Continuous Intravenous Infusion Paclitaxel Based Combination Regimen as Second Line Chemotherapy for Advanced Esophageal Squamous Cell Carcinoma

Purpose] To investigate the response and toxicity of continuous intravenous infusion paclitaxel based combination regimen as second line chemotherapy for advanced esophageal squamous cell carcinoma（ESCC）.Methods] Twenty-six with ESCC pathologically proved received continuous intravenous infusion paclitaxel（PTX） based combination regimen.The regimen schedule was：PTX 20mg/m2,civ,16h,d1-3,d8-9;DDP 3.75mg/m2,iv,d1-4,d8-11,5-Fu 375mg/m2,civ,24h,d1-5,d8-12;folic acid 60mg,po,d1-5,d8-12.Twenty-one days as a cycle,and each patient was treated at least two cycles.Results] Response was evaluable in 23 cases with≥2 cycles,1 case in CR,9 cases in PR,10 cases in SD and 3 cases in PD,the overall response rate was 43.5%.The median TTP was 5.1 months.The main toxicities were myelosuppression and alopecia,and other toxicities were mild.Conclusion] Continuous intravenous infusion paclitaxel based combination regimen for advanced ESCC is effective and tolerable.
