Tumor determination in bowel cancer: Blood test replaces surgery

One of the challenges of personalised medicine is the development of treatment resistance. At the Comprehensive Cancer Center (CCC) Vienna at the MedUni Vienna and Vienna General Hospital, a study is now commencing which involves patients with metastasized bowel cancer who are undergoing a new diagnostic method, namely liquid biopsy in the form of a blood test. The aim of this new method is to spot a tumor’s development of resistance early on and therefore adjust the treatment quickly and in a targeted manner…

Why patients respond to a life-saving melanoma drug

The study, led by UCLA Jonsson Comprehensive Cancer Center members Drs. Paul Tumeh and Antoni Ribas, primary investigator of pembrolizumab, is the first of its kind since the FDA approved the use of Keytruda in September and could lead the way for more effective use of the drug in patients with melanoma and other cancers. A protein known as PD-1 puts the immune system’s brakes on, preventing T cells from attacking cancer cells. Pembrolizumab removes the brake lines, freeing up the immune system to kill cancer cells. …

Body position in breast cancer radiation treatment matters, experts say — ScienceDaily

Dr. Julia White of Ohio State’s Comprehensive Cancer Center — James Cancer Hospital and Solove Research Institute has helped develop a modified treatment board that allows patients to lie comfortably on their stomachs while the breast tissue falls away from the chest wall, allowing the radiation to target the cancer. Traditionally, women who undergo radiation therapy lie on their backs in the supine position. …

Survival molecule helps cancer cells hide from the immune system

A new study by researchers at The Ohio State University Comprehensive Cancer Center — Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC — James) shows that a molecule called nuclear factor kappa B (NF-kB) helps cancer cells by suppressing the immune system’s ability to detect and destroy them. …

Novel drug action against solid tumors explained — ScienceDaily

Their paper, published in Proceedings of the National Academy of Sciences, is the culmination of nearly a decade of research into the role of arginine — and its deprivation — in the generation of excessive autophagy, a process in which the cell dies by eating itself. Study co-author Hsing-Jien Kung, a cancer biologist and UC Davis professor emeritus who now leads the National Health Research Institutes in Taipei, Taiwan, first discovered the mechanism by which arginine deprivation works in 2009, when he led basic science research at the UC Davis Comprehensive Cancer Center. “Traditional cancer therapies involve ‘poisoning’ by toxic chemicals or ‘burning’ by radiation cancer cells to death, which often have side effects,” Kung said…
