Background: TNBC shows a very bad prognosis: median time to relapse is 18 months and median overall survival (OS) is less than 24 months. Methods: AMBRA is a longitudinal cohort study, describing the choice of 1st- and subsequent treatments in HER2-ve MBC pts in the years 2012-2015. The present analysis is focused on TNBC pts (127 out of 879 evaluable; 14.4%) and CHT strategies, overall and according to adj treatment. Kaplan Meyer probability of survival from primary (DFS), 1st (PFS1) and 2nd (PFS2) progression and Time from last CHT and death were calculated for the whole population and according the main adj regimens. Results: Median age at primary diagnosis was 53 years. The most used regimens in the adj setting were anthra/taxane(tax) 50.7%, anthra 22.1% or others (CMF included) 20.6%). Median time to events was: DFS 23.2, PFS16.5 and PFS2 4.3 months, respectively. CHT choices in the metastatic setting according to adj treatment were: Conclusions: Our results show that taxanes play a crucial role in MBC even if used in 50% of Adj. CAPE/VRL, Platinum regimens and Eribuline are also widely used. Time from last CHT administration and Death is very short in 30% of cases
