Why won’t our doctors face up to the dangers of radiotherapy?

Source: http://www.dailymail.co.uk/health/article-1089091/Why-wont-doctors-face-dangers-radiotherapy.html Author: Isla Whitcroft It's a life-saver for thousands - but the side-effects can be devastating. A year after he'd undergone treatment for cancer of the tonsils, Richard Wayman felt a painful tingling in his legs. Within weeks, the 59-year- old shopkeeper was struggling to walk. He was admitted to hospital, where doctors carried out scans, X-rays and tests. 'The scans revealed lesions on my lungs, which raised fears that the cancer had spread, so I was admitted to another hospital for a biopsy and, as a result, contracted MRSA and pneumonia,' recalls Richard, from Colchester in Essex. 'From 11-and-a-half stone I went down to eight-and-a-half stone. I thought I was never going to get out of there.' Finally, the lung lesions were diagnosed as a side-effect of the radiotherapy Richard had undergone for his cancer. However, his problems only got worse: a few weeks after a routine tooth extraction, the bone around the extraction started to crumble and become infected. Within months he had an open weeping wound, running from his lower cheek through his jaw and into his mouth. The diagnosis: bone necrosis as a direct result of radiotherapy damage to the jaw. Richard is one of the many thousands of cancer survivors who have developed terrible conditions as a result of the radiotherapy treatment that helped save them. Around 4 to 5 per cent of all head and neck cancer patients suffer problems with swallowing or breathing, fistulas (open holes) in the jaw and gum, loss [...]

Hog jowls and clementines: A bid to awaken cancer patients’ ruined sense of taste

Source: www.statnews.com Author: Eric Boodman The medicines were rich and strange, their active ingredients so particular they sounded fictional. Credit: Molly Ferguson for Stat One regimen involved jowl bits from Red Wattle hogs; the pigs were bred from sows named Fart Blossom and Hildegard, and had spent the end of their lives gorging on acorns, hickory nuts, apples, and black walnuts. Another experimental drug included the flesh of the Ubatuba pepper, picked when it was red as a Santa suit, dried at precisely 90 degrees for five days, and then pulverized, seeds and all, into a fragrant, pinkish powder. These concoctions were meant to be therapeutic — but they hadn’t been devised by pharmacologists or biochemists or even lab techs. Their inventors had no scientific training whatsoever: They were celebrity Montreal chef Frédéric Morin and renowned Atlanta pastry-maker Taria Camerino, who would be facing off in an unusual culinary duel. They’d been challenged to help solve a problem that most clinicians and neuroscientists aren’t able to — the impairment of taste in cancer patients who undergo chemotherapy and radiation. This cook-off in the University of Kentucky’s demo kitchen was the opener for the second annual Neurogastronomy Symposium, which was born over a boozy, late-night chance encounter between neuropsychologist Dan Han and Morin in the chef’s restaurant. Together, they envisioned a conference that would combine neuroscience, agriculture, history, nutrition, medicine, and cooking — to understand the art and science of why we eat what we eat, and how we [...]

Oral cancer in the crosshairs at San Antonio Dental School

Source: tpr.org Author: Wendy Rigby San Antonio researchers are working on a new therapy for a stealthy killer: oral cancer. Visits to the dentist are your number one protection against the disease. In a lab at the University of Texas Health Science Center at San Antonio, dental researcher Cara Gonzales, DDS, Ph.D., shared promising news on a new approach to healing. "It was very exciting," Gonzales said. "These patients have not had any new therapeutic options in 40 years." The discovery of a new gene that’s turned on in oral cancers gave Gonzales and her colleagues a new target at which to aim. It’s a gene that’s also found in lung cancers. So-called nude mice are used in the oral cancer experiments. Wendy Rigby / Texas Public Radio Gonzales works in a sprawling space filled with lab equipment and cell lines used in many molecular biology projects. One of her research assistants brought in a cage of lab animals with some strange lumps on their backs. "These are called nude mice because they don’t have a complete immune system," Gonzales explained. These mice are at the center of a successful experiment. First, scientists used human oral cancer cells to grow large tumors on the animals. They tried one oral cancer drug already on the market. Not much action. Then, they tried a lung cancer drug, also already approved by the Food and Drug Administration. Not that effective on its own. Finally, they used a combination of two drugs. [...]

Particular HPV strain linked to improved prognosis for throat cancer

Source: medicalxpress.com Author: provided by University of North Carolina Health Care When it comes to cancer-causing viruses like human papillomavirus, or HPV, researchers are continuing to find that infection with one strain may be better than another. In an analysis of survival data for patients with a particular type of head and neck cancer, researchers from the University of North Carolina Lineberger Comprehensive Cancer Center confirmed findings that a particular strain of HPV, a virus linked to a number of cancers, resulted in better overall survival for patients with oropharyngeal cancer than patients with other strains of the virus in their tumors. They believe their findings, reported in the journal Oral Oncology, are particularly important as physicians move to lessen treatment intensity for patients with HPV-linked oropharyngeal cancer in clinical trials to try to spare them negative side effects of radiation or drugs. They also found that a test used widely to determine patients' HPV status may not be sensitive enough to select patients for de-intensification. "What we demonstrate in this study is that the type of HPV can help us to better determine a patient's prognosis," said the study's senior author Jose P. Zevallos, MD, MPH, an associate member of UNC Lineberger and an associate professor in the UNC School of Medicine. "We think this is important because HPV positive patients do so well generally, and there's been a huge move nationally to take treatment down a couple notches to limit morbidity and side effects. The risk is that [...]

Men with throat cancer will soon outnumber women with cervical cancer In The US

Source: www.houstonpublicmedia.org Author: Carrie Feibel The national increase in cases of oropharyngeal cancer related to the human papilloma virus is troubling, because there is no screening test to catch it early, like the Pap test for cervical cancer. The oropharynx is the area of the throat behind the mouth, and includes the tonsils and the base of the tongue. Oropharyngeal cancer is increasing in both men and women, but for reasons that aren’t well understood, male patients are outnumbering female patients by five to one, according to Dr. Erich Sturgis, a head and neck surgeon at MD Anderson Cancer Center. “It’s usually a man, and he notices it when he’s shaving. He notices a lump there,” Sturgis said. “That lump is actually the spread of the cancer from the tonsil or the base of the tongue to a lymph node. That means it’s already stage three at least.” In the U.S., the number of oropharyngeal cancers caused by HPV are predicted to exceed the number of cervical cancers by 2020, Stugis said. “With cervical cancer, we’ve seen declining numbers well before we had vaccination, and that’s due to the Pap smear being introduced back in the late 50s,” he said. “But we don’t have a screening mechanism for pharynx cancer.” Research on an effective screening test for early-stage pharynx cancer is still underway. The reasons for the disproportionate effect on men are unknown. One theory is that people are engaging in more oral sex, but that doesn’t explain why men [...]

Cancer-Preventing Vaccines Given To Less Than Half Of US Kids

Source: www.houstonpublicmedia.org Author: Carrie Feibel U.S. regulators approved a vaccine to protect against the human papilloma virus (HPV) in 2006, but cancer experts say misconceptions and stigma continue to hamper acceptance by both doctors and parents. Eighty percent of Americans are exposed to the human papilloma virus in their lifetimes. Some strains of HPV can cause genital warts, but most people experience no symptoms and clear the virus from their systems within a year or two. But for an unlucky minority, the virus causes damage that, years later, leads to cervical cancer, throat cancer, and other types. Researchers at MD Anderson are frustrated that ten years after the first vaccine arrived on the market, only 42 percent of U.S. girls, and 28 percent of boys, are getting the three-shot series. The series can be given to girls and boys between the ages of 9 and 26, but the immune response is strongest at younger ages, before sexual activity begins. n 2007, then-Texas governor Rick Perry proposed making the HPV vaccine mandatory for all preteen girls.  At the time, the vaccine was only approved and marketed for girls. Dr. Lois Ramondetta, a cervical cancer specialist at MD Anderson, remembers the outcry. “A lot of people felt that was the right idea, but the wrong way to go about it. Nobody really likes being told what to do, especially in Texas,” Ramondetta said. “I think there was a lot of backlash.” Eventually, the legislature rejected Perry’s plan, even though it included an opt-out [...]

Incisionless robotic surgery offers promising outcomes for oropharyngeal cancer patients

Source: medicalxpress.com Author: press release, Henry Ford Health System A new study from researchers at Henry Ford Hospital finds an incisionless robotic surgery – done alone or in conjunction with chemotherapy or radiation – may offer oropharyngeal cancer patients good outcomes and survival, without significant pain and disfigurement. Patients with cancers of the base of tongue, tonsils, soft palate and pharynx who underwent TransOral Robotic Surgery, or TORS, as the first line of treatment experienced an average three-year survival from time of diagnosis. Most notably, the study's preliminary results reveal oropharyngeal cancer patients who are p16 negative – a marker for the human papilloma virus, or HPV, that affects how well cancer will respond to treatment – have good outcomes with TORS in combination with radiation and/or chemotherapy. "For non-surgical patients, several studies have shown that p16 positive throat cancers, or HPV- related throat cancers, have better survival and less recurrence than p16 negative throat cancers," says study lead author Tamer Ghanem, M.D., Ph.D., director of Head and Neck Oncology and Reconstructive Surgery Division in the Department of Otolaryngology-Head & Neck Surgery at Henry Ford Hospital. "Within our study, patients treated with robotic surgery had excellent results and survival, irrespective of their p16 status." Study results will be presented Sunday, Sept. 18 at the 2016 American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) annual meeting in San Diego. Led by Dr. Ghanem, Henry Ford Hospital in Detroit was among the first in the country to perform TORS using the da [...]

Expert says Nivolumab Poised to Change Standard of Care in SCCHN

Source: www.onclive.com Author: Laura Panjwani Nivolumab (Opdivo) is a game-changing agent for the treatment of patients with squamous cell carcinoma of the head and neck (SCCHN), according to Robert L. Ferris, MD, PhD. “Recent findings have shown us that this agent is really the new standard-of-care option for all platinum-refractory patients with head and neck cancer,” says Ferris, vice chair for Clinical Operations, associate director for Translational Research, and co-leader of the Cancer Immunology Program at the University of Pittsburgh Cancer Institute. “This is regardless of whether patients are PD-L1–positive or negative or whether they are HPV-positive or negative.” The PD-L1 inhibitor received a priority review designation by the FDA in July 2016 based on the CheckMate-141 study, which demonstrated a median overall survival (OS) with nivolumab of 7.5 months compared with 5.1 months with investigator's choice of therapy (HR, 0.70; 95% CI, 0.51-0.96; P = .0101) in patients with recurrent or metastatic SCCHN. The objective response rate (ORR) was 13.3% with nivolumab and 5.8% for investigator's choice. The FDA is scheduled to make a decision on the application for the PD-1 inhibitor by November 11, 2016, as part of the Prescription Drug User Fee Act. Ferris was the lead author on an analysis that further evaluated preliminary data from CheckMate-141, which was presented at the 2016 ASCO Annual Meeting. In an interview with OncLive, he discusses the findings of this study, potential biomarkers for nivolumab, and questions that remain regarding the use of the immunotherapy in SCCHN.

New study analyzes physical therapy for head and neck cancer survivors

Source: www.curetoday.com Author: Andrew J. Roth The aftermath of treatment for head and neck cancer can be particularly difficult, according to Ann Marie Flores. Flores, assistant professor, Department of Physical Therapy, Movement & Rehabilitation Science, Bouvé College of Health Sciences, Northeastern University, conducted a pre-pilot study looking at early physical therapy education for this patient population. CURE interviewed Flores about her poster, which she presented at the 8th Biennial Cancer Survivorship Research Conference in Washington, DC. Could you first give some background about this study? How did it come to be? It was a spinoff of some studies that I began in breast cancer. I conducted a literature review of rehab needs of breast cancer survivors about 10 years ago and found that there was very little out there. Then, when I started a rehab oncology program at a previous institution, the patient population that were referred to the program tended to not be breast cancer patients, because they physically and functionally tend to do well in aggregate. Most of my patients referred were those with head and neck cancer. I went through the same process to look through literature critically to figure out what exists in terms of physical therapy and rehabilitation-based approaches. I've updated this over a long period of time and this poster is a systematic review of the quality of evidence. I combined this literature and data review with talking to a focus group of cancer survivors. What did you find? I asked the focus group [...]

Heading back to the office following head and neck cancer

Source: blogs.biomedcentral.com Author: Daniel Caley In Cancers of the Head & Neck launching today publishes the first study looking at disability and employment outcomes in patients with head and neck cancer related to the human papillomavirus (HPV). Dr Shrujal Baxi, Section Editor for survivorship and patient related outcomes and author of this study, explains more about their work in this Q&A: The rates of patients diagnosed with HPV-related head and neck cancer is rising annually. By 2020, there will be more cases of HPV-related head and neck cancer than HPV-related cervical cancer in the United States. Numerous studies have shown that most patients with this diagnosis are likely to be cured of their disease, placing an increased emphasis on quality of life and non-cancer outcomes in this population of survivors. The majority of patients diagnosed with HPV-related head and neck cancer are working-age adults and employment is a serious issue both financially and psychologically. How can treatment for head and neck cancer impact employment? Treatment for head and neck cancer often involves a combination of chemotherapy and radiation given over a six to seven week period, often known as concurrent chemoradiation or combined modality chemoradiation. This process is considered toxic and can impact a patient’s ability to function normally including speaking, chewing, breathing and swallowing. Many patients require numerous supportive medications to get through treatment including narcotics for pain and anti-nausea medications. Patients can lose on average 10-15% of their weight within a few months and can suffer from severe [...]
