Comparison of the DNA index (DI) in primary versus metastatic lesions (Met. 1 to 4) from the same tumors.
| Case | Primary | Met. 1 | Met. 2 | Met. 3 | Met. 4 |
|---|---|---|---|---|---|
| Osteosarcoma 1 * | 2.10 | 1.10/2.14 | 1.12 | ||
| Osteosarcoma 2 * | 0.76 | 0.77/1.56 | 0.79/1.43/1.59 | 0.79/1.55 | 0.78/1.55 |
| Osteosarcoma 3 * | 1.0 | 1.88 | |||
| Osteosarcoma 4 | 1.0 | 1.0 | 1.0 | ||
| Synovial cell sarcoma * | 0.89/1.80 | 1.77 | |||
| Hemangiosarcoma * | 1.89 | 1.0 | 1.0 | ||
| Sarcoma-NOS * | 1.0 | 1.77 | |||
| Fibrosarcoma | 1.0 | 1.0 | 1.0 | ||
| Malignant Peripheral Nerve Sheet Tumor | 1.0 | 1.0 | |||
| Synovial Cell Sarcoma | 0.72 | 0.72 | |||
| Histiocytic Sarcoma | PD | 0.93 | |||
| Liposarcoma | 2.03 | 1.97 |
Note: The variations in the DI became visible as peaks with >10% of the total cell population analyzed. Met: Metastasis, NOS: Not otherwise specified. Marked with an asterisk (*) are six dogs that had significant variation in DI comparing primary-and metastatic lesion.
