Abstract

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common chemotoxicities. However, no effective clinical CIPN screening methods have been reported. This study aimed to investigate whether changes in heart rate variability (HRV) could predict the development of CIPN for early symptom control in chemotherapy-prescribed patients with gastrointestinal (GI) cancer. Fifty-five GI cancer outpatients undergoing palliative chemotherapy including taxanes and/or platinum compounds were enrolled. CIPN was diagnosed using National Cancer Institute Common Toxicity Criteria for Adverse Event (NCI-CTCAE). HRV measures were derived from electrocardiogram signals. Twelve weeks after starting chemotherapy, 39 (70.9%) patients who complained of NCI-CTCAE grade 1-3 sensory changes were diagnosed with CIPN. Standard deviation of normal-to-normal R-R intervals (SDNN), high frequency (HF), low frequency (LF), and LF/HF ratio changed significantly during 3 assessment periods. Percentage changes in SDNN and HF were related to the occurrence of CIPN symptoms. A decision tree model indicated that patients with a rapid percentage change decrease in SDNN and HF were CIPN-positive. Using SDNN and HF, our decision tree predicted CIPN occurrence. The changes in HRV may occur earlier than sensory CIPN symptoms.
