Completed

Conditions

Detailed Description

There is no evidence of treatment after progression of Ful. We retrospectively evaluated HR+, HER2- MBC patients failed on Ful 500mg as first line or second line therapy from 2014 to 2017 in 6 institutions. Treatment pattern, PFS, OS and safety were analyzed to figure out the situation and efficacy of treatment after Fulvestrant.
