“…The higher rate of cancer-related death in older patients is consistent with findings from other population-based studies of head and neck cancer (61,62), as is the positive association between area-level deprivation and mortality (63)(64)(65). Moreover, the fact that our smoking results were adjusted for deprivation makes socioeconomic confounding an unlikely explanation for our findings in relation to smoking.…”

Background: Some studies suggest smoking may result in poorer clinical outcomes in head and neck cancer, but the evidence is heterogeneous and some of it is poor quality. In a large, population-based, study we investigated: (i) whether smoking at diagnosis is an independent prognostic factor for cancer-specific survival in head and neck cancer; and (ii) whether the association varies by site and treatment.Methods: Head and neck cancers (ICD10 C01-C14, and C30-32) diagnosed from 1994 to 2009 were abstracted from the National Cancer Registry Ireland, and classified by smoking status at diagnosis. Follow-up was for 5 years or until December 31, 2010. Multivariate Cox proportional hazards models were used to compare cancerspecific death rates in current, ex-, and never smokers. Subgroup analyses by site and treatment were conducted.Results: In total, 5,652 head and neck cancers were included. At diagnosis, 24% were never smokers, 20% exsmokers, and 56% current smokers. Compared with never smokers, current smokers had a significantly raised death rate from cancer [multivariate HR, 1.36; 95% confidence interval (CI), 1.21-1.53]. The association was similar after restriction to squamous cell tumors. A significantly increased cancer-related death rate was seen for current smokers with oral cavity, pharyngeal, and laryngeal cancers. The association was stronger in surgically treated patients [HR, 1.49; 95% CI, 1.25-1.79; P(interaction) ¼ 0.01]. Neither radiotherapy nor chemotherapy modified the effect of smoking.Conclusions: Patients with head and neck cancer who smoke at diagnosis have a significantly increased cancer death rate.Impact: Greater efforts are needed to encourage and support smoking cessation in those at risk of, and diagnosed with, head and neck cancer.

“…The situation may be further complicated by poor socio-economic conditions. Living in a disadvantaged neighbourhood with low individual socioeconomic status (SES) and having less or no education reduces the probability of 5570 survival (Yeole et al, 2000;Dikshit et al, 2012;Lee et al, 2012). At the national level, factors like life expectancy, gross national product, literacy rate, health expenditure, physician density and efficiency of health care system have a formative role in controlling the oral cancer mortality (Sargeran et al, 2008).…”

The prevalence of oral cancers (OC) is high in Asian countries, especially in South and Southeast Asia. Asian distinct cultural practices such as betel-quid chewing, and varying patterns of tobacco and alcohol use are important risk factors that predispose to cancer of the oral cavity. The aim of this review is to provide an update on epidemiology of OC between 2000 and 2012. A literature search for this review was conducted on Medline for articles on OC from Asian countries. Some of the articles were also hand searched using Google. High incidence rates were reported from developing nations like India, Pakistan, Bangladesh, Taiwan and Sri Lanka. While an increasing trend has been observed in Pakistan, Taiwan and Thailand, a decreasing trend is seen in Philippines and Sri Lanka. The mean age of occurrence of cancer in different parts of oral cavity is usually between 51-55 years in most countries. The tongue is the leading site among oral cancers in India. The next most common sites in Asian countries include the buccal mucosa and gingiva. The 5 year survival rate has been low for OC, despite improvements in diagnosis and treatment. Tobacco chewing, smoking and alcohol are the main reasons for the increasing incidence rates. Low socioeconomic status and diet low in nutritional value lacking vegetables and fruits contribute towards the risk. In addition, viral infections, such as HPV and poor oral hygiene, are other important risk factors. Hence, it is important to control OC by screening for early diagnosis and controlling tobacco and alcohol use. It is also necessary to have cancer surveillance at the national-level to collect and utilise data for cancer prevention and control programs.

The aim of this study was to evaluate the association between individual and contextual variables related to self-perception in oral health among residents in the municipality of São Leopoldo, Rio Grande do Sul State, Brazil. The cross-sectional design involved 1,100 adults in 38 census tracts. The self-perception was evaluated using the Oral Health Impact Profile (OHIP-14) tool. A logistic multilevel analysis was performed. The multivariate analysis revealed that those who are of the female gender, older, with lower scores of quality of life and less social support, with poor healthy eating habits, smokers and those living in low-income census tracts presented higher odds of reporting worse oral health self-perception (OHIP-1). We concluded that individual and contextual variables are associated with oral health self-perception. This is essential information for planning health services wishing to meet the health needs of the population.
