Hi Jason,
Because we all react so differently to the various drugs, it is very difficult to predict the actual length of your treatment period or the specific number of treatment cycles you will have to undertake. It all depends on how well you respond to the chemotherapy and your tolerability to the drugs.
My first treatment in 2010 consisted of four cycles of CDT followed by an stem cell transplant (SCT) which took a total time of 5 months. However my relapse treatment in 2015/16 took 8 cycles of VCD followed by an Sct which took a longer time of 12 months. The relapse treatment took longer due to a number of factors including a short break required due to low blood levels, another break due to flu virus, peripheral neuropathy, my myeloma taking longer to respond and waiting lists for STC.
The aim of your VTD chemotherapy will be to reduce your myeloma levels by as much as possible prior to the STC process. At the end of each cycle of treatment, you meet with your consultant to monitor your bloods, myeloma levels and your progress, together with discussing how you are coping with the treatment and any side effects you are experiencing. Your consultant will then decide on the best way forward which may be altering your treatment/dose of medications/length of each cycle/number of cycles, etc.
I hope your treatment is successful.
Best wishes
Jan
