Second auto-SCT is safe and effective salvage therapy for relapsed multiple myeloma.

Therapeutic options for patients with multiple myeloma whose disease has relapsed after a prior auto-SCT include novel biologic therapies, traditional chemotherapy or a second transplant, with no clear standard of care. Few published studies address the safety and efficacy of a second auto-SCT for relapsed disease. We reviewed the Abramson Cancer Center experience with salvage auto-SCT for relapsed multiple myeloma. Forty-one patients had received a salvage auto-SCT at our institution; the median time between transplants was 37 months (range 3–91). The overall response rate in assessable patients was 55%, and treatment-related mortality was 7%. With a median follow-up time of 15 months, the median PFS was 8.5 months and the median overall survival (OS) was 20.7 months. In a multivariate analysis of OS, independent prognostic factors were ⩾5 prior lines of therapy and time to progression after initial auto-SCT of ⩽12 months. We conclude that in well-selected patients, salvage auto-SCT is safe and effective for relapsed myeloma.

Gemtuzumab ozogamicin (Mylotarg) monotherapy for relapsed AML after hematopoietic stem cell transplant: efficacy and incidence of hepatic veno-occlusive disease

Gemtuzumab ozogamicin (GO) (Mylotarg, CMA-676) is a novel chemotherapeutic agent consisting of an anti-CD33 monoclonal antibody linked to calicheamicin, and is associated with a 30% response rate in patients with CD33-positive acute myeloid leukemia (AML) in first relapse. GO therapy has a 20% incidence of grade 3 or 4 hepatotoxicity, and has recently been associated with hepatic veno-occlusive disease (VOD). The efficacy and toxicity of GO in patients with AML who have relapsed after hematopoietic stem cell transplant (HSCT) is unknown, as this population was largely excluded from phase II studies. We reviewed the outcomes of eight consecutive patients with AML who received GO following relapse after HSCT. Two (25%) had responses to GO. One patient, who had had two previous HSCT and prior hyperbilirubinemia, developed severe VOD and died 14 days after GO therapy. The other seven patients did not meet diagnostic criteria for VOD. We conclude that GO can be safe and effective in patients who relapse following HSCT, but that caution is warranted in patients with multiple risk factors for VOD.

Transfer of influenza vaccine–primed costimulated autologous T cells after stem cell transplantation for multiple myeloma leads to reconstitution of influenza immunity: results of a randomized clinical trial

Severe immune deficiency follows autologous stem cell transplantation for multiple myeloma and is associated with significant infectious morbidity. This study was designed to evaluate the utility of a pretransplantation vaccine and infusion of a primed autologous T-cell product in stimulating specific immunity to influenza. Twenty-one patients with multiple myeloma were enrolled from 2007 to 2009. Patients were randomly assigned to receive an influenza-primed autologous T-cell product or a nonspecifically primed autologous T-cell product. The study endpoint was the development of hemagglutination inhibition titers to the strain-specific serotypes in the influenza vaccine. Enzyme-linked immunospot assays were performed to confirm the development of influenza-specific B-cell and T-cell immunity. Patients who received the influenza-primed autologous T-cell product were significantly more likely to seroconvert in response to the influenza vaccine (P = .001). Seroconversion was accompanied by a significant B-cell response. No differences were observed in the global quantitative recovery of T-cell and B-cell subsets or in global T-cell and B-cell function. The provision of a primed autologous T-cell product significantly improved subsequent influenza vaccine responses. This trial was registered at www.clinicaltrials.gov as #NCT00499577.

Long-term event-free survivors after high-dose therapy and autologous stem-cell transplantation for low-grade follicular lymphoma

Summary:Although follicular lymphoma (FL) is generally responsive to conventional-dose chemotherapy, improved survival in patients with this disease has been difficult to demonstrate. High-dose chemo/radiotherapy followed by autologous stem-cell transplantation (ASCT) can improve response rates, although its effects on survival remain controversial. Between 1990 and 2003, we transplanted 49 patients with low-grade FL at our institution. Twenty-two patients (45%) had undergone histologic transformation at the time of ASCT. In all, 44 patients (90%) had relapsed disease and five patients (10%) were resistant to chemotherapy at the time of transplantation. After ASCT, 30 patients (61%) were in complete remission (CR). The median overall survival (OS) has not been reached, while the median event-free survival (EFS) is 2.4 years. At a median follow-up of 5.5 years (longest 12.4 years), a plateau has been reached with 56% of patients remaining alive, and 35% event-free. ASCT was well tolerated except for two (4%) treatment-related deaths. In multivariable analysis, CR after ASCT and age less than 60 years are the best predictors of EFS and OS. ASCT is thus a safe therapeutic approach in FL, resulting in long-term EFS and OS for some patients, even with transformed disease.

Steroid-associated side effects in patients with multiple myeloma: consensus statement of the IMF Nurse Leadership Board.

Steroids have been the foundation of multiple myeloma therapy for more than 30 years and continue to be prescribed as single agents and in combination with other antimyeloma drugs, including novel therapies. Steroids cause a wide range of side effects that affect almost every system of the body. Identification and prompt management of the toxicities contribute to the success of steroid-containing antimyeloma regimens. By following patients carefully and educating them and their caregivers, nurses can promote adherence to therapy and improve quality of life. The International Myeloma Foundations Nurse Leadership Board developed this consensus statement for the management of steroid-associated side effects to be used by healthcare providers in any medical setting.

Stem cell collection in patients with multiple myeloma: impact of induction therapy and mobilization regimen

Lenalidomide is an active treatment for multiple myeloma (MM) and is increasingly used as part of the initial treatment of this disease. Recent reports have suggested decreases in the number of CD34+ cells collected and increases in the failure rate among patients whose initial therapy contained lenalidomide when mobilized with G-CSF alone. A retrospective data analysis of 364 patients with MM who underwent stem cell mobilization and attempted harvest at the Hospital of the University of Pennsylvania between January 2002 and December 2007 was performed. Forty-three of the patients received lenalidomide in their induction regimen, and were mobilized with either CY and G-CSF or G-CSF alone. The number of apheresis cycles and the failure rate were lower, whereas the mean number of collected stem cells was higher in patients who were mobilized with CY and G-CSF in comparison with G-CSF alone. This suggests that lenalidomide does not prevent the harvest of adequate numbers of CD34 cells for autologous stem cell transplant, but mobilization with G-CSF and CY may be required to obtain adequate numbers of stem cells. Finally, in our study, the number of lenalidomide cycles did not correlate with stem cell yield.

Renal complications in multiple myeloma and related disorders: survivorship care plan of the International Myeloma Foundation Nurse Leadership Board.

Kidney dysfunction is a common clinical feature of symptomatic multiple myeloma. Some degree of renal insufficiency or renal failure is present at diagnosis or will occur during the course of the disease and, if not reversed, will adversely affect overall survival and quality of life. Chronic insults to the kidneys from other illnesses, treatment, or multiple myeloma itself can further damage renal function and increase the risk for additional complications, such as anemia. Patients with multiple myeloma who have light chain (Bence Jones protein) proteinuria may experience renal failure or progress to end-stage renal disease (ESRD) and require dialysis because of light chain cast nephropathy. Kidney failure in patients with presumed multiple myeloma also may result from amyloidosis, light chain deposition disease, or acute tubular necrosis caused by nephrotoxic agents; therefore, identification of patients at risk for kidney damage is essential. The International Myeloma Foundations Nurse Leadership Board has developed practice recommendations for screening renal function, identifying positive and negative contributing risk and environmental factors, selecting appropriate therapies and supportive care measures to decrease progression to ESRD, and enacting dialysis to reduce and manage renal complications in patients with multiple myeloma.

Management of Side Effects of Novel Therapies for Multiple Myeloma: Consensus Statements Developed by the International Myeloma Foundation’s Nurse Leadership Board

Nurses play an essential role in managing the care of patients with multiple myeloma, who require education and support to receive and adhere to optimal therapy. The International Myeloma Foundation created a Nurse Leadership Board comprised of oncology nurses from leading cancer centers and community practices. An assessment survey identified the need for specific recommendations for managing key side effects of novel antimyeloma agents. Myelosuppression, thromboembolic events, peripheral neuropathy, steroid toxicities, and gastrointestinal side effects were selected for the first consensus statements. The board developed recommendations for healthcare providers in any medical setting, including grading of side-effect toxicity and strategies for managing the side effects in general, with specific recommendations pertaining to the novel agents.

Autologous Hematopoietic Stem Cell Transplantation for Patients With Multiple Myeloma

Autologous hematopoietic stem cell transplantation (AHSCT) is approved for the treatment of select solid tumors, autoimmune disorders, and most hematologic malignancies. Multiple myeloma (MM) is the most common indication for AHSCT. Despite improvement in response and survival rates in the era of novel agents, AHSCT remains an important treatment option for patients with MM who are eligible. Clinical management of patients with MM requires a multidisciplinary approach that incorporates healthcare professionals in a number of clinical settings as well as caregivers and the patient. Patients about to undergo AHSCT are generally referred to tertiary care centers that specialize in ASCT. Pre- and post-transplantation treatments and long-term follow-up often are managed by a community-based referring oncologist in collaboration with the transplantation team. Oncology nurses play an integral role in the care of patients with MM in each clinical setting. This article aims to provide non-transplantation oncology nurses with guidelines for education, clinical management, and support of patients with MM undergoing AHSCT with a primary focus on the pre- and post-transplantation period.
