PG - 127-142 AB - The cytogenetic analysis of plasma cell myeloma (PCM) allows stratification of patients so that prognosis may be determined and appropriate therapeutic options can be discussed. Owing to the patchy nature of the disease in the bone marrow (BM), the low proliferative activity of plasma cells and the cryptic nature of some PCM-associated cytogenetic changes, karyotypic analysis in this disease should be augmented with targeted interphase fluorescence in situ hybridization (FISH). Immunofluorescent revelation of cytoplasmic immunoglobulin light chains, together with interphase FISH (cIg-FISH), allows the identification of plasma cells within a sample so that they may be scored preferentially. This is particularly useful in situations where there are only a small percentage of plasma cells in a sample. Where an underlying myeloid disease is suspected the cIg-FISH-negative cells can be scored separately. Two methods are provided in this chapter: the technique for cIg-FISH in fresh PCM BM samples and a procedure for use in fixed cytogenetics preparations.
