What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
6-month progression-free survival rate	Tumor response will be evaluated by Response Evaluation Criteria in Solid Tumors (RECIST)Guidelines version 1.1.	From date of registration to the date of disease progression or date of death from any cause, whichever came first, assessed up to 26 weeks .

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
tumor response	Efficacy evaluations: objective tumor response according to RECIST 1.1	From date of registration to the date of disease progression or date of death from any cause, whichever came first, assessed up to 26 weeks .
Overall survival	Overall survival: defined as the time from the date of first study treatment to the date of patient death, due to any cause, or to the last date the patient was known to be alive. The primary analysis population for the overall survival will be per-protocol population. The endpoint will also be analyzed in the intent-to-treat population. Kaplan-Meier estimates will be calculated for the overall survival.	Overall survival will be assessed. From date of registration until the date of death, assessed up to 60 months.
Disease control rate (Objective response rate (ORR) + stable disease ≧ 12 weeks)	Efficacy evaluations: objective tumor response according to RECIST 1.1	From date of registration to the date of disease progression or date of death from any cause, whichever came first, assessed up to 26 weeks .
Safety profile	Adverse events (AEs) will be evaluated according to the National Cancer Institute's Common Terminology Criteria for Adverse Events version 4 (CTCAE v4).All required pre-treatment and interim data should be available and the physician must have made a designation as to response if a re-evaluation has been performed and the grade of toxicity if any has occurred。	From date of registration to the date of disease progression or date of death from any cause, whichever came first, assessed up to 26 weeks .
Biomarker study	evaluated for biomarkers, including inflammatory cytokine (TGF-β, hepatocyte growth factor (HGF), interleukin (IL)-6, IL-8, IL-1, CXCL-1, Chemokine (C-X-C motif) ligand 3(CXCL-3), and stromal-derived factor (SDF)...etc). Tumor DNA will be extracted from formalin-fixed paraffin-embedded(FFPE) slides for p53, CDKN2A and AT-rich interactive domain-containing protein 1A (ARID1A) mutation which were reported to be correlated with chemotherapy resistance	From date of registration to the date of disease progression or date of death from any cause or date of unacceptable toxicity or date of patient's refusal , whichever came first, assessed up to 26 weeks .
