World-first saliva test detects hidden throat cancer

Source: www.miragenews.com Author: staff A simple saliva test developed by Queensland University of Technology (QUT) biomedical scientists has detected early throat cancer in a person who had no symptoms, and no clinical signs of cancer. QUT researchers Associate Professor Chamindie Punyadeera and Dr Kai Tang. A series of saliva HPV tests detected an asymptomatic throat cancer during a trial of a new saliva diagnostic Further validation studies are needed to confirm this finding It is a world-first discovery, previously there was no screening test for HPV-DNA oropharyngeal cancers The patient had surgery in which a 2mm cancer was removed and has had no recurrence of HPV-DNA in his saliva. In what is believed to be a world-first, the non-invasive test picked up HPV-DNA in a saliva sample from an infected healthy person. Persistent human papillomavirus (HPV) infection is now the leading cause of cancers in the oropharynx (tonsils and tongue base area of the throat). “The series of saliva tests raised the alert and detected an early cancer before the person had any symptoms,” said QUT Faculty of Health’s Associate Professor Chamindie Punyadeera, who, with Dr Kai Tang developed the test. “This enabled removal of the tonsil which had a 2mm cancer in it, by straightforward local surgery alone. “The incidence of high-risk human papillomavirus (HPV)-driven throat cancers is on the rise in developed countries and, unfortunately, it is often discovered only when it more advanced, with patients needing complicated and highly impactful treatment. “In the US, HPV-driven throat cancers [...]

Test that looks at your spit to tell if you have mouth or throat cancer caused by HPV ‘could save thousands of lives if rolled out for doctors to use’

Source: www.dailymail.co.uk Author: Connor Boyd, Health Reporter A saliva test that diagnoses mouth and throat cancer caused by HPV could save thousands of lives each year, a study suggests. Scientists at Duke University in North Carolina discovered the test was 80 per cent accurate at spotting the killer diseases. Doctors say it is able to detect the cancers early on, giving patients much higher hopes of surviving their battle. Before it can be used in hospitals around the world, further trials will be needed to confirm the technology works. But the researchers are hopeful, claiming the cheaper test - which gives results in as little as 10 minutes - has significant 'potential'. Rates of oral cancers are soaring in the Western world, with the number of patients diagnosed in the UK having doubled in a generation. US doctors have also seen a similar spike in the diseases, which can be caused by human papilloma virus (HPV). The infection – spread through oral sex, as well as anal and vaginal intercourse – is thought to cause around 70 per cent of all cases. Other risk factors include drinking excessive amounts of alcohol over long periods of time and smoking cigarettes. Professor Tony Jun Huang, study co-author, said there are around 115,000 cases of oropharyngeal cancers each year across the world. He said it is 'one of the fastest-rising cancers in Western countries due to increasing HPV-related incidence, especially in younger patients'. Orophayngeal cancer starts in the oropharynx, the back of the [...]

The surge in throat cancer, especially in men

Source: newswise.com Author: UC Davis Comprehensive Cancer Center Humanpapilloma virus (HPV) is now the leading cause of certain types of throat cancer. Dr. Michael Moore, director of head and neck surgery at UC Davis and an HPV-related cancer expert, answers some tough questions about the trend and what can be done about it. Q: What is HPV and how is it related to head and neck cancers? A: There are about 150 different types of HPV, but HPV 16 is the one that most frequently causes cancers that affect the tissue in the oropharynx, which includes back of the throat, soft palate, tonsils and the back or base of the tongue. You can get non-cancerous lesions from other types of HPV that look like warts in the nose, mouth or throat, called papillomas. Some can develop in childhood just from exposure early in life. Some develop later in life and only occasionally turn into cancer. Q: How do you get HPV? A: HPV can spread from mother to her baby around the time of delivery. It also spreads through unprotected vaginal, anal or oral sex, and even open-mouth kissing. Some people have been found to be infected without an obvious cause. Q: How does HPV cause cancer? A: Most people who are infected clear the virus on their own. In a small group of people it hangs around and causes a persistent infection. Around 1% of US adults have a persistent HPV 16 infection, and in a small subset of [...]

The scary reason doctors say kids need HPV vaccinations

Source: www.washingtonpost.com Author: Sarah Vander Schaaff When actor Michael Douglas told a reporter that his throat cancer was caused by HPV contracted through oral sex, two themes emerged that had nothing to do with celebrity gossip. The first was incredulity — since when was oral sex related to throat cancer? Even the reporter thought he had misheard. The second was embarrassment. This was too much information, not only about sexual behavior but also about one’s partners. Douglas apologized, and maybe the world was not ready to hear the greater truth behind what he was suggesting. That was four years ago. Today, there is no doubt in the medical community that the increase in HPV-related cancers such as the one Douglas described — which he later explained was found at the base of his tongue — is caused by sexual practices, in his case cunnilingus. And there is an urgency to better treat and prevent what is becoming the one type of oral cancer whose numbers are climbing, especially among men in the prime of their lives who have decades to live with the consequences of their cancer treatment. The number of people diagnosed with HPV-related oropharyngeal cancer, tumors found in the middle of the pharynx or throat including the back of the tongue, soft palate, sides of throat and tonsils — is relatively small — about 12,638 men and 3,100 women in the United States each year, according to the Centers for Disease Control and Prevention. But these numbers are [...]

Merck KGaA, Pfizer and Transgene team up on cancer vaccine

Source: www.biopharmadive.com Author: Joe Cantlupe Dive Brief: Transgene announced Tuesday it is teaming up with Merck KGaA of Darmstadt, Germany, and Pfizer to evaluate the possibilities of the combination of its human papillomavirus (HPV)-positive head and neck cancer vaccine TG40001 with big pharma’s avalumab in a Phase 1/2 study. The incidence of HPV-related head and neck cancers has increased significantly, with one variation, HPV-16 accounting for 90% of all HPV-related head and neck cancers. HPV-16 is a subset of head and neck squamous cell carcinoma (HNSCC), a group of cancers that can affect the mouth and throat. Global spending on head and neck cancer indications amounted to $1 billion in 2010, according to the companies’ recent estimates. Current treatments for the disease include surgical resection with radiotherapy or chemo-radiotherapy; the companies say they are exploring better options for advanced and metastatic HPV and HNSCC. Dive Insight: The current deal between the big pharma partners and Transgene highlights the industry's efforts to create combination therapies to treat cancer. Virtually every company in the space has embraced the idea that using multiple modes of attack could be the only way to eventually find cures for the many forms of cancer; companies have been teaming up in hopes of finding that crucial pairing. In previous clinical trials, TG4001 has demonstrated promising activity in terms of HPV viral clearance and was well tolerated, according to Transgene. TG4001 is one of the few drugs targeting HPV-associated cancers that can be combined with an immune checkpoint [...]

HPV is changing the face of head and neck cancers

Source: www.healio.comAuthor: Christine Cona A drastic increase in the number of HPV-associated oropharynx cancers, particularly those of the tonsil and base of tongue, has captured the attention of head and neck oncologists worldwide. In February, at the Multidisciplinary Head and Neck Cancer Symposium in Chandler, Ariz., Maura Gillison, MD, PhD, professor and Jeg Coughlin Chair of Cancer Research at The Ohio State University in Columbus, presented data that showed that the proportion of all head and neck squamous cell cancers that were of the oropharynx — which are most commonly HPV-positive cancers — increased from 18% in 1973 to 32% in 2005. Maura Gillison, MD, PhD, Jeg Coughlin Chair of Cancer Research at The Ohio State University, said screening for HPV in the head and neck is years behind cervical screening for HPV. In addition, studies from the United States, Europe, Denmark and Australia indicate that HPV-positive patients have a more than twofold increased cancer survival than HPV-negative patients, according to Gillison. With the rising incidence of HPV-related oropharynx cancers, it will soon be the predominant type of cancer in the oral or head and neck region, according to Andy Trotti, MD, director of radiation oncology clinical research, H. Lee Moffitt Cancer Center & Research Institute, in Tampa, Fla. “We should be focusing on HPV-related oropharyngeal cancer because it will dominate the field of head and neck cancers for many years,” he said during an interview with HemOnc Today. “It is certainly an important population for which to continue to [...]

Nonsurgical surveillance safe, cost-effective for head, neck cancer

Source: www.healio.com Author: Mehanna H, et al. Patients with head and neck cancer who underwent PET/CT–guided surveillance achieved similar survival outcomes as those who underwent planned neck dissections, according to the results of a prospective, randomized controlled trial. However, surveillance led to fewer surgical operations and complications and appeared more cost-effective than neck dissection, results showed. Patients with head and neck cancer frequently undergo invasive surgery following treatment to remove remaining cancer cells, according to study background. “After treatment, remaining cancer cells play something akin to hide and seek,” Hisham Mehanna, MBChB, PhD, FRCS, chair of head and neck surgery at University of Birmingham and director of the Institute of Head and Neck Studies and Education, said in a press release. “Our study shows that we can hunt them down, find them and remove them effectively.” Mehanna and colleagues sought to define the role of image-guided surveillance compared with planned neck dissection for the management of patients with advanced, nodal head and neck squamous cell carcinoma previously treated with primary chemoradiotherapy. The analysis included data from 564 patients (mean age, 58 years; 82% men) who researchers randomly assigned to PET/CT–guided surveillance (n = 282) performed 12 weeks after the end of treatment or planned neck dissection (n = 282). Oropharyngeal cancer served as the most common cancer subtype (84%). Seventy-five percent of patients had HPV-16–positive disease. Patients assigned surveillance only underwent neck dissection if their PET/CT scans showed incomplete or equivocal response to chemoradiotherapy. The trial was designed to assess [...]

Expanded age indication cleared for Gardasil 9 in males

Source: www.FormularyJournal.ModernMedicine.comAuthor: Erin Bastick FDA approved an expanded age indication for Human Papillomavirus 9-valent Vaccine, Recombinant (Gardasil 9, Merck) in males. Seven HPV types in Gardasil 9 (HPV 16, 18, 31, 33, 45, 52, and 58) cause approximately 90% to 95% of HPV-related anal cancers, 90% of cervical cancers, and 80% of high-grade cervical lesions worldwide.These 7 types also cause the majority of HPV-related vulvar and vaginal cancers. Gardasil 9 includes the greatest number of HPV (Human Papillomavirus) types of any available HPV vaccine. Gardasil 9 was previously approved for use in girls and young women aged 9 to 26 years for the prevention of cervical, vulvar, vaginal, and anal cancers caused by HPV 16, 18, 31, 33, 45, 52, and 58, precancerous or dysplastic lesions caused by HPV 6, 11, 16, 18, 31, 22, 45, 52, and 58, and genital warts caused by HPV types 6 and 11. As for use in male patients, the vaccine was previously approved for use in boys aged 9 to 15 years for the prevention of anal cancer caused by HPV types 16, 18, 31, 33, 45, 52, and 58, precancerous or dysplastic lesions caused by HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58. With the newest approval, Gardasil 9 is now also indicated for use in males aged 16 to 26 years for the prevention of these diseases. According to the CDC, HPV vaccination rates are unacceptably low compared to rates for other adolescent vaccines, and vaccination coverage in [...]

HPV DNA detected in mouthwash predicts oral cancer recurrence

Source: www.onclive.com Author: Kelly Johnson The presence of HPV16 DNA is common at diagnosis of HPV-related oropharyngeal carcinoma (HPV-OPC) but rare after treatment. HPV-OPC has a favorable prognosis; however, 10% to 25% of patients experience disease progression, usually within 2 years of treatment. Patients who have HPV 16 DNA in their saliva following treatment of their oropharyngeal cancer are more likely to have their cancer recur, and a prospective cohort study published in JAMA Oncology has shown that a simple mouth rinse can be used to detect it. Gypsyamber D’Souza Gypsyamber D’Souza, PhD, Johns Hopkins Bloomberg School of Public Health, and fellow researchers monitored 124 patients with newly diagnosed oropharyngeal cancer from 2009 through 2013. They collected oral rinse and gargle samples using 10 mL of mouthwash at the time of diagnosis as well as after treatment 9, 12, 18, and 24 months later. HPV16 DNA was detected in 67 out of 124 of the participants testing positive. Of the 67 patients who had HPV16 DNA in their saliva at the time of diagnosis, five patients (7%) were found to still have traces of HPV16 in their oral rinses following treatment. All five patients developed a local recurrence of oropharyngeal cancer, three of whom died from the disease. “It’s a very small number so we have to be somewhat cautious,” said D’Souza, an associate professor in the Department of Epidemiology at the Bloomberg School and a member of the Sidney Kimmel Comprehensive Cancer Center, in a statement. However, [...]

AstraZenica, Inovio strike deal to find HPV cancer vaccine

Source: www.philly.comAuthor: David Sell Local drugmakers - big and small - struck a deal to try to develop a vaccine to prevent a form of cervical, head and neck cancer. MedImmune, which is the biologics and research division with AstraZeneca, said Monday it will collaborate with Inovio Pharmaceuticals to develop an early stage cancer vaccine designed to treat human pappilomavirus. AstraZeneca will pay Inovio $27.5 million upfront. If the compound reaches development and commercial milestones, Inovio could get up to $700 million, along with "double-digit tiered royalties" on product sales. However, sales are a long way off because the compound is only in phase I and phase II of what is normally a three-phase clinical trial process. AstraZeneca is moving its headquarters from London to Cambridge in the United Kingdom, and has operations in Wilmington and Fort Washington. The MedImmune division is headquartered in Gaithersburg, Md. Inovio is based in Blue Bell and its basic scientific premise is to use DNA to develop vaccines. unlike most current vaccines. The companies have worked together before. The compound at the heart of the latest deal is called INO-3112. The early clinical trials are examining cervical and head and neck camcers and the compound tries to generate "killer T-cell responses that are able to destroy HPV 16- and 18- driven tumors. These HPV types are responsible for more than 70 per cent of cervical pre-cancers and cancers, " according to the statement. The full statement from AstraZeneca is here. *This news story was [...]
