RESUMEN
BACKGROUND: Transition of care from hospitalisation to home is a complex process with potential patient safety risks, especially for patients with multimorbidity. Traditionally, the quality of transition of care has been evaluated primarily through readmission rates. However, interpreting the readmission rates presents challenges, and readmission rates fail to capture the patient's perspective on the quality of the care transition. Insight into the patient's experience with their care or a health service can be provided through the use of patient-reported experience measures (PREMs), and the two PREMs Care Transitions Measure 15 (CTM-15) and Partners at Care Transitions Measure part 1 and 2 (PACT-M1 and PACT-M2) assess on the quality of transition of care from the patients' perspective. The aim of this study was to translate, culturally adapt, and assess content validity of CTM-15, PACT-M1, and PACT-M2 for Danish-speaking patients with multimorbidity. METHODS: A two-step approach was used for content validation, involving cognitive debriefing and interviews with patients, representing the target group, as well as quantitative data collection from healthcare professionals representing all three sectors of the Danish healthcare system. The patients were systematically interviewed regarding the aspects of content validity; comprehensibility, relevance, and comprehensiveness. The healthcare professionals assessed the relevance and comprehensiveness of each item through questionnaires, allowing the calculation of a content validity index (CVI). An item CVI ≥ 0.78 is considered good. RESULTS: The results of the qualitative data indicated that both CTM-15 and the PACT-M questionnaires were considered relevant, and comprehensible, and comprehensive to the target group. The CVI computed at item level determined that PACT-M1 and PACT-M2 demonstrated excellent content validity among the healthcare professionals, whereas the CVI for two items of the CTM-15 fell below the threshold value for "good". CONCLUSION: The Danish versions of the PACT-M questionnaires demonstrated good content validity, and the CTM-15 demonstrated acceptable content validity based on qualitative data from patients and quantitative data from healthcare professionals. Further validation of the questionnaires, by assessing their construct validity and reliability is recommended.
In this study, we aimed to translate two questionnaires, CTM-15 and PACT-M, that address patients' perspectives on the quality of transition of care, into Danish. Furthermore, we assessed their content validity i.e., their relevance, comprehensibility, and comprehensiveness. The study is important because we need to include the patients' experiences in the overall evaluation of transition of care from hospital admission to home. This is possible through validated questionnaires. In order to investigate the content validity, it is important to include representatives of the target group, in this study patients with multimorbidity, as well as professional experts in the area. We interviewed patients about their perception of the relevance, comprehensibility, and comprehensiveness of the questionnaires. Additionally, we asked healthcare professionals about the relevance and comprehensiveness of the questionnaires. PACT-M demonstrated good content validity according to both patients and healthcare professionals. CTM-15 showed good content validity among patients, however, two items were not considered relevant by healthcare professionals. To ensure the usability of the questionnaires, further investigation into their construct validity, reliability, and responsiveness is necessary. Upon completion of the validation process, the questionnaires will be valuable tools in research projects aiming to improve the transition of care, as well as in quality monitoring and improvement initiatives.

PURPOSE: Non-response (NR) to patient-reported outcome (PRO) questionnaires may cause bias if not handled appropriately. Collecting reasons for NR is recommended, but how reasons for NR are related to missing data mechanisms remains unexplored. We aimed to explore this relationship for intermittent NRs. METHODS: Patients with multiple myeloma completed validated PRO questionnaires at enrolment and 12 follow-up time-points. NR was defined as non-completion of a follow-up assessment within seven days, which triggered contact with the patient, recording the reason for missingness and an invitation to complete the questionnaire (denoted "salvage response"). Mean differences between salvage and previous on-time scores were estimated for groups defined by reasons for NR using linear regression with clustered standard errors. Statistically significant mean differences larger than minimal important difference thresholds were interpreted as "missing not at random" (MNAR) mechanism (i.e. assumed to be related to declining health), and the remainder interpreted as aligned with "missing completely at random" (MCAR) mechanism (i.e. assumed unrelated to changes in health). RESULTS: Most (7228/7534 (96%)) follow-up questionnaires were completed; 11% (802/7534) were salvage responses. Mean salvage scores were compared to previous on-time scores by reason: those due to hospital admission, mental or physical reasons were worse in 10/22 PRO domains; those due to technical difficulties/procedural errors were no different in 21/22 PRO domains; and those due to overlooked/forgotten or other/unspecified reasons were no different in any domains. CONCLUSION: Intermittent NRs due to hospital admission, mental or physical reasons were aligned with MNAR mechanism for nearly half of PRO domains, while intermittent NRs due to technical difficulties/procedural errors or other/unspecified reasons generally were aligned with MCAR mechanism.
RESUMEN
BACKGROUND: Decisions regarding maintenance therapy in patients with multiple myeloma should be based on both treatment efficacy and health-related quality of life (HRQL) consequences. In the CARFI trial, patients with first relapse of multiple myeloma underwent salvage autologous stem cell transplantation (salvage ASCT) before randomization to carfilzomib-dexamethasone maintenance therapy (Kd) or observation. The primary clinical endpoint was time to progression, which was extended by 8 months by Kd. The aim of this paper is to present the all HRQL endpoints of the CARFI trial including the HRQL effect of Kd maintenance therapy relative to observation. The primary HRQL endpoint was assessed by EORTC QLQ-C30 Summary score (QLQ-C30-sum) at 8 months follow-up. A key secondary HRQL endpoint was quality-adjusted progression-free-survival (QAPFS). METHODS: HRQL was assessed with EORTC QLQ-C30, EORTC QLQ-MY20 and FACT/GOG-Ntx at randomization and every second month during follow-up. HRQL data were analyzed with linear mixed effect models until 8 months follow-up. QAPFS per individual was calculated by multiplying progression-free survival (PFS) by two quality-adjustment metrics, the QLQ-C30-sum and EORTC Quality of Life Utility Measure-Core 10 dimensions (QLU-C10D). The QAPFS per treatment group was estimated with the Kaplan-Meier method. P < 0.05 was used for statistical significance, and a between-group minimal important difference of 10 points was interpreted as clinically relevant for the QLQ-C30-sum. RESULTS: 168 patients were randomized. HRQL questionnaire compliance was 93%. For the QLQ-C30-sum, the difference of 4.62 points (95% confidence interval (CI) -8.9: -0.4, p = 0.032) was not clinically relevant. PFS was 19.3 months for the Kd maintenance group and 16.8 months for the observation group; difference = 2.5 months (95% CI 0.5; 4.5). QAPFS based on the QLQ-C30-sum for the Kd maintenance group was 18.0 months (95% CI 16.4; 19.6) and for the observation group 15.0 months (95% CI 13.5; 16.5); difference = 3.0 months (95% CI 0.8-5.3). QAPFS based on the QLU-C10D for the Kd maintenance group was 17.5 months (95% CI 15.9; 19.2) and 14.0 months (95% CI 12.4; 15.5) for the observation group; difference = 3.5 months (95% CI 1.1-5.9). CONCLUSIONS: Kd maintenance therapy after salvage ASCT did not adversely affect overall HRQL, but adjustment for HRQL reduced the PFS compared to unadjusted PFS. PFS of maintenance therapy should be quality-adjusted to balance the benefits and HRQL impact.

18F-Fluorodeoxyglucose positron emission tomography/computed tomography (PET) positivity after first-line treatment with autologous stem cell transplantation (ASCT) in multiple myeloma is strongly correlated with reduced progression-free and overall survival. However, PET-positive patients who achieve PET negativity after treatment seem to have comparable outcomes to patients who were PET negative at diagnosis. Hence, giving PET-positive patients additional treatment may improve their outcome. In this phase II study, we screened first-line patients with very good partial response (VGPR) or better after ASCT with PET. PET-positive patients received four 28-day cycles of carfilzomib-lenalidomide-dexamethasone (KRd). Flow cytometry-based minimal residual disease (MRD) analysis was performed before and after treatment for correlation with PET. Overall, 159 patients were screened with PET. A total of 53 patients (33%) were PET positive and 57% of PET-positive patients were MRD negative, demonstrating that these response assessments are complementary. KRd consolidation converted 33% of PET-positive patients into PET negativity. MRD-negative patients were more likely to convert than MRD-positive patients. In summary, PET after ASCT detected residual disease in a substantial proportion of patients in VGPR or better, even in patients who were MRD negative, and KRd consolidation treatment changed PET status in 33% of patients.

Summary: Iron metabolism and markers hereof are altered in anorexia nervosa (AN) but far from completely understood. We report a case of extreme hyperferritinemia in a patient with AN and discuss the possible mechanisms and current knowledge about the association between hyperferritinemia and AN. A 20-year-old woman with a history of AN presented with bradycardia, weariness, and malaise in addition to an incidentally very high ferritin level. The symptoms disappeared spontaneously after a short admission. There were no signs suggestive of systemic, hematological, or malignant disease causing the very high concentration of ferritin. Her body weight was in decline, leading up to admission, but did initially increase after discharge accompanied by declining ferritin concentration. However, a clear association between ferritin dynamics and weight changes or physical activity was not identified and neither were other causes of the hyperferritinemia. Around one in four patients with AN have increased ferritin concentrations. Our case represents the highest ferritin concentration reported in a patient with AN without other underlying causes or comorbidities. Learning points: Perturbed iron metabolism is frequent in restrictive type anorexia nervosa but incompletely understood. Altered ferritin in anorexia nervosa may be linked to nutritional status.
RESUMEN
BACKGROUND: Patients with hematological cancer who experience relapse or progressive disease often face yet another line of treatment and continued mortality risk that could increase their physical and emotional trauma and worsen their health-related quality of life. Healthcare professionals who use patient-reported outcomes to identify who will have specific sensitivities in particular health-related quality of life domains may be able to individualize and target treatment and supportive care, both features of precision medicine. Here, in a cohort of patients with relapsed or progressive hematological cancer, we sought to identify health-related quality of life domains in which they experienced deterioration after relapse treatment and to investigate health-related quality of life patterns. METHOD: Patients were recruited in connection with a precision medicine study at the Department of Hematology, Aalborg University Hospital. They completed the European Organization for Research and Treatment of Cancer questionnaire and the Hospital Anxiety and Depression Scale at baseline and at 3, 6, 9, and 12 months after the relapse diagnosis or progressive cancer. Modes of completion were electronically or on paper. Clinically relevant changes from baseline to 12 months were interpreted according to Cocks' guidelines. We quantified the number of patients with moderate or severe symptoms and functional problems and the number who experienced improvements or deterioration from baseline to 12 months. RESULTS: A total of 104 patients were included, of whom 90 (87%) completed baseline questionnaires and 50 (56%) completed the 12-month assessments. The three symptoms that patients most often reported as deteriorating were fatigue (18%), insomnia (18%), and diarrhea (18%). The three functions that patients most often reported as deteriorating were role (16%) and emotional (16%) and cognitive (16%) functioning. CONCLUSION: In this study, patient-reported outcome data were useful for identifying negatively affected health-related quality of life domains in patients with relapsed or progressive hematological cancer. We identified patients experiencing deterioration in health-related quality of life during treatment and characterized a potential role for patient-reported outcomes in precision medicine to target treatment and supportive care in this patient group.

OBJECTIVES: To evaluate health-care utilisation and costs, myeloma complications and survival in Danish patients with multiple myeloma (MM) before and after implementation of new early-line treatments in 2009. METHODS: Based on data from the Danish National Health Registers, 3518 patients diagnosed with MM during 2002-2005 or 2010-2013 and randomly matched control individuals were identified, and health-care utilisation and costs were estimated. RESULTS: Health-care utilisation showed a marked shift from inpatient admissions towards outpatient visits. From early to late period, the mean annual number of outpatient visits increased by 22% and 28% in patients <65 years and ≥65 years, respectively. Additionally, the mean annual outpatient service costs increased correspondingly from 17 001 to 23 643 in younger patients and from 11 317 to 16 144 in the elderly. Increasing outpatient costs were outbalanced by lower inpatient admission costs and the adjusted total mean annual costs decreased in younger patients, probably partly due to fewer myeloma complications. The five-year survival rates increased markedly in both younger (HR = 0.51) and elderly (HR = 0.69) patients. CONCLUSION: Despite the introduction of new expensive early-line MM treatments in 2009, health-care costs remained stable due to a shift in health-care utilisation towards outpatient clinic care and fewer complications.

PURPOSE: Results of patient-reported outcome measures (PROMs) are increasingly used to inform healthcare decision-making. Research has shown that response shift can impact PROM results. As part of an international collaboration, our goal is to provide a framework regarding the implications of response shift at the level of patient care (micro), healthcare institute (meso), and healthcare policy (macro). METHODS: Empirical evidence of response shift that can influence patients' self-reported health and preferences provided the foundation for development of the framework. Measurement validity theory, hermeneutic philosophy, and micro-, meso-, and macro-level healthcare decision-making informed our theoretical analysis. RESULTS: At the micro-level, patients' self-reported health needs to be interpreted via dialogue with the clinician to avoid misinterpretation of PROM data due to response shift. It is also important to consider the potential impact of response shift on study results, when these are used to support decisions. At the meso-level, individual-level data should be examined for response shift before aggregating PROM data for decision-making related to quality improvement, performance monitoring, and accreditation. At the macro-level, critical reflection on the conceptualization of health is required to know whether response shift needs to be controlled for when PROM data are used to inform healthcare coverage. CONCLUSION: Given empirical evidence of response shift, there is a critical need for guidelines and knowledge translation to avoid potential misinterpretations of PROM results and consequential biases in decision-making. Our framework with guiding questions provides a structure for developing strategies to address potential impacts of response shift at micro-, meso-, and macro-levels.

BACKGROUND: COVID-19, caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), has great health implications in older patients, including high mortality. In general, older patients often have atypical symptom presentations during acute illness due to a high level of comorbidity. The purpose of this study was to investigate the presentation of symptoms at hospital admissions in older patients with COVID-19 and evaluate its impact on disease outcome. METHODS: This retrospective study included patients ≥80 years of age with a positive test for SARS-CoV-2, who were admitted to one of three medical departments in Denmark from March 1st to June 1st, 2020. RESULTS: A total of 102 patients (47% male) with a mean age of 85 years were included. The most common symptoms at admission were fever (74%), cough (62%), and shortness of breath (54%). Furthermore, atypical symptoms like confusion (29%), difficulty walking (13%), and falls (8%) were also present. In-hospital and 30-day mortality were 31% (n = 32) and 41% (n = 42), respectively. Mortality was highest in patients with confusion (50% vs 38%) or falls (63% vs 39%), and nursing home residency prior to hospital admission was associated with higher mortality (OR 2.7, 95% CI 1.1-6.7). CONCLUSIONS: Older patients with SARS-Cov-2 displayed classical symptoms of COVID-19 but also geriatric frailty symptoms such as confusion and walking impairments. Additionally, both in-hospital and 30-day mortality was very high. Our study highlights the need for preventive efforts to keep older people from getting COVID-19 and increased awareness of frailty among those with COVID-19.

Patients with multiple myeloma (MM) report high symptom burden and functional disabilities resulting in impaired health-related quality of life (HRQoL). Effective evidence-based rehabilitation guidelines are needed for patients with MM to improve HRQoL. The primary aim of this study was to investigate HRQoL in patients with rehabilitation needs living their everyday life. Patients with MM in remission attended a 12-week multidisciplinary rehabilitation program including a 5-day residential course, home-based exercise and a 2-day follow-up course. The patients were referred by the treating haematologist and completed a booklet of validated HRQoL questionnaires at baseline and before arriving for the 2-day follow-up course. The proportion of participants with moderate to severe symptoms and functional problems were assessed at the two time points and multivariate logistic regression was used to investigate explaining factors of impaired HRQoL at baseline. Ninety-two patients participated with a follow-up compliance rate of 90%. Median age was 67 years and median time since diagnosis was 26 months (ranged 5 months to 15.6 years). The most frequently reported symptoms were global quality of life, role functioning, fatigue, pain, peripheral neuropathy and physical functioning. Pain and fatigue were both highly coherent with impairment in physical functioning and those two symptoms explained most HRQoL impairments. Overall, the participants reported no change in HRQoL after the 12-week rehabilitation program. The study supports the need for an evidence-based guideline for rehabilitation and palliative care to patients with MM in remission living their everyday life.

In 2019 the UK Myeloma Research Alliance introduced the Myeloma Risk Profile (MRP) for prediction of outcome in patients with newly diagnosed multiple myeloma (MM), ineligible for autologous stem cell transplantation. To validate the MRP in a population-based setting we performed a study of the entire cohort of transplant ineligible MM patients above 65 years in the Danish National MM Registry. Our data confirmed the value of the MRP. In a cohort of 1,377 patients, the MRP score separated patients into three distinct risk-groups with an observed hazard ratio of 2.91 for early death in high-risk versus low-risk patients.

Data on the impact of long term treatment with immunomodulatory drugs (IMiD) on health-related quality of life (HRQoL) is limited. The HOVON-87/NMSG18 study was a randomized, phase 3 study in newly diagnosed transplant ineligible patients with multiple myeloma, comparing melphalan-prednisolone in combination with thalidomide or lenalidomide, followed by maintenance therapy until progression (MPT-T or MPR-R). The EORTC QLQ-C30 and MY20 questionnaires were completed at baseline, after three and nine induction cycles and six and 12 months of maintenance therapy. Linear mixed models and minimal important differences were used for evaluation. 596 patients participated in HRQoL reporting. Patients reported clinically relevant improvement in global quality of life (QoL), future perspective and role and emotional functioning, and less fatigue and pain in both arms. The latter being of large effect size. In general, improvement occurred after 6-12 months of maintenance only and was independent of the World Health Organisation performance at baseline. Patients treated with MPR-R reported clinically relevant worsening of diarrhea, and patients treated with MPT-T reported a higher incidence of neuropathy. Patients who remained on lenalidomide maintenance therapy for at least three months reported clinically meaningful improvement in global QoL and role functioning at six months, remaining stable thereafter. There were no clinically meaningful deteriorations, but patients on thalidomide reported clinically relevant worsening in neuropathy. In general, HRQoL improves both during induction and maintenance therapy with immunomodulatory drugs. The side effect profile of treatment did not negatively affect global QoL, but it was, however, clinically relevant for the patients. (Clinicaltrials.gov identifier: NTR1630).

PURPOSE: The quality of patient-reported outcome (PRO) data can be compromised by non-response (NR) to scheduled questionnaires, particularly if reasons for NR are related to health problems, which may lead to unintended bias. The aim was to investigate whether electronic reminders and real-time monitoring improve PRO completion rate. METHODS: The population-based study "Quality of life in Danish multiple myeloma patients" is a longitudinal, multicentre study with consecutive inclusion of treatment-demanding newly diagnosed or relapsed patients with multiple myeloma. Education of study nurses in the avoidance of NR, electronic reminders, 7-day response windows and real-time monitoring of NR were integrated in the study. Patients complete PRO assessments at study entry and at 12 follow-up time points using electronic or paper questionnaires. The effect of the electronic reminders and real-time monitoring were investigated by comparison of proportions of completed questionnaires before and after each intervention. RESULTS: The first 271 included patients were analysed; of those, 249 (85%) chose electronic questionnaires. Eighty-four percent of the 1441 scheduled PRO assessments were completed within the 7-day response window and 11% after real-time monitoring, achieving a final PRO completion rate of 95%. A significant higher proportion of uncompleted questionnaires were completed after the patients had received the electronic reminder and after real-time monitoring. CONCLUSIONS: Electronic reminders and real-time monitoring contributed to a very high completion rate in the study. To increase the quality of PRO data, we propose integrating these strategies in PRO studies, however highlighting that an increase in staff resources is required for implementation.

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.

OBJECTIVES: The Danish Myeloma Study Group initiated a randomized, placebo-controlled, double-blinded phase II study to investigate the efficacy of adding clarithromycin to cyclophosphamide-bortezomib-dexamethasone (VCD) induction therapy in transplant eligible, newly diagnosed multiple myeloma patients. The study was prematurely terminated due to severe complications, and no effect of adding clarithromycin was found. The aim of this study was to compare health-related quality of life (HRQoL) between the two groups and to explore the coherence hereof with adverse event (AE) registration by clinicians. METHODS: Patients completed three validated HRQoL questionnaires at inclusion, before cyclophosphamide priming, and two months after high-dose therapy (HDT). The mean score difference was interpreted by clinically relevant differences between groups. Spearman's correlation analysis was used to compare patient-reported toxicities with AEs. RESULTS: Of 58 included patients, 55 participated in the HRQoL reporting. Before cyclophosphamide priming, patients in the clarithromycin group reported clinically relevant reduced HRQoL for eleven domains with persistent reduction in four domains two months after HDT. Poor correlation between patient-reported toxicities and clinician-reported AEs was observed. CONCLUSIONS: Despite the premature study termination, our data demonstrate impaired HRQoL when clarithromycin was added to the VCD regimen. We found clear underreporting of toxicities by clinicians. ClinicalTrials.gov number NCT02573935.

BACKGROUND: The objective of this randomized placebo-controlled study was to investigate the efficacy and safety of clarithromycin in combination with bortezomib-cyclophosphamide-dexamethasone (VCD) in patients with newly diagnosed multiple myeloma eligible for high-dose therapy. METHODS: Patients were randomized to receive tablet clarithromycin 500 mg or matching placebo tablet twice daily during the first 3 cycles of VCD induction therapy. Primary endpoint was to compare the rate of very good partial response (VGPR) or better response after three cycles of VCD combined with clarithromycin or placebo. RESULTS: The study was prematurely stopped for safety reasons after the inclusion of 58 patients (36% of the planned study population). The patients were randomly assigned to clarithromycin (n = 27) or placebo (n = 31). VGPR or better response after the VCD induction therapy was obtained in 12 patients (44.4%, 95% CI 25.5-64.7) and in 16 patients (51.6%, 33.1-69.8) (p = 0.59) in the clarithromycin group and the placebo group, respectively. Seven patients (25.9%) in the clarithromycin group developed severe gastrointestinal complications (≥ grade 3) comprising pain, neutropenic enterocolitis, paralytic ileus or peptic ulcer. These complications occurred in only one patient in the placebo group. Septicemia with Gram negative bacteria was observed in 5 patients in the clarithromycin group in contrast to one case of pneumococcal septicemia in the placebo group. Patient-reported QoL were negatively affected in the clarithromycin group compared to the placebo group. CONCLUSION: The study was prematurely stopped due to serious adverse events, in particular serious gastrointestinal complications and septicemia. The response data do not suggest any effect of clarithromycin when added to the VCD regimen. The combination of clarithromycin and bortezomib containing regimens is toxic and do not seem to offer extra anti-myeloma efficacy.Trial registration EudraCT (no. 2014-002187-32, registered 7 October 2014, https://www.clinicaltrialsregister.eu/ctr-search/trial/2014-002187-32/DK) and ClinicalTrials.gov (no NCT02573935, retrospectively registered 12 October 2015, https://www.clinicaltrials.gov/ct2/show/NCT02573935?term=Gregersen&cntry=DK&rank=9).
RESUMEN
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.
