Advance of theragnosis biomarkers in lung cancer: from clinical to molecular pathology and biology.

One distinct molecular subtype of non-small cell lung cancer (NSCLC) is defined by rearrangement of the anaplastic lymphoma kinase (). The increasing knowledge over the last years has enabled the continuous improvement of ALK inhibitors; however, resistance in these patients remains a major concern. In this review, we summarize recent findings in +-adenocarcinoma of the lung, highlighting the role of mutations in this specific cancer type and suggest new diagnostic strategies for the future, in order to improve patient's outcome.
