The clonal determination of B-cell lymphoproliferative disorders by immunoglobulin heavy chain (IgH) rearrangement by polymerase chain reaction (PCR) is widely used. However, few attempts have been made to detect immunoglobulin κ light chain (Igκ) gene rearrangement using PCR. We studied 145 cases of B-cell neoplasms, along with 58 atypical and 18 reactive lymphoproliferative disorders, using newly designed degenerate oligoprimers recognizing the framework 3 (FR3κ) and the joint (Jκ. regions of the Igκ gene. PCR products were analyzed on nondenaturing polyacrylamide gel (ndPAGE). Clonal B-cell determination was further investigated using IgH rearrangement and t(11:14) or t(14:18). By combining these methods, we detected either clonality or translocation in 117 of 137 cases (85%) in mature B-cell neoplasms. The additional analysis of Igκ rearrangement improved sensitivity from 66% to 85%. To investigate whether the Ig gene configuration could be characterized using Igκ PCR in B-cell neoplasms showing severe breakdown of genomic DNA, 18 selected cases were analyzed. Successful amplification was detected in 72% of the cases using either FR3/2-JH and/or FR3Jκ oligoprimers. Finally, clonality was detected in 21 of 58 atypical B-cell proliferations, and among them, the atypical marginal cell (54%) and atypical large cell (50%) proliferations showed the highest frequency of clonal immunoglobulin gene products. We concluded that PCR/ndPAGE analysis of Igκ is a sensitive, rapid, and efficient method for assessing clonality in conjunction with IgH and specific translocation analysis. This approach is particularly useful in the characterization of B-cell lymphoproliferative disorders in archival material with poor preservation of the genomic DNA.

This approach is particularly useful in the characterization of B-cell lymphoproliferative disorders in archival material with poor preservation of the genomic DNA. The characterization of immunoglobulin (Ig) gene rearrangement has become an important and crucial step in the diagnosis of B-cell lymphoid malignancies. The clonal rearrangements of Ig heavy chains (IgH) and Ig light chains (IgL) in B-cell disorders provide excellent markers for molecular analysis.1Korsmeyer SJ B-lymphoid neoplasms: immunoglobulin genes as molecular determinants of clonality, lineage, differentiation, and translocation.Adv Intern Med. 1988; 33: 1-15PubMed Google Scholar, 2Medeiros LJ Bagg A Cossman J Application of molecular genetics to the diagnosis of hematopoietic neoplasms.in: Knowles DM Williams and Wilkins, Baltimore1992: 263-298Google Scholar For the past 10 years, Southern blotting has been widely used to detect clonality.3van Dongen JJ Wolvers-Tettero IL Analysis of immunoglobulin and T cell receptor genes.

Furthermore, because small DNA fragments are the targets of PCR, this approach has been successfully applied in the study of formalin-fixed and paraffin-embedded tissue samples. Even in severely damaged archival material, PCR can still detect fragments smaller than 200 bp and identify clonal Ig gene products.8Trainor KJ Brisco MJ Story CJ Morley AA Monoclonality in B-lymphoproliferative disorders detected at the DNA level.Blood. 1990; 75: 2220-2222PubMed Google Scholar, 9Inghirami G Szabolcs MJ Yee HT Corradini P Cesarman E Knowles DM Detection of immunoglobulin gene rearrangement of B cell non-Hodgkin's lymphomas and leukemias in fresh, unfixed and formalin-fixed, paraffin-embedded tissue by polymerase chain reaction.Lab Invest. 1993; 68: 746-757PubMed Google Scholar Several groups have established PCR-based methodologies for the detection of IgH rearrangement.9Inghirami G Szabolcs MJ Yee HT Corradini P Cesarman E Knowles DM Detection of immunoglobulin gene rearrangement of B cell non-Hodgkin's lymphomas and leukemias in fresh, unfixed and formalin-fixed, paraffin-embedded tissue by polymerase chain reaction.Lab Invest. 1993; 68: 746-757PubMed Google Scholar, 10Yamada M Hudson S Tournay O et al.Detection of minimal disease in hematopoietic malignancies of the B-cell lineage by using third-complementarity-determining region (CDR-III)-specific probes.Proc Natl Acad Sci USA. 1989; 86: 5123-5127Crossref PubMed Scopus (283) Google Scholar, 11Deane M Norton JD Detection of immunoglobulin gene rearrangement in B lymphoid malignancies by polymerase chain reaction gene amplification.Br J Haematol. 1990; 74: 251-256Crossref PubMed Scopus (104) Google Scholar, 12Trainor KJ Brisco MJ Wan JH Neoh S Grist S Morley AA Gene rearrangement in B- and T-lymphoproliferative disease detected by the polymerase chain reaction.Blood. 1991; 78: 192-196PubMed Google Scholar, 13Segal GH T for clonality by polymerase chain reaction analysis.
