Oral cancer-causing HPV may spread through oral, genital routes

“HPV is the most common sexually transmitted disease in the world, and is a risk factor for several cancers, including cervical, vaginal, vulvar, oropharyngeal [throat/tonsil], anal, and penile cancer,” says Eduardo L. Franco, Professor and Director of the Division of Cancer Epidemiology at McGill University. “Understanding how HPV is transmitted is important because it will help us identify who is most at risk for HPV infection and how we can help them protect themselves and their partners,” adds Franco, who is also the Chairman of the Department of Oncology in the Faculty of Medicine. “Our work provides additional evidence that HPV is sexually transmitted to the oral tract through oral-oral and oral-genital contact.” Infection rates higher for male smokers A research team led by Franco looked at HPV infections in 222 men and their female partners and found that among men in the study, the prevalence of oral HPV was 7.2 percent…

Interstitial lung disease is significant risk factor for lung inflammation

ILD is a group of diseases that cause scarring and stiffing of the tissue and space around the air sacs in the lungs, which results in diminished gas exchange. The incidence of ILD among lung cancer patients is higher than in the general population as tobacco smoking is a common risk factor for both. Some lung cancer patients with ILD may not be considered good candidates for surgical therapy. …

Early palliative care can cut hospital readmissions for cancer patients

The Duke researchers shared their findings at the Palliative Care in Oncology Symposium sponsored by the American Society of Clinical Oncology. In the new treatment model, medical oncologists and palliative care physicians partnered in a “co-rounding” format to deliver cancer care for patients admitted to Duke University Hospital’s solid tumor unit. The Duke model fostered collaboration and communication between the specialists, who met several times a day to discuss patient care…

Circulating tumor cells provide genomic snapshot of breast cancer — ScienceDaily

“Counting the number of circulating tumor cells (CTCs) can tell us whether a patient’s cancer is aggressive, or whether it is stable and responding to therapy,” says the article’s first author Sandra V. Fernandez, Ph.D., assistant professor of Medical Oncology at Thomas Jefferson University. “Our work suggests that these cancer cells in the blood also accurately reflect the genetic status of the parent tumor or its metastases, potentially giving us a new and easy to source of genomic information to guide treatment.” First discovered for their diagnostic potential in 2004, circulating tumor cells are beginning to be used in the clinic to help guide treatment decisions and track a patient’s progress as the cancer progresses. …

Immunotherapy could stop resistance to radiotherapy — ScienceDaily

The researchers, based at The University of Manchester and funded by MedImmune, the global biologics research and development arm of AstraZeneca, and Cancer Research UK, found that combining the two treatments helped the immune system hunt down and destroy cancer cells that weren’t killed by the initial radiotherapy in mice with breast, skin and bowel cancers. Radiotherapy is a very successful treatment for many forms of cancer, but in cancer cells that it doesn’t kill it can switch on a ‘flag’ on their surface, called PD-L1, that tricks the body’s defences into thinking that cancerous cells pose no threat. The immunotherapy works by blocking these ‘flags’ to reveal the true identity of cancer cells, allowing the immune system to see them for what they are and destroy them…

Mesothelioma: New Findings On Treatment Options

“Mesothelioma remains a difficult disease to find better treatment options for, so we asked whether high-dose hemithoracic radiotherapy would decrease the rate or delay the time of local recurrence after chemotherapy and radical surgery,” says lead author Prof Rolf A. Stahel, from the Clinic and Policlinic for Oncology, at the University Hospital Zurich, Switzerland, and current President of the European Society for Medical Oncology. The multicentre trial included 153 patients with surgically-treatable malignant pleural mesothelioma, who were first treated with three chemotherapy cycles of cisplatin and pemetrexed, followed by surgical removal of affected lung tissue, with the goal of complete removal of the cancerous areas of lung. …

More than 70% of young oncologists in Europe suffer symptoms of burnout

“Oncology is an exceptionally rewarding career, but it can be demanding and stressful at times,” said Dr Susana Banerjee, lead author of the study and a consultant medical oncologist at The Royal Marsden NHS Trust in London, UK. “Oncologists make complex decisions about cancer management, supervise the use of toxic therapies, work long hours, and continually face patients suffering and dying,” she said…

Study adds to cancer-fighting promise of combined immunotherapy-radiation treatment

The study, led by Johns Hopkins Kimmel Cancer Center researchers, shows how in principle, radiation may specifically activate immune system cells responsible for attacking cancer cells, leading immune cells to “remember” how to fight cancer long after the cancer is gone. Andrew Sharabi, M.D., Ph.D., a resident in the Department of Radiation Oncology and Molecular Radiation Science at Johns Hopkins, is expected to present details of the study at the 2014 annual meeting of the American Society of Radiation Oncology (ASTRO) in San Francisco Sept. 15…
