#4174 Uncovering the genomic profiling of metastatic pheochromocytomas and paragangliomas: Leveraging plasma circulating tumor DNA for comprehensive genetic characterisation and monitoring

Introduction: Liquid biopsy, notably plasma circulating tumor DNA (ctDNA), is a non-invasive approach to elucidate the tumoral genomic profile from a blood sample. Pheochromocytomas and paragangliomas (PPGL) are often operated, characterized by quiet genomes and usually indolent tumor growth. However, challenges arise with metastatic tumors due to accessibility, catecholamine-related crises and surgery issues. Thus, molecular mechanisms transitioning from indolent to metastatic tumors are largely unexplored.

#2972 Characteristics and Management of Paragangliomas, 10 Years Experience

Introduction: Paraganglioma (PG) is a rare extra-adrenal neuroendocrine tumor, with common sites of presentation being abdomen, and head and neck region. The majority of PGs appear to be sporadic. However, almost half of cases are associated with an inherited syndrome. The highest malignancy rates are seen in paragangliomas (PGs) associated with SDHB mutations, which are usually abdominal and secretory.
