Results to be presented at San Antonio Breast Cancer Symposium
AMSTERDAM, Netherlands, Dec. 13 /PRNewswire/ -- Agendia BV, world leader in the rapidly evolving field of molecular diagnostics, announced today that an independent international consortium has demonstrated the prognostic power of its MammaPrint(R) breast cancer prognosis test in patients who have 1-3 positive lymph nodes. The data show that MammaPrint(R) can accurately identify a low risk group of lymph node-positive breast cancer patients with an excellent survival, implications that will help doctors to decide the optimal treatment management.
"Lymph node status is considered to be one of the most powerful prognostic factors for operable breast cancer, with a direct relationship between the number of positive nodes and disease outcome. However, approximately 30% of lymph node-positive patients will remain free of distant metastases without adjuvant chemotherapy," said Dr Laura van 't Veer, chief research officer at Agendia, who participated in the study. "Identifying patients with lymph node-positive disease who are at low risk of recurrence might lead to changes in guidelines for adjuvant chemotherapy."
In the current study, 241 tumor samples from breast cancer patients with 1-3 positive lymph nodes at 2 hospitals were selected and analyzed by the international TRANSBIG consortium. Patients that were classified as "high risk" for recurrence using MammaPrint(R) had significantly worse 5- and 10-year survival rates than those that were identified as "low risk." The numbers indicate that MammaPrint(R) has excellent prognostic power, even in patients having 1-3 positive lymph nodes. The entire study will be presented as an oral presentation at the San Antonio Breast Cancer Symposium on Thursday, December 13 in San Antonio, TX, USA.
"This study is in excellent agreement with our 2002 publication in the
New England Journal of Medicine in which we also found that MammaP
