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.

Late medical complications and fatigue in Hodgkin's disease survivors.

PURPOSE: Long-term medical complications, such as cardiac, pulmonary, and thyroid dysfunction, are frequent among Hodgkin's disease survivors (HDSs). Chronic fatigue is also highly prevalent among HDSs. Few studies have explored possible etiologic explanations for fatigue. The aim of this study was to explore whether late cardiac, pulmonary, and thyroid complications after curative treatment for Hodgkin's disease (HD) may explain the high level of fatigue among HDSs. PATIENTS AND METHODS: Four-hundred fifty-nine patients treated for HD at the Norwegian Radium Hospital from 1971 to 1991 were included in a cross-sectional, follow-up study of subjective health status. Fatigue (physical [PF] and mental), was measured by the Fatigue Questionnaire. A subcohort of the HDSs (116 patients) treated from 1980 to 1988 were included in a separate study in which long-term cardiac, pulmonary, and thyroid complications were assessed. All patients had received radiotherapy, and 63 patients had received additional chemotherapy. The present study comprised 92 patients (mean age, 37 years; range, 23 to 56 years) who participated in both studies. RESULTS: HDSs with pulmonary dysfunction were more fatigued than HDSs with normal pulmonary function (PF 10.9 v 8.9; P <.05). Gas transfer impairment was the most prevalent pulmonary dysfunction, and three times as many patients with gas transfer impairment reported chronic fatigue (duration, 6 months or longer), compared with patients without pulmonary dysfunction (48% v 17%, P <.01). No associations were found between cardiac sequelae or hypothyroidism and fatigue. CONCLUSION: Pulmonary dysfunction is associated with fatigue in HDSs. Cardiac sequelae was not associated with fatigue in HDSs. We question the absence of an association between thyroid complications and fatigue.

[Palliative sedation to dying patients in Norway].

BACKGROUND: In May 2000, the Norwegian Medical Association appointed a working group to propose guidelines for the practice of palliative sedation to dying patients (terminal sedation). The present study is part of this work. The aim of the study was to register to what extent this form of palliation is used in Norwegian hospitals, on what indications, how decisions are reached, and whether the treatment is considered necessary. The definition of palliative sedation given was: induction and maintenance of sleep for the relief of pain or other types of suffering in a patient close to death. The intention is exclusively to relieve intractable pain, not to shorten the patient's life. MATERIAL AND METHODS: An anonymous questionnaire was sent to 364 Norwegian hospital departments that might have experience with palliative sedation. Results are reported partly as free text comments and partly as frequencies of predetermined response alternatives. RESULTS: 58% of the questionnaires were returned. 22% of the respondents had given palliative sedation to a dying patient during the last 12 months, and more than half of the physicians found this intervention sometimes necessary. Pain was the most frequent indication; none of the respondents claimed to haven given sedation exclusively based on depression/anxiety. Lack of resources still seems to be an obstacle to optimal palliative care in Norway. CONCLUSION: Though it has some methodological weaknesses, this study confirms the need for national guidelines.

Factors affecting grief reactions in close family members to individuals who have died of cancer.

This longitudinal study examined factors related to grief reactions in a systematic and standardized way in 183 close family members to individuals who died of cancer. Grief reactions were measured using the Texas Revised Inventory of Grief (TRIG). A repeated measures MANOVA was used to test and compare the grief reactions of the bereaved for one year after the loss. The female respondents showed stronger grief reactions than the male respondents. The grief reactions increased with age, and those who had lost a younger family member experienced stronger grief reactions than those who had lost an older family member. The relationship to the deceased, the duration of the disease, place of death, aspects of social support such as children living at home, and employment were not related to the grief reactions in the bereaved respondents when controlling for the former factors.

Palliative care research.

Most of the research in palliative medicine is of a descriptive nature. Clinical practice is based upon clinical experience rather than upon research. The level of appropriate research reduces the chance for improvement of palliative care. Ethical and methodological obstacles seem to be prominent in palliative care research. The Declaration of Helsinki is generally accepted as an ethical code of practice for clinical research and it also applies to palliative care. In order to obtain reliable data, standardisation of data collection is needed. Improvement of quality of life is the primary endpoint in most studies in palliative care. The existing validated quality of life instruments such as the European Organization for Research and Treatment of Cancer (EORTC) quality of life (QLQ)-C30 can be used until the patient is too sick to complete the questionnaire. New approaches are needed and must be developed for the dying patients. Palliative care research needs proper funding; specific programmes supporting research on a European level are needed. The European Association for Palliative Care (EAPC) is capable of conducting and coordinating collaborative research in palliative care on a European level.

A prospective study of quality of life in head and neck cancer patients. Part I: at diagnosis.

PURPOSE: A Swedish and Norwegian study was designed to examine health-related quality of life (HQL) in patients with head and neck cancer (head and neck) at diagnosis and during treatment and rehabilitation. The overall aim was to examine the impact on HQL at diagnosis depending on tumor location, stage, sex, and age (part I) and to describe HQL longitudinally and determine for which patients and during which period HQL deteriorated most (part II). This article presents the results at diagnosis. METHOD: Patients with head and neck cancer at five hospitals in Sweden and Norway were consecutively requested to participate. They were asked to answer the EORTC QLQ-C30 and QLQ-H&N35 (the European Organization for Research and Treatment of Cancer, Core 30 questionnaire and head and neck cancer module) repeatedly during 1 year. A total of 357 patients (mean age, 63 y; 72% males) were included. RESULTS: Patients with different tumor locations all had their special problems at diagnosis, for example, those with tumors in the larynx with communication, those with oral tumors with pain, and those with pharyngeal tumors with nutrition and pain. The patients with hypopharyngeal cancer reported the worst HQL. Stage appeared to have the strongest impact on HQL. Patients with a more advanced tumor stage reported significantly worse HQL scores for 24 of 32 variables reflecting functioning or problems. The females scored worse than the males for some areas, in particular, emotional functioning. The older patients scored significantly better for emotional and social functioning than patients <65 years but worse for physical functioning and various symptoms. The traditional way of grouping the tumor locations into oral, pharyngeal, laryngeal, and "other" tumors (salivary gland, sinus and nose, and unknown primary) was tested from a HQL point of view and found to be consistent. CONCLUSIONS: The chosen questionnaires differentiated between different sites of head and neck cancer at diagnosis. Tumor stage had the most powerful impact on HQL score.

A prospective study of quality of life in head and neck cancer patients. Part II: Longitudinal data.

OBJECTIVES: To evaluate the health-related quality of life (HRQL) of patients with head and neck cancer during and after treatment with radiotherapy, surgery, and chemotherapy. STUDY DESIGN: Prospective, descriptive study. METHODS: All new patients in four institutions in Norway and Sweden were asked to participate. Health-related quality of life was assessed at baseline and at 1, 2, 3, 6, and 12 months after start of treatment by means of the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire and the EORTC head and neck cancer-specific questionnaire. Baseline results are described elsewhere; longitudinal results are presented in the current article. Three hundred fifty-seven patients with cancer in the oral cavity, pharynx, larynx, nose, sinuses, and salivary glands and neck node metastases from unknown primaries filled in the questionnaires at baseline. RESULTS: Seventy-eight percent of the patients who were alive after 12 months filled in all questionnaires (218/280). The general trend was that HRQL deteriorated significantly during treatment, followed by a slow recovery until the 12-month follow-up with few exceptions (senses, dry mouth, and sexuality). Patients who later died reported worse HRQL at each assessment point compared with patients who filled in all six questionnaires, whereas those who dropped out of the study for other reasons were quite similar to patients who filled in all questionnaires. The patients with pharyngeal cancer in general reported worse HRQL compared with the other groups and did not reach pretreatment values in several domains. Stage was also an important factor for HRQL in patients with head and neck cancer. CONCLUSION: Detailed knowledge about the differences between groups and changes over time may aid us in the communication with patients and in the design of intervention studies focusing on improvement of the support and rehabilitation of patients with head and neck cancer.

The first year of grief and bereavement in close family members to individuals who have died of cancer.

Using a systematic and standardized method this longitudinal study examines changes in grief reactions in a sample of close family members (n = 183) to individuals who had died of cancer. The respondents were followed for 1 year after the loss. The study sample originated from a cluster randomized trial evaluating comprehensive palliative care (intervention) against conventional care (control). Hence, we also compared grief reactions among close family members to the patients in the intervention and control groups. Overall, the family members' grief reactions, as measured by the second part of the Texas Revised Inventory of Grief (TRIG), showed a significant decline over the period studied. However, we found no significant differences in grief reactions between the family members to the intervention and control patients at any point in time, and the pattern of change did not differ significantly for the two groups.

[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.

A palliative-care intervention and death at home: a cluster randomised trial.

BACKGROUND: The Palliative Medicine Unit at University Hospital of Trondheim, Norway, started an intervention programme that aims to enable patients to spend more time at home and die there if they prefer. Close cooperation was needed with the community health-care professionals, who acted as the principal formal caregivers, and a multidisciplinary consultant team coordinated the care. We did a cluster randomised trial to assess the intervention's effectiveness compared with conventional care METHODS: Community health-care districts in and around Trondheim, Norway, were defined as the clusters to be randomised. We enrolled 434 patients (235 assigned intervention and 199 conventional care [controls]) in these districts who had incurable malignant disease and an expected survival of 2-9 months. Main outcomes were place of death and time spent in institutions in the last month of life. FINDINGS: 395 patients died. Of these, more intervention patients than controls died at home (54 [25%] vs 26 [15%], p<0.05). The time spent at home was not significantly increased, although intervention patients spent a smaller proportion of time in nursing homes in the last month of life than did controls (7.2 vs 14.6%, p<0.05). Hospital use was similar in the two groups. INTERPRETATION: The palliative-care intervention enabled more patients to die at home. More resources for care in the home (palliative care training and staff) and an increased focus on use of nursing homes would be necessary, however, to increase time at home and reduce hospital admissions.

[Is terminal sedation active euthanasia?].

In order to be able to discuss the issue of whether or not terminal sedation is, or may be conceived of as, a form of help in dying, one needs to be very clear as to the meaning of the terms "help in dying" and "terminal sedation". In this article, we suggest what we take to be detailed and precise definitions of the two forms of voluntary help in dying--euthanasia and physician-assisted suicide. Our definitions (interpretations) basically draw on the Dutch experience and understanding. The Dutch approach implies that acts of abstention, i.e., withholding and withdrawing treatment, and pain and symptom treatment with possible life-shortening effect, including terminal sedation, are to be considered "normal medical practice". Furthermore, death is seen by almost all parties as having natural causes in all of these acts. We also suggest that "palliative sedation" should substitute the expression "terminal sedation". Furthermore, we discuss on what grounds this treatment strategy may be induced, including a presentation of criteria and guidelines that must be met; the issue of documentation of the strategy; palliative sedation in the light of the ethical principle of double effect; and in what way euthanasia could be concealed as palliative sedation. In closing, we comment briefly on the phenomenon of large differences between published cohorts with regard to the frequency of use of palliative sedation. This treatment strategy is open to be challenged both clinically and ethically, and all parties would benefit from a continuous debate over the legitimacy of, and the clinical need for, palliative sedation.

Start of oral morphine to cancer patients: effective serum morphine concentrations and contribution from morphine-6-glucuronide to the analgesia produced by morphine.

OBJECTIVE: To investigate the serum concentrations of morphine, morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G) and the relationships between serum concentrations and clinical effects associated with start of morphine treatment in cancer patients. METHODS: Forty patients with malignant disease and intolerable pain on weak opioids (codeine/dextropropoxyphen) were included. After a wash-out period, titration with immediate-release (IR) morphine was started. When a stable dose was achieved, the morphine treatment was changed to slow-release (SR) morphine in equivalent daily dosages. Clinical data and serum concentrations of morphine, M3G and M6G were obtained at the end of the IR and SR morphine treatment periods. RESULTS: The mean trough serum morphine concentration associated with pain relief was 66 nmol/l. The corresponding mean concentrations of M6G and M3G were 257 nmol/l and 1943 nmol/l, respectively. Morphine serum trough concentrations showed a 33-fold variation. Seventy percent of the variation was predicted in a model including age, daily morphine dose and M6G/morphine ratio as independent variables. No associations were observed between side effects and serum concentrations of morphine and its metabolites. CONCLUSION: In this study, a mean serum trough morphine concentration of 66 nmol/l was associated with satisfactory pain relief when disease progression required an increase in intensity of pain therapy from step II to step III in the World Health Organization pain ladder. An increased ratio of M6G to morphine serum concentrations predicted lower effective serum morphine concentrations at the time of satisfactory pain relief. This observation supports that M6G contributes to the pain control produced by oral morphine in patients with pain caused by malignant disease.

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.

Effects on cancer patients' health-related quality of life after the start of morphine therapy.

To investigate the effects of morphine on cancer patients' health-related quality of life (HRQL), we prospectively studied 40 cancer patients with moderate or severe pain despite treatment with "weak" opioids. The patients were titrated to pain relief using immediate-release (IR) morphine and then switched to slow-release (SR) morphine in the same daily dosages. HRQL was measured by the European Organization for Research and Treatment of Cancer core quality-of-life questionnaire (EORTC QLQ-C30) before the start of morphine (baseline), after stabilization with IR-morphine, and 3 days after start of SR-morphine. The mean titrated daily morphine dosage was 97 mg (range, 60-180). The EORTC QLQ-C30 global health score increased after IR morphine titration (baseline score 40, IR morphine period score 49), but a significant difference from baseline did not persist during the SR morphine period (score 44). The other functional HRQL scores showed no significant fluctuations. After start of IR morphine, two of the HRQL symptom scores increased, nausea/vomiting and constipation, but these changes also did not persist during the SR morphine period. Intensity of pain was associated with a lower level of function and higher intensity of symptoms, but only with relatively small (not higher than 0.44) correlation coefficients. Compared to normative data from the general population, physical function, role function, social function, and global health were impaired in the study patients. The patients also suffered more fatigue, pain, nausea/vomiting, appetite loss, and constipation. In conclusion, in cancer patients with reduced HRQL, the start of morphine therapy had no major influence on aspects of HRQL other than pain.

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.
