Oral cancer: How discovery devices assist screenings

Source: www.dentistryiq.com Author: Nick Efthimiadis, Vice President, Sales & Marketing, LED Dental Inc. As the intense media attention surrounding Michael Douglas’s illness clearly demonstrated, oral cancer is increasingly in the news these days. With the unfortunate growth in the number of relatively young people contracting the disease due to exposure to the sexually-transmitted human papilla virus — specifically, the HPV-16 strain — oral cancer will only become a bigger concern for both patients and dental practices over time. In fact, the Oral Cancer Foundation recently announced that HPV-16 has now replaced tobacco as the leading cause of this disease. Sadly, one North American dies every hour of every day from oral cancer, and many of those who survive the disease are forced to deal with lengthy, painful treatment and permanent disfigurement. The main problem is that oral cancer is typically discovered in late stages, when the five-year survival rate is only around 30%. The good news: when discovered early, the survival rate leaps to 80%-to-90%. The key to early discovery is the dental practice. Ideally, each and every practice should be conducting a two-step oral cancer screening on all adult patients as part of their annual or semi-annual hygiene checkup. The first step consists of a conventional “white light” exam comprising visual inspection and palpation. The second step consists of examination with an adjunctive screening device. Fortunately, the two steps should take no more than five minutes combined. For the past several years, the adjunctive device that has [...]

Alcohol linked to 10% of cancer cases, study finds

Source: www.irishtimes.com Author: Dr. Muiris Houston Reducing alcohol intake would reduce the number of cancer cases in the Republic, the Irish Cancer Society has said. It was responding to the results of a major European study, published online by the British Medical Journal, which found that up to one in 10 cancers in men and one in 33 in women could be caused by drinking. Researchers concluded that drinking above recommended alcohol limits was likely to be responsible for the majority of cancer cases linked to alcohol, although for some people even a small consumption may increase the risk. They analysed data from eight European countries, involving more than 360,000 men and women who were aged between 35 and 70 at the beginning of the study. The research is part of the European Prospective Investigation of Cancer, one of the largest ever studies into the links between diet and cancer. Some 17 per cent of bowel cancers in men were linked to drinking, as were 4 per cent of cases in women. And 5 per cent of cases of breast cancer in women were also linked to drinking, the study showed. Overall, more than 18 per cent of cancers in men were down to drinking more than 24g of alcohol a day. In women, 4 per cent of cancers were due to drinking more than 12g of alcohol daily. Naomi Allen, from Oxford University, one of the researchers, said: “This research supports existing evidence that alcohol causes cancer and that [...]

Oral tongue squamous cell carcinoma is on the rise in young caucasian females, age 18 to 44 years

Source: Journal of Clinical Oncology Abstract Purpose To evaluate the incidence of oral cavity squamous cell carcinoma (OCSCC) and oral tongue squamous cell carcinoma (OTSCC) in young white women, age 18 to 44 years. Patients and Methods We analyzed incidence and survival data from the Surveillance, Epidemiology and End Results (SEER) Program of the National Cancer Institute from 1975 to 2007 for OCSCC and OTSCC. Three cohorts were examined: all ages, age 18 to 44 years (ie, “young”), and age > 44 years. Individuals were stratified by sex and/or race. Percentage change (PC) and annual percentage change (APC) were calculated. Joinpoint regression analyses were performed to examine trend differences. Results Overall, incidence of OCSCC was decreasing for all ages. However, incidence was increasing for young white women (PC, 34.8; APC, 2.2; P < .05). Incidence of OTSCC was decreasing for all ages except in the age 18 to 44 years group (PC, 28.8; APC, 1.8; P < .05). Young white individuals had increasing incidence trends of OTSCC (white women: PC, 111.3; APC, 4; P < .05; young white men: PC, 43.7; APC, 1.6; P < .05). The APC of OTSCC was significantly greater in young white women compared with that in young white men (P = .007). Furthermore, incidence of SCC in all other subsites of the oral cavity was decreasing. Nonwhites had a decreasing incidence of OCSCC and OTSCC. Cause-specific survival was similar among whites age 18 to 44 and individuals older than age 44 years. Conclusion OTSCC [...]

Dental professionals join The Oral Cancer Foundation to raise awareness as HPV is now the primary cause of Oral Cancers in America

NEWPORT BEACH, Calif., April 4, 2011 /PRNewswire/ -- A serious change in the cause of oral cancer is taking place nationally, and its implications are impacting the American public in a manner that a decade ago no one would have predicted. For decades, oral cancer (also known as mouth cancer, tongue cancer, tonsil cancer, and throat cancer) has been a disease which most often occurred in older individuals, who during their lifetimes had been tobacco users. Most cases were ultimately the result of lifestyle choices. Today that paradigm has changed. A common, sexually transferred virus has replaced tobacco as the number one cause of oral cancers, Human Papilloma Virus number 16 (HPV16). This is one of the same viruses that are responsible for the majority of cervical cancers in women. This year alone, approximately 37,000 Americans will be newly diagnosed with oral cancer, and one person will die every hour of every day from this disease. HPV16, one of about 130 versions of the virus, is now the leading cause of oral cancer, and is found in about 60% of newly diagnosed patients. Dr. Maura Gillison from the James Cancer Center, a long time researcher of the relationship between HPV and oral cancers, recently reported these new findings at the American Academy for the Advancement of Science meeting. This change in etiology, which has accelerated its influence over the last two decades as tobacco use in the US simultaneously was declining, has also changed the demographics of who is getting [...]

Patient who loses jaw to oral cancer from smoking tells her story

Source: Los Angeles Times By: Milton D. Carrero, The Morning Call Look at Christine Brader's deep, amber eyes and you will see her beauty. Look beyond her contorted lips, and the jaw she lost as a three-time oral cancer survivor. Radiation took away her teeth, but she smiles. "I still feel like I've lost a great deal, she says, "but I'm still alive. And as long as I am alive, I am going to do what I can to help other people." Brader, 48, is sharing her face, her story and her time to tell the world about the dangers of smoking. The South Whitehall woman, who smoked about half-a-pack a day for 28 years, is featured in the national Truth campaign. Sponsored by the American Legacy Foundation, the series of ads present the unsweetened reality of those living with a serious illness caused by smoking. Brader's life is testament of resilience against oral cancer — a disease that, in five years, kills more than half of the 37,000 Americans diagnosed with it yearly, according to the Oral Cancer Foundation. "I still may not make it," she says, "and I don't have another chance in me. If I get it again, I'm done." Brader's life seemed idyllic until she discovered she had cancer. She had a stable job, a beautiful house in the woods and two teenage children who inspired her. But in 2007, she went to her family doctor, believing that she had a sinus infection. Her situation [...]

Longitudinal study of human papillomavirus persistence and cervical intraepithelial neoplasia grade 2/3: critical role of duration of infection

Journal of the National Cancer Institute, April 5, 2011. Authors: Ana Cecilia Rodríguez, Mark Schiffman, Rolando Herrero, Allan Hildesheim, Concepción Bratti, Mark E. Sherman, Diane Solomon, Diego Guillén, Mario Alfaro, Jorge Morales, Martha Hutchinson, Hormuzd Katki, Li Cheung, Sholom Wacholder, Robert D. Burk Background The natural history of human papillomavirus (HPV) infections in older women is critical for preventive strategies, including vaccination and screening intervals, but is poorly understood. In a 7-year population-based cohort study in Guanacaste, Costa Rica, we examined whether women’s age and the duration of carcinogenic HPV infections influenced subsequent persistence of infection and risk of cervical intraepithelial neoplasia grade 2 (CIN 2) or worse disease. Methods At enrollment, of the 9466 participants eligible for pelvic examination, 9175 were screened for cervical neoplasia using multiple methods; those with CIN 2 or worse disease were censored and treated. Participants at low risk of CIN 2 or worse (n = 6029) were rescreened at 5–7 years (passively followed), whereas higher-risk participants (n = 2115) and subsets of low-risk women (n = 540) and initially sexually inactive women (n = 410) were rescreened annually or semiannually (actively followed) for up to 7 years. HPV testing was done using a polymerase chain reaction–based method. We determined, by four age groups (18–25, 26–33, 34–41, and ≥42 years), the proportion of prevalent infections (found at baseline) and newly detected infections (first found during follow-up) that persisted at successive 1-year time points and calculated absolute risks of CIN 2 and CIN grade 3 (CIN [...]

HPV link comes as a shock to male cancer patients

By ANIKA CLARK Stanley Sikora of Fall River and Tom Souza of Swansea clearly remember when they started their battles with cancer — life-changing moments while raking leaves or shaving, when they touched their necks and felt a lump. It's a common experience thanks to a disease that, between the suffering of friends, families and ourselves, has become nearly universal. But then came news neither expected. Tumors from both men tested positive for human papillomavirus, an often sexually transmitted virus that is increasingly being linked to cancers of the head and neck. At Massachusetts General Hospital's Center for Head and Neck Cancers, "it's something that we see practically on a daily basis," said Dr. Lori Wirth, medical director for head and neck oncology, who said in an email that, although there are not-fully-understood co-factors, there's strong data that about 60-65 percent of all cancers of the oropharynx (the rear of the mouth, including the back of the throat, tonsils and the base of the tongue) are HPV-related. "Our awareness that HPV is associated with oropharynx cancers is something that has been emerging over the last 5-10 years," she said. "Ten years ago, we didn't even look for (it)." Upon learning of his HPV diagnosis, "I honestly felt creepy about myself," said Sikora, 59, albeit somewhat reassured when he found out how easily it's transmitted. "Already I was shocked that I got cancer. Now it's from HPV," he said. "So I'm thinking 'I can't be going around telling people I got [...]

We owe it to our sons to protect them against human papilloma virus – the new oral cancer peril

The seemingly unstoppable rise of throat and mouth cancers over the past two decades has left experts baffled and deeply concerned. These are truly horrible diseases. More than 15,000 new patients are diagnosed each year in Britain alone and almost 8,000 die from the most common type, cancer of the oesophagus. Two-thirds of sufferers are men. And those that survive are often left horrifically disfigured by aggressive radiotherapy and surgery. Most worryingly, numbers of new cases have doubled since 1989. We used to think most oral and throat cancers - which also include laryngeal (voice box), tracheal (windpipe) and oropharyngeal (soft-palate) tumours - were due to a lifetime of smoking and heavy alcohol consumption, and only really occurred in old age. But as health messages hit home, numbers of smokers and drinkers dropped, fewer older men and women developed these cancers and a new group of patients - middle-class, middle-aged men who drank moderately and had never smoked - emerged. This was a surprise. Small studies, in which tumours were analysed, indicated a new culprit: the human papilloma virus (HPV), the same virus that we knew was the cause of cervical cancer in women. For years there have been whisperings among oncologists that this could become one of the most significant cancer challenges of the 21st Century. And six weeks ago, evidence published by two American universities showed that these fears were becoming a reality. Researchers found that about half of the male population carried some form of HPV; that every year [...]

HPV type-specific prevalence using a urine assay in unvaccinated male and female 11- to 18-year olds in Scotland

Source: British Journal of Cancer Background: We conducted a baseline prevalence survey of unvaccinated 11- to 18-year olds to inform effectiveness studies for the new human papillomavirus (HPV) immunisation programme in Scotland. Methods: Participants were recruited from schools and colleges and invited to provide demographic data and an anonymous urine sample for type-specific HPV testing. Results: Among females aged 11–14 years, the weighted prevalence was 1.1% overall; 0.9% for high-risk types and no infections were associated with types 16 and 18. Among 15- to 18-year old females, the weighted prevalence was 15.2% overall; 12.6% for high-risk types and 6.5% for types 16 and 18. Among females aged 16–18 years, infection was more frequently associated with attending college and rural schools, and showed a trend towards increasing prevalence with increasing social deprivation (P=0.045). Among males aged 11–14 years, the weighted prevalence was 1.4% overall; 1.0% for high-risk types and 0.7% for types 16 and 18. Among 15- to 18-year old males, the weighted prevalence was 3.9% overall; 2.4% for high-risk types and 0.7% for types 16 and 18. Conclusions: Human Papillomavirus prevalence is low among 11- to 14-year olds, which includes the age group targeted for routine vaccination. The prevalence in males and correlation with deprivation require further investigation.

Study Finds Few Second Cancers Attributable to Radiotherapy

Elsevier Global Medical News Author: MA Moon It appears that only 8% of second solid cancers can be attributed to radiotherapy for a first cancer, according to a report published online March 30 in the Lancet. This figure varies somewhat according to the site of the first solid tumor, with the lowest attributable risk (4%) in cancers of the eye or orbit and the highest attributable risk (24%) in cancers of the testes. Given that only a small proportion of second cancers among adult survivors are likely to be related to radiotherapy, it follows that most second cancers arise from other causes, such as genetics or lifestyle factors, said Amy Berrington de Gonzalez, D.Phil., of the National Cancer Institute, and her associates. "These findings can be used by physicians and patients to put the risk of radiation-related cancer into perspective when compared with the probable benefits of treatment," the researchers noted. Many studies have shown an association between receiving radiotherapy for a first solid tumor and subsequently developing a second solid tumor. However, the proportion of second cancers that might be related to radiotherapy has not been investigated before, they said. Dr. Berrington de Gonzalez and her colleagues used data from the U.S. SEER (Surveillance, Epidemiology, and End Results) cancer registry to perform "a comprehensive and systematic analysis of all first solid cancer sites in adults that are routinely treated with radiotherapy." They included 647,672 patients who were 5-year cancer survivors and were aged 20 years and older when they were diagnosed with a first primary invasive solid cancer in 1973-2002. The participants were followed for 5-34 years (mean follow-up, [...]
