Knowledge and behaviors of primary care physicians on oral cancer in Italy

Abstract

We investigated the knowledge and behaviors of a random sample of 500 primary care physicians (PCPs) regarding oral cancer in Calabria (Italy). 87.6% and 64% indicated tobacco and alcohol use as risk factors, only 31.5% and 2.8% having a prior oral cancer lesion and older age. 60.9% knew that squamous-cell carcinoma is the most common form; 68.8% and 37.1% that the tongue and floor of the mouth were the two most common sites. Respectively 91.5% and 41.7% knew that leukoplakia and erythroplakia were the two conditions most likely to be associated with oral cancer. 17.6% of PCPs recognized that an early oral lesion usually is small and painless red area and 26.8% knew how to examine the tongue. PCPs who learned about oral cancer from scientific journals were more likely to indicate tobacco use as a risk factor for oral cancer and those who do not need additional information to indicate alcohol use as a risk factor. Oral examination was provided by 63.8% and 37.1% to those 40 years of age and older. Half of respondents asked about the personal patient’s experience of oral cancer and about the patient’s family, most about patients’ tobacco and alcohol use. The odds of asking about patients’ tobacco and alcohol use and of performing oral cancer examination were significantly higher for those who practiced medicine for a longer period. Additional training and continuing educational programs on prevention and early detection of oral cancer for PCPs are strongly needed.
