Radiotherapy to the whole brain is standard treatment for cancer that has spread to the brain (brain metastases) as it treats both the metastases that can be seen on scans and the brain me...
Brain metastases are the most common intracranial tumors in adults. Whole-brain radiation therapy (WBI) increases the median survival of patients with brain metastases up to 3-6 months, bu...
Spinal metastases indicate for an incurable course of disease. Local tumor control after palliative radiotherapy of spinal metastases (10x3 Gy, 1x8Gy) is between 61 to 81%. In 30% of patie...
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Giving radiation therapy after surgery to remove brain metastases may decrease the amount of radiation required ...
The goal of this clinical research study is to compare changes to the tumor(s) in participant's breast before and after radiation. Radiation treatment is standard treatment after surgery ...
Radiation therapy (RT) is an effective treatment for primary brain tumors and intracranial metastases, but can occasionally precede new enhancing lesions on imaging studies that are difficult to disce...
This study evaluates the safety and efficacy of moderately hypofractionated radiation therapy (RT) with simultaneous integrated boost (HSIB) intensity modulated RT (IMRT) that includes coverage of the...
Historically, whole brain radiation therapy (WBRT) has been the main treatment for brain metastases. Stereotactic radiosurgery (SRS) delivers high-dose focused radiation and is being increasingly util...
There is increasing evidence that cerebral microangiopathy reduces number of brain metastases. Aim of this study was to analyse if vascular risk factors (arterial hypertension, diabetes mellitus, smok...
We evaluated the efficacy and safety of risk-adapted, proton-based stereotactic body radiation therapy (SBRT) for liver metastases from solid tumors.
Irradiation of one half or both halves of the body in the treatment of disseminated cancer or widespread metastases. It is used to treat diffuse metastases in one session as opposed to multiple fields over an extended period. The more frequent treatment modalities are upper hemibody irradiation (UHBI) or lower hemibody irradiation (LHBI). Less common is mid-body irradiation (MBI). In the treatment of both halves of the body sequentially, hemibody irradiation permits radiotherapy of the whole body with larger doses of radiation than could be accomplished with WHOLE-BODY IRRADIATION. It is sometimes called "systemic" hemibody irradiation with reference to its use in widespread cancer or metastases. (P. Rubin et al. Cancer, Vol 55, p2210, 1985)
Cavity in each of the cerebral hemispheres derived from the cavity of the embryonic neural tube. They are separated from each other by the SEPTUM PELLUCIDUM, and each communicates with the THIRD VENTRICLE by the foramen of Monro, through which also the choroid plexuses (CHOROID PLEXUS) of the lateral ventricles become continuous with that of the third ventricle.
Bleeding into one or both CEREBRAL HEMISPHERES including the BASAL GANGLIA and the CEREBRAL CORTEX. It is often associated with HYPERTENSION and CRANIOCEREBRAL TRAUMA.
A variant of well-differentiated epidermoid carcinoma that is most common in the oral cavity, but also occurs in the larynx, nasal cavity, esophagus, penis, anorectal region, vulva, vagina, uterine cervix, and skin, especially on the sole of the foot. Most intraoral cases occur in elderly male abusers of smokeless tobacco. The treatment is surgical resection. Radiotherapy is not indicated, as up to 30% treated with radiation become highly aggressive within six months. (Segen, Dictionary of Modern Medicine, 1992)
The ability of some cells or tissues to withstand ionizing radiation without serious injury. Tolerance depends on the species, cell type, and physical and chemical variables, including RADIATION-PROTECTIVE AGENTS and RADIATION-SENSITIZING AGENTS.
