Population morbidity in elderly lung cancer patients from Poland with specific trends in elderly women

Introduction
Lung cancer remains a leading cause of morbidity and mortality in Poland and globally. The objective of the study was to assess lung cancer incidence among elderly patients in Poland, including data for urban and rural populations, with trend analysis between 2008 and 2012.

Material and methods
Differences between lung cancer prevalence in the Polish population aged 65 years or older were assessed with respect to province, gender, and rural vs. urban areas during the 2008-2012 period. Data were extracted from the Polish National Health Authority and Statistical Bureau databases.

Results
Lung cancer morbidity among the elderly increased by 14.05% in urban areas but only by 4.01% in rural areas. A 22.41% overall increase was noted in the elderly female population, compared to a 7.29% increase among men aged 65 years and over. Regional differences in morbidity were observed.

Conclusions
The rationale behind the differences is likely to be multi-factorial. A change in risk factor exposure in the past is probably now being reflected in lung cancer morbidity. The difference between sexes can potentially be regarded as an unfortunate side-effect of increasing female empowerment. Urban vs. rural, as well as regional, variances are probably due to a multitude of factors, including differences in socio-economic status.
