What this trial studies

This clinical trial aims to improve the diagnosis of histiocytosis in pediatric patients by evaluating the molecular profile of tumor tissues and free-circulating DNA. It involves a prospective, low-intervention approach where the efficacy of fluorodeoxyglucose (18F-FDG) in PET-CT imaging will be assessed. The study is part of the POLHISTIO project, which focuses on understanding the mutations associated with histiocytosis and their clinical implications. Additionally, an immortalized cell line will be developed to explore the disease's pathogenesis and treatment responses.

Who should consider this trial

Good fit: Ideal candidates for this study are pediatric patients under 18 years of age with confirmed or suspected histiocytosis.

Not a fit: Patients who are pregnant or have other acute disorders that may complicate their participation will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more accurate diagnostics and better treatment strategies for children with histiocytosis.

How similar studies have performed: Other studies have shown promise in using molecular profiling and advanced imaging techniques for similar conditions, indicating a potential for success in this approach.
