Evaluate the Impact of Afatinib on Quality of Life and Symptom Burden of Greek Subjects With Advanced NSCLC in Routine Patient Care Settings

Number of patients who experience a minimum clinically important improvement in symptoms is reported. A patient was categorized as having an improvement if the mean score of any two consecutive post-baseline Average Symptom Burden Index (ASBI) score of Lung Cancer Symptom Scale (LCSS) assessments for that patient was at least 10 points below the patient's ASBI score of LCSS at enrolment, over 6 months of treatment. The patient-rated scale consists of six symptom-specific questions that address loss of appetite, fatigue, cough, dyspnoea, pain and haemoptysis. Each item is scored on a 100-millimeter (mm) Visual Analogue Scale (VAS), with score reported from 0 to 100, with 0 representing the best score. ASBI score was calculated by the mean of the 6 major lung cancer symptoms (loss of appetite, fatigue, cough, dyspnoea, pain and haemoptysis). For a given assessment, if any of the six symptom-specific questions was not completed, the ASBI score was not calculated.
