Surgical tracheostomy in a patient with a stuck tracheal tube in situ.

The inability to extubate a patient's trachea due to a mechanical complication is rarely encountered in clinical practice. The risks of attempting to remove a stuck tracheal tube include laryngeal trauma, vocal cord injury and arytenoid dislocation, all of which have significant implications. Here, we report the case of a patient who was admitted to the intensive care unit for mechanical ventilation following liver transplant surgery. Her trachea was initially extubated on the second postoperative day, but she required further mechanical ventilation the following day and her trachea was re-intubated. Five days later, she was deemed suitable for tracheal extubation, but the formation of granulation tissue around the tracheal tube prevented its removal. A multi-disciplinary decision-making approach was taken when deciding to site a surgical tracheostomy. A flexible bronchoscope was used as an aid for safe placement. This facilitated safe extrication of the tracheal tube, which was freed by gentle manipulation both proximally and distally. We suspect that tracheal tube size may have been a factor in the development of the granulation tissue in this case. It is important to consider tracheal tube size in all patients, particularly if they require tracheal re-intubation or are likely to require mechanical ventilation for a prolonged period.

Surgery school-who, what, when, and how: results of a national survey of multidisciplinary teams delivering group preoperative education.

BACKGROUND: Group education is increasing in popularity as a means of preparing patients for surgery. In recent years, these 'surgery schools' have evolved from primarily informing patients of what to expect before and after surgery, to providing support and encouragement for patients to 'prehabilitate' prior to surgery, through improving physical fitness, nutrition and emotional wellbeing. METHOD: A survey aimed at clinicians delivering surgery schools was employed to capture a national overview of activity to establish research and practice priorities in this area. The survey was circulated online via the Enhanced Recovery after Surgery UK Society and the Centre for Perioperative Care mailing lists as well as social media. RESULTS: There were 80 responses describing 28 active and 4 planned surgery schools across the UK and Ireland. Schools were designed and delivered by multidisciplinary teams, contained broadly similar content and were well attended. Most were funded by the National Health Service. The majority included aspects of prehabilitation most commonly the importance of physical fitness. Seventy five percent of teams collected patient outcome data, but less than half collected data to establish the clinical effectiveness of the school. Few describe explicit inclusion of evidence-based behavior change techniques, but collaboration and partnerships with community teams, gyms and local charities were considered important in supporting patients to make changes in health behaviors prior to surgery. CONCLUSION: It is recommended that teams work with patients when designing surgery schools and use evidence-based behavior change frameworks and techniques to inform their content. There is a need for high-quality research studies to determine the clinical effectiveness of this type of education intervention.

A Prospective Cohort Study of Human Papillomavirus-Driven Oropharyngeal Cancers: Implications for Prognosis and Immunisation.

AIMS: Oropharyngeal cancer (OPC) is increasing on a global scale, including the component driven by high-risk human papillomavirus (HR-HPV); contemporary data that provides insight into the prognosis of this disease in addition to the fraction attributable to HR-HPV are essential to inform primary and secondary disease management strategies. MATERIALS AND METHODS: A population-based cohort of 235 patients diagnosed with OPC between 2013 and 2015 in Scotland was assessed for HPV status using molecular genotyping. Associations between HR-HPV status and key clinical and demographic variables were estimated using the Pearson chi-squared test. Rates of overall survival and progression-free survival were estimated and visualised using Kaplan-Meier curves. RESULTS: HPV DNA (largely HPV 16) was identified in 60% of cases. After adjustment for age, gender, deprivation, smoking, alcohol consumption and tumour stage, patients with HR-HPV-positive OPC had an 89% reduction in the risk of death (hazard ratio = 0.11, 95% confidence interval 0.05-0.25) and an 85% reduction in the risk of disease progression (hazard ratio = 0.15, 95% confidence interval 0.07-0.30). HPV positivity was not associated with age, deprivation or smoking status, whereas those who reported excess alcohol consumption were less likely to be positive for HR-HPV. CONCLUSIONS: The prevalence of HR-HPV-associated OPC is high in Scotland and strongly associated with dramatically improved clinical outcomes, including survival. Demographic/behavioural variables did not reliably predict HPV positivity in this cohort, which underlines the importance of laboratory confirmation. Finally, the dominance of HPV 16 in OPC indicates the significant impact of prophylactic immunisation on this disease.

Guidelines for the safe provision of anaesthesia in magnetic resonance units 2019: Guidelines from the Association of Anaesthetists and the Neuro Anaesthesia and Critical Care Society of Great Britain and Ireland.

There has been an increase in the number of units providing anaesthesia for magnetic resonance imaging and the strength of magnetic resonance scanners, as well as the number of interventions and operations performed within the magnetic resonance environment. More devices and implants are now magnetic resonance imaging conditional, allowing scans to be undertaken in patients for whom this was previously not possible. There has also been a revision in terminology relating to magnetic resonance safety of devices. These guidelines have been put together by organisations who are involved in the pathways for patients needing magnetic resonance imaging. They reinforce the safety aspects of providing anaesthesia in the magnetic resonance environment, from the multidisciplinary decision making process, the seniority of anaesthetist accompanying the patient, to training in the recognition of hazards of anaesthesia in the magnetic resonance environment. For many anaesthetists this is an unfamiliar site to give anaesthesia, often in a remote site. Hospitals should develop and audit governance procedures to ensure that anaesthetists of all grades are competent to deliver anaesthesia safely in this area.

The changing epidemiology of oral cancer: definitions, trends, and risk factors.

Objective: This review has three objectives, namely: (i) to discuss how oral cancer is and ought to be defined and recorded; (ii) to present up-to-date data on the incidence burden of the disease in the four countries of the UK, and review recent analyses of trends in the disease; and (iii) to summarise recent evidence on risk factors of the disease. Methods: Cancer definitions were clarified by the International Classification of Diseases accounting for anatomical and aetiological differences; descriptive epidemiology included international / UK literature review and information requests for incidence data from the UK cancer registries (2000-2016); analytical epidemiology focused on reviewing the findings of the International Head and Neck Cancer Epidemiology (INHANCE) consortium, which has pooled data from multiple case-control studies providing the best estimates of risk factors. Results: Emerging evidence of the role played by risk factors in different anatomical sites means that oral cavity cancer and oropharynx cancer should be considered distinct disease entities ­ and a standardised attribution of anatomical subsites will be helpful in ensuring consistency in how data are presented. In 2016, over 3,700 people were diagnosed with oral cavity cancer and over 3,500 people were diagnosed with oropharyngeal cancer in the UK. Incidence of oropharyngeal cancer is rapidly rising across the UK. Rates of oral cavity cancer are higher in Northern Ireland and higher still (and relatively stable) in Scotland, but rising in England and Wales. INHANCE data show that while the consumption of alcohol and tobacco are the prime risk factors for oral cavity and oropharyngeal cancers, they provide greater certainty in the preventive benefits of reducing these risk factors. The role played by other factors such as low socioeconomic status, genetics, oral health, and human papillomavirus (only for oropharyngeal cancer) have become clearer. Conclusions: This epidemiology provides a strong foundation for designing and managing both population and individual oral cavity and oropharyngeal cancer control strategies.

Is detecting oral cancer in general dental practices a realistic expectation? A population-based study using population linked data in Scotland.

Aims: To examine, for the first time on a population-basis via data linkage, whether early detection by general dental practices (GDP) is a realistic expectation by i) estimating the number of OC cases/year a dentist in Scotland may encounter over time, accounting for the deprivation level of practice location and dental registration/attendance rates, and ii) assessing whether patients attended GDPs two years pre-diagnosis. Materials and methods: Scottish Cancer Registry data on all OC cases (2010-2012), published NHS Scotland dental workforce and registration/participation statistics, and individual patient data linked with NHS dental service activity were analysed. Results: Dentists were estimated to potentially encounter one case of OC every 10 years, OCC every 16.7 years, and OPC every 25 years. However, 53.7% of OC patients had made no dental contact two years pre-diagnosis. Conclusion: Strategies for early detection must consider the rarity of OC incidence and poor dental attendance patterns. These results highlight the importance of improving access and uptake of dental services among those at highest risk to increase the opportunities for early detection.

Predictors of oropharyngeal cancer survival in Europe.

OBJECTIVES: HPV16-positive oropharyngeal cancer (OPC) patients experience better outcomes compared to HPV16-negative patients. Currently, strategies for treatment de-escalation are based on HPV status, smoking history and disease stage. However, the appropriate cut-point for smoking and the role of other non-clinical factors in OPC survival remains uncertain. MATERIALS AND METHODS: We examined factors associated with OPC outcome in 321 patients recruited in a large European multi-center study. Seropositivity for HPV16 E6 was used as a marker of HPV16 positive cancer. Hazard ratios (HR) and confidence intervals (CI) were estimated using Cox proportional models adjusted for potential confounders. RESULTS: Overall 5-year survival following OPC diagnosis was 50%. HPV16-positive OPC cases were at significantly lower risk of death (aHR = 0.51, 95% CI: 0.32-0.80). A significant effect on OPC survival was apparent for female sex (aHR 0.50: 95% CI: 0.29-0.85) and being underweight at diagnosis (aHR: 2.41, 95% CI: 1.38-4.21). A 10 pack year smoking history was not associated with overall survival. Higher stage at diagnosis appeared as the only factor significantly associated with OPC recurrence (aHR: 4.88, 95% CI: 2.12-11.21). CONCLUSION: This study confirms that HPV16 status is an independent prognostic factor for OPC survival while female sex lowers risk of death and being underweight at diagnosis increases the risk of death. Smoking was not an independent predictor of OPC survival.

Presenting symptoms and long-term survival in head and neck cancer.

OBJECTIVES: To assess how type and number of symptoms are related to survival in patients with head and neck cancer. DESIGN: Patients were followed up for over 10 years from the Scottish Audit of Head and Neck Cancer (national cohort of head and neck cancer patients in Scotland 1999-2001). September 2013, cohort was linked to national mortality data. First, second and third presenting symptoms were recorded at diagnosis. SETTING: National prospective audit-Scotland. PARTICIPANTS: A subset of 1589 patients, from the original cohort of 1895, who had cancer arising from one of the four main subsites; larynx, oropharynx, oral cavity and hypopharynx. MAIN OUTCOME MEASURES: Median survival in relation to patients' presenting symptoms. RESULTS: A total of 1146 (72%) males and 443 (28%) females, mean age at diagnosis 64 years (13-95). There was a significant difference in survival in relation to the number of the patient's presenting symptoms; one symptom had a median survival of 5.3 years compared with 1.1 years for three symptoms. Patients who presented with weight loss had a median survival of 0.8 years, compared to 4.2 years if they did not (P < .001). Patients who presented with hoarseness had a median survival of 5.9 years compared to 2.6 years without (P < .001). There was no significant difference in long-term survival for patients who presented with an ulcer, compared to those that did not (P = .105). CONCLUSIONS: This study highlights the importance of patients' presenting symptoms, giving valuable information in highlighting appropriate "red flag" symptoms and subsequent treatment planning and prognosis.

Impact of a peri-operative quality improvement programme on postoperative pulmonary complications.

Postoperative pulmonary complications are common, with a reported incidence of 2-40%, and are associated with adverse outcomes that include death, longer hospital stay and reduced long-term survival. Enhanced recovery is now a standard of care for patients undergoing elective major surgery. Despite the high prevalence of pulmonary complications in this population, few elements of enhanced recovery specifically address reducing these complications. In 2013, a prevalence audit confirmed a postoperative pulmonary complication rate of 16/83 (19.3%) in patients undergoing elective major surgery who were admitted to critical care postoperatively. A quality improvement team developed and implemented ERAS+, an innovative model of peri-operative care combining elements of enhanced recovery with specific measures aimed at reducing pulmonary complications. ERAS+ was introduced in June 2014, with full implementation in September 2014. Patients were screened during full ERAS+ implementation and again one year following implementation. Following ERAS+ implementation, postoperative pulmonary complications reduced to 24/228 (10.5%). Sustained improvement was evident one year after implementation, with a pulmonary complication rate of 16/183 (8.7%). Median (IQR [range]) length of hospital stay one year after implementation of ERAS+ also improved from 12 (9-15 [4-101]) to 9 (5.5-10.5 [3-81]) days. The ERAS+ pathway is applicable to patients undergoing elective major surgery and appears effective in reducing postoperative pulmonary complications.

Multi-centre field evaluation of the performance of the Trinity Biotech Uni-Gold HIV 1/2 rapid test as a first-line screening assay for gay and bisexual men compared with 4th generation laboratory immunoassays.

BACKGROUND: The Trinity Biotech Uni-Gold HIV test (Uni-Gold) is often used as a supplementary rapid test in testing algorithms. OBJECTIVE: To evaluate the operational performance of the Uni-Gold as a first-line screening test among gay and bisexual men (GBM) in a setting where 4th generation HIV laboratory assays are routinely used. STUDY DESIGN: We compared the performance of Uni-Gold with conventional HIV serology conducted in parallel among GBM attending 22 testing sites. Sensitivity was calculated separately for acute and established infection, defined using 4th generation screening Ag/Ab immunoassay (EIA) and Western blot results. Previous HIV testing history and results of supplementary 3rd generation HIV Ab EIA, and p24 antigen EIA were used to further characterise cases of acute infection. RESULTS: Of 10,793 specimens tested with Uni-Gold and conventional serology, 94 (0.90%, 95%CI:0.70-1.07) were confirmed as HIV-positive by conventional serology, and 37 (39.4%) were classified as acute infection. Uni-Gold sensitivity was 81.9% overall (77/94, 95%CI:72.6-89.1); 56.8% for acute infection (21/37, 95%CI:39.5-72.9) and 98.2% for established infection (56/57, 95%CI:90.6-100.0). Of 17 false non-reactive Uni-Gold results, 16 were acute infections, and of these seven were p24 antigen reactive but antibody negative. Uni-Gold specificity was 99.9% (10,692/10,699, 95%CI:99.9-100.0), PPV was 91.7% (95%CI:83.6-96.6) and NPV was 99.8% (95%CI:99.7-99.9), respectively. CONCLUSIONS: In this population, Uni-Gold had good specificity and sensitivity was high for established infections when compared to 4th generation laboratory assays, however sensitivity was lower in acute infections. Where rapid tests are used in populations with a high proportion of acute infections, additional testing strategies are needed to detect acute infections.

The potential role of dentists in HIV screening.

Recent evidence suggests there is a role for the dental team, particularly dentists, in offering chairside HIV screening to patients during dental appointments. HIV is no longer a death sentence with early diagnosis and effective treatment contributing to a good prognosis. Despite the availability of both venipuncture diagnostic and rapid saliva/finger prick screening tests for HIV infection, 25% of people living with HIV in the United Kingdom are undiagnosed and remain at risk of transmitting their infection if having unprotected sex. This paper highlights the international evidence that supports dentists' willingness to conduct HIV screening and dental patient acceptance, and explores whether this is an opportunity or a step too far.

Effect of testing experience and profession on provider acceptability of rapid HIV testing after implementation in public sexual health clinics in Sydney.

OBJECTIVES: Rapid HIV testing (RHT) is well established in many countries, but it is new in Australia since a policy change in 2011. We assessed service provider acceptability of RHT before and after its implementation in four Sydney public sexual health clinics. METHODS: Service providers were surveyed immediately after training in RHT and again 6-12 months later. Differences in mean scores between survey rounds were assessed via t-tests, with stratification by profession and the number of tests performed. RESULTS: RHT was rated as highly acceptable among staff at baseline and acceptability scores improved between survey rounds. Belief in being sufficiently skilled and experienced to perform RHT (P = 0.004) and confidence in the delivery of nonreactive results increased (P = 0.007), while the belief that RHT was disruptive declined (P = 0.001). Acceptability was higher for staff who had performed a greater number of tests regarding comfort with their role in RHT (P = 0.004) and belief that patients were satisfied with RHT (P = 0.007). Compared with nurses, doctors had a stronger preference for a faster rapid test (P = 0.027) and were more likely to agree that RHT interfered with consultations (P = 0.014). CONCLUSIONS: Differences in responses between professions may reflect differences in staff roles, the type of patients seen by staff and the model of testing used, all of which may affect the number of tests performed by staff. These findings may inform planning for how best to implement RHT in clinical services.

Role of medical history and medication use in the aetiology of upper aerodigestive tract cancers in Europe: the ARCAGE study.

BACKGROUND: The study aimed to investigate the role of medical history (skin warts, Candida albicans, herpetic lesions, heartburn, regurgitation) and medication use (for heartburn; for regurgitation; aspirin) in the aetiology of upper aerodigestive tract (UADT) cancer. METHODS: A multicentre (10 European countries) case-control study [Alcohol-Related CAncers and GEnetic susceptibility (ARCAGE) project]. RESULTS: There were 1779 cases of UADT cancer and 1993 controls. History of warts or C. albicans infection was associated with a reduced risk [odds ratio (OR) 0.80, 95% confidence interval (CI) 0.68-0.94 and OR 0.73, 95% CI 0.60-0.89, respectively] but there was no association with herpetic lesions, heartburn, regurgitation or medication for related symptoms. Regurgitation was associated with an increased risk for cancer of the oesophagus (OR 1.47, 95% CI 0.98-2.21). Regular aspirin use was not associated with risk of UADT cancer overall but was associated with a reduced risk for cancer of oesophagus (OR 0.51, 95% CI 0.28-0.96), hypopharynx (OR 0.53, 95% CI 0.28-1.02) and larynx (OR 0.74, 95% CI 0.54-1.01). CONCLUSIONS: A history of some infections appears to be a marker for decreased risk of UADT cancer. The role of medical history and medication use varied by UADT subsites with aspirin use associated with a decreased risk of oesophageal cancer and suggestive of a decreased risk of hypopharyngeal and laryngeal cancers.

Life course social mobility and risk of upper aerodigestive tract cancer in men.

The aim of this study was to explore associations between social mobility and tumours of the upper aero-digestive tract (UADT), focussing on life-course transitions in social prestige (SP) based on occupational history. 1,796 cases diagnosed between 1993 and 2005 in ten European countries were compared with 1585 controls. SP was classified by the Standard International Occupational Prestige Scale (SIOPS) based on job histories. SIOPS was categorised in high (H), medium (M) and low (L). Time weighted average achieved and transitions between SP with nine trajectories: H --> H, H --> M, H --> L, M --> H, M --> M, M --> L, L --> H, L --> M and L --> L were analysed. Odds ratios (ORs) and 95%-confidence intervals [95%-CIs] were estimated with logistic regression models including age, consumption of fruits/vegetables, study centre, smoking and alcohol consumption. The adjusted OR for the lowest versus the highest of three categories (time weighted average of SP) was 1.28 [1.04-1.56]. The distance of SP widened between cases and controls during working life. The downward trajectory H --> L gave an OR of 1.71 [0.75-3.87] as compared to H --> H. Subjects with M --> M and L --> L trajectories ORs were also elevated relative to subjects with H --> H trajectories. The association between SP and UADT is not fully explained by confounding factors. Downward social trajectory during the life course may be an independent risk factor for UADT cancers.

Socioeconomic factors associated with risk of upper aerodigestive tract cancer in Europe.

INTRODUCTION: In the European Union, there are 180,000 new cases of upper aerodigestive tract (UADT) cancer cases per year--more than half of whom will die of the disease. Socioeconomic inequalities in UADT cancer incidence are recognised across Europe. We aimed to assess the components of socioeconomic risk both independently and through their influence on the known behavioural risk factors of smoking, alcohol consumption and diet. PATIENTS AND METHODS: A multicentre case-control study with 2198 cases of UADT cancer and 2141 controls from hospital and population sources was undertaken involving 14 centres from 10 countries. Personal interviews collected information on demographics, lifetime occupation history, smoking, alcohol consumption and diet. Socioeconomic status was measured by education, occupational social class and unemployment. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed using unconditional logistic regression. RESULTS: When controlling for age, sex and centre significantly increased risks for UADT cancer were observed for those with low versus high educational attainment OR=1.98 (95% CI 1.67, 2.36). Similarly, for occupational socioeconomic indicators--comparing the lowest versus highest International Socio-Economic Index (ISEI) quartile for the longest occupation gave OR=1.60 (1.28, 2.00); and for unemployment OR=1.64 (1.24, 2.17). Statistical significance remained for low education when adjusting for smoking, alcohol and diet behaviours OR=1.29 (1.06, 1.57) in the multivariate analysis. Inequalities were observed only among men but not among women and were greater among those in the British Isles and Eastern European countries than in Southern and Central/Northern European countries. Associations were broadly consistent for subsite and source of controls (hospital and community). CONCLUSION: Socioeconomic inequalities for UADT cancers are only observed among men and are not totally explained by smoking, alcohol drinking and diet.

Pattern analysis of microtubule-polymerizing and -depolymerizing agent combinations as cancer chemotherapies.

Subcellular distribution of mass can be analyzed by a technique that involves culturing cells on interferometers and digitizing their interference contours. Contour sampling resulted in 102 variables per cell, which were predictors of oncogenic transformation. Cell phenotypes can be deconstructed by use of latent factors, which represent the covariance of the real variables. The reversal of the cancer-type phenotype by a combination of microtubule-stabilizing and -depolymerizing agents was described previously. The implications of these results have been explored by clinicians who treated patients with the combination of docetaxel and vinorelbine (Navelbine). The current study was performed to determine the effects of different combinations on phenotype and in phases of the cell cycle other than mitosis. Combinations of paclitaxel with either colchicine, podophyllotoxin, nocodazole, or vinblastine caused phenotype reversal. Paclitaxel analogue, 7-deoxytaxol, by itself caused reversal. Factors #4, (filopodia), #5 (displacement and/or deep invaginations in the periphery), #8, and #12 took on values typical of normal cells, whereas the values of #7 (p21-activated kinase), and #13 (rounding up) shifted toward the cancer-type. All combinations altered microtubule arrangement at the cell edge. Delivery schedules and drug ratios used in clinical studies were subjected to analysis. Clinical response rates were better when the combination was not interspersed with a single agent (P=0.004). The results support the idea that efficacy depends upon simultaneous exposure to both agents, and suggest a novel mechanism for combination therapies. These therapies appear to restore in transformed cells some of the features of a contact-inhibited cell, and to impede progress through the cell cycle even when provided at nanomolar concentrations.

Interventions for the treatment of oral and oropharyngeal cancers: surgical treatment.

BACKGROUND: Oral and oropharyngeal cancers can be managed by surgery alone or with any combination of radiotherapy, chemotherapy and immunotherapy/biotherapy. Opinions on the surgical treatment, the optimal combinational therapy and the sequence of treatments in combinational therapy varies enormously. OBJECTIVES: To determine which surgical treatment modalities for oral and oropharyngeal cancers lead to the best outcomes compared with other surgical, radiotherapy, chemotherapy or immunotherapy/biotherapy combinations. SEARCH STRATEGY: Electronic search of the Cochrane Oral Health Group Trials Register, CENTRAL, MEDLINE, OLDMEDLINE, EMBASE, AMED and the National Cancer Trials Database. Reference lists from relevant articles were searched and the authors of eligible trials were contacted. Date of the most recent searches: July 2007. SELECTION CRITERIA: Randomised controlled trials of surgery alone or in combination with chemotherapy, radiotherapy or immunotherapy/biotherapy for the treatment of primary oral or oropharyngeal cancer or both. DATA COLLECTION AND ANALYSIS: A minimum of two review authors conducted data extraction. Risk ratios were calculated for dichotomous outcomes at different time intervals, and hazard ratios were extracted or calculated for disease-free survival, total mortality, and disease-related mortality. Additional information from trial authors was sought. Data on adverse events were collected from the trial reports. MAIN RESULTS: Thirty-one trials satisfied the inclusion criteria, only 13 of which were assessed as low risk of bias. Trials were grouped into 12 main comparisons. There were no trials that compared different surgical modalities of the primary tumour itself. However, there were a number of trials comparing different approaches to managing the cervical lymph nodes. The majority of treatment regimens under evaluation were surgery in combination with other modalities. As individual treatment regimens within each comparison varied, meta-analysis was inappropriate in most instances. Only two trials could be pooled, comparing concomitant radio/chemotherapy (with surgery) versus radiotherapy (with surgery). A statistically significant difference was shown for disease-free survival (hazard ratio 0.77, 95% confidence interval (CI): 0.64 to 0.92) and total mortality (hazard ratio 0.78, 95% CI: 0.64 to 0.95) in favour of the concomitant chemotherapy and radiotherapy (with surgery) arm. No other treatment regimens showed consistent statistically significant results across the outcomes measured. AUTHORS' CONCLUSIONS: There is some evidence that concomitant radio/chemotherapy (with surgery) is more effective than radiotherapy (with surgery) and may benefit outcomes in patients with more advanced oral and oropharyngeal cancers. As these trials were based on head and neck studies, future studies should evaluate this treatment regimen specifically in oral and oropharyngeal cancers separately and also address tumour staging and its impact on outcomes. In general, future studies are encouraged to evaluate site-specific and stage-specific data for oral and oropharyngeal cancers. Future trials should include health-related quality of life assessment as an outcome measure. There is a need for a consolidated standardised approach to reporting adverse events.

Characteristics of patients attending rapid access clinics during the West of Scotland Cancer Awareness Programme oral cancer campaign.

AIM: In 2003, the West of Scotland Cancer Awareness Programme (WoSCAP) launched their oral cancer campaign to raise public awareness of the disease in five NHS boards across the West of Scotland. The aim of this study was to evaluate the campaign by reviewing patients attending rapid access clinics in the 11 secondary care units across the five boards. DESIGN: Data were collected in 2004 during the second phase of the campaign via a two part self-completing questionnaire; the first part collected information from the patients and the second part from the clinicians, in rapid access clinics in the secondary care units. RESULTS: In total, 580 questionnaires were given out in the clinics with 538 completed patient sections (response rate 93%) and 500 completed clinician sections (response rate of 86%). More than two thirds of rapid access secondary care patients had seen a recent health campaign related to mouth cancer, and 46% responded that the campaign had encouraged them to seek advice more quickly. Of the patients examined in the clinics, 5% had a provisional diagnosis of a malignant lesion, 7% a potentially malignant lesion, and the majority of lesions were benign. The clinicians deemed 30% of the referrals to be inappropriate. CONCLUSIONS: The results show a high percentage of patients attending rapid access clinics were aware of the campaign. However, there were a disproportionate number of inappropriate referrals to the rapid access clinics compared to genuinely urgent cases.

Widening socio-economic inequalities in oral cancer incidence in Scotland, 1976-2002.

Oral cancer incidence was investigated among 10 857 individuals using Scottish Cancer Registry data. Since 1980 the incidence of oral cancer among males in Scotland has significantly increased, the rise occurring almost entirely in the most deprived areas of residence.

Incidence of oral and oropharyngeal cancer in United Kingdom (1990-1999) -- recent trends and regional variation.

This study aimed to determine whether the incidence of oral cancer is continuing to rise in the UK and if this varies geographically. A descriptive epidemiological study of oral cancer incidence in 12 UK cancer registries (1990-1999) was undertaken. Poisson regression models were employed to assess trends. There were 32,852 oral cancer cases registered (1990-1999). Statistically significant increases in incidence of 18% and 30% were seen in males and females respectively (p<0.01). The trend was observed in younger (<45 years) and older (45+ years) age groups (p<0.01) with 3.5% and 2.4% average annual increases respectively. These increases were consistent for the majority of regions in the older group. For the younger group the increases in incidence were more rapid and differed geographically. Incidence remains higher in men than women, in older compared with younger groups, and in northern regions. These findings provide evidence of a continuing increase in the burden of oral cancer across the UK.
