Background
Lung cancer is the most common cancer in the world with an estimated 1.6 million new cases diagnosed in 2008 but its incidence varies considerably within
different areas in England. Socio-economic status of an individual has long been established a fundamental determinant factor in the incidence and prognosis
of majority of illnesses and the aim of this study is to explore the impact socioeconomic status has on the incidence of lung cancer patients in Liverpool over a
3-year period.

Results
80% of the patients diagnosed with lung cancer reside in the 5th quintile (the
most deprived socioeconomically) and over 93% of the newly diagnosed lung
cancer patients live within the 4th and 5th quintiles. There was no single case
of a new lung cancer diagnosis from Liverpool residents living in the 1st
recorded in the 2nd quintile.
Conclusion
This study showed that lung cancer predominantly affects people with
public health work should be carried within deprived communities in order
to reduce the inequalities gap for lung cancer.
Material and Methods
Hospital Episodes Statistics (HES) data from Liverpool Primary Care Trust (LPCT)
was used to identify new cases of Lung cancer patients diagnosed between
classes (Quintiles) based on their residential postcodes using the Index of
deprivation for small areas (Lower Super Output Areas) and each quintile
characteristics.
