This study was conducted in order to characterize the prevalence of falls and functional impairments (FIs) and their association with chemotherapy-induced peripheral neuropathy (CIPN) in cancer survivors.
We analyzed baseline assessments from a phase III RCT in cancer survivors with self-reported CIPN scores of >4 out of 10. Patients completed the EORTC QLQ-CIPN-20 for neuropathy and reported falls in the previous 3 months. FIs were defined using the Activities of Daily Living subsection of the Vulnerable Elder’s Scale. Associations of baseline characteristics and CIPN with falls and FIs were examined using logistic regression.
Of 421 patients, 11.9 % experienced recent falls and 26.6 % reported FIs. Motor neuropathy was the only factor associated with falls (OR = 1.127, p = 0.01). Factors associated with FIs included non-white race (OR = 0.335 white relative to non-white, 0.781, p = 0.01) and greater motor neuropathy scores (OR = 1.262, p < 0.0001).
CIPN, primarily motor, is associated with falls and FIs. Future prospective research should investigate the ability of motor neuropathy severity to predict falls.
