Abstract
BACKGROUND In 1986, the European Organization for Research and Treatment of Cancer (EORTC) initiated a research program to develop an integrated, modular approach for evaluating the quality of life of patients participating in international clinical trials. PURPOSE We report here the results of an international field study of the practicality, reliability, and validity of the EORTC QLQ-C30, the current core questionnaire. The QLQ-C30 incorporates nine multi-item scales: five functional scales (physical, role, cognitive, emotional, and social); three symptom scales (fatigue, pain, and nausea and vomiting); and a global health and quality-of-life scale. Several single-item symptom measures are also included. METHODS The questionnaire was administered before treatment and once during treatment to 305 patients with nonresectable lung cancer from centers in 13 countries. Clinical variables assessed included disease stage, weight loss, performance status, and treatment toxicity. RESULTS The average time required to complete the questionnaire was approximately 11 minutes, and most patients required no assistance. The data supported the hypothesized scale structure of the questionnaire with the exception of role functioning (work and household activities), which was also the only multi-item scale that failed to meet the minimal standards for reliability (Cronbach's alpha coefficient > or = .70) either before or during treatment. Validity was shown by three findings. First, while all interscale correlations were statistically significant, the correlation was moderate, indicating that the scales were assessing distinct components of the quality-of-life construct. Second, most of the functional and symptom measures discriminated clearly between patients differing in clinical status as defined by the Eastern Cooperative Oncology Group performance status scale, weight loss, and treatment toxicity. Third, there were statistically significant changes, in the expected direction, in physical and role functioning, global quality of life, fatigue, and nausea and vomiting, for patients whose performance status had improved or worsened during treatment. The reliability and validity of the questionnaire were highly consistent across the three language-cultural groups studied: patients from English-speaking countries, Northern Europe, and Southern Europe. CONCLUSIONS These results support the EORTC QLQ-C30 as a reliable and valid measure of the quality of life of cancer patients in multicultural clinical research settings. Work is ongoing to examine the performance of the questionnaire among more heterogenous patient samples and in phase II and phase III clinical trials.

Abstract
PURPOSE To construct a breast cancer-specific quality-of-life questionnaire (QLQ) module to be used in conjunction with the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and to test its reliability and validity cross-culturally. PATIENTS AND METHODS Module construction took place after the EORTC guidelines for module development. The module--the QLQ-BR23--consists of 23 items covering symptoms and side effects related to different treatment modalities, body image, sexuality, and future perspective. This module was tested in 170 Dutch, 168 Spanish, and 158 American cancer patients at two points in time. The timing for the Dutch and Spanish patients was before and during treatment with radiotherapy or chemotherapy. For the American patients, the questionnaire was administered at admission at the breast clinic and 3 months after the first assessment. RESULTS Multitrait scaling analysis confirmed the hypothesized structure of four of the five scales. Cronbach's alpha coefficients were, in general, lowest in Spain (range; .46 to .94) and highest in the United States (range; .70 to .91). On the basis of known-groups comparisons, selective scales distinguished clearly between patients differing in disease stage, previous surgery, performance status, and treatment modality, according to expectation. Additionally, selective scales detected change over time as a function of changes in performance status and treatment-induced change. CONCLUSION These results lend support to the clinical and cross-cultural validity of the QLQ-BR23 as a supplementary questionnaire for assessing specific quality-of-life issues relevant to patients with breast cancer.

Abstract
BACKGROUND Burnout and psychiatric morbidity among gastroenterologists, surgeons, radiologists, and oncologists in the UK have been estimated by means of a questionnaire-based survey. The relationship between consultants' mental health and their job stress and satisfaction, as well as their job and demographic characteristics, were also examined. METHODS Psychiatric morbidity was estimated using the 12-item General Health Questionnaire. The three components of burnout-emotional exhaustion, depersonalization, and low personal accomplishment-were assessed using the Maslach Burnout Inventory. Job stress and satisfaction were measured using study-specific questions. FINDINGS Of 1133 consultants, 882 (78%) returned questionnaires. The estimated prevalence of psychiatric morbidity was 27%, with no significant differences between the four specialist groups. Radiologists reported the highest level of burnout in terms of low personal accomplishment. Job satisfaction significantly protected consultants' mental health against job stress. Three sources of stress were associated with both burnout and psychiatric morbidity; feeling overloaded, and its effect on home life; feeling poorly managed and resourced; and dealing with patients' suffering. Burnout was also associated with low satisfaction in three domains: relationships with patients, relatives and staff; professional status/esteem; intellectual stimulation. In addition, being aged 55 years or less and being single were independent risk factors for burnout. Burnout was also more prevalent among consultants who felt insufficiently trained in communication and management skills. INTERPRETATION Consultants' mental health is likely to be protected against the high demands of medical practice by maintaining or enhancing job satisfaction, and by providing training in communication and management skills.

Abstract
The prevalence and causes of 'burnout' and psychiatric disorder among senior oncologists and palliative care specialists have been measured in a national questionnaire-based survey. All consultant non-surgical oncologists in the UK were asked to participate. Sources of work-related stress and satisfaction were measured using study-specific questions which were aggregated into factors. Psychiatric disorder was estimated using the 12-item General Health Questionnaire. The three components of 'burnout'--emotional exhaustion, depersonalisation and low personal accomplishment--were assessed using the Maslach Burnout Inventory. Three hundred and ninety-three out of 476 (83%) consultants returned their questionnaires. The estimated prevalence of psychiatric disorder in cancer clinicians was 28%, and this is similar to the rate among British junior house officers. The study group had equivalent levels of emotional exhaustion and low personal accomplishment to those found in American doctors and nurses, but lower levels of depersonalisation. Among cancer clinicians, 'burnout' was more prevalent among clinical oncologists than among medical oncologists and palliative care specialists. Psychiatric disorder was independently associated with the stress of feeling overloaded (P < 0.0001), dealing with treatment toxicity/errors (P < 0.004) and deriving little satisfaction from professional status/esteem (P = 0.002). 'Burnout' was also related to these factors, and in addition was associated with high stress and low satisfaction from dealing with patients, and with low satisfaction from having adequate resources (each at a level of P < or = 0.002). Clinicians who felt insufficiently trained in communication and management skills had significantly higher levels of distress than those who felt sufficiently trained. If 'burnout' and psychiatric disorder among cancer clinicians are to be reduced, increased resources will be required to lessen overload and to improve training in communication and management skills.

Abstract
In this paper the psychometric properties of the multidimensional fatigue inventory (MFI-20) are established further in cancer patients. The MFI is a 20-item self-report instrument designed to measure fatigue. It covers the following dimensions: general fatigue, physical fatigue, reduced activity, reduced motivation and mental fatigue. The instrument was used in a Dutch and Scottish sample of cancer patients receiving radiotherapy. The dimensional structure was assessed using confirmatory factor analyses (Lisrel's unweighted least-squares method). The hypothesised five-factor model appeared to fit the data in both samples (adjusted goodness of fit; AGFI: 0.97 and 0.98). Internal consistency of the separate scales was good in both the Dutch and Scottish samples with Cronbach's alpha coefficients ranging from 0.79 to 0.93. Construct validity was assessed by correlating the MFI-20 to activities of daily living, anxiety and depression. Significant relations were assumed. Convergent validity was investigated by correlating the MFI scales with a visual analogue scale measuring fatigue and with a fatigue-scale derived from the Rotterdam Symptom Checklist. Results support the validity of the MFI-20. The highly similar results in the Dutch and Scottish sample suggest that the portrayal of fatigue using the MFI-20 is quite robust.

Abstract
The EORTC Study Group on Quality of Life (the Study Group) has adopted a modular approach to quality of life (QOL) assessment in cancer clinical trials. A 'core' instrument-the QLQ-C30-has been designed to cover a range of QOL issues relevant to a broad spectrum of cancer patients. It is intended that this QLQ-C30 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 required to standardize the module development process in order to ensure uniformly high quality across modules. These guidelines are presented in this paper. The term 'module' is defined, the composition of modules is outlined, and the criteria used to develop modules are specified. The module development process, consisting of four phases (generation of relevant QOL issues, operationalization of the QOL issues into a set of items, pretesting the module questionnaire, and large-scale field-testing) is described in detail. Further, issues related to cross-cultural instrument development, and the need for monitoring the module development process from within the Study Group are discussed. Finally, experiences with developing two site-specific modules (i.e., for head and neck, and breast cancer), are presented and the extent to which the guidelines meet practical requirements is discussed. The guidelines appear to provide a practical tool for module construction, that can facilitate the development of a comprehensive system for assessing the QOL of cancer patients internationally.

Abstract
Prophylactic cranial irradiation (PCI) reduces the risk of cranial metastasis in small cell lung cancer (SCLC), but the magnitude and value of this reduction, the risks of radiation morbidity and whether PCI influences survival are unclear. We conducted a randomised trial in patients with limited-stage SCLC who had had a complete response to induction therapy. Initially, patients were randomised equally to (1) PCI 36 Gy in 18 daily fractions, (2) PCI 24 Gy in 12 fractions and (3) no PCI; subsequently, to increase the rate of accrual, randomisation was to clinicians' choice of PCI regimen versus no PCI (at a 3:2 ratio). The endpoints were appearance of brain metastases, survival, cognitive function, and quality of life (QoL). Three hundred and fourteen patients (194 PCI, 120 No PCI) were randomised. In the revised design, the most commonly used PCI regimens were 30 Gy in 10 fractions and 8 Gy in a single dose. With PCI, there was a large and highly significant reduction in brain metastases (HR = 0.44, 95% CI 0.29-0.67), a significant advantage in brain-metastasis-free survival (HR = 0.75, 95% CI 0.58-0.96) and a non-significant overall survival advantage (HR = 0.86, 95% CI 0.66-1.12). In both groups, there was impairment of cognitive function and QoL before PCI and additional impairment at 6 months and 1 year, but no consistent difference between the two groups and thus no evidence over 1 year of major impairment attributable to PCI. PCI can safely reduce the risk of brain metastases. Further research is needed to define optimal dose and fractionation and to clarify the effect on survival. Patients with SCLC achieving a complete response to induction therapy should be offered PCI.

Abstract
PURPOSE To evaluate alternative automated methods of collecting data on quality of life (QOL) in cancer patients. After initial evaluation of a range of technologies, we compared computer touch-screen questionnaires with paper questionnaires scanned by optical reading systems in terms of patients' acceptance, data quality, and reliability. PATIENTS AND METHODS In a randomized cross-over trial, 149 cancer patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, version 2.0 (EORTC QLQ-C30), and the Hospital Anxiety and Depression Scale (HADS) on paper and on a touch screen. In a further test-retest study, 81 patients completed the electronic version of the questionnaires twice, with a time interval of 3 hours between questionnaires. RESULTS Fifty-two percent of the patients preferred the touch screen to paper; 24% had no preference. The quality of the data collected with the touch-screen system was good, with no missed responses. At the group level, the differences between scores obtained with the two modes of administration of the instruments were small, suggesting equivalence for most of the QOL scales, with the possible exception of the emotional, fatigue, and nausea/vomiting scales and the appetite item, where patients tended to give more positive responses on the touch screen. At the individual patient level, the agreement was good, with a kappa coefficient from 0.57 to 0.77 and percent global agreement from 61% to 97%. The electronic questionnaire had good test-retest reliability, with correlation coefficients between the two administrations from 0.78 to 0.95, kappa coefficients of agreement from 0.55 to 0.90, and percent global agreement from 56% to 100%. CONCLUSION Computer touch-screen QOL questionnaires were well accepted by cancer patients, with good data quality and reliability.

Abstract
Forty-three patients with irresectable advanced pancreatic cancer were randomized to receive chemotherapy using a combination of 5-fluorouracil, Adriamycin and mitomycin or no chemotherapy. Groups were well matched with regard to age, extent of disease and performance status on entry. Chemotherapy was well tolerated and, although common, side-effects were usually mild. Psychological measurements based on the Hospital Anxiety and Depression score were made in 31 patients. These showed significantly less depression but not anxiety in the treated group immediately after randomization and following 2 months of chemotherapy. Median survival in the treated group was 33 (range 9-80) weeks compared with 15 (range 1-62) weeks in the untreated group (P < 0.002). Chemotherapy should be considered in all patients presenting with advanced inoperable pancreatic cancer.

Abstract
BACKGROUND The optimum dose and fractionation schedule for the palliative irradiation of painful bone metastases is controversial. PURPOSE To compare the efficacy, side-effects and effect on quality of life of two commonly used radiotherapy schedules in the management of painful bone metastases. MATERIALS AND METHODS In a prospective trial, 280 patients were randomised to receive either a single 10 Gy treatment or a course of 22.5 Gy in five daily fractions for the relief of localised metastatic bone pain. RESULTS Response rates have been calculated from 240 assessable treated sites of pain. The overall response rates were 83.7% (single treatment) and 89.2% (five fractions). The complete response rates were 38.8% (single treatment) and 42.3% (five fractions). The median duration of pain control was 13.5 weeks (single treatment) and 14.0 weeks (five fractions). None of these differences was statistically significant. There were no differences between the groups in the effect of treatment on a variety of quality of life parameters. CONCLUSIONS It is concluded that a single 10 Gy treatment is as effective as a course of 22.5 Gy in five fractions in the management of painful bone metastases.

Abstract
This study defines the psychometric properties of the European Organisation for Research and Treatment of Cancer (EORTC) quality of life (QOL) questionnaire designed to measure the QOL of patients with ovarian cancer. The ovarian cancer module (EORTC QLQ-OV28) was developed to supplement the EORTC QLQ-C30. The core questionnaire and the QLQ-OV28 were prospectively administered to 368 ovarian cancer patients after they had been treated with radical or debulking surgery followed by chemotherapy. The QLQ-OV28 module assesses abdominal/gastrointestinal symptoms, peripheral neuropathy, other chemotherapy side-effects, hormonal/menopausal symptoms, body image, attitude to disease/treatment and sexual functioning. Questionnaires were well accepted by patients, baseline compliance rates were 86%, 72% provided a second assessment, less than 3% of the items had missing data. Multi-trait scaling analyses confirmed the hypothesised scales. All hypothesised scales exhibited good psychometric properties. These results support the clinical and psychometric validity of the EORTC QLQ-OV28 module as a supplement to the EORTC QLQ-C30.

Abstract
A screening programme designed to identify cases of Major Depressive Disorder (MDD) in patients attending a Regional Cancer Centre outpatient department was established. It comprised two stages: (1) The Hospital Anxiety and Depression Scale (HADS) self-rating questionnaire administered by a touch-screen computer; (2) we interviewed patients with high scores on the HADS (15 or more total score) over the telephone using the depression section of the Structured Clinical Interview for DSMIV (SCID). A large consecutive sample (5613) of oncology clinic attenders was screened, and practical difficulties in the screening process were identified. The estimated prevalence of major depressive disorder (MDD) in the sample surveyed was approximately 8% (7.8%; 95% confidence intervals 6.9–8.5%). We assessed a consecutive series of 150 patients identified as having MDD to determine how many had received evidence-based treatment for MDD. Only half had discussed their low mood with their general practitioner, only one-third had been prescribed any antidepressant medication, and very few had taken a therapeutic dose for an adequate period. Very few had received psychological treatment or had been referred to mental health services. Most were receiving no potentially effective therapy.

Abstract
Cognitive function items are increasingly included in quality of life measures, and complaints of concentration and memory difficulties are often reported by cancer patients. The aim of this study was to examine the factors influencing patients' level of complaint by comparing subjective reports with objective test performance of a sample of adult lymphoma patients, disease-free and > or = 6 months after treatment. There was no significant difference between complainers and non-complainers in sociodemographic or clinical characteristics or in their performance on standard neuropsychometric tests of concentration and memory. Those reporting concentration and memory difficulties had significantly higher scores on measures of anxiety, depression and fatigue. This calls into question the validity of including cognitive function items in self-report quality of life measures. Patients who report concentration and memory difficulties should be screened for clinically significant and potentially remediable mood disorder. Objective testing remains the method of choice for assessing higher mental function.

Abstract
Women referred to a familial breast cancer clinic completed questionnaires before and after counselling and at annual follow-up to assess their risk estimate and psychological characteristics. The aims were to determine whether those who attended the clinic overestimated their risk or were highly anxious and whether counselling influenced risk estimates and levels of distress. Women (n = 450) at this clinic were more likely to underestimate (39%) than overestimate (14%) their risk. Mean trait anxiety scores were higher than general population data (t = 4.9, n = 1059, P<0.001) but not significantly different from published data from other screening samples. Overestimators (z = 5.69, P<0.0001) and underestimators (z = -8.01, P<0.0001) reported significantly different risk estimates (i.e. increased accuracy) after counselling, but significant inaccuracies persisted. Over- (n = 12) and underestimators (n = 60) were still inaccurate in their risk estimates by a factor of 2 after counselling. Thirty per cent of the sample scored above the cut-off (5/6) for case identification on a screening measure for psychological distress, the General Health Questionnaire (GHQ). GHQ scores were significantly lower after counselling (t = 3.6, d.f. = 384, P = 0.0004) with no evidence of increasing risk estimate causing increased distress. The risk of distress after counselling was greater for younger women and those who were more distressed at first presentation. The counselling offered was effective in increasing the accuracy of risk perceptions without causing distress to those who initially underestimated their risk. It is worrying that inaccuracies persisted, particularly as the demand for service has since reduced the consultation time offered in this clinic. Further work is needed to evaluate alternative models of service delivery using more sophisticated methods of assessing understanding of risk.

Forty to 50% reported persistent tiredness, lack of energy and weight gain. Sixty per cent had not resumed their full premorbid functional status. Mean scores for anxiety and depression were higher than general population means and this sample scored higher for psychological distress than published data quoted for disease free cancer patients. These women reported many concerns about cervical cancer, most commonly fear of recurrent disease (91%). More than one-third blamed themselves for the disease. There were no significant differences in functional outcome or psychological status between treatment groups or by age or time since treatment. Psychological distress scores were significantly correlated with physical complaints (P < 0.001) and functional outcomes (P < 0.02). For the 61 women who were sexually active, sexual function post-treatment was rated as significantly poorer than subjectively recalled premorbid sexual function (P < 0.005). RT treated patients were more likely to report pain on intercourse and loss of enjoyment. Psychological as well as physical problems were highly correlated with sexual outcome (P < 0.01) 44% were unable to talk adequately with their partners about their experience. The majority felt they needed more information about cervical cancer, its treatment and how to help themselves rehabilitate. Forty-nine per cent would have liked to have had counselling. Even with the same physical morbidity the functional, emotional and sexual status of these women could be improved by giving more attention to their psychological and sexual concerns.

Abstract
The Hospital Anxiety and Depression Scale (HADS) is widely used as a tool for assessing psychological distress in patients and non-clinical groups. Previous studies have demonstrated conflicting results regarding the factor structure of the questionnaire for different groups of patients, and the general population. This study investigated the factor structure of the HADS in a large heterogeneous cancer population of 1474 patients. It also sought to investigate emerging evidence that the HADS conforms to the tripartite model of anxiety and depression (Clark & Watson, 1993), and to test the proposal that detection rates for clinical cases of anxiety and depression could be enhanced by partialling out the effects of higher order factors from the HADS (Dunbar et al., 2000). The results demonstrated a two-factor structure corresponding to the Anxiety and Depression subscales of the questionnaire. The factor structure remained stable for different subgroups of the sample, for males and females, as well as for different age groups, and a subgroup of metastatic cancer patients. The two factors were highly correlated (r =.52) and subsequent secondary factor analyses demonstrated a single higher order factor corresponding to psychological distress or negative affectivity. We concluded that the HADS comprises two factors corresponding to anhedonia and autonomic anxiety, which share a common variance with a primary factor namely psychological distress, and that the subscales of the HADS, rather than the residual scores (e.g. Dunbar et al., 2000) were more effective at detecting clinical cases of anxiety and depression.

Abstract
In cross-national comparisons based on questionnaires, accurate translations are necessary to obtain valid results. Differential item functioning (DIF) analysis can be used to test whether translations of items in multi-item scales are equivalent to the original. In data from 10,815 respondents representing 10 European languages we tested for DIF in the nine translations of the EORTC QLQ-C30 emotional function scale when compared to the original English version. We tested for DIF using two different methods in parallel, a contingency table method and logistic regression. The DIF results obtained with the two methods were similar. We found indications of DIF in seven of the nine translations. At least two of the DIF findings seem to reflect linguistic problems in the translation. 'Imperfect' translations can affect conclusions drawn from cross-national comparisons. Given that translations can never be identical to the original we discuss how findings of DIF can be interpreted and discuss the difference between linguistic DIF and DIF caused by confounding, cross-cultural differences, or DIF in other items in the scale. We conclude that testing for DIF is a useful way to validate questionnaire translations.

Abstract
BACKGROUND Increasing demand for cancer genetics services has necessitated an urgent review of how these services are organized and, in particular, identification of an effective role for primary care. OBJECTIVES We aimed to assess the views of GPs on their role in cancer genetics services and their confidence in performing that role; to assess their understanding of cancer genetics, current practice and referral behaviour; and to identify needs for information and training to enable GPs to play an effective role in these services. METHOD A cross-sectional questionnaire survey of GPs was conducted through general practices in SE Scotland; 397 (response rate 59.3%) GPs returned a completed questionnaire. Outcome measures were: responders' perceptions of their role in cancer genetics services; confidence within that role; understanding of cancer genetics; current practice regarding patients presenting with concerns about their family history of cancer; and perceived information and training needs. RESULTS GPs identified their role to be: taking a family history; making appropriate referrals to specialist services; providing emotional support; teaching breast self-examination; and discussing need for screening. Lack of confidence within this role was reflected in low levels of understanding of cancer genetics and in inappropriate referral practices. Concerns were expressed about the increasingly specialist role demanded of primary care. A desire for referral guidelines and community genetics clinics was identified. CONCLUSIONS GPs readily identify a role for themselves in cancer genetics services, but admit to a lack of confidence in this area, calling for clear referral guidelines and specialist community support. Current inappropriate referral to specialist services results from a lack of confidence in estimating cancer risk, highlighting the need for the development of clear referral criteria. Given the rapidly increasing demand for cancer genetics services and the vital role of primary care, it is important to identify a model of these services that facilitates effective involvement of GPs without further increasing their workload.

Abstract
A video of introductory information about inherited susceptibility to breast cancer was made in consultation with clinicians in four Scottish cancer family clinics. One hundred and twenty-eight women, newly referred for breast cancer risk counselling were randomized to receive the video before (n = 66) or after (n = 62) counselling. Data were collected before randomization at clinic and by postal follow-up at 1 month. The Video Before group had shorter consultations with the breast surgeon (mean = 11.8 min+/-5.4 vs 14.6+/-7.2 for the Video After group). There was no difference between the groups in the accuracy of their risk estimate after counselling, although the Video Before group scored higher for self-reported (Z= 3.65, d.f. = 1, P < 0.01) and objectively assessed understanding (Z= 2.91, d.f. = 1, P < 0.01). At 1 month follow-up, the Video Before group were less likely to underestimate their risk estimate (38% vs 18%; chi2 = 4.62, d.f. = 1, P< 0.05), but there was then no difference between the groups in subjective or objective understanding. Use of the video was not associated with increased distress (GHQ, Spielberger State Anxiety) and was associated with greater satisfaction with the information given at the clinic. This study supports the value of videotape as a method of giving information to prepare women for breast cancer risk counselling. Observations of misunderstandings and distress emphasize the video should be seen as an aid to, not a substitute, for communications at the clinic.

Abstract
PURPOSE Systematic quality-of-life (QOL) assessment may have value in oncology practice by increasing awareness of a wide range of issues, possibly increasing detection of psychologic morbidity, social problems, and changes in physical status, and improving care and its outcomes. However, logistic problems are substantial. Automated systems solve many of these problems. We field-tested the feasibility and compliance that can be achieved using a computer touchscreen system in two consecutive studies. PATIENTS AND METHODS In study 1, a prospective cohort of 272 patients was offered QOL assessment at each clinic appointment for 6 months. In study 2, all patients (N = 1,291) were offered QOL assessment as part of clinic routine during a 12-week period. RESULTS In study 1, 82% of patients agreed to take part, but over time, compliance was poor (median, 40%; mean, 43%) and deteriorated with longer follow-up. In study 2, the overall compliance was greatly increased (median, 100%; mean, 70%), and compliance was retained over multiple visits. In study 1, compliance was better in younger patients, males, and socially advantaged patients, but was not affected by the presence of depression or anxiety, or QOL. In the second study, building on experience in the first study, data collection and storage in the computer system was excellent, achieving 98% of collected data stored in one center. In general, patients were comfortable with the computers and the approach. Data collection on the wards was more difficult and less complete than in clinics, especially for patients undergoing acute admissions. CONCLUSION Feasibility with higher compliance was demonstrated in study 2, in which the data collection was integrated into routine care, and can be improved with further technical initiatives and education of staff.

Abstract
A national questionnaire-based survey has found that palliative physicians report lower levels of burnout and similar levels of psychiatric morbidity than those reported by consultants in other specialties. To try to explain these findings, this study compared the sources of job stress and satisfaction reported by consultant palliative physicians with those reported by consultants working in four other specialties: surgery, gastroenterology, radiology and oncology. Stressful and satisfying aspects of work were assessed using questionnaires designed specifically for the study. The response rate for the palliative physicians was 126/154 (82%) and for the consultants in the other specialties 882/1133 (78%). Palliative physicians reported that feeling overloaded and its effect on home life made the greatest contribution to their job stress, and having good relationships with patients, relatives and staff made the greatest contribution to their job satisfaction. However, compared with the other specialist groups, palliative physicians reported less stress from overload (p < 0.001) and more satisfaction from having good relationships (p < 0.001). They also reported less stress and more satisfaction with the way they are managed and resourced (both p < 0.001). Hospital-based palliative physicians reported more stress and less satisfaction from their management and resources than their colleagues working in hospices (both p = 0.05). Thirty-five percent of palliative physicians felt insufficiently trained in communication skills and 81% felt insufficiently trained in management skills. Burnout was more prevalent among consultants who felt insufficiently trained in communication and management skills than among those who felt sufficiently trained. It is important therefore that effective training in communication and management skills are provided and that, at the very least, existing levels of resourcing and management practices within palliative medicine are maintained in order that physicians working in the specialty are able to provide care to dying patients without prejudicing their own mental health.

Abstract
BACKGROUND Cognitive deficits are the hallmark of dose limiting late radiation morbidity in the CNS. Little is known about the neuropsychometric morbidity of treatment in adults with primary brain tumours. We set out to evaluate systematically the neuropsychometric function of all long-term survivors in order to document the frequency and severity of impairment and study its relationship with tumour and treatment related parameters. MATERIALS AND METHODS 30 patients surviving in clinical and radiological remission for > 4 years following irradiation were recalled for clinical examination, CT/MRI scan and neuropsychometric testing. The 14 males, 16 females, (mean age 42.5 years), represented all but one long term survivors treated with radiotherapy in the Department of Clinical Oncology between 1971 and 1990. Twenty-five patients had a histological diagnosis of glioma. Patients treated before 1987 (n = 16) received whole brain irradiation (WBI); focused irradiation (FI) has been used since (n = 14). RESULTS The two groups were similar were in age, initial tumour type and surgical treatment, but the WBI group showed more evidence of neuropsychometric impairment than the FI group with significantly lower group median scores in tests of visuospatial organisation (WAIS Block Design, P = 0.01), visual memory (Rey Complex figure, P = 0.003) and complex information processing (Trails A, P = 0.003; Trails B, P = 0.002). Pre-morbid IQ estimated from sociodemographic variables, was comparable in the 2 groups which were not significantly different in their emotional state as assessed by the HADS. On univariate analysis radiation volume (P = 0.05) and time from treatment (P = 0.02) were the main factors associated with neuropsychometric deficit. Multivariate analysis by logistic regression confirmed WBI as the only independent predictor of neuropsychometric impairment (WBI vs. FI, odds ratio = 7.1, 95% C.I. 1.2-42.3, P = 0.03). CONCLUSIONS Neuropsychometric deficits are common and can be related to time from treatment and radiation technique. Neuropsychometric testing can be a useful tool in the evaluation of different treatment strategies.

Abstract
BACKGROUND/AIMS Endoscopic stent placement is the standard treatment for patients with extrahepatic malignant biliary strictures (EMBS) who are too frail to undergo surgical resection. Stenting relieves jaundice and pruritus but the effects upon other systemic symptoms and quality of life (QOL) are not known. METHODS Forty-seven patients (age: 46-89 years) with jaundice due to EMBS completed the European Organisation for Research and Treatment of Cancer QOL questionnaire, EORTC QLQ-C30, and two further questions assessing jaundice and pruritus, at the time of diagnosis and 1 month after endoscopic stenting. Thirty-eight patients successfully completed the study; nine patients succumbed to their illness within a month. RESULTS No significant difference was found in the baseline QOL measurements and liver function tests between those patients who completed the study and those who were either too weak to answer the questionnaire or died within the first month of stenting. For patients who successfully completed follow-up, liver function tests (apart from serum albumin) improved after stenting. They also reported significant improvement in emotional, cognitive and global health scores (P < 0.01). In addition to the expected improvement in pruritus and jaundice (P < 0.01), anorexia, diarrhoea and sleep pattern were also reported to be improved (P < 0.01). CONCLUSION Endoscopic stent insertion considerably improves a range of symptoms and enhances quality of life.

Abstract
A questionnaire was developed, according to the European Organization for Research and Treatment of Cancer (EORTC) published guidelines, to supplement the EORTC quality of life questionnaire-core 30 (QLQ-C30) to assess the quality of life (QL) of women with ovarian cancer treated in clinical trials. The provisional 28-item module, OV28, assesses abdominal symptoms; peripheral neuropathy; other chemotherapy side-effects; hormonal symptoms; body image; attitude to disease and treatment; and sexual functioning. The first 24 items of the module (excluding sexual functioning) were included in a UK multicentre trial (SCOTROC). The trial data were used for preliminary scaling analysis. Two problematic items were identified. When these were treated as single items along with the 'other chemotherapy side-effects' the instrument showed excellent scale properties. Mean scale scores discriminated between trial patients pre- and on chemotherapy. This is a promising tool for assessing the QL of women with ovarian cancer. The EORTC international field study (Protocol 15982) to assess more fully the psychometric properties of the OV28 is well underway.
