Hi Justine, i have to admit, that I find the Australian health care system to be a bit confusing, but I did notice on the Australian Health care site that Revlimid (lenalidomide) is approved in Australia, but has restrictions surrounding it's uses, as does Velcade.
Revlimid is in the same type of drug category as Thalidomide. Thalidomide was found to help in myeloma more than a decade ago. It is an immunomodulatory drug, and it causes the little blood capillaries to shut down, starving the myeloma. It was originally an anti-nausea drug used in pregnancy, but was pulled off the market in 1961 when it was found to cause birth defects. Revlimid is similar to that but seems more effective against myeloma, and causes less neuropathy too. Both of those drugs are made by the same drug company, and the distribution is tightly controlled since there is that risk of birth defects.
Velcade is a different type of drug, a proteasome inhibitor. This type of drug interferes with the 'garbage disposal' mechanism of the cancer cells, causing them to choke on their own discarded proteins, instead of recycling the protein into the component amino acids.
If you have time you could look up these topics in the information booklets available online from the INTernational Myeloma Foundation (IMF). Probably you can get into more conversations with the oncologists if you learn more too! I wonder how much 'wiggle room' there is in your health care system, to work around these stringent regulations?, eg. how many cycles of Velcade are allowed?
I hope that everything starts to turn around for you soon. FYI, I also had about 50% myeloma cells in my marrow at dx, and I wasn't being melodramatic to be really upset about that!
