WHEN TO OFFER TRANSPLANTATION IN CLL<br />

The results <strong>of</strong> phase II studies <strong>of</strong> RIC allogeneic SCT<br />

suggest that whereas patients with refractory disease may<br />

respond to the GVL effect, optimal outcome will be achieved<br />

by consideration <strong>of</strong> transplant for those patients with highrisk<br />

disease before they become truly refractory and those<br />

patients in whom minimal disease state cannot be achieved.<br />

We have demonstrated that CLL cells are inherently immunosuppressive<br />

even to allogeneic donor T cells, and this may<br />

explain why better results are obtained when patients<br />

receive RIC allogeneic SCT with low tumor bulk, which can<br />

only be achieved if patients are <strong>of</strong>fered this approach before<br />

truly refractory disease occurs. 42<br />

Conclusion<br />

SCT has a role to play in selected patients with CLL, with<br />

major focus now on the use <strong>of</strong> RIC allogeneic SCT. Future<br />

approaches to the management <strong>of</strong> this disease must take<br />

into account the balance between the increased morbidity<br />

and mortality <strong>of</strong> SCT in CLL with the curative potential that<br />

these approaches potentially <strong>of</strong>fer, in the setting <strong>of</strong> the<br />

outcome improvements that can now be seen using chemoimmunotherapy.<br />

Although RIC allogeneic SCT results in<br />

high response rates and eradication <strong>of</strong> polymerase chain<br />

reaction–detectable MRD and is potentially curative, the<br />

follow-up <strong>of</strong> most clinical trials remains too short to assess<br />

whether SCT can really cure CLL. In the absence <strong>of</strong> any<br />

other treatment modalities currently capable <strong>of</strong> improving<br />

outcome in this disease, SCT should be considered as a<br />

treatment approach for younger patients with high-risk CLL<br />

early in the course <strong>of</strong> the disease, ideally in the setting <strong>of</strong><br />

well-designed clinical trials assessing the treatment’s effect<br />

on outcome in these patients. Several such trials are underway.<br />
