t(14;18) status was determined using Vysis LSI IGH/BCL2 Dual Color, Dual Fusion FISH assays. PCR assays used a Jh consensus primer, an MBR1 primer corresponding to the BCL2 major breakpoint region (MBR), and a second primer 360 base pairs upstream of MBR1. Assays were run on archival paraffin-embedded tumor sections.
Unreadable FISH assays could not be scored because of inadequate sample or FISH signal strength.
Unreadable PCR assays were negative for the human hemoglobin beta (HBB) internal control and t(14;18).
