ABSTRACT

Background: Oral cancer is a common neoplasm worldwide, mostly corresponding to squamous cell carcinoma(OSCC). Unfortunately, its overall prognosis remains poor, with no improvement in recent decades. In this study,we have analysed the epidemiological, clinical, and prognostic characteristics of OSCC on patients of a specificSpanish region (Galicia), in order to improve its prognosis and apply effective preventive and early diagnosismeasures.Material and Methods: We retrospectively analysed 243 cases of OSCC, diagnosed and treated in a single hospitalcentre in Galicia between 2010 and 2015 (minimum of 5 years of evolution). Overall and specific survival werecalculated (Kaplan-Meier) and associated variables were identified (log rank test and Cox regression).Results: The mean age of the patients was 67 years, with the majority being male (69.5%), smokers (45.9%) andalcohol consumers (58.6%), who lived in non-urban areas (79.4%). Cases diagnosed at advanced stages entailedthe 48.1% of the sample, and 38.7% of cases relapsed. The 5-year overall and disease-specific survival rates were39.9% and 46.1%, respectively. Patients who consumed tobacco and alcohol had a worse prognosis. OSCC casesreferred to hospital by specialist dentists had a better prognosis, as those who were previously diagnosed with anoral potentially malignant oral disorder (OPMD) or received dental care during OSCC treatmen. Conclusions: In view of these findings, we conclude that OSCC in Galicia (Spain) still has a very poor overall prog-nosis, which is mainly related to the advanced age of the patients and the late diagnosis. Our study highlights thebetter survival of OSCC in relation to the referring health professional, the presence of a previous OPMD and thedental care after diagnosis. This demonstrates the importance of dentistry as a health profession involved in the earlydiagnosis and multidisciplinary management of this malignant neoplasm.(AU)

ABSTRACT

Background: Chili is the most heavily and frequently consumed spice, either as a flavouring or colouring agent,and it is also a major source of pro-vitamin A, vitamin E and C. The main capsaicinoid found in chili peppers iscapsaicin. It has been demonstrated that capsaicin acts as a cancer-suppressing agent through its antioxidant andanti-inflammatory effects, by blocking several signal transduction pathways. Oral squamous cell carcinoma isone of the most prevalent cancer worldwide. It is noteworthy that in countries where populations of diverse ethnicgroups co-exist, differences have been observed in terms of incidence of oral cancer. The variances in their dietcould explain, at least in part, these differences. The objective of this systematic review is to explore if there isevidence of a possible relationship between capsaicin intake and the incidence of oral squamous cell carcinoma,and discuss such association.Material and Methods: A bibliographical search was made in PubMed, Scopus and Web of Science databases, andfinally 7 experimental studies were included; OHAT risk of bias tool was used to assess their quality.Results: All the studies confirm that capsaicin is a chemopreventive agent that prevents the development of oralcancer, through inhibition of malignant cell proliferation and increase of apoptosis.Conclusions: More human studies are needed in order to clarify the real link between consumption of chili (cap-saicin) and the prevalence of oral cancer.(AU)
