Veracyte Announces Publication Highlighting Afirma GSC’s Ability to Rule Out Cancer in Challenging Thyroid Nodule Subtype
SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Apr 8, 2019--Veracyte, Inc. announced today that a new study published online in BMC Systems Biology showcases the development of the Afirma ® Genomic Sequencing Classifier (GSC) and its ability to distinguish benign from likely-cancerous Hürthle cells, a common, but difficult-to-diagnose thyroid nodule subtype. The Afirma GSC was developed using Veracyte’s novel RNA whole-transcriptome sequencing and machine learning platform. Most Hürthle cell cases yield inconclusive cytopathology results and, prior to Veracyte’s next-generation genomic test, most of these patients typically required surgery to rule out thyroid cancer.
“While most Hürthle cells in patients with indeterminate thyroid nodules are benign, patients with this thyroid nodule subtype have historically been recommended for surgery because of the possibility of cancer,” said Richard T. Kloos, M.D., senior medical director – endocrinology, at Veracyte. “Our novel science and technology platform enables the Afirma GSC to distinguish benign Hürthle cells and thus help rule out the need for surgery for many of these patients.”
The new paper details the Afirma GSC’s development and includes previously reported clinical validation findings showing that the Afirma GSC’s ability to identify benign Hürthle-cell nodules increased by nearly five-fold compared to Veracyte’s original Afirma Gene Expression Classifier (GEC). The next-generation test also maintains the flagship Afirma test’s high sensitivity (91 percent), while identifying 30 percent more benign nodules (68 percent specificity) – regardless of thyroid subtype.
“This new paper supports the real-world results that we have observed in our practice since we began using the Afirma GSC in August 2017,” said R. Mack Harrell, M.D., of the Memorial Center for Integrative Endocrine Surgery in Boca Raton, Fla. “We recently reported that, among Hürthle-cell dominant thyroid nodules, which comprise about 20 percent of all indeterminate nodules in our practice, the Afirma GSC has significantly increased the number of benign nodules that we’ve identified. Using the Afirma GSC test allows us to send 45 percent fewer patients to surgery, compared to the original Afirma GEC test, for an absolute reduction in surgeries of 25 percent. This is great news for our patients and for the healthcare system.”
The Afirma Genomic Sequencing Classifier (GSC) and Xpression Atlas provide physicians with a comprehensive solution for a complex landscape in thyroid nodule diagnosis. The Afirma GSC was developed with RNA whole-transcriptome sequencing and machine learning and helps identify patients with benign thyroid nodules among those with indeterminate cytopathology results in order to help patients avoid unnecessary diagnostic thyroid surgery. The Afirma Xpression Atlas provides physicians with genomic alteration content from the same fine needle aspiration samples that are used in Afirma GSC testing and may help physicians decide with greater confidence on the surgical or therapeutic pathway for their patients. The Afirma Xpression Atlas includes 761 DNA variants and 130 RNA fusion partners in over 500 genes that are associated with thyroid cancer.
