Revealing symptom profiles: A pre-post analysis of docetaxel therapy in individuals with breast cancer

Purpose: This study aimed to explore the symptom profiles and predominant symptoms in newly diagnosed breast cancer women before and after receiving docetaxel chemotherapy. Methods: A pre-post study recruited adult women with stage I-III breast cancer undergoing docetaxel chemotherapy using convenience sampling. The 13-item symptom severity subscale of the M. D. Anderson Symptom Inventory-Taiwan Form was used to measure symptoms. The study employed latent profile analysis to identify subgroups based on symptom severity before and after docetaxel chemotherapy. Descriptive statistics, including mean and frequency, were used to compare and contrast the most prevalent and severe symptoms within each subgroup to confirm the predominant symptoms. Results: The study identified four and two symptom profiles before and after docetaxel treatment, respectively. Disturbed sleep was identified as a prevalent symptom for all participants, regardless of their chemotherapy status. The predominant symptoms before treatment were disturbed sleep, dry mouth, difficulty remembering, and fatigue, while disturbed sleep and numbness were the predominant symptoms after treatment. Conclusion: The findings of this study are significant, as they contribute to the current understanding of the symptom experience of breast cancer individuals undergoing docetaxel chemotherapy. Healthcare professionals should prioritize assessing and managing these symptoms, including identifying contributing factors to poor sleep. Addressing symptom profiles related to sleep can improve the quality of life of breast cancer individuals undergoing docetaxel chemotherapy.
