Background: Paragangliomas (PGLs) and Pheochromocytomas (PCCs) are rare cancers. There is not standard of care treatments for these cancers. The genomic landscape of PGLs and PCCs is not reported. The aim of this study is to report the mutational difference and assess the feasibility of Next Generation Sequencing (NGS) testing by Circulating Tumor DNA (ctDNA) from patients with PGLs and PCCs.
Methods: Molecular alterations in 46 plasma samples were tested using Guardant360® or Guardant360® CDx ctDNA assays from multiple institutions 2016-2021. Single nucleotide variants and indels in 54-83 genes with copy number amplifications and fusions in selected genes were detected.
Results: A total of 46 patients (24 PGLs and 22 PCCs) were included. For the 24 PGLs patients, the median age was 55 (range: 28-78);.. View More»
