Epigenetic modification discovered in adult throat cancers

Source: www.specialtypharmacytimes.com Author: Lauren Santye, Assistant Editor An epigenetic modification may be the cause of 15% of adult head and neck cancers that are linked to tobacco and alcohol use, according to a study published in Nature Genetics. Although the body is made up of a large number of different types of cells––neurons, skins cells, fat cells, immune cells–– they all have the same DNA or genome. It was not until recently that scientists discovered their differences can be explained by epigenetics. “This discovery was absolutely unexpected since it seemed highly improbable that the kind of alterations of the epigenome that we had previously found in other types of tumors in children and young adults could also target an epithelial tumor like throat cancer that occurs only in adults,” said Dr Nada Jabado. There are already some promising drug molecules currently on the market for other diseases that could be tested for head and neck cancers, as well as other cancer types, according to the study. Additionally, the investigators hope that the findings could help in developing treatments for pediatric patients. “Now that we’ve identified this cohort of patients, we can move quite quickly since the case of adults, as opposed to children, there are more patients and lots of clinical trials,” Dr Jabado said. “The medicines could then be tested on children afterward.” Dr Jabado’s work focuses on epigenetics in pediatric cancers, particularly on the mutations of the histone H3 protein. In particular, the investigators were interested in a [...]

Cancer patients sometimes can’t get coverage at the hospitals they want

Source: Washington Post Author: Michelle Andrews Published: January 15 Getting cancer is scary. Discovering that your health plan doesn’t give you access to leading cancer centers may make the diagnosis even more daunting. As insurers participating in the health marketplace shrink their provider networks and slash the number of plans that offer out-of-network coverage, some consumers with cancer are learning that their treatment options can sometimes be limited. One reader wrote to Kaiser Health News last month saying that she was dismayed to learn that none of the plans offered on the New York marketplace provides access to Memorial Sloan Kettering Cancer Center in New York, where she is a patient. Memorial Sloan Kettering is a well-regarded cancer center that is affiliated with the National Comprehensive Cancer Network and the National Cancer Institute.It participates in New York’s Essential Plan, which is available to lower-income people but not to people enrolling in plans with the familiar categories of bronze, silver, gold and platinum. NCCN is an alliance of 27 cancer centers whose physicians and researchers develop clinical practice guidelines that are widely respected. The National Cancer Institute’s 69 designated cancer centers, which are recognized for their scientific leadership and research, can offer patients access to cutting-edge treatments and clinical trials. A 2015 survey found that three-quarters of NCI-designated cancer centers said they participated in at least some exchange plans, and 13 percent said they were included in all exchange plans in their state. Among centers that didn’t participate in any exchanges, [...]

FDA Warns Against So-Called “Cancer Cure”

Source: http://www.curetoday.com/articles/fda-warns-against-socalled-cancer-cure Published: 01/13/2017 Author: BRIELLE URCIUOLI The US Food and Drug Administration (FDA) just added another agent, PNC-27, to the growing list of drugs that falsely claim to treat or cure cancer. An FDA lab recently found the bacteria Variovorax paradoxus in PNC-27, a product that is claiming to treat and cure all cancers, claiming to affect lung cancer as affectively as head and neck cancer. Though no illness or serious adverse events were reported to the FDA, contact with contaminated samples can lead to life-threatening infections, especially in vulnerable populations, such as young children, elderly people, pregnant women and people who have weakened immune systems, according to a statement released by the FDA. “In general, consumers should be cautious of products marketed and sold online claiming to treat, cure or prevent any disease. Products claiming to treat, cure or prevent disease, but are not proven safe and effective for those purposes not only defraud consumers of money, they can lead to delays in getting proper diagnosis and treatment of a potentially serious condition,” Kristofer Baumgartner, FDA spokesperson, said in an interview with CURE. PNC-27 is being dosed in multiple ways, such as a nebulized solution, intravenous solution, vaginal suppository or rectal suppository. The FDA is urging people not to purchase or use PNC-27, which is neither FDA evaluated or approved. Patients should consult with their licensed health care providers before deciding on a treatment plan, and if they have already taken PNC-27, they should see their doctor as [...]

NCI-Designated Cancer Centers Issue Statement in Support of New CDC Recommendations on HPV Vaccination

Source: The ASCO Post Posted: 1/11/2017 The 69 National Cancer Institute (NCI)-designated cancer centers have issued a joint statement in support of recently revised recommendations from the Centers for Disease Control and Prevention (CDC) to improve national vaccination rates for human papillomavirus (HPV). According to the CDC, incidence rates of HPV-associated cancers have continued to rise, with approximately 39,000 new HPV-associated cancers now diagnosed each year in the United States. Although HPV vaccines can prevent the majority of cervical, anal, oropharyngeal, and other genital cancers, vaccination rates remain low across the United States, with just 41.9% of girls and 28.1% of boys completing the recommended vaccine series. New Recommendations The new guidelines from the CDC recommend that children under age 15 should receive 2 doses of the 9-valent HPV vaccine at least 6 months apart. Adolescents and young adults older than 14 should continue to complete the 3-dose series. Research shows there are a number of barriers to overcome to improve vaccination rates, including a lack of strong recommendations from physicians and parents not understanding that this vaccine protects against several types of cancer. In an effort to overcome these barriers, NCI-designated cancer centers have organized a continuing series of national summits to share new research, discuss best practices, and identify collective action toward improving vaccination rates. The original joint statement, published in January 2016, was the major recommendation from a summit hosted at The University of Texas MD Anderson Cancer in November 2015, which brought together experts from the [...]

Artificial larynx implant helps throat cancer patient breathe and speak

Source: www.ctvnews.ca Author: staff Sixteen months after receiving an artificial larynx, a 56-year-old French man suffering from throat cancer can now whisper and breathe normally. A report published this week in the New England Journal of Medicine considers this to be a significant first achievement. Thanks to the implant, a 56-year-old throat cancer patient can now whisper and breathe normally. © ChrisChrisW / Istock.com This is the first time that doctors have observed a patient with the implant long term recover functions such as breathing and speaking after the complete removal of the larynx. Thanks to an artificial voice box, implanted in 2015 at France's Strasbourg-Hautepierre university hospital, the 56-year-old Frenchman, who lives in Alsace, can now whisper in a comprehensible manner and breathe normally. The patient has also recovered his sense of smell, which was damaged by the removal of the larynx. Other than the vocal cords, the larynx features an upper valve, called the epiglottis, which closes when food passes down the throat to prevent it from entering the windpipe. The prosthetic larynx was developed by a French company called Protip Médical. It consists of a rigid titanium and silicone structure replacing the larynx and a removable titanium part that mimics the function of the epiglottis. The only problem that remains unresolved in the implant is the function of the epiglottis. As a result, the patient coughs from time to time when eating, as food accidentally enters the windpipe. However, the surgeons still consider the functioning implant [...]

Feds, cancer centers aim to boost HPV vaccinations

Source: www.dispatch.com Author: JoAnne Viviano Faced with getting her daughter the HPV vaccine, which helps protect against cervical and other cancers, Anaraquel Sanguinetti paused. The human papillomavirus is spread through sexual contact, and the Westerville mom didn’t want her now-18-year-old daughter to think she was promoting promiscuity. So Sanguinetti did some research. And she had a long talk with her daughter, and another with her doctor. In the end, daughter Celine got the vaccine last year. “We are discovering every day new reasons why people obtain cancer, so it’s just another added layer of protection for my daughter for her future, because you just never know,” Sanguetti said. “ I didn’t want to have a regret.” Sanguetti is in the minority. Though vaccinating against HPV is recommended by the Centers for Disease Control and Prevention, and countless cancer centers and health-care providers, most children in the United States have not been vaccinated against HPV. Calling that “a serious public health threat,” dozens of cancer centers released a joint statement on Wednesday urging more parents and pediatricians to get onboard. The statement endorses the CDC’s recent revisions to its HPV vaccine recommendations. Vaccinating, the statement says, could help prevent the nearly 40,000 cases of HPV-associated cancers diagnosed in the United States each year. “Get the HPV vaccine for your child so they don’t have to hear those words: ‘You have cancer,’ “ said Electra Paskett, co-leader of cancer control at Ohio State University’s Comprehensive Cancer Center, which is among the institutions [...]

Head and neck cancer art exhibition unveils hidden experience

Source: edmontonjournal.com Author: Madeleine Cummings Few words are as terrifying as these three: “You have cancer.” “When you’re told you have cancer, everything seems to fall apart,” said Ken Roth, who was diagnosed with squamous cell carcinoma on the base of his tongue four years ago. “Your head’s spinning, you don’t know what’s going on, you don’t know what the results are going to be,” he said. Brad Necyk, an artist and PhD student in psychiatry at the University of Alberta, tried to capture some of that disorientation in an installation that features a fragmented video of Roth’s face. His art is part of a new multimedia exhibition called “FLUX: Responding to Head and Neck Cancer,” which explores how head and neck cancer affects patients’ lives. (Ingrid Bachmann, Sean Caulfield, Jude Griebel, Jill Ho-You and Heather Huston also have works in the exhibit.) Roth had three-quarters of the base of his tongue removed and his illness led him to leave his job, but others have it a lot worse, he said. Patients with head and neck cancer often undergo lengthy (sometimes multiple) surgeries and they can have trouble speaking, swallowing and hearing. Some patients have to relearn how to speak, and then do it again after an additional surgery. These symptoms — many of which are visible — change how patients eat, communicate and behave in public. They can be devastating, and according to the Canadian Cancer Society, depression is common among the thousands of Canadians who have these kinds [...]

Immunotherapies Form New Frontier in Treating Head and Neck Cancers

Source: OncLive.com Date: January 2nd, 2017 In August 2016, the FDA approved pembrolizumab (Keytruda) for patients with platinum-refractory squamous cell carcinoma of the head and neck (SCCHN).1 Not only was it the first immunotherapy approved for head and neck cancer (HNC), but it marked the first new drug approval for HNC in the United States in 20 years. “Now we have an agent that really changes the paradigm—a new class of treatment—and we are seeing amazing benefit in some patients,” said Tanguy Seiwert, MD, during an OncLive Peer Exchange® panel held during the 2016 European Society for Medical Oncology (ESMO) Annual Meeting. Less than a month later, the menu of immunotherapy options expanded as the FDA approved nivolumab (Opdivo) for the treatment of patients with recurrent or metastatic SCCHN with disease progression on or after a platinum-based therapy. During the Peer Exchange, the panelists provided an overview of the immunotherapy terrain in HNC, a discussion that was filled with considerable hope and excitement. “When we try immunotherapies in the second-line setting, we see objective responses—sometimes deep, clinically meaningful, extremely durable responses—and we’re beginning to think that maybe, on some occasions, we may be able to cure patients with relapsed metastatic head and neck cancer,” said Kevin Harrington, MD, PhD. This is especially remarkable since such patients have generally had a survival of ≤1 year. The panelists concurred that the care of patients with HNC will evolve significantly over the next 5 to 10 years, as the tip of the immunotherapy [...]

Reducing Radiation Successfully Treats HPV-Positive Oropharynx Cancers and Minimizes Side Effects

Source: Yale Cancer Center, http://www.newswise.com/articles/reducing-radiation-successfully-treats-hpv-positive-oropharynx-cancers-and-minimizes-side-effects Released: 12/26/2016 Newswise — Human papillomavirus-positive oropharynx cancers (cancers of the tonsils and back of the throat) are on rise. After radiation treatment, patients often experience severe, lifelong swallowing, eating, and nutritional issues. However, new clinical trial research shows reducing radiation for some patients with HPV-associated oropharyngeal squamous cell carcinomas can maintain high cure rates while sparing some of these late toxicities. “We found there are some patients have very high cure rates with reduced doses of radiation,” said Barbara Burtness, MD, Professor of Medicine (Medical Oncology), Yale Cancer Center, Disease Research Team Leader for the Head and Neck Cancers Program at Smilow Cancer Hospital, and the chair of the ECOG-ACRIN head and neck committee. “Radiation dose reduction resulted in significantly improved swallowing and nutritional status,” she said. The study, published in the December 26 issue of the Journal of Clinical Oncology, showed that patients treated with reduced radiation had less difficulty swallowing solids (40 percent versus 89 percent of patients treated with standard doses of radiation) or impaired nutrition (10 percent versus 44 percent of patients treated with regular doses of radiation). “Today, many younger patients are presenting with HPV-associated squamous cell carcinoma of the oropharynx,” said Dr. Burtness. “And while traditional chemoradiation has demonstrated good tumor control and survival rates for patients, too often they encounter unpleasant outcomes that can include difficulty swallowing solid foods, impaired nutrition, aspiration and feeding tube dependence,” said Dr. Burtness. “Younger patients may have to deal with these [...]

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 [...]
