Early Onset Psychosis in a Pediatric Oncology Setting: A Case Report.

Schizophrenia (SCZ) and schizoaffective disorder (SHZ) are psychiatric disorders commonly identified in individuals in their late adolescence or early adulthood. Comorbidities are common, though a concurrent diagnosis of leukemia, one of the most frequently occurring cancers of adolescence, has not yet been described in such cases. This case study outlines the clinical presentation, course, and treatment response of two 17-year-old male adolescents whose psychotic disorders complicated their leukemia treatment. The first patient was diagnosed with leukemia and subsequently with SCZ while undergoing leukemia treatment. The second patient was diagnosed with SHZ prior to the onset of leukemia. The case study will follow the methodology of Robert E. Stake (Abma & Stake, 2014), as the two cases share a leukemia diagnosis and the reported mental health impact connected with cancer-directed treatment. Early identification and treatment are critical for both psychotic disorders and cancers, often impacting the long-term prognosis. However, when co-occurring, their interplay can present unique challenges to care.
