Peripheral neuropathy and lifestyle factors in women with breast cancer receiving taxane-based chemotherapy: Pathway analysis

Abstract

PurposePeripheral neuropathy adversely affects the treatment process of cancer, and thus it is important to reveal the factors leading to peripheral neuropathy and to take the necessary precautions to avoid it. This study was conducted to investigate the relationship between chemotherapy-induced peripheral neuropathy (CIPN) and lifestyle factors (nutrition, physical activity and sleep quality). MethodsThis descriptive and correlational study was conducted with 108 individuals who were treated in the chemotherapy unit of a hospital between April 2021 and April 2022 in Turkey. Data were collected using the Chemotherapy-Induced Peripheral Neuropathy Assessment Tool (CIPNAT), the International Physical Activity Questionnaire (IPAQ), the Mini Nutritional Assessment Test (MNA), and the sleep level Visual Analog Scale. Number, percentages, means, and standard deviations were calculated, and multiple linear regression analysis and path analysis were conducted to analyze the data. ResultsThe results indicate that the total MET score significantly and positively predicted the sleep scale score (β = 0.24, p < 0.01), while it negatively and significantly predicted the CIPNAT score (β = −0.30, p < 0.001). In addition, both the MNA screening score and the sleep scale score significantly and negatively predicted the CIPNAT score (β = −0.25, p < 0.01, β = −0.29, p < 0.001, respectively). ConclusionsLifestyle factors (exercise, nutrition, sleep) were found to have an effect on peripheral neuropathy. It is thought that increasing the level of exercise improves sleep quality, and regular nutrition, quality sleep and increased physical activity may be effective in reducing peripheral neuropathy.
