Stereotactic Radiotherapy for Liver Metastases
Liver metastases are common in oncologic patients, causing substantial morbidity and mortality. Systemic therapy is now standard palliative treatment for most patients with liver metastases, often providing transient responses and increased overall survival. In selected oligometastatic patients, local treatment can lead to long disease-free intervals and even permanent disease control. Although...
متن کاملStereotactic body radiotherapy for liver metastases.
The role for local ablative therapies in the management paradigm of oligometastatic liver disease is increasing. The evidence base supporting the use of stereotactic body radiotherapy for liver metastases has expanded rapidly over the past decade, showing high rates of local control with low associated toxicity. This review summarises the evidence base to date, discussing optimal patient select...
متن کاملStaging of liver metastases with MRI in oncological treatment planning
Metastastic disease in the liver is a very common clinical situation in oncology. The liver is one of the most common sites of metastatic spread of epithelial cancers, second only to regional lymph nodes. The true prevalence of metastatic disease is unknown, but approximately 20%-25% of patients with colorectal cancer have liver metastases at the time of diagnosis. Studies based on autopsy resu...
متن کاملStereotactic body radiation therapy for liver metastases and primary hepatocellular carcinoma: normal tissue tolerances and toxicity.
BACKGROUND There is growing interest in stereotactic body radiation therapy (SBRT) as a noninvasive means of treating inoperable hepatic metastases and primary intrahepatic hepatobiliary carcinomas. While initial outcomes are encouraging, the safety of delivering such large, ablative doses is still being studied. METHODS We compiled all dose-volume constraints from seven prospective trials of...
متن کاملVolumetric modulated arc therapy treatment planning of thoracic vertebral metastases using stereotactic body radiotherapy
PURPOSE/OBJECTIVES To retrospectively evaluate the plan quality, treatment efficiency, and accuracy of volumetric modulated arc therapy (VMAT) plans for thoracic spine metastases using stereotactic body radiotherapy (SBRT). MATERIALS/METHODS Seven patients with thoracic vertebral metastases treated with noncoplanar hybrid arcs (NCHA) (1 to 2 3D-conformal partial arcs +7 to 9 IMRT beams) were ...
