I started to get some neuropathy just a few months into my first treatment, which was Thalomid. I knew it was a possibility, but I’m hopelessly optimistic, and assumed it wouldn’t happen to me. I quit taking thalidomide within 8 months, because I didn’t want the neuropathy to progress beyond a point that I thought would severely impact my quality of life.
What I ended up with is numbness in my feet and sometimes pain. It started out as a pretty intense burning feeling just three months after I started treatment in 2003. My feet felt as though they were on fire! From there, it progressed to numbness. It sort of feels like my feet aren’t my own. Shoes are no longer comfy.
After treatment with Revlimid and then Velcade, my neuropathy progressed some more. It changed a little, too. I now have some significant pain at times. I have to work with my feet up. I can’t sit at a desk, or anywhere, really, for very long. If I’m seated with my legs down for more than a half hour, I end up with pain up to my knees. I have to get my legs elevated or even lie down to get some relief.
When I first began to feel the effects of peripheral neuropathy (PN), I even had some trouble walking. I’m used to it now, so I no longer have to keep my eyes on my feet when I walk. It took a while for me to adjust.
A few days ago I was attempting a an exercise that involved hopping. It was really weird, because I didn’t really know where my feet were. I had to ask someone else if my feet even left the ground! That evening, while I was walking the dog, I tried something I hadn’t done in ages. I tried skipping, just for the heck of it. I couldn’t do it! Is that something I forgot how to do, or is the PN messing with me?
I decided to look for some information on the web, and found some facts on Livestrong.com:
What are the symptoms of neuropathy?
Peripheral neuropathy can affect the nerves which allow you to tell the position of your hands or feet, the nerves that allow you to sense hot or cold, or the nerves that carry pain sensation. The types and severity of neuropathy symptoms vary greatly. It is difficult to determine the degree of peripheral nerve injury only by the symptoms produced. Peripheral neuropathy symptoms are almost always greatest at night.
Common signs and symptoms include:
- Numbness or tingling, especially of the hands or feet
- Pain or cramping, especially of the hands , feet or calf muscles
- Sensitivity to touch or temperature
- Loss of reflexes
- Muscle wasting in the hands and feet
- Weakness, especially in the feet or hands
- Clumsiness
- Loss of balance, particularly in the dark
- Dizziness, especially when getting up from a bed or a chair
- Sexual dysfunction
Are some survivors at greater risk for neuropathy?
Neuropathy may occur from cancer or the treatment received. The following types of cancer may bring a higher risk:
- Lung
- Breast
- Ovarian
- Myeloma
- Lymphoma and Hodgkin’s disease
- Testicular
Here’s a link to the entire article: http://www.livestrong.org/site/c.khLXK1PxHmF/b.2660677/
I even found that they have a group for discussion of neuropathy secondary to drugs:

This caught my eye because I’ve been on Velcade before and never gave a second thought to whether or not I should not be consuming green tea/green tea products.

The anticancer potency of green tea and its individual components is being intensely investigated, and some cancer patients already self-medicate with this ‘miracle herb’ in hopes of augmenting the anticancer outcome of their chemotherapy. Bortezomib (Velcade®) is a proteasome inhibitor in clinical use for multiple myeloma. Here, we investigated whether the combination of these compounds would yield increased antitumor efficacy in multiple myeloma and glioblastoma cell lines in vitro and in vivo. Unexpectedly, we discovered that various green tea constituents, in particular (-)-epigallocatechin gallate (EGCG) and other polyphenols with 1,2-benzenediol moieties, effectively prevented tumor cell death induced by bortezomib in vitro and in vivo. This pronounced antagonistic function of EGCG was only evident with boronic acid-based proteasome inhibitors (bortezomib, MG-262, PS-IX), but not with several non-boronic acid proteasome inhibitors (MG-132, PS-I, nelfinavir). EGCG directly reacted with bortezomib and blocked its proteasome inhibitory function; as a consequence, bortezomib could not trigger endoplasmic reticulum stress or caspase-7 activation, and did not induce tumor cell death. Taken together, our results indicate that green tea polyphenols may have the potential to negate the therapeutic efficacy of bortezomib and suggest that consumption of green tea products may be contraindicated during cancer therapy with bortezomib.

On Sunday I drove a friend to Rocky Mount, NC to visit some friends. It was 2 hours each way, with a few hours in between. By the time I got home, my feet felt as though they were in flames and someone was beating on the soles with a hammer. From the knees down felt numb. This happens to me when I have to sit for too long. This is a result of treatment with thalidomide and Velcade. Luckily, the pain and discomfort goes away by the next morning and I’m left with the numbness in just my feet.
What is it that makes the PN so much worse while sitting?

I’ve been on Velcade & Doxil since January now, so it’s time for another update. There have been a few cycles during which I missed a dose because of a rash, shingles and a trip to Mayo.
I’ve tolerated Velcade & Doxil quite well, with the exception of the skin problems. I also have a problem with the skin on my hands, which we think comes from the Doxil (HFS). Last Friday when I had treatment, I tried a suggestion from on of my doctors. During the infusion, I held an ice pack in each hand. They call this regional cooling, and more information can be found here:
http://doxil.com/optimize_treatment/managing_side_effect.jsp
What happens to me is that the skin on my hands splits open and the result is soreness and ever-present bandaids.
During my treatment, I receive some IV dex and benadryl to help lessen the hives (rash) that appeared after my second cycle. Since I started having the premeds, the hives have been practically non-existent.
I also have Anzemet, an anti-nausea drug. I’m not really sure that I need it, but I don’t want to find out. I think the Anzemet may be responsible for a headache I get the night of treatment. When there are so many things being pumped into your vein, there’s no way to be sure.
So far, the drug combo has worked for me. My IgA and m-spikes are still not in the normal range, but my bone marrow biopsy indicates that the % of plasma cells is down to 6.2%, and it was 30% last fall after Rev/dex (20% BEFORE Rev/dex).
I plan on staying with this regimen while I think about SCT and other things, and hope that it continues to work (even slowly) while I ponder.

Here’s some advice I got about Velcade/Doxil from one of the researchers involved in early trials. I thought I’d pass it on.
With the Velcade and Doxil, have they started you on oral Vit B6? When we used to run the Phase I study of that combination, we have recommended pyridoxine (Vit B6) 200 mg by mouth daily. I think this is even over the counter but you can definitely let your local doctor be aware that you are taking this. This drug is to prevent the hand-foot syndrome which is a potential side-effect of the Doxil.
There is also the risk of neuropathy with Velcade. A patient once told me that the Velcade neuropathy (which is more of pain) is different than the Thalidomide/Revlimid neuropathy (which is more of the numbness and tingling sensation). As of this time, there is no approved treatment for neuropathy or formal studies comparing all the drugs that are being used to alleviate neuropathy. We have been using either Neurontin or Lidocaine patch.
