A 59-year-old man visited our department with the complaint of an abdominal mass. After detailed examination, he was diagnosed with cT3 (SE) N2M0, cStage III C gastric cancer and underwent a 3 course preoperative S-1/CDDP combination chemotherapy. After tumor down-staging was achieved after the 3 course combination chemotherapy, a surgery was scheduled. The patient underwent distal gastrectomy with D2 lymph node dissection. Histopathological diagnosis was M, type 1, 75 × 35 mm, papillary>moderately-differentiated tubular adenocarcinoma [pT2 (MP), ly3, v0, pN2, Stage IIB]. The patient is now treated with oral S-1 as postoperative adjuvant chemotherapy on an outpatient basis, and there are no signs of recurrence as of 1 year after the surgery. Preoperative chemotherapy appears to be a promising treatment option for gastric cancer with extensive lymph node metastasis. |
