The field of prostate cancer has witnessed incredible progress in the last decade, owing to the approval of multiple survival-prolonging treatments for metastatic castration-resistant prostate cancer (mCRPC). Enzalutamide is a nonsteroidal androgen receptor inhibitor that targets multiple steps in the androgen receptor signaling axis. ⋯ We summarize the milestones in the development of enzalutamide in patients with prostate cancer. Special focus is placed on the results of the STRIVE Phase II clinical trial comparing head to head enzalutamide and bicalutamide in patients with nonmetastatic and mCRPC who have failed androgen deprivation and in other ongoing trials in the same setting and in earlier disease phases.

Review Meta Analysis
Risk of endocrine complications in cancer patients treated with immune check point inhibitors: a meta-analysis.
We performed a meta-analysis of the risk of endocrine adverse events associated with immune check point inhibitors. ⋯ Our meta-analysis has demonstrated that the use of immune check point inhibitors is associated with an increased risk of hypothyroidism, hyperthyroidism, hypophysitis and adrenal insufficiency compared with control.

First-generation reversible EGF receptor (EGFR) tyrosine kinase inhibitors (TKIs) changed our understanding of advanced non-small-cell lung cancer biology and behavior. The presence of sensitizing EGFR mutations in advanced non-small-cell lung cancer defines a subset of patients with a better prognosis and sensitivity to EGFR-TKIs with a better response rate, progression-free survival, quality of life and symptom control than with chemotherapy in the first-line therapy setting. ⋯ Afatinib is an irreversible pan-ErbB-TKI, active against wild-type EGFR, sensitizing and T970M-mutant EGFR, ErbB2 and ErbB4 receptors, and represents a step change between reversible first-generation and future irreversible highly specific third-generation EGFR-TKIs. Here, we review the clinical development of afatinib through the LUX-Lung trials portfolio highlighting benefits and toxicities.

ABSTRACT Rearrangement of ALK gene has been identified as exerting a potent transforming effect as driver oncogene in patients with non-small-cell lung cancer (NSCLC). Crizotinib is a small-molecule oral inhibitor of ALK, c-Met/HGF receptor and ROS1 receptor kinases. ⋯ Resistance mechanisms such as secondary gatekeeper mutations in ALK gene and activation of other oncogenes have been identified to confer acquired resistance to crizotinib. This article reviews the pharmacological properties of crizotinib, preclinical and clinical results that led to its approval in ALK-positive NSCLC and current directions of clinical research in overcoming crizotinib resistance.
