Outcomes of Palliative Weekly Low-Dose Gemcitabine-Cisplatin Chemotherapy in Anthracycline- and Taxane- Pretreated Metastatic Breast Cancer Patients / 한국유방암학회지
We collected clinicopathological data from MBC patientswho had been treated with gemcitabine, 800 mg/m2 plus cisplatin, 30 mg/m2 intravenously, on days 1 and 8 every 3 weeks, between January 2001 and November 2011 in Korea.
RESULTS:
The analysis included 294 patients previously treated anthracycline-xand taxane-based chemotherapies prior to GP (median age, 48 years [range, 28-78 years]; median follow-up duration, 63.9 months). Seventeen patients (5.8%) discontinued GP because of toxicities. The median progression-free survival (PFS) was 3.9 months (95% confidence interval [CI], 3.394.4 months) and the median overall survival (OS) was 27.7 months (95% CI, 17.6-37.8 months) months. Statistically significant factors for PFS were performance status (Eastern Cooperative Oncology Group, > or =2 vs. 2 years; HR, 1.66; 95% CI, 1.28-1.95, p1 year; HR, 1.48; 95% CI, 1.13-1.95, p2 years; HR, 2.07; 95% CI, 1.36-3.14; p<0.001) and the presence of brainmetastasis (HR, 2.14; 95% CI, 1.27-3.61; p=0.004) were important factors for OS after GP treatment.
