On page 2103 in the 1 March 2012 issue, there are errors for 7 percentages in Table 2. The errors likely arose from using the wrong denominator in the calculations. However, the absolute numbers do not change. Therefore, the data and consequent conclusions do not change. The correct table is shown.
Table 2.
Nonoverlapping classification of primary molecular cytogenetic abnormalities in MM
| FISH abnormality | Frequency (%) (N = 484) |
|---|---|
| Trisomy(ies) without IgH abnormality | 201 (42) |
| IgH abnormality without trisomy(ies) | 146 (30) |
| t(11;14) | 74 (15) |
| t(4;14) | 28 (6) |
| t(14;16) | 19 (4) |
| t(14;20) | 1 (<1) |
| Unknown partner/deletion of IgH region | 24 (5) |
| IgH abnormality with trisomy(ies) | 74 (15) |
| t(11;14) | 12 (3) |
| t(4;14) | 19 (4) |
| t(14;16) | 5 (1) |
| t(6;14) | 3 (<1) |
| Unknown partner/deletion of IgH region | 35 (7) |
| Monosomy 14 in absence of IgH translocations or trisomy(ies) | 22 (4.5) |
| Other cytogenetic abnormalities in absence of IgH translocations or trisomy(ies) or monosomy 14* | 26 (5.5) |
| Normal | 15 (3) |
*
These included primarily monosomy 13 and p53 abnormalities.
