Background/aim: To compare implant sparing irradiation with conventional radiotherapy (RT) using helical (H) and TomoDirect (TD) techniques in breast cancer patients undergoing immediate breast reconstruction (IBR).
Patients And Methods: The dosimetric parameters of 40 patients with retropectoral implants receiving 50.4 Gy delivered in 28 fractions were analyzed.
Article Synopsis
- The study assessed the impact of reducing the planning target volume (PTV) margin in MR-guided radiotherapy (MRgRT) on radiation dose distribution for low-risk prostate cancer patients.
- Both MR-Linac (MRL) plans with reduced and normal margins were compared against a conventional IMRT plan, revealing that all plans met coverage and dose constraints.
- Results indicated that while MRL plans delivered higher doses to the target, the reduced margin plan significantly minimized radiation exposure to surrounding organs like the rectum and bladder compared to the conventional IMRT.

Background: The aim of the study was to perform dosimetric comparisons of helical (H) and TomoDirect (TD) plans for whole-breast irradiation (WBI) with simultaneous integrated boost (SIB) in early-stage breast cancer patients undergoing breast conserving surgery.
Materials And Methods: Fifty patients, 25 with left-side and 25 with right-side tumors, were determined for a treatment planning system for a total dose of 50.4Gy in 1.
We aimed to evaluate contralateral breast doses calculated with a Treatment Planning System (TPS) and verified with metal oxide semiconductor field effect transistor (MOSFET) detectors in patients with early-stage breast cancer (BC) who received helical tomotherapy (HT) after breast-conserving surgery. The dosimetric data of 30 patients (15 left-sided and 15 right-sided) with BC treated with 50.4 Gy to the whole breast and 64.

Materials And Methods: Testicular doses in 40 intermediate- and high-risk prostate cancer patients were determined on treatment planning system (TPS) using the VMAT technique at 6 MV. Scattered testicular doses were also measured by MOSFET detectors placed on testis surface.
