Researchers at Duke University Medical Center have created synthetic nanoparticles that target lymph nodes and greatly boost vaccine responses, said lead author Ashley St. John, Ph.D., a researcher at Duke-NUS Graduate Medical School. The paper was published online in the journal Nature Materials on Jan. 22. Currently all other adjuvants (substances added to vaccines to help to boost the immune response) are thought to enhance immunity at the skin site where the vaccine is injected...

Using two cell surface markers found to be highly expressed in breast cancer lymph node metastases, researchers at Moffitt Cancer Center, working with colleagues at other institutions, have developed targeted, fluorescent molecular imaging probes that can non-invasively detect breast cancer lymph node metastases. The new procedure could spare breast cancer patients invasive and unreliable sentinel lymph node (SLN) biopsies and surgery-associated negative side effects. Their study was...

Procedure may reduce recurrence rates, lower tumor marker levels Papillary thyroid cancer accounts for the majority of all thyroid malignancies, which primarily impact women. A new study indicates that routinely removing lymph nodes in the neck in these cancer patients may help prevent the disease from coming back. When thyroid cancer metastasizes, lymph nodes in the neck may be affected, but these lymph-node tumors can be tiny and may not be detected by ultrasounds done before surgery...

(Ivanhoe Newswire) -- The number of lymph nodes evaluated for colon cancer has risen significantly over the past two decades. However, according to a study in the September 14 issue of JAMA, this improvement is not associated with an increase in node-positive cancers. "Among patients surgically treated for colon cancer, several studies have demonstrated better survival for patients with more lymph nodes evaluated," according to background information in the study. The article goes on to...

But no corresponding rise in node-positive cancers During the past two decades there has been a significant increase in the percentage of patients who have a high number of lymph nodes evaluated during colon cancer operations, but this improvement is not associated with an increase in the overall proportion of colon cancers that are node positive, according to a study in the September 14 issue of JAMA. "As wide-ranging quality improvement efforts emerge throughout the health care...

Like humans, mice that live in their natural habitat encounter bacteria and other pathogens that exercise their immune system, yet the lab mice typically used in immunology studies are raised in isolation from most diseases. A study on natural killer cells in wild mice published this week in Molecular Ecology examines the hypothesis that the unsterile living conditions faced by humans and wild mice may improve the readiness of the immune system to fight new infections. The findings suggest...

(Ivanhoe Newswire) -- A new study shows removing lymph nodes because of the presence of microscopic cancer cells found in the sentinel node has no impact on survival among women with early-stage breast cancer. Researchers studied more than 5,000 women with breast cancer at 126 sites around the country. All the participants underwent breast-conserving surgery and sentinel lymph node dissection. The sentinel lymph node is the one that is closest to the tumor. Results showed survival outcomes...

Study refutes controversy about technique in delicate head, neck region A common technique for determining whether melanoma has spread can be used safely and effectively even in tumors from the head and neck area, according to a new study from the University of Michigan Comprehensive Cancer Center. Sentinel lymph node biopsy involves injecting a special dye to identify the first node where cancer would likely spread. If that node is clean, patients can avoid further debilitating surgery to...

Study reported in Journal of the American Medical Association A new study shows that removing lymph nodes due to the presence of occult, or microscopic, cancer cells found in the sentinel lymph node "“ the one closest to the tumor -- has no impact on survival outcomes of women with early-stage breast cancer. The principal investigator of the study is Armando E. Giuliano, MD, of Cedars-Sinai, who already is renowned for his clinical expertise and for his seminal research on lymph node...

There are many kinds of cancers of the immune system, but one, Activated B-Cell Diffuse Large B-Cell Lymphoma, or ABC-DLBCL, is particularly common and pernicious. Researchers at the University of Pennsylvania's School of Veterinary Medicine have shown for the first time that dogs that develop this disease spontaneously share the same aberrant activation of a critical intracellular pathway with humans. They also found that a drug designed to disrupt this pathway helps to kill tumor cells in...

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...
