Review: (Neo)adj. Taxan  Anthrazyklin vs.
Anthrazyklin  Taxan beim EBC
• Seven studies in the adjuvant setting and eight in the neoadjuvant setting
(10 randomized trials)
• Nearly 5000 patients
• None of the clinical trials has shown disadvantages in terms of efficacy or
toxicity for…taxane…first.
• Similar or increased pathological complete response rates for sequences
in which the taxane…first.
Conclusion: There seems to be sufficient evidence to
suggest that a taxane followed by an anthracycline is a
sequence option that can be incorporated into daily
clinical practice.
