Go beyond KRAS - The All-RAS-Panel

Our understanding of the important RAS mutations in CRC has evolved over time. In 2008, KRAS mutations in Codons12 and 13 were the only mutations considered important in determining the appropriate therapy for metastatic colorectal cancer patients. Since that time, recent clinical studies have shown that the detection of additional mutations in KRAS and NRAS codons should also be considered in determining patient eligibility for targeted anti‐EGFR therapies.

The OncoBEAM™ RAS qualitative digital PCR based test is intended for the detection of gene mutations in KRAS codons 12, 13, 59, 61, 117, 146 and NRAS codons 12, 13, 59, 61, 117, 146 extracted from Stage IV colorectal cancer patient plasma. The kit is intended to aid the clinician in determining potential benefit of anti-epidermal growth factor receptor (EGFR) therapy to colorectal cancer patients.

Enhanced Clinical Value of OncoBEAM™ RAS Testing

Enhanced Clinical Value of OncoBEAM™ RAS Testing

A meta‐analysis of randomized, controlled trials (RCT) was conducted on the prevalence of RAS mutations in mCRC. Nine RCTs comprising a total of almost 6,000 participants were evaluated for both KRAS Exon 2 and new KRAS and NRAS mutations. The conclusion of the analysis is that patients with tumors exhibiting one of the new RAS mutations are unlikely to significantly benefit from anti‐EGFR therapy in mCRC.1
In 2015, guidelines were updated to recommend expanded RAS testing prior to use of an anti‐EGFR treatment.2-4 The inclusion of low frequency KRAS and NRAS mutations in Exons 2, 3 and 4 formed the basis for our comprehensive OncoBEAM™ RAS CRC kit.

The test cannot differentiate between somatic and germline mutations without the analysis of matched normal cells. False negative and positive results may occur for the following reasons:

  1. Incorrect handling of blood samples or plasma samples (e.g. prolonged storage)
  2. Rare polymorphisms within the region of interest
  3. Heterogeneity of specimen
  4. High mutant samples might cause false positive results in neighboring samples. Use caution during workflow procedure and reanalyze test results for confirmation in case of doubt.

The test is not recommended for use for patients undergoing therapy, as low tumor burden may exist which may yield inaccurate results. BEAMing technology is a highly sensitive detection procedure that uses polymerase chain reaction (PCR), therefore use caution to avoid contamination of samples and reaction mixes by external sources of DNA and/or PCR product in the test environment and the DNA in the positive control.

Other mutations within the gene of interest or other genes are not analyzed with this test.
