Cytometric prognostic parameters in breast cancer.

Prognostic parameters were examined in a retrospective survey of 730 cases of overt distant metastasis-free invasive breast cancer. A multivariate combination of cytometric and clinical parameters allowed the stratification of patients into five prognostic categories. In the low-risk group the distant recurrence rate was only 3.3%, In the highest risk group 57%. We conclude that cytometric parameters can increase the precision of prognostic evaluation in invasive breast cancers, and thus aid in decisions.
