A representative case of GC considered to be endoscopic responder.
An ulcerative lesion (type 3 tumor) showed distinct reduction and flattening after two courses of chemotherapy.

Overall survival (OS, upper) and progression-free survival (PFS, lower) and endoscopy (left) and CT (right) based response evaluations.
Different two groups was assessed using the Kaplan-Meier method and the Log rank test.

Overall survival (OS, upper) and progression-free survival (PFS, lower) in relation to the endoscopy based response evaluation.
Left, patients performing neoadjuvant chemotherapy; right, patients performing chemotherapy alone; Different two groups was assessed using the Kaplan-Meier method and the Log rank test.

Overall survival (OS, upper) and progression-free survival (PFS, lower) and endoscopy (left) and CT (right) based response evaluations in cases who received S1 plus CDDP.
Different two groups was assessed using the Kaplan-Meier method and the Log rank test.

Overall survival (OS, upper) and progression-free survival (PFS, lower) and endoscopy (left) and CT (right) based response evaluations in stage IV cases that have peritoneal dissemination or distant metastasis.
Different two groups was assessed using the Kaplan-Meier method and the Log rank test.
Fig 6.
Overall survival (OS, left) and progression-free survival (PFS, right) among four groups divided according to the endoscopy and CT based response evaluations.
Group 1, responder by both CT and endoscopy; group 2, non-responder by both CT and endoscopy; group 3, non-responder by CT but responder by endoscopy; group 4, responder by CT but no-responder by endoscopy. Different groups was assessed using the Kaplan-Meier method and the Log rank test.
