Dosimetric characteristics of a new unit for electronic skin brachytherapy
PURPOSE Brachytherapy with radioactive high dose rate (HDR) (192)Ir source is applied to small skin cancer lesions, using surface applicators, i.e. Leipzig or Valencia type. New developments in the field of radiotherapy for skin cancer include electronic brachytherapy. This technique involves the placement of an HDR X-ray source close to the skin, therefore combining the benefits of brachythera...
متن کاملDetermination of Dosimetric Characteristics of IrSeed 125I Brachytherapy Source
Introduction Low dose rate brachytherapy sources have been widely used for interstitial implants in tumor sites, particularly in prostate. Dosimetric characteristics of a new IrSeed 125I brachytherapy source have been determined using the LiF thermoluminescent dosimeter (TLD) chips. Materials and Methods Dose rate constant, radial dose function, and anisotropy function around the IrSeed 125I so...
متن کاملClinical implementation of a new electronic brachytherapy system for skin brachytherapy
Although surgery is usually the first-line treatment for nonmelanoma skin cancers, radiotherapy (RT) may be indicated in selected cases. Radiation therapy as primary therapy can result in excellent control rates, cosmetics, and quality of life. Brachytherapy is a radiation treatment modality that offers the most conformal option to patients. A new modality for skin brachytherapy is electronic b...
متن کاملComments on: "Clinical implementation of a new electronic brachytherapy system for skin brachytherapy".
We have read with an interest the article of Olga Pons-Llanas et al. [1] published in the Journal about the use of electronic brachytherapy (EBT) in non-melanoma skin cancer (NMSC). However, we noticed the exclusion criteria for the following tumors: lesions with a diameter greater than 20 mm, invasion of more than 4 mm, irregular anatomic areas. Besides, there are limits linked to the use of c...
