Imaging procedures utilised for patient position verification during breast radiotherapy can add a considerable dose to organs surrounding the target volume on top of therapeutic scatter dose. This study investigated the dose from a breast kilovoltage cone-beam CT (kV-CBCT), a breast megavoltage fan-beam CT (MV-FBCT), and a TomoDirect breast treatment. Thermoluminescent dosimeters placed within...
Silicone lymphadenopathy is a recognized complication of silicone gel implant rupture; the ipsilateral axillary lymph nodes are most commonly involved. We report imaging findings on a range of different imaging modalities and biopsy results in a case of biopsy-proven silicone lymphadenitis involving contralateral intramammary and axillary lymph nodes in a patient with an intact standard dual-lu...
BACKGROUND Risk of invasive cancer following treatment for ductal carcinoma in situ (DCIS) is associated with both treatment- and tumor-related factors. However, it is unknown whether stromal factors such as breast density may also influence subsequent invasive breast events. We investigated whether breast density is an independent predictor of subsequent breast events among women treated for D...
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...
Objective: The main objective of this study was to analyze the differences in ipsilateral and contralateral internal mammary artery (IMA) and lateral thoracic artery (LTA) width in patients with malignant and benign breast tumor. Materials and Methods: A total of 104 female patients, of which 41 had benign and 63 had malignant tumors, were included in the study. The diameters of the IMA and LTA...
BACKGROUND Contralateral second primary breast cancers occur in 4% of female breast cancer survivors. Little is known about differences in risk for second primary breast cancers related to the estrogen and progesterone receptor (hormone receptor [HR]) status of the first tumor. METHODS We calculated standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) for contralateral prim...
BACKGROUND Reliable estimates of cancer risk are critical for guiding management of BRCA1 and BRCA2 mutation carriers. The aims of this study were to derive penetrance estimates for breast cancer, ovarian cancer, and contralateral breast cancer in a prospective series of mutation carriers and to assess how these risks are modified by common breast cancer susceptibility alleles. METHODS Prospe...
BACKGROUND Fenretinide, a vitamin A analogue, has been shown to inhibit breast carcinogenesis in preclinical studies. We determined the efficacy of fenretinide in preventing a second breast malignancy in women with breast cancer. METHODS We randomly assigned 2972 women, aged 30-70 years, with surgically removed stage I breast cancer or ductal carcinoma in situ to receive for 5 years either fe...
The use of contralateral risk reducing mastectomy (CRRM) is indicated in women affected by breast cancer, who are at high risk of developing a contralateral breast cancer, particularly women with genetic mutation of BRCA1, BRCA2 and P53. However we should consider that the genes described above account for only 20-30% of the excess familiar risk. What is contralaterally indicated when genetic a...
