Patients with advanced cancer frequently express positive attitudes and can be unduly optimistic about the potential benefits of treatment. In order to evaluate an illusory domain in the context of advanced cancer, we developed a scale of will to live and characterized the beliefs that patients held about the curability of their cancer, and how committed they were to using alternative treatments. A measure of quality of life was used as the dependent variable in order to assess the association between these attributes. After a preliminary exploration confirmed the presence of an illusory domain, these concepts were prospectively tested in 149 ambulant patients with advanced cancer who attended for palliative systemic treatment, radiation treatment or supportive care. The scale of global quality of life was reliable (Cronbach's alpha coefficient 0.72). The distribution of the scores of will to live was skewed, with no respondent scoring poorly, and the scale was reliable (Cronbach's alpha coefficient 0.82). The scale of belief in curability showed diverse beliefs. In some cases, there was a discrepancy between respondents' beliefs in curability and what they believed to be the report by their doctors. There was also an association between a committed use of alternative treatments and a belief in the curability of the cancer (p

The purpose of this study was to compare the physical, psychological and social dimensions associated with quality-of-life outcomes over the last year of life, between advanced cancer users and nonusers of complementary and alternative medicine. One hundred and eleven patients were identified through Queensland Cancer Registry records, and followed up every four to six weeks until close to death using standardized protocols. Outcome measures were symptom burden, psychological distress, subjective wellbeing, satisfaction with conventional medicine and need for control over treatment decisions. At the initial interview, 36 (32%) participants had used complementary/ alternative medicine the previous week; mainly vitamins, minerals and tonics and herbal remedies. Among all participants, 53 (48%) used at least one form of complementary/ alternative medicine over the study period. Only six (11%) visited alternative practitioners on a regular basis. Overall, complementary/ alternative medicine users reported higher levels of anxiety and pain, less satisfaction with conventional medicine and lower need for control over treatment decisions compared with nonusers. These differences tend to change as death approaches. A more rigorous assessment of complementary/ alternative medicine use, psychological distress, pain and subjective wellbeing among patients with advanced cancer is needed in the clinical setting.

Background and Objectives: This pilot project assessed the acceptability of a mixed-type, moderate-intensity exercise programme following breast cancer treatment, and the impact on presence of lymphoedema, fitness, body composition, fatigue, mood and quality of life. Methods: Ten women completed the programme and measures of fitness (submaximal ergometer test), body composition (bio-electrical impedance), lympoedema (bio-electrical impedance and arm circumferences), fatigue (revised Piper Fatigue Scale), mood (Hospital Anxiety and Depression Scale), quality of life (FACT-B) and general well-being, at baseline, completion of the programme, and 6-week and 3-month follow-up. Results: Participation in the programme caused no adverse effect on the presence of lymphoedema. There was a trend towards reduction in fatigue and improved quality of life across the testing phases. Women rated the programme extremely favourably, citing benefits of the support of other women, trained guidance, and the opportunity to experience different types of exercise. Conclusions: A mixed-type, moderate-intensity exercise program in a group format is acceptable to women following breast cancer treatment, with the potential to reduce fatigue and improve quality of life, without exacerbating or precipitating lymphoedema. This pilot work needs to be confirmed in larger randomised studies. (C) 2004 Wiley-Liss, Inc.

Objective: To assess the reliability and validity of a brief measure of quality of life recently developed by the World Health Organization, the WHOQOL-BREF, and to examine its association with a variety of clinical and sociodemographic factors in older depressed patients. Design: Cross-sectional study. Methods: Older depressed patients (N=41) underwent diagnostic assessment using the Composite International Diagnostic Interview (CIDI) and were independently assessed on a variety of measures including the WHOQOL-BREF (a 26-item self-report questionnaire generating four domain scores), Hamilton Depression Rating Scale (HAM-D); Geriatric Depression Scale (GDS); Mini-mental State Examination (MMSE); Modified Barthel Index (MBI); Instrumental activities of daily living (IADL), and measures of physical health status and social relationships. Estimates of inter-rater and test-retest reliability, and concurrent validity were made. Results: 39 subjects completed the study. The majority of subjects (94.9%) received a diagnosis of DSM-IV Major Depressive Disorder. Levels of comorbidity were high. Three of the four domains of the WHOQOL-BREF (Physical, Psychological and Environment domains) demonstrated satisfactory reliability and validity. However, the Social Relationships domain exhibited poor validity. Quality of life scores were strongly correlated with severity of depression, number of self-reported physical symptoms and self-assessed general health status. There was no relationship between diagnostic comorbidity and quality of life scores. Conclusions: The WHOQOL-BREF was successfully administered to older depressed patients although the concurrent validity of one of its four domains was poor. Quality of life scores were strongly correlated with severity of depression, raising the issue of measurement redundancy.

The purpose of this investigation was to evaluate the impact of undertaking peripheral blood stem cell transplantation (PBST) on quality of life (QoL), and to determine the effect of participating in a mixed-type, moderate-intensity exercise program on QoL. It was also an objective to determine the relationship between peak aerobic capacity and QoL in PBST patients. QoL was assessed via the CARES questionnaire and peak aerobic capacity by a maximal graded treadmill test, pretransplant (PI), post transplant (PII) and following a 12-week intervention period (PIII). At PII, 12 patients were divided equally into a control or exercise intervention group. Undergoing a PBST was associated with a statistically but not clinically significant decline in QoL (P < 0.05). Following the intervention, exercising patients demonstrated an improved QoL when compared with pretransplant ratings (P < 0.01) and nonexercising transplant patients (P < 0.05). Moreover, peak aerobic capacity and QoL were correlated (P < 0.05). The findings demonstrated that exercise participation following oncology treatment is associated with a reduction in the number and severity of endorsed problems, which in turn leads to improvements in global, physical and psychosocial QoL. Furthermore, a relationship between fitness and QoL exists, with those experiencing higher levels of fitness also demonstrating higher QoL.

Background and aim: Obesity is a risk factor for progression of fibrosis in chronic liver diseases such as non-alcoholic fatty liver disease and hepatitis C. The aim of this study was to investigate the longer term effect of weight loss on liver biochemistry, serum insulin levels, and quality of life in overweight patients with liver disease and the effect of subsequent weight maintenance or regain. Patients: Thirty one patients completed a 15 month diet and exercise intervention. Results: On completion of the intervention, 21 patients (68%) had achieved and maintained weight loss with a mean reduction of 9.4 (4.0)% body weight. Improvements in serum alanine aminotransferase (ALT) levels were correlated with the amount of weight loss (r=0.35, p=0.04). In patients who maintained weight loss, mean ALT levels at 15 months remained significantly lower than values at enrolment (p=0.004), while in regainers (n=10), mean ALT levels at 15 months were no different to values at enrolment (p=0.79). Improvements in fasting serum insulin levels were also correlated with weight loss (r=0.46, p=0.04), and subsequent weight maintenance sustained this improvement. Quality of life was significantly improved after weight loss. Weight maintainers sustained recommended levels of physical activity and had higher fasting insulin levels (p=0.03) at enrolment than weight regainers. Conclusion: In summary, these findings demonstrate that maintenance of weight loss and exercise in overweight patients with liver disease results in a sustained improvement in liver enzymes, serum insulin levels, and quality of life. Treatment of overweight patients should form an important component of the management of those with chronic liver disease.

Background/Aims: Peginterferon alfa-2a plus ribavirin improves sustained virological responses compared with interferon alfa-2b and ribavirin, or peginterferon alfa-2a alone in chronic hepatitis C. We examined the impact of these treatments on health related quality of life (HRQOL). Methods: Patients (n = 1121) were randomized to peginterferon alfa-2a weekly plus ribavirin or placebo, or interferon alfa-2b thrice weekly plus ribavirin. HRQOL was assessed with the SF-36 Health Survey and Fatigue Severity Scale (FSS). Results: Patients receiving peginterferon alfa-2a plus ribavirin reported better HRQOL than those receiving interferon alfa-2b plus ribavirin. These differences were statistically significant for three SF-36 domains and both FSS scores (p < = 0.05). Patients receiving peginterferon alfa-2a plus placebo had the least impairment; adding ribavirin significantly decreased five domains of the SF-36 and both FSS scores. Sustained virological response was associated with improvement at follow-up on all SF-36 and FSS scores. Conclusions: The effects of combination therapy on HRQOL and fatigue are less with peginterferon alfa-2a plus ribavirin than interferon alfa-2b plus ribavirin. Each medication in combination therapy with interferon and ribavirin, affects patients' quality of life differently. Understanding the relationship of specific therapeutic options to HRQOL may help physicians minimize the impact of therapy on HRQOL. (C) 2004 European Association for the Study of the Liver.
