Neurotrophic tyrosine receptor kinase gene fusions ( NTRK ) are oncogenic drivers present at a low frequency in most tumour types (<5%), and at a higher frequency (>80%) in a small number of rare tumours (e.g., infantile fibrosarcoma [IFS]) and considered mutually exclusive with other com …
Test Description The NTRK NGS Fusion Panel is an RNA-based next-generation sequencing panel that detects translocations and fusions of the Neurotrophic Tropomyosin-Related Kinase (NTRK) genes NTRK1, NTRK2, and NTRK3 with known and novel fusion partners. Point mutations in select exons of these three genes are also detected.
The overall high success rate demonstrates that FISH‐ and tNGS‐based NTRK testing can be well established in a routine Testing for all relevant patients will be rolled out as soon as capacity is created in the genetic testing service in the NHS through reduced need for coronavirus tests. Molecular testing for NTRK gene fusions is key to identifying those patients who are most likely to benefit from the treatment and therefore becomes a first and essential element of treatment planning. Le fusioni del gene NTRK sono associate a diversi tipi di tumore 1,2. Le fusioni del gene NTRK sono associate a diversi tumori solidi e neoplasie ematologiche 1-3 e generalmente sono mutualmente esclusive rispetto ad altre alterazioni genomiche driver.
This test assesses for fusions involving the NTRK1, NTRK2, and NTRK3 genes. The results of this test can be useful in guiding treatment of individuals with advanced solid tumors. The challenges of NTRK gene fusion detection Detecting NTRK gene fusions is challenging due to the many considerations that must be taken into account when choosing a testing methodology. Review the challenges with Dr Michelle Shiller. NTRK Fusion Testing & Diagnosis Biomarker ‘genomic testing’ offers a gateway to better understand our type of cancer.
NTRK Gene Fusion testing is a strongly recommended component of comprehensive genomic profiling of newly diagnosed solid tumors. 1,3 NCCN and other expert consensus recommendations indicate that NTRK gene fusion testing should be performed as part of a broad, panel-based approach. 1
For me, the most important conclusion is that it is critical for clinicians and cancer treatment centers to invest in NGS approaches now or at a minimum have easy access to clinical labs that do provide this testing. Given NTRK gene fusions are rare, the key issues with testing are how to identify all patients with TRK fusion cancer in the most time-, cost-, and tissue-efficient manner.
NTRK is emerging as an actionable biomarker and oncogenic driver across a wide High quality molecular testing is needed to uncover NTRK fusion+ cancer 1
Well-designed targeted RNA next-generation sequencing (NGS) is considered the most reliable method to test for abnormalities involving NTRK1, NTRK2, and NTRK3 genes, including fusion, point mutation, and splicing.
The assay was designed to detect the most common NTRK gene fusions and novel gene fusion partners in the targeted gene regions.

1. Advanced testing is needed to uncover NTRK fusion + cancer; Diagnostic testing should detect NTRK 1,2,3 fusion genes and be validated with appropriate reference standards. 1 Appendix and Cerebelum tissue can be used for controls to assess for the presence of NTRK fusion proteins through IHC. NTRK Gene Fusion testing is a strongly recommended component of comprehensive genomic profiling of newly diagnosed solid tumors. 1,3 NCCN and other expert consensus recommendations indicate that NTRK gene fusion testing should be performed as part of a broad, panel-based approach.
We briefly discuss the pros and cons of various methods, focusing primarily on immunohistochemistry (IHC) and next generation sequencing (NGS), as these are the focus of the in the CANTRK Ring Study [ 31 ]. Why NTRK fusion testing is becoming important. Different methods of NTRK fusion detection, including their pros and cons based on real data from lung cancer testing. How developments in precision oncology are changing not only cancer care, but also the way we should approach biomarker testing in our laboratories.

Forskning visar att NTRK gener kan fusionera med andra gener och då skapa ett TRK Endast speciella test kan med säkerhet upptäcka TRK fusionscancer.
Based on the probability of the tumour harbouring an NTRK gene fusion, we also suggest a tumour-agnostic consensus for NTRK gene fusion testing and treatment. We recommend considering a TRK inhibitor in all patients with TRK fusion cancer with no other effective treatment options. NTRK gene fusions have been found in more than 25 different cancer types, including, sarcoma, non-small cell lung cancer (NSCLC), salivary cancer, secretory breast cancer, and papillary thyroid cancer. If you or a loved one has cancer, talk to your doctor about testing for the NTRK gene fusion.
