Cancer Prognosis
FEMTELLE® is intended for the quantitative measurement of human Urokinase-type Plasminogen Activator (uPA) and human Plasminogen Activator Inhibitor Type-1 (PAI-1) in detergent extracts of breast tumor tissue. uPA and PAI-1 are clinically validated independent prognostic markers in breast cancer and have reached the highest Level of Evidence (LoE-1) according to the “Tumor Marker Utility System”.

CE Marked
Prospective, randomized multi-center clinical trials as well as retrospective meta-analyzes have shown that measurement of both uPA and PAI-1 levels in extracts of breast cancer tumor tissue can help to assess the risk of disease recurrence. FEMTELLE results are useful for the following indications:
1. Prognosis for breast cancer patients who are either at low or high risk for disease recurrence following surgery. A low level of both uPA and PAI-1, below the established cutoff value of 3 ng uPA/mg of total protein and 14 ng of PAI- 1/ mg total protein, places the patient in the low risk category for disease recurrence. A high level of uPA and/or PAI-1, above the respective cut-off values, correlate with a significantly shortened Disease Free Survival (DFS) and reduced Overall Survival (OS) as compared to patients with tumor tissue containing low levels.
2. Prediction: It has been proposed that uPA and PAI-1 levels may be used to predict patient response to adjuvant chemotherapy. Clinical trials suggest that breast cancer patients with low uPA and PAI-1 are unlikely to benefit from adjuvant chemotherapy, whereas those patients with high uPA and PAI-1 levels are more likely to benefit from adjuvant chemotherapy.
Results from FEMTELLE should be used in conjunction with information available from clinical and other diagnostic procedures in the management of breast cancer disease
