Self-reported late effects and long-term follow-up care among 1889 long-term Norwegian Childhood, Adolescent, and Young Adult Cancer Survivors (the NOR-CAYACS study)

Purpose

The majority of childhood, adolescent, and young adult cancer survivors (CAYACS) are at risk of late effects but may not receive long-term follow-up care for these. Here, we investigated (1) self-reported late effects, (2) long-term follow-up care, and (3) factors associated with receiving follow-up care in a population-based sample of Norwegian long-term CAYACS.

Methods

Survivors were identified by the Cancer Registry of Norway. All > 5-year survivors diagnosed between 1985 and 2009 with childhood cancer (CCS, 0–18 years old, excluding CNS), breast cancer (BC, stages I–III), colorectal cancer (CRC), leukemias (LEUK), non-Hodgkin lymphoma (NHL), or malignant melanoma (MM) at age 19–39 years were mailed a questionnaire (NOR-CAYACS study). Descriptive statistics and logistic regression models were used to analyze occurrence of late effects, long-term follow-up care for these, and associated factors.

Results

Of 2104 responding survivors, 1889 were eligible for analyses. Of these, 68% were females, with a mean age of 43 years at survey, on average 17 years since diagnosis, and diagnosed with CCS (31%), BC (26%), CRC (8%), NHL (12%), LEUK (7%), and MM (16%). Overall, 61.5% reported the experience of at least one late effect, the most common being concentration/memory problems (28.1%) and fatigue (25.2%). Sixty-nine percent reported not having received long-term follow-up care focusing on late effects. Lower age at survey (p = 0.001), higher education (p = 0.012), and increasing number of late effects (p = < 0.001) were associated with increased likelihood of follow-up care in the multivariate model.

Conclusions

The majority of survivors reported at least one late effect, but not receiving specific follow-up care for these. This indicates a need for structured models of long-term follow-up to ensure adequate access to care.

Sequences of talk about emotional concerns in follow-up consultations with adolescent childhood cancer survivors

OBJECTIVE

To explore practices regarding communication about emotional concerns in follow-up consultations with adolescent cancer survivors and pediatrician.

METHOD

Seven video-taped follow-up consultations with adolescent survivors which contained many examples of emotional cues and concern were analyzed according to principles of conversation analysis.

RESULTS

During talk about emotional concerns, a task-focused asymmetric pattern of pediatrician questions and patient responses was most often upheld. In a number of cases a gradual build-up of emotional expression from a weak hint to a more explicit expression of emotional concern was observed, often facilitated by the pediatricians. Most often work-up was relatively brief, sometimes with a brief positive reappraisal, but more comprehensive elaboration was also seen. Topic shifts were often abrupt.

CONCLUSION

Pediatricians and patients used some of the same conventions as in everyday conversation during emotional talk in medical encounters. We observed shifts between informal talk and a typical task-focused mode. Conscious attention to such shifts and to the sequential nature of emotional talk could be helpful for doctors in designing their responses to patients' emotional concerns.

PRACTICE IMPLICATIONS

Our findings may contribute to insight in how clinicians respond to emotional concerns in follow-up consultations and have implications for communication skills training.

Readability of Informed Consent Documents (1987–2007) for Clinical Trials: A Linguistic Analysis

We investigated the readability of informed consent documents linguistically and compared old and new ICDs. Twenty ICDs (ten from 1987–1992 and ten from 2006–2007) were included. The Evaluative Linguistic Framework (ELF) was used to analyze the texts. The ELF evaluates the following items: Main themes, order of themes, rhetorical functions, the relationship between reader and writer, meta-discourse, headings, expert terminology, and visual aspects. An ICD is considered readable if it achieves the goal of inviting the reader to participate and explaining the implication of participation. The new ICDs were more readable than the old ones, as they were more oriented towards research, contained instructions about how to consent, and provided clear contact information. Aspects that reduced the readability of the new ICDs were the large number of topics, details, and actors presented. The readability of the old ICDs was enhanced by fewer topics, a clear presentation of the involved actors, and brevity. However, their readability was reduced by the inclusion of a vast amount of information about the reader's diagnosis and treatment.

Using the Mini-Mental State Examination to screen for delirium in elderly patients with hip fracture

BACKGROUND

The main aim of this paper was to examine the usefulness of the Mini-Mental State Examination (MMSE) for screening delirium in elderly patients with hip fracture.

METHODS

The sample included 364 elderly patients with hip fracture admitted to two hospitals in Oslo. Delirium was assessed by the Confusion Assessment Method (CAM) as an approximation of the gold standard, DSM-IV. To evaluate the psychometric properties of the MMSE scale, we used the Mokken nonparametric latent trait model for unidimensional scaling.

RESULTS

In total, 76 (21%) patients were diagnosed with delirium based on the CAM, and 141 (43%) had preexisting cognitive impairment. As a screening tool, the recommended MMSE cut-point of 24 showed an acceptable sensitivity of 88% with a specificity of 54%. The prediction of delirium, based on logistic regression on the MMSE total score and on the 5 items selected by the stepwise logistic regression procedure, gave clearly less acceptable results.

CONCLUSIONS

Our study indicates that the MMSE may be useful in screening for delirium, but the high percentage of false positives shows that it does not have diagnostic potential in patients with hip fracture.

Alterations of gene expression in blood cells associated with chronic fatigue in breast cancer survivors

Fatigue is one of the most frequent complaints among breast cancer survivors. However, mechanisms underlying persisting fatigue after end of treatment are poorly understood. To explore whether biological processes underlying persistent fatigue can affect gene expression of blood cells, genome-wide expression analyses were performed on whole blood samples from breast cancer survivors classified as chronic fatigued 2-6 years after diagnosis. Non-fatigued survivors served as controls. Several gene sets involved in plasma- and B-cell pathways differed between the chronic fatigued and the non-fatigued, suggesting that a dysregulation in these pathways is associated with chronic fatigue and that a B-cell-mediated inflammatory process might underlie fatigue. The chronic fatigued also had a higher level of leucocytes, lymphocytes and neutrophiles compared with the non-fatigued, thus further indicating that an activation of the immune system plays a role in the biology of chronic fatigue in breast cancer survivors.

Sexual function in male lymphoma survivors versus matched controls: Relationship to age, gonadal hormones, and quality of life

9510

Background: Sexual function in male lymphoma survivors (LS) was examined and compared to age-matched controls from the general population (CTR). Methods: The study includes 294 LSs, diagnosed 1980–2002, treated at the Norwegian Radium Hospital, ≤50 years at diagnosis, with recent gonadal hormone levels [testosterone (T), SHBG, LH, and FSH]. Sexual function was assessed using the Brief Male Sexual Function Inventory (BSFI) consisting of 11 self-report items covering five domains: sexual drive, erectile function, ejaculatory function, problem assessment and overall satisfaction. Lower scores indicate impaired sexual function. A total BSFI score (T-BSFI) was constructed by summing all items except overall satisfaction. Mean and median scores for the BSFI domains and T-BSFI were compared across age groups (21–39, 40–49, 50–59, 60–69 years at survey), gonadal hormone levels [normal (n=144), elevated FSH only (n=60), low T and/or elevated LH (n=90)], cancer treatment intensity, comorbidity, relationship status, fatigue score, mental distress (HADS) and quality of life (SF-36, mental and physical health components). Multivariate linear regression analysis was performed with T-BSFI as the dependent variable including independent variables significant in univariate analyses. Each LS was matched to two CTRs (n=506). Results: Valid T-BSFI scores were available for 253 LSs (86%). Median age at survey was 48 years, median duration of follow-up 15 years, and 78% were in a committed relationship. LSs aged 40–59 years had significantly lower T-BSFIs compared to their CTRs (p≤0.01). All BSFI domain scores and T-BSFI decreased significantly with ageing. LSs with low T and/or elevated LH had the lowest BSFI domain and T-BSFI scores. Survivors with normal hormone levels had the highest scores. Low T and/or elevated LH (p=0.03), age ≥50 years at survey (p≤ 0.001) and mental distress (p< 0.001) were significantly associated with male sexual dysfunction (T-BSFI) in the multivariate analysis. Conclusions: LSs aged 40–59 years reported poorer sexual function than age-matched CTRs. Impaired sexual function was significantly associated with age ≥ 50 years at survey, having low T and/or elevated LH and being distressed.

Pain assessment tools in palliative care: an urgent need for consensus

At present, there is no universally accepted cancer pain assessment tool for use in palliative care (PC). The European Palliative Care Research Collaborative (EPCRC), therefore, aims to develop an international consensus-based computerised pain assessment tool. As part of this process, we have performed (1) a literature review on pain assessment tools for use in the PC and (2) an international expert survey to gain information on the relevant dimensions for pain assessment in PC. 230 publications were identified, only six met the inclusion criteria. Three further articles were identified through manual searching, totalling 11 different pain assessment tools. Nine tools were multidimensional. Pain intensity was assessed in seven, using various numerical/verbal rating scales (NRS/VRS); five tools focused on pain management. Three publications did not identify the rationale for the need to develop a new tool, and the selection procedure for items/dimensions was not described in six tools. Patient and/or professional expert groups were involved in the development of five tools and only two tools were extensively validated or cross-culturally tested. Thirty-two experts (71%) completed the expert survey and identified 'intensity', 'temporal pattern', 'relief/exacerbation', 'pain quality' and 'location' as the five most relevant dimensions. Most preferred assessment of 'pain intensity' was by NRS rather than VRS. Time windows extending 24 h were regarded as less relevant. Development of PC pain assessment tools seems to be a continuous process, which does not adhere to systematic guidelines, thus does not contribute to a universally accepted tool. No tool contained all relevant dimensions as defined by the experts. Many tools focused on particular dimensions, suggesting that specific research interests may drive the tool development process. Extensive literature reviews, expert and patient input and clinical studies are a needed approach in the development of a new consensus-based pain assessment tool.

Methods for handling missing data in palliative care research

Missing data is a common problem in palliative care research due to the special characteristics (deteriorating condition, fatigue and cachexia) of the population. Using data from a palliative study, we illustrate the problems that missing data can cause and show some approaches for dealing with it. Reasons for missing data and ways to deal with missing data (including complete case analysis, imputation and modelling procedures) are explored. Possible mechanisms behind the missing data are: missing completely at random, missing at random or missing not at random. In the example study, data are shown to be missing at random. Imputation of missing data is commonly used (including last value carried forward, regression procedures and simple mean). Imputation affects subsequent summary statistics and analyses, and can have a substantial impact on estimated group means and standard deviations. The choice of imputation method should be carried out with caution and the effects reported.

Drug addiction in hepatitis C patients leads to a lower quality of life

The subjective health status of hepatitis C patients has been relatively poorly studied. By using the Short Form 36 (SF-36), health-related quality of life (HRQOL) was assessed in a group of 42 hepatitis C patients. In all nine scales examined, the scores were generally low, and present drug use and being single were associated with especially large reductions in HRQOL. Compared with the Norwegian norms, scores were lower across all nine scales and significantly lower in eight. The study showed that the hepatitis C patients had definite reductions in HRQOL, but the impairment could not be fully explained by their hepatitis. Different non-viral factors such as drug use and marital status significantly influenced the results. This underlines the importance of taking other factors into account when studying the health status of hepatitis C patients.

A prospective study of health-related quality of life, fatigue, anxiety and depression 3-5 years after stem cell transplantation

Health-related quality of life (HRQOL), fatigue and psychological distress were prospectively assessed in 248 cancer patients treated with allogeneic (SCT, N=61), or autologous (ASCT, N=69) stem cell transplantation or conventional chemotherapy (CT, N=118) of whom 128 completed the assessments after 3 years. The European Organization for Treatment and Research of Cancer Core Quality of Life Questionnaire and the Hospital Anxiety and Depression Scale were administered nine (SCT/ASCT groups) or seven times (CT group) during the first year. The Fatigue Questionnaire was added at the final assessment. The SCT group displayed greater changes from baseline scores than the ASCT group, with more symptoms in the first months post transplant. A gradual improvement was found in both groups during the following 4-6 months, before stabilizing at baseline levels. Only minor changes were observed after the first year. All groups reported more fatigue than the population values after 3 years (P<0.01). The ASCT group also reported less optimal HRQOL (P<0.01-0.0001). No differences were found in anxiety and depression. Despite a faster recovery during the first months after transplant, the ASCT patients reported poorer functioning and more fatigue compared to the SCT group after 3 years. This suggests a need for a closer follow-up of these patients with special emphasis on functional status and fatigue.

Health status of patients with ankylosing spondylitis: a comparison with the general population

OBJECTIVE

To examine the subjective health in patients with ankylosing spondylitis (AS) compared with the general population, and to explore the associations between health status and age, sex of the patients, and educational level in AS.

METHODS

Health status was assessed with a generic instrument (SF-36) in 314 patients with AS and in 2323 people from the general population. Subgroup analyses were performed according to age, sex, and educational level. Standard difference scores (s-scores) were calculated to ensure the clinical meaningfulness of the norm based comparisons.

RESULTS

Both men and women with AS reported significantly impaired health on all scales of the SF-36. Women reported significantly worse health on physical health domains. However, when calculating differences from the general population, numerically larger s-scores were found for men (except for physical role and vitality). The relative impact of AS seems to diminish with increasing age. In AS, better health was significantly associated with higher education across all scales. Deviations from the general population on the non-physical health aspects were especially pronounced in patients with low education.

CONCLUSIONS

All key dimensions of health are affected by AS. The physical aspects seem to be most severely affected, but in the less educated group of patients, the disease impact on the mental health aspects was also considerable. Evaluation and management planning should take the complexity of AS into consideration. The focus on physical function should be maintained, and additional attention should be paid to the mental and social consequences of AS.

Physical exercise results in the improved subjective well-being of a few or is effective rehabilitation for all cancer patients?

Physical exercise as an intervention in cancer patients has attracted increasing interest. This review examines the published randomised controlled trials on physical exercise, during and after cancer treatment, focusing primarily on recruitment of patients, patient compliance, content of the intervention programmes and outcome measures. We performed systematic searches of PubMed, PsychInfo, Cancerlit and the Cochrane Library using the MESH terms exercise, neoplasms, cancer, rehabilitation and intervention. We identified 12 randomised trials with sample sizes ranging from 21 to 155 patients. Only four studies reported the number of patients assessed for eligibility and the reasons for exclusion; 15% to 30% of patients assessed for eligibility were randomised into the intervention programmes. Drop-out rates in the trials ranged from 0% to 34%. Most studies included female breast cancer patients (nine studies, 62% of total number of patients). Interventions included aerobic exercise training (10 studies) and resistance exercise (two studies). The studies used a wide range of instruments to assess health-related quality of life (HRQOL) and the physical exercise capacity. The studies indicated promising effects on both physiological and psychological outcomes. Randomised clinical studies are few, small in scope, and mainly focus on breast cancer patients. Complete knowledge about the type of physical exercise most beneficial for patients at different stages of the disease progression is still lacking. Future work should identify fewer and more specific endpoints.

Exercise reduces fatigue in chronic fatigued Hodgkins disease survivors--results from a pilot study

The aims of this pilot study were to compare aerobic capacity in non-fatigued and fatigued Hodgkin's disease survivors (HDS) and to assess the feasibility of an exercise-programme and its effects upon fatigue, physical functioning and aerobic capacity in chronic fatigued HDS. 53 HDS (85%) of originally 62 survivors treated at the Trondheim University Hospital in the period 1987-1997 completed a questionnaire including the Fatigue Questionnaire (FQ). 18 subjects were identified with chronic fatigue. 15 non-fatigued HDS matched for gender and age were drawn as controls. Both groups were invited to medical examination and exercise tests. All 15 fifteen non-fatigued HDS showed up to the medical examination. 12 of the 18 patients with chronic fatigue completed the tests and nine agreed to enter a home-based exercise intervention. Outcome measures were aerobic capacity, fatigue and physical functioning. No significant difference in aerobic capacity was found between the chronic fatigued HDS and the controls. Fatigue, physical functioning and maximal aerobic capacity were significantly improved after the intervention. Aerobic exercise had a positive effect upon chronic fatigue in HDS. However, the study is a pilot study and needs confirmation in a larger group of subjects. The intervention was well accepted, and the majority of the patients adhered to the programme.

Quality of life in advanced cancer patients: the impact of sociodemographic and medical characteristics

Population-based surveys have shown that health-related quality of life (HRQL) is influenced by patients' characteristics such as age, gender, living situation and diagnoses. The present study explores the impact of such factors on the HRQL of severely ill cancer patients. The study sample included 395 cancer patients who participated in a cluster randomised trial of palliative care. Median survival was 13 weeks. HRQL assessments (using the EORTC QLQ-C30 questionnaire) were compared among subgroups of relevant patients' characteristics (ANOVA), and the significance of individual covariates was explored by multivariate linear regression. Most EORTC QLQ-C30 scores showed minor differences between genders. Higher age was associated with less sleeping disturbance, less pain and better emotional functioning. No positive impact of living with a partner was found. Performance status and/or time from assessment to death were significantly associated with most functioning and symptom scores. We concluded that although the overall impact of sociodemographic characteristics may seem less important to HRQL scores among advanced cancer patients than in general populations, age and gender should be allowed for. Performance status and closeness to death also need to be reported.

Quality of life in palliative cancer care: results from a cluster randomized trial

PURPOSE

To assess the impact of comprehensive palliative care on patients' quality of life. The intervention was based on cooperation between a palliative medicine unit and the community service and was compared with conventional care.

PATIENTS AND METHODS

A cluster randomized trial was carried out, with community health care districts defined as the clusters. Patients from these districts who had malignant disease and survival expectancy between 2 to 9 months were entered onto the trial. The main quality-of-life end points were physical and emotional functioning, pain, and psychologic distress assessed monthly by using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) questionnaire and Impact of Event scale (IES). In total, 235 intervention patients and 199 controls were included.

RESULTS

During the initial 4 months of follow-up, the compliance was good (72%) and comparable among treatment groups. No significant differences on any of the quality-of-life scores were found. At later assessments and for scores that were made within 3 months before death, there was also no consistent tendency in favor of any treatment group on the main outcomes or other EORTC QLQ-C30 scales/items.

CONCLUSION

A general program of palliative care may be important to ensure flexibility and to meet the needs of terminally ill patients. However, to achieve improvements on a group level of the various dimensions of quality of life, specific interventions directed toward specific symptoms or problems may have to be defined, evaluated, and included in the program.

The self-perceived health status of Norwegian physicians compared with a reference population and foreign physicians

AIMS

To compare the self-perceived health status of a representative sample of Norwegian physicians with a general reference population; and to investigate differences in health status among groups of physicians.

METHODS

A cross-sectional postal survey was carried out of 1,126 Norwegian physicians and 1,742 subjects in a general reference population, using the widely used general health status questionnaire--Short Form 36 (SF-36). Scores were adjusted for differences in age, gender and education where applicable.

RESULTS

The health status of Norwegian physicians was better than that of subjects with a lower level of education in the four dimensions of the SF-36 related to physical health. Male physicians scored better on the physical functioning scale and lower on vitality and social functioning than comparable university graduates. Older physicians scored better than younger in dimensions related to mental health and social functioning. Norwegian general practitioners reported better health status than colleagues in Sweden and the UK.

CONCLUSIONS

The self-perceived health status of Norwegian physicians was as good or better than that of the general population. The cross-national differences could be caused by cultural differences, or be related to practice style or job strain.

[Occurrence and diagnosis of psychiatric conditions in palliative medicine]

BACKGROUND

The aims of the study are to describe the prevalence of psychiatric disorders in palliative care and how to diagnose these disorders.

MATERIAL AND METHODS

Literature search including cancer patients, palliative care, psychiatric conditions and diagnostics.

RESULTS

Neuropsychiatric conditions such as delirium, dementia and amnestic disorder are prevalent (> 20%), especially in the terminal phase. Anxiety and depressive symptoms are also common and may be caused by the patients' medical condition. Probably less than 10% have anxiety or depressive disorders. However, methodological limitations make comparisons across studies difficult. The interview is the main basis for assessment of mental status. Doctor-centered interviewing techniques are needed in the assessment of neuropsychiatric disorders. Emotional symptoms are best explored by open-ended questions and facilitating techniques. Psychiatric somatic symptoms such as weight loss, fatigue or insomnia are not valid diagnostic criteria. Selfreport questionnaires and short-form screening instruments are best suited for monitoring the course of the disorders, but must be adapted for this specific population.

INTERPRETATION

Neuropsychiatric conditions are the most prevalent psychiatric disorders in palliative care. Good interviewing skills are the main element in the diagnostic workup.

The burden of psoriasis: a study concerning health-related quality of life among Norwegian adult patients with psoriasis compared with general population norms

BACKGROUND

The reduction of disability caused by psoriasis is an important issue in dermatology. It is thus important to assess the patients' appraisal of their health-related quality of life.

OBJECTIVE

The aim of the present study was to assess health-related quality of life among patients with psoriasis and to compare these estimates with population norms.

METHODS

The samples comprised 283 patients and 2323 control subjects representative of the general Norwegian population. Health-related quality of life was assessed by means of the SF-36.

RESULTS

Both demographic and clinical variables, such as age, gender, educational level, hospital setting, comorbidity, and physical symptoms, affected the different SF-36 scales among the patients. After adjustments had been made for age, gender, and educational level, it was seen that psoriasis patients reported significantly lower scores than the normal controls on all scales. The greatest difference was found on the role emotional scale. The smallest difference was found on the health transition scale.

CONCLUSION

These results show that psoriasis patients report poorer health-related quality of life than the general population. Therefore patient care of psoriasis must give attention to the impact of the disease on different life domains.

Health-related quality of life and occurrence of intestinal side effects after pelvic radiotherapy--evaluation of long-term effects of diagnosis and treatment

Health-related quality of life (HRQOL) and occurrence of late intestinal side effects were assessed 3-4 years after pelvic radiotherapy for carcinoma of the endometrium and cervix. During 1988-1990, 143 women were included in a clinical trial to evaluate the effect of a low fat, low lactose diet on radiation-induced diarrhoea. Of 94 survivors, 79 (84%) answered the request. HRQOL was assessed by the EORTC QLQ-C36 and compared with population-based norms. The women scored lower than the general population on role functioning (81.5 versus 90.6 (p < 0.01)) and higher on diarrhoea (23.8 versus 9.5 (p < 0.01)). Compared with pre-treatment conditions, an increase in cases with pain in the lower back, hips and thighs was seen. Substantial pain and diarrhoea were associated with deterioration in HRQOL. In conclusion, few treatment and/or disease-related effects were detected 3-4 years after radiotherapy, with the exception of increased bowel frequency and pain in the lower back, hips and thighs.

High level of fatigue in lymphoma patients treated with high dose therapy

With the success of high dose therapy supported by autologous bone marrow transplantation (ABMT) for malignant lymphomas, medical late-effects and secondary effects on subjective health, like fatigue, are of concern. Fatigue is poorly understood and correlates have been barely addressed. Health-related quality of life (HRQL), fatigue, and correlates to fatigue, including endocrinological status and serum levels of interleukin-6, tumor necrosis factor, and soluble tumor necrosis factor receptors, were investigated in a cross-sectional study of 33 lymphoma patients (median age 39 years) 4-10 years after ABMT. The survivors were compared to general population norms. Fatigue was highly prevalent, and females reported significantly more fatigue and impaired HRQL compared to males and the normal population. Gonadal dysfunction was found in the majority of the patients, but no statistically significant endocrinological or immunological associations with fatigue could be demonstrated. The high level of fatigue among female long-term survivors after ABMT may be related to the gonadal dysfunction, but further studies of possible mechanisms behind fatigue are necessary.

Fatigue and psychiatric morbidity among Hodgkin's disease survivors

Fatigue is prevalent among cancer patients, including Hodgkin's disease survivors (HDS). Fatigue is poorly understood, and the clinical management is consequently difficult. This cross-sectional study examined how fatigue related to psychiatric morbidity among 457 HDS (aged 19-74 years, 56% males) treated during the period 1971-1991. The subjects were mailed a questionnaire including the Fatigue Questionnaire, the Hospital Anxiety and Depression Scale, and measures of previous psychiatric problems. Fatigue correlated moderately with anxiety and depression (r = 0.44 and 0.41 respectively). Twenty-six percent of the HDS had substantial fatigue for 6 months or longer (=cases). They had higher levels of anxiety (mean 7.3, 95% CI 6.4-8.1) and depression (mean 4.5, 95% CI 3.8-5.2) than the non-cases (anxiety: mean 4.3, 95% CI 3.9-4.7; depression: mean 2.1, 95% CI 1.8-2.5). Past psychiatric problems were not reported more commonly among the fatigue cases than among the non-cases. A multiple logistic regression analysis identified age (OR 1.04, 95% CI 1.02-1.06), anxiety (OR 1.2, 95% CI 1.2-1.3), and no self-reported psychiatric symptoms during treatment (OR 2.3, 95% CI 1.3-4.2) as predictors of fatigue caseness. One-half of the fatigue cases among HDS have psychological distress that might respond to treatment. Chronic fatigue among HDS is not predicted by previous psychiatric problems.

Health status of people with epilepsy compared with a general reference population

PURPOSE

To study the impact of epilepsy in a representative sample of people with epilepsy and compare with a normal reference population.

METHODS

We collected clinical and demographic data and information on health status by using the Short Form 36 (SF-36) questionnaire in two populations: (a) 397 patients with confirmed epilepsy attending a county hospital during a 7-year period, and (b) 1,663 patients from a random sample representative of the entire national population.

RESULTS

The respondents with epilepsy had well-regulated disease and showed the characteristics of a community sample: 70% had had no seizures during the last year, and 80% used antiepileptic drugs (AEDs). On six of eight SF-36 scales, patients with epilepsy had lower scores than the normal reference population, and they were less likely to be married, employed, or a full-time student. Seizure-free patients with epilepsy had scores close to those of the normal reference population, with higher scores on the social functioning and mental health scales and lower on the role--emotional scale. There were no differences in health status scores between seizure-free patients using and not using AEDs.

CONCLUSIONS

Our results confirm that patients with well-regulated epilepsy have a health status at the level of a general reference population.

The course of anxiety and depression during the first year after allogeneic or autologous stem cell transplantation

Psychological distress is frequently reported in transplant survivors. We prospectively assessed anxiety and depression before transplant, in the isolation period and during a follow-up period of 1 year. The Hospital Anxiety and Depression Scale (HADS) was administered to 131 cancer patients treated with high-dose chemotherapy followed by allogeneic (SCT) or autologous (ASCT) stem cell transplantation, and a concurrent group of 123 lymphoma patients receiving standard chemotherapy (CT) who served as a reference group. Relatively low levels of anxiety and depression were found. The level of anxiety slightly declined from baseline during follow-up (mean scores SCT: from 5.3 to 3.6, CT: from 6.0 to 4.2) or remained fairly stable (ASCT: from 5.4 to 4.8). The level of depression peaked when the transplant patients were in protective isolation or shortly thereafter (SCT: 6.1, ASCT: 6.4), but stabilized at baseline levels after 4 months. The highest level of depression in the CT group was reported 4 months after start of chemotherapy (3.4). Elevated levels of anxiety and depression at baseline predicted more anxiety and depression at the later assessments (P values < 0.0001). The ASCT group had higher levels of anxiety after 1 year (mean 4.8) than those found in the other two groups (SCT: 3.6, CT: 4.2), although they were not statistically significant. This study revealed lower than expected levels of anxiety and depression after intensive chemotherapy followed by SCT or ASCT. There was a decline in psychological distress during the 1-year follow-up period.

[Patients' quality of life after transplantation--what do we know?]

The number of organ transplantations has increased considerably over the last 30 years. The aim of organ transplantation is to increase the life expectancy of the patients and to give them a meaningful life with better quality. Transplantation of kidney, heart, lung, liver and bone marrow leads to considerably higher health-related quality of life. If the somatic adverse reactions are controlled, quality of life in transplant recipients is reported to be almost as good as in the general population.

Fatigue. Measures and relation to pain

Fatigue describes reduced capacity to sustain force or power output, reduced capacity to perform multiple tasks over time and simply a subjective experience of feeling exhausted, tired, weak or having lack of energy. Pain and fatigue have several components in common, such as being subjective, prevalent in most patients with cancer and caused by multiple factors of both a physical and psychological nature. In order to explore the relationship between fatigue and pain, data from five studies were used: two random samples from the Norwegian population (n=2323 and n=1965), Hodgkin's disease survivors (n=459), palliative care patients (n=434) and patients with bone metastases (n=94). All patients had completed one or more of the following instruments: EORTC QLQ-C30, SF-36 and/or Fatigue Questionnaire. The level of fatigue was much higher in the two palliative care populations (54.4 and 63.2) as compared to the normal population samples (25.0). Patients with bone metastases had significantly more pain (72.0) than the patients in the palliative care trial (47.4) and norms (20.5). In the two palliative care and bone metastases populations fatigue was almost unchanged over time, while pain was reduced. In the palliative care population a high level of fatigue (80.3) and pain (57.8) was reported 0-1 month before death. The relationship between pain, fatigue and the health-related quality of life domains should be explored in more detail, especially in follow-up studies in order to assess possible changes over time. In addition, the validity of the existing instruments measuring fatigue should be investigated for use in patients with advanced disease and short life expectancy.

Late medical sequelae after therapy for supradiaphragmatic Hodgkin's disease

A total of 221 consecutive early stage Hodgkin's disease (HD) patients were given mantle field irradiation only or in combination with chemotherapy in 1971-1991. In 1994 these patients responded to a mailed self-report questionnaire covering items on late medical symptoms. Of 200 patients (91%) who reported that their thyroid function had been tested, 110 patients (55% of those tested) had thyroid hypofunction at follow-up in 1994. Ninety-five patients (86% of patients with biochemical hypothyreosis) had started hormonal substitution. In 1993 and 1994, 101 of these patients who had received mantle field irradiation in 1980-1988 were called in for interview, clinical examination and thyroid function tests. Eighteen patients (18%) had started hormonal substitution treatment earlier, but 58 (70%) of the other 83 patients were found to have biochemical hypothyreosis. Of the 221 patients who completed the questionnaire, 66 patients (30%) reported dyspnoea on exertion for more than 3 years after treatment, 8 patients (4%) reported a history of myocardial infarction, 6 patients (3%) reported pericardial disease and 25 patients (11%) heart valve disease. Increased expenses incurred for dental care were reported by 106 patients (48%), increasing to 55% when Waldeyer's ring had been irradiated. The consequences of late sequelae after mantle field irradiation for future treatment are discussed.

Short form 36 (SF-36) health survey: normative data from the general Norwegian population

Anchoring health-related quality of life (HRQOL) measures in population norms makes clinical interpretations more meaningful and is in accordance with practice in other fields of medicine. In this paper norms for the Short Form 36 (SF-36) are presented in a random sample, representative of the general Norwegian population. In addition, sociodemographic variables affecting the scale scores are explored and discussed. The response rate was 67%, being lowest among subjects aged 70 years or over. Data-completeness strongly declined with increasing age. Physical health scales were also strongly affected by age. In all scales, with the exception of general health perceptions, women reported having poorer health than men. Marital status affected the four mental health scales. Educational status affected all the scales, but the effect was smallest in the mental scales. These norms can be employed for comparison in case-control studies, or to interpret HRQOL changes in prospective studies. Differences in social status should be given special attention. Caution should be exercised when assessing subjective health or employing the norms among subjects aged 70 years or over.

Hodgkin's disease: quality of life in future trials

It is of great importance to collect data of objective as well as subjective morbidity in patients cured for Hodgkin's disease. Such information may be used when new treatment strategies are discussed, in patients information and communication, to establish rehabilitation programs and to identify individuals who may benefit from rehabilitation. Measurement of health related quality of life (HRQOL) may give important information on how the cancer and/or the treatment has influenced the patients. There is no gold standard instrument for measurement of HRQOL in cancer. However, it is a consensus to use multidimensional patients rated measures with a standard format and scoring procedure. SF-36, EORTC QLQ-C30 and FACT are widely used in Europe and North America. Domain specific instruments includes a more comprehensive evaluation of a specific domain, for example anxiety or fatigue. Fatigue seems to be a prevalent symptom in Hodgkin's disease survivors and might affect patients' ability to perform normal activities and will often reduce their quality of life. Fatigue is defined as a subjective feeling of tiredness and might be measured by standardised and validated instruments such as the Fatigue Questionnaire (FQ) and the Multi-Dimensional Fatigue Inventory (MFI-20). Clinical significance might be defined as a meaningful difference based on consensus by the patient, the doctor and the society. In oncology there is no agreement of how long a meaningful difference in survival should be. For HRQOL a difference between 7 to 10 on a scale ranking from 0 to 100 has been regarded as clinical significant by some researchers. Another strategy to approach the issue of clinical significance is to use norms-estimates from the normal population- and/or reference estimates as guidelines. The long-term complication of the successful treatment of Hodgkin's disease reinforced the need for continued surveillance of treatment and related morbidities. Fatigue is a prevalent symptom and detailed diagnostic work-up is essential to identify patients with this problem. More knowledge about possible biological causes is required in order to understand fatigue and the impact on quality of life among Hodgkin's disease survivors.

Hodgkin's disease survivors more fatigued than the general population

PURPOSE

To estimate the level of fatigue and frequency of fatigue cases among Hodgkin's disease survivors (HDS) and compare them with normative data from the general population.

PATIENTS AND METHODS

A cross-sectional follow-up study was done of 557 HDS (age range, 19 to 74 years) treated at the Norwegian Radium Hospital from 1971 to 1991. The sample was approached by mail, and their data were compared with normative data from 2,214 controls (age range, 19 to 74 years) representative of the general Norwegian population. Of the 557 HDS, 459 (82%) responded. The mean age (+/- SD) at the time of study was 44+/-12 years, and the mean observation time was 12+/-6 years. The Fatigue Questionnaire (11 items) measures physical and mental fatigue. Two systems of scoring were used, dichotomized (0, 0, 1, and 1) and Likert (0, 1, 2, and 3). Total fatigue (TF) constitutes the sum of all the Likert scores. Caseness was defined as a total dichotomized score of > or =4 and fatigue that lasted 6 months or longer.

RESULTS

The HDS had significantly higher levels of TF than the controls (14.3 v 12.2) (P < .001). Fatigue among the HDS equaled that of the controls in poorest health. More HDS (61%) than controls (31%) reported fatigue symptoms lasting 6 months or longer (P < .001). Fatigue cases were more frequent among HDS (men, 24%; women, 27%) than among the controls (men, 9%; women, 12%) (P < .001). Disease stage/substage IB/IIB predicted fatigue caseness (P = .03). No significant associations were found between treatment characteristics and fatigue.

CONCLUSION

Hodgkin's disease survivors are considerably more fatigued than the general population and report fatigue of a substantially longer duration.

Reduced health-related quality of life among Hodgkin's disease survivors: a comparative study with general population norms

BACKGROUND

Late complications after curative treatment of Hodgkin's disease are of special relevance because most of the cured are young adults. The aims of the present study were: (1) to compare health-related quality of life (HRQOL) in Hodgkin's disease (HD) survivors with normative data from the general Norwegian population and (2) to examine the relations between disease/treatment characteristics and HRQOL in the HD survivors.

PATIENTS AND METHODS

459 HD survivors aged 19-74 years (mean 44.0, SD 11.8) treated at the Norwegian Radium Hospital 1971-1991 were approached in 1994 and compared to norms from 2214 subjects approached in 1996. The norms are representative of the general Norwegian population. HRQOL was assessed by the Short Form 36 (SF-36), which measures HRQOL in eight separate scales (0 = worst health state, 100 = best health state).

RESULTS

The HD survivors had lower scores than the normal controls on all scales after adjustment for age, gender and educational levels. Statistically significant differences (P < 0.01) were found in general health (10.4), physical functioning (6.1), role limitations (physical, 9.3), physical functioning (3.6) and in vitality (4.7). Patients with disease stage IB-IIB had the lowest scores on all scales. The differences in relation to stage/substage reached statistical significance (P < 0.01) in physical functioning and in role limitations (physical). Time since diagnosis, types of primary treatment or having relapsed were not associated with statistically significant differences in HRQOL.

CONCLUSION

Long-term HD survivors have poorer HRQOL, primarily in physical health, than the general Norwegian population.

Socio-medical situation for long-term survivors of Hodgkin's disease: a survey of 459 patients treated at one institution

We present the socio-medical situation for 459 adult disease-free long-term survivors of Hodgkin's disease (HD) 3-23 years after first line curative treatment. In 1994, 557 patients were sent a self-report questionnaire relating to their social status and 459 patients (82%) replied. Educational or professional plans were changed due to HD in 142 patients (32%). After 6, 12 and 18 months from start of treatment, 52, 82 and 95% of the patients, respectively, had returned to their job or education. The sum of full-time and part-time employment was in men 78% at diagnosis and 85% at follow-up, and in women 57% at diagnosis and 64% at follow-up. Only 2% of men and 3% of women did not have a job at follow-up in 1994. At diagnosis 2% of the patients were permanently disabled versus 19% at follow-up in 1994. Age > 40 years at diagnosis, increased the total score of psychological distress and fatigue and long-term disablement after first line treatment were predictors for permanent disablement. Transient or permanent sexual problems were reported in 16% and 13%, respectively. MVPP (mustine, vinblastine, procarbazine and prednisone) or LVPP (chlorambucil, vinblastine, procarbazine and prednisone) chemotherapy was responsible for most cases of early menopause in women older than 30 years, and of infertility in both men and women. In summary, most long-term HD survivors had adapted well to their socio-medical situation except a high number of permanently disabled patients. By focusing more on factors predisposing for permanent disablement and early treatment for these, more patients may be helped to return to their job.

Translation and performance of the Norwegian SF-36 Health Survey in patients with rheumatoid arthritis. I. Data quality, scaling assumptions, reliability, and construct validity

The SF-36 was translated into Norwegian following the procedures developed by the International Quality of Life Assessment (IQOLA) Project. To test for the appropriateness of the Norwegian Version 1.1 of the SF-36 in patients with rheumatoid arthritis (RA), 1552 RA patients were mailed the form. Psychometric methods used in previous U.S. and Swedish studies were replicated. The response rate was 66%. The sample (mean age 62 years, mean disease duration 13 years) was over-represented by females (79%). Totally, 74% of the questionnaires were complete. Missing value rates per item ranged from 0.4% to 9.0% (mean 4.2%). In the Role-Emotional scale, all three items had missing value rates above average and higher than reported in the U.S. and Swedish studies. Tests of scaling assumptions confirmed the hypothesized structure of the questionnaire, but results were suboptimal in the General Health scale. In all scales the Cronbach's alphas exceeded the 0.70 standard for group comparisons. In the Physical Functioning scale, Cronbach's alpha exceeded the 0.90 standard for individual comparisons. There was good evidence for the construct validity of the questionnaire. Generally, the Norwegian SF-36 version 1.1 distributed to RA patients held the psychometric properties found in other countries and in normal populations. The translations of items in the General Health and Role-Emotional scales were reassessed. Minor deficiencies were detected and changed (SF-36 Norwegian Version 1.2).

Fatigue in the general Norwegian population: normative data and associations

Population norms for interpretation of fatigue measurements have been lacking, and the sociodemographic associations of fatigue are poorly documented. A random sample of 3500 Norwegians, aged 19-80 years, was therefore investigated. A mailed questionnaire included the fatigue questionnaire (11 items) in which the sum score of the responses (each scored 0, 1, 2, 3) is designated as total fatigue (TF). Sixty-seven percent of those receiving the questionnaire responded. Women (TF mean=12.6) were more fatigued than men (TF mean=11.9), and 11.4% reported substantial fatigue lasting 6 months or longer. TF and age were weakly correlated (men: r=0.17; women: r=0.09). No firm associations between fatigue and social variables were found. Disabled and subjects reporting health problems were more fatigued than subjects at work or in good health. Fatigue is highly prevalent in somatic and psychiatric disorders, but is often neglected. This national representative sample provides age- and gender-specific norms that will allow for comparisons and interpretations of fatigue scores in future studies.

[Depression and Down syndrome]

Emotional and behavioural disorders are frequent complications of mental retardation that often go unrecognised or untreated. We describe a 13-year old girl with Down's syndrome and depressive illness who responded well to paroxetin. The importance of organizing comprehensive health provision for children with mental retardation in a way that focuses both psychiatric and physical illness is emphasised.

Compliance in quality of life data: a Norwegian experience

Compliance is of extreme importance in assessing quality of life since lost data never can be retrieved. In order to assess this issue in various studies, a cross-sectional study in cured cancer patients, three prospective trials and a normative study were explored. In the cross-sectional study 82 per cent of the patients completed the questionnaires after one reminder. More females than males answered the questionnaires. The compliance rate varied from 99 per cent to 62 per cent in the prospective studies depending upon time after inclusion. It seems that compliance decreases during follow up, primarily because of disease progression. In one of the prospective studies low compliance rate (approximately 30 per cent) was found in the questionnaire assessing religious issues. In the normative study 68 per cent of the population completed the questionnaire. No gender differences were found, but younger males and elderly women were poor compliers. In conclusion, our data support that most patients complete quality of life questionnaires. It seems that patients with inferior education, reduced physical function and with progressive/terminal disease are low compliers. Introduction of the first quality of life questionnaires to the patients is of great importance. Detailed information about the study should be given and the importance of completing the questionnaires should be underlined.

Disclosing the cancer diagnosis: the patients' experiences

497 Norwegian cancer patients (346 females, 151 males, mean age = 56 years (S.D. = 12)), admitted to a cancer rehabilitation centre, were surveyed on how they were told their diagnosis. Predictors of general satisfaction with the information were assessed. 43% of the subjects were informed by phone, letter or in the corridor/on the round and estimated that the information was presented in less than 5 minutes. Satisfaction with the information was predicted by perceiving the physicians as personally interested (B = 0.528, P < 0.001), comprehending the information (B = 0.245, P < 0.001), being informed in the physicians' offices (B = 0.338, P < 0.001), being informed by physicians at oncological departments (B = 0.278, P = 0.01) and increasing time spent on the disclosure (B = 0.140, P = 0.01). Other aspects of physician-patient communication than the pure presentation of valid information is highly valued by the patients. However, a substantial proportion of physicians present the cancer diagnosis in such a manner that the possibility of engaging in conversation about the diagnosis and the effect upon the patient is very limited. The findings call for remedial attention to the subject and improvement in performance.

Psychological distress after cancer cure: a survey of 459 Hodgkin's disease survivors

To assess the levels of psychological distress and identify predictors of anxiety/depression caseness after cancer cure, a national population of 557 Hodgkin's disease (HD) survivors was surveyed. The respondents [204 women, 255 men, mean age 44 years (SD = 12)] returned a mailed questionnaire including The Hospital Anxiety and Depression Scale (HADS). Disease and treatment variables were based on the hospital records. A total of 27% had caseness scores (anxiety, 14.5%; depression, 4%; anxiety and depression, 8.5%). In a multiple logistic regression analysis, anxiety caseness was predicted by low educational status [OR (odds ratio) = 2.07, 95% CI = 1.02-4.22], observational period 7 years or longer (7-10 years: OR = 3.07, 95% CI = 1.26-7.47), combined irradiation and chemotherapy treatment (OR = 2.77, 95% CI = 1.17-6.54) and psychiatric symptoms before HD (OR = 2.55, 95% CI = 1.40-4.65) or during treatment (OR = 3.51, 95% CI = 2.08-5.90). Depression caseness was predicted by age (OR = 1.03, 95% CI = 1.00-1.06) and psychiatric symptoms before HD (OR = 5.1, 95% CI = 2.55-10.31) Anxiety cases are more prevalent than in the general Norwegian population, and were found to be most common 7-10 years after treatment. The most intensive treatment was associated with increased risk for anxiety caseness. The subjects experienced distress during treatment precedes difficulties in long-term adjustment. Focusing on these predictors during treatment and follow-up controls may improve long-term outcome.

Attitudes toward informing the cancer patient--a survey of Norwegian physicians

To examine Norwegian physicians' attitudes to informing patients of a diagnosis of cancer, a random sample of 1467 were surveyed. The respondents rated their level of agreement to 14 statements, and the responses were analysed by chi-squared statistics. 990 physicians responded (67%). Only 30.5% of the responding physicians had treated more than 10 cancer patients the previous year, which included 7.8% who had treated more than 50. 40.4% had treated none. The great majority (81%) preferred full information of the diagnosis. Physicians with increasing age preferred relatives not being present and gave priority to factual information and informing patients with the same diagnosis identically. Hospital physicians (39.5%) more often preferred other health professionals being present than physicians in private practice (18%) (P < 0.001). Number of cancer patients treated was not associated with attitudes toward the disclosure of information. Norwegian physicians prefer revealing the cancer diagnosis to patients, but have divergent opinions about how to do so. Some of these indicate suboptimal information-giving.
