Biomarker Test May Spare Breast Cancer Patients
Researchers presented data from a prospective, multicenter trial in Germany at the recent American Association for Cancer Research meeting in San Francisco. About 240 women whose primary tumors had low concentrations of urokinase-type plasminogen activator and its inhibitor, called "PAI-1," received no treatment after surgery.
The researchers determined that, after a median follow-up of 32 months, the women had less than a 10 percent risk of relapse. On the basis of these results, the researchers recommend routine monitoring of the two biomarkers.
