Validation and Clinical Application of the Chinese Version of the M. D. Anderson Symptom Inventory(MDASI-C) in Breast Cancer Patients
Abstract Purpose To validate and use the Chinese Version of the M. D. Anderson Symptom Inventory (MDASI-C) to assess the symptom burden of breast cancer patients of China. And to reveal the features of the symptoms and provide a basis for improving their quality of life.Methods A total of 342 breast cancer patients participated in the study. All patients had pathological diagnosis. They were investigated and evaluated from November 2020 to February 2021 with MDASI-C. The reliability and validity were evaluated respectively. Cluster analysis and correlation analysis were carried out.Results The Cronbach’s alpha coefficient of the symptom and interference items was 0.827 and 0.880, respectively, which meant good reliability. Construct validity revealed a four-factor structure. The Kaiser- Meyer-Olkin (KMO) value was 0.760, which meant good construct validity. The patient's KPS, treatment phase and cancer stage were grouped, and the differences of scores within the groups were significant. The patient's employment status, education level and age had a significant correlation with symptoms. The top three symptoms were disturbed sleep (3.10 ± 2.52), diffificulty remembering (2.54 ± 2.30) and fatigue (2.24 ± 2.13). The higher the patient's education, the lower their symptoms. Patients' Body Mass Index (BMI), hemoglobin (Hb), alkaline phosphatase (ALP), neutral granulocyte lymphocyte ratio (N/L), and serum albumin globulin ratio (A/G) also had an effect on some of the symptoms of patients. Conclusions MDASI-C is a reliable and effective assessment tool when evaluating patients with breast cancer of China. The symptoms were related to many clinical, biochemical indicators.
