Digital Mammography for the Detection and Preoperative Staging of Breast Cancer

2014-08-27 03:15:16 | BioPortfolio

Summary

Breast tumors are normally seen with mammography or ultrasound without the use of a dye but the size and extent of the tumor may be hard to see. Currently, after initial mammography, many patients undergo bilateral breast MR to further stage the local tumor. It is able to not only detect anatomic abnormalities but can also evaluate changes such as the development of new blood vessels, which occurs with the development of cancers. MRI is extremely sensitive and detects unsuspected disease in up to 25% of patients, which affects their treatment. It also detects unsuspected cancer in the other breast in some patients.

However, MRI is expensive, not always available, and some patients are unable to undergo MRI due to the presence of pacemakers, clips, or claustrophobia. Dual Energy Contrast Enhanced Digital Mammography (DE CEDM) is an investigational procedure that uses a non-standard contrast in a regular digital mammography exam that has been changed to give the needed dual energy and image. DE CEDM is not FDA approved. It is our hope that DE CEDM will also be able to detect unknown tumors because it will also detect new blood vessels. It is less expensive than MRI, could be more available to patients, and can be done on patients with pacemakers and clips. Claustrophobia will not be a problem. We plan to see if (DE CEDM) will help us better see the breast tumor and size of the breast tumor. We will also want to see if DE CEDM can detect additional unsuspected disease in the breast with the known tumor and in the other breast without a known tumor.

Medical and Biotech [MESH] Definitions

Measurement of relative composition of different BREAST tissue types often determined from MAMMOGRAPHY; ULTRASONOGRAPHY; or MRI.

Radiographic examination of the breast.

Substances used to allow enhanced visualization of tissues.

A method of producing a high-quality scan by digitizing and subtracting the images produced by high- and low-energy x-rays.

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)
