title: A randomised trial of goserelin versus control after adjuvant, risk-adapted chemotherapy in premenopausal patients with primary breast cancer - GABG-IV B-93.
abstract: GABG-IV B-93 is a prospective, randomised study comparing goserelin (n=384) with no further treatment (n=392) in hormone receptor (HR)-negative breast cancer patients (n=465) after 3 cycles cyclophosphamide, methotrexate, 5-fluorouracil (CMF) for patients with 0-3 positive lymph nodes (LN) or 4 cycles epirubicin, cyclophosphamide (EC) followed by 3 cycles CMF for patients with 4-9 positive LN. After completion of the ZEBRA trial the study was amended to enrol also HR-positive patients with 1-9+LN (n=311). After a median follow-up of 4.7 years neither HR-negative nor HR-positive patients showed a benefit for goserelin. The adjusted estimated hazard ratio for event-free survival in HR-negative patients was 1.01 (goserelin versus control, 95% confidence interval [CI] 0.72-1.42, P=0.97) and 0.77 in HR-positive patients (95% CI 0.47-1.24, P=0.27). These results do not support the general use of goserelin after adjuvant chemotherapy in this group of premenopausal patients.
