Chronic graft-versus-host disease (cGVHD) is a major limitation of successful hematopoietic cell transplantation. The safety and efficacy of extracorporeal photopheresis (ECP) for 12 to 24 weeks together with standard therapy was compared with standard therapy alone in patients with cutaneous manifestations of cGVHD that could not be adequately controlled by corticosteroid treatment. The primary efficacy end point was a blinded quantitative comparison of percent change from baseline in Total Skin Score (TSS) of 10 body regions at week 12. Ninety-five patients were randomized to either ECP and standard therapy (n = 48) or standard therapy alone (n = 47). The median percentage improvement in TSS at week 12 was 14.5% for the ECP arm and 8.5% for the control arm (P = .48). The proportion of patients who had at least a 50% reduction in steroid dose and at least a 25% decrease from baseline in TSS was 8.3% in the ECP arm at week 12 and 0% in the control arm (P = .04). The nonblinded investigator assessment of skin complete or partial responses revealed a significant improvement in favor of ECP (P < .001). ECP was generally well tolerated. These results suggest that ECP may have a steroid-sparing effect in the treatment of cGVHD. Clinical trials registered at www.ClinicalTrials.gov as NCT00054613.

In this article, we report on 904 patients undergoing transplantation for follicular lymphoma. A total of 176 (19%) received allogeneic, 131 (14%) received purged autologous, and 597 (67%) received unpurged autologous transplants. Five-year treatment-related mortality (TRM) rates were 30%, 14%, and 8% and 5-year recurrence rates were 21%, 43%, and 58% after allotransplantation, purged autotransplantation, and unpurged autotransplantation, respectively. In multivariate analyses, allotransplantation had higher TRM and lower disease recurrence. Purged autotransplantation had a 26% lower recurrence risk than unpurged autotransplantation. Five-year probabilities of survival were 51%, 62%, and 55% after allogeneic, purged autotransplantation, and unpurged autotransplantation, respectively. Advanced age, prolonged interval from diagnosis to transplantation, high lactate dehydrogenase (LDH), refractory disease, bone marrow involvement, low performance scores, and transplantation between 1990 and 1993 were associated with adverse outcomes. Total body irradiation was associated with higher TRM but lower recurrence. There was no association between acute or chronic graft-versus-host disease and recurrence after allotransplantation. We conclude that both allogeneic and autologous transplantation can induce durable remissions. There may be a benefit to graft purging in autologous transplantation. The decreased recurrence after allotransplantation is offset by increased TRM. We did not detect a correlation between graft-versus-host disease (GVHD) and recurrence. Finally, outcomes of transplantation for follicular lymphoma show improvement over the past decade. (Blood. 2003;102:3521-3529)

Purpose: Adult post-transplantation lymphoproliferative disease (PTLD) has a reported 3-year overall survival (OS) of 35% to 40%. The impact of rituximab on the outcome of PTLD is not well defined.Methods: We examined the clinical features and outcomes among a large cohort of solid organ transplantation (SOT) –related patients with PTLD who were recently treated at four Chicago institutions (from January 1998 to January 2008).Results: Eighty patients with PTLD were identified who had a median SOT-to-PTLD time of 48 months (range, 1 to 216 months). All patients had reduction of immunosuppression as part of initial therapy, whereas 59 (74%) of 80 patients received concurrent first-line rituximab with or without chemotherapy. During 40-month median follow-up, 3-year progression-free survival (PFS) for all patients was 57%, and the 3-year overall survival (OS) rate was 62%. Patients who received rituximab-based therapy as part of initial treatment had 3-year PFS of 70% and OS 73% compared with 21% (P < .0001) and 33% (P = .0001), respectively, without rituximab. Notably, of all relapses, only 9% (4 of 34 patients) occurred beyond 12 months from PTLD diagnosis. On multivariate regression analysis, three factors were associated with progression and survival: CNS involvement (PFS, 4.70; P = .01; OS, 3.61; P = .04), bone marrow involvement (PFS, 2.95; P = .03; OS, 3.14; P = .03), and hypoalbuminemia (PFS, 2.96; P = .05; OS, 3.64; P = .04). Furthermore, a survival model by multivariate CART analysis that was based on number of adverse factors present (ie, 0, 1, ≥ 2) was formed: 3-year PFS rates were 84%, 66%, 7%, respectively, and 3-year OS rates were 93%, 68%, 11%, respectively (P < .0001).Conclusion: This large, multicenter, retrospective analysis suggests significantly improved PFS and OS associated with early rituximab-based treatment in PTLD. In addition, clinical factors at diagnosis identified patients with markedly divergent outcomes.

Background: Because of high single-agent activity and modest toxicity, we hypothesized the combination of gemcitabine (G), vinorelbine (V), and pegylated liposomal doxorubicin (D) would be an effective salvage therapy for Hodgkin's lymphoma (HL). Patients and methods: A total of 91 patients participated. GVD was administered on days 1 and 8 every 21 days at doses of G 1000 mg/m2, V 20 mg/m2, and D 15 mg/m2 for transplant-naive patients, and G 800 mg/m2, V 15 mg/m2, and D 10 mg/m2 for post-transplant patients. Results: The dose-limiting toxicity was mucositis for the transplant-naive patients and febrile neutropenia for post-transplant patients. The overall response rate (RR) for all patients was 70% [95% confidence interval (CI) 59.8, 79.7], with 19% complete remissions. The 4-year event-free and overall survival rates in transplant-naive patients treated with GVD followed by autologous transplant were 52% (95% CI 0.34, 0.68) and 70% (95% CI 0.49, 0.84), and in the patients in whom prior transplant failed, these were 10% (95% CI 0.03, 0.22) and 34% (95% CI 0.17, 0.52), respectively. Conclusions: GVD is a well-tolerated, active regimen for relapsed HL with results similar to those reported for more toxic regimens. High RRs in patients in whom prior transplant failed confirms this regimen's activity even in heavily pretreated patients.

The incidence, characteristics, risk factors for, and impact of chronic graft-vs-host disease (GVHD) were evaluated in a consecutive series of 116 evaluable HLA-identical blood stem cell transplant recipients. Minimum follow-up was 18 months. Limited chronic GVHD occurred in 6% (95% confidence interval [CI], 0%-13%), and clinical extensive chronic GVHD in 71% (95% CI, 61%-80%). The cumulative incidence was 57% (95% CI, 48%-66%). In univariate analyses, GVHD prophylaxis other than tacrolimus and methotrexate, prior grades 2 to 4 acute GVHD, use of corticosteroids on day 100, and total nucleated cell dose were significant risk factors for clinical extensive chronic GVHD. On multivariate analysis, GVHD prophylaxis with tacrolimus and methotrexate was associated with a reduced risk of chronic GVHD (hazard ratio [HR], 0.35; P = .001), whereas the risk was increased with prior acute GVHD (HR, 1.67;P = .046). When adjusted for disease status at the time of transplantation, high-risk chronic GVHD had an adverse impact on overall mortality (HR, 6.6; P < .001) and treatment failure (HR, 5.2; P < .001) at 18 months. It was concluded that there is a substantial rate of chronic GVHD after HLA-identical allogeneic blood stem cell transplantation, that clinical factors may alter the risk of chronic GVHD, and that high-risk chronic GVHD adversely affects outcome.
