Abstract
Purpose
To describe the prevalence, severity, and risk factors of chemotherapy-induced peripheral neuropathy (CIPN) and its impact on function and quality of life (QOL) among women treated for breast cancer in a large U.S. Community Oncology practice.
Methods
Women previously treated with taxane-based chemotherapy for early-stage breast cancer completed the EORTC QLQ–C30, QLQ–BR23, and QLQ–CIPN20. Subscales are scored 0–100; higher scores indicate greater symptom severity. Pre-specified hypotheses were tested.
Results
126 women with mean age 56.7 years (SD 11.8) were stage I–II (79.4%) or stage III (20.6%) at the time of the survey; 65.1% were White and 27.8% were Black or African American. The mean time since last taxane chemotherapy cycle was 144.9 weeks (SD 112.9). 73.0% reported having CIPN. QLQ–CIPN20 mean scores for the sensory, motor, and autonomic subscales were 18.9 (SD 23.1), 18.6 (SD 18.7), and 17.1 (SD 21.8), respectively. CIPN symptom severity was negatively correlated with global health status/QOL and physical and role functioning (range of r = −0.46 to −0.72). It was not associated with age, body mass index, diabetes, or cumulative taxane dosage, but was greater for Black or African American women (e.g., sensory, p < 0.002). CIPN sensory impairment was marginally greater for patients treated with paclitaxel compared to docetaxel (p < 0.064).
Conclusions
CIPN was prevalent in this community oncology practice and significantly impacts function and QOL. These data highlight the importance of developing methods to mitigate CIPN, and for screening for CIPN particularly among Black or African American women.
