9. Lesions ,measurable and/or unmeasurable,at least one,can be assessed by imaging during the baseline and follow-up measurement.

   • Localized mass in gastric or Gastroesophageal Junction belongs to unmeasurable Lesions.

12. Abnormal coagulation function (INR > 1.5×ULN, APTT > 1.5×ULN), with tendency of bleed;
13. Has symptom of brain metastases and the tendency out of control,but imaging confirmed is not required.If steady dose of Glucocorticoid is necessary for the treatment,the administration should be started >4weeks prior to the study .
