title: [Results of 10 years of a randomized trial of neoadjuvant chemotherapy in breast cancers larger than 3 cm].
abstract: OBJECTIVE
  The aim of this randomised trial was to determine advantages and drawbacks of neo-adjuvant chemotherapy in patients with operable breast cancers > 3 cm.
  
  
  METHODS
  Two hundred and seventy-two women (age 70) with operable breast cancers larger than 3 cm (T2-3/N0-1/M0) were included in a randomised trial from January 1, 1985 to April 30, 1989. Patients in group A (n = 138) were treated by mastectomy and axillary node dissection. Adjuvant chemotherapy was indicated for 104 patients with axillary node involvement (n = 82) or negative oestrogen and progesterone receptors (EPR-) (n = 22). Patients in group B (n = 134) were treated by initial chemotherapy (identical as in group A) followed by locoregional treatment according to the response. Before treatment, the average of clinical tumoural diameter was 43 mm.
  
  
  RESULTS
  The median follow-up was 124 months. In group B, 49 patients (36.5%) were resistant to chemotherapy; a conservative breast surgical treatment was performed in the other 84 patients sensitive to chemotherapy (62.6%). In this last subgroup, 19 (22.6%) needed a secondary mastectomy because of locoregional recurrence. Survival rates were not different in groups A and B, but loco-regional recurrences were frequent in group B. At 10 years, the overall survival rate was 60% and half of living patients in group B were free of cancer and with their breast.
  
  
  CONCLUSIONS
  Neoadjuvant chemotherapy permitted in two-thirds of cases breast conservation treatment, initially considered to be impossible. Locoregional recurrences are more frequent than after mastectomy and adjuvant chemotherapy.
