Complete Response of Liver Metastasis of Gastric Cancer Treated by S-1 Chemoradiotherapy: A Case Report
Figure 2
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.
