Psychological distress of adolescent and young adult childhood cancer survivors in a South African cohort

BackgroundWe investigated psychological distress in a South African childhood cancer survivor (CCS) cohort. MethodsAdult CCSs treated at Tygerberg Hospital, Cape Town, completed the Brief Symptom Inventory-18. Internal consistency was acceptable: Cronbach's alpha values were 0.91 (Global Severity Index (GSI)), 0.85 (depression), 0.83 (somatization), and 0.75 (anxiety). We compared results utilizing different case rules (GSI T scores of >= 50, >= 57, and >= 63) for the identification of psychological distress. ResultsForty CCSs (median age 24 years; median follow-up period 16 years) participated. Most (58%; 23 out of 40) completed school or tertiary education, were unmarried (90%; 36 out of 40), and unemployed (59.5%; 22 out of 37). The diagnoses included hematological malignancies (65%; 26 out of 40) and solid tumors (35%; 14 out of 40). The GSI T scores of >= 63, >= 57, and >= 50 identified 10% (four out of 40), 32.5% (13 out of 40), and 45% (18 out of 40) of survivors with psychological distress, respectively. Radiotherapy (odds ratio (OR) 4.6; p = .035), presence of >= six late effects (OR 7.5; p = .026), and severe late effects (OR 6.6; p = .024) were significant risk factors (GSI T score >= 57). Follow-up period of 11-20 years (OR 7.3; p = .034) was significant for a GSI T score >= 50. ConclusionThis South African CCS cohort had higher levels of psychological distress utilizing the GSI T score >= 50 and >= 57 case rules than reported in the literature. Most were unmarried or unemployed. Significant contributing factors were radiotherapy, number and severity of late effects, and follow-up period. CCSs must be screened for psychological distress.
