Depression symptoms and health-related quality of life among patients with metastatic breast cancer in programme of palliative cancer care

Depression is seen in many cancer patients. It occurs in approximately 25% of palliative care patients. The quality of life term contains the information on an individual's physical, psychological, social and spiritual condition. The study evaluated incidence and relevance of depression symptoms and level of health-related quality of life (HRQoL) among patients with metastatic breast cancer in programme of palliative cancer care. This study was local, prospective and cross-sectional. It was carried at Department of Clinical Oncology and Radiation Therapy of Charles University Hospital in Hradec Kralove, Czech Republic. Dates were obtained during year 2008 among 41 patients with metastatic breast cancer in programme of palliative cancer care. The mean age for all 41 subjects was 58 years old (aged 41-80 years old). The Czech version of Zung self-rating depression scale was perfomed for evaluation of depression symptoms. The Czech version of generic EuroQol Questionnaire EQ-5D was performed for evaluation of level of HRQoL. The statistical evaluation presents that mean ZSDS (Zung self-rating depression score) certifies the presence of signs of moderately depression symptoms among patients with metastatic breast cancer (ZSDS range was 60-69). The mean ZSDS in all subjects was 60,6 The mean ZSDS in group of healthy females was 38,9 (normal range of ZSDS). The incidence of depression was 61% (25 of all 41 subjects). The relevance of depression is characterized: severely depressed was proved in 5 of all 25 subjects, the moderately depressed in 10 subjects of all 25 subjects and mildly depressed in 10 of all 25 subjects. The statistical evaluation not presents statistically significant dependence of ZSDS on age, number of associated diseases and type of palliative cancer care. The HRQoL among patients with metastatic breast cancer is on very low level. The mean EQ-5D score (dimension of quality of life) was 55%. The mean EQ-5D VAS (subjective health condition) was 59,2%. The mean EQ-5D score in group of healthy females was 78,4% and the mean EQ-5D VAS was 85% (both QoL parameters show very good of QoL level). The statistical evaluation not presents statistically significant dependence of EQ-5D score and EQ-5D VAS on age, number of associated diseases and type of palliative cancer care. The results showed that subsist clear association between metastatic breast cancer in programme of palliative cancer care and depression. Also, the results showed that subsist low level of HRQoL of patients with metastatic breast cancer.
