Placement of cesium 131 permanent brachytherapy seeds

·The authors submit that utilizing this technique in combination with EEA tumor resection renders a minimally invasive approach to improving local control in a patient with a recurrent anaplastic or atypical meningioma of the skull base Placement of cesium 131 permanent brachytherapy seeds using the endoscopic endonasal approach for

Resection and permanent intracranial brachytherapy using modular

·R BT utilizing Cs 131 sources in modular carriers represents a potentially safe and effective treatment option for recurrent previously irradiated aggressive meningiomas Cesium 131 Cs 131 radiation sources were embedded in modular collagen carriers positioned in the operative bed on completion of resection The Cox proportional hazards

Resection and permanent intracranial brachytherapy

We chose the isotope cesium 131 Cs 131 because of its relatively short half life t 1/2 = days A short t 1/2 is postulated to offer a biological advantage in treating tu mors with relatively short doubling times with 88% of the radiation dose delivered within 30 days versus 200 days for The shorter t 1/2 also markedly lessens

R BT utilizing Cs 131 sources in modular carriers represents a potentially safe and effective treatment option for recurrent previously irradiated aggressive meningiomas OBJECTIVEEffective treatments for recurrent previously irradiated intracranial meningiomas are limited and resection alone is not usually curative Thus the authors studied the combination

Long term outcomes of a prospective randomized trial of

·Iodine 125 125 I is the most commonly used isotope for prostate brachytherapy BT Cesium 131 131 Cs has a higher dose rate and shorter dose delivery time resulting in decreased duration of acute urinary term data suggest excellent oncologic outcomes; it is not known how outcomes compare A prospective randomized trial comparing

Implementation and early clinical results utilizing

1 Cesium 131 Cs 131 is a radioactive isotope with favorable dosimetric properties for interstitial brachytherapy IBT The mean energy of Cs 131 is low and the half life is days leading to a reduced exposure to the patient treating providers and families Coverage and stabilization of the Cs 131 strand was achieved utilizing the

Iodine 125 125I is the most commonly used isotope for prostate brachytherapy BT Cesium 131 131Cs has a higher dose rate and shorter dose delivery time resulting in decreased duration of acute urinary morbidity Long term data suggest excellent oncologic outcomes; it is not known how outcomes compare A prospective randomized trial comparing the two isotopes was initiated

Cesium 131 an overview ScienceDirect Topics

Cesium 131 isotope has a short half life delivers 90% of its dose within a month shortens the time to initiation of systemic therapy compared to iodine 125 or external radiotherapy and has an excellent radiation safety profile Further analyses have demonstrated superior cost effectiveness and quality of life improvement ratios of cesium 131
