Patients with SCLC (Small cell lung cancer) have been treated differently from those with NSCLC (New-small cell lung cancer) as a different disease. Recently, even patients with NSCLC are treated differently according to histological subtypes. This change is associated with the development of new drugs, particularly molecular-targeted drugs. Because Bevacizumab can cause serious adverse effects, patients with squamous cell carcinoma histology and a history of hemoptysis are contraindicated for this drug. Pemetrexed has been approved with an anti-mesothelioma drug and was confirmed to be effective for NSCLC. However, its efficacy was not equally proved among the histological subtypes; only adenocarcinoma patients showed shorter progression-free and prolonged survival periods. Regarding tyrosine kinase inhibitors, the targeted gene alterations occur specifically in adenocarcinoma. Based on these findings, the current therapeutic strategy for NSCLC is based on the histological subtype and mutational status of EGFR and ALK. In this article, transition of the therapeutic strategy for NSCLC, characteristics of targeted gene alterations and efficacies of the targeted therapy are reviewed.

The presence of an ALK (Anaplastic Lymphoma Kinase) rearrangement is a rare molecular feature in Non-Small Cell Lung Carcinoma (NSCLC), and concerns mainly non- or light smokers, young patients, with adenocarcinoma histological type. These tumours are particularly sensitive to Alk-targeted therapies, as crizotinib. Crizotinib is usually well-tolerated. We report a case of fatal haemoptysis associated with dramatic response to crizotinib in a patient with an ALK-rearranged lung adenocarcinoma. The patient presented a mediastinal invasion with tracheal involvement and compression of the right pulmonary artery. The initial evolution under crizotinib was good with tumour response. At 6 weeks of crizotinib the patient presented a massive haemoptysis with a tracheobronchial fistula and pneumomediastinum. She died of acute respiratory failure. Our case is the first to report a fatal effect of crizotinib associated with tumour necrosis and good tumour response on a massive mediastinal infiltration. Precautions are recommended with the use of crizotinib in proximal lung tumours with vascular invasion.
