Social inequalities in oral cancer literacy in an adult population in a multicultural deprived area of the UK

The UK public and healthcare professionals' awareness of mouth cancer

As the rate of new mouth cancer diagnoses continues to increase in the UK, awareness of risk factors and signs and symptoms remains low. This paper focuses on studies showing UK public awareness of risk factors, including alcohol, tobacco and human papillomavirus, as well as public understanding of signs and symptoms of mouth cancer. It includes a review of the effectiveness of campaigns in raising awareness of mouth cancer and examples of campaigns targeting other common cancers or risk factors that may provide useful learning ahead of upcoming mouth cancer campaigns. In addition, the awareness of the wider healthcare team and the importance of their role in identifying mouth cancer is explored. Current live campaigns in the UK are highlighted ahead of future initiatives now that the Mouth Cancer Action Charter has been launched and two new coalitions have been established.

The incidence trends of oral cancers worldwide from 1988 to 2012 and the prediction up to 2030

BACKGROUND

This paper aims to analyze the time trend of OCs incidence in 43 countries (1988-2012) and predict the incidence trend of OCs (2012-2030).

METHODS

In the database for Cancer Incidence in Five Continents, the annual data on OCs incidence grouped by age and gender were obtained from 108 cancer registries in 43 countries. The age-standardized incidence rates were calculated, and the Bayesian age-period-cohort model was used to predict the incidence in 2030.

RESULTS

South Asia and Oceania had the highest ASR in 1988 (9.24/100 000) and 2012 (6.74/100 000). It was predicted that India, Thailand, the United Kingdom, the Czech Republic, Austria, and Japan would be the countries with an increased incidence of OCs in 2030.

CONCLUSION

Regional custom is an important factor affecting the incidence of OCs. According to our predictions., it is necessary to control risk factors according to local conditions and enhance screening and education.

An overview of the burden of oral cancer in Sri Lanka and its inequalities in the face of contemporary economic and social malaise

OBJECTIVES

Over the past several decades, oral cancer has been the most common malignancy among Sri Lankan males and the top 10 cancer among females, disproportionately affecting low socio-economic groups. Sri Lanka is a lower-middle-income developing country (LMIC), currently striking through an economic crisis, and social and political unrest. Occurring at an accessible body site and predominantly attributed to potentially modifiable health-related behaviours, oral cancer should be preventable and controllable. Unfortunately, broader contextual factors that are socio-cultural, environmental, economic, and political and mediated through social determinants of people's lives consistently hinder progress. Many LMICs with a high burden of oral cancer are now gripped by economic crises, consequent social and political unrest, all compounded by reduced public health investments. The aim of this review is to provide a critical commentary on key aspects of oral cancer epidemiology including inequalities, using Sri Lanka as a case study.

METHODS

The review synthesizes evidence from multiple data sources, such as published studies, web-based national cancer incidence data, national surveys on smokeless tobacco (ST) and areca nut use, smoking and alcohol consumption, poverty headcount ratios, economic growth, and Gross Domestic Product (GDP) health expenditure. National trends in the oral cancer, ST use, smoking and alcohol consumption in Sri Lanka are identified alongside inequalities.

RESULTS

Using these evidence sources, we discuss 'where are we now?', together with the availability, accessibility and affordability of oral cancer treatment services, oral cancer prevention and control programmes, tobacco and alcohol control policies, and finally, outline macroeconomic perspectives of Sri Lanka.

CONCLUSIONS

Finally, we speculate, 'where to next?' Our overarching goal of this review is to initiate a critical discourse on bridging the gaps and crossing the divides to tackle oral cancer inequalities in LMIC such as Sri Lanka.

Diagnostic delay of oral squamous cell carcinoma and the fear of diagnosis: A scoping review

The mortality rate of patients affected with oral squamous cell carcinoma (OSCC) has been stable in recent decades due to several factors, especially diagnostic delay, which is often associated with a late stage diagnosis and poor prognosis. The aims of this paper were to: analyze diagnostic delay in OSCC and to discuss the various psychological factors of patients with OSCC, with particular attention to the patient's fear of receiving news regarding their health; and the professional dynamics related to the decision-making processes in cases of suspected OSCC. A preliminary review of literature focusing on OSCC diagnostic delay was performed. Seven articles were included with the diagnostic delay ranging from 45  days to approximately 6  months. Patients' fears and, to a lesser degree, the concerns of dentists, were found to be still poorly investigated. On the basis of the authors' professional experience, the development of oral lesions of unknown origin may generate different behaviors in the decision-making processes by patients and clinicians, and fear may play a key role in the distinct steps of this process. It is crucial to increase awareness and inform patients about the onset of OSCC, and contemporaneously encourage experimental studies on patients' fear and professional behaviors with respect to communication regarding OSCC.

Area-level deprivation and oral cancer in England 2012-2016

BACKGROUND

The relationship between deprivation and oral cancer is complex. We examined magnitude and shape of deprivation-related inequalities in oral cancer in England 2012-2016.

METHODS

Oral cancer was indicated by cancers of the lip and oral cavity (ICD10 C00-C06) and lip, oral cavity and pharynx (C00-C14) and deprivation by the Index of Multiple Deprivation. Deprivation inequality in incidence and mortality rates of oral cancer outcomes was measured using the Relative Index of Inequality (RII). Fractional polynomial regression was used to explore the shape of the relationships between deprivation and oral cancer outcomes. Multivariate regression models were fitted with the appropriate functions to examine the independent effect of deprivation on cancer adjusting for smoking, alcohol and ethnicity.

RESULTS

Incidence rate ratios (IRRs) and mortality rate ratios (MRRs) were greater for more deprived areas. The RII values indicated significant inequalities for oral cancer outcomes but the magnitude of inequalities were greater for mortality. The relationships between deprivation and oral cancer outcomes were curvilinear. Deprivation, Asian ethnicity and alcohol consumption were associated with higher incidence and mortality rates of oral cancer.

CONCLUSION

This is the first study, to our knowledge, exploring the shape of socioeconomic inequalities in oral cancer at neighbourhood level. Deprivation-related inequalities were present for all oral cancer outcomes with a steeper rise at the more deprived end of the deprivation spectrum. Deprivation predicted oral cancer even after accounting for other risk factors.

The length of patient and primary care time interval in the pathways to treatment in symptomatic oral cancer. A quantitative systematic review

OBJECTIVES

To examine the relative length of the patient and primary care intervals in symptomatic oral cancer.

DESIGN

Quantitative systematic review.

SEARCH STRATEGY

Oral cancer OR oral squamous cell carcinoma OR oropharyngeal cancer AND time interval OR diagnostic delay.

SETTING

Primary and secondary care.

PARTICIPANTS

Oral and oropharyngeal cancer patients.

MAIN OUTCOME MEASURES

We computed five measures (patient, primary care, diagnosis, total diagnosis and total treatment intervals). Most studies did not provide any dispersion measure. We then used the sample size of each study to compute a weighted average of the mean intervals. When the median was provided, we assumed normality of the distribution of the means and used the median as a proxy of the mean.

RESULTS

A total of 1089 articles were identified, and 22 met the inclusion criteria, reporting on 2710 patients from Europe, USA, India, Australia, Japan, Argentina and Iran. The weighted average of patient interval was 80.3 days. Primary care interval was five times shorter: 15.8 days. The diagnostic interval was appreciably shorter (47.9 days) when compared with the patient interval during symptomatic period.

CONCLUSIONS

Patient interval represents the major component of waiting times since the detection of the first signs/symptoms to the definitive diagnosis of oral cancer. Thus, strategies focused on high-risk patients should be prioritised. Interventions aimed at optimising the health systems should be implemented by monitoring and facilitating diagnostic and treatment pathways of patients with oral cancer.

Low level of attention to health inequalities in prevention planning activities of the Italian Regions

Background

Health promotion and prevention activities should tackle health inequalities to reduce disparities in health among disadvantaged populations. This study aimed to assess the extent to which the Italian Regions considered health inequalities during the planning of prevention activities, to detect geographical differences and to identify the possible determinants of differences in attention to health inequalities.

Methods

The 19 Regional Prevention Plans (RPPs) developed by Italian Regions within the National Prevention Plan (NPP) 2010–2013 were assessed using a specific tool to address the level of attention to health inequalities. Univariate and multivariate analyses were performed to identify regional characteristics associated with a higher level of attention to health inequalities.

Results

Of the 702 projects included in the 19 RPPs, only 56 (8.0 %) specifically addressed issues related to health inequalities. The results of the multivariate analysis showed that a higher level of attention was associated with the macroarea of intervention ‘prevention in high-risk groups’, with the higher quality of the Strategic Plan Section of the RPP and with the higher percentage of migrants in the Region in 2010. Moreover, projects that addressed the topic of health inequalities were more likely to be developed in the Northern Regions, in Regions with a lower level of ‘linking social capital’ and with a Higher Regional Health Care Expenditure (RHCE) as a percentage of Regional Gross Domestic Product (RGDP) in 2010.

Conclusions

The level of attention to health inequalities in the regional planning process of prevention activities 2010–2013 in Italy is low. The results of this study supported the new round of prevention planning in Italy, and highlight the urgent need to increase the number of policies and interventions able to reduce health inequalities.
