Objective To investigate the effect and toxicity of gemcitabine combined with carboplatin treatment on recurrent breast cancer. Methods On the first day and eighth day, gemcitabine（ 1200 mg/m2 ） was diluted with physiologic saline and then used through intravenous drip. on the second day, 350 mg/m2 carboplatin dissolved in 5% glucose solution（500 ml） was used. One cycle lasted for 21 days. Results Among 40 patients, there were 1 complete response（2.5% ）, 16 partial responses（40.0% ）, 15 stable（37.5.0% ） ,8 progressive（20.0% ） .The total effective rate was 42.5 %. Median time to progression was 4.8 months and 1 - year survival rate was 47.5 %. The common toxicities included hanna, vomiting, bone marrow depression and rash.
