New classification system for tumors can guide diagnosis and treatment options for cancer
Based on the largest study of cancer patients of its kind, scientists have created a new way of classifying tumours. Clinicians can use genome sequencing to assign their patients’ tumours to one of sixteen groups in the new classification system, ten of which provide important information for the diagnosis and treatment of the disease, like whether an...

Live zoster vaccine safe and effective for people taking TNF inhibitors
AMERICAN COLLEGE OF RHEUMATOLOGY ATLANTA — According to new research findings presented this week at the 2019 ACR/ARP Annual Meeting, the live zoster virus vaccine is safe for people who are currently receiving tumor necrosis factor inhibitor (TNFi) biologic therapies for various indications (Abstract # 824). In healthy individuals, excess TNF in the blood is...

Tumors alone may be linked to cancer patients’ cognitive problems
by Emily Caldwell, The Ohio State University New research suggests that both tumors and chemotherapy could be linked to the cognitive problems experienced by cancer patients because each affects the circadian clock, throwing off cellular processes related to behavior and memory. Scientists found that mice with breast cancer tumors were less likely than healthy mice...

Drug that targets key mutation found to shrink some tumors
by Bob Yirka , Medical Xpress A team of researchers affiliated with several institutions in the U.S. and Australia (and sponsored by pharmaceutical company Amgen Research) has found that a drug they optimized to target a protein produced due to mutations in the genome was able to shrink some tumors in mice and humans. In...

Scientists reveal novel oncogenic driver gene in human gastrointestinal stromal tumors
CHINESE ACADEMY OF SCIENCES HEADQUARTERS Sarcomas – cancers that arise from transformed mesenchymal cells (a type of connective tissue) – are quite deadly. Gastrointestinal stromal tumors (GISTs) are the most common human sarcoma and are initiated by activating mutations in the KIT receptor tyrosine kinase. Micro-GISTs are a smaller variation of clinical GISTs and are...

Light Activated Compound Kills Hypoxic Tumors
SEPTEMBER 27TH, 2019 MEDGADGET EDITORS MEDICINE, NANOMEDICINE, ONCOLOGY Photodynamic therapy is a technique that relies on photosensitizer chemicals to generate reactive species that kill cancer cells. These compounds can be delivered into tumors and then light is used to activate them. One of the main reasons for the slow adoption of this technology is that...

Natural killers’ may help treat advanced solid cancerous tumors
by Chris Adam, Purdue University An internal battle over oxygen can lead to major setbacks for people battling solid malignant tumors such as lung and brain cancers. Many solid tumors develop a severe lack of oxygen because they grow into large masses where the blood supply becomes progressively impaired. Cancer cells have adapted to grow in these situations, but immune cells have...

Scientists find potential ‘magic bullet’ for treating tumours
Posted Today Researchers have found a therapy to reduce the size of tumours where previous drugs have failed. Tumours develop from abnormal cells in the body that continue to grow forming lumps. These lumps can be benign, meaning they’re not harmful, or they can become malignant which leads to cancer. Malignant tumours, become infiltrated by...

Shrinking brain tumours and opening the door for targeted cancer therapies
by University of Portsmouth A new drug, known as IP1867B, could be used for future treatments of brain tumours. Dr. Richard Hill led the research team at the Brain Tumour Research Centre at University of Portsmouth, working with the University of Algarve (Portugal), the University of Liverpool (UK) and Innovate Pharmaceuticals to examine IP1867B. The research team showed that IP1867B...
