To reduce toxicity while maintaining the efficacy of DCF, we reduced the doses of docetaxel （D） and cis-platinum （CDDP）, and administered 5-fluorouracil （5-FU） via a continuous intravenous （CIV） infusion.Methods Chemotherapy-naive patients with gastric adenocarcinomas received D （60 mg/m2 1 hour on day 1）, CDDP （30 mg/m2on days 1 and 2）, and 5-FU （1500 mg·m-2·24 h-1 CIV on days 1 and 8 every 3 weeks）. The primary endpoint was the response rate.Results Fourteen patients were enrolled. Based on the efficacy evaluation following at least 2 cycles of treatment, there was 7.1% complete remission （CR）, 71% partial remission （PR）, 14% stable disease （NC/SD）, and 7.1% progressive disease （PD）. The median survival time was 13 months. Nine patients （64%） had grade Ⅲ-Ⅳ neutropenia, and 4 patients （29%） had grade Ⅳ neutropenia, among whom 1 had grade Ⅳ neutropenia with grade Ⅲ nausea and vomiting.Conclusion The modified DCF regimen is highly active and has a favorable toxicity profile in Chinese patients with gastric cancer.展开更多

So- dium alginate (SA) and N-oleoylsarcosine (NOSARK) were used respectively as linkers between CDDP and magnetic nanometer particles (MNP), and carri- ers-supported CDDP complex of carboxymethyl dex- tran (CM-dex) was used as the control. The physical and chemical characteristics of CDDP-MNP were measured by transmission electron microscope, photon correlation spectrum (PCS), spectrophotome- ter, etc. The advantages and disadvantages of the two linkers were analyzed through comparing the stability and quantity of reversibly bound CDDP. The cis-platinum magnetic nanometer particles were found to have the shape of approximately uniformly pellets under transmission electron microscope. The distribution of PCS diameter was 43―52 nm and the diameter of magnetic nucleus of CDDP- MNP com- plex was about 8.8±1.3 nm. The drug- loading ca- pacity of SA is larger than that of NOSARK, and similar to that of CM-dex. The SA-modified CDDP-MNP solution remained stable after being kept at 4℃ for 40 d. SA is superior to NOSARK as a magnetic nanoparticles surface modifier. Natural SA can supersede CM-dex to serve as linker between CDDP and MNP. In practical application, we should take both the maximal reversible CDDP-bonding capacity and CDDP utilization rate into consideration.展开更多
