The t(11;14)(q13;q32) translocation and its molecular counterpart bcl-1 rearrangement are highly characteristic of mantle cell lymphomas (MCLs). Most of these translocations occur at the major translocation cluster (MTC) in a tight area that makes this rearrangement identifiable by the polymerase chain reaction (PCR). In this study, the specificity and sensitivity of the PCR technique in the identification of bcl-1 rearrangement and its suitability to amplify the t(11;14) MTC in fixed, paraffin-embedded tissues were analyzed. Genomic DNA was obtained from 21 MCLs and 1 chronic lymphocytic leukemia (CLL) with the t(11;14) translocation. The bcl-1 rearrangement was studied by Southern blot with the MTC, p94PS, and PRAD-1 probes. Polymerase chain reaction was performed using a JH consensus primer and specific primers for chromosome II in the MTC region. bcl-1 rearrangement was identified by Southern blot in the MTC in nine (43%) MCLs and in the p94PS region in the CLL. Polymerase chain reaction analysis of genomic DNA showed that the nine MCLs with MTC rearrangement also had an amplifiable band of the expected size (100%). No amplifiable products were detected in the negative MCLs or in the CLL. The specificity of the PCR products was confirmed by hybridization with an internal MTC oligonucleotide probe. Amplifiable DNA was obtained from the paraffin blocks of 7 cases with MTC rearrangement and 11 negative tumors. bcl-1 rearrangement was detected in this DNA of 6 positive MCLs (86%) by PCR and in none of the negative cases. In conclusion, this study demonstrates that the PCR technique is highly sensitive and specific for the detection of the bcl-1 rearrangement at the MTC. It can be used with both high molecular weight DNA and DNA obtained from formalin-fixed, paraffin-embedded tissues.
