Defined as cytogenetic abnormalities that are not considered high risk (trisomies, t(11;14), t(6;14)), and/or R-ISS stage I.Defined as relapse within 12 months from transplant or progression within the first year of diagnosis, high cytogenetic risk (from FISH) with chromosomal abnormalities (ie, t(4;14), t(14;16), t(14;20), del(17p), 1q gain), R-ISS stage III, high-risk gene expression profiling, and/or high PC S-phase.Defined as a person < 75 years of age, ECOG Performance Status 0-1, no or well-controlled comorbidities, adequate renal and hepatic function, and/or no significant cardiovascular risk factors.Defined as a person ≥ 75 years of age, ECOG Performance Status of 2 or more, wheelchair bound, having comorbidities (including diabetes or congestive heart failure), renal impairment, and/or hepatic impairment.
