Multicentre Study to Explore the Correlation Between Smoking Pattern and Clinical Efficacy of Epidermal Growth Factor Receptor (EGFR) Tyrosine Kinase Inhibitor (TKI) in Male Patients

A Multi-centre, Naturalistic Study to Explore the Correlation Between Smoking Pattern and Clinical Efficacy of EGFR TKI in Male Patients With Locally Advanced or Metastatic Non-small Cell Lung Cancer of Adeno Histology Failed 1st Line Chemotherapy

The objective is to investigate the correlation between smoking pattern and clinical efficacy of EGFR TKIs in male patients with locally advanced or metastasized non-small cell lung cancer of adeno histology who have failed 1st line chemotherapy. Health care resource usage, quality of life (EQ-5D) and practice of EGFR mutation test will also be evaluated. Current practice of EGFR mutation testing in Taiwan will be surveyed.

Inclusion Criteria:

• Male patients age 20 years or older
• Histological or cytological confirmation of NSCLC of adeno histology. If sputum is the only available sample, a second positive test is necessary for cytological confirmation
• Locally advanced or metastatic on or after first-line chemotherapy. Imaging evidence of disease progression can be either chest X ray, CT or MRI assessment on measurable lesions. If no measurable lesion is available, evaluable lesions are acceptable
