No prior chemotherapy for gastric cancer. Patients with recurrent cancer after 180 days from the last day of preoperative or postoperative adjuvant chemotherapy are eligible for enrollment. 3.
Patients who are judged to be eligible for combination therapy with SOX and nivolumab by the physician in charge of the patient. 4.
4. the S-1 dose obtained from the BBT formula nomogram (page X) is increased from the starting dose described in the package insert.
5. the patient is at least 18 years of age at the time consent is obtained.
6. ECOG-Performance Status is 0,1
7. Capable of oral intake
8. Have at least one evaluable lesion on contrast-enhanced CT (chest, abdomen, pelvis: slice thickness less than 7 mm) within 28 days prior to registration.
