For patients with solid tumours,

Let testing be your guide

Every cancer is unique. Let’s treat it that way

Targeted therapies are being studied to advance treatment options for patients with actionable biomarkers – patients with gene fusions need high quality molecular testing to realise these opportunities.1,2 

To help patients with NTRK or ROS1 fusion+ cancer, we must first identify them. #PutCancerToTheTest 

NTRK fusion positive genes are emerging as actionable biomarkers and oncogenic drivers across a wide range of tumour types.1–6 NTRK fusion+ cancer currently has no known defining clinical or pathological features.1–3

Only high quality molecular testing such as next-generation sequencing (NGS) can confirm
NTRK fusion+ cancer.1

How NTRK fusions drive cancer

ROS1 gene fusions have proved to be key indicators for several cancers and are a validated therapeutic target in NSCLC.7,8  Up to 40% of patients with ROS1+ NSCLC also have CNS metastases at diagnosis.9–12

Only high quality molecular testing, such as FISH and NGS, can identify patients with actionable ROS1 positive gene fusions.13

How ROS1 fusions drive cancer

Knowing a patient’s biomarker profile can open up new targeted treatment options.14–16 High quality NGS helps you see beyond the tumour origin to exactly which mutations are driving that cancer.17

Precision medicine combines different treatment options, including traditional cancer therapies and emerging targeted therapies, with the aim of achieving the best possible outcome for the patient.18

A number of diagnostic options are available for the identification of gene fusions. However, not all are equally reliable.1,19–23

Only sensitive and specific tests can reliably detect NTRK and ROS1 gene fusions20,22,24
