Twenty-six patients with advanced Hodgkin's disease received a related HLA haploidentical unmanipulated BMT, following a non-myeloablative conditioning with low-dose TBI, proposed by the Baltimore ...group; GvHD prophylaxis consisted of high-dose post-transplantation CY (PT-CY), mycophenolate and a calcineurin inhibitor. All patients had received a previous autograft, and 65% had active disease at the time of BMT. Sustained engraftment of donor cells occurred in 25 patients (96%), with a median time to neutrophil recovery (>0.5 × 10(9)/L) and platelet recovery (>20 × 10(9)/L) of +18 and +23 days from BMT. The incidence of grade II-IV acute GVHD and of chronic GVHD was 24% and 8%, respectively. With a median follow-up of 24 months (range 18-44) 21 patients are alive, 20 disease free. The cumulative incidence of TRM and relapse was 4% and 31%, respectively. The actuarial 3-year survival is 77%, the actuarial 3-year PFS is 63%. In conclusion, we confirm that high-dose PT-CY is effective as prophylaxis of GVHD after HLA haploidentical BMT, can prevent rejection and does not appear to eliminate the allogeneic graft versus lymphoma effect.
Highlights • We examine the effects of age and comorbidity in a real-life series of MDS patients. • Both age and comorbidities exert a significant, independent impact on clinical outcome. • The role ...of comorbidity in predicting outcome is best described by the MDS-CI score system. • The impact of MDS-CI on outcome has particular relevance in lower-risk MDS patients.
This study evaluated the impact of a new epoetin alfa dosing regimen on quality of life (QOL), transfusion requirements, and hemoglobin (Hb) levels in 133 patients with low-risk myelodysplastic ...syndrome (MDS) and Hb < or =10 g/dl. Epoetin alfa 40,000 IU was given subcutaneously twice weekly; after 4 weeks, the dose could be reduced to 40,000 IU weekly in patients achieving erythroid response. QOL was assessed using the functional assessment of cancer therapy-anemia (FACT-An) questionnaire. FACT-An scores increased on average by 7.5 after 4 weeks and by 8.8 after 8 weeks compared with baseline. FACT-An scores were positively associated with Hb values (r=0.53, P<0.01). The mean FACT-An score increase at week 8 was 10.2 in responders and 5.6 in nonresponders. The overall erythroid response rate at week 8 was 68%: 74% in transfusion-independent patients and 59% in transfusion-dependent patients. Of all responders at week 8, response was maintained in 86% at week 12, 71% at week 16, 65% at week 20, and 54% at week 24. Treatment was generally well tolerated. Our data provide new and encouraging results regarding the benefits of 40,000 IU biweekly induction doses followed by 40,000 IU weekly in improving QOL, correcting anemia, and reducing transfusion requirements in low-risk MDS patients.
We studied the impact of cytogenetics and kind of induction/consolidation therapy on 848 adult acute myeloid leukemia (AML) patients (age 15-83). The patients received three types of ...induction/consolidation regimen: standard (daunorubicin and cytosine arabinoside (3/7); two cycles); intensive (idarubicin, cytosine arabinoside and etoposide (ICE), plus mitoxantrone and intermediate-dose Ara-C (NOVIA)); and low-dose (low-dose cytosine arabinoside). CR patients under 60 years of age, if an HLA-identical donor was available received allogeneic stem cell transplantation (allo-SCT); otherwise, as part of the program, they underwent autologous (auto)-SCT. CR rates significantly associated with 'favorable' (inv(16), t(8;21)), 'intermediate' ('no abnormality', abn(11q23), +8, del(7q)) and 'unfavorable' (del (5q), -7, abn(3)(q21q26), t(6;9), 'complex' (more than three unrelated cytogenetic abnormalities)) karyotypes (88% vs 65% vs 36%, respectively; P = 0.0001). These trends were confirmed in all age groups. On therapeutic grounds, intensive induction did not determine significant increases of CR rates in any of the considered groups, with respect to standard induction. Low-dose induction was associated with significantly lower CR rates. Considering disease-free survival (DFS), multivariate analysis of the factors examined (including karyotype grouping) showed that only age > 60 years significantly affected outcome. However, in cases where intensive induction was adopted, 'favorable' karyotype was significantly related to longer DFS (P = 0.04). This was mainly due to the favorable outcome of t(8;21) patients treated with intensive induction. Patients receiving allo-SCT had significantly longer DFS (P = 0.005); in particular, allo-SCT significantly improved DFS in the 'favorable' and 'intermediate' groups (P = 0.04 and P = 0.048, respectively). In conclusion our study could provide some guidelines for AML therapy: (1) patients in the 'favorable' karyotype group seem to have a longer DFS when treated with an intensive induction/consolidation regimen, adopted before auto-SCT instead of standard induction; this underlines the importance of reinforcement of chemotherapy, not necessarily based on repeated high-dose AraC cycles. Allo-SCT, independently of induction/consolidation therapy, should be considered an alternative treatment; (2) patients in the 'intermediate' karyotype group should receive allo-SCT; (3) patients in the 'unfavorable' karyotype group should be treated using investigational chemotherapy, considering that even allo-SCT cannot provide a significantly longer DFS, but only a trend to a better prognosis.
