Lung cancer is in Poland the most common malignancy. Non-small cell lung cancer (NSCLC) accounts for approximately 80% of all lung tumors. In the multidisciplinary treatment of non-small cell lung cancer patients the role of chemotherapy and, most recently, molecular targeted therapy is increasing. In 2005 we published recommendations for systemic treatment of non-small cell lung cancer and mesothelioma. As many new studies have been published since, it was necessary to update this document. We present here a consensus statement on this topic, prepared by a panel of experts in oncology, thoracic surgery, pathology and pneumonology.
