| Summary: | Background and purpose: There remains limited evidence regarding the relative neurotoxic potential of nab-paclitaxel long-term. This cross-sectional matched cohort study aimed to compare the severity and natural history of chemotherapy-induced peripheral neuropathy (CIPN) between patients treated with nab-paclitaxel and patients treated with oxaliplatin or paclitaxel using a suite of clinical, patient reported, and neurophysiological assessments.
Patients and methods: CIPN assessments included the total neuropathy score (TNSc), grooved pegboard assessment, sensory assessments (grating orientation task and Von-Frey assessment), patient-reported outcome measures, and neurophysiological studies. The matched cohort included 72 patients (24 nab-paclitaxel, 24 paclitaxel, and 24 oxaliplatin); each stratified into two groups by time post-treatment, 0–4 months, and > 6 months.
Results: Chronic neuropathy was reported by 71% of nab-paclitaxel-treated patients, most prominently numbness in the lower limbs. Longer time post-treatment was associated with significantly better TNSc scores (p = 0.044). Neuropathy severity was similar for nab-paclitaxel and paclitaxel. Neuropathy severity was worse for oxaliplatin compared to nab-paclitaxel, as measured by sensory function (p < 0.05) and sural amplitude (p = 0.003), but similar for patient-reported and neurological-graded assessments.
Interpretation: These findings underscore the importance of inclusion of a range of multimodal CIPN assessments to characterize relative burden of toxicity between chemotherapy agents. CIPN severity was similar between nab-paclitaxel and paclitaxel cohorts, but more severe in oxaliplatin-treated patients.
