Do you include bevacizumab with chemotherapy in patients with metastatic colon cancer with an intact primary tumor who have intermittent obstructive symptoms?

I agree with Dr. @Dr. First Last. If I am worried that obstruction could happen but we are not at the point where we need to pause for a diversion, I will start chemo without bevacizumab for the first 2 to 3 doses - so that we get that response that he mentions - and then I can add without being too...
