Fig. 2From: Combination of t(4;14), del(17p13), del(1p32) and 1q21 gain FISH probes identifies clonal heterogeneity and enhances the detection of adverse cytogenetic profiles in 233 newly diagnosed multiple myelomaDistribution of abnormalities according to the number of clones at diagnosis (n = 184). 1q21 gain was more frequent in the subgroup of 2 clones or more (81.6%) compared to the subgroup of 1 clone (18.4%) (p < 0.0001), del(1p32) was more frequent in the subgroup of 3 clones or more (28.0%) compared to the subgroup of 1 or 2 clones (5.8%) (p = 0.002). No preferential distribution was observed with del(17p13) and t(4;14) translocationBack to article page
