<qa>  What is the randomized phase II trial to see if combining bevacizumaThis randomized phase II trial is to see if combining bevacizumab with PEG-interferon alfa-2b works in treating patients who have metastatic or unresectable carcinoid tumors. Monoclonal antibodies, such as bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or deliver cancer-killing substances to them. PEG-interferon alfa-2b may stop the growth of cancer by stopping blood flow to the tumor. Combining bevacizumab with PEG-interferon alfa-2b may kill more cancer cells
