Objectives: Childhood cancer survivors (CCS) are a growing population group. Current oncology treatments have led to improved patient survival rates and an increase in late effects of treatment. Endocrine disturbances, such as pituitary insufficiency, thyroid dysfunction and obesity are the most common late endocrine effects of oncology treatments. The purpose of the study was to investigate the endocrine health of CCS and to record the prevalence of late endocrine effects.
Methods: Over a period of 12 months (3/2022-3/2023), sixty CCS (32 boys), aged 10.92±4.7 years, were studied. Patients were followed-up every 3-6 months after the first endocrinological assessment.
Results: The CCS had presented with: 56.8% hematologic malignancy (46.7% acute lymphoblastic leukemia, 5% acute myeloid leukemia, 1.7% chronic myeloid leukemia, 1.7% myelodysplastic syndrome, 1.7% chronic congenital neutropenia), 18.3% solid tumors of central nervous system (3.3% pituitary germinoma, 3.3% brain glioma, 8.3% medulloblastoma, 1.7% neuroblastoma, 1.7% squamous cell carcinoma) and 24.9% other tumor (11.7% lymphoma, 3.4% ovarian germinoma, 1.7% rhabdomyosarcoma, 1.7% Ewing sarcoma, 1.7% hepatoblastoma, 1.7% Langerhanshistiocytosis, 1.7% intestinal carcinoma, 1.3% other). The mean age at diagnosis of malignancy was 7.07±4.68 years. All patients received chemotherapy, 35.0% received radiotherapy and 16.7% bone marrow transplantation while relapse occurred in 18.3%. Late endocrine effects were recorded as disturbances of: 35% thyroid, 10% pituitary, 8.3% puberty,1.7% adrenals, 18.3% glucose metabolism, 28.3% bone mass and 23.3% body weight.
Conclusion: The increased endocrine morbidity in CCS emphasizes the need for continued and thorough endocrinological follow-up of these patients as well as the importance of a structured transition to adult endocrinology care.
