We prospectively treated 80 patients with relapse of malignancy or secondary myelodysplasia after autologous hematopoietic cell transplantation (AHCT) with allogeneic HCT (allo-HCT) using a reduced-intensity conditioning regimen of fludarabine 150 mg/m2 plus intravenous busulfan 6.4 mg/kg. Both matched sibling (MSD) and unrelated donors (MUD) were allowed. Patients transplanted from MUD donors received more intensive graft-versus-host disease (GVHD) prophylaxis, including rabbit antithymocyte globulin (ATG) 10 mg/kg, mycophenolate mofetil, and an extended schedule of tacrolimus. With a median follow-up of 3.1 years (0.9-5.8), treatment-related mortality (TRM) at 6 months and 2 years was 8% and 23%, respectively. Neither TRM nor the rates of acute GVHD (aGVHD) were different in those with sibling or MUD donors. Donor CD3 cell chimerism >90% at day +30 was achieved more often in patients with MUD than with matched sibling donors, 70% versus 23% (P < .0001). Median event-free suvival was higher in patients who achieved early full donor chimerism (14.2 versus 8 months, P = .0395). Allo-HCT using this reduced-intensity conditioning regimen can be performed with low TRM in patients who have received a prior AHCT. Efforts to improve early donor CD3 chimerism may improve event-free survival. © 2011 American Society for Blood and Marrow Transplantation. Source

Background: Myelodysplastic syndromes (MDS) comprise a heterogeneous group of hematologic malignancies, with an incidence rate of 3.4 cases per 100,000 in the United States. MDS affects patients predominantly over 60 years of age. As these syndromes are not well understood by many medical practitioner, patients with MDS may be underrecognized or underdiagnosed. The availability of new MDS treatment options further establishes the need to more closely assess gaps in clinical practice and underscores the necessity to develop educational activities to address those gaps. Methods: A multidisciplinary panel was convened to examine current educational needs and gaps. A group consensus approach incorporating a modified nominal group technique was utilized to prioritize and review needs identified in the pre-meeting survey and to evaluate data provided by panelists prior to the meeting. Results: The panel identified and prioritized seven educational areas of need: (1) MDS disease awareness, (2) diagnosis, (3) classification and risk stratification, (4) treatment issues, (5) referral to stem cell transplantation or new treatment protocols, (6) clinical monitoring and toxicity management, and (7) translation of new data into patient care. Conclusions: In-depth knowledge is critical to the timely diagnosis and optimal care of MDS patients. A number of key educational needs exist. Educational programs should be practical in orientation to integrate data into practice, and they should be tailored for the intended audience. In addition, an effective educational program must be easily applied by participants. Source

This multicentre, single-arm, open-label phase 2 trial investigated the efficacy and safety of lenalidomide monotherapy in patients with relapsed/refractory peripheral T-cell lymphoma (PTCL). Methods Patients received oral lenalidomide 25 mg once daily on days 1-21 of each 28-day cycle for a maximum of 24 months, until disease progression or development of unacceptable adverse events (AEs). The primary end-point was efficacy; safety was evaluated as a secondary end-point. This study was registered with ClinicalTrials.gov, number NCT00655668. Findings A total of 54 patients with PTCL were treated. The overall response rate was 22% (12 of 54), including complete response (CR) or unconfirmed CR (CRu) in 11% of patients; 31% of patients with angioimmunoblastic T-cell lymphoma (AITL) responded (CR/CRu in 15% of patients). The median progression-free survival and median response duration were 2.5 and 3.6 months, respectively, in the intent-to-treat population, and 4.6 and 3.5 months, respectively, in patients with AITL. Thrombocytopenia and neutropenia were the most common grade 3 or 4 haematological AEs, in 11 (20%) and 8 (15%) patients, respectively. Overall, 19 patients (35%) experienced at least 1 AE leading to study dose interruption or reduction (commonly neutropenia or thrombocytopenia). Serious AEs were observed in 54% of patients and 12 patients died during the study; lymphoma progression (n = 6); and acute respiratory distress syndrome, dyspnea, lung infiltration, neutropenic sepsis, pneumonia and cerebral ischaemia (n = 1 each). Interpretation Lenalidomide exhibited single-agent activity in heavily pretreated patients with PTCL, particularly in patients with AITL. Future development is warranted in specific histologies, such as AITL, and in combination with chemotherapy or other agents considered active in PTCL.

The multicentre, open-label, two-stage, single-arm, phase 2, PILLAR (PIvotaL Lymphoma triAls of RAD001)-1 study (NCT00702052) assessed the efficacy and safety of everolimus 10 mg/d in adults with confirmed mantle cell lymphoma (MCL) refractory to or intolerant of bortezomib who received ≥1 other antineoplastic agent, either separately or in combination with bortezomib. Primary endpoint was overall response rate (ORR) per investigator review according to the response criteria for malignant lymphoma. Secondary endpoints included progression-free survival (PFS), overall survival (OS) and safety. Fifty-eight patients were enrolled from August 2008-January 2011. Five partial responses were observed (ORR 8·6%; 90% confidence interval [CI] 3·5-17·3%); the study did not meet the prespecified objective of ≥8 objective responses among 57 patients. Median PFS and OS were 4·4 months (95% CI 3·5-6·1) and 16·9 months (95% CI 14·4-29·9), respectively. Grade 3/4 non-haematological toxicities occurred in 70·7% of patients. Based on laboratory values, grade 3/4 thrombocytopenia, neutropenia and anaemia occurred in 13·8%, 13·8% and 8·6% of patients, respectively. Everolimus demonstrated modest activity and acceptable tolerability in heavily pretreated patients with MCL refractory to or intolerant of bortezomib. Future studies evaluating everolimus in a less refractory population or in combination with other targeted therapies in refractory MCL are warranted. © 2014 John Wiley & Sons Ltd. Source

Hematopoietic stem cell transplantation (HSCT) plays a central role in patients with malignant and, increasingly, nonmalignant conditions. As the number of transplants increases and the survival rate improves, long-term complications are important to recognize and treat to maintain quality of life. Sexual dysfunction is a commonly described but relatively often underestimated complication after HSCT. Conditioning regimens, generalized or genital graft-versus-host disease, medications, and cardiovascular complications as well as psychosocial problems are known to contribute significantly to physical and psychological sexual dysfunction. Moreover, it is often a difficult topic for patients, their significant others, and health care providers to discuss. Early recognition and management of sexual dysfunction after HSCT can lead to improved quality of life and outcomes for patients and their partners. This review focuses on the risk factors for and treatment of sexual dysfunction after transplantation and provides guidance concerning how to approach and manage a patient with sexual dysfunction after HSCT. © 2015 American Cancer Society.
