Hi - so sorry about your husband's troubles. I can just tell you about my father's experience with Velcade so far. And yes, everyone is different, but so far, for us, I think the Velcade itself has been a walk in the park, compared to other things i hear about.
My dad has MM -- Stage III, with a lot of bone damage in the pelvic/hip areas. He's 77 years old, but prior to this, an extremely young, on-the-go, still working, active 77. He was diagnosed officially in November of 2007 and they started him on Velcade as his initial treatment almost immediately. The standard is Velcade IV, twice a week (and they will usually put someone on a Dex/Decadron steriod pill along with it). For the first month, my dad got the Velcade twice a week. But since January, he only gets it once a week, because at the time, twice a week was really too much of a toll on him, his lack of mobility, etc (he had a severe compression fracture of the spine). As far as side effects, for him -- i would say the only thing it has caused him is occassional diarrhea. He usually gets the diarrhea about a day or two after the Velcade treatment, and then it lightens up. He does not get nauseous (they give you an anti-nausea thing in the drip beforehand). Once in a while, he may get some tingling in his leg (i am told that neuropathy is a side effect) but for him, it is practically nothing. For a while there, he was getting crazy diarrhea which i was worried about, but after much worrying and observation, i am convinced it was due to the daily Prilosec he was taking for 5 months. Once he stopped taking that, i saw a lot of improvement. Also, if your husband happens to experience a lot of diarrhea due to the Velcade, they can give you a medicine to help with that. My dad now takes a prescription pill -- it's called Lomitol, fyi. That seems to have helped his problem. As far as Velcade's effect on the cancer, it was his first course of treatment and thankfully, worked like magic, almost immediately. His numbers were crazy high when he was first diagnosed, and then within a couple of weeks -- the dropped significantly. The normal range for IGA is 70 to 400... upon diagnosis he was 3400 (!) -- and then after one round of Velcade, it dropped to 400... then after that, continues to hold around 105 - 115. Not totally gone but stable.
I have heard about some people not doing well with Velcade in other cases... some people get bad neuropathy, which you have to watch. Some people it effects their eyes/vision, some people get headaches, etc. For my dad, it's been pretty okay as far as side effects. If i'm not mistaken, I think a lot of doctors are using it now as a first line of treatment, because it seems to be very effective regarding the cancer, and also because for many, it seems fairly easy to tolerate. But as you know with this type of cancer -- everyone's case is different. My dad is now doing Velcade for almost 8 months (with short breaks/rest periods in between). He also gets Aredia (iv) once a month. He no longer takes the Dex/Steriods (was only on that for a few months). He is now very active again and thanfully, able to go out a bit and get around much better. I know it's not going to last permanently, but i thank god for Velcade and that it worked. I also see what other people go thru with regular Chemotherapy, etc and am thankful that my dad didn't have to suffer/be miserable, with that kind of treatment. Another reason why i was extrememly grateful for the Velcade -- that is covered with his insurance with no problems whatsoever, but initially, they were also going to put him on Thalidomide with it... but his insurance barely covered a tiny portion of it, and he his co-pay would have been $3800 a month -- which he could absolutely not afford. So we could not get the Thalidomide, which i thought was a 'death sentence' at the time -- but it wasn't, thanks to Velcade.
I wish you & your husband well and don't worry, things have a way of working out. I know what you mean by wanting your husband to have a 'break' and some peace for a while, i feel the same for my dad. If he had his way, he'd just like to stay home forever and pretend he's not sick!
