Incidence of second primary cancers in adult cancer survivors

Source: ascopost.com Author: Matthew Stenger In a Danish population-based retrospective cohort study reported in The Lancet Oncology, Kjaer et al identified the cumulative incidence of second primary cancers among cancer survivors aged ≥ 40 years who were alive 1 year after diagnosis. Study Details The study involved data from 457,334 patients diagnosed with 27 types of cancer between January 1997 and December 2014. Follow-up was from date of first cancer diagnosis and lasted up to 24 years, ending in December 2020. Key Findings Among all survivors, the cumulative incidence of second primary cancer was 6.3% (95% confidence interval [CI] = 6.2%–6.4%) at 5 years after diagnosis, 10.5% (95% CI = 10.4%–10.6%) at 10 years after diagnosis, and 13.5% (95% CI = 13.4%–13.7%) at 15 years after diagnosis. The highest cumulative incidence of second primary cancer at 10 years after diagnosis was among survivors of laryngeal cancer (21.8%), oropharyngeal and oral cavity cancer (19.5%), and bladder and urinary tract cancer (18.5%). Most cancer types (17 of the 27 investigated) were associated with a 10-year cumulative incidence of second primary cancer between approximately 10% and 15%. Survivors of liver (2.5%), pancreatic (2.5%), and lung cancer (3.9%) had the lowest 10-year cumulative incidence of second primary cancer. Lung cancer was the most frequent or second most frequent second primary cancer for 7 of the 10 primary cancer types associated with the highest 10-year cumulative incidence of second primary cancer. The sites of second primary cancer varied among patients with the remainder of the [...]

Detecting suspicious lesions: what do I say next?

Source: dentistry.co.uk Author: Philip Lewis Dental team members are amazing. They put patients at their ease and provide treatment for their dental issues. They improve smiles, boost self-confidence and they save lives. Yes, you read that right. There aren’t many opportunities for dental team members to be lifesavers. Detecting mouth cancer at an early stage is one of them. It’s an initiative for the whole dental team. Both clinical and non-clinical team members have a vital part to play. From a receptionist noticing changes in a patient’s voice, a practice manager spotting a swelling they haven’t seen before to a clinician picking up on a soft-tissue abnormality, we all get the chance to be pivotal in protecting a patient’s wellbeing. Risk factors We know there are risk factors we should be aware of: the use of tobacco in any form, regular use of alcohol, especially spirits, social deprivation with its associated problems of nutrition and vitamin deficiency. It is understood that increasing age is a factor and that men are more likely than women to get the disease. We appreciate the significant effects of infection that certain strains of HPV have had recently but realise how important it is to examine all adults. Many sufferers have no identifiable risk factors. During the clinical examination, we’ll be looking for anything unusual, including: Red, white or mixed patches Ulcers that don’t heal within a maximum of three weeks Swellings Changes to normal appearance or texture and lumps in the face or neck [...]

Testimony by otolaryngologists in defense of tobacco companies 2009–2014

Source: www.onlinelibrary.wiley.comAuthor: Robert K. Jackler, MD Abstract Objectives/Hypothesis To examine expert testimony offered by otolaryngologists in defense of the tobacco industry and to assess whether opinions rendered were congruent with evidence in the scientific literature. Methods Data sources include publically available expert witness depositions and trial testimony of board-certified otolaryngologists employed by the tobacco industry in defense of lawsuits brought by smokers suffering from head and neck cancer. The cases, adjudicated in Florida between 2009 and 2014, focused on whether smoking caused the plaintiff's cancer. Results The study includes nine legal cases of upper aerodigestive tract cancer involving six otolaryngologists serving as expert witnesses for the tobacco industry. Cancer sites included larynx (5), esophagus (2), mouth (1), and lung (1). Five of the six otolaryngologists consistently, over multiple cases, offered opinions that smoking did not cause the plaintiff's cancer. By highlighting an exhaustive list of potential risk factors, such as human papillomavirus (HPV), alcohol, asbestos, diesel fumes, salted fish, mouthwash, and even urban living, they created doubt in the minds of the jurors as to the role of smoking in the plaintiff's cancer. Evidence shows that this testimony, which was remarkably similar across cases, was part of a defense strategy shaped by tobacco's law firms. Conclusions A small group of otolaryngologists regularly serve as experts on behalf of the tobacco industry. Examination of their opinions in relation to the scientific literature reveals a systematic bias in interpreting the data relating to the role played by smoking in head and neck [...]

DNA shed from head and neck tumors detected in blood and saliva

Source: www.medicalexpress.comAuthor: Wang et al., Science Translational Medicine (2015) Schematic showing the shedding of tumor DNA from head and neck cancers into the saliva or plasma. Tumors from various anatomic locations shed DNA fragments containing tumor-specific mutations and human papillomavirus DNA into the saliva or the circulation. The detectability of tumor DNA in the saliva varied with anatomic location of the tumor, with the highest sensitivity for oral cavity cancers. The detectability in plasma varied much less in regard to the tumor’s anatomic location. Credit: Wang et al., Science Translational Medicine (2015) On the hunt for better cancer screening tests, Johns Hopkins scientists led a proof of principle study that successfully identified tumor DNA shed into the blood and saliva of 93 patients with head and neck cancer. A report on the findings is published in the June 24 issue of Science Translational Medicine. "We have shown that tumor DNA in the blood or saliva can successfully be measured for these cancers," says Nishant Agrawal, M.D., associate professor of otolaryngology—head and neck surgery—and of oncology at the Johns Hopkins University School of Medicine. "In our study, testing saliva seemed to be the best way to detect cancers in the oral cavity, and blood tests appeared to find more cancers in the larynx, hypopharynx and oropharynx. However, combining blood and saliva tests may offer the best chance of finding cancer in any of those regions." Agrawal explains that inborn genetic predispositions for most head and neck cancers are rare, but [...]

Alcohol drinking in never-tobacco users and cigarette smoking in never drinkers: pooled analysis in the International Head and Neck Cancer Epidemiology (INHANCE) consortium

Source: http://cancerres.aacrjournals.orgAuthors: Paolo Boffetta, Mia Hasibe & On Behalf Of INHANCE Consortium Abstract: Cigarette smoking and alcohol drinking account for at least 75% of head and neck cancers. A precise understanding of the independent effect of each of these factors in the absence of the other has important implications, in terms of elucidating the mechanisms of head and neck carcinogenesis and assessing the effect of interventions aimed to control either risk factor.We determined the extent to which head and neck cancer is associated with cigarette smoking among never-drinkers and alcohol drinking among never-tobacco users. We pooled individual-level data across 15 individual case-control studies including 10,244 head and neck cancer cases and 15,227 controls.There were 1,072 cases and 5,775 controls who never used tobacco, and 1,598 cases and 4,051 controls who never drank alcohol. Cigarette smoking increased the risk of head and neck cancers [odds ratio (OR)=2.10, 95% confidence interval (CI) 1.49-2.95] among never-drinkers, with clear dose-response relationships for frequency, duration and packyears of cigarette smoking. Approximately 24% of head and neck cancer cases among non-drinkers would have been prevented if these individuals had not smoked cigarettes. Among never-tobacco users, an increasing risk of head and neck cancer was detected for increasing alcohol drinking frequency (p for trend<0.001), but the effect was apparent only at high doses.Our results represent the most precise estimate available of the independent effect of each of the two main risk factors of head and neck cancer and exemplify the strengths of large-scale consortia in cancer epidemiology. *This news [...]

Study finds low public awareness of head and neck cancer

Source: www.sciencecodex.comAuthor: The JAMA Network Journals Bottom Line: Public awareness of head and neck cancer (HNC) is low, with few Americans knowing much about risk factors such as tobacco use and human papillomavirus (HPV). Author: Alexander L. Luryi, B.S., of the Yale University School of Medicine, New Haven, Conn. Background: HNC is the 10 th most common cancer in the United States. It is a potentially preventable disease with about 75 percent of cases caused by tobacco use. In recent years, HPV has been established as a risk factor for HNC. Increased public awareness of HNC and its risk factors could help improve outcomes. How the Study Was Conducted: An online study of 2,126 adults was conducted in 2013. Results: About 66 percent of the participants were "not very" or "not at all" knowledgeable about HNC. Smoking and chewing or spitting tobacco were identified by 54.5 percent and 32.7 percent of respondents as risk factors for mouth and throat cancer, respectively. Only 0.8 percent of respondents identified HPV as a risk factor. Discussion: "Awareness of HNC is low compared with other cancers, which is concerning given the importance of risk factor avoidance and modification, as well as early patient detection, as drivers of prevention and improved outcomes." *This news story was resourced by the Oral Cancer Foundation, and vetted for appropriateness and accuracy.

Most head, neck surgeons discuss risk factors, HPV

Source: www.doctorslounge.com Author: staff Most head and neck surgeons discuss risk factors for head and neck cancer, including human papillomavirus (HPV), with their patients, according to a study published online Aug. 29 in JAMA Otolaryngology-Head & Neck Surgery. Kelly M. Malloy, M.D., from the University of Michigan in Ann Arbor, and colleagues conducted an online survey of 297 members of the American Head and Neck Society (AHNS) to assess knowledge, attitudes, and beliefs regarding HPV education and vaccination. The researchers found that the majority (more than 90 percent) of respondents reported discussing risk factors for head and neck cancer, including HPV as a specific risk factor. About half (49.1 percent) reported discussing the importance of vaccinating preadolescents for HPV, with 38.7 percent not relating to this issue because their patients are adults. More than two-thirds (68.9 percent) of the respondents with daughters reported that their daughters had received or were scheduled to receive the HPV vaccine. For respondents with sons, only 55.8 percent reported that their sons had been vaccinated or that they intended for them to be vaccinated. Attitudes toward HPV vaccine safety and efficacy were divergent. There was considerable support of potential future AHNS activities relating to education, increasing public awareness, and advocacy of health policy related to HPV. "Head and neck surgeons are knowledgeable about HPV and show generally positive attitudes and beliefs about HPV education and vaccination," the authors write. "They endorse AHNS actions to improve public and patient education, as well as health policy on [...]

Survey reveals most are unaware of the causes and symptoms of mouth cancer

Source: www.cosmeticdentistryguide.co.uk Author: staff A survey has revealed that most people are unaware of the major risk factors and symptoms of oral cancer. The SimplyHealth Annual Dental Health Survey revealed that of the 11,785 adults surveyed, 70 percent were unaware of the symptoms of mouth cancer while only 3 percent knew that kissing could increase your risk of moth cancer as a result of exposure to the human papilloma virus (HPV). A spokesperson for SimplyHealth said that most were aware that smoking and drinking increased the risk of oral cancer, but very few people were aware of the link between oral cancer and the HPV, a virus which is also responsible for some cases of cervical cancer. According to Cancer Research UK, some strains of HPV increase the risk of mouth cancer, which could explain why the disease is becoming more common in young people, as the virus is spread through physical contact. Dentist Michael Thomas said that it was important for people to be aware of the symptoms of mouth cancer, as well as the causes. As with most forms of cancer, the earlier mouth cancer is diagnosed, the higher the chance of survival. Only 28 percent of adults surveyed had discussed mouth cancer with their dentist and this is worrying, as dentists are in a prime position to spot the early warning signs and arrange further tests and treatment. The most common symptoms of mouth cancer include lumps or swellings in the mouth or throat, sores or ulcers [...]

Global oral cancer rates to rise 63% by 2030

Source: www.drbicuspid.com Author: DrBicuspid Staff The International Agency for Research on Cancer, part of the World Health Organization (WHO), predicts that more than 790,000 people worldwide will be diagnosed with oral cancer by 2030, an increase of more than 63% compared with 2008. Mortality rates for mouth cancer are predicted to be even higher with more than 460,000 deaths forecast by 2030, more than 67% higher than 2008 rates, according to the International Dental Health Foundation (IDHF). The WHO believes modifying and avoiding risk factors could result in up to 30% of cancers being avoided, noted Nigel Carter, BDS, chief executive of the IDHF. "Although cancer is not wholly preventable, mouth cancer is very closely related to lifestyle choices. Making more people aware of the risks and symptoms for mouth cancer will undoubtedly save lives," Dr. Carter stated in a press release. "Forecasts for the incidence and mortality of mouth cancer are very grim. We hope more countries will develop their own oral cancer action campaigns to raise awareness." November is Mouth Cancer Action Month, sponsored annually by the IDHF.

Diagnosis for Michael Douglas highlights oral cancer risk

Source: www.dental-tribune.com Author: Fred Michmershuizen, DTA After it became known recently that the Academy Award winning actor Michael Douglas has been diagnosed with oral cancer, dental professionals around the world seized on an opportunity to urge members of the public to pay more attention to key risk factors and early warning signs of the disease. The Academy Award winner was diagnosed with a tumor in his throat, and he now faces an eight-week course of chemotherapy and radiotherapy. This high-profile case has brought oral cancers into the limelight, and oral health experts are keen to make the public more aware of the key risk factors and early warning signs. The British Dental Health Foundation is calling for more attention to be paid to mouth cancers. The foundation is advising the public to regularly check their mouths. Douglas quit smoking in 2006, after a long “half a pack a day” habit. Yet, according to the foundation, the possibility of developing oral cancer remains higher for ex-smokers than non-smokers for 20 years after quitting. Tobacco is considered to be the main cause of mouth cancer, with three in four cases being linked to smoking, according to the foundation. Drinking in excess is also a known factor, with those who both smoke and drink to excess being up 30 times more likely to be at risk. “It is crucial the public know about the risk factors and early symptoms as early detection can save lives,” said Dr. Nigel Carter, chief executive of the [...]
