Roche's New Test for B-cell Lymphoma Diagnosis

In a significant leap forward in the field of hematopathology, Roche has announced the FDA clearance of its new in-situ hybridization (ISH) test, the VENTANA Kappa and Lambda Dual ISH mRNA Probe Cocktail. This innovative diagnostic tool is specifically designed to assist healthcare professionals in accurately distinguishing between B-cell malignancies and normal immune responses. Given that B-cell lymphomas comprise approximately 85% of all non-Hodgkin lymphoma (NHL) cases, which rank amongst the most prevalent cancers in the U.S., this development is particularly critical.

On January 13, 2025, Roche revealed that its new test, which has also received CE Mark approval in June 2024, is the first of its kind clinically approved to detect a wide array of B-cell lymphoma subtypes. The test enhances the diagnostic process, facilitating faster access to tailored treatment options for patients experiencing symptoms such as swollen lymph nodes, fever, fatigue, and more.

Importance of Accurate Diagnosis

The differentiating capability of the VENTANA Kappa and Lambda Dual ISH test is crucial, as symptoms of B-cell lymphoma can often mimic those of common infections. Jill German, Head of Pathology Lab at Roche Diagnostics, emphasized the importance of this new tool, stating, "Accurately differentiating lymphoma from an infection is critical in ensuring accurate and timely diagnosis. This reduces the need for multiple samples, promotes patient certainty, and speeds up access to necessary treatments."

By yielding the ability to evaluate over 60 B-cell lymphoma subtypes and plasma cell neoplasms within a single tissue slide, this assay allows pathologists to work with smaller biopsies, minimizing the need for fresh samples. This is especially beneficial in cases where lymphoma was not initially suspected.

How the Test Works

The VENTANA Kappa and Lambda Dual ISH mRNA Probe Cocktail is a qualitative assay that detects the expression of kappa and lambda immunoglobulin light chains within formalin-fixed paraffin embedded (FFPE) human hematolymphoid specimens. It acts as a supplementary tool when initial biopsies yield inconclusive results. The concurrent assessment of these markers on a single slide aids in distinguishing between reactive processes and true cases of B-cell lymphoma and plasma cell neoplasms.

Despite its advanced capabilities, the VENTANA Kappa and Lambda assay is not intended to operate in isolation. Each test result must be interpreted by a qualified pathologist, considering the patient's broader clinical history alongside other diagnostic analyses.
