The rise of HPV-related cancers in men

Source: www.tmc.edu Author: Alexandra Becker Scott Courville admired his full beard and round belly in the mirror: He was ready for the upcoming holiday season. It was November 2015 and Courville, who plays Santa Claus in Lafayette, Louisiana, was too excited about his favorite time of year to worry much about the pain developing in his jaw. By February, though, the ache had worsened and was accompanied by new symptoms: white spots on his right tonsil, difficulty swallowing and lumps in his throat. He finally made his way to a walk-in clinic where he was diagnosed with tonsillitis and prescribed antibiotics. “They sent me home and said, ‘In two weeks everything should clear up,’” Courville recalled. But his symptoms only worsened. Courville made an appointment with a local ear, nose and throat (ENT) specialist who also diagnosed Courville with tonsillitis. The doctor prescribed more antibiotics and steroids, but two weeks later there were no improvements. Courville was referred to a dentist—“In case they see something we don’t”—but that, too, was a dead end. Courville’s dentist insisted he return to his ENT, where he ultimately had a CT scan that revealed a mass in his throat. That was June 6, 2016. Two days later, Courville underwent a biopsy. When he awoke from the surgery, his doctor was standing over him. Courville always gets choked up retelling this part of his story. “The hardest part for me is always remembering when the doctor said, ‘I’m sorry, but you’ve got cancer.’” Courville was [...]

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.

Shedding light on oral cancer

Source: www.laboratorytalk.com Author: staff A team of Indian cancer researchers led by Dr Narayanan Subhash has developed a simple, non-invasive spectral imaging system that holds the possibility of rapid, inexpensive mass screening. Even in the hands of non-clinical staff, it is capable of real-time discrimination of healthy oral tissue from pre-malignant and malignant tissues with accuracy comparable to the gold standard histopathology of a biopsy sample. The core of the novel Diffuse Reflectance Imaging System (DRIS) is an Andor Luca-R EMCCD camera, which captures monochrome images of the patient’s mouth at 545 and 575 nm. Andor’s SOLIS software computes a ratio image (R545/R575) of the area under investigation and generates a Pseudo Colour Map (PCM) where blue designates healthy tissue, red denotes dysplastic/pre-malignant tissue and yellow identifies malignant tissue. This allows rapid visual differentiation of oral lesions and identification of regions with pre-malignant characteristics. “Since mortality from oral cancer is particularly high, early detection, diagnosis and treatment is vital in increasing the survival rate of those with the disease,” says Dr Subhash. “Our imaging method has the great advantage of non-invasively scanning entire lesions and their surrounding areas and automatically categorising these oral lesions into normal/clinically healthy, pre-malignant, and malignant tissue in real-time. “It also delineates the boundaries of neoplastic changes and locates sites with the most malignant potential for biopsy, thereby avoiding unnecessary repeated biopsies and delay in diagnosis. What’s more, imaging the entire region may also help the surgeons to identify the margins of the lesion that cannot be [...]

What the ‘rinse-and-spit’ oral cancer test could mean for dental professionals and their patients

Source: www.dentistryiq.com Author: Vicki Cheeseman, Associate Editor A new oral cancer “rinse-and-spit” test for the early detection of tumors could mean great things for dental professionals and their patients when the test becomes available for use in dental practices nationwide possibly as early as late 2014 or into 2015. The test, developed at the University of Miami Miller School of Medicine and exclusively licensed to Vigilant Biosciences, Inc., will be available as a low-cost, point-of-care screening test for the early detection of oral cancer, and is envisioned as a kit with a special oral rinse and test strip. The test strip detects proteins that are markers of oral cancer and are captured by the rinse. The markers may be present before a lesion is easily visible. Early detection tests are critical because the majority of patients present in late stage when cure rates reach only 40%. I asked Dr. Franzmann to explain how the test strip works. “The beauty of the test strip approach is that it is so simple for the patient and health-care professional to use. The technology behind the test strips has been around for many years and is used for many medical applications. The key is to know what to test for. Through our research, we discovered certain proteins, or markers, are present in the saliva in the early stages of squamous cell carcinoma, the most common head and neck cancer.” How early can tumors be detected with the test strip? Dr. Franzmann said, “The tumors [...]

April: Oral Cancer Awareness Month

Source: Aspen Dental April is Oral Cancer Awareness Month. According to Brian Hill, founder and executive director of the Oral Cancer Foundation, as many as 40,000 people in the United States will be told they have oral or pharyngeal cancer in 2012. Some of them may be sitting in your dental chair today. With one person dying of oral cancer every hour of every day, and more than 50% of those diagnosed not living more than 5 years, this is a reminder to screen every patient yourself, and encourage your dental hygiene staff to do the same. The Statistics About 100 people are diagnosed with oral cancer every day in the United States. Few people are aware that the death rate for oral cancer is higher than for many other types of cancers, which is because oral cancer often is not discovered until it has reached later stages. This is particularly true for human papilloma virus number 16 (HPV16)-related oral cancer, which occurs most frequently in the posterior areas of the mouth—at the base of the tongue, around the tonsils, and in the oropharynx—where it’s harder to spot without a very thorough exam. To further complicate things, HPV16-related cancer does not always present the tell-tale physical characteristics, including lesions, that are easily distinguished from healthy oral tissues. This is not good news, because HPV16 has reached epidemic levels in the United States: of the 37,000 incidences of oral cancer, about 20,000 (up to 60%) can be linked to HPV, according [...]

Studies underscore genetic complexity of head and neck squamous cell cancers

Source: Dentistry IQ By Maria Perno Goldie, RDH, MS While we should be screening patients for oral and pharyngeal cancer daily, April has been designated as the month when we highlight this disease, and increase awareness about its prevention and treatment. Powerful new technologies that pinpoint the connections between human genes and diseases have clarified the background of cancer, singling out changes in tumor DNA that force the development of certain types of malignancies. Several major biomedical centers have collaborated to study head and neck squamous cell cancer. Their large-scale analysis has revealed a surprising new set of mutations involved in this disease. The studies underscored the genetic complexity of head and neck squamous cell cancers. Two independent, multi-institution research teams identified a large number of genetic defects associated with head and neck squamous cell carcinoma (HNSCC), the most common form of head and neck cancer. The researchers sequenced the entire protein-coding regions, or exomes, of the DNA in dozens of patient tissue samples.(1,2) Tobacco use, excessive alcohol consumption, and human papillomavirus (HPV) infection are known risk factors for HNSCC, including cancers occuring in the mouth and throat. The 5-year survival rate for many types of HNSCC has improved little over the past 40 years. According to the authors, the degree of differentiation, or tumor cell grade, has never consistently been shown to be a clinical prognostic factor in HNSCC. They said it was surprising to find mutations in a series of genes that appear to contribute to differentiation. Both [...]

Fluorescent spray that can catch throat cancer early offers hope to 8,000 Britons diagnosed each year

Source: Dailymail.co.uk A throat spray has been developed to spot cancer of the oesophagus at an early stage. The disease, which killed Morse star John Thaw, is one of the most deadly cancers because it is often missed or wrongly diagnosed until too late. Current methods used to detect it can be inaccurate, so many patients are given unnecessary invasive treatment including removal of their oesophagus, the ‘food pipe’ that connects the throat to the stomach. Early detection key: If caught early, the cancerous cells can be zapped with an electric current which kills them without surgery. Now scientists have developed a fluorescent dye spray which sticks to healthy cells in the oesophagus but cannot attach itself to cancer cells or those in the early stages of turning cancerous. This gives a clear signpost to where the disease is developing. If caught at this stage, the cancer cells can be ‘zapped’ with an electric current which kills them without surgery. The treatment offers hope to more than 8,000 Britons a year who are diagnosed with oesophageal cancer. One of the patients in the study had their entire oesophagus removed because a small pre-cancerous area had been identified – which using the dye was found to have been very small and could have been treated without surgery. Deadly: Oesophageal cancer is one of the most fatal because it is often missed or wrongly diagnosed until it is too late. Two patients whose cancer had not shown up using the current imaging [...]

Oral Cancer Foundation Sponsors 13th Annual Oral Cancer Awareness Month in April 2012

Source: Dentistry IQ Organization encouraging dental professionals to offer free screenings to the public Did you know that the fastest growing segment of the oral cancer community is young, healthy non-smokers? It's shocking but true. Exposure to the HPV-16 virus, the most common sexually transmitted infection, is now the leading cause of oral cancers in the U.S. There is little that can be done to stop this virus from spreading. Our only hope to save lives is through increased professional involvement and public awareness to generate early discovery of the disease process. To that end, the Oral Cancer Foundation (OCF) is encouraging the dental community to get involved in Oral Cancer Awareness Month this April 2012 by offering free oral cancer screenings to the public in a national effort to raise awareness of this silent killer. Oral cancer has existed outside the consciousness of much of the public, which is one reason 37,000 Americans will be newly diagnosed this year alone. That is about 100 new people a day. That lack of awareness has contributed to this cancer not being discovered until very late in its development. By implementing a public awareness campaign, OCF wants to educate the public about the risk factors, early signs and symptoms of the disease, as well as the need for all adults to undergo an annual oral cancer screening. In the early stages of oral cancer's development, it is often is painless, and physical signs may not be obvious to an individual. This makes [...]

Biosciences aims to lower oral cancer mortality with simple screening test

Source: www.proactiveinvestors.com Author: Amanda Brandon Vigilant Biosciences is a privately held medical technology company based in Norcross, Georgia focused on improving healthcare products to improve patient care. Their most recent research efforts center on early oral cancer detection. In the United States, approximately 37,000 people will be diagnosed with oral cancer this year and its most common risk factor is exposure to the human papillomavirus (HPV). Nearly 40 percent of oral cancer patients will die within five years of diagnosis. The high mortality rate for oral cancer is due to late discovery of the malignancy. In its early stages, the disease can either present no symptoms or the symptoms are often mistaken for other conditions. VigilantBIO is currently trialing an easy-to-use, low-cost and noninvasive oral cancer screening product which tests the saliva (a very desirable biofluid). The patient and practitioners (e.g. dentists, hygienists, periodontists) benefit from the simplicity of the test – no venipuncture means higher test participation and no specialized staff is required to perform the test. In the oral clinical setting, this is ideal because it does not interfere with chair turnover ratio. In addition, test results can be delivered at the point of care. When oral cancer is detected early, patients experience an 80-90 percent survival rate. Combined with the lowered treatment cost (an estimated 36 percent) and easy-to-implement product for oral care practitioners, the early detection product appears to be a winner for all involved. With two clinical trials in process at the University of Miami, [...]

New Evaluation for HPV16 Related Cancers Using “Pap-Test Equivalent”

Source: Cancer Prevention Research Abstract Human papillomavirus (HPV) is responsible for the rising incidence of oropharyngeal squamous cell cancers (OSCC) in the United States, and yet, no screening strategies have been evaluated. Secondary prevention by means of HPV detection and cervical cytology has led to a decline in cervical cancer incidence in the United States. Here, we explored an analogous strategy by evaluating associations between HPV16 infection, cytopathology, and histopathology in two populations at elevated risk for OSCCs. In the first, a cross-sectional study population (PAP1), cytology specimens were collected by means of brush biopsy from patients presenting with oropharyngeal abnormalities. In the second (PAP2), a nested case–control study, bilateral tonsillar cytology samples were collected at 12-month intervals from HIV-infected individuals. The presence of cytopathologic abnormality in HPV16-positive tonsil brush biopsies (cases) was compared with HPV16-negative samples (controls) matched on age and gender. HPV16 was detected in samples by consensus primer PCR and/or type-specific PCR. Univariate logistic regression was used to evaluate associations. In PAP1, HPV16 alone (OR: 6.1, 95% CI: 1.6–22.7) or in combination with abnormal cytology (OR: 20, 95% CI: 4.2–95.4) was associated with OSCC. In PAP2, 4.7% (72 of 1,524) of tonsillar cytology specimens from HIV-infected individuals without oropharyngeal abnormalities were HPV16 positive. Tonsillar HPV16 infection was not associated with atypical squamous cells of unknown significance (ASCUS), the only cytologic abnormality identified. Therefore, HPV16 was associated with OSCCs among individuals with accessible oropharyngeal lesions but not with cytologic evidence of dysplasia among high-risk individuals without such lesions.
