BACKGROUND: Peripheral neuropathy is one of the most common dose-limiting toxicities associated with bortezomib; it can lead to dose reductions or therapy discontinuation. Obesity has been identified as being a risk factor for the development of peripheral neuropathy with other neurotoxic anticancer agents. We aimed to evaluate the impact of obesity on the incidence and severity of bortezomib-induced peripheral neuropathy.
PATIENTS AND METHODS: This is a retrospective, single-center study of patients treated with subcutaneous bortezomib between January 1, 2012 and June 1, 2017. Eligible patients received at least 1 full cycle of subcutaneous bortezomib and had previously untreated, newly diagnosed multiple myeloma. Patients who received intravenous bortezomib or concomitant thalidomide were excluded. Patients were divided into 3 groups based on their body mass index (BMI): normal/underweight (BMI < 25), overweight (BMI = 25-29.9), and obese (BMI ≥ 30).
RESULTS: A total of 143 patients fitting the inclusion criteria were identified. Patients across the 3 groups received bortezomib at similar doses and schedules (weekly vs. biweekly). Obese patients had an increased incidence in developing bortezomib-induced peripheral neuropathy (56.4%) compared with normal/underweight (17.3%) and overweight patients (26.9%). Further analysis showed that, compared with normal/underweight and overweight patients, obesity was not found to be associated with an increased risk of grade 3 to 4 bortezomib-induced peripheral neuropathy (P = .451).
CONCLUSION: Obese patients were found to be at higher risk for the development of bortezomib-induced peripheral neuropathy compared with non-obese patients.
