Prostate cancer screening reduces deaths by a fifth: Large, long-term European trial

Despite this new evidence for the effectiveness of prostate-specific antigen (PSA) testing to reduce mortality, doubts as to whether the benefits of screening outweigh the harms remain, and routine PSA screening programmes should not be introduced at this time, conclude the authors. The European Randomised study of Screening for Prostate Cancer (ERSPC) began in 1993 to determine whether screening men for PSA reduces deaths from prostate cancer. …

Shingles vaccine remains effective after chemotherapy

Researchers examined the electronic health records of more than 21,000 Kaiser Permanente patients in Southern California who were 60 years of age and older and received chemotherapy between January 2007 and December 2012. Researchers found that those patients who were previously vaccinated with zoster vaccine were 42 percent less likely to develop shingles following chemotherapy. In addition, no vaccinated patients underwent hospitalization for shingles, while six unvaccinated patients were hospitalized with the disease, according to the study…

Bladder cancer patients identified who could benefit from ‘tumor-softening’ treatment — ScienceDaily

“This fascinating new finding could help doctors adapt their treatments to patients with bladder cancer,” said Nell Barrie, Cancer Research UK The team from The University of Manchester, funded by the Medical Research Council, found that patients whose bladder tumor had high levels of a protein, called ‘HIF-1α’, were more likely to benefit from having carbogen — oxygen mixed with carbon dioxide gas — and nicotinamide tablets at the same time as their radiotherapy. The treatment, called ‘CON’, makes radiotherapy more effective. By comparing levels of HIF-1α in tissue samples from 137 patients who had radiotherapy on its own or with CON, the researchers found the protein predicted which patients benefited from having CON. High levels of the protein were linked to better survival from the disease when patients had radiotherapy and CON. …

Protein ZEB1 promotes breast tumor resistance to radiation therapy — ScienceDaily

One protein with the even more out-there name of ZEB1 (zinc finger E-box binding homeobox 1), is now thought to keep breast cancer cells from being successfully treated with radiation therapy, according to a study at The University of Texas MD Anderson Cancer Center in Houston. …

Protein ZEB1 promotes breast tumor resistance to radiation therapy

One protein with the even more out-there name of ZEB1 (zinc finger E-box binding homeobox 1), is now thought to keep breast cancer cells from being successfully treated with radiation therapy, according to a study at The University of Texas MD Anderson Cancer Center in Houston. Li Ma, Ph.D., an assistant professor of experimental radiation oncology at MD Anderson, reported in this month’s issue of Nature Cell Biology that ZEB1 may actually be helping breast tumor cells repair DNA damage caused by radiation treatment by ramping up a first-line of defense known as DNA damage response pathway. …

Why we should vaccinate boys against HPV as well as girls

Gillian Prue, from the School of Nursing and Midwifery at Queen’s University of Belfast, says that the human papillomavirus (HPV) infection is common in men and can lead to genital warts and the development of some head and neck, anal or penile cancers. She says incidence of this has increased in the past two decades with HPV causing 5% of all human cancers. …

New drug target can break down cancer’s barrier against treatment

The team at Barts Cancer Institute, part of Queen Mary University of London, have found that a molecule, called focal adhesion kinase (FAK), signals the body to repair itself after chemotherapy or radiotherapy, which kill cancer cells by damaging DNA. When the researchers removed FAK from blood vessels that grew in melanoma or lung cancer models, both chemotherapy and radiation therapies were far more effective in killing the tumors. The researchers also studied samples taken from lymphoma patients. Those with low levels of FAK in their blood vessels were more likely to have complete remission following treatment. …

Lifestyle choices may affect long-term heart health of childhood cancer survivors

Adults who had cancer as children are known to be at increased risk for the metabolic syndrome, a group of risk factors that increases the likelihood of developing heart disease and other health problems such as diabetes and stroke. People with the metabolic syndrome have some combination of factors including high blood pressure, abnormal cholesterol and glucose levels, and increased body fat. …
