case_images: Resected specimen and pathological findings. (a) Macroscopic appearance of surgically resected specimen showing type 2 advanced gastric cancer in the corpus of the stomach. (b) Pathological examination showing a poorly differentiated adenocarcinoma (H&E stain).

case_images: Pathological examination showed a poorly differentiated adenocarcinoma invading the muscularis propria, without lymph node metastasis (T2a N0 M0/Stage 1B, Figures 1(a) and 1(b)).
case_images: Abdominal computed tomography (CT) findings. (a)-(b) CT scan before chemoradiotherapy showing multiple liver metastases in S5 and S6. (c)-(d) CT scan after 5 cycles of S-1 administration showing disappearance of the tumor in S5, while tumor was still visible in S6. (e) CT scan after radiation and 10 cycles of S-1 administration showing reduction of tumor in S6. (f) CT scan after radiation and 15 cycles of S-1 administration showing disappearance of liver metastasis; hence, this case was interpreted as a complete response.

case_images: In 2009, an abdominal computed tomography (CT) scan showed multiple heterogeneous low-density masses in S5 and S6 of the liver (Figures 2(a)-2(b)). Abdominal CT after 5 cycles of S-1 revealed a virtual complete disappearance of the tumors in S5 but not of those in S6 (Figure 2(c)-2(d)). Abdominal CT after radiation and 10 cycles of S-1 showed reduction in the tumor masses in S6 (Figure 2(e)). Another series of abdominal CT performed after radiation and 15 cycles of S-1 showed complete disappearance of liver metastasis (Figure 2(f)).
