Table 1.
The Number of Ki67-Positive Cells, the Number of Vessels (Factor VIII-Positive), and the Percentage L-19-Positive Vessels Were Calculated in Five Different Areas of Each Specimen at ×250 Microscopy Magnification
| No. of cases | % of B-FN-positive vessels per HMF* | No. of vessels per HMF* | No. of Ki67-positive cells per HMF* | Survival of patients at 24 months | |
|---|---|---|---|---|---|
| Low grade | 29 | 1.6 ± 2.6 | 17.7 ± 11.7 | 1.0 ± 1.9 | 90% |
| High grade | 28 | 92.0 ± 8.7 | 40.7 ± 28.4 | 34.2 ± 26.8 | 12% |
| Discriminating analysis: % of cases correctly classified | 100 | 64 | 89 |
The average and standard deviation were calculated for each parameter. Discriminating analysis was applied to evaluate the percentage of cases correctly classified for each of the three parameters tested.
