Short Review: Genomic alterations in Hürthle cell carcinoma. Thyroid. 2019 Mar 08;: Authors: Ganly I, McFadden DG Abstract Hürthle cell tumors (HCT), including Hürthle cell adenomas (HCA) and Hürthle cell carcinomas (HCC) arise in the thyroid gland and are defined in part by an accumulation of mitochondria. These neoplasms were long considered a subtype of follicular neoplasm, although HCT is now generally considered a distinct entity. HCTs exhibit overlapping but distinct clinical features compared to follicular tumors, and several studies have demonstrated that HCTs harbor distinct genomic alterations compared to other forms of thyroid cancer. Two studies recently reported the most complete characterization of the HCC genome to date (1, 2). These studies assessed complementary cohorts of HCC specimens. The study by Ganly et al. (1) consisted of a large panel of primary HCC, including 32 widely-invasive and 24 minimally-invasive primary tumors. Exome and RNA sequencing of material isolated from fresh frozen tumor specimens was performed. The study by Gopal and Kübler et al. (2) utilized exome and targeted sequencing to characterize the nuclear and mitochondrial genomes of 32 primary tumors and 38 resected regional and distant metastases using DNA isolated from formalin-fixed paraffin-embedded (FFPE) tissues. Here, we briefly review HCC in the context of these studies. PMID: 30848171 [PubMed - as supplied by publisher]
