Changes in chemotherapy-induced peripheral neuropathy, disturbance in activities of daily living, and depression following chemotherapy in patients with colorectal cancer: A prospective study

Purpose: This study was conducted to identify the changes in oxaliplatin-induced peripheral neuropathy (OIPN), disturbance in activities of daily living (ADL), and depression and their interrelationships during the cancer care trajectory in colorectal cancer patients. Methods: Eighty-six subjects participated in the study and completed the questionnaire at three time points: prechemotherapy, undergoing chemotherapy, and 3 months after the completion of chemotherapy. The assessment tools were Chemotherapy-Induced Peripheral Neuropathy 20 for OIPN, Chemotherapy-Induced Peripheral Neuropathy Assessment Tool to measure disturbances in ADL, and Hospital Anxiety and Depression Scale for depression. Data were analyzed using descriptive statistics and repeated-measures analysis of variance. Results: While undergoing chemotherapy, 37.2% of the patients complained of OIPN and 32.6% exhibited OIPN at 3-month follow-up. Repeated-measures analysis of variance showed a significant increase in OIPN after chemotherapy, which remained high at the 3-month follow-up. The most frequent symptom of OIPN was tingling feeling in the hand and foot, and the second was impotence. Disturbance in ADL by OIPN and depression showed similar patterns as OIPN. The mean score for disturbance in ADL of OIPN was 48.58. The mean score was 7.36 for depression, with a prevalence of 23.5%. There were significant correlations among the three variables, suggesting that OIPN may be casual in the OIPN- disturbance in ADL-depression symptom interrelationships. Conclusion: These results suggest that chemotherapy is highly associated with OIPN, disturbance in ADL by OIPN, and depression in colorectal cancer patients. Nursing intervention is needed to relieve depression as well as OIPN in patients undergoing chemotherapy.
