Article: Risk factors for relapse after complete remission with high-dose therapy for multiple myeloma.
[show abstract] [hide abstract]
ABSTRACT: Complete remission (CR) is an important surrogate for long-term survival for patients with multiple myeloma. However, most patients achieving CR eventually relapse and die from their disease. To better define the predictors of relapse, we conducted a retrospective review of outcomes for patients who achieved CR after autografting at our institution. From January 1990 to December 2002, among >400 patients transplanted, 81 (54 males and 27 females) achieved CR. With a median follow up of 58 months for all surviving patients, the 5-year progression-free survival (PFS) was 33% [95% confidence interval (CI) = 23 - 44] and 5-year overall survival (OS) was 67% (95% CI = 54 - 77). Median PFS was 37 months and median OS has not yet been reached. On multivariate analysis, high tumor mass at diagnosis emerged as a predictor of poor outcome. We conclude that high tumor mass at diagnosis predicts a significantly shorter remission duration for myeloma patients undergoing autografting.Leukemia and Lymphoma 07/2006; 47(7):1360-4. · 2.58 Impact Factor -
Article: Hemorrhagic cystitis after allogeneic hematopoietic stem cell transplantation: donor type matters.
[show abstract] [hide abstract]
ABSTRACT: Hemorrhagic cystitis (HC) remains a common complication of allogeneic blood and marrow transplantation. Previous analyses of risk factors for this complication were performed in heterogeneous populations, with dissimilar diagnosis and conditioning regimens. We postulated that HC is more prevalent in matched unrelated donor (MUD) and unrelated cord blood (UCB) transplantations than in matched related donor (MRD) transplantations. We performed a retrospective study on 105 acute lymphocytic leukemia patients treated with 12 Gy total body irradiation-based regimens and allogeneic transplants (MUD, n = 38; UCB, n = 15; mismatched related, n = 20; MRD, n = 32). HC occurred in 16% of patients receiving MRD transplants, 30% of recipients of mismatched related, and 40% of MUD or UCB transplants (hazard ratio 2.9, 95% CI 1.0-7.9 for the comparison of MRD versus MUD). The excessive rate of HC among MUD and UCB patients became evident after the first 30 days after transplantation. Recipients younger than 26 years had a significantly higher incidence of HC (HR 2.5, 95% CI 1.1-5.8). This donor type and age effect was independent of platelet engraftment, development of graft-versus-host disease (GVHD), source of stem cells, use of anti-thymocyte globulin (ATG) or cyclophosphamide in the regimen, steroid use, or stem cell source. We concluded that HC is more prevalent in MUD and UCB transplantations.Blood 07/2004; 103(12):4674-80. · 9.90 Impact Factor
