Management strategies for oral potentially malignant disorders

Source: www.medscape.com
Author: Joel M. Laudenbach, DMD

Oral potentially malignant disorders (OPMDs) include oral leukoplakia (OL), oral erythroplakia, oral submucous fibrosis, oral lichen planus, proliferative verrucous leukoplakia, and actinic keratosis. Once an OPMD has been clinically diagnosed, execution of management strategy is critical. When formulating the strategy, healthcare providers should consider histopathology, lesion characteristics (ie, surface texture, unifocal, multifocal), lesion location in the mouth (ie, tongue, floor of mouth), patient risk factor assessment, and a detailed medical/cancer history.

In this newly published article, Nadeau and Kerr[1] detail various parameters surrounding evaluation and management of OPMDs. The authors make it clear that OPMDs are challenging, each with their own nuances regarding risk for malignant transformation. For example, when OL is unifocal, nonhomogeneous, nodular, or verrucous, there is a much higher chance of the OL becoming dysplastic (12.63-fold) or demonstrating a focus of carcinoma (8.9-fold) when compared with homogeneous types of OLs.[1]

Provider knowledge of these variables is critical when counseling patients about their diagnosis and management options and when selecting interventions along with follow-up care. Although progression to malignancy is difficult to predict with OPMDs, clinicians can account for multiple risk factors such as smoking/alcohol status, high-risk location in the oral cavity, and size of lesion (>200 mm2) to help formulate a tailored management plan for each patient. Consultation with an oral pathologist to discuss the histologic appearance in the context of specific patient history and lesion characteristics can provide additional perspective and/or recommendations.

Modifiable oral cavity cancer risks related to tobacco and heavy alcohol use should be communicated to patients with OPMDs so that they are able to make changes that may lead to regression/disappearance of certain lesions such as OL. Providers confronted with patients who use tobacco and/or heavy alcohol can integrate recommendations for cessation of tobacco[2] and alcohol[3] because they are both established, independent, causative agents for oral cavity cancer and OPMDs.

Available treatment strategies for OPMDs include surgical removal/ablation, photodynamic therapy, and surveillance. The authors make a clear point with supportive studies that traditional surgical excision of dysplastic OPMDs may decrease malignant transformation (MT) risk, yet it does not fully eliminate that risk and, in some instances, has not changed the MT risk when compared with surveillance alone. Appropriate surgical margin identification for OPMDs is clinically challenging. The authors note that smaller excisional margin sizes (1-2 mm) without marginal histologic assessment are common surgical management goals for OPMDs.[1]

Nadeau and Kerr carefully outline updated considerations for all OPMDs. Healthcare providers involved in screening, diagnosing, referring, and/or managing patients with OPMDs should be well versed in standards of care, including baseline biopsy goals, tobacco/alcohol cessation, currently available interventions, and surveillance care.

Clinicians should also develop a local team of practitioners who are experts in diagnosis and management of OPMDs to help patients obtain the best opportunity for positive outcomes. I encourage readers with interest to retrieve and review the full article by Nadeau and Kerr as a strategy to update your knowledge base and to continue to improve overall morbidity, mortality, and survival rates related to OPMDs.

Experts reveal why men are four times more likely to get cancer from oral sex than women

Source: www.thesun.co.uk
Author: Sofia Petkar

Men are four times more likely than women to be diagnosed with oral cancer, as studies suggest a lower immune system could be behind this. Research has found men who perform oral sex on their female partners have a higher than average chance of developing an oral cancer triggered by the human papilloma virus (HPV).

While sexual norms and fewer inhibitions have played a role in this alarming trend, scientists now say the male immune system is the real problem. Research has found that compared with women, men are more likely to be infected with HPV and its “high-risk” cancerous strains. Men are also less able to get rid of the infection through the body’s natural defences, harbouring the virus for longer periods of time.

Ashish A. Deshmukh, a University of Florida HPV researcher, said: “There is good evidence that men acquire oral infections more readily than women, even if they have similar sex practices.

“And more than the acquisition, it’s the persistence of the virus.

“The clearance rate is not that fast in men.”

Traditionally, smoking and heavy alcohol usage were seen as the big risk factors for oral cancer. However, studies have shown that non-HPV tumours linked to these bad habits has declined significantly in recent years. In stark contrast, HPV-related tumours have increased more than 300 per cent over the last 20 years, with the virus now found in 70 per cent of all new oral cancers.

In 2013, Michael Douglas hit the headlines when he blamed his throat cancer on oral sex. The 72-year-old actor said he believed his cancer was triggered by the HPV virus, which he says he contracted after performing oral sex.

While many ridiculed his theory, experts say there is growing evidence to support his claims. The human papillomavirus (HPV) is a very common sexually transmitted disease which affects at least half of people who are sexually active. The STD is the most widespread worldwide and four out of five of the population will contract some form of the virus at least once in their life.

The types of HPV found in the mouth are almost entirely sexually transmitted, so oral sex is seen as the primary route of contracting them. In most cases, the body’s immune system will fight off the virus and there won’t be any need for further tests, in fact, some people may not even know they contracted it at all.

The HPV infection affects the skin and mucosa (any moist membrane, such as the lining of the mouth and throat, the cervix and the anus).

Dentists have warned that dating apps such as Tinder are putting more people at risk of catching HPV passed on by oral sex. The British Dental Association said: “Data used to model sexual behaviour are out of date, and factors such as the recent introduction of dating apps may have led to significant changes in behaviour over the last few years, which have not been taken into account.”

Non-smokers with oral precancerous lesions at increased risk of cancer

Source: www.eurekalert.org
Author: press release

Precancerous lesions in the mouths of non-smokers are more likely to progress to cancer than those in smokers, new research from the University of British Columbia has found.

Although tobacco use is still one of the strongest risk factors associated with mouth cancers, UBC dentistry PhD candidate Leigha Rock found that oral precancerous lesions in non-smokers are more than twice as likely to progress to cancer. Furthermore, lesions in non-smokers progressed to cancer faster than smoking-associated lesions. The study was published this week in Oral Oncology.

“This is the first published study where the main focus was to examine the difference in risk of progression to oral cancer between non-smokers and smokers with oral precancerous lesions,” said Rock, lead author of the study. “While other studies have also reported a higher rate of transformation among non-smokers, we looked at multiple risk factors including genetic markers.”

Rock and colleagues looked at case history of 445 patients with oral epithelial dysplasia (OED), a type of precancerous oral lesion, enrolled in the B.C. Oral Cancer Prediction Longitudinal study. One-third of the patients were non-smokers.

“As smoking rates decline, we are seeing an increase in the proportion of these types of lesions in non-smokers,” said Rock.

Among the scientists’ findings were that lesions on the floor of the mouth in non-smokers were 38 times more likely to progress to cancer than in smokers. The study is also the first to report on quicker progression to cancer in non-smokers: both three-year and five-year rates of progression were seven per cent and 6.5 per cent higher than smokers, respectively.

The researchers suggest that the marked difference in outcomes is due to a difference in the root causes of the lesions. In smokers, the OED is likely the result of environmental factors, whereas in non-smokers, genetic susceptibility or mutations are likely to blame.

“Our findings show that molecular genomic markers can identify high risk lesions, regardless of risky habits like smoking, and should be an important consideration in patient management,” said Rock.

The study’s results stress the importance of taking oral lesions seriously, especially when they occur in non-smokers: “If you see a lesion in a smoker, be worried. If you see a lesion in a non-smoker, be very worried. Don’t assume it can’t be cancer because they’re a non-smoker; our research indicates non-smokers may be at higher risk.”

HPV is causing an oral cancer epidemic in men by outwitting natural defenses

Source: www.philly.com
Author: Marie McCullough, staff writer

Five years ago, when actor Michael Douglas candidly revealed that his throat cancer was linked to having oral sex, two things happened.

He made headlines that mortified his family. And he helped publicize the fact that a pervasive, sexually transmitted virus called HPV was unleashing an epidemic of oral cancer among men.

Since then, scientists have made headway in figuring out why HPV, the human papillomavirus, has this glaring gender bias. Men are four times more likely than women to be diagnosed with oral cancer, a hard-to-detect, hard-to-treat disease that has overtaken cervical cancer as the most common HPV-related malignancy in the United States.

To be sure, changes in sexual norms over the last few generations have played a role in this alarming trend. But research increasingly shows the real problem is something men have practically no control over: their immune response.

Compared with women, men are more likely to get infected with HPV — including “high-risk” cancer-causing strains. They also are less able to wipe out infection on their own, and more likely to get reinfected. The reasons are unclear.

“There is good evidence that men acquire oral infections more readily than women, even if they have similar sex practices,” said Ashish A. Deshmukh, a University of Florida HPV researcher. “And more than the acquisition, it’s the persistence of the virus. The clearance rate is not that fast in men.”

Michael Becker of Yardley has stepped up as the face of this immunological inequity. The 49-year-old former biotech executive is health-conscious, clean-living, happily married for 26 years – and battling terminal oropharyngeal cancer, the medical term for malignancies in parts of the mouth and throat.

He’s also battling the misconceptions and ignorance that keep too many parents from protecting their pubescent children — especially boys — against HPV-driven cancers. Two shots. That’s all it takes for the leading vaccine, Gardasil, to prevent most cervical cancers, less common genital malignancies, and the disease that is killing Becker.

“I can’t tell you how many emails I got from parents after the CBS segment,” he said, referring to a national television interview last month. “They said, ‘What do you mean this vaccine is for boys?’ and ‘What do you mean oral cancer incidence has eclipsed cervical cancer?’ ”

An inescapable virus
HPV is a family of more than 100 virus types that can live in the flat, thin cells on the surface of the skin, cervix, vagina, anus, vulva, penis, mouth, and throat. The virus is spread through contact with infected skin, mucous membranes, and bodily fluids. Some types can be passed during intercourse or — as Douglas pointed out — oral sex. While virtually all sexually active people will get infected at some point, the virus is usually wiped out by the immune system without so much as a symptom.

But not always.

In the cervix, persistent infection with high-risk HPV types can lead to precancerous changes that, left alone, slowly turn malignant. Fortunately, the Pap smear enables the detection and removal of abnormal cells before cancer develops. What’s more, age-related changes in cervical cells reduce the risk that HPV will take hold there as women get older.

No such screening test exists for oropharyngeal sites – the tongue, soft palate, tonsils, the throat behind the nasal cavity – and symptoms usually don’t appear until cancer is advanced. Becker, for example, had metastatic disease by the time he noticed a lump under his jaw line in late 2015.

Traditionally, smoking and heavy alcohol use are the big risk factors for oral cancer, but the non-HPV tumors linked to these bad habits have been declining in recent years. HPV-related tumors, in contrast, have increased more than 300 percent over the last 20 years. The virus is now found in 70 percent of all new oral cancers.

About 13,200 new HPV oral cancers are diagnosed in U.S. men each year, compared with 3,200 in women, according to federal data. Treatment — surgery, chemotherapy, radiation — can have disfiguring, disabling side effects. About half of late-stage patients die within five years.

Natural defenses go awry
Oral HPV infection rates are skewed by gender, just like the resulting cancers. The latest national estimates of this disparity, published in October, come from Deshmukh and his University of Florida colleagues. They used a federal health survey that collected DNA specimens to estimate that 7.3 percent of men and 1.4 percent of women have oral infections with high-risk HPV types. That translates to 7 million men and 1.4 million women.

The chance of oral infection increases for women as well as men who have simultaneous genital HPV infections or a history of many sex partners, but male infection rates still far surpass female rates.

Patti Gravitt, an HPV researcher at George Washington University, believes these estimates are a bit oversimplified because women counted as uninfected may actually have undetectably low virus levels, or HPV may be hiding in a dormant state in their cells.

Still, Gravitt said the study is in line with others that suggest “men are more susceptible to HPV viral infection than women.”

In women, an HPV infection usually sets off the body’s defense mechanisms. The immune system makes antibodies that kill off the invader, then immune cells remain on guard, ready to attack if the virus reappears.

But in men, something goes awry. The HIM study — for HPV in Men — documented this by collecting genital, anal, and oral samples from 4,100 unvaccinated men in Florida, Mexico and Brazil between 2005 and 2009. The samples were tested for the presence of two high-risk HPV types and two that cause genital warts.

Among 384 men who developed infections during a 24-month period, only 8 percent produced antibodies. But this response rate varied depending on the site of infection; none of the small number of orally infected men produced antibodies.

Rather than putting the immune system on guard and protecting men from the virus, infection sharply increased the chance of getting infected again with the exact same HPV type. And many men who got reinfected were celibate at the time.

How could this be? Anna R. Giuliano, the researcher at the Moffitt Cancer Center in Tampa, Fla., who led the HIM study, said recurring infections may be due to reactivation of dormant virus, or to auto-inoculation – the man spreads infection from one part of his body to another. Or to something else entirely.

While the scientific understanding of this puzzle is evolving, one implication is clear. “HPV vaccination is the only reliable method to ensure immune protection against new HPV infections and subsequent disease in males,” Giuliano and her co-authors declared in a recent paper.

Becker hammers that message – when he is not being hammered by chemotherapy – using his self-published memoir and his blog. This week’s blog gave a shout-out to Sunday’s first-ever International HPV Awareness Day, declared by Giuliano and other members of the International Papillomavirus Society.

Becker realizes that the novelty of the vaccine, the complexity of HPV, and its link to sex are obstacles to immunization. But he focuses on the life-saving aspect.

“Parents are being asked to vaccinate their 11-year-old child and they can’t imagine 30 or 40 years down the line, it will prevent cancer,” Becker said. “If you don’t know it’s connected to six cancers, you’re not going to care. So it really should be cast as an anti-cancer vaccine.”

HHC study supports web-based care plans for head, neck cancer patients

Source: www.hartfordbusiness.com
Author: John Stearns

A joint study by the Hartford HealthCare (HHC) Cancer Institute and the Memorial Sloan Kettering (MSK) Cancer Center has demonstrated benefits of a web-based care plan for patients with head and neck cancer as a tool to better cope with side effects of treatment.

A web-based tool to help patients with head and neck cancer better deal with effects of their cancer treatment has proved beneficial to patients and doctors, according to a HHC doctor involved in developing the tool and studying its effectiveness.

“The compelling reason to do this work is because head and neck cancer has changed,” said Dr. Andrew Salner, medical director of the Hartford HealthCare Cancer Institute at Hartford Hospital, HHC’s lead doctor on the joint study with MSK.

Head and neck cancer, once mostly associated with heavy drinkers and smokers who had other chronic diseases, is showing up more in younger and healthier patients, he said. That’s because of the prevalence of human papillomavirus (HPV), now the leading cause of the cancers that often target the tonsils and back of the tongue.

HPV is the most commonly sexually transmitted infection in the U.S. HPV is equally divided among males and females, the latter who’ve been getting vaccinated against HPV to prevent cervical cancer, but oral cancers are happening more prevalently and are appearing in males and females, Salner said. As such, boys and girls are now recommended for the vaccine before they become sexually active to hopefully prevent future disease, he said.

Immunization rates were 38 percent for boys and 50 percent for girls in 2016, Salner said.

Most people with HPV will not develop cancer, according to HHC, but for those who do, treatment outcomes are good, but the effects of head and neck cancer treatment can cause difficulty with taste and swallowing, dental problems, jawbone injury, underactive thyroid and other issues, Salner said.

The study of 43 head and neck cancer patients in Hartford and New York tracked the benefit of a web-based care plan tailored to their specific cancer, treatment and side effects. Historically, so-called survivorship care plans were fairly generic in addressing issues patients might or might not encounter, Salner said.

“This study was unique because it personalized the side effects for the tumor site and the treatment for each patient,” Salner said. It offers specific effects to watch for, some of which may not show up for years after treatment, ways to help prevent problems, cope with treatment side effects and timelines for follow-up medical screenings.

“The patients really appreciated all components of the care plan,” which also included a 60- to 90-minute meeting to review with medical staff.

HHC and MSK are talking with the National Cancer Institute to do a much wider study of the care plan, Salner said. He also wants to examine how to scale up the plan for larger populations and integrate it into patients’ medical records.

Salner and Dr. David Pfister, chief of head and neck oncology services at the MSK Cancer Center, will discuss the study and link between HPV and head and neck cancer in a talk this afternoon, from 4 to 5, at the Hartford Hospital Wellness Center at Blue Back Square, West Hartford.

E-cigarette Vapor Filled With Dangerous Toxins Like Lead, Study Finds

Source: www.newsweek.com
Author: Melissa Matthews

Electronic cigarettes may have been deemed safer than traditional smoking by the American Cancer Society, but that doesn’t make it a risk-free habit. Past research has found that oils used to vape contain toxins, and a new study shows that the latest e-cigarette devices might leak dangerous amounts of metal, including lead, which could have serious health risks.

In a study published in the February 2017 issue of Environmental Research, public health expert Ana María Rule of Johns Hopkins University found that liquids used in the first generation of e-cigarettes could be potentially toxic and carcinogenic. However, things have changed in just one year as companies constantly offer new, more sophisticated devices. Plus, Rule was often met with questions about the safety of inhaled aerosol.

“A lot of people were asking, ‘You found these metals in the liquid, but what does this mean?’ Are they getting into the vapor that I’m inhaling?’” Rule explained to Newsweek.

So, the team began a new project studying the latest devices, called Mods, as well as the aerosol inhaled by smokers.

For this study, 56 daily e-cigarette smokers lent their devices to Rule’s lab, where scientists tested the vaping liquid, liquid inside the e-cigarette tanks, and the aerosol. They looked for 15 different metals including lead, chromium, nickel and manganese, which are the most dangerous, according to Rule.

Some of the refilling dispensers did contain small amounts of metal. However, liquids in the e-cigarette tanks and aerosols contained higher levels. Rule believes the heating coils found in the tanks could somehow be transferring metal into the aerosol. This is alarming as aerosol is inhaled by users.

The data showed that nearly 50 percent of aerosol samples contained lead in quantities above the Ambient Air Quality Standards set by the Environmental Protection Agency. In addition, the concentrations of nickel, chromium and manganese found in nearly half of the aerosol samples exceeded the limits. Every e-cigarette in the study was different, so the amounts varied per model. This variety, explained Rule, is one of the study’s strengths.

“Every person that came into our study brought in their own device,” she said. “We think it’s representative of what people are vaping in the country.”

Arsenic also was found in some of the e-liquid samples, both in the chamber and refills, as well as some vapor samples.

Now that exposure has been established, the next steps are to determine if, and how, it impacts the body. Rule hopes this study, and corresponding research, will push the Food and Drug Administration to begin regulating e-cigarette pens. She believes quality control and newer, safer devices are issues that need to be addressed.

“Maybe there’s another way to heat or isolate the liquid from the heating element,” she said. Although she doesn’t believe vaping is safe, Rule asserts there needs to be better devices for those who insist on the habit. “There’s got to be a safer way to do it,” she said.

Should kids be required to get the HPV vaccine?

Author: Bruce Y. Lee

If a bill recently introduced in Florida passes, the human papillomavirus (HPV) vaccine would be mandatory for adolescents attending public school in the state.

Florida isn’t kidding about low human papillomavirus (HPV) vaccination rates. If you are a kid enrolled in a Florida public school, come July 1, 2018, you may be required to get the HPV vaccine. That is if you are old enough and if a bill now being debated in the Florida state legislature ends up passing.

If it gets through, Senate Bill 1558 would then become known as the “Women’s Cancer Prevention Act”, which is a much easier name to remember and also reflects some major benefits of the HPV vaccine. As the National Cancer Institute explains, HPV vaccine can help prevent not only cervical cancer but also many vaginal and vulvar cancers. In fact, two types of HPV (16 and 18) cause around 70% of cervical cancers. But just because you don’t have a vagina, cervix, and vulva doesn’t mean that you are in the clear. HPV is responsible for about 95% of anal cancers, 70% of oropharyngeal (the middle part of the throat) cancers, and 35% of penile cancers. Thus, the “Women’s Cancer Prevention Act” is really a “Cancer Prevention Act.”

Regardless, Florida State Senator José Javier Rodríguez (D-Miami) filed this bill on January 4 in an effort to boost Florida’s not so great HPV vaccination rates. According to the just-released Blue Cross Blue Shield Association (BCBSA) Health of America Report, only 29.0% of adolescents in Florida got the first dose of the HPV vaccine and only 7.3% got all doses in the series as of 2016. Those numbers are lower than the national average (34.4% got the first dose) but not the worst in the country.

New Jersey was the worst (not in general as a state but in terms of HPV vaccination rates). Based on the BCBSA report, as of 2016, only 20.6% of adolescents in New Jersey had gotten the HPV vaccine by age 13 and only 3.4% had completed the series. The Health of America report was the result of an analysis of medical claims data from 2010 through 2016 of over 1.3 million BCBSA commercially-insured adolescents across the country. The analysis considered vaccination to be on time if performed between the adolescent’s 10th and 13th birthdays, corresponding with the Centers for Disease Control and Prevention (CDC) recommendations of 11 to 12 year olds getting the vaccine.

Of course, the analysis did not include all adolescents in America. As BCBSA Chief Medical Officer Trent Haywood, MD, JD, explained, “the analysis represented the commercial population and didn’t include Medicaid populations. Also, to be included in the analysis, an adolescent had to be continuously enrolled with BCBS.” But studying such a large population is a pretty good shot at trying to figure what’s going on with shots and adolescents nationwide.

The report also showed that girls were better than boys (again, not in general, but in terms of HPV vaccination rates). In 2016, 37% of girls had received the first dose of the HPV vaccines by age 13 compared to 32%.

The best state of the bunch? Rhode Island with 57% of adolescents having received their first dose by age 13. Not coincidentally Rhode Island is the only state requiring HPV vaccine for both male and female students, starting with the first dose by 7th grade. Virginia and Washington, DC, have requirements just for females.

The good news is that nationwide vaccination rates steadily rose from 22% getting the first dose by age 13 in 2013 to 34% in 2016. But why are vaccination rates still well below 50% in most states? A BCBSA-commissioned survey of over 700 parents of adolescents aged 10-13 revealed the following top three reasons for parents not vaccinating their child against HPV:

  • Being concerned about adverse side effects (59.4%)
  • Not thinking their child is at risk (23.6%)
  • Not knowing their child needed an HPV vaccination (15.7%)

Is requiring the HPV vaccine the solution? One argument against making the HPV vaccine mandatory is that people should be allowed freedom of choice. When Rhode Island first introduced its requirement, protests resulted various groups such as parents, a 2,400-member plus Facebook group, and the American Civil Liberties Union.

However, the counter-argument is that freedom of choice does not always hold when in the words of Spock, “the needs of the many outweigh the needs of the few.” You aren’t free to run up and down the aisle of an airplane naked and screaming because the needs of other on the plane outweigh the needs of you. Similarly, the HPV vaccine could help slow and even stop the transmission of HPV throughout the population, which can result in cancers that not only affect the cancer victims but also society by adding to health care costs.

Here is a Today show segment on the HPV vaccine:

Also, when a child doesn’t get vaccinated, it is usually because of the parent’s choice and not the child’s. Could making the vaccine mandatory in fact be protecting the child?

Another argument used by some is that the HPV vaccine has adverse effects. There are websites claiming that HPV vaccine can cause “crippling side effects” and “death.” But many of these scarier claims are not supported by rigorous scientific evidence. (Note: there are also websites that say that the Earth is flat, Elvis was an alien, and the government controls the weather). While nothing is completely safe (e.g., even a chocolate chip cookie in the right situation could do some real damage) and all vaccines do have their risks, the risks of the HPV vaccine are comparatively very low and far outweighed by the potential benefits as indicated by the CDC.

As I wrote before for Forbes, some have argued that the HPV vaccine is a “gateway to sex” and thus making it mandatory would increase the number of teenagers having sex and encourage promiscuity. However, this goes counter to the recent trend of teenagers delaying when they first have sex and suggests that teenagers would not have sex if it weren’t for that darn HPV vaccine. A related argument is that the HPV vaccine would give teens a false sense of security that they are protected against all sexually transmitted infections, leading them to not practice safe sex. However, raising awareness of what the HPV vaccine actually does could help overcome this concern.

All of this does not necessarily mean that making HPV vaccination mandatory is the solution. However, what then is the solution to a majority of adolescents still not getting vaccinated (at least by age 13 and when sexual activity for some begin)? As Haywood described, this is a situation in which many are “not taking full advantage of preventive measures. A big issue is lack of awareness of the HPV vaccine and its benefits.” HPV vaccine awareness campaigns may help push up vaccination rates, but by how much?

The wonderfully straight-forward and transparent world of politics will help determine whether Senate Bill 1558 becomes a law in Florida. A similar bill failed to pass in 2011. But things have changed since 2011, in good ways and bad.

Living with cancer in the country: Many Wyoming residents must leave home to seek the care they need

Source: trib.com
Author: Katie King

Bob Overton is all too familiar with the 140-mile stretch of land between Thermopolis and Casper.

He and his wife, Sherry, made the two-hour trip in their white pickup dozens of times while Bob was undergoing treatment for lymphoma in 2015. Even with the help of Alan Jackson and Martina McBride’s music, the hours still lagged, with nothing to stare at except endless grassy plains.

“That trip is pretty monotonous, and it doesn’t get any better with time,” he recalled.

But the couple didn’t have a choice. Their hometown of Thermopolis, population 3,009, doesn’t offer the care Bob needed.

And the Overtons aren’t alone.

As the least populated state in the country, Wyoming appeals to those in search of space and wilderness. But the peace and quiet comes with drawbacks: Services that urban residents may take for granted, like advanced medical care, aren’t readily available for thousands of people living in small towns and rural areas.

Many of those battling cancer in Wyoming subsequently end up seeking treatment in Casper, according to Rocky Mountain Oncology’s Patient Navigator Sam Carrick. She said the center is the only medical facility in the state that offers radiation, chemotherapy and Positron emission tomography scans.

Other areas may offer one or two of those services, but many prefer the convenience of a one-stop shop, she said.

About 15 percent of their patients are from out-of-town, added Carrick, who is responsible for guiding all patients through the treatment process. She said it’s often devastating for people to learn that they can’t get the care they need at home.

“First you are hit over the head with a diagnosis that you didn’t want, and then you can’t get treatment at home, so you have to travel and be away from your family members or pets,” she said.

Some patients drive back-and-forth, but temporarily relocating often becomes necessary during the more intensive treatment phases.

And that was the case with Bob. The 75-year-old initially remained in Thermopolis, only traveling to Casper for intermittent doses of chemotherapy. But he said that wasn’t possible while he was undergoing radiation, which he needed daily for 30 days.

Sherry remembers breaking down into tears when she realized they had to leave home. Already faced with the possibly of losing her husband, not to mention mounting medical bills, the thought of relocating for a month was overwhelming.

“That was just more than I could handle … I just thought, ‘How are we going to do this?’” she said.

Battling cancer is difficult for anyone, but those living far away from treatment centers need extra help, said Wyoming Foundation for Cancer Care treasurer Kara Frizell. Finding the money for gas and hotel accommodations can quickly become a serious problem.

“It’s not something you can just come up with,” she explained.

Frizell said the Casper-based charity annually spends between $20,000 and $30,000 assisting patients with necessary travel expenses. The nonprofit also oversees a network of volunteers, called Angels, who help out-of-towners feel at home by delivering meals or dropping off gift baskets.

Robert Rasmussen also lives in Rawlins, but he hasn’t had much of a chance to grow attached to the town. He moved from Tuscon, Arizona, in search of peace and quiet. But about a year after moving, he was diagnosed with stage four throat cancer last fall. It quickly became apparent that traveling back and forth to Casper for treatment wasn’t a safe option.

Sitting in his bed in January at the Shepherd of the Valley Healthcare Community — where he’s recovering from surgery — the emaciated 50-year-old removed his oxygen mask and explained that intense radiation and chemotherapy treatments left him far too nauseous and exhausted to drive.

Rasmussen temporarily relocated to Casper in October and brought along his dog, Piggy. The Australian Shepherd is family, and he couldn’t bear to be without her.

“She’s the only thing that keeps me together,” he explained.

Although Rasmussen was worried hotels wouldn’t allow animals, Carrick arranged for both patient and pet to stay at the Sleep Inn in Evansville. The patient navigator also connected him with the cancer foundation to help with the bill.

The hotel staff has since fallen in love with Piggy, according to general manager Carmen Bartow. Employees walk her each day, sneak her treats from the breakfast buffet and even take her to visit her dad.

“She’s our mascot,” said Bartow.

The manager said the inn annually receives about 15 guests who are in town for cancer treatments, likely because of their close proximity to the oncology center. The hotel offers discounted rates for its sick visitors and employees try to help them out in any way possible.

“If we can’t help one another out then there is something wrong with us,” she said.

Rasmussen greatly appreciates everyone who made it possible for Piggy to stay in Casper.

His condition is serious, and distracting himself from the possibly of death isn’t easy, he explained. Surrounded by feeding tubes and beeping monitors, it’s impossible to forget his situation.

“I try to read or watch TV or just focus on something different, but when I’m just sitting here by myself, it’s hard,” he said.

But Rasmussen said he can manage with Piggy by his side for support.

Although his former home in Tuscon was closer to advanced medical care, Rassmussen said he prefers living in small towns because its safer and more peaceful.

“I don’t have any regrets [about moving],“ he said. “City life isn’t for everybody.”

Biofilms in tonsil crypts may explain HPV-related head and neck cancers

How can human papilloma virus (HPV) be prevalent in otherwise healthy people not known to carry it? A just-published study concludes that the virus may be lurking in small pockets on the surface of their tonsils.

Researchers from University of Rochester Medical Center (URMC) found HPV encased in biofilms inside tonsil crypts, where HPV-related head and neck cancers often originate. HPV is shed from the tonsil during an active infection and gets trapped in the biofilm, where it may be protected from immune attack.

In the crypts, the virus likely lays in wait for an opportunity to reinstate infection or invade the tonsil tissue to develop cancer.

“The virus gains access to the basal layer of stratified squamous epithelium through structural breaks in the stratified epithelial superstructure,” the investigators reported in the study. “Tonsillar crypt reticulated epithelium itself has been shown to contain numerous small blood vessels and has a discontinuous basement membrane, which may facilitate this infection and reinfection process.”

The URMC researchers said their finding could help prevent oropharyngeal cancers that form on the tonsils and tongue—and may explain why the roughly 5% of HPV-infected people who develop cancer of the mouth or throat are not protected by their immune systems.

HPV 16 and 18, high-risk strains that are known to cause cervical cancer, also cause head and neck cancers. While verified tests can detect HPV in people before they develop cervical cancer, that’s not the case with head and neck cancers, which according to a 2016 study are expected to outnumber cervical cancer cases by 2020.

“Far-Reaching Implications”
“Given the lack of universal HPV immunization and the potential for the virus to evade the immune system, even in individuals with detectable HPV in their blood, our findings could have far-reaching implications for identifying people at risk of developing HPV-related head and neck cancers and ultimately preventing them,” Matthew Miller, M.D., associate professor of otolaryngology and neurosurgery at URMC, said in a statement.

Dr. Miller and six colleagues detailed their findings in “Prevalence of High-Risk Human Papillomavirus in Tonsil Tissue in Healthy Adults and Colocalization in Biofilm of Tonsillar Crypts,” published online January 25 in JAMA Otolaryngology-Head & Neck Surgery, and announced by URMC today. The study’s corresponding author is Katherine Reith, M.D., an otolaryngology resident at URMC.

The researchers carried out a retrospective, cross-sectional study using samples obtained from tonsils archived at a university hospital following elective nononcologic tonsillectomy from 2012 to 2015. The samples consisted of formalin-fixed, paraffin-embedded samples of tumor-free tonsil tissue from 102 adults who had elective tonsillectomies and were between ages 20 and 39. More than half the patients (55, or 53.9%) were female.

Five of the samples contained HPV and four contained HPV 16 and 18. In every case, HPV was found in tonsil crypts biofilms.

HPV status was assessed by polymerase chain reaction (PCR), and high-risk subtypes 16 and 18 were assessed with quantitative PCR assay. Samples that demonstrated presence of HPV were then analyzed by in situ hybridization to localize the viral capsid protein.

These samples were then stained with concanavalin A to establish biofilm presence and morphology and with 4′,6-diamidino-2-phenylindole (DAPI) to visualize location of the virus in relation to cell nuclei. Data was assembled for aggregate analysis to colocalize HPV in the biofilm of the tonsillar crypts, the URMC researchers reported.

The research team plans to develop topical antimicrobials designed to disrupt the biofilm and allow the immune system to clear the virus—part of their investigation of potential screening tools, such as an oral rinse, to detect HPV in the mouth and throat.

NHS immunises girls but not boys against potentially deadly HPV virus because its ‘not cost-effective’

Girls aged 12 to 13 are already vaccinated for free against the HPV virus, which can cause deadly tumours in the throat and mouth, but boys have to do without.

Experts believe it would take £22 million a year to vaccinate every boy in Britain against the deadly disease – a fraction of the vast £148 billion NHS budget. But low overall infection rates mean that bean-counters refuse to sign off on any additional funding – condemning thousands to months of expensive, agonising cancer treatment.

Cambridge University Professor Margaret Stanley blasted: “You cannot protect against these cancers by only vaccinating half the population.”

She told the Mail on Sunday: “Not to immunise boys is classic Treasury short-termism. You may not spend so much now, but it will cost far more years later.

“We are in the midst of an HPV pandemic.”

HPV is generally spread through genital and oral sex, and can also be transmitted by kissing – meaning that some people who contract it are virgins. Only a tiny minority of those infected go on to develop cancer, often decades after they contract the virus. An estimated 80 per cent of all adults in the UK have been infected at some point.

Throat and cancer specialist Professor Christopher Nutting said: “My patients are being struck down by a preventable cancer that will affect them for the rest of their lives.

“It’s unfair that women are protected but men are not. The vaccine will work. It is starting to make cervical cancer incredibly rare. Why wouldn’t we do the same for cancer of the throat?’

Figures show that in 2011 alone the HPV virus triggered cancers in 1,850 people – and a staggering 1,400 of those were men.

Businessman Chris Curtis, 59, who contracted oropharyngeal cancer after becoming infected, said: “There is something out there that can stop this happening. We’ve got to use it.”

Opening up about his harrowing time with the disease, he said: “My family would eat in the dining room and I would be stuck being fed through my tube by machine.

“I planned suicide twice. All that stopped me was the thought of my kids.

“You’ve seen the cream-cracker challenge? ” live with that every minute of every day. I look at a burger and chips and I see cardboard. If I eat a tomato, it feels like it’s exploding in my mouth – it’s intolerable.

“For months the cancer takes over your life, and there is no respite. It tests you to breaking point.”

Prof Pollard, of the NHS Joint Committee on Vaccination and Immunisation, said the committee could only recommend vaccinating boys if it found this conformed with the “health technology assessment methodology’, which is derived from the Treasury’s ‘Green book’.

“Under the rules we are only looking at cost-effectiveness from the health providers’ perspective.”

“Each possible vaccine had to be considered in the context of the NHS as a whole”
