfractional internal prostate motion during intensity modulated radiation therapy for prostate cancer
Intensity modulated radiation therapy (IMRT) is one of a standard treatment for localized prostate cancer. Although lower complication is expected for smaller target margin, determination of optimal margin is important. For bony-structure based registration, internal prostate motion is the main factor determining the margin from clinical target volume to planning target volume. The purpose of t...
متن کاملQuantification of an External Motion Surrogate for Quality Assurance in Lung Cancer Radiation Therapy
The purpose of this work was to validate the stability of the end exhale position in deep expiration breath hold (DEBH) technique for quality assurance in stereotactic lung tumor radiation therapy. Furthermore, a motion analysis was performed for 20 patients to evaluate breathing periods and baseline drifts based on an external surrogate. This trajectory was detected using stereo infrared (IR) ...
متن کاملIntraoperative radiation therapy (IORT) in pancreatic cancer
Despite the important improvements made in the fields of surgery, chemotherapy and radiation therapy, pancreatic cancer remains one of the most lethal malignancies. Improved outcomes with novel chemotherapy regimes led again to increased attention on the role of localized radiotherapy, since local tumor progression causes significant morbidity and mortality in patients. Even after resection loc...
