title: [A review of epidemiologic data on cancers of the nose and paranasal sinuses in Turkey].
abstract: OBJECTIVE
  To review epidemiologic data on cancers of the nose and paranasal sinuses in Turkey.
  
  
  METHODS
  The epidemiologic findings were obtained from the following sources: Cancer Registry (1995 to 1999) of the Department of Cancer Control of the Ministry of Health; records of Izmir Cancer Registry (1993-1994); Prof. Dr. Nazmi Bilir's review in 1977, in which the findings of pathology laboratories were collected; records of cancers of the nose and paranasal sinuses from 1964 to 2000 at the Otolaryngology Department of Medicine Faculty of Hacettepe University.
  
  
  RESULTS
  During the above-mentioned years, cancers of the nose and paranasal sinuses were detected in 127 patients (85 males, 42 females; mean age 47 years; range 1-89 years) in Hacettepe University, of whom 14 were children. The male to female ratio was 2.02. In Nazmi Bilir's review, cancers of the nose and paranasal sinuses were reported in 65 males and 37 females, with a frequency of 0.7% in males and 0.6% in females among all cancers. Its incidence was 0.4/100.000 for males and 0.2/100.000 for females, which was the same as that found in Izmir Cancer Registry. According to the Cancer Registry of the Ministry of Health, cancers of the nose and paranasal sinuses were most commonly encountered at the ages of 50 to 70 years, and were most common in the Marmara region followed by the Middle Anatolia region.
  
  
  CONCLUSIONS
  Registry systems in our country need to be improved in order to derive more accurate epidemiologic data concerning cancers of the nose and paranasal sinuses.
