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 [...]

HPV symptoms and health consequences

Source: www.kristv.com Author: Roland Rodriguez No one dreams of walking into his or her doctor’s office and hearing the words "you have been diagnosed with human papillomavirus, or HPV." Unfortunately, this scenario is all too real. HPV is the most common sexually-transmitted infection (STI) in the United States. In fact, it's so common that nearly all sexually active men and women get it at some point in their lives. There are over 100 different kinds of HPV but only some of them can cause serious health problems like genital warts or cancer of the cervix, vagina, vulva or anus. Testing positive for HPV does not automatically mean you will get cancer. Some studies estimate that 50 percent of those infected with HPV will clear the virus within eight months— and 90 percent will be cured within two years. It's only when your immune system isn’t able to fight off the infection that some strains of HPV can persist and possibly lead to cancer. The number of human papilloma virus (HPV)-associated cancers in the United States has increased by 17 percent, to nearly 39,000 cases a year, according to a report released from the Centers for Disease Control and Prevention. While men cannot get HPV-linked cervical cancers, they are particularly vulnerable to HPV-related cancers of the mouth, tongue and throat, called oropharyngeal cancers. According to the new CDC report, the rates of mouth and throat cancers are more than four times higher among males than females. In the past, people always [...]

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 [...]

Why men need to start caring about HPV

Source: www.refinery29.com Author: Sarah Jacoby The human papillomavirus (HPV) is one of very few STIs that we have a vaccine for. And — bonus! — that vaccine prevents cancer. But a report from the U.S. Centers for Disease Control and Prevention (CDC) released last month indicated that although we've made some improvements in the vaccination rates, they still aren't where we want them — especially for boys. This is despite the fact that pretty much everyone who's sexually active will get the virus at some point and men are at risk for their own unique set of HPV-related health consequences. Let's start with the basics: "HPV is a virus that’s sexually transmitted, but it’s incredibly common," explains Kathleen Schmeler, MD, of the University of Texas MD Anderson Cancer Center. Up to 80% of people get it at some point in their lives, she says, which is why some doctors refer to it as the "common cold" of STIs. For most people, the virus goes away on its own, without causing symptoms or needing treatment. Some people develop genital warts that can be treated with medication. But in some rare instances, the virus can go on to cause more serious health issues — including some types of cancer. "The problem is we don't know who’s going to clear it and who won’t," Dr. Schmeler says. Most notably, HPV is known to cause cervical cancer. In fact, nearly all cases of cervical cancer are attributed to HPV. In 2013, the most recent [...]

Chronic sinusitis linked to head and neck cancers in elderly

Source: www.cancernetwork.com Author: Anna Azvolinsky Chronic sinusitis is associated with three rare types of head and neck cancer, including nasopharyngeal cancer, human papillomavirus (HPV)-related oropharyngeal cancer, and nasal cavity and paranasal sinus cancers, according to a new study published in JAMA Otolaryngology–Head & Neck Surgery. Chronic sinusitis is local inflammation caused by either a virus or bacteria that lasts for longer than 12 weeks. Either the chronic inflammation from the sinusitis, the immunodeficiency that can accompany chronic sinusitis, or both may contribute to the development of these head and neck cancers. The effect is modest, however, wrote the study authors. “There are currently no general US guidelines for head and neck cancer screening, but given the low absolute risk, our findings do not support a need for head and neck cancer screening in individuals with chronic sinusitis,” wrote study authors Daniel C. Beachler, PhD, MHS, and Eric A. Engels, MD, MPH, of the infections and immunoepidemiology branch of the National Cancer Institute in Bethesda, Maryland. The absolute risk of these cancer types was low. At 8 years after a chronic sinusitis diagnosis, they had a cumulative incidence of less than 0.07%. The authors conducted a case-cohort study using the Surveillance, Epidemiology, and End Results (SEER)–Medicare database to assess this link among elderly individuals in the United States. The authors included 483,546 Medicare beneficiaries and an additional 826,436 individuals from the database who developed cancer, including 21,716 individuals who developed head and neck cancer. The mean age of individuals in the [...]

Impact of cancer screening in California over past 15 years

Source: www.sciencedaily.com Author: University of California - Davis Health System A new report from the UC Davis Institute for Population Health Improvement (IPHI) shows the impact of cancer screening over the past 15 years, identifying areas where increased screening and other cancer-control efforts would save lives and significantly benefit population health. The CalCARES report uses heat maps to show areas with higher proportions of particular cancers diagnosed at a late stage, pointing to a need for increased screening. The CalCARES report uses heat maps to show areas with higher proportions of particular cancers diagnosed at a late stage, pointing to a need for increased screening. "We have effective screening tests for several cancers, which allow physicians and other health-care providers to identify the disease at an earlier stage -- often before symptoms surface -- when treatment is more likely to result in a cure," said senior author of the report and IPHI Director Kenneth W. Kizer. "However, too many Californians are not getting screened and, as a result, many persons are not being diagnosed until their cancers have progressed to an advanced stage. "With cancer now surpassing heart disease as the leading cause of death in California and 22 other states, we need to increase cancer screening efforts to save lives," he said. IPHI's California Cancer Reporting and Epidemiologic Surveillance (CalCARES) Program works in partnership with the California Department of Public Health to manage the day-to-day operations of the California Cancer Registry (CCR), the state mandated population-based cancer surveillance system.

Google and UCLH to develop AI to improve cancer therapies

Source: www.phgfoundation.org Author: Julian Harris Google’s Artificial Intelligence research group announced a new partnership with University College London Hospitals, applying machine learning to radiotherapy treatment for head and neck cancer. The new partnership is the third since the launch of DeepMind’s health division in February 2016. The partnership aims to assist clinicians in the segmentation process – designating which areas of the body to target with radiotherapy – which in the case of head and neck cancer is highly time consuming, taking around four hours. The agreement will give DeepMind access to the anonymised scans of around 700 patients, as well as the expertise of UCLH’s world leading team at their specialised head and neck cancer centre. Google DeepMind hopes to utilise machine learning to make the planning of radiotherapy treatment more efficient and reduce the duration of the segmentation process. Ultimately , clinicians will still be responsible for deciding on treatment plans, but the reduced workload will free up their time to focus on patient care. If successful, the team hope that they will be able to adapt their segmentation algorithm to other parts of the body and other cancers which can also be treated with radiotherapy. Machine learning continues to be a promising new area of health technology, with the potential to provide novel solutions to a range of problems in healthcare. In the UCLH press release, the Co-Founder of DeepMind, Mustafa Suleyman said that "this real-world application of artificial intelligence (AI) technology is exactly why we set [...]

Expert Asserts Pembrolizumab to Play Important Role in Head and Neck Cancer Treatment

Source: www.targetedonc.com Author: Laura Panjwani The FDA approval of pembrolizumab (Keytruda) as a treatment for patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) in August 2016 was extremely significant for this patient population, which previously had limited options following progression on a platinum-based chemotherapy. The approval was based on the phase Ib KEYNOTE-012 study, which demonstrated that pembrolizumab had an overall response rate (ORR) of 18% and a stable disease rate of 17% in patients with recurrent/metastatic HNSCC. Several other studies are further evaluating the immunotherapy agent in HNSCC.Preliminary results of the phase II KEYNOTE-055 study—which included 92 evaluable patients who received pembrolizumab after failing platinum and cetuximab therapies—were presented at the 2016 ASCO Annual Meeting. In an interview with Targeted Oncology, lead study author Joshua M. Bauml, MD, an assistant professor of Medicine, Hospital of the University of Pennsylvania and the Veteran's Administration Medical Center, discusses the impact of pembrolizumab’s success in HNSCC, the results of the KEYNOTE-055 study, and what he sees on the horizon for the PD-1 inhibitor in this field. TARGETED ONCOLOGY: What role do you envision pembrolizumab having in this patient population? Baumi: It is going to play a critical role in head and neck cancer. The other agents that are available have limited efficacy, and are associated with significant toxicities. This is a clear improvement for our patient population with limited options. TARGETED ONCOLOGY: What were the key takeaways from KEYNOTE-055? Baumi: Patients with recurrent/metastatic head and neck cancer that [...]

New method of cancer immunotherapy developed

Source: www.nextbigfuture.com Author: staff A team of Stanford ChEM-H scientists has discovered a novel form of cancer immunotherapy, which works by removing certain sugars from the surface of cancer cells and making those cells visible to the immune system. Scientists have long known that if certain sugars are present on a tumor, it is less likely to respond well to therapies. But nobody knew what that halo of sugars was doing, in part because such a small number of labs study the glycocalyx. Evidence had been mounting within those few labs that do study the glycocalyx, including Bertozzi’s, that a subset of sugars called sialic acids act as a signal for the innate immune system to ignore the otherwise suspicious-looking tumor. Eliminate those sugars, and maybe innate immune cells would be more likely to recognize and attack the cancer cells, Bertozzi thought. And essentially that’s exactly what happened. Current immunotherapies on the market work by blocking one of the inhibitory signals that are recognized by the adaptive immune system. Block those and the balance tilts in such a way that the immune system will attack the now recognizable cancer. Bertozzi’s approach provides a second way of tiling the balance in favor of attack, this time for the innate immune system. She said this study shows just one example of how it could work, but her sugar-removing lawnmower could be used on a wide variety of cell types, not just those expressing HER2, and on different types of sugars.

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.
