Cancer research specialist believes uptake in HPV vaccine should be higher

Source: www.mayonews.ie Author: Anton McNulty Parents are potentially harming their children's health by not signing them up to receive the HPV vaccine, which protects against cancer in both males and females. That is the opinion of Martin Clynes, Emeritus Professor of Biotechnology in Dublin City University, who has spent his life researching cancer cells and how they develop in the body. The HPV vaccine is currently available free of charge to all second level students to protect against cervical cancer in women as well as other cancers. The free school-based vaccination programme started in 2010 but uptake of the vaccine slowed around 2016 when some parents established lobby groups because of concerns raised about the vaccine's safety. The current uptake is at 76 percent for the first dose and 65 percent for the second dose. Last year the scheme was extended to women under 25 years of age following a campaign from Bernie and Larry Brennan, parents of the late Laura Brennan who campaigned for higher uptake of the HPV vaccine before her death from cervical cancer in 2019, aged 26. Despite the European Medicines Agency (EMA) dismissing any long-term effects caused by the vaccine, Prof Clynes believes that the uptake is not as good as it should be. Speaking to The Mayo News ahead of a talk he gave on cancer as part of the Féile Chill Damhnait festival on Achill last Wednesday evening, Prof Clynes said parents should get their children to take the vaccine.

PET/CT follow-up may confer survival benefit in head and neck cancer

Source: www.cancertherapyadvisor.com Author: Andrea S. Blevins Primeau, PhD, MBA Annual follow-up with 18FDG-PET/CT can improve survival, as compared to conventional follow-up, in patients with head and neck cancer, according to study results published in JAMA Network Open. Researchers found that this survival benefit was driven by patients with advanced disease and those with oropharyngeal tumors. This study included 782 patients with head and neck squamous cell carcinoma (HNSCC) who were treated with curative intent during 2006-2019. Their median age was 61 (range, 32-95) years, and 82.1% of patients were men. The most common tumor site was the oropharynx (35.3%), followed by the larynx (24.8%), oral cavity (21.6%), and hypopharynx (15.5%). Most patients had stage IV disease (55.2%), followed by stage I (17.8%), stage III (15.5%), and stage II (11.3%). Exactly half of patients underwent surgery, and half received radiotherapy. The patients underwent 18FDG-PET/CT follow-up (n=497) or conventional follow-up (n=285). In both groups, follow-up included clinical examination every 2 months for the first year, every 3 months during year 2, and every 4 months during year 3, as well as imaging at 12 months, 24 months, and 36 months. Imaging consisted of chest CT in the conventional group and 18FDG-PET/CT in the other group. Over 3 years of follow-up, 111 relapses occurred, of which 62 (55.9%) were detected by 18FDG-PET/CT in patients who were asymptomatic. The subclinical recurrence detection rate was 12.4% with 18FDG-PET/CT. Of all subclinical recurrences, 18FDG-PET/CT revealed 58.1% at the 12-month follow-up, 30.6% at 24 months, and 11.3% [...]

Finding reconstructive solutions

Source: www.sydney.edu.au Author: George Dodd for Sydney Alumni Magazine They house the parts we need to see, hear, eat and breathe. Our heads and necks are machines for living but also subject to cancers that can destroy it all. New technology has changed all that. Nicola Salmond’s first thought was that the small ulcer inside her mouth was caused by her wisdom teeth. Her wisdom teeth were removed. The ulcer stayed. Then, a biopsy revealed that the ulcer was, in fact, a squamous cell carcinoma. Cancer. Specifically, a mouth cancer that is aggressive and can be life threatening. “People think they’re invincible, right?” says Salmond, a warm and straight-talking person, obviously still disquieted by the memory of the diagnosis. “I’ve never been fitter than I am now in my 40s. Yet there was this thing in my mouth. No symptoms at first, just this thing.” Professor Jonathan Clark in scrubs in front of a blue background, holding a 3D printed mouth piece Determined to stay in the lives of her three young daughters, Salmond joined in the search for a surgeon with the skills to help her. Professor Jonathan Clark (MBiostat ’12) came up early as one of the best in the field of head and neck surgery.

Promising drug that can kill all solid tumor cancers

Source: www.nextbigfuture.com Author: Brian Wang Above – The City of Hope-developed small molecule AOH1996 targets a cancerous variant of the protein PCNA. In its mutated form, PCNA is critical in DNA replication and repair of all expanding tumors. Here we see untreated cancer cells (left) and cancer cells treated with AOH1996 (right) undergoing programmed cell death (violet). (Photo credit: City of Hope) Researchers at City of Hope, one of the largest cancer research and treatment organizations in the United States, today published a new study explaining how they took a protein once thought to be too challenging for targeted therapy, proliferating cell nuclear antigen (PCNA), and developed a targeted chemotherapy that appears to annihilate all solid tumors in preclinical research. As the scientists continue to investigate the foundational mechanisms that make this cancer-stopping pill work in animal models, they note that there is an ongoing Phase 1 clinical trial testing the City of Hope-developed therapeutic in humans. Most targeted therapies focus on a single pathway, which enables wily cancer to mutate and eventually become resistant, said Linda Malkas, Ph.D., professor in City of Hope’s Department of Molecular Diagnostics and Experimental Therapeutics and the M.T. & B.A. Ahmadinia Professor in Molecular Oncology. However, the cancer-killing pill Malkas has been developing over the past two decades, AOH1996, targets a cancerous variant of PCNA, a protein that in its mutated form is critical in DNA replication and repair of all expanding tumors. “PCNA is like a major airline terminal hub containing [...]

Disparities in Oral Cancer: The need for early detection and treatment in the black community

Source: www.everydayhealth.com Author: Oladimeji Ewumi, Medically Reviewed by Walter Tsang, MD of American College of Lifestyle Medicine Oral cancer, also called mouth cancer, is a collective term for cancers that affect the mouth or oral cavity. This form of cancer can develop anywhere in the lips, gums, tongue, salivary glands, inner lining of the cheeks, roof of the mouth, or floor of the mouth. It also affects your oropharynx, which is the back part of your tongue, the roof of your mouth, tonsils, and the back of your throat. According to the American Cancer Society, there are about 54,540 new oral cavity and oropharyngeal cancer cases each year, which translates to 3 percent of all cancer diagnoses in the United States, per the National Institute of Dental and Craniofacial Research (NIDCR). Of these, Black Americans are more likely to receive a late diagnosis at an advanced stage of the disease, are less likely to get adequate treatment, and have worse overall survival rates than other racial-ethnic groups, according to a study published in Anticancer Research. The NIDCR reported that the five-year survival rate for oral cancer for Black people is 52 percent, compared with a 70-percent survival rate for white patients — even though there is a higher incidence of oral cancer in white Americans. These reflect a low awareness of oral cancer among Black Americans and hidden biases in the healthcare system. Reasons for Delayed Diagnosis in the Black Community A study published in OTO Open found that Black [...]

Meet the ‘Young Tongues’— including suburban mom, 48, part of shocking tongue cancer diagnosis boom

Source: www.survivornet.com Author: Danielle Cinone Understanding Head & Neck Cancers Tongue cancer is on the rise among young people in the United States, according to a recent Surveillance, Epidemiology, and End Results (SEER) Program analysis, and among those a diagnosed were a 48-year-old mom from Connecticut and a 22-year-old from England, both who are part of the “Young Tongues” group. Dr. Diana Kirke, an otolaryngologist at Mount Sinai Hospital who recently presented an analysis on “geographic trends in oral tongue squamous cell carcinoma among young individuals,” told TODAY.com, “since 2010, there seems to be a national shift to younger patients developing oral tongue squamous cell carcinoma. There is a very clear rise in patients that are non-smokers and non-drinkers.” Tongue cancer can be caused by a sexually-transmitted virus called HPV, and top experts suggest getting young adults vaccinated. “If I had any advice for you following a cancer diagnosis, it would be, first, to seek out multiple opinions as to the best care,” National Cancer Institute Chief of Surgery Steven Rosenberg told SurvivorNet in an earlier interview, “because finding a doctor who is up to the latest of information is important.” A recent Surveillance, Epidemiology, and End Results (SEER) Program analysis has revealed an oral tongue cancer boom is underway in the United States. Included in this increased incidence is Susan Smith, a 48-year-old mom from Fairfield, Connecticut, who is part of the “Young Tongues” group. Smith didn’t receive her tongue cancer diagnosis until she saw a fourth doctor who [...]

Focus on: Oral Pathology

Source: www.dentistrytoday.com Author: Ashley Clark, DDS Ashley Clark, DDS, discusses the specialized field of oral pathology—from what an oral pathologist does, to how to become one, and when to refer your patients to one. Q: First, what is an oral pathologist? A: An oral pathologist is a job description that is difficult to define, but we all have one thing in common: We are trained in microscopy to diagnose oral, skin, and jaw lesions. That is the most essential part of the profession that binds us all. We are also trained in clinical oral pathology—how to identify and manage oral diseases. Usually, oral pathologists work in academic institutions. This means we must do a combination of teaching, service, and research. After a decade in academia, I have chosen a transition to private practice, which is a bit rare for our profession. I spend my mornings driving around the city picking up biopsy specimens, then sign-in for cases that I receive from across the country. I also serve on a tumor board with my colleagues specializing in otolaryngology, radiology, speech therapy, prosthodontics, etc. Finally, I will provide about 70 continuing education courses/lectures this year (ranging from one to 16 hours long), which is more than normal. However, teaching is my favorite thing to do, so I tend to keep my schedule packed. Q: When should someone refer to an oral pathologist? A: If you are lucky enough to have an oral pathologist (or an oral medicine specialist) in your area, the [...]

HPV-related head and neck cancer may have two distinct subtypes

Source: www.curetoday.com Author: Brielle Benyon There may be two “intrinsically different subtypes” of HPV-positive head and neck cancer — one of which may be more likely to respond to radiation treatment, according to recent research published in the journal Proceedings of the National Academy of Sciences. “We're the first ones to describe these two subtypes,” study author, Dr. Wendell Yarbrough, Thomas J. Dark, distinguished professor of Otolaryngology/Head and Neck Surgery at the University of North Carolina Lineberger Cancer Center, said in a press release. “Using this research, we can firmly identify two groups of patients and are able to associate their tumor subtype with treatment outcomes.” The researchers discovered a difference in outcomes between patients with high and low NF-kB activity. Of note, NF-kB is a biomarker that activates the expression of pro-inflammatory genes and plays a role in inflammasome (response to infection- or stress-related stimuli) regulation, according to the National Institutes of Health. “Tumors with high NF-kB activity were more responsive to radiation therapy potentially contributing to improved patient survival,” Yarbrough said. “We know that there's something about activating the NF-kB pathway that makes the tumors more sensitive to radiation therapy, which could explain how and why those patients are surviving better.” These findings, according to the researchers, may help determine which patients should undergo these aggressive treatments, and which patients might fare better with a different approach. HPV-positive head and neck squamous cell carcinoma is typically treated with a combination of high-dose radiation and chemotherapy, though this regimen [...]

Sheffield team to develop patch that treats oral lichen planus

Source: www.theengineer.co.uk Author: Jason Ford A condition for which there is no cure could be treated more effectively following EPSRC-funded research being carried in the Department of Materials Science and Engineering at Sheffield University. With £471,789 in funding, the three-year project will develop a patch that can stay in the mouth to treat oral lichen planus (OLP), a chronic inflammatory mucocutaneous disease that presents itself as white, red and/or ulcerative lesions of the oral mucosa, which is the moist tissue that lines parts the body including the mouth. Drugs including steroids are available to treat OLP, but there is currently no effective way to administer them. Steroids also come with side effects and the relatively high doses needed to treat OLP can exacerbate them. Now, Professor Ipsita Roy and Dr David Alexander Gregory will develop a solution that delivers the drug locally and in a spatially selective manner. Professor Roy explained that this would facilitate a much lower dosage of therapeutic. A significant challenge, however, is to develop an adhesive that works in the wet environment of the mouth where tissue is highly mobile. To this end, the Sheffield team has obtained proof of concept data for a new highly adhesive polymer system (polyhydroxyalkanoates (PHAs)) that is produced by bacteria and is environmentally sustainable. This has been coupled with the polydopamine chemistry, used by mussels to attach to wet surfaces, to further enhance adhesiveness and be developed into an OLP patch. Work at Sheffield has shown that PHA is approximately [...]

Health effects of using snuffs that should not be ignored

Source: ng.opera.news Author: LoudestSilence86 In recent years, there has been a surge in the use of snuffs as an alternative to smoking cigarettes and chewing tobacco. Snuff is a powdered form of tobacco that is either inhaled through the nose or placed in the mouth. While some people believe that snuffs are a safer alternative to smoking or chewing tobacco, it is crucial to acknowledge that there are significant health effects associated with their use. According to webmd, This article aims to shed light on the health consequences of using snuffs that should not be ignored. Respiratory Health Risks One of the most concerning health effects of using snuffs is the impact on respiratory health. Snuffs are typically inhaled through the nose, causing numerous respiratory issues. The intimate contact of the tobacco powder with the nasal tissues can lead to chronic inflammation and irritation. Over time, this can cause nasal congestion, frequent nosebleeds, a decreased sense of smell, and even sinus infections. Furthermore, snuff contains high levels of nicotine, which is a highly addictive substance. Regular use of snuff can lead to the dependence on nicotine, making it difficult for users to quit. Oral Health Complications Snuffs that are placed in the mouth can have severe consequences on oral health. The tobacco powder in snuffs contains numerous harmful chemicals that can lead to dental problems. Continuous exposure to snuff can cause gum irritation, inflammation, and increased plaque buildup. These factors contribute to an increased risk of gum disease, tooth loss, [...]
