Lymphoplasmacytic lymphoma (LPL) is characterized by t(9;14)(p13;q32) in 50% of patients who lack paraproteinemia. Waldenström macroglobulinemia (WM), which has an immunoglobulin M (IgM) paraproteinemia, is classified as an LPL. Rare reports have suggested that WM sometimes is associated with 14q23 translocations, deletions of 6q, and t(11;18)(q21;q21). We tested for these abnormalities in the clonal cells of WM patients. We selected patients with clinicopathologic diagnosis of WM (all had IgM levels greater than 1.5 g/dL). Southern blot assay was used to detect legitimate and illegitimate IgH switch rearrangements. In addition to conventional cytogenetic (CC) and multicolor metaphase fluorescence in situ hybridization (M-FISH) analyses, we used interphase FISH to screen for t(9;14)(p13;q32) and other IgH translocations, t(11;18)(q21;q21), and 6q21 deletions. Genomic stability was also assessed using chromosome enumeration probes for chromosomes 7, 9, 11, 12, 15, and 17 in 15 patients. There was no evidence of either legitimate or illegitimate IgH rearrangements by Southern blot assay (n = 12). CC (n = 37), M-FISH (n = 5), and interphase FISH (n = 42) failed to identify IgH or t(11;18) translocations. Although tumor cells from most patients were diploid for the chromosomes studied, deletions of 6q21 were observed in 42% of patients. In contrast to LPL tumors that are not associated with paraproteinemia and that have frequent t(9;14)(p13;q32) translocations, IgH translocations are not found in WM, a form of LPL tumor distinguished by IgM paraproteinemia. However, WM tumor cells, which appear to be diploid or near diploid, often have deletions of 6q21.

We describe the development and application of a sensitive high-resolution fluorescence alkaline phosphatase (APase)-Fast Red immunocytochemical (ICC) staining method in combination with fluorescence in situ hybridization (ISH) and bromodeoxyuridine (BrdU) detection. The high fluorescence intensity, accurate localization, and advantageous slow-fading properties make the APase-Fast Red reaction a valuable tool for detection of antigens or specific DNA probes in biological cell preparations. Since the enzyme precipitate proved to be resistant to enzymatic pre-treatment steps and stable during the entire ISH procedure, APase-Fast Red immunostaining could be combined with subsequent visualization of DNA target sequences by fluorescence ISH. The lung cancer cell lines NCI-H82 and EPLC 65 were used as a model system for simultaneous detection of cell proteins, such as the neural cell adhesion molecule (N-CAM), cytokeratin filaments, lamin or the Ki67 antigen (Ki67-Ag), and centromere-specific DNA probes for human chromosomes 1, 7, or 17. In addition, the combined ICC/ISH procedure could be extended with the immunodetection of BrdU incorporated by tumor cells in S-phase. As a consequence, a combined ICC/ISH/BrdU detection procedure is now available that enables analysis of relatively complex tumor populations on the basis of different ICC and genetic markers as well as proliferative activity.

This strategy uses two fluorophore-labeled signal probes to generate a supersandwich product, which in turn generates numerous signal probes located at the target mRNA position, resulting in thein situfluorescence signal amplification.
