Recurrence Risk Evaluation by 21-gene Detection

February 12, 2019 updated by: LiNanlin,Ph.D, Chief Physician,Clinical Professor, Xijing Hospital

Postoperative Recurrence Risk Evaluation of Hormone Receptor Positive, Her-2 Negative Breast Cancer by Using Different 21-gene Detection Kits (REBCK)

Breast cancer patients with early breast cancer were enrolled according to the inclusion criteria. Baseline characteristics were recorded from medical record system. Recurrence score were obtained by 21-gene detection kits from different biological companies. Relationship between recurrence score and the prognosis was explored. Meanwhile, the investigators analyzed the consistency of the results obtained from various 21-gene test kits and immunohistochemistry detection.
