The impact of erlotinib use in non-small-cell lung cancer patients treated in a private reference general hospital and in a private cancer clinic from 2005 to 2011.

Objective: To report the demographic data and clinical outcomes of non-small-cell lung cancer patients exposed to erlotinib in any line of treatment.

Methods: This was a retrospective cohort study of nonsmall-cell lung cancer patients from a reference general hospital and a private oncology clinic, who received erlotinib from 2005 to 2011. Statistical analysis was performed and we evaluated demographic data and response to treatment, by correlating the results of this first cohort published in Brazil with results of current literature.
