Abstract
Slovakia currently has one of the highest incidence rates of oral cancer in Europe. Incidence data from the Slovakian Cancer Registry relating to oropharyngeal cancer are analyzed for the period 1968–1989 to examine trends in the incidence of these malignancies, representing the first such reported time series from Central Europe. Over this period, rates in males have increased from 4.5 per 100,000 in 1968–1970 to 17.9 per 100,000 in 1987–1989, with more marked increases noted amongst middle-aged males (35 to 64 years), among whom rates have increased from 6.8 to 47.9 per 100,000 over the same period. Rates in women have been relatively low and stable. Changes in rates in men follow a period during the 1950s and 1960s when there was a marked increase in alcohol and tobacco consumption. The magnitude of the increases have resulted in oropharyngeal cancer becoming an important public health problem in Slovakia and emphasizes the importance of measures to prevent further increases in the consumption of tobacco and alcohol.
