Advances in radiation therapy for brain tumors.
Radiation therapy is used postoperatively as adjunctive therapy to decrease local failure; to delay tumor progression and prolong survival; as a curative treatment; as a therapy that halts further tumor growth; to alter function; and for palliation. Registration of MRI scan data sets with the treatment-planning CT scan is essential for accurate definition of the tumor and surrounding organs at ...
متن کاملTechnological Progress in Radiation Therapy for Brain Tumors
To achieve a good therapeutic ratio the radiation dose to the tumor should be as high as possible with the lowest possible dose to the surrounding normal tissue. This is especially the case for brain tumors. Technological advancements in diagnostic imaging, dose calculations, and radiation delivery systems, combined with a better understanding of the pathophysiology of brain tumors have led to ...
متن کاملRadiation therapy for older patients with brain tumors
The incidence of brain tumors in the elderly population has increased over the last few decades. Current treatment includes surgery, radiotherapy and chemotherapy, but the optimal management of older patients with brain tumors remains a matter of debate, since aggressive radiation treatments in this population may be associated with high risks of neurological toxicity and deterioration of quali...
متن کاملReducing excess radiation from portal imaging of pediatric brain tumors
Previously we have shown that our routine portal imaging (PI) of the craniofacial region in pediatric brain tumor patients contributed an additional 2%-3% of the prescribed dose and up to 200 cGy to the planning target volume (PTV) and nearby organs at risk (OARs). The purpose of this study is to quantify the reduction in dose to PTV and OARs from portal imaging (PI) of the craniofacial region ...
متن کاملImmunotherapy for Pediatric Brain Tumors
Malignant brain tumors are the most common cause of solid cancer death in children. New targeted therapies are vital to improve treatment outcomes, but must be developed to enable trafficking across the blood brain barrier (BBB). Since activated T cells cross the BBB, cancer immunotherapy can be harnessed to unlock the cytotoxic potential of the immune system. However, standard of care treatmen...
