First let me say I have and still use these supplements for over a year now, I still had tumor growth and am now currently on 6 rounds of Rituxan and 6 CHOPS, I have good results from the Rituxan and problems with the CHOPS including calcium leaching from my bones. There are clinical trials at UCSD Medical University in San Diego on their web site for B cell NHL which is also what I have. I have gone for an initial consultation already and if my current treatment shows no improvement on this months CAT SCANS I will be making arrangements for the UCSD clinical trial. My choice after that will be The Treatment Centers of America in Seattle WA. Good luck!
