Cytogenetic/molecular risk categories and clinical outcomes
| Cytogenetic risk category | Karyotype | Complete remission | Overall survival | References |
|---|---|---|---|---|
| Favorable | t(15;17), t(8;21), inv(16) | 75-88% | 3-yr 38% | [8,19,32,117,118] |
| -OR- | 5-yr 17-38% | |||
| Normal karyotype with NPM1 mut/FLT3 wt | 68-83% | 3-yr 29-33% | [26,28,32] | |
| 5-yr OS 21% | ||||
| Intermediate | Normal karyotype not associated with favorable molecular markers; cytogenetic abnormalities not included in other groups | 51-63% | 3-yr 18% | [8,19] |
| 5-yr 11-16% | ||||
| Adverse | Complex (3 or more, not including a favorable abnormality), monosomy (especially complete or partial deletion of 5 or 7), inv(3), t(9;22), 11q23 or 17p abnormalities | 26-40% | 3-yr < 5% | [15,18,19,32,117] |
