Lymph Node News and Research

RSS

Lymph is clear or white fluid that travels through vessels, moves within tissues and work to keep all the parts of the body clean. After passing through the channels of the lymphatic system they drain into the lymph nodes. The lymph nodes act as filters along the lymphatic system. These nodes trap germs like bacteria, viruses, toxins as well as cancer cells and ensure that these are removed from the body.

TFF3 protein plays a more sinister role in breast cancer metastasis

The trefoil factor 3 (TFF3) protein protects and maintains the integrity of the epithelial surface in the normal breast. New research has found that while TFF3 protein expression is higher in well-differentiated low grade tumors and therefore associated with features of a good prognosis, it has a more sinister role in breast cancer invasion and metastasis.

Tissues in SIV-infected monkeys can ramp up production of Tregs

Tissue in monkeys infected with a close relative of HIV can ramp up production of a type of T cell that actually weakens the body's attack against the invading virus. The discovery, in lymph nodes draining the intestinal tract, could help explain how the HIV virus evades the body's immune defenses.

Aspirin-like drugs help prevent spread of tumors in the body

Australian scientists have made a breakthrough which could help in the fight against cancer. The team from Peter MacCallum Cancer Centre in Melbourne has found a link between non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin, and the ability of tumours to spread in the body. They say that doctors have been aware of the benefits of NSAIDs for many years, but did not fully understand the biological processes involved.

Postoperative radiotherapy does not really help elderly lung cancer patients

A controversial radiation treatment for patients who've had lung cancer surgery may not help elderly people live longer, U.S. researchers have found. Postoperative radiotherapy, or PORT, is thought to cut the chances that a tumor will return. But it can damage the heart and lungs, which might cancel out any potential benefits -- particularly in the elderly.

Radiation therapy may not benefit many older lung cancer patients

A new study has found that many older lung cancer patients get treatments that may not help them live longer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings suggest that physicians should not routinely use radiation after surgery to treat lung cancer that is advanced but has not widely spread, at least in older patients.

PORT may not prolong life in older people with NSCLC

Researchers from Mount Sinai School of Medicine have found that post-operative radiation therapy (PORT), a controversial yet frequently administered treatment for lung cancer, may not prolong life in older people with locally advanced disease.

Scientists discover ferocity of immune system after viral infection

A scientific team led by researchers at the University of Geneva (UNIGE) and the Charité Berlin Medical University has made a completely unprecedented discovery showing how much our immune system is provoked into action when confronted by viral intruders.

NIH, USDA and research facilities need to protect captive great apes

The Bioethics of Great Ape Well-Being: Psychiatric Injury and Duty of Care, recently published in the Animals & Society Institute's (ASI) Public Policy series, asserts that historically and to date the National Institutes of Health (NIH), U.S. Department of Agriculture (USDA), and research facilities have failed in their legal duty to protect captive great apes by not preventing foreseeable trauma of PTSD (Post Traumatic Stress Disorder) and other psychological injuries.

Silver as effective as leading chemotherapy drugs

The internet is awash with stories of how silver can be used to treat cancer. Now, lab tests have shown that it is as effective as the leading chemotherapy drug - and may have fewer side-effects.

Positive results from cisplatin plus radiation therapy trial on head and neck cancer

A select subgroup of advanced head and neck cancer patients treated with radiation therapy plus the chemotherapy drug cisplatin had more positive outcomes than patients treated with radiation therapy alone and continued to show positive results 10 years post-treatment, according to a study presented at the Multidisciplinary Head and Neck Cancer Symposium, sponsored by AHNS, ASCO, ASTRO and SNM.

Scientists connect two signature characteristics of pancreatic cancer

Scientists have connected two signature characteristics of pancreatic cancer, identifying a self-perpetuating "vicious cycle" of molecular activity and a new potential target for drugs to treat one of the most lehal forms of cancer.

Duke team creates vaccine adjuvant of nanoparticles that target lymph nodes

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.

Multiple sclerosis drug Gilenya under investigation by FDA and EMA

The US Food and Drugs Administration (FDA) and European Medicines Agency (EMA) are looking at the pros and cons of using Gilenya (fingolimod) in treating the neurological autoimmune disease Multiple Sclerosis (MS).

Matted lymph nodes may predict throat cancer metastasis

Researchers at the University of Michigan Health System have found a new indicator that may predict which patients with a common type of throat cancer are most likely have the cancer spread to other parts of their bodies.

New imaging probes can non-invasively detect breast cancer lymph node metastasis

Using two cell surface markers found to be highly expressed in breast cancer lymph node metastasis, 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 metastasis.

SonoPhoto Dynamic Therapy shows promise against squamous cell carcinoma

George Miller developed an ulcer on his bottom lip that began to bleed. His doctor sent cell scrapings to a pathologist, and diagnosed Miller with squamous cell carcinoma (SCC). According to TMD Limited, a medical tourism company, squamous cell carcinoma is the 2nd most common cancer in humans and other animals.

Breast implant rupture risk scrutinized and assessed in depth

According to Tim Goodacre, one of the members of the government-commissioned panel investigating the PIP breast implant scandal, the rupture rates found by the country’s biggest cosmetic surgery company were ‘unacceptable’. Mr. Goodacre, president of the British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS) and an Oxford University lecturer, said that if the panel confirmed the findings – in which almost one in 14 implants had leaked – then they should all be taken out in every case.

New initiative to detect cancers in earliest stages inside cells

A team of cancer imaging experts at Johns Hopkins has embarked on a five-year research initiative to speed development of early diagnostic tests and new treatments for breast, prostate and other common cancers.

FLT-PET imaging can effectively detect mantle cell lymphoma

Positron emission tomography (PET) and a molecular imaging agent that captures the proliferation of cancer cells could prove to be a valuable method for imaging a form of Non-Hodgkin's disease called mantle cell lymphoma, a relatively rare and devastating blood cancer.
