| Popis: | Autologous transplantation in CML has been a focus of interest over the last few years. Determining the indications, optimal timing and method for this procedure remains controversial. One approach has been the mobilisation of Philadelphia chromosome negative (Ph-) peripheral blood stem cells following high-dose chemotherapy as a method of purging the graft. We have described a mobilisation regimen of 7 days of hydroxyurea followed by G-CSF and have shown it to be substantially less toxic than other methods. We now report further experience with this technique in a total of 18 patients and the outcome of transplantation in seven patients using cells so-derived. Following mobilisation, approximately a third of patients had 100% Ph-collections and half had less than 50% Ph+ collections. All patients were 100% Ph+ prior to mobilisation. Six out of seven transplanted patients showed sustained engraftment and two of these patients became 18 and 34% Ph+ 3 months post-transplant. Five patients remain alive and well 13 to 25 months post-autograft. In conclusion, we have developed a well-tolerated regimen for Ph- PBSC mobilisation and have demonstrated that such cells are capable of sustained engraftment and of producing significant cytogenetic responses. |
