Treatment of childhood cancer is a highly stressful experience, challenging and disruptive to children and their family members. It is therefore assumed that children undergoing cancer treatment are at significantly higher risk for depression, anxiety, and other indicators of psychological distress. However, the empirical evidence to support this assumption is weak. Overall, studies suggest that children treated for cancer and children who are long-term survivors of cancer experience few significant psychological adjustment problems.[1,2,3]
There is evidence that children experience distress during the cancer treatment process. Distress appears to be most significant early in therapy, typically when frequent hospitalizations are necessary, with a pattern of less distress occurring over time.[4,5] One group of 39 families of children newly diagnosed with leukemia was compared with a group of 49 families of healthy children. While parents and the children treated for cancer reported higher levels of distress immediately following diagnosis, these levels of distress decreased over 4 years of follow-up, and there were no significant differences in psychological distress compared with the healthy comparison cohort. Similar findings have been reported across cultures.
Melanoma is a malignant tumor of melanocytes, which are the cells that make the pigment melanin and are derived from the neural crest. Although most melanomas arise in the skin, they may also arise from mucosal surfaces or at other sites to which neural crest cells migrate, including the uveal tract. Uveal melanomas differ significantly from cutaneous melanoma in incidence, prognostic factors, molecular characteristics, and treatment.

The validity of obtaining accurate reports of psychologic distress in this population has been questioned. One investigation of whether psychological defensiveness might mask the reporting of depression and other symptoms of psychological distress studied 107 children treated for cancer and 422 healthy controls who completed a series of measures of depression and anxiety.[Level of evidence: II] Children treated for cancer reported significantly fewer depressive symptoms than did healthy children, and defensive style was not related to report of depression. Another study of 205 children and 321 parents of children with either cancer, asthma, or no significant health problem also found no significant levels of depression in children treated for cancer. However, parents of children with cancer attributed more cheerful characteristics to their children than did the parents of children in the other groups.[Level of evidence: II]
Studies have reported no differences from controls on the following measures:
