Fluoropyrimidine and/or platinum-based chemotherapy is now regarded as a standard first-line treatment in AGC patients because it has shown superiority in terms of response rate and time to disease progression compared with 5-FU monotherapy and other combinations in phase III trials. Despite the lack of evidence for benefit associated with administering salvage chemotherapy, it is a common practice to offer further chemotherapy for AGC patients after first-line failure. For patients who failed after fluoropyrimidine and platinum, taxanes (paclitaxel or docetaxel) and irinotecan have been evaluated extensively in the second-line setting.
