Hello Lillian , I had two rounds of DTPACE (with velcade thrown in for good luck ) 3 years ago after my initial treatments (CTD, VTD ) didn’t work . Since then I have been in remission and on Revlimid maintenance so tell your husband to hang in there . I found the worst part of DTPACE was being tied to the drip pump for 96 hours non stop . Good Luck .
