I have had nonhodgkins lymphoma for two and a half years, will rituximab and obintzumab help me?

Maybe: The only way to know is to get a full evaluation from a hematologist. There are too many factors that go into making a recommendation regarding treatment of nhl to be able to get a personalized answer thru healthtap. If you are not confident with the recommendations you have received so far a second (or third) opinion would be in order.
