Abstract

Chronic lymphocytic leukemia (CLL) is an incurable illness, with some patients requiring no treatment until disease progression. Burden from physical symptoms has been associated with depression, anxiety, and stress in cancer patients. Additionally, patient factors, i.e., individual differences, have been associated with worse psychological outcomes. There are few psychological studies of CLL, with no examination of individual differences. A cross-sectional design studied the covariation of symptom burden with depressive and anxiety symptoms and cancer-specific stress, and tested patients' individual differences as predictors and as moderators. CLL patients (N?=?112) receiving active surveillance participated. They were Caucasian (100 %) and predominately male (55 %) with a mean age of 61; most (62.5 %) had stage 0 disease. A composite measure of physical symptom burden (CLL symptoms, fatigue, pain, impaired functional status) was tested as a predictor of psychological responses. Individual differences in psychiatric history and social support were tested as moderators. Using multiple linear regression, greater symptom burden covaried with higher levels of depressive and anxiety symptoms and cancer stress (ps?
