What is DNA OncoNex ?

DNAOncoNex is a comprehensive targeted Next Generation Sequencing (NGS) assay for 70 genes associated with Thyroid cancer. NGS assay offers identification of numerous novel genetic aberrations and associated potential therapeutic targets in many cancers.

• Offers insights into the molecular underpinnings of the associated tumour mutation genes.
• With targeted therapies becoming the new standard of care in oncology, this NGS-driven diagnostics approach provides the choice of therapy to optimize patient outcomes in the future.

Why NGS for Thyroid Cancer ?

Thyroid cancer came to the 11th place of most common cancer worldwide and 5th in adult women, ranking first among endocrine malignancies

Papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC) known as differentiated thyroid carcinoma (DTC), contribute to more than 95% thyroid malignancies

According to Surveillance, Epidemiology, and End Results (SEER) data, 89.9% of patients diagnosed with thyroid cancers have papillary thyroid carcinoma (PTC), 4.5% follicular thyroid carcinoma (FTC), 1.5% Hurthle-cell carcinoma, and 0.8% anaplastic thyroid carcinoma (ATC).

• NGS offers diagnostic improvements for fine needle aspiration (FNA) cytology of thyroid with indeterminate features. It also contributes to patient management, providing risk stratification of patients based on the risk of malignancy.
• Mutations in Telomerase Reverse Transcriptase (TERT) are very common in thyroid cancers, from 22% to 23% in papillary thyroid carcinoma( PTC) to over 50% in poorly differentiated thyroid carcinomas (PDTC) and anaplastic thyroid carcinoma (ATCs).
• The BRAF V600E mutation is the most common genetic mutation detected in patients with PTC and occurs in approximately 45% of patient.
• NGS enables massively parallel sequencing for a large number of genes with accurate reads while being relatively inexpensive.
