The first three-dimensional mammogram device was approved by the U.S. Food and Drug Administration on last Friday, February 11, 2011. The first X-ray mammography device has a three-dimensional image for proper screening and diagnosis for breast cancer.
According to Kristin Byrne, a chief of breast imaging for New York’s Lenox Hill Hospital a three-dimensional mammogram technology can help the women to satisfy the result. And about 10% of their first set of mammograms is not clear enough and require for a follow-up screening, by this first 3D mammogram device approved by FDA it will be lessen the effort of the patient and may help physicians more accurately detect and diagnose breast cancer.
The Selenia Dimensions System, marketed by Hologic Inc. of Bedford, Mass., was approved by the FDA which produces both conventional digital 2-D mammography images and 3-D images, and additionally that 3-D images be taken in tandem with 2-D images.
“Physicians can now access this unique and innovative 3-D technology that could significantly enhance existing diagnosis and treatment approaches,” said Dr. Jeffrey Shuren, director of the FDA’s Center for Devices and Radiological Health.
But according to chairwoman of the American College of Radiology’s committee on breast imaging, Carol Lee said it’s too early to tell how useful the technology will be.
Some studies show that 3-D imaging is better than the 2-D imaging in detecting cancerous growths, and that it helps decrease “false positives” — abnormalities that turn out to be noncancerous. This 3-D mammogram device could reduce the number of needless biopsies.
First 3D mammogram device is considered the best tool for early detection of breast cancer and it has a low-dose X-ray of the breast. Nearly 40 million mammograms are performed each year in the United States. From the U.S. National Cancer Institute, a woman who an age 40 and older recommends has a mammogram every one to two years.
If this new technology becomes widely available, it will help the medical provider to reduce the number of initial mammograms that yields inconclusive results, thus reducing follow-up tests. Hope this new invention a first 3D mammogram device approved by FDA will be lessening the number of deaths from breast cancer.

Health: Terra med Alliance News FDA Approved Leukemia Drugs Shows Promise In Ovarian Cancer Cells
Terra med Alliance News: The drug Sprycel, approved for use by the U.S. Food and Drug Administration in patients with chronic myeloid leukemia, significantly inhibited the growth and invasiveness of ovarian cancer cells and also promoted their death, a study by researchers with UCLA’s Jonsson Comprehensive Cancer Center found.
Terra med Alliance News: The drug, when paired with a chemotherapy regimen, was even more effective in fighting ovarian cancer in cell lines in which signaling of the Src family kinases, associated with the deadly disease, is activated.
The study appears in the Nov. 10, 2009 edition of the British Medical Journal.
Ovarian cancer, which will strike 21,600 women this year and kill 15,500, causes more deaths than any other cancer of the female reproductive system. Few effective therapies for ovarian cancer exist, so it would be advantageous for patients if a new drug could be found that fights the cancer, said Gottfried Konecny, an assistant professor of hematology/oncology, a Jonsson Cancer Center researcher and first author of the study.
“I think Sprycel could be a potential additional drug for treating patients with Src dependent ovarian cancer,” Konecny said. “It is important to remember that this work is only on cancer cell lines, but it is significant enough that it should be used to justify clinical trials to confirm that women with this type of ovarian cancer could benefit.”
Recent gene expression studies have shown that about one-third of women have ovarian cancers with activated Src pathways, so the drug could potentially help 7,000 ovarian cancer patients every year.
In this study, the UCLA team tested the drug against 34 ovarian cancer cell lines and they conducted genetic analysis on all cell lines. Through these analyses, the researchers were able to identify genes that predict response to Sprycel. If the work is confirmed in human studies, it may be possible to test patients for Src activation and select those who would respond prior to treatment, personalizing their care.
“We were able to identify markers in the pre-clinical setting that would allow us to predict response to Sprycel,” Konecny said. “These may help us in future clinical trials in selecting patients for studies of the drug.”
Sprycel is what is known as a “dirty” kinase inhibitor, meaning it inhibits more than one pathway. Konecny said it also inhibits the focal adhesion kinase and ephrin receptor, also associated with ovarian cancer.
The next step, Konecny said, would be to test the drug on women with ovarian cancer in a clinical trial. The tissue of responders would then be analyzed to determine if the Src and other pathways were activated. If that is confirmed, it would further prove that Sprycel could be used to fight ovarian cancer. In studies, women would be screened before entering a trial and only those with Src dependent cancers could be enrolled to provide further evidence, Konecny said, much like the studies of the molecularly targeted breast cancer drug Herceptin enrolled only women who had HER-2 positive disease.
“Herceptin is different because we knew in advance that the only worked in women with HER-2 amplification,” he said. “In this case, we don’t clearly know that yet. The data reassure us that the drug works where the targets are over-expressed but we need more testing to confirm this.”
The tests combining the drug with chemotherapy are significant because chemotherapy currently is the first line treatment for ovarian cancer patients following surgery. Because Sprycel proved to have a synergistic effect when combined with chemotherapy — both made the other work better — it may be possible to add the targeted therapy as a first line treatment if its efficacy is confirmed in future studies, adding a new tool to an oncologist’s arsenal.

Medical therapy for breast cancer can be divided into 3 categories: chemoprevention, neo-adjuvant, and adjuvant therapy. Ductal excision: Ductal excision may be indicated for suggestive nipple discharge without an associated palpable or radiographic lesion. Bloody discharge and spontaneous clear discharge from a single duct are findings with an increased risk of malignancy. Ductal excision can be performed using a small (4.0) lacrimal duct probe to localize the draining duct. A cone-shaped sample of tissue then should be excised around the probe. The most common histologic findings in this setting are intraductal papilloma or ductal ectasia (approximately 80%). Most of the remaining lesions demonstrate intraductal or infiltrating carcinoma.
Excisional biopsy or lumpectomy: This should be performed for palpable lesions with suggestive or malignant findings on needle biopsy. Benign or inconclusive findings on needle biopsy also may prompt excisional biopsy in the presence of high clinical suspicion (eg, large mass fixed to the chest wall, atypical epithelial hyperplasia). In general, circumareolar incisions should be made for lesions close to the nipple and radial incisions for lower outer quadrant lesions. All incisions should be made with consideration of potential need for incorporation into subsequent mastectomy incisions. The surgeon should carefully orient specimens with suture for histologic assessment of individual margins. The procedure may be performed safely with local anesthesia and/or monitored intravenous sedation. The need for open biopsy can usually be obviated by the use of CNB as described in Diagnostic Procedures.
Lumpectomy or wide local excision: Most often performed along with some form of lymph node dissection as part of a breast conservation procedure, lumpectomy involves excision of a palpable malignant breast lesion with adequate margins. In the case of nonpalpable lesions, a needle-localization procedure may precede lumpectomy. This is performed with ultrasonographic or mammographic assistance for nonpalpable, radiographically identified lesions. Following placement of a fine J wire under radiographic guidance, the lesion can be excised surgically. Care must be taken to obtain a solid core of breast tissue around the tip of the wire with margins of at least 1 cm. The specimen should be reevaluated radiographically to confirm excision of the intended lesion prior to completion of the operation.
Quadrantectomy: This is removal of an entire quadrant of the breast, which is less cosmetically satisfactory than lumpectomy.
Sentinel lymph node biopsy (SLNB): The sentinel lymph nodes (SLN) are the first nodes that receive drainage from tumors. The technique involves injecting radiocolloid, blue dye, or both in the tissues of the breast. Several techniques of injection are available, including subareolar, peritumoral, intradermal, or intraparenchymal. After injection, an incision is made with consideration of the potential need for subsequent completion lymph node dissection (see next paragraph). Therefore, the incision can be elongated easily if the SLN is positive for metastasis.
Completion Lymph Node Dissection (CLND): If an SLN is found to be positive on histologic evaluation, a CLND is indicated to assess the degree of lymph node involvement. This can have a significant impact on staging as well as adjuvant treatment.
