New guidelines on radiation therapy for breast cancer patients

New guidelines issued by three leading cancer organizations suggest that more breast cancer patients should consider radiation therapy after a mastectomy.Overall, the guidelines say there's enough evidence to show radiation treatment after a mastectomy decreases the risk of breast cancer recurrence, and that even women with smaller tumors and three or fewer lymph nodes involved can benefit from the therapy."The new guidelines say there is clear evidence that the benefit of [post-mastectomy radiation therapy] extends to women with limited lymph node involvement," said Dr. Stephen Edge.

CAMBRIDGE, Mass., Sept. 19 (UPI) -- In addition to killing cancer with standard treatment options, researchers may have identified a method of preventing surviving cells from spreading to other parts of the body.Using a microRNA treatment as part of chemotherapy for treatment of breast cancer could prevent the disease from metastasizing, according to in a study published in the journal Nature Communications.Researchers at the Massachusetts Institute of Technology identified proteins that are important to cell migration and their process of invading otherwise healthy organs, successfully blocking their action and preventing the cellular processes in lab experiments and mice.

Gene therapy technique may help prevent cancer metastasis

The spread of malignant cells around the body, known as metastasis, is the leading cause of mortality in women with breast cancer.Now, a new gene therapy technique being developed by researchers at MIT is showing promise as a way to prevent breast cancer tumors from metastasizing.The treatment, described in a paper published today in the journal Nature Communications, uses microRNAs — small noncoding RNA molecules that regulate gene expression — to control metastasis.
