These are presented and discussed in this contribution. A recently finished ph.d.-study has evaluated the symbolic safety culture approach and found four advantages and two disadvantages. Safety culture is a major issue in accident research. With so many definitions and phases of distance education, this paper only focuses on the delivery mode of distance education (the use of information technology), background, and its disadvantages and advantages for today’s learners.Īdvantages and disadvantages by using safety culture The use of the method of polyfocal transperineal biopsy during the brachytherapy session provides information on the volumetric spread of prostate cancer and adjust the dosimetry plan taking into account the obtained data.ĭistance learning: its advantages and disadvantagesĭistance learning has become popular in higher institutions because of its flexibility and availability to learners and teachers at anytime, regardless of geographic location. These studies of the advantages of high dose brachytherapy lead to the conclusion that this method of radiation treatment for prostate cancer has a favorable advantage in comparison with remote sensing methods, and is competitive, preserving organs in comparison to surgical methods of treatment. This article analyzes the results of prostate brachytherapy. One of the modern methods of preserving organs radiation treatment is brachytherapy. International Nuclear Information System (INIS)īensaleh, Saleh Bezak, Eva Borg, MartinĪdvantages of high-dose rate (HDR) brachytherapy in treatment of prostate cancer Initial clinical results have shown that the MammoSite device could be used as a sole radiation treatment for selected patients with early stage breast cancer Some BTPS predicted up to 10% higher dose near the balloon surface compared with Monte Carlo calculations using various contrast concentrations (5-25%). Current brachytherapy treatment planning systems (BTPS) do not take into account the increased photon attenuation due to high Z of contrast. ![]() The contrast medium inside the balloon causes dose reduction at the prescription point. The available data on the local control achieved with the MSB were comparable with other accelerated partial breast irradiation techniques. There have been very few published data regarding the long term tumour control and cosmesis associated with the MSB. Good-to-excellent cosmetic results are achieved for patients with balloon-skin spacing of =7 mm. The optimal cosmetic results depend on the balloon-to-skin distance. Potential advantages of MSB are: high localised dose with rapid falloff for normal tissue sparing, minimum delay between surgery and RT, catheter moves with breast, improved local control, no exposure to staff, likely side-effects reduction and potential cost/time saving (e.g. This review article presents the advantages, disadvantages, uncertainties and clinical outcomes associated with the MammoSite brachytherapy (MSB). The treatment schedule for the MammoSite monotherapy is 34 Gy delivered in 10 fractions at 1.0 cm from the balloon surface with a minimum of 6 hours between fractions on the same day. The device is placed inside the breast surgical cavity and inflated with a combination of saline and radiographic contrast to completely fill the cavity. The MammoSite radiotherapy system is an alternative treatment option for patients with early-stage breast cancer to overcome the longer schedules associated with external beam radiation therapy. of Radiation Oncology, Royal Adelaide Hospital, Adelaide (Australia))īackground. ![]() Review of MammoSite brachytherapy: Advantages, disadvantages and clinical outcomesĮnergy Technology Data Exchange (ETDEWEB)īensaleh, Saleh Bezak, Eva Borg, Martin (Dept.
