Pre‐treatment symptom cluster in breast cancer patients is associated with worse sleep, fatigue and depression during chemotherapy

Abstract

A higher clinically relevant-based pre-treatment symptom cluster was associated with more sleep disturbances, greater fatigue and more depressive symptoms during chemotherapy. Specific interventions for these pre-treatment symptoms may improve the frequency and severity of these same symptoms during chemotherapy, when they are most severe and most disruptive to quality of life.
