General Aspects and Mechanisms of Peripheral Neuropathy Associated With Bortezomib in Patients With Newly Diagnosed Multiple Myeloma

Introduction of the proteasome inhibitor bortezomib (Velcade, Millennium Pharmaceuticals, The Takeda Oncology Company, Cambridge, MA) has substantially improved outcomes for patients with multiple myeloma (MM), and has become one of the cornerstones of current anti-myeloma treatment regimens. However, with the introduction of bortezomib it has become clear that peripheral neuropathy (PN) is one of the most frequent, potentially disabling, nonhematologic complications of bortezomib, often requiring dose modification or discontinuation, with a potential negative impact on clinical endpoints and quality of life. To find a balance between maximal benefit of bortezomib treatment, while maintaining quality of life, it is necessary to minimize toxicity. Here, we discuss all aspects of bortezomib-induced peripheral neuropathy (BiPN), and elaborate on the mechanisms underlying the development of BiPN.
