Arm Intervention/treatment
Active Comparator: Mycet/Cyclophosphamid
4 x Myocet 60 mg/m² q3w in combination with 4 x cyclophosphamide 600 mg/m² q3w depending on early response assessment by ultrasound or on toxicity profile.
Drug: Myocet
Other Name: Doxorubicin

Drug: Cyclophosphamide
Active Comparator: Myocet/Cyclophosphamide/Paclitaxel
2 x Myocet 60 mg/m² q3w in combination with 2 x cyclophosphamide 600 mg/m² q3w followed by 6 x paclitaxel 80 mg/m² q1w depending on early response assessment by ultrasound or on toxicity profile.
Drug: Myocet
Other Name: Doxorubicin

Drug: Cyclophosphamide

Primary Outcome Measures :
  1. Comparison of pCR rates in patients with early response and no severe toxicity (Group 1) and in other patients (Group 2). [ Time Frame: After 5 years of follow-up. ]

Secondary Outcome Measures :
  1. Incidence of febrile neutropenia (FN) after 1 x MC in patients with primary prophylaxis (PP) vs. others. [ Time Frame: After 5 years of follow-up. ]
  2. Toxicity in the 4 x MC versus 2 x MC followed 6 x Pac arm as measured by adverse events. [ Time Frame: After 5 years of follow-up. ]
  3. Number of pCR in non-responders to MC. [ Time Frame: After 5 years of follow-up. ]
  4. G-CSF use in terms of primary or secondary prophylaxis per patient including occurence febrile neutropenia per patient per cycle [ Time Frame: After 5 years of follow-up. ]
