different fractionation in whole brain irradiation for multiple brain metastases
background : this study compared the efficacy of two commonly used fractionation schedules for palliative whole brain irradiation in patients with brain metastases, and assessed the association of the radiotherapy therapy oncology group (rtog) recursive partitioning analysis for brain metastases (rpa) to survival with each schedule. methods : patients with multiple (more than three) brain metas...
متن کاملRe-irradiation for metastatic brain tumors with whole-brain radiotherapy.
OBJECTIVE To determine whether second whole-brain irradiation is beneficial for patients previously treated with whole-brain irradiation. METHODS A retrospective analysis was done for 31 patients with brain metastases who had undergone re-irradiation. Initial whole-brain irradiation was performed with 30 Gy/10 fractions for 87% of these patients. Whole-brain re-irradiation was performed with ...
متن کاملSpatial memory and changes in expression of genes of neurotrophic factors in adult rat brain after fractionated whole brain irradiation
Background: Ionizing radiation causes cognitive impairment in adult brain. However, the effects of various irradiation protocols with fractionated fixed total dose on hippocampal function have not yet been studied. Materials and Methods: Fractionated whole brain irradiation with a total dose of 36 Gy was performed according to the following protocols: 2Gy-18 fractions (2Gy*18), 4Gy-9 fraction (...
متن کاملIs Re-Irradiation of Recurrent Metastatic Brain Tumors an Option? Re-Irradiation for Metastatic Brain Tumors With Whole-Brain Radiotherapy
Background: Relapse after whole-brain radiation therapy (WBRT) for multiple cerebral metastases occurs fairly often and is associated with a poor prognosis. Re-irradiation is an option that many defer because of risks of exceeding brain tolerance and resulting toxicity. Objective: To determine if brain re-irradiation is beneficial. Design: Single-institution retrospective study. Methods: Patien...
متن کاملEvaluation of changes in excision cavity volume during whole breast irradiation using secondary CT image
Background: The aim of this study was to evaluate the reduction in excision cavity volume (ECV) during the whole breast radiotherapy (WBRT). The delineating of reduced cavity volume on secondary CT (computed tomography) might decrease the field size of boost plan. Materials and Methods: Twenty patients were treated having breast conservative surgery. At first, primary CT simulation (CT-1) was d...
