Variability and Influencing Factors of QOL in Breast Cancer Patients Having Chemotherapy

Abstract

Variability and factors influencing quality of life (QOL) in breast cancer patients having chemotherapy were examined in a longitudinal prospective cohort study in two teaching hospitals in China. Physical, mental, social/family, and functional QOL changed significantly over time with varying patterns. In addition, various factors influenced the QOL of breast cancer patients at each chemotherapy cycle. Health professionals should focus on critical time periods during chemotherapy, particularly at baseline and during the fourth and fifth cycles when the QOL in our sample was at the lowest point, and they should provide additional support to patients to ensure that chemotherapy is delivered in an optimal fashion.
