Abstract
Background
The proportion of lung cancers that are adenocarcinomas(ACs) is reported to be increasing in Europe. In 2006-2008 the proportion of UK lung cancers typed as AC was 26%.1 Incidence of lung cancer in females has recently stabilised in the UK.1 Knowledge of local case mix is essential for service planning.
Methods
King's College Hospital, London, UK, has a multiethnic, deprived population of 250 000. Since 1999, all lung cancers have been discussed at a multidisciplinary(MDT) meeting and recorded on a database. Data for histologically confirmed cases of primary lung cancer diagnosed over the period 2000-2009 were studied and stratified into 2-year epochs by date the patient was first seen. The Chi square for trend test was used to examine changes in proportions of cases in i)females versus males; ii)ACs and iii)SCCs versus all other tissue types.
Results
Table 1 Lung Cancer Cases 2000-9
Conclusion
The trend for increasing proportion of ACs (and decreasing SCCs) was highly significant; the proportion of ACs in our cohort since 2006 is greater than the latest UK figure and numbers of ACs do not appear to have stabilised.1 The proportion of female cases is in line with UK data and is not significantly changing.
