title: Chemotherapy for metastatic gastric cancer in Japan.
abstract: Until the 1990s, there were no chemotherapy regimens with old-generation anticancer agents showing a survival benefit over 5-fluorouracil (FU) alone, and standard chemotherapy for metastatic gastric cancer had not been established. In the late 1990s, several new active agents were developed and some phase III trials with these agents were conducted; the new agent S-1 showed noninferiority to 5-FU in these trials. S-1 plus cisplatin is the first doublet chemotherapy to have shown a survival benefit over monotherapy with S-1. It has been demonstrated that capecitabine and oxaliplatin (OHP) can replace 5-FU and cisplatin (CDDP), offering more convenient treatment options. Thus, combination chemotherapy with an oral fluoropyrimidine (S-1 or capecitabine) and platinum (CDDP or OHP) has been recognized as standard chemotherapy for metastatic gastric cancer all over the world. However, it can be said that none of these new combination chemotherapies have shown remarkable progress from 5-FU plus cisplatin regimens. It is expected that triplet chemotherapy with a taxane; the use of molecular targeting agents; and the establishment of treatment strategies including second line chemotherapy, will lead to remarkable progress in personalized medicine in the near future.
