When a randomized trial (NMSG 4/90) comparing treatment with melphalan/prednisone to melphalan/ prednisone + interferon alpha-2b in newly diagnosed multiple myeloma was initiated in 1990, a quality-of-life assessment was integrated into the study. We used the questionnaire (QLQ-C30) developed by the European Organization of Research and Treatment of Cancer (EORTC) Study Group on Quality of Life. The QLQ-C30 incorporates five functional scales, three symptom scales, a global health and quality-of life scale and some single symptom measures. The questionnaire was completed prior to treatment and after 1, 6, 12, 24, 36 and 48 months. 524 (90.2%) of 581 patients enrolled in the NMSG 4/90 completed the first questionnaire, and 484 (83.3%) completed all questionnaires given to them. All but one of the scales met the minimum criteria of reliability (Cronbach's alpha >/ 0.70). Validity was shown by (1) the ability of the scales to discriminate clearly between patients differing in clinical status as defined by pretreatment W.H.O. performance index and Durie & Salmon stage, and (2) the sensitivity to changes in objective disease status (response and relapse). This is the first report of the measurement of health-related quality of life in a prospective clinical trial in multiple myeloma. The results demonstrate that the QLQ-C30 is a reliable and valid instrument for the measurement of quality of life in these patients. The data will be used for a cost-utility analysis of the results of the NMSG 4/90 trial.

Measurement of health-related quality of life was integrated into a randomized trial (NMSG 4/90) comparing melphalan/prednisone to melphalan/prednisone + interferon alpha-2b in newly diagnosed multiple myeloma. One of the aims of the study was to assess the prognostic significance of quality-of-life scores, using the EORTC QLQ-C30 questionnaire. Univariate analysis showed a highly significant association with survival from the start of therapy for physical functioning as well as role and cognitive functioning, global quality of life, fatigue and pain. In multivariate analysis, physical functioning and W.H.O. performance status were independent prognostic factors (P values = 0.001 for both) when analysed in a Cox regression model with the somatic variables beta-2 microglobulin, skeletal disease and age. The best prediction for survival from the start of therapy was obtained by combining the beta-2 microglobulin and physical functioning scores in a variable consisting of three risk factor levels with an estimated median survival of 17, 29 and 49 months, respectively. At a 12 months landmark analysis, the relative risk for patients with physical functioning score 0-20 v 80-100 was 5.63 (99% CI 2.76-11.49), whereas the relative risk for patients without an objective response to chemotherapy compared to those with at least a minor response was 2.32 (99% CI 1.44-3.74). Quality-of-life assessment may be an independent and valuable addition to the known prognostic factors in multiple myeloma.

The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Study Group has adopted a modular approach to quality of life (QoL) assessment in cancer clinical trials. The core instrument (the EORTC QLQ-C30) covers a range of QoL issues relevant to a broad spectrum of patients with cancer. The QLQ-C30 is designed to be supplemented by more specific subscales ('modules') to assess aspects of QoL of particular importance to specific subgroups of patients. Since individual members of the study group were to be involved in module development, guidelines were established. The primary aim of these guidelines was to standardize the module development process in order to ensure uniformly high quality across modules. This paper gives an update of the work completed to date. First, while the guidelines proved practical for module development, producing modules that exhibit adequate levels of psychometric and cross-cultural validity, experience pointed to three areas where the guidelines required more precision. These amendments will be provided and include (1) stricter monitoring of the developmental process from within the study group, (2) the explicit requirement of involvement of the study group and (3) a more precise definition of the criteria to be fulfilled before modules are allowed to be called 'EORTC modules'. Second, an overview of the modules currently under development or available for general use is provided. These modules include those for body image, high-dose chemotherapy, leukaemia, myeloma, palliative care and the following cancers: bladder, brain, breast, colorectal, head and neck, lung, oesophageal, ophthalmic, ovarian, pancreas and prostate. Finally, the need for the coordination of efforts in module development, both from within and outside the EORTC, is discussed.

A multiple myeloma-specific quality-of-life questionnaire module has been designed in collaboration with the EORTC Quality-of-Life Study Group to be used in clinical trials with the EORTC QLQ-C30, a general cancer questionnaire. Strict methodology was employed to ensure thorough and appropriate development of the module. An extensive literature review was performed to identify health-related quality-of-life issues relevant to patients with multiple myeloma. Semi-structured interviews were then carried out in several European countries with health-care providers experienced in the treatment of patients with multiple myeloma, and with a group of patients with multiple myeloma, to identify the issues which were most important to patients. A questionnaire was devised from the list of issues, using a 1-week time-frame and response categories consistent with the EORTC QLQ-C30. The provisional questionnaire and the EORTC QLQ-C30 were administered to patients with multiple myeloma in each participating country with further semi-structured interviews to refine the content and design of the questionnaire. A review of the results obtained in each stage of development resulted in a 24-item myeloma-specific module, the EORTC QLQ-MY24, which assesses disease-specific symptoms and their impact on everyday life, treatment side-effects, social support, and future perspective. The module is currently undergoing further international field-testing to assess its psychometric properties.

The effect of interferon on the health-related quality of life in multiple myeloma was assessed in two trials carried out by the Nordic Myeloma Study (Group (NMSG). In both trials, the EORTC QLQ-C30 questionnaire, supplemented with 11 items relating to interferon toxicity, was used. The first was a randomized controlled trial (NMSG 4/90) evaluating the addition of interferon alpha-2b to melphalan and prednisone during induction, maintenance and relapse. During the first 12 months, patients on interferon reported more chills, fever, fatigue, pain, nausea/vomiting, appetite loss and dry skin than the control patients, and a slight reduction of global health and quality of life. From 12 months onward there were no significant differences in any score between the two groups. In a later trial (NMSG 5/94) evaluating the effect of high-dose chemotherapy with stem cell support in patients under 60 years of age with newly diagnosed myeloma, interferon was used as maintenance. During the maintenance phase, symptom and toxicity scores were not significantly different from those in control patients under 60 years of age in the previous trial. Thus, interferon appeared to be well tolerated after high-dose chemotherapy with stem cell support.

We evaluated the costs and the cost utility of high-dose melphalan and autologous stem cell support followed by interferon maintenance relative to conventional treatment with melphalan and prednisone, in patients less than 60 yr of age with multiple myeloma. From March 1994 to July 1997, 274 patients with newly diagnosed, symptomatic multiple myeloma were enrolled in a prospective, non-randomized, population-based, multicenter study to evaluate the treatment with high-dose melphalan and autologous blood stem cell support. Health-related quality-of-life was measured prior to treatment and during follow-up, using the EORTC QLQ-C30 questionnaire. Resource consumption was also recorded prospectively. The intensive treatment yielded a significant increase in median survival time from 44 to 62 months compared to conventionally treated patients. The corresponding gain in quality-adjusted life years (QALY) was found to be 1.2. Cost per QALY gained by the treatment with high-dose melphalan and autologous blood stem cell support was estimated at NOK 249,000 (USD 27,000).

Between May 1994 and May 2000, we autotransplanted 48 consecutive patients, 21 females and 27 males aged over 60 years (range: 60-78, median: 63). Sixteen patients had multiple myeloma (MM), 14 high-grade non-Hodgkin's lymphoma (HGNHL), six low-grade non-Hodgkin's lymphoma (LGNHL), nine acute myeloid leukemia (AML), one chronic lymphocytic leukemia (CLL), one Hodgkin's disease (HD) and one breast cancer; the performance status (WHO) was 0-1. Seventeen patients were in 1st CR (35.4%) and one in 2nd CR (2.1%), 25 in PR (52.1%), while five patients had been transplanted with progressive disease (10.4%); seven patients with MM received a double transplant. Patients received high-dose therapy including melphalan alone (13) or associated with other drugs (26), busulfan-cyclophosphamide (three), BEAM (11) and TBI (two). All patients took a median of 11 (range: 8-25) days to reach neutrophils >500/microl, 13 (range: 9-83) days to reach platelets > 20,000/microl and 17 (range: 11-83) days to reach platelets > 50,000/microl. Hematological toxicity, hospital stay and supportive care did not differ from those of a cohort of younger patients. At present, 31 patients are alive (14 in CR, five in PR, five in PD and seven in relapse) and 16 died from PD at a median follow-up of 37 months (1-67). Only one patient died from transplant-related toxicity. Quality of life, evaluated using a QLQ-C30 questionnaire in 25 patients at day +90, was good. In our experience PBPC mobilization and transplantation is feasible in patients aged > or = 60 years and the toxicity of this procedure is acceptable, with an early transplant-related mortality of 1.8%; therefore patients with hematological malignancies potentially curable with high-dose therapy (HDT) should also be candidates for HDT.

In a population-based study, the Nordic Myeloma Study Group found a survival advantage for high-dose melphalan with autologous blood stem-cell support compared to conventional chemotherapy in myeloma patients under 60 yr of age (risk ratio: 1.62; confidence interval [CI] 1.22-2.15; p = 0.001). A study of health-related quality of life (HRQoL) was integrated in the trial, using the EORTC QLQ-C30 questionnaire. Of the 274 patients receiving intensive therapy 221 (81%) were compared to 113 (94%) of 120 patients receiving conventional melphalan-prednisone treatment. Prior to treatment, there were no statistically significant differences in any HRQoL score between the two groups. One month after the start of induction chemotherapy, the patients on intensive treatment had more sleep disturbance than the control patients. At 6 mo, corresponding to a mean of 52 d after high-dose melphalan, the patients on intensive treatment had moderately lower scores for global QoL and role and social functioning and there was also a significantly higher score for appetite loss. At 12 and 24 mo, the HRQoL was similar to that of the control patients. At 36 mo, there was a trend toward less fatigue, pain, nausea, and appetite loss in the intensive-treatment group. Thus, the 18 mo of prolonged survival seem to be associated with a good health-related quality of life. Despite the moderate HRQoL reduction associated with the early intensive chemotherapy phase, this treatment modality must be regarded as an important step forward in the care of multiple myeloma.

Questionnaires on the quality of life and tolerance of different parts of maintenance treatment were sent to a total of 83 patients with multiple myeloma. All patients were for more than one year on maintenance treatment which involved either interferon alpha monotherapy (I), 3 million u. three times per week till signs of relapse developed or sequence administration of interferon alpha and dexamethazone 40 mg on day 1 to 4, 10 to 13 and 20 to 23 and then after a four-week interval again interferon alpha, again till progression of the disease occurred. The patients evaluated the presence or absence of different undesirable effects of treatment during the first two weeks of treatment and throughout the year and listed their intensity into four categories defined in the questionnaire. The quality of life was evaluated by means of a basic module of the questionnaire of the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire version 3.0 (EORTC QLQ-C30). The results of the questionnaire are to a certain extent surprising as from the patients' answers ensues that this maintenance treatment is associated with more numerous undesirable effects than the physicians realized when in contact with the patient. In this summary we can list only the most frequent effects (deterioration of eyesight, impaired sleep, depressions, irritability and unrest, chill, pain in muscles and joints, general weakness and dyspnoea). From the questionnaires on the quality of life ensues a markedly poorer quality of life of these patients as compared with the healthy population. There are however no basic differences between individual groups. The questionnaires were handed only to patients who had maintenance treatment for more than one year and thus patients were eliminated where maintenance treatment was discontinued because of undesirable effects. To give a general idea of the tolerance of the above maintenance treatment the authors mention that to the date of Aug. 31, 2001 113 patients were randomized into one of the branches of maintenance treatment. Maintenance treatment had to be discontinued in 6% patients (in two instances on account of severe hypothyroidism, in one case on account of hallucinations, in three instances on account of severe mental depression caused by this treatment). Reduction of interferon doses in 20% patients usually because of cytopenia but also on account of psychic problem. To the question what length of prolongation of life compensates the undesirable effects of maintenance treatment the following replies were obtained from patients receiving ID, possibly I: 3 months--47.6 and 38.3%, 6 months--4.3 and 10.6%, 9 months--0 and 4.3%, 12 months--47.6 and 46.8% of the addressed patients. In reply to the question whether the patients would prefer, assuming equal effectiveness, a maintenance monotherapy with interferon alpha or dexamethazone more patients preferred interferon to dexamethasone. For practice ensues from this article informing on undesirable effects of maintenance treatment and the effect of maintenance treatment on the quality of life: 1. the necessity of thorough knowledge of physicians of all possible undesirable effects as only a doctor knowing possible undesirable effects of treatment can recognize them, 2. regular monitoring not only of the activity of the basic disease, but also undesirable effects of maintenance treatment and the influence of treatment on the patients' quality of life, 3. the necessity to assess the quality of life in clinical trials as an important parameter for deciding on the way of treatment.

Long-term bisphosphonate therapy has been shown to offer clinical benefit in the management of multiple myeloma. This study sought to explore the feasibility and potential advantages of monthly home-based intravenous infusions of pamidronate in patients with multiple myeloma. In a prospective crossover, multicentre trial, 37 patients were randomly allocated to receive 3 months of treatment with pamidronate given in the home followed by 3 months of treatment with pamidronate given in hospital or vice versa. Results from a patient preference questionnaire indicated most patients preferred treatment at home. Quality-of-life measurement was undertaken using the EORTC QLQ-C30 questionnaire. The results indicated a small, generally consistent, although not statistically significant, trend in favour of home care treatment. Extra nursing specialist time was required for home therapy. Home therapy with pamidronate in patients with multiple myeloma appeared feasible and safe and was preferred by patients in this study.
