Breast cancer is the most common tumor in women and one of the leading causes of cancer death in women. Breast cancer 21 gene detection is a quantitative detection of the mRNA expression of 21 breast cancer-related genes. The gene expression is converted into a recurrence score ( RS ) by a specific algorithm. The results can provide information for prognosis, recurrence, and treatment guidance.
The NCCN guideline recommends 21 gene detection for adjuvant chemotherapy evaluation in patients with HR + / HER2- / N0 ~ 1 breast cancer, and ASCO and CSCO breast cancer guidelines are also strongly recommended.
HR + / HER2-/ NO ~ 1 breast cancer patients
Patients with HR+ and HER2- invasive breast cancer can evaluate the risk of recurrence and the benefit of chemotherapy through 21 gene detection, which is helpful for a clinical selection of appropriate treatment options.
Preferred Recommendation
NCCN guidelines preferred gene expression assay, which can predict the efficacy of chemotherapy and evaluate prognosis
Rigorous Data
Through a large number of clinical studies ( retrospective, prospective ) and clinical practice, the test results are more reliable
Interpretation Science
RS values were divided into three groups of high, medium and low risk, and stratified statistics of lymph node status and menopausal status factors were included to evaluate the prognosis of patients and guide adjuvant therapy in more detail
Fast Detection
The use of eight pipe pre-packing form, reduce the operation steps, improve the detection efficiency
Stable and Reliable
The use of capping agent anti-pollution system, effectively avoid cross-contamination, improve detection specificity
