Evaluation of Bortezomib-Induced Neuropathy Using Total Neuropathy Score (Reduced and Clinical Versions) and NCI CTCAE v4.0 in Newly Diagnosed Patients With Multiple Myeloma Receiving Bortezomib-Based Induction

Conclusion NCI CTCAE may be suboptimal in comparison to TNSr and TNSc in assessment of BiPN because it may miss worsening neuropathy without functional limitation. Micro-Abstract The Total Neuropathy Score is ideal for evaluation of bortezomib-induced neuropathy. We used the reduced (TNSr) and clinical (TNSc) forms as well as the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v4.0 to assess incidence of neuropathy in patients receiving cyclophosphamide, bortezomib, and dexamethasone as induction for multiple myeloma. Out of 20 evaluable patients, 55%, 40%, and 45% developed neuropathy when assessed by TNSr, TNSc, and NCI CTCAE, respectively. We found wide variation in TNSr and TNSc even when the NCI CTCAE scale reported no progression of neuropathy.
