The patient who died 1275 days after diagnosis had poorly differentiated adenocarcinoma invading SMV via the right gastroepiploic vein and the tumor in SMV almost totally regressed after chemotherapy; this was the only patient who was responsive to chemotherapy (Figure 5).
In the present study, two patients had SMV invasion via the right gastroepiploic vein. One of these two patients underwent distal gastrectomy because there was no evidence of any metastases and pathological examination also revealed lack of lymph node metastasis.
Coronal (a) and axial (b) CT images demonstrating tumoral infiltration through the course of the right gastroepiploic vein (asterisks, a, b).
