New therapy shortens treatment for HPV-related cancers of the tonsils, tongue

Source: medicalxpress.com Author: From Mayo Clinic News Network, Mayo Clinic News Network Patients with HPV-related oropharyngeal cancer who undergo surgery and are treated with chemotherapy, may be able to forgo significant radiation therapy without increasing the risk of their cancer spreading, according to the results of a clinical trial led by researchers at Mayo Clinic. "We found that decreasing the amount of radiation therapy after a minimally invasive robotic surgery improved the quality of life of patients with HPV-related oropharyngeal cancer while delivering excellent cure rates," says Dr. Eric Moore, a Mayo Clinic otolaryngologist. "In essence, we found exactly the right amount of treatment to deliver without over-treating these patients." Dr. Moore and his colleagues compared 79 patients treated at Mayo Clinic for HPV-related tonsil and tongue cancer with surgery and two weeks of radiation therapy to a group of 115 patients with the same cancer who were treated with surgery, and the standard six weeks of radiation therapy and chemotherapy. Dr. Moore and his colleagues found no decrease in survival or cancer recurrence in the group that received two weeks of radiation therapy, compared to the group that received six weeks of radiation therapy. He says that by decreasing the amount of radiation therapy after minimally invasive robotic surgery, physicians were able to improve the quality of life of patients and achieve excellent cure rates. "In essence, we found exactly the right amount of treatment to deliver without overtreating," says Dr. Moore. Dr. Moore says Mayo Clinic now offers [...]

Genetic changes in head and neck cancer, immunotherapy resistance identified

Source: MedicalXPress Date: April 26th, 2021 Author: University of San Diego-California A multi-institutional team of researchers has identified both the genetic abnormalities that drive pre-cancer cells into becoming an invasive type of head and neck cancer and patients who are least likely to respond to immunotherapy. "Through a series of surprises, we followed clues that focused more and more tightly on specific genetic imbalances and their role in the effects of specific immune components in tumor development," said co-principal investigator Webster Cavenee, Ph.D., Distinguished Professor Emeritus at University of California San Diego School of Medicine. "The genetic abnormalities we identified drive changes in the immune cell composition of the tumors that, in turn, dictates responsiveness to standard of care immune checkpoint inhibitors." Reporting in the April 26, 2021 online issue of the Proceedings of the National Academy of Sciences, researchers describe the role of somatic copy-number alterations—abnormalities that result in the loss or gain in a copy of a gene—and the loss of chromosome 9p in the development of human papillomavirus (HPV)-negative head and neck cancer. The loss of chromosome 9p and the deletion of JAK2 and PD-LI, two neighboring genes found on chromosome 9p, was associated with resistance to immune checkpoint inhibitors, a type of cancer immunotherapy that uses antibodies to make tumor cells visible to a patient's immune system. "Although programmed death-1 (PD-1) immune checkpoint inhibitors represent a major breakthrough in cancer treatment, only 15 percent of patients with HPV-negative head and neck cancer respond to treatment," said [...]

Dental Professionals Should Remember the HPV Vaccine Too

Source: Dentistry Today Date: April 13th, 2021 Author: Jo-Anne Jones We live in a viral world as we patiently await the end of the COVID-19 pandemic. Many people already have chosen to be vaccinated to protect themselves from getting the virus, or, at the very least, minimize its severity. The harsh nature of the pandemic has led to expediency in developing the vaccine, which has not been typical, historically speaking. While the COVID-19 vaccine took less than a year to develop, the mumps vaccine took four years. The polio vaccine took 13 years. The human papillomavirus (HPV), flu, and chicken pox vaccines took 17, 27, and 28 years, respectively. Looking back in the annals of history, we have the remarkable work of Edward Jenner to thank for his development of the first vaccine. His work involved deliberately infecting a human being with a mild dose of smallpox. His rigorous trials were controlled, repeatable, and documented in his 1798 publication, “An Inquiry Into the Causes and Effects of the Variolæ Vaccinæ.” Jenner devoted the remainder of his life advocating for the safe and effective administration of the vaccine. In 1972, routine smallpox vaccination ended in the United States, followed by the World Health Organization declaring the disease’s elimination in 1980. Another such vaccine victory is the polio vaccine, which was first available in the United States in 1955. Thanks to its widespread use, the United States has been polio-free since 1979. And while the United States government has said that dentists [...]

HPV vaccine leads to more than 80% drop in infections: What parents need to know

Source: Good Morning, America Date: April 2nd, 2021 Author: Kathleen Kindalen A new study has shown the effectiveness of the HPV vaccine, and found a dramatic decline in human papillomavirus infections in both vaccinated and unvaccinated teen girls and young women in the United States. "This study shows that the vaccine works very well against a common virus, HPV," Dr. Hannah Rosenblum, lead author of the study and medical epidemiologist at the Centers for Disease Control and Prevention (CDC), told "Good Morning America." "HPV can cause serious health problems later in life, including some cancers in both women and men," she said. "HPV vaccination is cancer prevention -- by vaccinating children at age 11 or 12, we can protect them from developing cancers later in life." HPV is the most common sexually transmitted infection in the United States and can cause health problems like genital warts in addition to cancer, which are most commonly cervical cancer in women and throat cancer in men, according to the CDC. The HPV vaccine was first authorized in the U.S. for females in 2006, and for males in 2011. There has since been a more than 80% decline in HPV infections nationally, according to the CDC study. The newly-released data from the CDC shows an 88% decrease in HPV infections among 14 to 19-year-old females and an 81% decrease among 20 to 24-year-old females. There has also been a drop in unvaccinated females, according to Rosenblum, who warned that does not mean people [...]

More parents balking at giving kids cancer-fighting HPV vaccine

Source: www.usnews.com Author: Steven Reinberg From 2012 to 2018, more doctors recommended their patients get vaccinated with the HPV vaccine -- from 27% to 49%. But at the same time, the number of parents who were reluctant to have their kids vaccinated increased from 50% to 64%, researchers found. "Overall, more U.S. teens are getting the HPV vaccine, and the nation is making progress towards reaching the HPV vaccination goals; however, if parental reluctance continues to grow, the current rate of our progress might plateau or possibly decline," said lead study author Kalyani Sonawane. She's an assistant professor in the department of management, policy and community health at the University of Texas Health Science Center in Houston. "In the long term, the lost opportunity to protect our teens from HPV might contribute to cases of HPV-associated cervical, oropharyngeal, penile, anal, vaginal and vulvar cancers in the future," Sonawane said. Parents' reluctance to have their kids vaccinated rose more for girls, from 54% to 68%, compared with 44% to 59% for boys, the researchers noted. The report was published online Feb. 9 in the journal Pediatrics. To increase the number of boys and girls who get vaccinated, doctors need to strongly recommend it, Sonawane said. "Further improvements in provider recommendations can be made, given that it is the most important factor for improving HPV vaccine uptake," she said. "Providers should be prepared to tackle hesitancy by conveying the importance of HPV vaccination to parents and debunking vaccine misinformation. Increasing vaccine confidence [...]

Timing and intensity of oral sex may affect risk of oropharyngeal cancer

Source: www.eurekalert.org Author: Research News Human papillomavirus (HPV) can infect the mouth and throat to cause cancers of the oropharynx. A new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society, has found that having more than 10 prior oral sex partners was associated with a 4.3-times greater likelihood of having HPV-related oropharyngeal cancer. The study also shows that having oral sex at a younger age and more partners in a shorter time period (oral sex intensity) were associated with higher likelihoods of having HPV-related cancer of the mouth and throat. Previous studies have shown that performing oral sex is a strong risk factor for HPV-related oropharyngeal cancer. To examine how behavior related to oral sex may affect risk, Virginia Drake, MD, of Johns Hopkins University, and her colleagues asked 163 individuals with and 345 without HPV-related oropharyngeal cancer to complete a behavioral survey. In addition to timing and intensity of oral sex, individuals who had older sexual partners when they were young, and those with partners who had extramarital sex were more likely to have HPV-related oropharyngeal cancer. "Our study builds on previous research to demonstrate that it is not only the number of oral sexual partners, but also other factors not previously appreciated that contribute to the risk of exposure to HPV orally and subsequent HPV-related oropharyngeal cancer," said Dr. Drake. "As the incidence of HPV-related oropharyngeal cancer continues to rise in the United States, our study offers a contemporary evaluation of risk [...]

Personalized vaccines: the new frontier in cancer treatment

Source: www.wildcat.arizona.edu Author: Udbhav Venkataraman Exciting results from a new clinical study showed that a personalized vaccine combined with an immunotherapy drug had a promising response rate in patients with advanced incurable head and neck cancer. Dr. Julie Bauman, chief of Hematology and Oncology at the University of Arizona College of Medicine — Tucson, led a phase one clinical trial with the pharmaceutical company, Moderna, to test the combined use of personalized vaccines created from tumor DNA with the immunotherapy drug pembrolizumab. Of the 10 patients involved in the study, five of the them responded to the treatment, meaning 30% of the cancer mass had decreased. Furthermore, two of the patients completely responded, meaning that cancer could not be detected. Molly Cassidy is one of those two patients. What was initially determined to be a stress-related ear-ache turned out to be an aggressive case of squamous cell carcinoma, a form of head and neck cancer. Head and neck cancers impact the linings of the mouth and throat. Risk factors for this disease include alcohol consumption, smoking and other environmental carcinogens that we are all exposed to. It can also be caused by human papillomavirus (HPV). Cassidy did not fit this profile at all. “I’m HPV-negative. I didn't drink. I didn't smoke. I’m a woman. I was the first person in my family to have cancer. I was 35 when I got my diagnosis,” Cassidy said. “I was also in really good health … To hear that I had cancer was [...]

Mouth cancer in the UK at record high

Source: www.hippocraticpost.com Author: staff New cases of mouth cancer in the UK have risen to a record high, according to the findings of a new report. New figures show there have been 8,722 new cases of mouth cancer in the UK last year. This is an increase of 58% compared to ten years ago and 97% compared to 20 years ago. Data released in a new report to coincide with November’s Mouth Cancer Action Month. Figures collected by the Oral Health Foundation show that 8,722 people in the UK were diagnosed with the disease last year, increasing by 97% since 2000. Mouth cancer cases in the UK have soared for the 11th year in a row and have more than doubled within the last generation. The findings are part of the charity’s new State of Mouth Cancer UK Report 2020/21 and have been released to coincide with November’s Mouth Cancer Action Month. Dr Nigel Carter OBE, Chief Executive of the Oral Health Foundation, believes with mouth cancer cases continuing to rise, more must be done to raise awareness of the disease. Dr Carter says: “While many cancers are seeing a reduction in the number of people affected, mouth cancer is one of very few that is sadly going the other way. Established risk factors like smoking and excessive alcohol have been joined by emerging causes like the human papillomavirus (HPV). This has changed the profile of the disease quite considerably over recent years and mouth cancer can now affect anybody. [...]

Smell of a person’s breath may help identify early cancers

Source: www.theweek.in Author: staff Cancer researchers from Flinders University have reported significant progress in developing a method to test exhaled breath profiles which accurately differentiate head and neck cancer from non-cancer patients. Previous studies elsewhere have indicated that the exhaled breath condensate can reveal gene mutations or DNA abnormalities in patients with lung cancer. The global quest to use a person's breath analysis for rapid, inexpensive and accurate early-stage testing for cancer and other diseases has taken a leap forward. The Australian researchers collected breath samples from 181 patients suspected of having early-stage head and neck squamous cell carcinoma (HNSCC) before any treatment began. "We sought to determine the diagnostic accuracy of breath analysis as a non-invasive test for detecting head and neck cancer, which in time may result in a simple method to improve treatment outcomes and patient morbidity," says lead researchers Dr Roger Yazbek and Associate Professor Eng Ooi. Worldwide, head and neck cancer accounts for 6 percent of all cancers, killing more than 300,000 people per year globally. Tobacco, alcohol and poor oral hygiene are known major risk factors for this cancer. A surge in human papilloma virus (HPV)-associated head and neck cancers is seeing these cancers affecting a much younger population, the researchers say. Current therapies are effective at treating early-stage disease, however late-stage presentations are common, and often associated with poor prognosis and high treatment-related morbidity. In the Australian study, a selected ion flow-tube mass spectrometer was used to analyse breath for volatile organic compounds. [...]

Most parents of unvaccinated teens have no intention of getting HPV vaccine for their kids, study finds

Source: www.newstribune.com Author: Kasra Zarei, The Philadelphia Inquirer The human papillomavirus (HPV) vaccine has been proven to prevent certain types of oral and genital cancers and other health problems. However, in a study published this week in Lancet Public Health, researchers found that more than half of the parents of adolescents who have not received the HPV vaccine had no intention to initiate the vaccine series for their children. Using data from a nationally representative survey of U.S. adolescents, the study authors estimated national-level and state-level parental intent to initiate and complete the HPV vaccine series for their kids. In states including Idaho, Montana, Nebraska, North Dakota, Oklahoma, and Utah, more than 65 percent of parents of unvaccinated adolescents had no intention to initiate the HPV vaccine series. According to the most recent data by the Centers for Disease Control and Prevention, Wyoming and Mississippi have the lowest HPV vaccine rates at roughly 50 percent. The new study found of parents of unvaccinated adolescents in these states, almost 62 percent and 57 percent, respectively, did not intend to initiate the HPV vaccine for them. Lack of parental intent to complete the vaccine series was lowest in the District of Columbia, at nearly 11 percent, and Rhode Island, at 20 percent. HPV vaccination is mandated in both regions. In Philadelphia, HPV vaccine coverage is among the highest in the country — roughly 71 percent in 2018, according to CDC data. Still, in Pennsylvania, between 60-65 percent of the parents of unvaccinated [...]
