Mechanisms of peripheral neuropathy associated with bortezomib and vincristine in patients with newly diagnosed multiple myeloma: a prospective analysis of data from the HOVON-65/GMMG-HD4 trial
The Lancet Oncology , Volume 11 - Issue 11 p. 1057- 1065
Background: Bortezomib-induced peripheral neuropathy is a dose-limiting toxicity in patients with multiple myeloma, often requiring adjustment of treatment and affecting quality of life. We investigated the molecular profiles of early-onset (within one treatment cycle) versus late-onset (after two or three treatment cycles) bortezomib-induced peripheral neuropathy and compared them with those of vincristine-induced peripheral neuropathy during the induction phase of a prospective phase 3 trial.
Methods: In the induction phase of the HOVON-65/GMMG-HD4 trial, patients (aged 18-65 years) with newly diagnosed Salmon and Durie stage 2 or 3 multiple myeloma were randomly assigned to three cycles of bortezomib-based or vincristine-based induction treatment. We analysed the gene expression profiles and single-nucleotide polymorphisms (SNPs) of pretreatment samples of myeloma plasma cells and peripheral blood, respectively. This study is registered, number ISRCTN64455289.
Findings: We analysed gene expression profiles of myeloma plasma cells from 329 of 833 patients at diagnosis, and SNPs in DNA samples from 369 patients. Early-onset bortezomib-induced peripheral neuropathy was noted in 20 patients, and 63 developed the late-onset type. Early-onset and late-onset vincristine-induced peripheral neuropathy was noted in 11 and 17 patients, respectively. Significant genes in myeloma plasma cells from patients that were associated with early-onset bortezomib-induced peripheral neuropathy were the enzyme coding genes RHOBTB2, involved in drug-induced apoptosis, CPT1C, involved in mitochondrial dysfunction, and SOX8, involved in development of peripheral nervous system. Significant SNPs in the same patients included those located in the apoptosis gene caspase 9, ALOX12, and IGF1R. In late-onset bortezomib-induced peripheral neuropathy, the significant genes were SOD2 and MYO5A, involved in development and function of the nervous system. Significant SNPs were noted in inflammatory genes MBL2 and PPARD, and DNA repair genes ERCC4 and ERCC3. By contrast, early-onset vincristine-induced peripheral neuropathy was characterised by upregulation of genes involved in cell cycle and proliferation, including AURKA and MKI67, and the presence of SNPs in genes involved in these processes-eg, GLI1. Late-onset vincristine-induced peripheral neuropathy was associated with the presence of SNPs in genes involved in absorption, distribution, metabolism, and excretion-eg, rs1413239 in DPYD and rs3887412 in ABCC1.
Interpretation: Our results strongly suggest an interaction between myeloma-related factors and the patient's genetic background in the development of treatment-induced peripheral neuropathy, with different molecular pathways being implicated in bortezomib-induced and vincristine-induced peripheral neuropathy.
