Popis: We aimed to examine the effects of palbociclib and neutropenia in patients with metastatic breast cancer(MBC). From December 2017 to December 2019, 18 patients with estrogen receptor(ER)-positive, human epidermal growth factor receptor 2(HER2)-negative MBC were treated with palbociclib for at least 1 cycle. The most common adverse event(AE) was neutropenia, which occurred in 83% of all cases. With cessation and dose reduction, none of the patients had Grade 4 neutropenia. Palbociclib used in the first- or second-line treatment of MBC showed a higher efficacy than when used as the third-line treatment, which was observed as a longer duration to stay on treatment and higher efficacy.
