Abstract
SARS-CoV-2 vaccination significantly reduces morbidity and mortality, but has less impact on viral transmission rates, thus aiding viral evolution, and the longevity of vaccine-induced immunity rapidly declines. Immune responses in respiratory tract mucosal tissues are crucial for early control of infection, and can generate long-term antigen-specific protection with prompt recall responses. However, currently approved SARS-CoV-2 vaccines are not amenable to adequate respiratory mucosal delivery, particularly in the upper airways, which could account for the high vaccine breakthrough infection rates and limited duration of vaccine-mediated protection. In view of these drawbacks, we outline a strategy that has the potential to enhance both the efficacy and durability of existing SARS-CoV-2 vaccines, by inducing robust memory responses in the upper respiratory tract (URT) mucosa.

Abstract
Multiple myeloma (MM) is an incurable but treatment-sensitive cancer. For most patients, this means treatment with multiple lines of anti-myeloma therapy and a life with disease- and treatment-related symptoms and complications. Health-related quality of life (HRQoL) issues play an important role in treatment decision-making. Methodological challenges in longitudinal HRQoL measurements and analyses have been identified, including non-responses (NR) to scheduled questionnaires. Publications were identified for inclusion in a systematic review of longitudinal HRQoL studies in MM, focussing on methodological aspects of HRQoL measurement and analysis. Diversity in timing of HRQoL data collection and applied statistical methods were noted. We observed a high rate of NR, but the impact of NR was investigated in only 8/23 studies. Thus, evidence-based knowledge of HRQoL in patients with MM is compromised. To improve quality of HRQoL results and their implementation in daily practice, future studies should follow established guidelines.

Abstract
Maintenance (MT) may be prescribed after autologous stem cell transplant (ASCT) but there are often concerns about the impact on quality of life (QoL). QoL was compared between baseline patients (30-100 days post-ASCT and had not commenced MT); MT patients (>100 days post-ASCT and receiving MT), and no MT (>100 days post-ASCT and not receiving MT). Patients completed the EuroQoL five dimension (EQ-5D), the European Organization for Research and Treatment of Cancer QoL Questionnaire Core 30 (EORTC QLQ-C30), and the QoL Questionnaire Myeloma 20 module (QLQ-MY20). Differences between groups were explored with ordinary least squares regressions. Across US and Canada, 303 patients participated. Regression analyses found few differences between MT and no MT. Only diarrhea (EORTC-QLQ C30) and future perspectives (MY-20) domains differentiated; patients on MT scored worse for diarrhea (+9.43; p = .0358) and future perspectives (-11.39; p = .0196). Collectively, the results suggest that MT is not associated with a notable QoL detriment.

Abstract
OBJECTIVES Multiple myeloma (MM) patients report high symptom burden and reduced health-related quality of life (HRQoL) compared to patients with other haematological malignancies. The aim of this review was to analyse published longitudinal studies including MM patients according to a change in HRQoL scores, which is perceived as beneficial to the patient according to two published guidelines. METHODS A literature search was performed May 2016. Publications with longitudinal follow-up using the EORTC QLQ-C30 instrument for HRQoL measurement of physical functioning, global quality of life, fatigue and/or pain were included. An analysis of mean change from baseline was carried out according to minimal important difference (MID). RESULTS Large and medium HRQoL improvements were reported during first-line treatments. No clinically beneficial change or deteriorations in scores of global QoL or fatigue were reported during relapse treatment. HRQoL data during maintenance therapy are sparse and inconclusive. CONCLUSIONS Guidelines for interpreting changes in HRQoL including definitions of MID have been developed; however, consensus is missing. Improvements in HRQoL are far more likely to occur during first-line compared to relapsed treatment regimens. The background of these findings should be in focus in future studies, and HRQoL measurements should be integrated in maintenance studies.

Abstract
INTRODUCTION Treatment advances in multiple myeloma have increased expected survival from months to years for some patients. Alongside improved survival emerges a need to better understand and measure health-related quality of life (HRQOL), both in research and clinical settings. OBJECTIVES (i) Identify HRQOL tools validated for use in myeloma; (ii) identify issues important to HRQOL from the point of view of patients with myeloma; (iii) describe the measurement properties of each HRQOL tool; (iv) evaluate the content validity of HRQOL tools in terms of their ability to capture all issues important to patients and (v) explore the suitability of each HRQOL tool for use in different settings. METHOD Systematic literature review of six databases with no limits by date or language. RESULTS Thirty-nine studies reported validation of 13 HRQOL instruments. Seven studies identified issues important to HRQOL from the patients' perspective. No instrument was comprehensive to all issues important to patients. The EORTC-QLQ-C30 and MY24 have undergone the most comprehensive psychometric validation. Most validation occurred in trial patients and not clinically representative groups. No studies evaluated clinical utility of tools alongside routine practice. CONCLUSION The best existing HRQOL tools are designed predominantly for use in research. Reliable, valid and responsive tools exist for this purpose, but may miss issues important to patients. The design of HRQOL measures should be guided by intended utility, whether for research or clinical practice, and further validation of HRQOL tools in clinically representative groups is needed. Development and validation of HRQOL tools for clinical use may be of value.

Abstract
OBJECTIVES The aim of this study was to assess the psychometric properties of the Greek EORTC QLQ-C30 and QLQ-MY20 instruments. METHOD A sample of myeloma patients (N = 89) from two tertiary hospitals were surveyed with the QLQ-C30, QLQ-MY20 and various demographic and disease related questions. The previously validated Greek SF-36 instrument was used as a "gold standard" for health-related quality of life (HRQoL) comparisons. Hypothesized scale structure, internal consistency reliability (Cronbach's alpha) and various forms of construct validity (convergent, discriminative, concurrent and known-groups) were assessed. RESULTS Multitrait scaling confirmed scale structure of the QLQ-C30 and QLQ-MY20, with good item convergence (96% and 72%) and discrimination (78% and 58%) rates. Cronbach's α was >0.70 for all but one scale (cognitive functioning). Spearman's correlations between similar QLQ-C30 and SF-36 scales ranged between 0.35-0.80 (P < 0.001). Expected interscale correlations and known-groups comparisons supported construct validity. QLQ-MY20 scales showed comparatively lower correlations with QLQ-C30 functional scales, and higher correlations with conceptually related symptom scales. CONCLUSIONS The observed psychometric properties of the two instruments imply suitability for assessing myeloma HRQoL in Greece. Future studies should focus on generalizability of the results, as well as on specific issues such as longitudinal validity and responsiveness.

Abstract
BACKGROUND This prospective population-based study describes health-related quality of life (HRQOL) and disease-specific complaints of patients with multiple myeloma (MM) up to 10 yr post-diagnosis. METHODS The Eindhoven Cancer Registry was used to select all patients diagnosed with MM from 1999 to 2010. Patients with MM completed the EORTC QLQ-C30 and EORTC QLQ-MY20 questionnaires at baseline (n = 156; 74% response rate) and 1 yr later (n = 80). The EORTC QLQ-C30 was also completed by an age- and sex-matched normative population (n = 500). RESULTS Patients with MM reported statistically significant and clinically relevant worse scores on all EORTC QLQ-C30 scales (all P's at least < 0.01) compared to the norm. Also, patients with MM reported a mean decrease (e.g., worsening) between baseline and 1-yr follow-up scores for: quality of life (mean, 68 vs. 55, respectively, P < 0.001; 74% of patients had a deteriorated score), fatigue (33 vs. 39, P < 0.05; 50%), nausea and vomiting (6.3 vs. 13, P < 0.05; 71%), pain (33 vs. 43, P < 0.05; 59%), and dyspnea (17 vs. 33, P < 0.001; 66%). The most bothering symptoms during the past week were tingling hands/feet (32%), back pain (28%), bone aches/pain (26%), pain in arm/shoulder (19%), and feeling drowsy (18%). Also, 37% worried about their future health, 34% thought about their disease, and 21% worried about dying. CONCLUSION Patients with MM experience a very high symptom burden and low HRQOL. Future studies should focus on possible mechanisms that can predict low HRQOL and high symptom burden in patients with MM and should investigate optimal ways to alleviate these.

Abstract
Interferon alpha (IFN-α) has been used as a maintenance therapy after autologous stem cell transplantation (ASCT) for multiple myeloma (MM) patients. In this study, we combined GM-CSF with IFN-α in order to improve IFN tolerance in post-ASCT myeloma patients. Primary aims were to evaluate myelotoxicity and effectiveness of this maintenance therapy. The treatment included 4 × 106 units of IFN-α and 125 μg/m2 of GM-CSF given three times a week for twelve months. Twenty seven patients were enrolled within 120 days after ASCT. One patient discontinued treatment due to thrombocytopenia and seven others were taken off study due to flu-like symptoms and/or increase in liver enzymes. With a median follow-up of 45.5 months, the median overall survival was not reached while the median progression-free survival was 28 months. Eleven patients (42%) have remained in very good partial remission or complete remission since ASCT. In conclusion, our results demonstrate that maintenance with GM-CSF and IFN-α is safe and effective.

Abstract
The activity of several potent adjuvants, including incomplete Freund's adjuvant, CpG oligodeoxynucleotides, and alum, has been shown to be due at least in part to the induction of cytokines, including type I interferons (IFNs), IFN-gamma, interleukin-2 (IL-2), and IL-12, that play key roles in the regulation of innate and adaptive immunity. The relatively short half-life of recombinant homologues of cytokines has limited their use as vaccine adjuvants. These difficulties have been overcome by encapsulation into liposomes and the use of cytokine expression vectors co-administered with DNA vaccines. Although a number of cytokines including IFN-alpha, IFN-gamma, IL-2, IL-12, IL-15, IL-18, IL-21, GM-CSF, and Flt-3 ligand have been shown to potentiate the immune response to vaccination in various experimental models, the full potential of cytokines as vaccine adjuvants remains to be established.

Abstract
BACKGROUND Maintenance therapy with interferon-alpha after high-dose treatment with stem cell support in multiple myeloma has been intensively debated. In this study, we evaluated the response to treatment with interferon-alpha in relation to genetic variation in genes related to inflammation. DESIGN AND METHODS In a retrospective study of 296 patients with multiple myeloma undergoing high-dose therapy between 1994 and 2004, 146 patients were treated with interferon-alpha as maintenance therapy. We tested the polymorphisms IL1B T-31C, IL6 G-174C, NFKB1-94ins/delATTG, CD3EAP G-21A and PPP1R13L IVS1 A4364G for associations with time to treatment failure and overall survival with and without interferon-alpha treatment. RESULTS The wild type ins-allele of polymorphism NFKB1-94 ins/delATTG was, by multivariate Cox analysis, associated with longer time to treatment failure (p=0.01) and overall survival (p=0.0084) when tested between treatment arms and in the subgroup of patients treated with interferon-alpha the wild type ins-allele was associated with longer overall survival (p=0.002). In the absence of interferon-alpha treatment, there was no association between the polymorphisms and treatment outcome, except for patients homozygous for the wild type G allele of IL6 G-174C who survived longer (p= 0.0074) than variant allele carriers. There was no association between the polymorphisms IL1B T-31C, CD3EAP G-21A and PPP1R13L IVS1 A4364G and treatment outcome for interferon-alpha. CONCLUSIONS Patients who are homozygous carriers of the wild type ins-allele of the NFKB1 -94ins/delATTG polymorphism may benefit from treatment with interferon-alpha, in contrast to patients carrying the variant allele. This result may indicate that the effect of interferon-alpha treatment is dependent on the availability of nuclear factor-kappaB and the polymorphism in NFKB1 may, therefore, be a good prognostic marker for multiple myeloma patients on maintenance treatment with interferon-alpha after high-dose therapy. A prospective study of interferon-alpha treatment in relation to NFKB1 -94ins/delATTG is highly warranted.

Abstract
OBJECTIVES Patients with multiple myeloma (MM) often have pronounced symptoms and substantially reduced quality of life. The aims of treatment are to control disease, maximise quality of life and prolong survival. Hence, health-related quality of life (HRQOL) should be an important end-point in randomised controlled trials (RCTs) in addition to traditional endpoints. We wanted to evaluate whether trials reporting HRQOL outcomes have influenced clinical decision making and whether HRQOL was assessed robustly according to predefined criteria. METHODS A systematic review identified RCTs in MM with HRQOL assessment as a study end-point. The methodological quality of these studies was assessed according to a checklist developed for evaluating HRQOL outcomes in clinical trials. The impact of the HRQOL results on clinical decision making was assessed, using published clinical guidelines as a reference. RESULTS Fifteen publications presenting RCTs with HRQOL as a study end-point were identified. In 13 trials, the author stated that HRQOL results should influence clinical decision making. We found, however, that the HRQOL data only had a limited impact on published treatment guidelines for bisphosphonates, high-dose treatment, interferon, erythropoiesis-stimulating agents and novel agents. CONCLUSION The present review indicates that the there are still few RCTs in MM including HRQOL as a study end-point. Systematic incorporation of HRQOL measures into clinical trials allows for a comparison of treatment arms that includes the patients' perspective. Before the full impact on clinical decisions can be realised, the quality and methodology of collecting HRQOL data must be further improved and the results rendered more comprehensible to clinicians.

Abstract
Type I interferons (IFNs) produced primarily by plasmacytoid dendritic cells (pDCs) as part of the innate immune response to infectious agents induce the maturation of myeloid DCs and enhance antigen presentation. Type I IFNs also enhance apoptosis of virus-infected cells, stimulate cross priming and enhanced presentation of viral peptides. Type I IFNs are powerful polyclonal B-cell activators that induce a strong primary humoral immune response characterized by isotype switching and protection against virus challenge. Type I IFNs stimulate an IgG2a antibody response characteristic of Th1 immunity when ad-mixed with influenza virus vaccine and injected intramuscurarly (i.m.) or administered intranasally. The adjuvant activity of type I IFNs has been shown to involve direct effects of IFN on B-cells, effects on T-cells, as well as effects on antigen presentation. Oromucosal administration of type I IFNs concomitantly with i.m. injection of vaccine alone can also enhance the antibody response to influenza vaccination by enhancing trafficking of antigen-presenting cells towards the site of vaccination. Recombinant IFNs are potent adjuvants that may find application in both parenterally and mucosally administered vaccines.

Abstract
OBJECTIVE Most myeloma tumor cells from patients express NKG2D ligands. We have reported the development of a chimeric NKG2D receptor (chNKG2D), which consists of the NKG2D receptor fused to the CD3zeta chain. T cells expressing this receptor kill and produce cytokines in response to NKG2D-ligand+ tumor cells. Therefore, we investigated whether human chNKG2D T cells respond against human myeloma cells. MATERIALS AND METHODS ChNKG2D T cells were generated from healthy donors and myeloma patients. The effector phase of chNKG2D T cells was analyzed by cell-surface marker expression and human myeloma cell lines were tested for expression of NKG2D ligands. Lysis of myeloma cell lines and cytokine secretion by chNKG2D T cells was determined. ChNKG2D T cells grown in serum-free media, or cyropreserved, were assessed for effector cell functions. RESULTS Myeloma cell lines expressed NKG2D ligands. ChNKG2D T cells from healthy donors and myeloma patients lysed myeloma cells, and secreted proinflammatory cytokines when cultured with myeloma cells or patient bone marrow, but not with peripheral blood mononuclear cells or normal bone marrow. Lysis of myeloma cells was dependent on chNKG2D T-cell expression of NKG2D and perforin. Additionally, chNKG2D T cells upregulated CD45RO, did not express CD57, and maintained expression of CD27, CD62L, and CCR7, indicating that the T cells were at an early effector stage. Finally, we showed that chNKG2D T cells generated with serum-free media, or when cryopreserved, maintained effector functions. CONCLUSION ChNKG2D T cells respond to human myeloma cells and can be generated using clinically applicable cell culture techniques.

Abstract
Treatment for patients with myeloma has changed unrecognisably over the last two decades and now includes a sequence of treatments including chemotherapy, biological targeted therapy with or without consideration for high-dose therapy (autologous and allogeneic stem cell transplantation for younger and fit patients). As patients can now expect a doubling of median survival and a 20-30% chance of surviving longer than 10 years, the focus of treatment is shifting to long-term quality of life. This article focuses on future challenges facing clinicians treating myeloma and how best we may optimize our resources.

Abstract
In the constantly evolving field of myeloma, this special issue is slanted towards how the newer targeted treatments fit in with various transplantation strategies. High-dose treatment for myeloma with autologous stem cell transplantation started 25 years ago, with the consequence of producing complete remissions and a doubling of survival. Since then, its role has been refined and it has been accepted as standard treatment. The current challenge is to optimize its use into a background of the development, availability and regulatory approval of newer targeted therapies such as Thalidomide, Revlimid (Lenalidomide) and Velcade (Bortezomib). This special issue addresses these problems, and gives particular emphasis on the attainment of very long-term survival, with normal quality of life for patients with myeloma who do not necessarily need to be cured of their molecular disease, that is, they are 'operationally cured.' It is hoped that the reader will find the information in this issue useful in the day-to-day management of patients and we hope that this will also inspire new research directions designed to improve the outcome of patients with myeloma.
