Choose the test with proven prognostic performance

The Prosigna assay, designed from the foundations of breast cancer biology, provides the confidence to help make the right choices.

The need for greater prognostic performance

Knowing and being confident in the measurement of recurrence risk is an important consideration for deciding which treatment to recommend in ER+/HER2- breast cancer.1

The Prosigna Breast Cancer Assay is intended for post-menopausal women with early-stage HR+ and HER2- breast cancer.

The Prosigna prognostic gene signature assay is a 2nd generation test that has shown improved performance when compared with older genomic assays.

The Prosigna risk of recurrence (ROR) score adds significant prognostic information to conventional risk factors such as pathological analysis of the patient tumor, and protein markers detected using immunohistochemistry.2

More comprehensive information on the risk of recurrence

The Prosigna® Breast Cancer Prognostic Gene Signature Assay reports three key pieces of information specific to your patient:

  1. Risk Group (Low, Intermediate, High)
  2. Risk of Recurrence (ROR) Score
  3. Intrinsic Subtype (Luminal A, Luminal B, HER2-enriched, Basal-like)

Prosigna ROR score provides more accurate prognostic information on the risk of distant recurrence among gene-expression and immunohistochemical biomarkers.2

The Prosigna assay accurately classifies patients into low, intermediate, or high risk of distant recurrence.

In a real-world setting, the Prosigna assay reliably identified low-risk patients that were either node-negative or had one to three positive nodes, which could help clinicians decide if a patients could safely avoid adjuvant chemotherapy.3 The Danish Breast Cancer Cooperative Group (DBCG) examined distant recurrences in a comprehensive nationwide cohort consisting of 2,558 postmenopausal women with hormone receptor-positive early breast cancer treated with 5 years of endocrine therapy alone.3

The Prosigna ROR score more accurately estimated the probability of 10-year distant recurrence in this population compared with the risk stratification provided by other gene panels.3.4

An accurate prognosis is the foundation of long-term treatment recommendations

Extensive global evidence of clinical validity and clinical utility in over 5,200 patients treated with 5 years of standard-of-care hormone therapy and 10 year follow-up (prospective and populational)

Low and high risk differentiation is a key factor for determining a confident treatment decision

The recurrence risk results of more than a half (59%) patients in sub-analysis of 663 of the original 774 samples within the TransATAC study were discordant between Prosigna and Oncotype Dx. The observed outcomes were more consistent with the Prosigna risk category, not the Oncotype DX risk category.6

The Prosigna assay provides accurate prognostic information

Identify patients that can safely avoid over-treatment

Uniquely designed to inform treatment decisions

In addition to the intrinsic subtype, the Prosigna assay combines tumor size, nodal status and proliferation score to determine the 10-year risk of recurrence (ROR) score7

  • Determine Intrinsic (Molecular) Subtype Through Pearson’s Correlation to Centroids
  • Calculate Prosigna Score
  • Estimate 10-Year Risk of Distant Recurrence on Endocrine Therapy Alone

Identifying the PAM50 molecular subtype of a tumor

The Prosigna gene expression assay is the only breast cancer prognostic test developed from the four PAM50 molecular subtypes.9
The classification into the intrinsic subtypes, enables a more accurate assessment of tumor gene expression patterns.10

There is considerable discordance between IHC-based subtype and the Prosigna molecular subtypes.10

Patient outcomes based on molecular subtypes has been assessed in a head-to-head comparison with IHC and the Prosigna assay was shown to be more accurate.6 Errors in assigning subtype can significantly affect breast cancer treatment and outcomes (St. Gallen International expert concensus11).
