Clinical effects of vinorelbine combined with cisplatin in the treatment of patients with advanced breast cancer

Abstract

Objective To investigate the efficacy and security of vinorelbine combined with cisplatin in the treatment of advanced breast cancer patients resistant to antracyclines and/or taxanes.Methods Seventy-three patients with advanced breast cancer resistant to anthracyclines and/or taxanes received NP regimen:Vinorelbine(NVB 25 mg/m2,intravenous infusion, day 1,8) plus cisplatin(DDP 75-85 mg/m2,intravenous infusion in 2-5 days).Three weeks as one period of treatment.The evaluation was performed two weeks after every two periods of treatment. Results Seventy-one patients were evaluated for efficacy and toxicity of the therapy, the overall response was 63.4%(45/71),3 cases (4.2%) had complete response,42 cases(59.2%)had partial response,while 23 cases(32.4%) had stable disease and progressive disease were 3 cases(4.2%).The efficacy in patients who had received radiotherapy were more effective than those without radiotherapy(P=0.029).The efficacy in patients with single metastatic organ were more effective than those with multiple organs(P=0.005). The common toxicities were myelosuppression and gastrointestinal reactions.Conclusions Vinorelbine combined with cisplatin are tolerable and effective in the treatment of advanced breast cancer with anthracycine and/or taxanes resistance.
