Abstract

Objective To assess the utility of oral cancer screening for the early detection of oral potentially malignant disorders ( OPMDs) and oral cancer ( OC) in a population of Oporto city. Material and Methods We conducted an OC screening program in the city of Oporto between 2010 and 2011 using two methodologies of population recruitment: Volunteers attending an OC screening day recruited via a mass media campaign; and OC screening during dental visits to a public hospital in the Oporto City. Participants' socio-demographic information and life-style habits were ascertained by interviewers, and an oral mucosal examination (screen) was conducted by previously trained and calibrated group of 20 screeners. Results A total of 727 individuals (277 males and 450 females) with a mean age of 54 years (range 18-94) were screened. During screening, we detected 22 OPMDs: 13 (59.1%) oral leukoplakias and 9 (40.9%) cases with oral lichen planus. No erythroplakias were detected. In addition, two oral carcinomas were detected, both in the T1 stages of the disease. All screen positives attended a specialist clinic following referral to confirm their diagnoses. A randomly selected sample among negative screens was also examined to assess any false negatives. The sensitivity was 96% and specificity was 98%. Significantly more positive cases were found among older individuals (≥54 years) ( P = 0.045). Conclusion Screening data suggest that new cancers and OPMDs can be detected by invitational and opportunistic screening and offer a platform to raise the awareness and knowledge on this cancer in the Portuguese population.
