OncoBEAM™ for Lung Cancer

Obtain an accurate, real-time snapshot of mutations before initiating treatment

No tissue means fewer delays and highly accurate results

Analyzing mutations in tumor tissue may have considerable drawbacks. Not only is there a risk of complications, but it can take weeks to get results. Numerous clinical trials show that tissue is insufficient for molecular testing in up to 50% of cases.1

Thanks to our highly-sensitive BEAMing technology, a liquid biopsy with OncoBEAM™ requires only a simple blood draw to access tumor DNA and provide a real-time view of a tumor’s mutation status in 5 to 7 days.

OncoBEAM™ assays for NSCLC provide results in just 5 to 7 days from our CLIA-certified laboratory, helping doctors to make faster treatment decisions for patients.

Multiple non-small cell lung cancer mutations, one solution

Clinical practice guidelines for the treatment of non-small cell lung cancer (NSCLSC) recommend a combination of EGFR, KRAS, and BRAF testing to provide a comprehensive mutational analysis.2-5 OncoBEAM™ tests for this trifecta of mutations.

OncoBEAM™ Lung1: EGFR

Sensitizing Mutations: Del 19, L858R, L861Q
Resistant Mutations: T790M, C797S


Sensitizing Mutations: Del 19, L858R, L861Q
Resistant Mutations: T790M, C797S
KRAS: Codons 12, 13 ,and 61

EGFR mutations and TKI therapy

NSCLC tumors with sensitizing EGFR mutations have increased sensitivity to tyrosine kinase inhibitors (TKIs). Patients who initially respond to TKI therapy frequently relapse, with 60% of those on TKIs developing resistance due to the EGFR T790M mutation.4-5

OncoBEAM™ EGFR can identify the T790M mutation in patients who have progressed on first-line TKI therapy, delivering rapid results and avoiding the need for a repeat tissue biopsy.6

60% of patients on EGFR TKI therapy develop resistance due to the EGFR T790M mutation.7

KRAS: the most prevalent NSCLC mutation

KRAS mutations occur in 25% of NSCLC cases.8 Independent of therapy, KRAS mutations can indicate poor survival rates compared to tumors without KRAS mutations.

OncoBEAM™ KRAS can identify multiple KRAS mutations, providing a more complete picture of a patient’s condition to rapidly inform critical therapy decisions.


BRAF testing precedes first-line therapy

BRAF mutations are detected in approximately 3% of patients with NSCLC.8 The 2017 NCCN guidelines now include BRAF V600E mutation testing for all newly diagnosed patients in order to inform appropriate administration of first-line therapy, which now includes BRAF targeted therapies.2

OncoBEAM™ BRAF tests for the BRAF V600E mutation, helping doctors to decide whether to initiate first-line therapy as soon as possible.


Case scenario

Avoiding a repeat biopsy

A 64-year-old woman was diagnosed with stage IV NSCLC. Her tumor was EGFR positive. She responded well to EGFR TKI therapy with substantial tumor shrinkage and disease stabilization.

Following initial treatment

  • CT-scan showed disease progression in multiple sites, suggesting 1st line EGFR TKI resistance
  • Repeat biopsy was considered to evaluate for the presence of a T790M mutation
  • Patient was hesitant to undergo another tissue biopsy

The OncoBEAM™ solution

OncoBEAM™ EGFR can test for the EGFR T790M mutation amongst multiple sites of disease with a simple blood draw, avoiding the need for an additional tissue biopsy.


Can OncoBEAM™ be used with multiple NSCLC tumor mutation biomarkers?

Yes. Clinically actionable multigene detection panels are available to assess the mutational status of a tumor.

Does OncoBEAM™ detect all gene mutations like sequencing?

Not quite. OncoBEAM™ detects mutations in hot spot locations in clinically relevant genes that are indicated in clinical practice guidelines for patient care.

Is it possible to use the plasma OncoBEAM™ assay to monitor NSCLC tumor dynamics?

Yes. Plasma mutation status correlates well with response to therapy and there is growing evidence that it can be used to understand tumor activity and disease progression.9, 10

Can BEAMing be used for all cancer stages?

OncoBEAM™ can be used for most cancers where the tumor has accessed the circulatory system and released ctDNA, Multiple tumor types have been shown to shed ctDNA including: lung, colorectal, pancreatic, prostate, breast, melanoma. Certain cancers, such as gliomas, have ctDNA levels that are too low to detect.11

How are OncoBEAM™ tests billed and reimbursed?

Sysmex Inostics accepts all insurance plans, but OncoBEAM™ tests are currently not in-network with most carriers. We are working to become in-network with payors. Sysmex Inostics directly bills insurance or Medicare and patients are not responsible for any balance that is not covered by insurance or Medicare. Deductibles may apply if applicable. Sysmex Inostics does not accept uninsured or Medicaid patients at this time.
