Purpose: estimates from the International Agency for Research on Cancer, indicate approximately 1.8 million new lung cancer (LC) in 2012 alone. This study aimed to verify trends in incidence and mortality from lung cancer in São Paulo.
Methods: incident lung cancer cases (code C34 in ICD-10) from 1997 to 2012 were obtained from the Population-based Cancer Registry in São Paulo. Deaths were obtained from DATASUS database for the same period (1997 to 2012) and ICD-10 code (C34). The incidence and mortality rates (per 100,000) were calculated based on the population provided by IBGE and adjusted for the world population of SEGI. The trend analyzes were carried out for incidence, mortality and age groups (40-49, 50-59, 60-69, ≥70 years), using the Joinpoint software. The results were presented as annual percent change (APC).
Results: 27,107 incident cases (62.5% in men) and 23,842 deaths (63.9% in men) occurred in the period. There was a significant reduction in incidence of -7.6%/year and 3.5%/year in men and women, respectively. This pattern was seen for all age groups and both sexes. In regards to mortality, decreasing trends, though less pronounced (2.3%/year), were observed for men. As for women, mortality has been increasing 0.7% annually. This increase is more accentuated in women aged 50 and older. Mortality remained stable for women aged 40-49 years.
Conclusion: the important reduction in incidence of lung cancer for both sexes, which seems to be a related to the decreasing trends in tobacco smoking prevalence in the Municipality of São Paulo, a result of anti-tobacco policies.
