A 61-year-old man with the chief complaint of pressure with swallowing was referred to our hospital with type 3 cardiac gastric cancer. Gastrofiberscope showed type 3 cardiac cancer with esophageal invasion. On the abdominal computed tomography, there was evidence of lymph node swelling in the lesser curvature and multiple liver metastases. Blood tumor markers were elevated: CEA 200ng/mL, CA19-9 2,490 U/mL. He was diagnosed as unresectable advanced gastric cancer UE-circ, type-3, C-T3N2H1P0M1, Stage IV. A biopsy revealed adenocarcinoma (tub2-por1). We started bi-weekly docetaxel and S-1 combination chemotherapy (DOC 40 mg/m2 day 1, 14, S-1 80mg/m2 day 1-7, 14-21). After completion of the first course of this combination therapy, his feeling of pressure was relieved and CT showed reduction of multiple liver lesions and lymph node metastases, indicating partial response. No regrowth was seen for 7 courses of the therapy. Regarding toxicity, grade 2 nausea and grade 1 nail pain were observed. After 7 courses, because of serum CEA elevation, bi-weekly CPT-11/CDDP therapy (CPT-11 60 mg/m2, CDDP 30 mg/m2) was administered followed by weekly PTX therapy (65 mg/m2 day 1, 7, 14; total of 4 weeks). To date, 17 months after administration of chemotherapy, he has been treated on an outpatient basis. Bi-weekly DOC/S-1 therapy can be novel antitumor therapy which can be conducted safely in an outpatient setting for advanced gastric cancer.
