Basal cell carcinoma (BCC) is the most common skin cancer worldwide. Most occur on the head and neck, where cosmetic and functional outcomes are critical. BCC can be locally destructive if not diagnosed early and treated appropriately. ⋯ Vismodegib provides a systemic treatment option. However, a consensus definition of advanced BCC is lacking. A multidisciplinary panel with expertise in oncology, dermatology, dermatologic surgery and radiation oncology proposes a consensus definition based on published evidence and clinical experience.

Nivolumab, a fully human IgG4 PD-1 immune checkpoint inhibitor antibody, blocks PD-1 and can restore anticancer immune responses by abrogating PD-1 pathway-mediated T-cell inhibition. Nivolumab is approved in Japan and the USA for the treatment of patients with advanced melanoma. A Phase I trial reported overall objective response rates of 17, 32 and 29% in patients with advanced non-small-cell lung cancer, melanoma and renal cell carcinoma, respectively, which included many heavily pretreated patients. 1-/2-year overall survival rates were 42%/24%, 63%/48% and 70%/50% for non-small-cell lung cancer, melanoma and renal cell carcinoma, respectively. ⋯ Nivolumab is associated with a manageable adverse event profile. Numerous clinical trials are investigating nivolumab alone or in combination with other therapies in multiple cancer settings. This article summarizes the development of nivolumab as of November 2014.

Review
Current and future targeted therapies for non-small-cell lung cancers with aberrant EGF receptors.
Expression of the EGF receptors (EGFRs) is abnormally high in many types of cancer, including 25% of lung cancers. Successful treatments target mutations in the EGFR tyrosine kinase domain with EGFR tyrosine kinase inhibitors (TKIs). ⋯ Because of the development of resistance to treatment of TKIs, there is a need to collect genomic information about EGFR levels in non-small-cell lung cancer patients. Herein, we focus on current molecular targets that have therapies available as well as other targets for which therapies will be available in the near future.

Vemurafenib was the first selective BRAF inhibitor licensed in cancer. It is indicated for the treatment of patients affected by advanced melanoma with BRAF V600 mutation. It has shown successful results in terms of efficacy together with a favorable toxicity profile. ⋯ Moreover, its efficacy and toxicity are compared with dabrafenib and ipilimumab. A number of trials with vemurafenib alone or in combination with other drugs are also analyzed. These trials will determine the role of vemurafenib in the treatment of BRAF mutant melanoma in forthcoming years.

Carfilzomib is a proteasome inhibitor that irreversibly binds to its target, resulting in sustained proteasomal inhibition with minimal off-target effects. As a single agent, carfilzomib has demonstrated durable antimyeloma activity with manageable toxicities, which has resulted in its approval in Argentina, Israel, Mexico and the USA for the treatment of patients with relapsed and refractory multiple myeloma. Data from ongoing Phase III studies that are evaluating carfilzomib in earlier lines of therapy may facilitate an expanded indication for this agent, as well as for regulatory approval in the EU. This article summarizes the chemistry, pharmacokinetics, pharmacodynamics and available clinical data for carfilzomib in the treatment of patients with multiple myeloma.
