PersonaLized neoAdjuvant Strategy ER Positive and HER2 Negative Breast Cancer TO Increase BCS Rate
NCT03900637 · Status: ACTIVE_NOT_RECRUITING · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 122
Last updated 2024-07-31
Summary
In ER+ and HER2- breast cancer(BC) patients for whom BCS is not feasible, we investigate the rate of BCS can be increased while decreasing unnecessary chemotherapy thru selective neoadjuvant chemotherapy or neoadjuvant endocrine therapy using tools of nodal status, Ki-67, and multigene assay(Mammaprint)
Conditions
Interventions
- DRUG
-
Leuprorelin acetate
In premenopausal women, 3.75mg of leuprorelin acetate is subcutaneously administered once every 4 weeks for 16 weeks. (if needed, maximum for 24 weeks)
- DRUG
-
2.5 mg tablet is orally administered once a day, without regard to meals, for 16 weeks (if needed, maximum for 24 weeks)
- GENETIC
-
MammaPrint
In this study, patients with MammaPrint test is performed, neoadjuvant chemotherapy is conducted to genomic High Risk patients, and neoadjuvant endocrine therapy is conducted to Low Risk patients.
