A new prospective study of more than 500 adults who were current smokers when diagnosed with lung cancer, published today in the Annals of Internal Medicine, provides robust evidence indicating that quitting smoking after diagnosis of lung cancer is associated with significant improvement in overall survival and disease-free survival among these patients.
This report is based on a 15-year collaborative study between the International Agency for Research on Cancer (IARC) and the N.N. Blokhin National Medical Research Centre of Oncology of the Russian Academy of Medical Sciences. This study recruited 517 patients with newly diagnosed non-small cell lung cancer who were current smokers, from the departments of thoracic surgery at two sites in Moscow, Russian Federation, and followed them up annually for an average of 7 years to record any changes in their smoking behaviour and disease status.
