Long-term health-related quality of life of breast cancer survivors remains impaired compared to the age-matched general population especially in young women. Results from the prospective controlled BREX exercise study.

OBJECTIVE: To investigate long-term health-related quality of life (HRQoL) changes over time in younger compared to older disease-free breast cancer survivors who participated in a prospective randomized exercise trial. METHODS: Survivors (aged 35-68 years) were randomized to a 12-month exercise trial after adjuvant treatment and followed up for ten years. HRQoL was assessed with the generic 15D instrument during follow-up and the younger (baseline age ≤ 50) and older (age >50) survivors' HRQoL was compared to that of the age-matched general female population (n = 892). The analysis included 342 survivors. RESULTS: The decline of HRQoL compared to the population was steeper and recovery slower in the younger survivors (p for interaction < 0.001). The impairment was also larger among the younger survivors (p = 0.027) whose mean HRQoL deteriorated for three years after treatment and started to slowly improve thereafter but still remained below the population level after ten years (difference -0.017, 95% CI: -0.031 to -0.004). The older survivors' mean HRQoL gradually approached the population level during the first five years but also remained below it at ten years (difference -0.019, 95% CI: -0.031 to -0.007). The largest differences were on the dimensions of sleeping and sexual activity, on which both age groups remained below the population level throughout the follow-up. CONCLUSIONS: HRQoL developed differently in younger and older survivors both regarding the most affected dimensions of HRQoL and the timing of the changes during follow-up. HRQoL of both age groups remained below the population level even ten years after treatment.

Health-related Quality of Life of Breast Cancer Survivors Attending an Exercise Intervention Study: A Five-year Follow-up.

BACKGROUND/AIM: As the number of breast cancer survivors is increasing, their long-term health-related quality of life (HRQoL) has become an important issue. The aim of the study is to follow up the HRQoL of breast cancer survivors (BCS) in a prospective randomized exercise intervention study and to compare HRQoL to that of the age-matched general female population. PATIENTS AND METHODS: Following adjuvant treatment, 537 patients aged 35-68 and capable of exercise training were randomized to a 12-month exercise trial. In 182 of those patients, HRQoL was measured by the generic 15D at baseline and followed up for five years. Furthermore, the HRQoL of all BCS answering the 15D at five-year follow-up (n=390) was compared to that of a representative sample of the general population. RESULTS: After five years, the BCS' mean HRQoL demonstrated a statistically and clinically significant impairment compared to that of the general population (difference -0.023, p<0.001). The mean HRQoL of BCS followed up from baseline until five years did not improve significantly (change=0.007, p=0.27), whereas the dimensions of usual activities (0.043, p=0.004), depression (0.038, p=0.007), distress (0.030, p=0.036), and sexual activity (0.057, p=0.009) did. CONCLUSION: The HRQoL of BCS was still impaired five years following treatment.

Costs in Different States of Breast Cancer.

BACKGROUND/AIM: This cross-sectional study estimated direct cancer-related health care, productivity and informal care costs for a six-month period for different states of breast cancer (BC). PATIENTS AND METHODS: A total of 827 BC patients answered a questionnaire enquiring about informal care, work capacity, and demographic factors. Direct health care resource use and productivity costs were obtained from registries. Mutually exclusive groups were formed based on disease state and time from diagnosis: primary treatment (first six months after diagnosis), rehabilitation (>six months after diagnosis), remission (>1.5 years after diagnosis), and metastatic. RESULTS: Mean total costs were: primary treatment €22,876, rehabilitation €3,456, remission €1,728, and metastatic €24,320. Mean direct health care costs were: primary treatment €11,798, rehabilitation €2,398, remission €1,147, and metastatic €13,923. Mean productivity costs varied between 18-39% and indirect costs (productivity and informal care costs) between 31-48% of the total costs. CONCLUSION: Direct medical costs were highest, but indirect costs constituted up to half of the total costs and are essential when estimating the total cost burden, as many patients are of working age.

Cost-effectiveness of interventions based on physical exercise in the treatment of various diseases: a systematic literature review.

OBJECTIVES: The aim of this study was to review studies reporting cost-effectiveness of exercise-based interventions in treatment of various diseases. METHODS: Systematic literature search using several databases. Abstracts initially screened independently by two authors, full-text articles again evaluated by two authors, who decided whether an article should be included. Included were scientifically valid articles describing controlled studies that included an exercise-based intervention in the treatment of an established medical condition, and also reported on the cost-effectiveness of the intervention, or its effect on the utilization of health services. Quality was assessed with an established approach. RESULTS: A total of 914 articles were identified, of them 151 were obtained for closer review. Sixty-five articles describing sixty-one studies were included. Most (82 percent) were randomized trials. Twenty-eight studies dealt with musculoskeletal disorders, fifteen with cardiology, four with rheumatic diseases, four with pulmonary diseases, three with urinary incontinence, and two with vascular disorders. There was one study each in the fields of oncology, chronic fatigue, endocrinology, psychiatry, and neurology. Exercise interventions in musculoskeletal disorders were deemed to be cost-effective in 54 percent, in cardiology in 60 percent, and in rheumatic diseases in 75 percent of the cases. There was some evidence that exercise might be cost-effective in intermittent claudication, breast cancer patients, diabetes, and schizophrenia. CONCLUSIONS: The number of studies assessing cost-effectiveness of exercise interventions in various diseases is still limited. The results show large variation but suggest that some exercise interventions can be cost-effective. Most convincing evidence was found for rehabilitation of cardiac and back pain patients; however, even in these cases, the evidence was partly contradictory.

Use of quality-adjusted life years for the estimation of effectiveness of health care: A systematic literature review.

OBJECTIVES: The objectives of this study were to identify, in a systematic literature review, published studies having used quality-adjusted life years (QALYs) based on actual measurements of patients' health-related quality of life (HRQoL) and to determine which HRQoL instruments have been used to calculate QALYs. Furthermore, the aims were to characterize studies with regard to medical specialty, intervention studied, results obtained, quality, country of origin, QALY gain observed, and interpretation of results regarding cost-effectiveness. METHODS: Systematic searches of the literature were made using the MEDLINE, Embase, CINAHL, SCI, and Cochrane Library electronic databases. Initial screening of identified articles was based on abstracts read independently by two of the authors; full-text articles were again evaluated by two authors, who made the final decision on which articles should be included. RESULTS: The search identified 3,882 articles; 624 were obtained for closer review. Of the reviewed full-text articles, seventy reported QALYs based on actual before-after measurements using a valid HRQoL instrument. The most frequently used instrument was EuroQol HRQoL instrument (EQ-5D, 47.5 percent). Other instruments used were Health Utilities Index (HUI, 8.8 percent), the Rosser-Kind Index (6.3 percent), Quality of Well-Being (QWB, 6.3 percent), Short Form-6D (SF-6D, 5.0 percent), and 15D (2.5 percent). The rest (23.8 percent) used a direct valuation method: Time Trade-Off (10.0 percent), Standard Gamble (5.0 percent), visual analogue scale (5.0 percent), or rating scale (3.8 percent). The most frequently studied medical specialties were orthopedics (15.5 percent), pulmonary diseases (12.7 percent), and cardiology (9.9 percent). Ninety percent of the studies came from four countries: United Kingdom, United States, Canada, the Netherlands. Approximately half of the papers were methodologically high quality randomized trials. Forty-nine percent of the studied interventions were viewed by the authors of the original studies as being cost-effective; only 13 percent of interventions were deemed not to be cost-effective. CONCLUSIONS: Although QALYs gained are considered an important measure of effectiveness of health care, the number of studies in which QALYs are based on actual measurements of patients' HRQoL is still fairly limited.
