-- The VENTANA MMR IHC Panel1 helps differentiate between sporadic colorectal cancer and probable Lynch syndrome, a hereditary form of colorectal cancer 

-- Lynch syndrome results in a 50 to 80 percent lifetime risk of developing colorectal cancer 

 -- Identification of probable Lynch syndrome allows clinicians to recommend additional testing of at-risk family members, with the goal of reducing disease and death

TUCSON, Arizona, Jan. 16, 2018 /PRNewswire/ -- Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced the launch of the CE-marked VENTANA MMR IHC Panel, which provides clinicians with a comprehensive group of immunohistochemistry (IHC) tests for patients diagnosed with colorectal cancer. The tests detect certain proteins associated with a DNA repair mechanism called mismatch repair (MMR), and aid in differentiating between sporadic colorectal cancer and probable Lynch syndrome, a hereditary form of colorectal cancer. About 3 percent of colorectal cancers are associated with Lynch syndrome.2

Lynch syndrome results in a 50 to 80 percent lifetime risk of developing colorectal cancer,3,4 making it important to identify the syndrome in colorectal cancer patients and at-risk family members. Identification of the syndrome may result in early detection and possible cancer prevention among those with the inherited mutation.5

The global burden of colorectal cancer is expected to increase by 60 percent to more than 2.2 million new cases and 1.1 million deaths by 2030.6 Increasingly, guidelines, including those from the National Institute for Health and Care Excellence (NICE), are recommending universal screening of all newly diagnosed colorectal cancers for Lynch syndrome. 

"This testing impacts not just the patient, but family members who may benefit from further genetic testing and advanced monitoring to detect colorectal cancer at its earlier stages, when it is more treatable," said Ann Costello, Head of Roche Tissue Diagnostics. "The VENTANA MMR IHC Panel provides clinicians with an additional tool to perform universal tumor screening for probable Lynch syndrome as recommended by medical guidelines."

The VENTANA MMR IHC Panel includes four assays that target MMR proteins MLH1, PMS2, MSH2 and MSH6, as well as the VENTANA BRAF V600E (VE1) assay. It is available for use on the BenchMark GX, XT and ULTRA instruments.

About the VENTANA MMR IHC Panel

The CE-marked VENTANA MMR IHC Panel consists of VENTANA anti-MLH1 (M1), VENTANA anti-PMS2 (A16-4), VENTANA anti-MSH2 (G219-1129), VENTANA anti-MSH6 (SP93) antibodies, for patients diagnosed with colorectal cancers for the detection of mismatch repair protein deficiency as an aid in the identification of probable Lynch syndrome, and VENTANA BRAF V600E (VE1) antibody as an aid to differentiate between sporadic colorectal cancer and probable Lynch syndrome.

The inclusion of the VENTANA BRAF V600E (VE1) antibody helps refine the number of patients who may receive additional testing for Lynch syndrome by aiding in the differentiation between sporadic colorectal cancer and probable Lynch syndrome in the absence of MLH1 protein expression.

The ready-to-use VENTANA MMR IHC Panel is optimized for use with the OptiView DAB IHC Detection Kit, OptiView Amplification Kit and ancillaries on the fully-automated BenchMark GX, XT and ULTRA instruments.
