Risk factors for squamous cell carcinoma of the oral cavity in young people — a comprehensive literature review

Carrie Llewellyn; Newell Walter Johnson; K. A. A. S. Warnakulasuriya

There have been several reports of a rising incidence of oral cancer from many parts of the world. Although it is well known that oral cancer increases with age, recent trends for a rising incidence particularly relates to cancer of the tongue and mouth in young males. This review critically examines 46 publications devoted to oral cancer in the young adult. Most studies suggest that 4-6% of oral cancers now occur at ages younger than 40 years. Several studies examining risk factors for oral cancer in the young provide evidence that many younger patients have never smoked or consumed alcohol, which are recognised risk factors in older groups, or that duration of exposure may be too short for malignant transformation to occur. Information on many aspects of aetiology for this disease in the young implicating occupational, familial risk, immune deficits and virus infection are meagre. The spectrum of genetic abnormality disclosed is similar to older patients, there is paucity of specific studies involving younger cohorts, but predisposition to genetic instability has been hypothesised as a likely cause. Conflicting evidence is also reported on the sex distribution and outcome compared with older patients. Much work is required to understand the caveats related to global demography, risk factors and their diagnostic and prognostic markers for this disease which might be considered a disease distinct from that occurring in older patients.

Background: there is, currently, much anecdotal and some epidemiological evidence for a rise in oral cancer rates amongst younger individuals, many of whom have had no exposure to traditional risk factors such as tobacco and heavy alcohol use, or at least not the exposure over decades usually associated with this disease. The probity of this assertion and the presence or absence of traditional risk factors needs further evidence. Objectives: this paper describes the demography and the exposure to potential risk factors amongst a cohort aged 45 years and younger, diagnosed with squamous cell carcinoma of the oral cavity between 1990 and 1997 from the South East of England. Materials and methods: eligible patients registered with a cancer registry were included in this retrospective study. Information was accessed from the database and by a postal questionnaire survey. The self-completed questionnaire contained items about exposure to the following risk factors: tobacco; alcohol; diet; frequency of dental visits and familial cancer. Results and conclusions: this is the largest UK epidemiological study so far to be undertaken on young subjects diagnosed with oral cancer. One-hundred and sixteen cases were recruited representing a response rate of 59%. Slightly over 90% of this cohort were classified as white European. A large proportion of cases (40%) were from social classes I & II suggesting either a true social class difference in young cases versus older oral cancer cases or a possible bias in responders or survivors. Risk factors of tobacco use and excessive alcohol consumption were present in the majority (75%) of patients. Significant differences in the pattern of alcohol consumption were found in female subjects, who were less likely to consume over the recommended amounts of alcohol compared with male subjects. Daily regular fresh fruit and vegetable consumption during the ten year period before cancer diagnosis was recorded to be low. There was a distinct subgroup of cases, 26% of the group, that showed little, if any, exposure to any major risk factors.

OBJECTIVES The objectives of this study were to investigate longitudinal predictors of fear of recurrence in survivors of head and neck cancer (HNC) using Leventhals Common Sense Model (CSM) as a framework. The research questions were as follows: (a) to what extent do HNC patients report fear of cancer recurrence? (b) To what extent are fears of recurrence manifestations of illness-related anxiety? (c) Are fears of recurrence closely related to current symptoms, disease, and treatment-related factors, or psychological/socio-demographic factors? (d) What factors are predictive of long-term fears of recurrence? METHODS A prospective repeat measures design was employed whereby a sample of 82 newly diagnosed HNC patients (54 males, 28 females, mean age 60 years) completed measures of fears of recurrence, illness perceptions, coping, and anxiety and depression, prior to treatment and 6-8 months after treatment (fears of recurrence only). RESULTS A third of HNC patients at diagnosis reported relatively high levels of fears of recurrence, with 12% still reporting similar levels of fear 6-8 months after treatment. Fears of recurrence were not related to any socio-demographic factor (age, gender, ethnicity, marital status, and educational attainment) or disease, treatment, or symptom-related factors. Path analyses demonstrated that fears of cancer recurrence after treatment were directly predicted by pre-treatment fears and optimism. CONCLUSION Although components of the CSM (cognitive and emotional representations, coping strategies) were associated with fears of recurrence, optimism was found to be the strongest predictor of fear, independent of anxiety and level of fear reported prior to treatment.

Introduction: Self-taken specimens from men who have sex with men (MSM) could be important in reducing high levels of demand on sexual health services. The performance of self-taken specimens for the detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) from both pharyngeal and rectal sites in asymptomatic MSM was assessed. Methods: MSM were examined according to clinic protocol: a rectal and pharyngeal swab for GC culture and a rectal swab for the CT strand displacement assay. An extra set of nurse-taken and self-taken pharyngeal and rectal specimens were also requested and were tested using the Aptima Combo 2 assay and the result compared with the routine clinic result, which was considered the gold standard. Results: A total of 272 MSM was recruited and the sensitivity and specificity of nurse-taken and patient-taken swabs, respectively, was as follows: rectal GC: 94.9% and 90.1% (nurse); 92.3% and 87.9% (patient); pharyngeal GC: 88.2% and 91.8% (nurse); 100% and 87.8% (patient); rectal CT: 80.0% and 99.6% (nurse); 91.4% and 98.2% (patient). No significant difference in sensitivity or specificity was observed between the nurse-taken and the patient-taken rectal swabs for either GC or CT. For the detection of GC from the pharynx, comparable sensitivities were achieved between nurse-taken and patient-taken swabs (p = 0.5); however, a significant difference in specificity was observed (p = 0.006). This was due to a higher number of false GC-positive self-taken pharyngeal swabs from patients with high rates (90.9%; 10/11) of confirmed concurrent GC infection in different anatomical sites. Conclusions: MSM are able to collect self-taken rectal and pharyngeal swabs that are comparable to those taken by clinicians.

Associations between quality of life, coping styles, optimism, and anxiety and depression in pretreatment patients with head and neck cancer

Debbie J. Horney; Helen Smith; Mark McGurk; John Weinman; Jim Herold; Keith Altman; Carrie Llewellyn

Head and neck cancer is often diagnosed at a late stage and consequently radical treatment is necessary. The pretreatment phase is a time of high anxiety and depression for patients. This study aimed to investigate whether anxiety and depression are related to quality of life, coping styles, and dispositional optimism.

Some individuals are able to gain psychological benefits from illness and adversity, such as a greater sense of purpose and closer relationships, termed ‘benefit finding’ (BF). The main aim of this study was to explore the extent to which BF is reported in patients with head and neck cancer (HNC). Secondary aims were to establish the relationships between BF, other patient‐reported outcomes and predictive factors such as coping strategy and level of optimism.

Evaluating the effectiveness of health belief model interventions in improving adherence: a systematic review

Christina Jones; Helen Smith; Carrie Llewellyn

Lack of adherence to health-promoting advice challenges the successful prevention and management of many conditions. The Health Belief Model (HBM) was developed in 1966 to predict health-promoting behaviour and has been used in patients with wide variety of disease. The HBM has also been used to inform the development of interventions to improve health behaviours. Several reviews have documented the HBMs performance in predicting behaviour, but no review has addressed its utility in the design of interventions or the efficacy of these interventions. A systematic review was conducted to identify interventional studies which use the HBM as the theoretical basis for intervention design. The HBM has been used continuously in the development of behaviour change interventions for 40 years. Of 18 eligible studies, 14 (78%) reported significant improvements in adherence, with 7 (39%) showing moderate to large effects. However, only six studies used the HBM in its entirety and five different studies measured health beliefs as outcomes. Intervention success appeared to be unrelated to HBM construct addressed challenging the utility of this model as the theoretical basis for adherence-enhancing interventions. Interventions need to be described in full to allow for the identification of effective components and replication of studies.

Human papillomavirus and vaccine-related perceptions among men who have sex with men: a systematic review

Tom Nadarzynski; Helen Smith; Daniel Richardson; Christina Jones; Carrie Llewellyn

Background Targeted human papillomavirus (HPV) vaccine could prevent HPV-related cancers and genital warts among men who have sex with men (MSM). In order to develop effective vaccination programmes for MSM, it is crucial to understand their knowledge, beliefs about HPV and attitudes towards HPV vaccine. Methods A systematic search of 10 databases examined articles investigating HPV knowledge and HPV-related perceptions among MSM. Each paper was assessed to identify potential research directions in the context of targeted HPV vaccination for MSM. Results We identified 16 studies that included 5185 MSM and conducted mainly in North America. Generally, participants were over 26 years old, had poor-to-moderate knowledge about HPV and were not concerned about HPV-related diseases. Over a half of MSM were willing to accept HPV vaccine, if offered. However, there was large variability in HPV vaccine acceptability, partially due to inconsistencies in methods of ascertainment but also different levels of HPV vaccine awareness. Conclusions Despite several misconceptions and poor knowledge of HPV infection, MSM might be receptive to HPV vaccination. However, further research is needed to identify which factors contribute to potential vaccine uptake in hypothetical MSM-targeted HPV vaccination. Future studies need to target those MSM with little sexual experience, who would benefit most from HPV vaccination.

Self-sampling for oropharyngeal and rectal specimens to screen for sexually transmitted infections: acceptability among men who have sex with men

Sonali Wayal; Carrie Llewellyn; Helen Smith; Matthew Hankins; Alan Phillips; Daniel Richardson; Martin Fisher

Objectives: To explore the feasibility and acceptability of self-sampling for oropharyngeal and rectal specimens to screen for sexually transmitted infections (STIs) among men who have sex with men (MSM). Participant’s willingness to self-sample at home was also explored. Methods: Participants of a study to evaluate the sensitivity and specificity of self versus nurse taken oropharyngeal and rectal specimens were surveyed to assess the feasibility and acceptability of self-sampling using specimen collection methods (gargle, OraSure mouth pad to collect oropharyngeal specimens and APTIMA unisex swabs to collect rectal and pharyngeal specimens). Acceptability was measured using a five-point Likert-type response scale (for example, 1 =  strongly disagree; 5 =  strongly agree). Open-ended questions explored participants’ experiences of self-sampling. Results: Of 334 eligible MSM, 301 (90%) participated in the study. Altogether, 301 participants self-sampled using gargle and rectal and pharyngeal swabs and 288 using mouth pad. Complete questionnaire data from 274 participants showed that feasibility and acceptability of self-sampling using gargle and mouth pad was higher (92%) than pharyngeal swabs (76%). Rectal swabs were acceptable to 82% participants. Despite some discomfort and difficulty in using swabs, 76% were willing to use all four methods for self-sampling in the future. Home sampling was acceptable (84%) as it was perceived to be less intrusive and more convenient than a clinic visit and likely to reduce genitourinary medicine (GUM) waiting time. Conclusions: Self-sampling for rectal and oropharyngeal specimens is feasible and acceptable to MSM. Self-sampling can be offered as an alternative to clinic-based testing and has the potential to improve choice, access and uptake of screening for STIs.
