Health-related quality of life and its influencing factors in patients with breast cancer based on the scale QLICP-BR

Breast cancer is the most common cancer and the leading cause of cancer death among females worldwide. During the past 15 years, quality of life (QOL) has become an important aspect of breast cancer treatment. The purpose of this study was to evaluate QOL of breast cancer patients in China, and investigate its associations with sociodemographic and clinical variables. A cross-sectional study was conducted in 246 breast cancer patients in China. Recruited patients were surveyed for QOL using the QOL instruments for cancer patients-breast cancer QLICP-BR (V2.0). We assessed the associations between potential influencing factors and QOL using multiple linear regression models. The general mean QOL score for our population was 70.24 with SD = 8.70. Results indicated that medical insurance, drinking history, alkaline phosphatase, serum chloride ion level, serum calcium ion level, serum phosphorus ion level, mean corpuscular volume, mean corpuscular hemoglobin, red cell volume distribution width and platelet had significant associations with QOL of breast cancer patients. Our results emphasized that many factors are affecting QOL of breast cancer patients, which may provide a reference for targeted management or intervention strategies of breast cancer patients to improve their QOL.
