DetermaRxTM is a treatment stratification test to identify patients with stage I and IIA non-squamous NSCLC who may benefit from adjuvant chemotherapy.1


Confident treatment decisions in NSCLC

~ 40,000

patients are diagnosed with early-stage non-small cell lung cancer (NSCLC) each year.2


of early-stage patients will not survive despite complete surgical resection.3

We need a

better way

to understand which patients may benefit from chemotherapy.

Introduction to DetermaRx


Identify your patients who may benefit from chemotherapy


Order DetermaRx for your patient with stage I or IIA non-squamous NSCLC undergoing resection.


We analyze the molecular signature of your patient’s tumor tissue to stratify your patient’s risk.


Make informed treatment decisions for your patient following surgery.

  • DetermaRx is a 14-gene molecular stratification test that has been validated in two independent cohorts with close to 1400 patients.4
  • DetermaRx outperformed NCCN criteria in identifying patients at high risk for mortality from stage IA, IB, and IIA non-squamous NSCLC.4
  • Patients identified by DetermaRx as high-risk* and who were treated with adjuvant platinum chemotherapy had 91.7% 5-year disease-free survival compared to 48.9% 5-year DFS for high-risk patients who did not receive chemotherapy.1
  • In a study of physician practices, DetermaRx results led to a change in treatment recommendation for 30% of patients.5

*Test identified intermediate- and high-risk patients were grouped together in this analysis and designated as molecular high-risk.
