PURPOSE: This laboratory study is analyzing chromosomes in patients with newly diagnosed multiple myeloma or other blood disease.
- Compare the frequency of deletion 13 as detected by fluorescence in situ hybridization (FISH) and conventional cytogenetics in patients with newly diagnosed multiple myeloma (MM) or other monoclonal gammopathies (MG).
- Examine the prognostic value of specific subsets of chromosome aberrations detected by conventional cytogenetics and FISH in relation to event-free and overall survival in these patients.
- Compare the prognostic value of cytogenetics and FISH with other MM and MG prognostic factors in these patients.
- Correlate the presence of cytogenetic and FISH features with clinical pathophysiological, cellular, or other molecular characteristics in these patients.
OUTLINE: Patients receive treatment as directed by the treatment clinical trial on which they are registered. Patients undergo bone marrow or blood sample collection periodically for conventional cytogenetic analysis and fluorescence in situ hybridization studies (FISH). Samples are analyzed for deleted 13q/monosomy 13 and chromosomal abnormalities.
PROJECTED ACCRUAL: A total of 500 patients will be accrued for this study.

Development and validation of a novel clinical fluorescence in situ hybridization assay to detect JAK2 and PD-L1 amplification: a fluorescence in situ hybridization assay for JAK2 and PD-L1 amplification.
The amplification of chromosome 9p24.1 encoding PD-L1, PD-L2, and JAK2 has been reported in multiple types of cancer and is associated with poor outcome, upregulation of PD-L1, and activation of the J...
A type of IN SITU HYBRIDIZATION in which target sequences are stained with fluorescent dye so their location and size can be determined using fluorescence microscopy. This staining is sufficiently distinct that the hybridization signal can be seen both in metaphase spreads and in interphase nuclei.
The simultaneous identification of all chromosomes from a cell by fluorescence in situ hybridization (IN SITU HYBRIDIZATION, FLUORESCENCE) with chromosome-specific florescent probes that are discerned by their different emission spectra.
MOLECULAR BIOLOGY techniques used in the diagnosis of disease. Included are such techniques as IN SITU HYBRIDIZATION of chromosomes for CYTOGENETIC ANALYSIS; OLIGONUCLEOTIDE ARRAY SEQUENCE ANALYSIS of gene expression patterns in disease states; identification of pathogenic organisms by analysis of species specific DNA sequences; and detection of mutations with POLYMERASE CHAIN REACTION.
