The anaplastic lymphoma kinase (ALK) fusion gene is a key oncogenic driver in a subset of patients with advanced non-small cell lung cancer (NSCLC). Oncogenic fusion genes, including echinoderm microtubule-associated protein-like 4 (EML4) and ALK, have been detected in approximately 2-7 % of NSCLC patients. Fluorescence in situ hybridization (FISH) is the recommended method for detecting ALK gene rearrangement. ⋯ Treatment-related adverse events, predominantly restricted to the gastrointestinal and visual systems, are generally self-limiting or easily managed. Crizotinib is a new standard of care for patients with advanced, ALK-positive, NSCLC. In this review, we will discuss the discovery of ALK rearrangements, the clinical epidemiology of lung cancer driven by ALK, the clinical data for ALK-targeted therapy in NSCLC, and ongoing ALK inhibitor-based clinical trials.

Increasing knowledge of the biology of multiple myeloma led the way for the development of novel drugs that have changed the management of the disease. New treatments target not only to the malignant plasma cell but also target the interactions of myeloma cells with their microenvironment. ⋯ The identification of active agents in the laboratory is followed by rationally designed clinical studies that validate these drugs, either as single agents or in combinations with other active drugs. These novel agents may be either small molecules or monoclonal antibodies targeting receptors, kinase activity of receptors or key molecules within critical pathways, intracellular maintenance mechanisms and immune modulation.
