Prosigna
Breast Cancer Recurrence Risk
Why undergoing this examination?
In recent years, the understanding of breast cancer has evolved significantly, now considered a complex and heterogeneous pathology. Therefore, distinct factors must be considered to determine the patient’s prognosis. Women with early-stage breast cancer expressing estrogen receptors usually have a good prognosis. However, in this population, about 50% of recurrences occur after five years of diagnosis. An imminent need in the management of estrogen receptor-positive breast cancer is to identify women at increased risk for late recurrence.
What is this exam?
Prosigna (PAM50) was developed based on a PAM50 genetic signature that provides the patient’s risk of recurrence information (ROR – Risk Of Recurrence) based on three factors: tumor size, intrinsic molecular subtype, and tumor proliferation status.
For whom is it indicated?
Postmenopausal women who have undergone mastectomy due to breast cancer and have the following characteristics:
- Hormone receptor-positive, node-negative, stage I and II breast cancer;
- Hormone receptor-positive, node-positive (1-3, 4 or more positive nodes), stage II or IIIA breast cancer.
