摘要
Metastatic gastric cancer remains an incurable disease,with a relative 5-year survival rate of 7%-27%.Chemotherapy,which improves overall survival(OS) and quality of life,is the main treatment option.Metaanalysis has demonstrated that the best survival results obtained in earlier randomized studies were achieved with three-drug regimens containing a fluoropyrimidine,an anthracycline,and cisplatin(ECF).Although there has been little progress in improving median OS times beyond the 9-mo plateau achievable with the standard regimens,the availability of newer agents has provided some measure of optimism.A number of new combinations incorporating docetaxel,oxaliplatin,capecitabine,and S-1 have been explored in randomized trials.Some combinations,such as epirubicin-oxaliplatin-capecitabine,have been shown to be as effective as(or perhaps more effective than) ECF,and promising early data have been derived for S-1 in combination with cisplatin.One factor that might contribute to extending median OS is the advancement whenever possible to second-line cytotoxic treatments.However,the biggest hope for signif icant survival advances in the near future would be the combination of new targeted biological agents with existing chemotherapy f irst-line regimens.
Metastatic gastric cancer remains an incurable disease, with a relative 5-year survival rate of 7%-27%. Chemotherapy, which improves overall survival （OS） and quality of life, is the main treatment option. Metaanalysis has demonstrated that the best survival results obtained in earlier randomized studies were achieved with three-drug regimens containing a fluoropyrimidine, an anthracycline, and cisplatin （ECF）. Although there has been little progress in improving median OS times beyond the 9-mo plateau achievable with the standard regimens, the availability of newer agents has provided some measure of optimism. A number of new combinations incorporating docetaxel, oxaliplatin, capecitabine, and S-1 have been explored in randomized trials. Some combinations, such as epirubicin-oxaliplatincapecitabine, have been shown to be as effective as （or perhaps more effective than） ECF, and promising early data have been derived for S-1 in combination with cisplatin. One factor that might contribute to extending median OS is the advancement whenever possible to second-line cytotoxic treatments. However, the biggest hope for significant survival advances in the near future would be the combination of new targeted biological agents with existing chemotherapy first-line regimens.
