Breast cancer is associated with the occurrence of multiple symptoms, which can lead to negative consequences on the patient's physical status, social life, and psychological and financial status. Symptoms that are correlated with each other are known as Symptom Cluster (SC). Pain, fatigue, depression, sleep disturbances, anxiety, nausea, vomiting, constipation, and other symptoms are reported frequently in samples of women with breast cancer (Kirkova, Ryibicki, Walsh, Aktas, Davis, & Karafa, 2011). These symptoms have negative effect on performance status (PS) in different stages of breast cancer. Depression, anxiety, and sleep disturbances are often reported in the psychoneurological SC. Examining the effect of SCs on performance status (PS) in advanced stages of breast cancer can alleviate their effect on performance and thereby improve a patient's quality of life. This study examined the effect of the pain SC on one or more symptoms of the psychoneurological SC and PS in advanced breast cancer.
