SuPr Study (Supine Versus Prone Treatment Position in Breast Radiotherapy)
A randomised, two-arm, non-blinded crossover study investigating the impact of treatment position (prone versus supine) upon reproducibility of tumour bed position in patients undergoing breast radiotherapy following excision of early breast cancer.
To establish whether or not the prone (face down) position reduces exposure of healthy tissue to radiation when compared to the supine position. To compare patient comfort and acceptability in each of the prone and supine positions. To perform a time and motion study for radiotherapy planned and delivered in each of the prone and supine positions.
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Open Label

Inflammatory Breast Neoplasms
Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
Use of ultrasound for imaging the breast. The most frequent application is the diagnosis of neoplasms of the female breast.
A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
Elasticity Imaging Techniques
Non-invasive imaging methods based on the mechanical response of an object to a vibrational or impulsive force. It is used for determining the viscoelastic properties of tissue, and thereby differentiating soft from hard inclusions in tissue such as microcalcifications, and some cancer lesions. Most techniques use ultrasound to create the images - eliciting the response with an ultrasonic radiation force and/or recording displacements of the tissue by Doppler ultrasonography.
Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
The investigators hope to prove that radiation and surgical scarring does not result in changes that affect the MBI pattern 6-12 months after completion of treatment.

RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells. It is not yet known whether a single dose of radiation therapy is more effective than...
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Placing gold markers in the area where the tumor was removed may help doctors better direct radiation therapy and...
To determine if functional MRI methods will aid planning of a radiation dose boost within the prostate in patients with prostate cancer potentially improving safety and efficacy.
INTRODUCTION: Radiation from medical imaging may induce cellular damage and increase the risk of cancer. While health care workers are restricted to an annual dose of 50 milliSieverts (mSv), the expos...
Accelerated partial breast irradiation (APBI) is an alternative to receiving whole breast radiation in carefully selected patients. Because breast cancer local recurrence rates are low and follow-...
Purpose: To compare radiation doses and lifetime attributable risks (LARs) of radiation-induced cancer incidence and mortality from breast imaging studies involving the use of ionizing radiation. Mate...
OBJECTIVE: Ionizing radiation, an established breast cancer risk factor, has been shown to induce oxidative damage and chronic inflammation. Polymorphic variation in oxidative stress and inflammatory-...
