Roche has received FDA clearance for its new Ventana diagnostic tool, the 'Ventana Kappa and Lambda Dual ISH mRNA Probe Cocktail,' designed to differentiate malignant B-cell tumors from other tumors. This test can identify around sixty subtypes of B lymphoma and plasma cell neoplasms from a single sample slide, aiding physicians in determining optimal treatment. B-cell lymphomas represent approximately 85% of non-Hodgkin's lymphomas, a prevalent cancer type in the U.S., with over 80,000 annual deaths.
