  1. EPIDEMIOLOGICAL DIFFERENCES IN LUNG CANCER AND THE RELATION OF OCCUPATIONS BY HISTOLOGIC TYPES IN TURKEY SÜREYYAPAŞA CHEST DISEASES AND THORACIC SURGERY EDUCATION AND RESEARCH HOSPITAL

  2. OBJECTIVE: To clarify the differences of epidemiological factors according to years and the relationship between occupation and lung cancer at 1995-2008 in Turkey. METHODS: Lung cancer patients who were followed up by oncology department were recorded according to their epidemiological features, histological sub-groups. Clinical files of patients were analyzed retrospectively.

  3. The study was separated into three periods: (1995-97(I. period), 1999-2002(II. period), 2004-2008(III. period). There were 2708 lung cancer cases(192 women, 2517 men, mean age 57,6). Squamous cell carcinoma was the most common histological type in all three periods(49.4%,37.8%,48.6%). The incidence of gender was similar in both I. and II. periods. Smoking habit of women increased in the third period(from 4.3% to12.9%). Therefore, there was a significant increase in the percentage of lung cancer among women in this period(p<0.0001). Construction(20.7%), farming(11.4%), driver(9.3%) were higher incidence among lung cancer cases. Construction was the most common occupation for each histological type(p<0.001).

  10. CONCLUSIONS: While the incidence of lung cancer had a decreasing trend among Turkish men according to 12 years ago, it became more prominent among women during the same time. Smoking may have an important role for increasing of lung cancer among women. Because of working conditions,the risk of lung cancer was associated with several occupations. Future studies with detailed assessment methods should be evaluated the relationship between occupational exposures and lung cancer.
