Background: New techniques of radiation therapy are being introduced in the management of breast cancer. One of the most rapidly emerging new techniques is intensity modulated radiotherapy (IMRT). Aim of the Study: The purpose of the study is to compare between two different techniques of radiation therapy of breast cancer for intact breasts after breast conservative therapy (BCT); IMRT and dyn...

BACKGROUND Relative to Western women, Korean women show several differences in breast-related characteristics, including higher rates of dense breasts and small breasts. We investigated how mammographic composition and breast size affect the glandular dose during full-field digital mammography (FFDM) in Korean women using a radiation dose management system. METHODS From June 1 to June 30, 201...

We present three cases of patients with breast cancer and psoriasis who received radiotherapy following breast-conserving surgery. One patient developed an extensive flare-up during chemotherapy. After discontinuing chemotherapy, she conventional to the ipsilateral whole breast, axillary, supraclavicular lymph nodes 50.4 Gy in 28 fractions boosted 10 five tumor bed. Two hypofractionated whole-b...

background: tangential irradiation of intact breast is one of the most common procedures performed in any radiotherapy center. this method is performed by using 2d and 3d treatment planning. the aim of this study was to compare 2d with 3d plans in breast conserving radiotherapy. homogeneity of isodose, and lung received dose were compared. materials and methods: twenty patients with breast canc...

The comparison of the pencil beam dose calculation algorithm with modified Batho heterogeneity correction (PBC-MB) and the analytical anisotropic algorithm (AAA) and the mutual comparison of advanced dose calculation algorithms used in breast radiotherapy have focused on the differences between the physical dose distributions. Studies on the radiobiological impact of the algorithm (both on the ...

The current study aimed to: a) utilize Monte Carlo simulation methods for the assessment of radiation doses imparted to all organs at risk to develop secondary radiation induced cancer, for patients undergoing radiotherapy for breast cancer; and b) evaluate the effect of breast size on dose to organs outside the irradiation field. A simulated linear accelerator model was generated. The in-field...

Conformal Radiation Therapy (3DCRT) and Intensity Modulated Radiotherapy (IMRT) improve the relationship between tumor control and complications in normal tissue. However, these techniques may cause an increase of the normal tissue volume irradiated with low doses or an increase of the doses outside the beam. The aim of this work was to measure and compare the scatter dose to the contralateral ...

OBJECTIVE To assess the breast dose during a routine thoracic cone-beam CT (CBCT) check with the efforts to explore the possible dose reduction strategy. MATERIALS AND METHODS Metal oxide semiconductor field-effect transistor (MOSFET) dosimeters were used to measure breast surface doses during a thorax kV CBCT scan in an anthropomorphic phantom. Breast doses for different scanning protocols a...
