Similar results were observed for clinical response ( objective response was 54 % vs 56 % , p = .18 ) , breast conservation surgery ( BCS ; 67 % vs 68 % , p = .97 ) , and pathological complete response rate ( Chevallier classification : 14 % vs 11 % , p = .68 ; Statloff classification : 16 % vs 13 % , p = .82 ) between arms A and B. Similar toxicities were observed , even with unbalanced numbers of FEC100 and docetaxel courses .
