Objective: Intraoperative electron radiotherapy (IOERT) applied as boost to the tumor bed during breast conserving surgery is advantageous in terms of local recurrence cancer patients. In addition, it has other advantages over adjuvant RT such no risk change, ease sequencing chemotherapy, and reduced workload clinic. This study aimed evaluate long-term results our patients who were treated with...
One of the most relevant risks in breast intraoperative electron radiotherapy (IOERT) is the incorrect positioning of the shielding disc. If such a setup error occurs, the treatment zone could receive a nonuniform dose delivery, and a considerable part of the electron beam could hit - and irradiate - the patient's healthy tissue. However misalignment and tilt angle of the shielding disc can be ...
The term IORT (intraoperative radiotherapy) is currently used for various techniques that show huge differences in dose delivery and coverage of the tissue at risk. The largest evidence for boost IORT preceding whole breast irradiation (WBI) originates from intraoperative electron treatments (IOERT) with single doses around 10 Gy. At median follow-up periods at 6 years, outstandingly low local ...
Intraoperative electron radiation therapy (IOERT) cannot usually benefit, as conventional external radiotherapy, from software systems of treatment planning based on computed tomography and from common dose verify procedures. For this reason, in vivo film dosimetry (IVFD) proves to be an effective methodology to evaluate the actual radiation dose delivered to the target. A practical method for ...
For resected and unresectable pancreas cancers, data will be summarized from both adjuvant and locally unresectable pancreas cancer series (EBRT +/- IOERT) to demonstrate the justification of continuing to utilize chemo-irradiation as a component of treatment. The resultant improvements in local control with combined modality treatment, however, achieve only minimal improvements in survival in ...
