    Risk GroupCytogenetic FindingsDisease Characteristics
    FISH = fluorescencein situ hybridization.
    Standard riskHas any of the following cytogenetic findings: (1) no adverse FISH or cytogenetics, (2) hyperdiploidy, (3) t(11;14) by FISH, or (4) t(6;14) by FISH.These patients most often have (1) disease that expresses IgG kappa monoclonal gammopathies and (2) lytic bone lesions.
    High riskHas any of the following cytogenetic findings: (1) del 17p by FISH, (2) t(4;14) by FISH, (3) t(14;16) by FISH, (4) cytogenetic del 13, or (5) hypodiploidy.These patients have (1) disease that expresses IgA lambda monoclonal gammopathies (often) and (2) skeletal-related complications (less often).
