You Spoke. We Listened.

Introducing the VENTANA HER2 Dual ISH Probe Cocktail assay, part of the Roche Tissue Diagnostics Breast Cancer IHC/ISH Portfolio. Based on input from pathologists and lab professionals like you, Roche created an enhanced assay with brightfield technology for high quality in-house testing so your lab has the ability to deliver results on the first read. And that benefits everybody, from your lab team to the clinicians and patients who rely on you for results. Because the best ideas for improving assays are the ones that come from you.

Built for quality. Built for reliability. Built for you.

 

US FDA Approved VENTANA HER2 Dual ISH DNA Probe Cocktail assay

HER2-Dual-ISH

Optimized with new oligo probes, the VENTANA HER2 Dual ISH assay delivers clear, confident results

The new VENTANA HER2 Dual ISH Probe Cocktail is a fully automated, ready-to-use brightfield solution for determining HER2 gene amplification. VENTANA HER2 Dual ISH helps identify breast cancer patients eligible for treatment with HERCEPTIN® (trastuzumab).

The VENTANA HER2 Dual ISH assay is easily interpreted using brightfield microscopy2 which has proven concordance with FISH1 enabling every lab the ability to run testing in-house that allows for faster results to the oncologist and their patient.

To evaluate the clinical sensitivity and specificity of the VENTANA HER2 Dual ISH DNA Probe Cocktail assay in determination of HER2 gene status in breast carcinoma, a multi-site method comparison study was performed using the Abbott/Vysis PathVysion HER-2 FISH Kit as the comparator device. Approximately 600 individual breast cancer cases were stained in three central laboratories.1

Table 1: Summary of negative, positive, and overall agreement rates for VENTANA HER2 Dual ISH DNA Probe Cocktail and Abbott/Vysis PathVysion HER-2 DNA Probe Kit. The overall percent agreement between the VENTANA HER2 Dual ISH DNA Probe Cocktail and Abbott/Vysis PathVysion HER-2 DNA Probe Kit is 92.7%.

Why brightfield is better

  • No need for fluorescent microscope/oil and darkroom
  • Fits into pathologist’s regular workflow at brightfield scope
  • Can be read alongside/at same time as H&E and other breast panel markers on the same case for easy comparison and correlation of findings
  • No interference from tissue auto fluorescence or tissue marking dyes
  • Produces archivable results
  • Signals do not fade over time

 

 

Indicated as an aid in the assessment of patients for whom HERCEPTIN (trastuzumab) in being considered

Multiple guidelines, including NCCN4 and CAP/ASCO3, recommend the evaluation of human epidermal growth factor receptor 2 (HER2) protein expression in breast cancer.
