December 2020 New molecular panels for theranostic and/or prognostic purposes enabling several genes involved in solid tumours to be analysed simultaneously by NGS.
For the therapeutic management of certain solid tumours, cytogenetic (FISH) and molecular biology techniques are indispensable – therefore, the term “companion test” for targeted therapy is commonly used. For the past ten years, these molecular tests have been offered at Eurofins Biomnis in an isolated test format (e.g. EGFR, KRAS, NRAS or BRAF).
Therapeutic management in the field of solid oncology is progressing at lightening speed and requires providing the clinician with increasingly precise and personalised information: prognostic value of a mutation, sensitivity or resistance associated with a mutation for a targeted therapy and for a given type of tumour, or the identification of mutations of acquired resistance secondary to a targeted treatment.
Eurofins Biomnis’ new global offer in solid oncology responds to this demand and in particular the “NGS – Solid Tumours” offer.
The laboratory now offers various gene panels analysed by high-throughput sequencing (NGS). This technique allows the molecular characterisation of tumours by simultaneously analysing several genes (from 3 to 24) involved in carcinogenesis.
These panels are dedicated to each organ (e.g. lung, colon, etc.) to facilitate their prescription and extended NGS panels are also available to analyse emerging markers of targeted therapies (monoclonal antibodies and tyrosine kinase inhibitors) or secondary molecular markers of resistance.
Complementary molecular tests are also available to complete this NGS offer: MSI test, targeted FISH test, etc.
This “NGS Solid Tumours” offer is an extension of the “NGS Haematological Malignancies” offer performed by the laboratory since April 2019:
| Organ / Disease | Panel | Test Code | Turnaround time |
| LUNG | LUNG Panel 1 (4 genes) EGFR – BRAF – MET- KRAS | POUM1 | 10 days |
| LUNG Panel 2 (19 genes) AKT1 – ALK – BRAF – DDR2 – EGFR – HER2 – FGFR1 – FGFR2 – FGFR3 – KIT – KRAS – MAP2K1 – MET – NRAS – PDGFRA – PIK3CA – PTEN – STK11 – TP53 | POUM2 | 10 days | |
| COLORECTAL | COLO-RECTAL Panel 1 (3 genes) KRAS – NRAS – BRAF | COLO1 | 10 days |
| COLORECTAL Panel 2 (21 genes) AKT1 – ALK – BRAF – CTNNB1 – EGFR – HER2 – FBXW7 – FGFR1 – FGFR2 – FGFR3 – KIT – KRAS – MAP2K1 – MET – NRAS – PDGFRA – PIK3CA – PTEN – SMAD4 – STK11 – TP53 | COLO2 | 10 days | |
| GIST | GIST Panel (3 genes) KIT – PDGFRA – BRAF | GIST | 10 days |
| MELANOMA | MELANOMA Panel (3 genes) BRAF- NRAS – KIT | MELA | 10 days |
| PAN ORGANE | PAN ORGAN Panel (24 genes) AKT1 – ALK – BRAF – CTNNB1 – DDR2 – EGFR – HER2 – HER4 – FBXW7 – FGFR1 – FGFR2 – FGFR3 – KIT – KRAS – MAP2K1- MET – NOTCH1 – NRAS – PDGFRA – PIK3CA – PTEN – SMAD4 – STK11 – TP53 | PAN | 10 days |
These molecular techniques are interpreted by a clinical pathologist in close collaboration with our anatomical pathologists.
The above-mentioned gene panels are made from DNA extracted from tumour tissue. It should be noted that the quality of interpretation of these tests depends directly on the pre-analytical conditions of the sample (ischaemia time, type of fixative and fixation time), the reagents used and the robustness of the molecular biology technique chosen.
