A statement on vemurafenib-resistant melanoma

Abstract

Despite recent advancements in the treatment of late-stage mutant BRAF V600E/K melanomas, a major hurdle continues to be acquired resistance to BRAF inhibitors such as vemurafenib. The mechanisms for resistance have proven to be heterogeneous, emphasizing the need to use broad therapeutic approaches. In this issue, the study Stat3-targeted therapies overcome the acquired resistance to vemurafenib in melanomas by Liu et al. proposes that signal transducer and activator of transcription 3 (STAT3)-paired box 3 (PAX3) signaling may be a mechanism that is used by melanomas to resist RAF inhibitors. © 2013 The Society for Investigative Dermatology.
