But there’s no difference if simple compression bandages or a complicated daily lymphatic massage are used as treatment, McMaster University researchers have found. "In the future, patients who receive or can only afford elastic sleeves and gloves should be comforted knowing that their care has not been compromised," said Dr. Ian Dayes, associate professor of oncology for the Michael G…

Now, a team of researchers led by Mei R. Fu, PhD, RN, ACNS-BC, associate professor of Chronic Disease Management at the New York University College of Nursing (NYUCN), offers supporting evidence for using Bioelectrical Impedance Analysis (BIA) ratios to assess Lymphedema. The study, "L-DEX Ratio in Detecting Breast Cancer-Related Lymphedema: Reliability, Sensitivity, and Specificity," published in Lymphology, argues because the low frequency electronic current cannot travel through cell membranes, it provides a direct measure of lymph fluid outside the cells. This allows for a more accurate assessment of lymphedema using a Lymphedema Index named L-Dex ratio. …
The instrument is a modified wide-bore 600-megahertz magnetic resonance imaging spectrometer that will be equipped with a custom imaging probe. …
tumors with lower levels of oxygen — known as hypoxia — often respond less well to radiation therapy. There are several agents that can be given to patients before radiotherapy to reduce hypoxia, but these are not given as standard. Being able to measure how well-oxygenated an individual’s tumor is would give doctors a valuable way of identifying which patients might benefit from treatment with hypoxia reducing agents before radiotherapy. Hypoxia has previously been investigated by looking at the expression of certain genes, and Manchester researchers have come up with a genetic profile for tumors that should indicate the overall level of oxygenation…
Nanoparticles are just as small, or even smaller, than many blood proteins. …
Colorectal cancer is the third most commonly diagnosed type of cancer worldwide in men and the second in women, and it is also the third most common cause of death. In approximately 50 percent of patients, metastases to the liver are present at diagnosis or during follow-up, which account for a large portion of morbidity and mortality in patients…
A new study from MIT and the University of Toronto offers a possible way to overcome that resistance. The researchers found that when cisplatin was delivered to cellular structures called mitochondria, DNA in this organelle was damaged, leading to cancer cell death. …
"We know very little about male breast cancer since it comprises only 0.6 percent of all breast cancer, and nearly all therapy is based on female breast cancer studies. This study demonstrates that just as in women, men with early stage breast cancer have the same outcome with a mastectomy or a lumpectomy followed by radiation. In women, breast-conserving surgery is the standard and preferred treatment for the majority of women…
Scientists at The Institute of Cancer Research, London, found that combining two separate molecularly targeted therapies could stop processes driving growth in a cancer called rhabdomyosarcoma, a major cause of cancer death in children. The drugs, called AZD8055 and AZD6244, block two different signalling pathways involved in cancer growth — acting like road-blocks on two separate routes that cancers could otherwise use to evade treatment. The study, published in Clinical Cancer Research, was funded by the NIHR Biomedical Research Centre for Cancer at The Royal Marsden NHS Foundation Trust and The Institute of Cancer Research (ICR), with additional funding from Cancer Research UK, The Royal Marsden Hospital Charitable Fund and the Chris Lucas Trust. Rhabdomyosarcoma tumours can form anywhere in the body and resemble primitive muscle tissue…
