Ability of sentinel lymph node to predict malignancy
| Final pathology of all lymph nodes | ||
| Malignancy present | No malignancy present | |
| Sentinel lymph node positive for malignancy (mapped) | 19 | 0 |
| Sentinel lymph node negative for malignancy (mapped) | 2* | 153 |
Sensitivity = 90.5%.
Specificity = 100%.
Positive predictive value = 100%.
Negative predictive value = 98.7%.
*one patient had a sentinel lymph node that was adipose-only, the other patient had an ITC pelvic node.
