Experimental: neoadjuvant chemo-endocrine therapy
In the experimental arm, patients received concurrent chemotherapy (fluorouracil 500mg/m2 IV, epirubicin 90mg/m2 IV and cyclophosphamide 500mg/m2 IV on day 1 at 3-weekly intervals for 3 cycles followed by docetaxel 100mg/m2 IV on day 1 at 3-weekly intervals for 3 cycles; or epirubicin 90mg/m2 IV and cyclophosphamide 600mg/m2 IV on day 1 at 2-weekly intervals for 4 cycles, followed by docetaxel 100mg/m2 IV on day 1 at 2-weekly intervals for 4 cycles) with endocrine therapy (letrozole with or without leuprorelin) as a neoadjuvant treatment
|
Postmenopausal patients were treated with letrozole 2.5mg/day p.o until complement of neoadjuvant chemotherapy before surgery, while premenopausal ones received letrozole 2.5mg/day p.o and a subcutaneous injection of the GnRH-a, leuprorelin, as concomitant treatment with neoadjuvant chemotherapy (fluorouracil 600mg/m2 IV, epirubicin 90mg/m2 IV and cyclophosphamide 600mg/m2 IV on day 1 at 3-weekly intervals for 3 cycles followed by docetaxel 100mg/m2 IV on day 1 at 3-weekly intervals for 3 cycles; or epirubicin 90mg/m2 IV and cyclophosphamide 600mg/m2 IV on day 1 at 2-weekly intervals for 4 cycles, followed by docetaxel 80mg/m2 IV on day 1 at 2-weekly intervals for 4 cycles), letrozole was delivered after 1 week of first dose of leuprorelin injection.

Active Comparator: neoadjuvant chemotherapy alone
In the control group, patients received neoadjuvant chemotherapy alone (fluorouracil 500mg/m2 IV, epirubicin 90mg/m2 IV and cyclophosphamide 500mg/m2 IV on day 1 at 3-weekly intervals for 3 cycles followed by docetaxel 100mg/m2 IV on day 1 at 3-weekly intervals for 3 cycles; or epirubicin 90mg/m2 IV and cyclophosphamide 600mg/m2 IV on day 1 at 2-weekly intervals for 4 cycles, followed by docetaxel 100mg/m2 IV on day 1 at 2-weekly intervals for 4 cycles)
|
Patients received fluorouracil 500mg/m2 IV, epirubicin 90mg/m2 IV and cyclophosphamide 500mg/m2 IV on day 1 at 3-weekly intervals for 3 cycles followed by docetaxel 100mg/m2 IV on day 1 at 3-weekly intervals for 3 cycles; or epirubicin 90mg/m2 IV and cyclophosphamide 600mg/m2 IV on day 1 at 2-weekly intervals for 4 cycles, followed by docetaxel 100mg/m2 IV on day 1 at 2-weekly intervals for 4 cycles.
