For your patients with HR+, HER2-, early-stage, invasive breast cancer
The Oncotype DX Breast Recurrence Score® report provides three points of clarity to aid in treatment decisions as to whether adjuvant chemotherapy is needed or not for node-negative and node-positive (N1: up to 3 positive lymph nodes), hormone receptor-positive, HER2-negative, early-stage breast cancer patients.

3 pieces of information provided by the test
Recurrence Score® result
This number, between 0 and 100, is calculated by measuring the activity of specific genes in the breast cancer tissue. The Recurrence Score result is used to predict the risk of the breast cancer returning at a distant site and whether chemotherapy may help reduce the risk.1-5
- These results are valid in HR+, HER2-, early-stage, invasive breast cancer patients treated with 5 years of endocrine therapy.

Node-Negative
 |
Recurrence Score result |
|
The Recurrence Score result is based on the quantitative analysis of the expression of 21 genes within the patient’s tumour sample. This number, from 0 to 100, is used to determine distant recurrence risk at 9 years (prognosis) and absolute chemotherapy benefit (prediction). |

Prognosis |

Your patient’s individualised 9-year distant recurrence risk (%) with endocrine therapy alone.* *Based on the |

Prediction |

The absolute chemotherapy benefit (%) is based on the average benefit of chemotherapy in patients who had the same range of Recurrence Score results.* *Based on the |

| Quantitative ER, PR, and HER2 scores by RT-PCR, specific to your patient. |
 |
Estimated Chemotherapy Benefit |
|
The NSABP B-20 study randomized patients to treatment with TAM alone or TAM + CT and validated that Recurrence Score results are predictive of chemotherapy benefit.
|
 |
Benefit Increase |
|
The TAILORx study is a prospective trial in which patients with Recurrence Score results between 11-25 were randomly assigned ET alone or ET + CT. Treatment with ET alone was found to be non-inferior to ET + CT across patients of all ages. An exploratory subgroup analysis in patients ≤50 years of age showed a small chemotherapy benefit beginning at Recurrence Score results of 16, and the benefit increases as the Recurrence Score result increases.

Further understanding the results
Node-negative patients
Patients with a Recurrence Score result of 0-25 generally do not benefit from the addition of chemotherapy to endocrine therapy.2,3,6
For patients under 50 years of age there is some chemotherapy benefit (in terms of DRFI) for those with Recurrence Score result 16 and above.6
Patients with Recurrence Score results 26–100 significantly benefit from the addition of chemotherapy to endocrine therapy.2,3
For patients under 50 years of age there is some chemotherapy benefit (in terms of DRFI) for those with Recurrence Score result 16 and above.6
Patients with Recurrence Score results 26–100 significantly benefit from the addition of chemotherapy to endocrine therapy.2,3
Node-positive patients
Post-menopausal patients with a Recurrence Score result of 0–25 do not benefit from the addition of chemotherapy to endocrine therapy.4,7
Pre-menopausal patients with Recurrence Score results of 0-25 have a 2.4% benefit (in terms of DRFI) from the addition of chemotherapy to endocrine therapy.8
All patients with Recurrence Score results 26-100 significantly benefit from the addition of chemotherapy to endocrine therapy.4
Pre-menopausal patients with Recurrence Score results of 0-25 have a 2.4% benefit (in terms of DRFI) from the addition of chemotherapy to endocrine therapy.8
All patients with Recurrence Score results 26-100 significantly benefit from the addition of chemotherapy to endocrine therapy.4
