Study of Bevacizumab Plus Chemotherapy in Patients With Metastatic Colorectal Cancer
This study evaluates the relationship of biomarker expression and efficacy of bevacizumab plus chemotherapy in patients with unresectable/metastatic colorectal cancer. Before the treatment, the investigators detect the VEGF-A,VEGF-C,VEGF-D,VEGFR-1,VEGFR-2,VEGFR-3 expression in tumor tissue by IHC and detect those protein expression level in plasma by ELISA. After at least 6 weeks treatment, the investigators detect again VEGF-A,VEGF-C,VEGF-D expression level in plasma by ELISA. The aim of the study is to identify whether those biomarkers could predict Bevacizumab efficacy.

|Official Title:||Study of Bevacizumab Plus Chemotherapy in Patients With Metastatic Colorectal Cancer|
- Overall response rate [ Time Frame: 36 months ] [ Designated as safety issue: No ]During the chemotherapy,all the patients demonstrate CT scan or MR to evaluate tumor response to therapy every two cycles.According to RECIST 1.1,tumor response was recorded.
- progression free survival [ Time Frame: 36 months ] [ Designated as safety issue: No ]The start time point was defined as when patients receive the first cycle chemotherapy.The end time point was defined as When tumor response to therapy was evaluated as PD according to RECIST 1.1 or patients die for any reason.
- overall survival [ Time Frame: 36 months ] [ Designated as safety issue: No ]From the time patients receive the first cycle chemotherapy to the time they die for any reason.
- Number of Participants with Adverse Events [ Time Frame: 36 months ] [ Designated as safety issue: Yes ]Every cycle we demonstrate routine blood test,routine urine test,routine stool test,blood biochemical test.We recommend patients take blood pressure at least twice a week during the therapy.If needed,patients also need have electrocardiogram test and echocardiography.We will evaluate the toxicity according to CTCAE4.0
