New breast cancer testing

A new molecular test test improves the accuracy of the search for cancer in the sentinel lymph nodes in the node biopsy, according to the results of the audit Saturday, researchers from San Antonio Breast Cancer Symposium.

The results of this study have shown that genes Search IFP-assay test, developed by Veridex LLC from the FDA in mid-July, about 10 percent more sensitive than conventional histology and microscopic examination in the search for signs of the tumor during a cell biopsy of the sentinel lymph nodes.

One of the challenges of the sentinel lymph node biopsy is a study of the pathology of the lymph nodes must be done, while off the operation to judge whether a tumor in the Sentinel nodes. Traditionally, a surgeon of sentinel lymph node biopsy with the elimination of less than 5 percent of the volume of lymph nodes during a stop in intra-operative surgery. The small knot is then frozen and examine under a microscope for the presence of cancer cells. When cancer cells are found in the nodes, the surgeon may remove from the rule during the biopsy of the lymph nodes.

But too often the result of this review are imprecise, the patient prior to the physical and emotional stresses of returning to the operating room for another surgical procedure of removing the lymph nodes for cancer cells.

The molecular genetic test Search trial, the FDA has approved as a substitute for the failure of the party froze method of examination of sentinel lymph node biopsy for one, it is a method ultra-fast, which is a Genetic testing for the detection of the search for tumor cells in lymph nodes During the intra-operative of the judgement of the surgery. Researchers report that this new technique is more sensitive frozen without particularity.
