[Noticeable clinical response to S-1/CDDP combination therapy for Virchow node recurrence after surgery for advanced gastric carcinoma with marked involvement of the esophagus - report of a case].

We have recently experienced a case in which S-1/CDDP combination therapy proved remarkably efficacious for a rapid, extensive lymph node recurrence with metastasis into a Virchow node that had developed after resection of advanced gastric carcinoma accompanied with a marked invasion of the esophagus. The patient, a woman aged 73, underwent a total gastrectomy upon left thoracolaparotomy for a gastric carcinoma at the cardia with a 5-cm involvement of the esophagus. On day 65 post-operation, a diagnosis of Virchow node and para-aortic lymph node recurrence was made on the basis of CT scan findings. Of tumor markers checked, CEA and CA19-9 were noted to be increased to as high as 37.55 ng/mL and 3,235 U/mL, respectively. The patient received three courses of S-1/CDDP combination therapy, with a consequent noticeable contraction of the Virchow node and enlarged para-aortic lymph node. Further, she was given two courses of S-1 therapy, which resulted in normalization of tumor markers. The patient has since been on continued chemotherapy without any sign of recurrence.
