[The progress of second-line chemotherapy and molecular targeting agents in gastric cancer].
According to the results of Japanese phase III trials recently reported such as JCOG 9912 and SPIRITS, there was a remarkable improvement in median survival time compared to the previous phase III study(JCOG 9205). Many newer agents were used, such as taxane and irinotecan, which were absent during JCOG 9205. Using these agents as a second- line treatment may lead to improved survival. ⋯ On the other hand, molecular targeting agents that have shown activity in other tumor types such as trastuzumab, bevacizumab, cetuximab, and lapatinib are under investigation in global randomized control trials. In these trials, patients from Japan and Korea account for more than half of the enrollees. The number of international studies is increasing, and the role of east Asian countries will be more important in this field.
