introduction: breast conserving radiotherapy is one of the most common procedures performed in any radiation oncology department. a tangential parallel-opposed pair is usually used for this purpose. this technique is performed using 2d or 3d treatment planning systems. the aim of this study was to compare 2d treatment planning with 3d treatment planning in tangential irradiation in breast conse...

background: to compare the cosmetic results of whole breast radiotherapy between cobalt 60 and photon 9megavolt in patients underwent breast conserving surgery. methods: the patients with breast saving surgery who were treated by whole breast radiotherapy with either cobalt 60 or photon 9mv between 2001-2006 in sayed-al-shohada hospital entered the study. the cosmetic results were evaluated by ...

PURPOSE To compare organ specific cancer incidence risks for standard and complex external beam radiotherapy (including cone beam CT verification) following breast conservation surgery for early breast cancer. METHOD Doses from breast radiotherapy and kilovoltage cone beam CT (CBCT) exposures were obtained from thermoluminescent dosimeter measurements in an anthropomorphic phantom in which th...

BACKGROUND Large breast size is associated with increased risk of late adverse effects after surgery and radiotherapy for early breast cancer. It is hypothesised that effects of radiotherapy on adipose tissue are responsible for some of the effects seen. In this study, the association of breast composition with late effects was investigated along with other breast features such as fibroglandula...

Introduction: Breast cancer is one of the most common known cancers in women all around the world. It is the most common cause of death in women after lung cancer. Radiotherapy is a method for therapy of cancer in which certain dose of high energy radiations is used to destruct cancer cells. Radiotherapy is designed so that radiation of eartain does to the target area in body i...

introduction: delivering maximum dose to tumor and minimum dose to normal tissues is the most important goal in radiotherapy. according to icru, the maximum acceptable uncertainty in the delivered dose compared to the prescribed dose should be lower than 5%, and this is because of the relationship between absorbed dose, tumor control and normal tissue damage. absorbed dose accuracy is investiga...

results no correlation between as and history of rt, rt-to-follow-up time interval, laterality of bc, framingham’s 10-year risk score or traditional cad risk factors were detected. increase in cacs related to the senile atherosclerotic process was shown (p < 0.001). conclusions no difference between cacs was noted between bc patients with a history of 3d-crt and the non-bc women without a histo...

BACKGROUND Breast cancer is the most common type of cancer among women, and the second cause of cancer mortality after pulmonary cancer in this gender. Radiotherapy is one of the major treatments, which locally controls the disease and prohibits in recurrency. Radiation pneumonitis is one of the radiotherapy complications, which usually occurs within 1.5-3 months after radiotherapy. As there is...

PURPOSE The objective of this study was to investigate the influence of radiotherapy on the cosmetic outcome after immediate breast reconstruction using an absorbable mesh in breast cancer. METHODS From July 2008 to July 2009, 35 breast cancer patients who received immediate breast reconstruction with absorbable mesh insertion at the time of breast conserving surgery followed by radiotherapy ...

BACKGROUND There is a paucity of data regarding outcomes for patients undergoing breast augmentation with implants after breast conservation surgery (BCS) and radiotherapy. This retrospective study examined outcomes for patients with breast implant-only augmentation after BCS and radiotherapy. METHODS Between June 1998 and December 2010, 671 women underwent prosthetic breast reconstruction. N...
