Well, this disease is refractive to chemo and adapts quite soon to traditional treatments. My dad got 8 rounds of maxi-chop and 4 rounds of RICE. These treatments gave him PR, but after that nothing helped.
Your disease seems to be aggressive too. I would consider treatments like Zevalin/Bexxar, Claridibine, Velcade and Revlimid. FCM-R and DHAP are good stuff too, but those are rough and your overall condition affects to things.
I wish you luck. Attitude means a lot fighting this devil.
