Three-pronged Centralized Molecular Analysis to Optimize Detection of

Status Active, not recruiting

Clinical Trial Summary

This multi-center study aims at NTRK fusion testing of all patients with advanced thyroid cancer (any histotype and regardless of stage). The primary objective of this study is to assess the frequency of NTRK fusions in thyroid cancer. The secondary objective of this study is to develop an effective tool (testing) strategy for the detection of NTRK fusions in thyroid tumors, comparing the diagnostic tecniques available (IHC, real-time PCR and NGS).

Clinical Trial Description

Thyroid cancer is the most common neoplasm of the endocrine system. Most thyroid carcinomas originate from the follicular epithelium and are distinguished in differentiated forms (DTC): papillary (PTC) and follicular (FTC) carcinomas. Both have a favorable prognosis and account for approximately 80% and 10% of all thyroid neoplasms, respectively. The undifferentiated form represented by the anaplastic thyroid carcinoma (ATC) is less frequent (about 2%) and represents one of the most aggressive human tumors with a survival that rarely exceeds 6-12 months. Medullary thyroid carcinoma (MTC), deriving from parafollicular C cells, is relatively rare (approximately 5%) and is associated with an intermediate prognosis between differentiated and poorly differentiated forms. As to the prevalence of NTRK lesions, many authoritative papers and reviews claim very high (up to 75%) NTRK fusion frequencies, particularly in the common PTC. However, an extensive PubMed analysis back to year 1990 does not provide convincing support for this claim.Several techniques for NTRK fusion diagnosis exist, including pan-Trk IHC, FISH, reverse transcription PCR, DNA-based next-generation sequencing (NGS), and RNA-based NGS. Each of these assays has unique features, advantages, and limitations, and familiarity with these assays is critical to appropriately screen for NTRK fusions. The aim of this study is to determine the frequency of NTRK fusions in advanced thyroid cancer patients and to compare the diagnostic tecniques available (IHC, real-time PCR and NGS). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
