My Mom was just diagnosed with Lymphoma and was going to start R-CHOP for treatment. Because she is recovering from surgery, she can not start the Chemo yet, but they have started her on the Rituxan. My question is does it matter that she is getting the Rituxan without the Chemo? Are they suppose to work together, or will the Rituxan be less effective without the Chemo? Any help would be appreciated.
