*If the patient received adjuvant chemotherapy and the diasese recurred within 6 manths after the completion,the patient is excluded from this study.
(3) Age of 20-80 years at time of enrollment;
(4) Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1;
(5) Metastatic of recurrent pancreatic cancer refractory to first-line gemcitabin-based chemotherapy;

*Ajuvant chemotherapy with irinotecan and/or fluorouracil is permitted.
(2) History of malignancy (except for adequately treated carcinoma in situ, non-invasive cancer) within 2 years prior to study entry except if the patient has undergone potentially curative therapy with no evidence of that disease recurrence for 2 years;
(3) Evidence of uncontrolled,active infection,requiring anti-infectious treatment,except for viral hepatitis;
(4) Any chemotherapy for pancreatic cancer within 14days prior to the initiation of study treatment;
(5) Any major surgery*,radiotherapy, immunotherapy,or investigational drugs within 28 days prior to the initiation of study treatment;*In cases with exploratory laparotomy,intestinal bypass surgery,billiary bypass surgery ,or endoscopic resection, study entry is permitted if 14 days have passed.
