Blood and saliva tests help predict return of HPV-linked oral cancers

“There is a window of opportunity in the year after initial therapy to take an aggressive approach to spotting recurrences and intensively addressing them while they are still highly treatable,” says Joseph Califano, M.D., professor of Otolaryngology — Head and Neck Surgery, member of the Johns Hopkins Kimmel Cancer Center, and medical director of the Milton J. Dance Jr. Head and Neck Center at the Greater Baltimore Medical Center. “Until now, there has been no reliable biological way to identify which patients are at higher risk for recurrence, so these tests should greatly help do so,” he adds. …

‘Normal’ bacteria vital for keeping intestinal lining intact

The research involved the intestinal microbiome, which contains some 100 trillion bacteria. The role of these microorganisms in promoting or preventing disease is a major emerging field of study. Einstein scientists found that absorption of a specific bacterial byproduct is crucial for maintaining the integrity of the intestinal epithelium — the single-cell layer responsible for keeping intestinal bacteria and their toxins inside the gut and away from the rest of the body…

‘Rewired’ mice show signs of longer lives with fewer age-related illnesses

In healthy cells, TRAP-1 is an important regulator of metabolism and has been shown to regulate energy production in mitochondria, organelles that generate chemically useful energy for the cell. In the mitochondria of cancer cells, TRAP-1 is universally overproduced. The Wistar team’s report, which appears in the journal Cell Reports, shows how “knockout” mice bred to lack the TRAP-1 protein compensate for this loss by switching to alternative cellular mechanisms for making energy…

Cancer mutations identified as targets of effective melanoma immunotherapy

“This study provides the technical solution to identify mutated tumor targets that can stimulate immune responses, which is one of the major bottlenecks in developing a new generation of adoptive T-cell therapy,” said Steven A. Rosenberg, MD, PhD, chief of surgery at the National Cancer Institute (NCI) in Bethesda, Maryland. “The two targets identified in this study play important roles in cancer cell proliferation…

High-tech ‘whole body’ scan could improve treatment of bone marrow cancer

The new type of magnetic resonance imaging (MRI) scan could improve care for a type of cancer called myeloma and reduce reliance on bone marrow biopsies, which can be painful for patients and often fail to show doctors how far the disease has spread. The research is published today in the journal Radiology and was carried out by researchers at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Trust. It received funding from Cancer Research UK and the National Institute for Health Research Clinical Research Facility in Imaging, with additional funding from the EPSRC. The new whole-body, diffusion-weighted MRI scans showed the spread of cancer throughout the bone marrow of patients with myeloma — one of the most common forms of blood cancer — more accurately than standard tests…

People with HIV with early-stage cancers are up to four times more likely to go untreated for cancer

Life expectancy for HIV-infected people is now similar to uninfected people, but survival for HIV patients who develop cancer is not. While many studies have attempted to understand why HIV-infected cancer patients have worse outcomes, the new study, the largest of its size and scope, examined differences in cancer treatment as one potential explanation. For early-stage cancers that have the highest chance of cure with appropriate treatment, those with HIV were twice to four times as likely to not receive appropriate cancer treatment, the researchers found…
