Depression and Suicide
Young adult survivors of childhood cancer may have an elevated risk for suicidality. A report from Eastern Europe compared the responses of 228 long-term survivors of childhood cancer with those of 127 controls to the Center for Epidemiologic Studies Depression Scale (CES-D) and the Suicidal Ideation and Behaviour Questionnaire. The rates of depressive symptoms reported by the childhood cancer survivors were three times the rates reported by the controls, with 13% indicating some level of suicidal ideation. Similarly, 226 adult survivors of childhood cancer seen in a survivor clinic completed the Short Form-36 (SF-36), the Beck Depression Inventory (BDI), and suicide items from the Symptom Checklist-90-Revised (SCL-90-R) and the Beck Scale for Suicide Ideation (BSS). The measures assessed whether the survivors had ever attempted suicide or whether they had experienced significant suicidal ideation within the past week; 29 participants (12.83%) reported suicidality. Suicidality was associated with younger age at diagnosis, longer time since diagnosis, cranial radiation therapy, a diagnosis of leukemia, pain, and concerns about physical appearance. Current physical condition, including pain, was associated with suicidality.[Level of evidence: II] These studies represent relatively small samples with small comparison groups and may reflect a reporting bias represented in individuals who actively attend follow-up clinics. Nonetheless, while these results are inconsistent with other findings related to psychological distress, they do suggest the need for ongoing monitoring and surveillance of adults who are survivors of childhood cancer.
Significant concern about the potential for suicide as a side effect of selective serotonin reuptake inhibitors (SSRIs) has led the U.S. Food and Drug Administration (FDA) to issue a caution about their use that includes the importance of careful monitoring of potential risks. Before this FDA Health Advisory was issued, clinical experience and the results of small clinical trials suggested that antidepressants can be safely administered to adult cancer patients, although there are no controlled clinical trials to support this position. The risk/benefit ratio for use of SSRIs may not be as favorable for children and adolescents. Several multicenter, double-blind, randomized, placebo-controlled clinical trials using SSRIs with children and adolescents with major depressive disorder but not cancer found modest improvements for fluoxetine,[28,29] paroxetine, and sertraline.[Level of evidence: I] Balancing these improvements were reports of serious adverse events that included worsening of psychiatric symptoms, increased suicidal ideation and gestures, increased conduct problems or hostility with paroxetine, and suicide and suicide attempts with sertraline.[Level of evidence: I]
