[A complete response using TS-1 in a patient with paramesenteric lymph node recurrence of gastric cancer]

A 86-year-old male patient underwent distal gastrectomy, D2 lymph node dissection for type 2 gastric cancer. Five months after the surgery, abdominal computed tomography (CT) revealed paramesenteric vein lymph node recurrence (# 14v), 12 mm in size. TS-1 (80 mg/day) was administered for 28 days, followed by 14 days rest, as one course. A complete response was obtained after the second course. The patient has been in good health without a recurrence for 36 weeks after 5 courses. As for adverse events, leukopenia (grade 2) was observed temporarily but required no treatment.
