Outcome with lenalidomide plus dexamethasone followed by early autologous stem cell transplantation in patients with newly diagnosed multiple myeloma on the ECOG-ACRIN E4A03 randomized clinical trial: long-term follow-up
In Eastern Cooperative Oncology Group-ACRIN E4A03, on completion of four cycles of therapy, newly diagnosed multiple myeloma patients had the option of proceeding to autologous peripheral blood stem cell transplant (ASCT) or continuing on their assigned therapy lenalidomide plus low-dose dexamethasone (Ld) or lenalidomide plus high-dose dexamethasone (LD). This landmark analysis compared the outcome of 431 patients surviving their first four cycles of therapy pursuing early ASCT to those continuing on their assigned therapy. Survival distributions were estimated using the Kaplan–Meier method and compared with log-rank test. Ninety patients (21%) opted for early ASCT. The 1-, 2-, 3-, 4- an
Post-Transplant Outcomes in High-Risk Compared with Non-High-Risk Multiple Myeloma: A CIBMTR Analysis.
Conventional cytogenetics and interphase fluorescence in situ hybridization (FISH) identify high-risk multiple myeloma (HRM) populations characterized by poor outcomes. We analyzed these differences among HRM versus non-HRM populations after upfront autologous hematopoietic cell transplantation (autoHCT). Between 2008 and 2012, 715 patients with multiple myeloma identified by FISH and/or cytogenetic data with upfront autoHCT were identified in the Center for International Blood and Marrow Transplant Research database. HRM was defined as del17p, t(4;14), t(14;16), hypodiploidy (-Y) or chromosome 1 p and 1q abnormalities; all others were non-HRM. Among 125 HRM patients (17.5%), induction with bortezomib and immunomodulatory agents (imids) was higher compared with non-HRM (56% versus 43%, P \u3c .001) with similar pretransplant complete response (CR) rates (14% versus 16%, P .1). At day 100 post-transplant, at least a very good partial response was 59% in HRM and 61% in non-HRM (P = .6). More HRM patients received post-transplant therapy with bortezomib and imids (26% versus 12%, P = .004). Three-year post-transplant progression-free (PFS) and overall survival (OS) rates in HRM versus non-HRM were 37% versus 49% (P \u3c .001) and 72% versus 85% (P \u3c .001), respectively. At 3 years, PFS for HRM patients with and without post-transplant therapy was 46% (95% confidence interval [CI], 33 to 59) versus 14% (95% CI, 4 to 29) and in non-HRM patients with and without post-transplant therapy 55% (95% CI, 49 to 62) versus 39% (95% CI, 32 to 47); rates of OS for HRM patients with and without post-transplant therapy were 81% (95% CI, 70 to 90) versus 48% (95% CI, 30 to 65) compared with 88% (95% CI, 84 to 92) and 79% (95% CI, 73 to 85) in non-HRM patients with and without post-transplant therapy, respectively. Among patients receiving post-transplant therapy, there was no difference in OS between HRM and non-HRM (P = .08). In addition to HRM, higher stage, less than a CR pretransplant, lack of post-transplant therapy, and African American race were associated with worse OS. In conclusion, we show HRM patients achieve similar day 100 post-transplant responses compared with non-HRM patients, but these responses are not sustained. Post-transplant therapy appeared to improve the poor outcomes of HRM
Blood Parasites from Birds of the Lake Okoboji Region, Iowa
Hematozoa are reported from 171 birds, representing 7 orders of 20 families and 33 species, all collected in Dickinson County, northwest Iowa, with the majority of animals being collected at the Iowa Lakeside Laboratory, Milford, Iowa. Blood parasites were observed in 67 birds (39.2%), with an incidence as follows: Haemoproteus sp., 45 (26.3%); Leucocytozoon sp., 19 (11.1%); Plasmodium sp., 4 (2.3%); Trypanosoma 3 (1.7%); and microfilariae, 29 (16.9%). An evaluation of these results indicates a dramatic decrease in the incidence of blood parasites later in the summer. The presence of parasites early in the spring is considered to be a function of relapse in birds returning to the area to build nests and to reproduce. The subsequent decrease in incidence of parasitized birds occurs as the infections run their course and become latent. A species of Plasmodium isolated from a blue jay (Cyanocita cristata) was found to be highly pathogenic, since the natural host as well as two other blue jays with induced blood infections died, with over 60% of their erythrocytes being parasitized. Using gametocyte morphology, the number of merozoites in mature schizonts and the punctiform appearance of pigment, the parasite was considered to be P. relictum. The blue jay appears to be a new host record for this parasite, at least in Iowa
Interventions for preventing oral mucositis for patients with cancer receiving treatment
Interventions for preventing oral mucositis for patients with cancer receiving treatmentTreatment for cancer (including bone marrow transplant) can cause oral mucositis (severe ulcers in the mouth). This painful condition can cause difficulties in eating, drinking and swallowing, and may also be associated with infections which may require the patient to stay longer in hospital. Different strategies are used to try and prevent this condition, and the review of trials found that some of these are effective. Two interventions, cryotherapy (ice chips) and keratinocyte growth factor (palifermin®) showed some benefit in preventing mucositis. Sucralfate is effective in reducing the severity of mucositis, and a further seven interventions, aloe vera, amifostine, intravenous glutamine, granulocyte‐colony stimulating factor (G‐CSF), honey, laser and antibiotic lozenges containing polymixin/tobramycin/amphotericin (PTA) showed weaker evidence of benefit. These were evaluated in patients with different types of cancer, undergoing different types of cancer treatment. Benefits may be restricted to the disease and treatment combinations evaluated
Guidelines for screening and management of late and long-term consequences of myeloma and its treatment
A growing population of long-term survivors of myeloma is now accumulating
the ‘late effects’ not only of myeloma itself, but also of several lines of
treatment given throughout the course of the disease. It is thus important to
recognise the cumulative burden of the disease and treatment-related toxicity
in both the stable and active phases of myeloma, some of which is unlikely to
be detected by routine monitoring. We summarise here the evidence for the
key late effects in long-term survivors of myeloma, including physical and
psychosocial consequences (in Parts 1 and 2 respectively), and recommend
the use of late-effects screening protocols in detection and intervention. The
early recognition of late effects and effective management strategies should
lead to an improvement in the management of myeloma patients, although
evidence in this area is currently limited and further research is warranted
Levofloxacin prophylaxis in patients with newly diagnosed myeloma (TEAMM): a multicentre, double-blind, placebo-controlled, randomised, phase 3 trial.
BACKGROUND: Myeloma causes profound immunodeficiency and recurrent, serious infections. Around 5500 new cases of myeloma are diagnosed per year in the UK, and a quarter of patients will have a serious infection within 3 months of diagnosis. We aimed to assess whether patients newly diagnosed with myeloma benefit from antibiotic prophylaxis to prevent infection, and to investigate the effect on antibiotic-resistant organism carriage and health care-associated infections in patients with newly diagnosed myeloma. METHODS: TEAMM was a prospective, multicentre, double-blind, placebo-controlled randomised trial in patients aged 21 years and older with newly diagnosed myeloma in 93 UK hospitals. All enrolled patients were within 14 days of starting active myeloma treatment. We randomly assigned patients (1:1) to levofloxacin or placebo with a computerised minimisation algorithm. Allocation was stratified by centre, estimated glomerular filtration rate, and intention to proceed to high-dose chemotherapy with autologous stem cell transplantation. All investigators, patients, laboratory, and trial co-ordination staff were masked to the treatment allocation. Patients were given 500 mg of levofloxacin (two 250 mg tablets), orally once daily for 12 weeks, or placebo tablets (two tablets, orally once daily for 12 weeks), with dose reduction according to estimated glomerular filtration rate every 4 weeks. Follow-up visits occurred every 4 weeks up to week 16, and at 1 year. The primary outcome was time to first febrile episode or death from all causes within the first 12 weeks of trial treatment. All randomised patients were included in an intention-to-treat analysis of the primary endpoint. This study is registered with the ISRCTN registry, number ISRCTN51731976, and the EU Clinical Trials Register, number 2011-000366-35. FINDINGS: Between Aug 15, 2012, and April 29, 2016, we enrolled and randomly assigned 977 patients to receive levofloxacin prophylaxis (489 patients) or placebo (488 patients). Median follow-up was 12 months (IQR 8-13). 95 (19%) first febrile episodes or deaths occurred in 489 patients in the levofloxacin group versus 134 (27%) in 488 patients in the placebo group (hazard ratio 0·66, 95% CI 0·51-0·86; p=0·0018. 597 serious adverse events were reported up to 16 weeks from the start of trial treatment (308 [52%] of which were in the levofloxacin group and 289 [48%] of which were in the placebo group). Serious adverse events were similar between the two groups except for five episodes (1%) of mostly reversible tendonitis in the levofloxacin group. INTERPRETATION: Addition of prophylactic levofloxacin to active myeloma treatment during the first 12 weeks of therapy significantly reduced febrile episodes and deaths compared with placebo without increasing health care-associated infections. These results suggest that prophylactic levofloxacin could be used for patients with newly diagnosed myeloma undergoing anti-myeloma therapy. FUNDING: UK National Institute for Health Research
Supportive care in multiple myeloma
Multiple myeloma is one of the most commonly diagnosed blood cancers. Due to the introduction of new therapies in recent years, there has been significant progress in treating myeloma. Even so, with the introduction of new groups of drugs, there have been some adverse events. In addition to anti-myeloma treatment, patients require supportive therapies. This article presents the principles of supportive treatment in emergencies and discusses the toxicity associated with the use of new groups of drugs
Clinical implications of cytogenetic and molecular aberrations in multiple myeloma
Multiple myeloma (MM) is an incurable haematological malignancy affecting approximately 7:100,000 people. Monoclonal gammopathy of undetermined significance (MGUS) and ‘smouldering’ MM precede symptomatic MM. Cytogenetics in MM is the most powerful prognostication tool incorporated into different classifications, including the Revised International Staging System (R-ISS) and the Mayo Clinic Risk Stratification for Multiple Myeloma (mSMART). Methods commonly used to test for cytogenetic aberrations include conventional karyotyping and fluorescence in situ hybridisation (FISH), although the difficulty of obtaining metaphases in plasma cells results in low yields. Therefore, new genomic tools are essential to explore the complex landscape of genetic alterations in MM. These include next generation sequencing, a highly sensitive method to monitor minimal residual disease. The serial evolution of MGUS to MM is accompanied by a range of heterogenous genetic abnormalities, divided into primary (involving mostly chromosome 14 translocations and trisomies) and secondary genetic aberration events (involving mostly 17p, 1p, 13q deletions, 1q gain, or MYC translocations). Based on the primary genetic aberration results, strong prognostic features of MM have been identified with distinct clinical characteristics. High risk aberrations include 17p deletion, t(4;14), t(14;16), t(14;20) and chromosome 1 abnormalities. The incorporation of novel drugs and maintenance strategies in conjunction with autologous stem cell transplantation partially overcome the adverse effect of some of these genetic aberrations. Nonetheless, survival remains worse in this group compared to standard risk patients. Clinical decisions regarding treatment should be based on the cytogenetic results. The establishment of individualised and mutation-targeted therapies are of the greatest importance in future studies
