The prevalence and detection of psychiatric morbidity in patients with metastatic breast cancer.

This study monitored the prevalence and detection of psychiatric morbidity in 80 women newly diagnosed with metastatic breast cancer from diagnosis of metastatic disease over a 16-month period. Patients were interviewed at home every 8 weeks using the Hospital Anxiety and Depression Scale (HADS) and an interview schedule compiled by the author to monitor contact with members of the multidisciplinary team, demographic details, current treatment and sites of metastatic spread. One way analysis of variance (ANOVA) comparing the mean anxiety and depression scores at each interview demonstrated that there were no statistically significant differences in mood across the eight interviews, though there was a trend over the course of the eight interviews for mean anxiety and depression to decrease. Using the cut off scores suggested by the authors of the HADS, the scores were then categorized into case, borderline and normal. These analyses illustrated the relatively large proportion of patients who fell into the borderline and case ranges for anxiety and/or depression with, for example, 39% of women scoring in the case range for anxiety and 31% for depression at diagnosis of metastatic breast cancer. Detection of these mood problems was extremely low with referral to appropriate services not in evidence. The results of this study are consistent with those of other studies monitoring the psychological needs of women with breast cancer and the detection of mood disturbance. The clinical relevance of the results of the present study are discussed and future research avenues suggested.
