RESUMO
Background and purpose:At present,the treatment of metastatic breast cancer has remained diff icult for patients who have failed after the use of anthracycline and taxane,so the treatment options for those with advanced metastatic breast cancer are very limited.Therefore,pemetrexed combined with cisplatin in the treatment of anthracycline and taxane failed advanced metastatic breast cancer patients,its effi cacy and adverse reactions were studied.Methods:10 patients with advanced metastatic breast cancer patients received pemetrexed and cisplatin chemotherapy,pemetrexed 500mg/m2 intravenous infusion,cisplatin 75mg/m2 intravenous drip,repeated every 3 weeks.Evaluation of response and adverse reactions were practiced every 2 cycles.Results:10 patients were evaluable,CR 1 patient,PR 4 patients,SD 2 patients,PD 3 patients.With a median follow-up of 6 months(4-18 months),8 patients survived and 2 patients died.The median time to progression was 4 months(3-14 months),the median survival time was 8 months(4-18 months).The most common adverse reaction was fatigue,white blood cells decrease and the digestive tract reactions,followed by oral ulcers.Conclusion:Pemetrexed combined with cisplatin in the treatment of anthracycline and taxane treatment failed patients with advanced metastatic breast cancer could improve survival,adverse reactions could be tolerated.
