Background. Hematopoietic stem cell transplantation (HSCT) is a curative treatment option for malignant and nonmalignant diseases that is highly distressing, especially for children. A valid assessment of pediatric patients’ distress that is independent from their language skills would be beneficial. Research regarding HSCT-specific self-reporting or rater-reporting instruments is scarce. Method. In this single-center prospective study, pediatric patients and young adolescents undergoing HSCT were screened for mental and somatic distress using PO-Bado (Basic Documentation for Psycho-Oncology) ratings from parents and medical caregivers on eight observations days before, during, and up to 200 days after HSCT. Additionally, the stress biomarkers cortisol and α-amylase were monitored on the same observation days. Results. A total of 39 pediatric and young adult patients with a median age of 9.3 years (range 0.5–19.0), with 18 females (46%) and 21 males, were enrolled. The perceptions of the patients’ somatic and mental distress of parents and medical caregivers of patients were significantly correlated (mental subscale ((r(276) = 0.31, p < 0.001 ., 95% CI of the correlation: (0.20, 0.41)) and somatic subscale ((r(284) = 0.46, p < 0.001 ., 95% CI of the correlation: 0.36, 0.54)). The time period between the days of transplantation until day +10 was rated as the most mentally and somatically distressing. Conclusions. While the somatic burden declined over time, the mental distress in the patients remained at a stable level, emphasizing the importance of further psychological and psycho-oncological support in these patients. The use of salivary α-amylase as a suitable distress detection marker in pediatric patients undergoing HSCT should be further investigated.
