Table 2.
Detection of monosomy 15 in tumor and nontumor cells
| Variable | Monosomy 15 in Tumor (PCs) and Nontumor Cells, n = 39 | Monosomy 15 in Tumor Cells (PCs) Only, n = 3 |
|---|---|---|
| Average % of monosomy 15 in tumor cells | 98% (45%-100%) | 78% (41%-100%) |
| Average % of monosomy 15 in nontumor cells | 100% | 0% |
Seven cases had an unknown status of multiple myeloma tumor vs nontumor cells. Nontumor cells: 100% of the cells had monosomy 15.
