Mood and clinical status in patients with multiple myeloma

Abstract

Two hundred ninety patients with a recent diagnosis of multiple myeloma were studied psychologically at the time of initial treatment. Physician- and patient-completed psychosocial scales were correlated with physical variables used to measure tumor load and physical status. A logistic regression model was used to analyze objective response to treatment. Indirect measures of response to treatment were obtained, and factors influencing survival duration were studied using a Cox regression model. If physical variables were controlled, there were no significant correlations between psychologic scores on entry and response to treatment or survival duration. Thus, the notion that mood influences disease outcome once the disease process has begun in patients with multiple myeloma is not supported by this data set.
