Medical scientists in Germany say they've determined that ultrasound signals can be used to determine if cancer has started to spread in melanoma patients. Dr. Christiane Voit of the Medical University of Berlin said the discovery enables physicians to decide how much surgery, if any, is required and to predict a patient's probable survival. We have identified two ultrasound patterns of lymph node metastasis in melanoma patients, which can identify correctly any amount of tumor cells in the...

Patients could be spared unnecessary surgery Researchers have shown for the first time that patterns of ultrasound signals can be used to identify whether or not cancer has started to spread in melanoma patients, and to what extent. The discovery enables doctors to decide on how much surgery, if any, is required and to predict the patient's probable survival. Dr Christiane Voit told Europe's largest cancer congress, ECCO 15 "“ ESMO 34 [1], in Berlin today (Wednesday 23 September): "We...

Many studies favor an extended lymphadenectomy at the time of a potentially curative gastrectomy for node-positive gastric cancer, and the risk of long-term death tends to decrease when the number of resected lymph nodes increases to about 25. However, few studies have assessed the relative contribution of the total number of resected lymph nodes to the outcome of patients with node-negative gastric cancer. Further studies are needed to know how the numbers of dissected LNs may affect the...

If we imagine our immune system to be a police force for our bodies, then previous work has suggested that the Lymph nodes would be the best candidate structures within the body to act as police stations "“ the regions in which the immune response is organized. However, Prof. Burkhard Becher, University of Zurich, suggests in a new paper "“ published in this week's issue of PLoS Biology "“ that lymph nodes are not essential in the mouse in marshalling T-cells (a main immune...

A new phase III clinical trial of early stage breast cancer patients has shown that a molecule designed to home in on nearby lymph nodes is just as accurate as current techniques, but faster, more specific and easier to use. "These results will really enable molecular biology to enter the operating room for lymph node detection," said breast surgeon Anne Wallace, MD, professor of clinical surgery at the UC San Diego School of Medicine and the Moores UCSD Cancer Center, and one of the study...

St. Jude study shows the Prox1 gene is a two-way switch that, if turned off, causes lymphatic endothelial cells to be reprogrammed so that they lose their identity and become more like blood endothelial cells MEMPHIS, Tenn., Dec. 1 /PRNewswire-USNewswire/ -- Scientists at St. Jude Children's Research Hospital have discovered that a certain differentiated cell type is so ready to change its identity that it requires the constant expression of a gene called Prox1 to dissuade it. The...

U.S. researchers suggest standard radiation therapy for some breast cancer patients may not be medically required and cause unnecessary side effects. "When a woman has a tumor greater than 5 centimeters and negative lymph nodes, a mastectomy followed by radiation is recommended," Dr. Penny Anderson of the Fox Chase Cancer Center in Philadelphia. "We typically irradiate the chest wall because it's been shown to improve survival. Out of an abundance of caution, many radiation oncologists also...

A new study on Tuesday suggests almost two-thirds of hospitals fail to check colon cancer patients well enough for signs that their tumor is spreading. Doctors should examine at least 12 lymph nodes to figure out whether colon cancer has metastasized -- spread to other parts of the body -- and to accurately diagnose the stage, or severity, of the cancer, Leading medical organizations said. Such information helps guide future treatment, including whether a patient with metastatic cancer gets...

A new test that examines large sections of the sentinel lymph node for genes expressed by breast cancer could reduce the risk of recurrence and multiple surgeries, doctors say.The GeneSearch Breast Lymph Node Assay, manufactured by Veridex, L.L.C., a Johnson & Johnson company, is being used at the Medical College of Georgia to examine half of the tissue in the sentinel lymph node, the first place breast cancer typically spreads. The sample represents more than 10 times the amount of...

A lymph node is an immune system organ that is widely distributed throughout various places in the body. There are about 500-600 nodes in an individual adult, with clusters of lymph nodes found in the underarms, groin, neck, chest, and abdomen. The lymphatic system as a whole is responsible for acting as the body’s primary mechanism of defense. Each node is oval-shaped, and measures between a few millimeters and a few centimeters long. They are linked to one another by lymphatic vessels and...
