Guys I can speak from personal experience with this matter. I, too am in remission from acute leukaemia and like Geoff Thomas I had a stem cell transplant (Geoff is a friend of mine actually).
Whilst a stem cell transplant is the best chance of curative treatment for this disease, the word 'cure' is not thrown around too much due to the on-going trials for this disease. So I am in what's known as a "complete remission" and have been since my transplant in July 2007. Geoff too.
Whilst by all accounts the likelihood of my leukaemia (and Geoffs) returning is relatively slim, I still have not been told that I've been 'cured'. With Stan his treatment will be through chemotherapy only as he doesnt require a transplant it seems (not everyone does) and chemo throughout this first year have treatment has got him to a remission. The hardest part is keeping a patient in remission. Stan has overcome some huge hurdles so far and hopefully will now stay in a remission from here on in. He will be very closely monitored for the next year.
To get where he is now is remarkable and a true testament to his character.
