Abstract Unplanned radiation treatment breaks and prolongation of the radiation treatment time are associated with lower survival and locoregional control rates when radiotherapy or concurrent chemoradiotherapy is used in the curative treatment of head and neck cancer. Treatment of head and neck cancer is intense, involving high-dose, continuous radiotherapy, and often adding chemotherapy to radiotherapy. As the intensity of treatment regimens has escalated in recent years, clinical outcomes generally have improved. However, more intensive therapy also increases the incidence of treatment-related toxicities, particularly those impacting the mucosal lining of the oral cavity, pharynx, and cervical esophagus, and results in varying degrees of ulcerative mucositis. Ulcerative mucositis is a root cause of unscheduled radiation treatment breaks, which prolongs the total radiation treatment time. Alterations in radiotherapy and chemotherapy, including the use of continuous (i.e., 7 days/week) radiotherapy to ensure constant negative proliferative pressure, may improve efficacy outcomes. However, these approaches also increase the incidence of ulcerative mucositis, thereby increasing the incidence of unplanned radiation treatment breaks. Conversely, the reduction of ulcerative [...]

Cessation of alcohol drinking, tobacco smoking and the reversal of head and neck cancer risk

Source: International Journal of EpidemiologyAccepted September 28, 2008 Abstract Background Quitting tobacco or alcohol use has been reported to reduce the head and neck cancer risk in previous studies. However, it is unclear how many years must pass following cessation of these habits before the risk is reduced, and whether the risk ultimately declines to the level of never smokers or never drinkers. Methods We pooled individual-level data from case–control studies in the International Head and Neck Cancer Epidemiology Consortium. Data were available from 13 studies on drinking cessation (9167 cases and 12 593 controls), and from 17 studies on smoking cessation (12 040 cases and 16 884 controls). We estimated the effect of quitting smoking and drinking on the risk of head and neck cancer and its subsites, by calculating odds ratios (ORs) using logistic regression models. Results Quitting tobacco smoking for 1–4 years resulted in a head and neck cancer risk reduction [OR 0.70, confidence interval (CI) 0.61–0.81 compared with current smoking], with the risk reduction due to smoking cessation after ≥20 years (OR 0.23, CI 0.18–0.31), reaching the level of never smokers. For alcohol use, a beneficial effect on the risk of head and neck cancer was only observed after ≥20 years of quitting (OR 0.60, CI 0.40–0.89 compared with current drinking), reaching the level of never drinkers. Conclusions Our results support that cessation of tobacco smoking and cessation of alcohol drinking protect against the development of head and neck cancer.

SSRI Prevents Depression in Head, Neck Cancer

Source: MedPage TodayBy Salynn Boyles, Contributing WriterPublished: June 21, 2013 Prophylactic escitalopram cut the incidence of depression in head and neck cancer patients by more than 50% and improved quality of life, a clinical trial showed. Significantly fewer patients taking the antidepressant developed depression, when compared with those on placebo (10% vs 24.6%; stratified log-rank test, P=.04), according to a study in the June 20 issue of JAMA Otolaryngology Head and Neck Surgery. "Depression is very common among patients with this disease, but it is not easy to predict who will become depressed at the beginning of treatment," University of Nebraska Medical Center professor of head and neck oncology William Lydiatt, MD, told MedPage Today. "That's why the prevention paradigm may offer considerable benefit at an acceptable risk." As many as half of head and neck cancer patients develop clinical depression within months of their diagnosis and suicide rates are among the highest in patients with a medical illness, Lydiatt noted. "The burden of treatment is extensive and frequently includes dysphagia, disfigurement, voice alterations, mucositis, need for tracheostomy and feeding tubes, fatigue and depression," the researchers wrote. They chose the generic version of the popular SSRI Lexapro for the trial to give patients an affordable treatment option that's well tolerated in the elderly. The randomized, double-blind trial included 148 newly diagnosed head and neck cancer patients entering treatment who did not yet have a diagnosis of depression. The patients were stratified by sex, site of disease, stage, and primary modality of [...]

Teen HPV Rates Were Cut In Half After The Vaccine Went Public

Source ThinkProgress.orgBy Annie-Rose Strasser Published Jun 19, 2013 at 2:35 pm Following the 2006 introduction of a vaccine against cancer-causing human papillomavirus, rates of HPV in teen girls have plummeted to nearly half, a new study found on Wednesday. The Journal of Infectious Diseases reports that HPV infection in girls ages 14 to 19 dropped from 11.5 percent for the years 2003-2006 to 5.1 percent for 2007-2010. Since HPV can lead to cervical cancer, the results also could herald a drop in cancer rates for girls in this age range, too. The study illustrates a great advancement in public health, but it also underlines the consequences for those huge numbers of women and girls who are still not getting their vaccinations; in 2011, only 35 percent of girls ages 13-17 received all three shots in the vaccination series, and only 30 percent of women ages 19-26 had received the vaccine. Fear-mongering and conspiracy theories over the side effects of the HPV vaccine are a major reason that inoculation rates are so low. While the Centers for Disease control have deemed the shots safe, and especially effective for young girls, 16 percent of parents report not letting their children get the shots for fear of side effects. In fact, incidents of cancer from HPV are rising in the U.S., and the CDC says rates of inoculation are “unacceptably low.” These dangerous theories are fueled by conservatives like Rep. Michele Bachmann (R-MN), who campaigned on her insistence that HPV vaccines cause “mental [...]

Vaccine is credited with steep fall of HPV in teenagers.

Source The New York TimesBy SABRINA TAVERNISEPublished: June 19, 2013 342 Comments The prevalence of dangerous strains of the human papillomavirus — the most common sexually transmitted infection in the United States and a principal cause of cervical cancer — has dropped by half among teenage girls in recent years, a striking measure of success for a vaccine against the virus that was introduced only in 2006, federal health officials said on Wednesday. Dr. Judith L. Schaechter gives an HPVvaccination to a 13-year-old girl in heroffice at the University of Miami LeonardM. Miller School of Medicine. The sharp decline in the infection rate comes at a time of deepening worry among doctors and public health officials about the limited use of the HPV vaccine in the United States. Health departments across the country are scrambling for ways to increase vaccination rates, while nonprofit groups are using postcard reminders and social media campaigns and pediatricians are being encouraged to convince families of the vaccine’s benefits. There are some signs that resistance to the vaccine may be growing. A study published in the journal Pediatrics in March found that 44 percent of parents in 2010 said they did not intend to vaccinate their daughters, up from 40 percent in 2008. Because it prevents a sexually transmitted infection, the vaccine comes with a stigma. Some parents worry it promotes promiscuity. And it has been controversial. During the Republican primary in 2011, Representative Michele Bachmann, Republican of Minnesota, said the vaccine could have [...]

Reasons for Not Vaccinating Adolescents: National Immunization Survey of Teens, 2008–2010

Source: PediatricsAuthors: Paul M. Darden, MD, David M. Thompson, PhD, James R. Roberts, MD, MPH, Jessica J. Hale, MSa, Charlene Pope, PhD, MPH, RN, Monique Naifeh, MD, MPHa, and Robert M. Jacobson, MDPublished Online: March 18, 2013 Abstract OBJECTIVE: To determine the reasons adolescents are not vaccinated for specific vaccines and how these reasons have changed over time. METHODS: We analyzed the 2008–2010 National Immunization Survey of Teens examining reasons parents do not have their teens immunized. Parents whose teens were not up to date (Not-UTD) for Tdap/Td and MCV4 were asked the main reason they were not vaccinated. Parents of female teens Not-UTD for human papillomavirus vaccine (HPV) were asked their intent to give HPV, and those unlikely to get HPV were asked the main reason why not. RESULTS: The most frequent reasons for not vaccinating were the same for Tdap/Td and MCV4, including “Not recommended” and “Not needed or not necessary.” For HPV, the most frequent reasons included those for the other vaccines as well as 4 others, including “Not sexually active” and “Safety concerns/Side effects.” “Safety concerns/Side effects” increased from 4.5% in 2008 to 7.7% in 2009 to 16.4% in 2010 and, in 2010, approaching the most common reason “Not Needed or Not Necessary” at 17.4% (95% CI: 15.7–19.1). Although parents report that health care professionals increasingly recommend all vaccines, including HPV, the intent to not vaccinate for HPV increased from 39.8% in 2008 to 43.9% in 2010 (OR for trend 1.08, 95% CI: 1.04–1.13). CONCLUSIONS: Despite doctors increasingly recommending adolescent vaccines, parents [...]

NIH scientists find promising biomarker for predicting HPV-related oropharynx cancer

Source: National Cancer InstitutePublished: 6-17-13 Researchers have found that antibodies against the human papillomavirus (HPV) may help identify individuals who are at greatly increased risk of HPV-related cancer of the oropharynx, which is a portion of the throat that contains the tonsils. In their study, at least 1 in 3 individuals with oropharyngeal cancer had antibodies to HPV, compared to fewer than 1 in 100 individuals without cancer. When present, these antibodies were detectable many years before the onset of disease. These findings raise the possibility that a blood test might one day be used to identify patients with this type of cancer. Genomic structure of HPV The results of this study, carried out by scientists at the National Cancer Institute (NCI), part of the National Institutes of Health, in collaboration with the International Agency for Research on Cancer (IARC), were published online June 17, 2013, in the Journal of Clinical Oncology. Historically, the majority of oropharyngeal cancers could be explained by tobacco use and alcohol consumption rather than HPV infection. However, incidence of this malignancy is increasing in many parts of the world, especially in the United States and Europe, because of increased infection with HPV type 16 (HPV16). In the United States it is estimated that more than 60 percent of current cases of oropharyngeal cancer are due to HPV16. Persistent infection with HPV16 induces cellular changes that lead to cancer. HPV E6 is one of the viral genes that contribute to tumor formation. Previous [...]

Sexual Activity–Related Outcomes After Human Papillomavirus Vaccination of 11- to 12-Year-Olds

Source: PediatricsPublished Online: October 15, 2012By: Robert A. Bednarczyk, PhD, Robert Davis, MD, MPH, Kevin Ault, MD, Walter Orenstein, MD, and Saad B. Omer, MBBS, PhD, MPH ABSTRACT: OBJECTIVE: Previous surveys on hypothesized sexual activity changes after human papillomavirus (HPV) vaccination may be subject to self-response biases. To date, no studies measured clinical markers of sexual activity after HPV vaccination. This study evaluated sexual activity–related clinical outcomes after adolescent vaccination. METHODS: We conducted a retrospective cohort study utilizing longitudinal electronic data from a large managed care organization. Girls enrolled in the managed care organization, aged 11 through 12 years between July 2006 and December 2007, were classified by adolescent vaccine (HPV; tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis, adsorbed; quadrivalent meningococcal conjugate) receipt. Outcomes (pregnancy/sexually transmitted infection testing or diagnosis; contraceptive counseling) were assessed through December 31, 2010, providing up to 3 years of follow-up. Incidence rate ratios comparing vaccination categories were estimated with multivariate Poisson regression, adjusting for health care–seeking behavior and demographic characteristics. RESULTS: The cohort included 1398 girls (493 HPV vaccine–exposed; 905 HPV vaccine–unexposed). Risk of the composite outcome (any pregnancy/sexually transmitted infection testing or diagnosis or contraceptive counseling) was not significantly elevated in HPV vaccine–exposed girls relative to HPV vaccine–unexposed girls (adjusted incidence rate ratio: 1.29, 95% confidence interval [CI]: 0.92 to1.80; incidence rate difference: 1.6/100 person-years; 95% CI: −0.03 to 3.24). Incidence rate difference for Chlamydia infection (0.06/100 person-years [95% CI: −0.30 to 0.18]) and pregnancy diagnoses (0.07/100 person-years [95% CI: −0.20 to 0.35]), indicating little [...]

E-Cigarettes Are in Vogue and at a Crossroads

By LIZ ALDERMANPublished: June 12, 2013Source: NY Times PARIS — On a recent day in the shadow of the Arc de Triomphe, a line of 20 people spilled onto the sidewalk of a trendy new boutique, eager to get a taste of its latest gourmet offerings. Olivia Foiret, the manager of ClopiNette, demonstrates filling an e-cigarette for a client. A sign in the window promoted piña colada as the store’s flavor of the month. A woman wearing a Chanel jacket said she wanted to try peach. But this was no temple of gastronomy. It was one of scores of electronic cigarette shops that have been springing up by the week in Paris as well as in numerous cities across Europe and the United States. Inside the ClopiNette boutique, shoppers can choose from among more than 60 flavors of nicotine liquid — including Marlboro and Lucky Strike flavors — all in varying strengths and arranged in color-coded rows. (ClopiNette is a play on “clope,” French slang for a cigarette.) “It’s like visiting a Nespresso store,” said Anne Stephan, a lawyer specializing in health issues at a nearby law firm. What’s driving her into the store is a desire shared by many: they want to give up smoking tobacco but don’t want to kick the smoking habit. After smoking 20 cigarettes daily for 25 years and failing to quit, Ms. Stephan said she had cut down to one a day in the three months since she began puffing on a so-called e-cig. Using [...]

Oral cancer sneaks up

Source: well.blogs.nytimes.com Author: Donald G. McNeail Jr. and Anahad O'Connor The actor Michael Douglas has done for throat cancer what Rock Hudson did for AIDS and Angelina Jolie did for prophylactic mastectomy. By asserting last week that his cancer was caused by a virus transmitted during oral sex, Mr. Douglas pushed the disease onto the front pages and made millions of Americans worry about it for the first time. In this case, it was a subset of Americans who normally worry more about being killed by cholesterol than by an S.T.D. The typical victim is a middle-aged, middle-class, married heterosexual white man who has had about six oral sex partners in his lifetime. The virus, human papillomavirus Type 16, also causes cervical cancer. So is there any early oral screening that a man can have — an equivalent to the Pap smear, which has nearly eliminated cervical cancer as a death threat in this country? The answer, according to cancer experts and a recent opinion from the United States Preventive Services Task Force, is no. And for surprising reasons. The Pap test — invented in 1928 by Dr. George N. Papanicolaou — involves scraping a few cells from the cervix and checking them under a microscope for precancerous changes. Precancerous cells have a “halo” around the nucleus, while cancerous ones have larger, more colorful nuclei, said Dr. Paul D. Blumenthal, a professor of gynecology at Stanford University Medical School. In theory, it should be similarly easy to scrape and examine [...]
