Breast Cancer Clinical Trial
— MELODYOfficial title:
The Effect of Melatonin on Depression, Anxiety, Cognitive Function and Sleep Disturbances in Breast Cancer Patients
The purpose of this study is to investigate the effect of 6 mg melatonin daily for 1 week preoperatively to 12 weeks postoperatively on depressive symptoms, anxiety, cognitive function and sleep disturbances in breast cancer patients. Furthermore the investigators will examine whether a specific clock-gene (HPER3) is correlated with an increased risk of depression, sleep disturbances or cognitive dysfunction.

Primary | Major Depression Inventory (MDI)- Depression at One Point in the Study | MDI is a self-rating depression scale with 12 questions. MDI has previously been investigated in a Danish population. On a six-point Likert scale, the items measure how much time the symptoms have been present during the last 14 days. MDI is scored according to specific guidelines and can be used either as a rating scale or diagnostic instrument. For inclusion we used the diagnostic instrument (depression was an exclusion criteria) and for all other MDI measurements we used the rating scale. Diagnostic scale using the ICD-10 algorithm: Mild depression: 2 core symptoms and 2 other symptoms Moderate depression: 2 core symptoms and 4 other symptoms Severe depression: 3 core symptoms and 5 other symptoms Rating scale: No depression - score from 0-20 Mild depression - score from 21-25 Moderate depression - score from 26-30 Severe depression - score from 31-50 |

Secondary | Incidence of Postoperative Cognitive Dysfunction (POCD) App. 2 Weeks Postoperatively. | Calculations for POCD were based on normative data from 133 females aged 40-60 years. We evaluated changes from the preoperative baseline to the 2 postoperative test sessions. In controls we calculated mean and standard deviations (SD) of these differences. The mean change in this group may be taken as estimated learning effects. For the individual patients, we compared baseline scores with the 2- and 12-week postoperative test results, subtracted the average learning effect from the changes and divided the result by the SD of the control group to obtain a Z score for the 7 individual test outcomes. A large positive Z score indicated deterioration in cognitive function from baseline in patients. We defined a composite Z score as the sum of the 7 Z scores and normalized this using the SD for that sum in the controls. POCD was defined as a combined Z score >1.96 or a Z score >1.96 in at least 2 of the 7 subtests. Units of measure = % of patients with YES to POCD |
App. 2 weeks postoperatively | No |
Secondary | Incidence of Postoperative Cognitive Dysfunction (POCD) App. 10 Weeks Postoperatively | Calculations for POCD were based on normative data from 133 females aged 40-60 years.
