A Population-Based Family Case-Control Study of Sun Exposure and Follicular Lymphoma Risk.

BACKGROUND: Epidemiologic evidence suggests an inverse association between sun exposure and follicular lymphoma risk. METHODS: We conducted an Australian population-based family case-control study based on 666 cases and 459 controls (288 related, 171 unrelated). Participants completed a lifetime residence and work calendar and recalled outdoor hours on weekdays, weekends, and holidays in the warmer and cooler months at ages 10, 20, 30, and 40 years, and clothing types worn in the warmer months. We used a group-based trajectory modeling approach to identify outdoor hour trajectories over time and examined associations with follicular lymphoma risk using logistic regression. RESULTS: We observed an inverse association between follicular lymphoma risk and several measures of high lifetime sun exposure, particularly intermittent exposure (weekends, holidays). Associations included reduced risk with increasing time outdoors on holidays in the warmer months [highest category OR = 0.56; 95% confidence interval (CI), 0.42-0.76; Ptrend < 0.01], high outdoor hours on weekends in the warmer months (highest category OR = 0.71; 95% CI, 0.52-0.96), and increasing time outdoors in the warmer and cooler months combined (highest category OR = 0.66; 95% CI, 0.50-0.91; Ptrend 0.01). Risk was reduced for high outdoor hour maintainers in the warmer months across the decade years (OR = 0.71; 95% CI, 0.53-0.96). CONCLUSIONS: High total and intermittent sun exposure, particularly in the warmer months, may be protective against the development of follicular lymphoma. IMPACT: Although sun exposure is not recommended as a cancer control policy, confirming this association may provide insights regarding the future control of this intractable malignancy.

The influence of immunodeficiency, disease features, and patient characteristics on survival in plasmablastic lymphoma.

ABSTRACT: Plasmablastic lymphoma (PBL) is a rare and aggressive non-Hodgkin lymphoma associated with immunodeficiency, characterized by uncertain treatment approaches and an unfavorable prognosis. We conducted a multicenter, international, retrospective cohort study, aiming to characterize the clinical features, risk factors, and outcomes of patients with PBL. Data were collected from 22 institutions across 4 countries regarding patients diagnosed with PBL between 1 January 1999 and 31 December 2020. Survival risk factors were analyzed using both univariate and multivariate regression models. Overall survival (OS) was calculated using Kaplan-Meier statistics. First-line treatment regimens were stratified into standard- and higher-intensity regimens, and based on whether they incorporated a proteasome inhibitor (PI). A total of 281 patients (median age, 55 years) were included. Immunodeficiency of any kind was identified in 144 patients (51%), and 99 patients (35%) had HIV-positive results. The 5-year OS for the entire cohort was 36% (95% confidence interval, 30%-42%). In multivariate analysis, inferior OS was associated with Epstein-Barr virus-negative lymphoma, poor performance status, advanced stage, and bone marrow involvement. In an independent univariate analysis, the international prognostic index was associated with OS outcomes. Neither immunosuppression nor HIV infection, specifically, influenced OS. Among patients treated with curative intent (n = 234), the overall response rate was 72%. Neither the intensity of the treatment regimen nor the inclusion of PIs in first-line therapy was associated with OS. In this large retrospective study of patients with PBL, we identified novel risk factors for survival. PBL remains a challenging disease with poor long-term outcomes.

Occupational exposure to extremely low-frequency magnetic fields and follicular lymphoma risk: a family case-control study.

OBJECTIVES: We aimed to examine the relationship between occupational exposure to extremely low-frequency magnetic fields (ELF-MFs) and follicular lymphoma (FL) risk. METHODS: We conducted a family case-control study between 2011 and 2016 in Australia and included 681 cases. Controls were either a family member of cases (related (n=294), unrelated (n=179)) or were unrelated recruited for a similarly designed Australian multiple myeloma study (n=711). We obtained detailed job histories using lifetime work calendars. We assigned exposure to ELF-MFs using an enhanced job exposure matrix, with a lag period of 10 years. We examined associations with FL risk using logistic regression accounting for relatedness between cases and controls. We performed sensitivity analyses including by control type, by sex, complete case analyses, ELF-MF exposure percentiles in addition to quartiles, ELF-MF exposure in the maximum exposed job, a shorter lag period (1 year) and the cumulative exposure in the most recent time period (1-9 years). RESULTS: We observed no association with the average intensity, duration or lifetime cumulative exposure to occupational ELF-MF exposure in the primary or sensitivity analyses. CONCLUSIONS: Our findings do not support an association between occupational ELF-MF exposure and FL risk. Although the inclusion of family members as part of the larger control group may have biased our risk estimates towards the null, findings were similar in sensitivity analyses restricted to cases and unrelated controls. Further research incorporating enhanced exposure assessment to ELF-MF is warranted to inform occupational safety regulations and any potential role in lymphomagenesis.

Factors determining whether diffuse large B-cell lymphoma samples are detected by flow cytometry.

INTRODUCTION: Flow cytometry (FCM) is widely used in the diagnosis of mature B-cell neoplasms (MBN), and FCM data are usually consistent with morphological findings. However, diffuse large B-cell lymphoma (DLBCL), a common MBN, is sometimes not detected by FCM. This study aimed to explore factors that increase the likelihood of failure to detect DLBCL by FCM. METHODS: Cases with a final diagnosis of DLBCL that were analysed by eight-colour FCM were retrospectively collated. Clinical, FCM, histopathological and genetic data were compared between cases detected and cases not detected by FCM. RESULTS: DLBCL cases from 135 different patients were analysed, of which 22 (16%) were not detected by FCM. In samples not detected by flow cytometry, lymphocytes were a lower percentage of total events (p = 0.02), and T cells were a higher percentage of total lymphocytes (p = 0.01). Cases with high MYC protein expression on immunohistochemistry were less likely to be missed by FCM (p = 0.011). Detection of DLBCL was not different between germinal centre B-cell (GCB) and non-GCB subtypes, not significantly affected by the presence of necrosis or fibrosis, and not significantly different between biopsy specimens compared to fine-needle aspirates, or between samples from nodal compared to extranodal tissue. CONCLUSION: The study identifies several factors which affect the likelihood of DLBCL being missed by FCM. Even with eight-colour analysis, FCM fails to detect numerous cases of DLBCL.

Rates of Menstrual History-Taking and Counseling With Anticancer Treatments Are Low: People Who Menstruate Deserve Gender-Specific Cancer Care.

BACKGROUND: Chemotherapy predisposes people who menstruate to abnormal uterine bleeding that can be life-threatening and may also damage ovaries, resulting in premature menopause. The purpose of this study was to explore the incidence of menstrual history documentation and counseling before, during, and after cancer treatment. PATIENTS AND METHODS: The medical charts of 137 consecutive females (self-reported) aged 18 to 49 years receiving anticancer treatment at a major tertiary metropolitan hospital in Australia between 2017 and 2020 were reviewed. Data collected included primary diagnosis, stage of cancer, treatment(s) received, rates of remission or progression, documentation of involvement of a specialist gynecologist, reproductive history, menstrual disturbances, menstruation counseling or intervention offered, and diagnosis of early ovarian failure. RESULTS: Only 16.1% of patients had their menstrual history documented at the initial consult, and 49.6% had their menstrual history documented at a subsequent consult with their treating oncologist or hematologist. Most (82.4%) patients with a menstrual history documented experienced menstrual disturbance posttreatment, most commonly amenorrhea (48.0%), followed by menopause or menopause symptoms (20.6%), irregular menstrual bleeding (16.7%), menorrhagia (13.7%), dysmenorrhea (3.9%), and iron deficiency from bleeding (2.9%). Menopause/Menopausal symptoms and iron deficiency were more likely to be treated than other disturbances. CONCLUSIONS: Menstruation disturbance is a common side effect of cancer treatment. Menstrual care should be integral to cancer care for people who menstruate, and higher engagement could be achieved through education of medical and allied health staff, information technology systems automating prompts and referral pathways, regular audits to ensure compliance, better alliances between cancer and fertility specialists, and the creation of accessible patient information to promote awareness and facilitate discussion.

Associations between early-life growth pattern and body size and follicular lymphoma risk and survival: a family-based case-control study.

BACKGROUND: The influence of early-life growth pattern and body size on follicular lymphoma (FL) risk and survival is unclear. In this study, we aimed to investigate the association between gestational age, growth during childhood, body size, changes in body shape over time, and FL risk and survival. METHODS: We conducted a population-based family case-control study and included 706 cases and 490 controls. We ascertained gestational age, growth during childhood, body size and body shape using questionnaires and followed-up cases (median=83 months) using record linkage with national death records. We used a group-based trajectory modeling approach to identify body shape trajectories from ages 5-70. We examined associations with FL risk using unconditional logistic regression and used Cox regression to assess the association between body mass index (BMI) and all-cause and FL-specific mortality among cases. RESULTS: We found no association between gestational age, childhood height and FL risk. We observed a modest increase in FL risk with being obese 5 years prior to enrolment (OR=1.43, 95 %CI=0.99-2.06; BMI ≥30 kg/m2) and per 5-kg/m2 increase in BMI 5 years prior to enrolment (OR=1.14, 95 %CI=0.99-1.31). The excess risk for obesity 5 years prior to enrolment was higher for ever-smokers (OR=2.00, 95 %CI=1.08-3.69) than never-smokers (OR=1.14, 95 %CI=0.71-1.84). We found no association between FL risk and BMI at enrolment, BMI for heaviest lifetime weight, the highest categories of adult weight or height, trouser size, body shape at different ages or body shape trajectory. We also observed no association between all-cause or FL-specific mortality and excess adiposity at or prior to enrolment. CONCLUSION: We observed a weak association between elevated BMI and FL risk, and no association with all-cause or FL-specific mortality, consistent with previous studies. Future studies incorporating biomarkers are needed to elucidate possible mechanisms underlying the role of body composition in FL etiology.

Associations between Smoking and Alcohol and Follicular Lymphoma Incidence and Survival: A Family-Based Case-Control Study in Australia.

The association between smoking and alcohol consumption and follicular lymphoma (FL) incidence and clinical outcome is uncertain. We conducted a population-based family case-control study (709 cases: 490 controls) in Australia. We assessed lifetime history of smoking and recent alcohol consumption and followed-up cases (median = 83 months). We examined associations with FL risk using unconditional logistic regression and with all-cause and FL-specific mortality of cases using Cox regression. FL risk was associated with ever smoking (OR = 1.38, 95%CI = 1.08−1.74), former smoking (OR = 1.36, 95%CI = 1.05−1.77), smoking initiation before age 17 (OR = 1.47, 95%CI = 1.06−2.05), the highest categories of cigarettes smoked per day (OR = 1.44, 95%CI = 1.04−2.01), smoking duration (OR = 1.53, 95%CI = 1.07−2.18) and pack-years (OR = 1.56, 95%CI = 1.10−2.22). For never smokers, FL risk increased for those exposed indoors to >2 smokers during childhood (OR = 1.84, 95%CI = 1.11−3.04). For cases, current smoking and the highest categories of smoking duration and lifetime cigarette exposure were associated with elevated all-cause mortality. The hazard ratio for current smoking and FL-specific mortality was 2.97 (95%CI = 0.91−9.72). We found no association between recent alcohol consumption and FL risk, all-cause or FL-specific mortality. Our study showed consistent evidence of an association between smoking and increased FL risk and possibly also FL-specific mortality. Strengthening anti-smoking policies and interventions may reduce the population burden of FL.

Effect of donor age on adult unrelated donor haemopoietic cell transplant outcome: the Australian experience.

BACKGROUND: Results have been varied regarding the effect of donor age on the outcome of unrelated donor haemopoietic cell transplantation (HCT). AIMS: To determine the influence of donor age on adult unrelated donor HCT outcome in Australia. METHODS: Patients were included in the study if they were aged 16 years or above and underwent first allogeneic unrelated donor HCT in Australia for the indications of acute lymphoblastic leukaemia (ALL), acute myelogenous leukaemia (AML), chronic myelogenous leukaemia (CML) or myelodysplastic syndromes (MDS) between the years of 2001 and 2014 inclusive. The main outcome measure was overall survival (OS), which was tested against independent variables using univariate Kaplan-Meier methods and multivariate Cox regression. RESULTS: A total of 1158 unrelated donor HCT were represented in the data. Cumulative incidences of engraftment, transplant related mortality (TRM), acute graft-versus-host disease (GvHD), chronic GvHD and relapse were not significantly affected by donor age. OS probability at 5 years post-transplant was 48.3%. In multivariate analysis of OS, year of transplant 2001-2007, recipient age 40 years or greater, poor risk disease, human leukocyte antigen (HLA) match less than 6/6 and poor performance status at transplant (Karnofsky scale) were independently significant adverse OS risk factors. Donor age was not a significant risk factor for OS in univariate or multivariate analysis. CONCLUSIONS: The conclusion from this study was that donor age (up to 59 years) did not influence post-transplant outcome among adult unrelated donor HCT performed in Australia for haematologic malignancies.

Dietary intake of animal-based products and likelihood of follicular lymphoma and survival: A population-based family case-control study.

Background: The association between dietary intake of foods of animal origin and follicular lymphoma (FL) risk and survival is uncertain. In this study, we examined the relationship between dietary intake of dairy foods and fats, meat, fish and seafoods, and the likelihood of FL and survival. Methods: We conducted a population-based family case-control study in Australia between 2011 and 2016 and included 710 cases, 303 siblings and 186 spouse/partner controls. We assessed dietary intake of animal products prior to diagnosis (the year before last) using a structured food frequency questionnaire and followed-up cases over a median of 6.9 years using record linkage to national death data. We examined associations with the likelihood of FL using logistic regression and used Cox regression to assess association with all-cause and FL-specific mortality among cases. Results: We observed an increased likelihood of FL with increasing daily quantity of oily fish consumption in the year before last (highest category OR = 1.96, CI = 1.02-3.77; p-trend 0.06) among cases and sibling controls, but no associations with spouse/partner controls. We found no association between the likelihood of FL and the consumption of other types of fish or seafood, meats or dairy foods and fats. In FL cases, we found no association between meat or oily fish intake and all-cause or FL-specific mortality. Conclusion: Our study showed suggestive evidence of a positive association between oily fish intake and the likelihood of FL, but findings varied by control type. Further investigation of the potential role of environmental contaminants in oily fish on FL etiology is warranted.

Australia and New Zealand Transplant and Cellular Therapies COVID-19 vaccination consensus position statement.

Australia and New Zealand have achieved excellent community control of COVID-19 infection. In light of the imminent COVID-19 vaccination roll out in both countries, representatives of all adult and paediatric allogeneic bone marrow transplant and cellular therapy (TCT) centres as well as representatives from autologous transplant only centres in Australia and New Zealand collaborated with infectious diseases specialists with expertise in TCT on this consensus position statement regarding COVID-19 vaccination in TCT patients in Australia and New Zealand. It is our recommendation that TCT patients, should have expedited access to high-efficacy COVID-19 vaccines given that these patients are at high risk of morbidity and mortality from COVID-19 infection. We also recommend prioritising vaccination of TCT healthcare workers and household members of TCT patients. Vaccination should not replace other public health measures in TCT patients given the effectiveness of COVID-19 vaccination in TCT patients is unknown. Furthermore, given the limited available data, prospective collection of safety and efficacy data of COVID-19 vaccination in this patient group is a priority.

Pregnancy post autologous stem cell transplant with BEAM conditioning for multiple sclerosis.

BACKGROUND: Given the increasing numbers of multiple sclerosis (MS) patients undergoing autologous haematopoietic stem cell transplant (AHSCT) worldwide, and with women of childbearing age overrepresented in the target population, it is increasingly important to review fertility and pregnancy outcomes following AHSCT. OBJECTIVE: To evaluate the rate of pregnancy and complications post-AHSCT for MS. METHOD: Retrospective evaluation of the rate of pregnancy and associated complications in a cohort of patients post-AHSCT with BEAM conditioning for MS since 2010 in a tertiary referral centre. RESULTS: In our ongoing Phase 2 trial of AHSCT for MS, 55 patients have undergone AHSCT with 30 females being of childbearing age at time of transplantation. Four pregnancies occurred following AHSCT. Two pregnancies were carried to term. No maternal or neonatal complications were reported in either case. Two pregnancies were not carried to term due to elective terminations. Both of these patients became pregnant unexpectedly 2 years following AHSCT. Of the 21 male patients, one patient has fathered three children since his AHSCT. There were no newborn complications. CONCLUSIONS: This is the first report to our knowledge on fertility outcomes in both sexes post-AHSCT for MS. Patients of both sexes should be counselled prior to treatment on infertility and contraceptive use.

Altered Immune Reconstitution in Allogeneic Stem Cell Transplant Recipients With Human Immunodeficiency Virus (HIV).

BACKGROUND: Persons living with human immunodeficiency virus (HIV) are at elevated risk of developing the malignant diseases that require allogeneic stem cell transplantation (ASCT). Recent data suggest that these individuals are also at an elevated risk of certain complications post-ASCT. This risk may result from preexisting HIV-related factors affecting dynamics of immune reconstitution post-ASCT. However, to date, there has been little work describing the dynamics of immune reconstitution post-ASCT in persons with HIV and none comparing these data to controls without HIV. METHODS: We assessed T-cell reconstitution in 6 ASCT with HIV recipients (HIV+ASCT) compared to a control population of 21 ASCT without HIV recipients. In a subset of HIV+ASCT recipients we performed additional flow cytometry profiling of CD8+ T-cell subsets and antigen specificity of reconstituting CD4+ and CD8+ T cells. RESULTS: We observe no difference in post-ASCT CD4+ T cells between HIV+ASCT and HIV-negative ASCT recipients, despite much lower pre-ASCT CD4+ T-cell counts in the HIV+ASCT group. In contrast, we observed significantly higher CD8+ T-cell numbers in the HIV+ASCT group post-ASCT. The reconstituting CD8+ T-cells were predominantly CD45RO+, whereas homing markers and antigen specificity of these cells varied between participants. CONCLUSION: This study represents the most extensive characterization of immune-reconstitution post-ASCT in persons with HIV, and the first to our knowledge to compare these data to ASCT controls without HIV. The results indicate that immune reconstitution in this group can be affected by preexisting HIV infection and post-ASCT antigen exposure.

Australasian Trends in Allogeneic Stem Cell Transplantation for Myelofibrosis in the Molecular Era: A Retrospective Analysis from the Australasian Bone Marrow Transplant Recipient Registry.

To review the updated trends of national practice and outcomes in transplantation to treat myelofibrosis (MF), we retrospectively evaluated 142 patients who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) for primary (n = 94) or secondary (n = 48) MF at an Australian/New Zealand transplantation center between 2006 and 2017. The median duration of follow-up was 51.8 months (range, 3.1 to 148 months). The median age at allo-HSCT was 56 years (range, 26 to 69 years). Fifty-two percent of the patients had HLA-identical sibling donors, and 45% had matched unrelated donors (UD). Conditioning regimens were predominantly reduced intensity (83%). Before transplantation, 16% of the patients had undergone splenectomy or splenic irradiation, and 38% (n = 54) received JAK inhibitor therapy. JAK2 mutation testing was performed in 66.9% of the patients, whereas other mutations (CALR, MPL, ASXL1, SRSF2, U2AF1Q57, EZH2, and IDH1/2) were rarely tested (1.4% to 8.4%). Only 4.2% of patients had next-generation sequencing mutation analysis. The median time to neutrophil engraftment was 19 days (range, 10 to 43 days), and the median time to platelet engraftment was 27 days (range, 13 to 230 days). The cumulative incidence of grade II-IV acute graft-versus-host disease (aGVHD) was 21.4% at 100 days, and that of extensive chronic GVHD (cGVHD) at 5 years was 18.1%. Overall survival (OS) was 67% at 1 year and 57% at 5 years. GVHD-free, relapse-free survival was 54% at 1 year and 42% at 5 years. The cumulative incidence of nonrelapse mortality (NRM) was 16% at 100 days and 25% at 1 year. In multivariate analysis, age ≥65 years and use of an UD were identified as significant unfavorable risk factors for OS and NRM. Use of an UD increased the incidence of aGVHD, whereas administration of antithymocyte globulin/alemtuzumab lowered the risk of both aGVHD and cGVHD. Pretransplantation splenectomy/splenic irradiation had a positive influence on time to engraftment. There have been no improvements in the outcomes of allo-HSCT for MF in Australasia over the last decade, with a low uptake of molecular genomic technology due to limited access to funding.

Unrelated Donor Transplant Recipients Given Thymoglobuline Have Superior GRFS When Compared to Matched Related Donor Recipients Undergoing Transplantation without ATG.

Recipients of allogeneic hematopoietic stem cell transplantation (HSCT) from unrelated donors (URDs) and mismatched related donors (MMRDs) typically have a higher incidence of acute and chronic graft-versus-host disease (GVHD) compared with matched related donors (MRDs). Anti-T-cell globulins (ATGs) are often used to reduce GVHD in these recipients. We report the outcomes of 211 adult peripheral blood stem cell transplant recipients with myeloid malignancies who received a standardized transplant protocol, in which ATG (Thymoglobuline 4.5 mg/kg) was administered to recipients of URD and MMRD (n = 147) but not MRD (n = 64) transplant. For all patients, incidence of acute GVHD grades 2 to 4 was 21.4%, and chronic GVHD was 35.0%. Two-year overall survival was 63.2% (95% confidence interval, 55.8% to 71.5%), relapse-free survival was 55.3% (47.4% to 64.6%), and GVHD-free, relapse-free survival (GRFS) was 30.7% (23.2% to 40.8%). There were no differences between recipients of MRDs and other donors in relapse, nonrelapse mortality, and overall and relapse-free survival. However, compared with MRD, recipients from URDs and MMRDs had reduced moderate to severe chronic GVHD (10.4% versus 30.1%, P= .002), less chronic GVHD requiring systemic therapy (19.4% versus 38.9%, P = .006), and superior 2-year GRFS (35.5% versus 20.0%, P = .003). In this retrospective review of nonrandomized transplant groups, outcomes of HSCT performed using an URD with ATG during conditioning were superior to transplant from an MRD without ATG. The addition of Thymoglobuline to conditioning in HSCT from MRD should be further examined in prospective trials.

Immunogenicity and safety of the adjuvanted recombinant zoster vaccine in adults with haematological malignancies: a phase 3, randomised, clinical trial and post-hoc efficacy analysis.

BACKGROUND: The adjuvanted recombinant zoster vaccine (Shingrix) can prevent herpes zoster in older adults and autologous haemopoietic stem cell transplant recipients. We evaluated the safety and immunogenicity of this vaccine in adults with haematological malignancies receiving immunosuppressive cancer treatments. METHODS: In this phase 3, randomised, observer-blind, placebo-controlled study, done at 77 centres worldwide, we randomly assigned (1:1) patients with haematological malignancies aged 18 years and older to receive two doses of the adjuvanted recombinant zoster vaccine or placebo 1-2 months apart during or after immunosuppressive cancer treatments, and stratified participants according to their underlying diseases. The co-primary objectives of the study were the evaluation of safety and reactogenicity of the adjuvanted recombinant zoster vaccine compared with placebo from the first vaccination up to 30 days after last vaccination in all participants; evaluation of the proportion of participants with a vaccine response in terms of anti-glycoprotein E humoral immune response to the adjuvanted recombinant zoster vaccine at month 2 in all participants, excluding those with non-Hodgkin B-cell lymphoma and chronic lymphocytic leukaemia; and evaluation of the anti-glycoprotein E humoral immune responses to the vaccine compared with placebo at month 2 in all participants, excluding those with non-Hodgkin B-cell lymphoma and chronic lymphocytic leukaemia. We assessed immunogenicity in the per-protocol cohort for immunogenicity and safety in the total vaccinated cohort. The study is registered with ClinicalTrials.gov, number NCT01767467, and with the EU Clinical Trials Register, number 2012-003438-18. FINDINGS: Between March 1, 2013, and Sept 10, 2015, we randomly assigned 286 participants to adjuvanted recombinant zoster vaccine and 283 to placebo. 283 in the vaccine group and 279 in the placebo group were vaccinated. At month 2, 119 (80·4%, 95% CI 73·1-86·5) of 148 participants had a humoral vaccine response to adjuvanted recombinant zoster vaccine, compared with one (0·8%, 0·0-4·2) of 130 participants in the placebo group, and the adjusted geometric mean anti-glycoprotein E antibody concentration was 23 132·9 mIU/mL (95% CI 16 642·8-32 153·9) in the vaccine group and 777·6 mIU/mL (702·8-860·3) in the placebo group (adjusted geometric mean ratio 29·75, 21·09-41·96; p<0·0001) in all patients, excluding those with non-Hodgkin B-cell lymphoma and chronic lymphocytic leukaemia. Humoral and cell-mediated immune responses persisted above baseline until month 13 in all strata and, as expected, vaccine was more reactogenic than placebo (within 7 days after vaccination pain was reported by 221 [79·5%] of 278 vaccine group participants and 45 [16·4%] of 274 placebo group participants; fatigue was reported by 162 [58·3%] of 278 vaccine group participants and 102 [37·2%] of 274 placebo group participants). Incidences of unsolicited or serious adverse events, potential immune-mediated diseases, disease-related events, and fatal serious adverse events were similar between the groups. INTERPRETATION: The immunocompromised adult population with haematological malignancies is at high risk for herpes zoster. The adjuvanted recombinant zoster vaccine, which is currently licensed in certain countries for adults aged 50 years and older, is likely to benefit this population.

Recombinant Zoster Vaccine Significantly Reduces the Impact on Quality of Life Caused by Herpes Zoster in Adult Autologous Hematopoietic Stem Cell Transplant Recipients: A Randomized Placebo-Controlled Trial (ZOE-HSCT).

Herpes zoster (HZ) can have a substantial impact on quality of life (QoL). The vaccine efficacy (VE) of a recombinant zoster vaccine (RZV) was 68.2% (95% confidence interval [CI], 55.6% to 77.5%) in a phase 3 study in adult autologous hematopoietic stem cell transplant (HSCT) recipients (NCT01610414). Herein, we report the impact of RZV on patients' QoL. Autologous HSCT recipients were randomized 1:1 to receive 2 doses of RZV or placebo, given 1 to 2 months apart. QoL was measured by the Short Form Survey-36 and Euro-QoL-5 Dimension at baseline, 1 month, and 1 year postdose 2 and during suspected HZ episodes with the Zoster Brief Pain Inventory (ZBPI). The RZV impact on ZBPI burden of illness and burden of interference scores was estimated. The 2 scores were calculated from the area under the curve (days 0 to 182) of the ZBPI worst pain and ZBPI activities of daily living scores, respectively, assuming a score of 0 for patients not having a confirmed HZ episode. The ZBPI maximum worst pain score was significantly lower in the RZV than placebo group (mean: 5.8 versus 7.1, P = .011). Consequently, the VE estimates for HZ burden of illness (82.5%; 95% CI, 73.6 to 91.4) and burden of interference (82.8%; 95% CI, 73.3 to 92.3) were higher than the HZ VE estimate (ie, 68.2%). RZV showed significantly better QoL scores than placebo 1 week following rash onset among patients with confirmed HZ. In addition to reducing the risk of HZ and its complications, RZV significantly reduced the impact of HZ on patients' QoL in those who developed breakthrough disease.

Autologous hematopoietic stem cell transplant for autoimmune diseases: evolution,evidence of efficacy, and real-world economics.

Despite an increase in the development of biological therapies for autoimmune disease (AID), a proportion of patients remain treatment refractory, resulting in long term morbidity and increased rates of mortality. Furthermore, maintenance biologic therapies are associated with treatment-related side effects, significant financial cost,and restricted access, which is of particular relevance in the developing world. Although it carries a significant 'front loaded' cost both financially and regarding adverse events, autologous hematopoietic stem cell transplantation (AHSCT) represents a potential single therapeutic intervention, which in the appropriate patient, condition, and transplant center, may offer sustained disease remission resulting in improved overall survival, disease relapse-free survival, improved quality of life, and decreased financial burden. Emerging Phase II and III trial and registry data, to which our center has been a significant contributor over the past two decades, are providing invaluable evidence as to which AIDs are most likely to receive a sustained benefit from AHSCT and which conditioning regimens are preferable. Similar to trends for the treatment of malignant disease, AHSCT for AID may find a place in both developed and developing countries as nations become more familiar with the transplantation process. If this occurs, benchmarking by key regulatory bodies, collaboration between medical specialties, and the development of experienced 'centers of excellence' will be key to enhance safety and benefit to patients and society at large.

Activity and Capacity Profile of Transplant Physicians and Centers in Australia and New Zealand.

We conducted a study to analyze and report on indicators of hematopoietic cell transplant (HCT) physician time use and HCT center output measures. HCT centers in Australia and New Zealand (A&NZ) were invited to provide demographic and time use details for physicians participating in HCT patient care (HCT physicians). Resource details for adult and pediatric centers were included. From a total of 46 centers that were invited to participate, completed data were received from 37 centers (80%) representing 185 HCT physicians, with a median age of 48 (range, 33 to 72), of whom 31% were women. Just over half of HCT physicians cited prior work experience in large overseas HCT centers (97, 52%) and over one-third (79, 43%) possessed postgraduate qualifications other than specialist training. Total annual mean HCTs per HCT physician full-time equivalent (FTE) were 14.2 for centers performing both allogeneic and autologous HCT, 6.6 for autologous only centers, and 10.6 for all centers. For all HCT physicians surveyed the mean proportion of time spent on HCT related tasks was 31.7%. In A&NZ, for centers that perform both allografts and autografts, there was a mean of 4.0 allogeneic HCT annually per HCT bed, compared with 2.6 for the United States and 7.1 allogeneic HCT annually per HCT physician FTE (United States, 6.3). Projections of the A&NZ HCT physician workforce indicated that the numbers of HCT physicians are likely to stay within the region of 170 to 190 for the next 10 years, whereas HCT activity will likely continue to climb steadily. Healthcare and government authorities should be prepared to enable and support greater HCT activity in A&NZ in the future.
