Head and neck cancer—Part 1: Epidemiology, presentation, and prevention
TL;DR: The common presentations of head and neck cancer is reviewed, which are important for functions such as speech, swallowing, taste, and smell, and potential functional and quality of life outcomes.
Abstract: #### Summary points
Head and neck cancers include cancers of the upper aerodigestive tract (including the oral cavity, nasopharynx, oropharynx, hypopharynx, and larynx), the paranasal sinuses, and the salivary glands. Cancers at different sites have different courses and variable histopathological types, although squamous cell carcinoma is by far the most common. The anatomical sites affected are important for functions such as speech, swallowing, taste, and smell, so the cancers and their treatments may have considerable functional sequelae with subsequent impairment of quality of life. Decisions about treatment are usually complex, and they must balance efficacy of treatment and likelihood of survival, with potential functional and quality of life outcomes. Patients and their carers need considerable support during and after treatment.
#### Sources and selection criteria
We used the terms “head and neck”, “larynx”, “oral”, and “oropharynx”—with each limited by “cancer”, “diagnosis”, and “treatment” separately—to search the Medline, Embase, PubMed, Cochrane, CINAHL, and AMED databases. We also used them to cross check national guidelines, reference lists, textbooks, and personal reference lists. We assessed over 1000 identified abstracts for relevance.
In this first part of a two article series, we review the common presentations of head and neck cancer. We also discuss common investigations and new …

...HNC defines a heterogeneous group of malignancies including those of the lip, oral cavity, nose and paranasal sinuses, nasopharynx, oropharynx, hypopharynx and larynx(3); the majority of which (85%) are of squamous cell carcinoma histology (HNSCC).(4) Since the 1970s the incidence rates of some oropharyngeal cancers (OPSCCs), particularly those of the tongue base and tonsil, have risen steadily in the USA and Northern Europe especially in younger patients without recognised HNC risk factors, suggesting alternate aetiological pathways....

TL;DR: To summarise patients' experiences of head and neck cancer (HNC) by examining the findings of existing qualitative studies, the authors suggest that the current standard of care for HNC patients is inadequate.
Abstract: Objective: To summarise patients' experiences of head and neck cancer (HNC) by examining the findings of existing qualitative studies Methods: We undertook a systematic review and meta-synthesis of qualitative studies in 29 published articles using Noblit and Hare's ‘meta-ethnography’ approach to synthesise findings. The inclusion criteria were primary qualitative studies, focusing on HNC patients' experience and an English abstract. Seven databases were systematically searched. Results: The articles focused on the experience of having HNC, the experience of treatments and the role of information. Our synthesis identified six core concepts—uncertainty and waiting, disruption to daily life, the diminished self, making sense of the experience, sharing the burden and finding a path. People experienced significant disruption to normal daily activities, because of the physical and emotional effects of HNC and its treatment. Day-to-day challenges were compounded by social and existential changes and a palpable loss of the individual's sense of self and future. In order to find a way through the considerable uncertainty and daily challenge of living with and beyond HNC, patients made continual efforts to make sense of their experience. Supportive relationships with their social network, HNC peers and healthcare professionals were particularly important, but support following treatment completion was sometimes limited. Perceptions of the future were affected by whether they saw life as diminished, merely changed or even enhanced by the experience of cancer. Conclusions: This review supports further specific research into these emerging themes and provides a context for future work, informing interventions to improve patients' experiences.

TL;DR: This study examined the risk of suicide across cancer sites, with a focus on survivors of head and neck cancer (HNC), and found that cancer survivors face psychosocial issues that increase their risk ofsuicide.
Abstract: Background Cancer survivors face psychosocial issues that increase their risk of suicide. This study examined the risk of suicide across cancer sites, with a focus on survivors of head and neck cancer (HNC). Methods The Surveillance, Epidemiology, and End Results 18-registry database (from 2000 to 2014) was queried for the top 20 cancer sites in the database, including HNC. The outcome of interest was suicide as a cause of death. The mortality rate from suicide was estimated for HNC sites and was compared with rates for 19 other cancer sites that were included in the study. Poisson regression was used to estimate adjusted rate ratios (aRRs) and 95% confidence intervals (CIs) for 1) HNC versus non-HNC sites (the other 19 cancer sites combined), and 2) HNC versus each individual cancer site. Models were stratified by sex, controlling for race, marital status, age, year, and stage at diagnosis. Results There were 404 suicides among 151,167 HNC survivors from 2000 to 2014, yielding a suicide rate of 63.4 suicides per 100,000 person-years. In this timeframe, there were 4493 suicides observed among 4219,097 cancer survivors in the study sample, yielding an incidence rate of 23.6 suicides per 100,000 person-years. Compared with survivors of other cancers, survivors of HNC were almost 2 times more likely to die from suicide (aRR, 1.97; 95% CI, 1.77-2.19). There was a 27% increase in the risk of suicide among HNC survivors during the period from 2010 to 2014 (aRR, 1.27; 95% CI, 1.16-1.38) compared with the period from 2000 to 2004. Conclusions Although survival rates in cancer have improved because of improved treatments, the risk of death by suicide remains a problem for cancer survivors, particularly those with HNC.

TL;DR: This timely monograph is a distillation of knowledge of hepatitis B, C and D, based on a review of 1000 studies by a small group of scientists, and it is concluded that hepatitis D virus cannot be classified as a human carcinogen.
Abstract: Viral hepatitis in all its forms is a major public health problem throughout the world, affecting several hundreds of millions of people. Viral hepatitis is a cause of considerable morbidity and mortality both from acute infection and chronic sequelae which include, in the case of hepatitis B, C and D, chronic active hepatitis and cirrhosis. Hepatocellular carcinoma, which is one of the 10 commonest cancers worldwide, is closely associated with hepatitis B and, at least in some regions of the world, with hepatitis C virus. This timely monograph is a distillation of knowledge of hepatitis B, C and D, based on a review of 1000 studies by a small group of scientists. (It is interesting to note in passing that some 5000 papers on viral hepatitis are published annually in the world literature.) The epidemiological, clinical and experimental data on the association between infection with hepatitis B virus and primary liver cancer in humans are reviewed in a readable and succinct format. The available information on hepatitis C and progression to chronic infection is also evaluated and it is concluded (perhaps a little prematurely) that hepatitis C virus is carcinogenic. However, it is concluded that hepatitis D virus, an unusual virus with a number of similarities to certain plant viral satellites and viroids, cannot be classified as a human carcinogen. There are some minor criticisms: there are few illustrations and some complex tabulations (for example, Table 6) and no subject index. A cumulative cross index to IARC Monographs is of little value and occupies nearly 30 pages. This small volume is a useful addition to the overwhelming literature on viral hepatitis, and the presentation is similar to the excellent World Health Organisation Technical Reports series on the subject published in the past. It is strongly recommended as a readable up-to-date summary of a complex subject; and at a cost of 65 Sw.fr (approximately £34) is excellent value. A J ZUCKERMAN

TL;DR: These projections represent a set of three visions of the future for population health, based on certain explicit assumptions, which enable us to appreciate better the implications for health and health policy of currently observed trends, and the likely impact of fairly certain future trends.
Abstract: Background Global and regional projections of mortality and burden of disease by cause for the years 2000, 2010, and 2030 were published by Murray and Lopez in 1996 as part of the Global Burden of Disease project. These projections, which are based on 1990 data, continue to be widely quoted, although they are substantially outdated; in particular, they substantially underestimated the spread of HIV/AIDS. To address the widespread demand for information on likely future trends in global health, and thereby to support international health policy and priority setting, we have prepared new projections of mortality and burden of disease to 2030 starting from World Health Organization estimates of mortality and burden of disease for 2002. This paper describes the methods, assumptions, input data, and results. Methods and Findings Relatively simple models were used to project future health trends under three scenarios—baseline, optimistic, and pessimistic—based largely on projections of economic and social development, and using the historically observed relationships of these with cause-specific mortality rates. Data inputs have been updated to take account of the greater availability of death registration data and the latest available projections for HIV/AIDS, income, human capital, tobacco smoking, body mass index, and other inputs. In all three scenarios there is a dramatic shift in the distribution of deaths from younger to older ages and from communicable, maternal, perinatal, and nutritional causes to noncommunicable disease causes. The risk of death for children younger than 5 y is projected to fall by nearly 50% in the baseline scenario between 2002 and 2030. The proportion of deaths due to noncommunicable disease is projected to rise from 59% in 2002 to 69% in 2030. Global HIV/AIDS deaths are projected to rise from 2.8 million in 2002 to 6.5 million in 2030 under the baseline scenario, which assumes coverage with antiretroviral drugs reaches 80% by 2012. Under the optimistic scenario, which also assumes increased prevention activity, HIV/AIDS deaths are projected to drop to 3.7 million in 2030. Total tobacco-attributable deaths are projected to rise from 5.4 million in 2005 to 6.4 million in 2015 and 8.3 million in 2030 under our baseline scenario. Tobacco is projected to kill 50% more people in 2015 than HIV/AIDS, and to be responsible for 10% of all deaths globally. The three leading causes of burden of disease in 2030 are projected to include HIV/AIDS, unipolar depressive disorders, and ischaemic heart disease in the baseline and pessimistic scenarios. Road traffic accidents are the fourth leading cause in the baseline scenario, and the third leading cause ahead of ischaemic heart disease in the optimistic scenario. Under the baseline scenario, HIV/AIDS becomes the leading cause of burden of disease in middle- and low-income countries by 2015. Conclusions These projections represent a set of three visions of the future for population health, based on certain explicit assumptions. Despite the wide uncertainty ranges around future projections, they enable us to appreciate better the implications for health and health policy of currently observed trends, and the likely impact of fairly certain future trends, such as the ageing of the population, the continued spread of HIV/AIDS in many regions, and the continuation of the epidemiological transition in developing countries. The results depend strongly on the assumption that future mortality trends in poor countries will have a relationship to economic and social development similar to those that have occurred in the higher-income countries.

TL;DR: The results represent the most precise estimates available of the independent association of each of the two main risk factors of head and neck cancer, and they exemplify the strengths of large-scale consortia in cancer epidemiology.
Abstract: Background At least 75% of head and neck cancers are attributable to a combination of cigarette smoking and alcohol drinking. A precise understanding of the independent association of each of these factors in the absence of the other with the risk of head and neck cancer is needed to elucidate mechanisms of head and neck carcinogenesis and to assess the efficacy of interventions aimed at controlling either risk factor. Methods We examined the extent to which head and neck cancer is associated with cigarette smoking among never drinkers and with alcohol drinking among never users of tobacco. We pooled individual-level data from 15 case – control studies that included 10 244 head and neck cancer case subjects and 15 227 control subjects, of whom 1072 case subjects and 5775 control subjects were never users of tobacco and 1598 case subjects and 4051 control subjects were never drinkers of alcohol. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional logistic regression models. All statistical tests were two-sided. Results Among never drinkers, cigarette smoking was associated with an increased risk of head and neck cancer (OR for ever versus never smoking = 2.13, 95% CI = 1.52 to 2.98), and there were clear dose – response relationships for the frequency, duration, and number of pack-years of cigarette smoking. Approximately 24% (95% CI = 16% to 31%) of head and neck cancer cases among nondrinkers in this study would have been prevented if these individuals had not smoked cigarettes. Among never users of tobacco, alcohol consumption was associated with an increased risk of head and neck cancer only when alcohol was consumed at high frequency (OR for three or more drinks per day versus never drinking = 2.04, 95% CI = 1.29 to 3.21). The association with high-frequency alcohol intake was limited to cancers of the oropharynx/hypopharynx and larynx. Conclusions Our results represent the most precise estimates available of the independent association of each of the two main risk factors of head and neck cancer, and they exemplify the strengths of large-scale consortia in cancer epidemiology.

TL;DR: The incidence of HPV‐positive cancers is still increasing in the County of Stockholm, suggesting an epidemic of a virus‐induced carcinoma, with soon practically all tonsillar SCC being HPV positive, as in cervical cancer.
Abstract: In the county of Stockholm, between 1970 and 2002, we have previously reported a 3-fold parallel increase in the incidence of tonsillar squamous cell carcinoma (SCC) and the proportion of human papillomavirus (HPV) positive tonsillar SCC. Here, we have followed the above parameters in all patients (n = 120) diagnosed with tonsillar SCC during 2003-2007 in the same area, and also in correlation to our previous data. Ninety-eight pretreatment biopsies were available and presence of HPV DNA and HPV-16 E6 and E7 RNA were tested by polymerase chain reaction (PCR) and RT-PCR. Incidence data were obtained from the Swedish Cancer Registry. Data reported from 1970 to 2002 were also obtained for comparison. HPV DNA was present in 83 of 98 (85%) of the tonsillar SCC biopsies from 2003 to 2007 and 77 of these were HPV-16 positive. HPV-16 E6 and E7 RNA were found in 98% of 52 analyzed HPV-16 positive cases. The proportion of HPV-positive cancers had significantly increased both from 1970 to 2007 (p < 0.0001) as well from 2000 to 2007 (p < 0.01), with 68% (95% confidence interval (CI), 53-81) 2000-2002; 77% (95% CI, 63-87) 2003-2005; and 93% (95% CI, 82-99) 2006-2007. The incidence rate of HPV-positive tumors almost doubled each decade between 1970 and 2007, in parallel with a decline of HPV-negative tumors. In conclusion, the incidence of HPV-positive cancers is still increasing in the County of Stockholm, suggesting an epidemic of a virus-induced carcinoma, with soon practically all tonsillar SCC being HPV positive, as in cervical cancer.
