British Medical Journal:Influence of smoking cessation after diagnosis of early stage lung cancer on prognosis

The objective of this systematic review of observational studies with meta-analysis is to review the evidence that smoking cessation after diagnosis of a primary lung tumour affects prognosis. This results of the review provide preliminary evidence that smoking cessation after diagnosis of early stage lung cancer improves prognostic outcomes. From life table modelling, the estimated number of deaths prevented is larger than would be expected from reduction of cardiorespiratory deaths after smoking cessation, so most of the mortality gain is likely to be due to reduced cancer progression. These findings indicate that offering smoking cessation treatment to patients presenting with early stage lung cancer may be beneficial.
