Hi Charlotte
I was diagnosed woth solitary bony plasmacytoma in my sternum in May 2011. I had steroids and 5 wks of radiotherapy. Following treatment there was no paraprotein trace but I still had high serum free kappa light chains. These gradually reduced at each blood test but it took until August 2012 for them to return to normal levels. My PET scan in March 2012 showed there was still some activity in the sternum but my Haem felt this was more likely to be signs of bony healing over actice tumour cells (although nobody can be sure). She stills reminds me that I have had definitive treatment and we should watch and wait. I had a second opinion on this and he agreed. I have just had a re-staging MRI so we'll see what that shows.
In terms of the future, I have been told that I have a 50/50 chance of progression to mm, but this decreases after 5yrs and then peaks again at 15 yrs. I am 34 and really hope I don't progress.
I'm really pleased that life is almost back to normal for you. I still have a lot of muscular pain in my back and shoulders, plus upper body weakness ( they think because of the large size of the tumour). The bony pain has reduced in the last few months.
I've stopped looking for stats now as it caused far too many sleepness nights, as I realise there are so few of us, but still get really anxious about test results before each appointment.
Anyway good luck
