摘要
Verification of the cases of lung cancef, from Tianjin Cancer Registration System In 1981 - 1987, was conducted. It was suggested that lung cancer incidence and mortality had Increased and ranked first among various malignant tumors in that period. In urban area, the standardized incidence of male lung cancer was 44. 27/100,000, and was 24. 19% in malignant events; in female it was 32. 00/100, 000, and 26. 33% respectively. The ratio of male to female was 1.38. In comparing with the standardised Incidence of lung cancer in some other countries and regions, the epidemiology features of the disease in Tianjin were lower In sex ratio and higher in female Incidence, approximately similar to the levels in Shanghai and Beijing.
