- Outcomes and prognostic factors of reduced intensity-conditioned allo-SCT (RIC allo-SCT) for multiple myeloma (MM) relapsing or progressing after prior autologous (auto)-SCT are not well defined. We performed an analysis of 413 MM patients who received a related or unrelated RIC allo-SCT for the treatment of relapse/progression after prior auto-SCT. Median age at RIC allo-SCT was 54.1 years, and 44.6% of patients had undergone two or more prior auto-SCTs. Median OS and PFS from the time of RIC allo-SCT for the entire population were 24.7 and 9.6 months, respectively. Cumulative non-relapse mortality (NRM) at 1 year was 21.5%. In multivariate analysis, CMV seronegativity of both patient and donor was associated with significantly better PFS, OS and NRM. Patient-donor gender mismatch was associated with better PFS, fewer than two prior auto-SCT was associated with better OS, and shorter time from the first auto-SCT to the RIC allo-SCT was associated with lower NRM. The results of this study identify patient and donor CMV seronegativity as the key prognostic factor for outcome after RIC allo-SCT for MM relapsing or progressing after prior auto-SCT.

- So far the impact of cytogenetics risk on outcome in the context of reduced intensity conditioning (RIC) allo-SCT has been poorly studied. We have identified 378 AML patients in first CR who underwent RIC allo-SCT from an HLA-matched sibling donor between 2000 and 2007 reported to the European Group for Bone and Marrow Transplantation and for whom detailed cytogenetics data were available (good risk: n = 21; intermediate risk: n = 304; and poor risk: n = 53). With a median follow-up of 24 months (range: 1-93), 2-year non-relapse mortality, relapse rate (RR), leukemia-free survival (LFS) and OS were 14%, 31%, 55% and 61%, respectively. Cytogenetics was significantly associated with RR (good risk: 10%; intermediate risk: 28%; and poor risk: 55% at 2 years, Pandlt;0.0001) and LFS (good risk: 64%; intermediate risk: 57%; and poor risk: 38% at 2 years, P = 0.003). In a multivariate analysis, RR and LFS were significantly higher and lower, respectively, in the high-risk cytogenetics group (P = 0.001, P = 0.004) and in patients with a higher WBC at diagnosis (andgt;10 x 10(9)/L) (Pandlt;0.001, P = 0.004). As documented in the setting of myeloablative allo-SCT, patients with poor cytogenetics had increased RR and decreased LFS after RIC allo-SCT, requiring new prospective strategies to improve results in this subgroup.

- To describe outcomes, treatment and prognostic factors that influence survival of adult patients with acute lymphoblastic leukemia (ALL), who relapsed after allogeneic hematopoietic cell transplantation (HCT), we retrospectively analyzed 465 ALL adult patients from European Group for Blood and Marrow Transplantation (EBMT) centers who relapsed after a first HCT performed in complete remission (CR1 65%, CR2/3 35%). Salvage treatments were: supportive care (13%), cytoreductive therapy (43%), donor lymphocyte infusion without or with prior chemotherapy (23%) and second HCT (20%). Median time from HCT to relapse was 6.9 months, median follow-up was 46 months and median survival after relapse was 5.5 months. Estimated 1-, 2- and 5-year post-relapse survival was 30 +/- 2%, 16 +/- 2% and 8 +/- 1%, respectively. In a multivariate analysis, adverse factors for survival were: late CR (CR2/3) at transplant (P<0.012), early relapse after transplant (<6.9 months, P <0.0001) and peripheral blast percent at relapse (P <0.0001). On the basis of multivariate model for survival, three groups of patients were identified with estimated 2 year survival of 6 +/- 2, 17 +/- 3 and 30 +/- 7%. Outcome of ALL patients relapsing after HCT is dismal and there is a need for new therapies. Our study provides the standard expectations in ALL relapse and may help in the decision of post-relapse therapy.
