The somatic, neurocognitive, and psychiatric side effects of biological response modifiers (BRMs) have been documented in specific patient samples. Although these side effects likely have a predictable impact on patients quality of life (QOL), no instrument currently measures the cumulative effect of the various complaints patients' report. The current study investigated the reliability and validity of the Functional Assessment of Cancer Treatment-Biological Response Modifier (FACT-BRM) scale for measuring QOL in a sample of melanoma patients receiving interferon. Measures of distress, depression, and fatigue were also obtained using standardized, well-validated instruments. Results indicate increased symptom burden, depression, and fatigue, and decreased quality of life over 4 months of IFN therapy. The FACT-BRM demonstrated good psychometrics and sensitivity to change, and thus appears to be a good instrument for measuring QOL in patients receiving BRMs.

Anaemia is an important factor in the fatigue experienced by many patients receiving chemotherapy. A recent large-scale, randomised, placebo-controlled trial has shown that treatment with epoetin alfa raises haemoglobin levels, reduces fatigue and improves overall quality of life (QoL). In order to examine the relationship between anaemia and QoL more closely, we performed multiple regression analyses, adjusting for possible differences in demographic and clinical characteristics between the treatment groups on the trial data derived from FACT, CLAS and SF-36 QoL assessments. This confirmed that QoL is correlated with haemoglobin levels and that treatment with epoetin alfa is associated with a significant improvement in QoL as measured by validated cancer-specific instruments such as FACT and CLAS. However, the sub-group of patients who suffer disease progression during treatment are not predicted to experience an improvement in QoL, confirming the sensitivity of these scales. Race and tumour type were significantly related to changes in QoL scores, but other factors such as age and gender did not show significant effects on QoL.

Anaemia is a common problem for cancer patients and often causes fatigue and reduces quality of life (QoL). Although randomised trials have repeatedly shown that treatment with epoetin alfa raises haemoglobin levels, reduces fatigue and improves overall QoL, such findings may be hard to put into a clinical context and, as a result, cancer-related fatigue remains undertreated. This study gathered data using the FACT-An QoL scale from 1400 people on an internet survey panel. The 1400 were randomly selected and chosen to be representative of the total US population. Survey results were then compared with the findings from a large placebo-controlled study involving 375 anaemic cancer patients. FACT-An showed good psychometric properties in the survey population and was able to distinguish respondents with histories of anaemia and cancer from those without. Comparing the population norm values for FACT-An with the trial data showed that treatment with epoetin alfa led to clinically meaningful improvements in cancer patients' QoL.

The purpose of this review was answer 2 main questions: what is the impact of chronic lymphocytic leukemia (CLL) on the patient's quality of life and how great is the economic burden of this disease on the health care payers and providers. Patients with CLL typically do not receive any treatment soon after the initial diagnosis. Although there is no known cure for CLL yet, when treated, the patients receive aggressive and expensive therapies (eg, chemotherapy or bone marrow transplantation). A rigorous and systematic literature review was performed of English-language articles published in 1990-2002. It was supplemented with additional articles published before 1990 for completeness and additional references to fill the gaps identified in the published medical literature. The literature on the quality of life (QOL) of CLL patients is very limited. We identified only 8 articles, and none of them analyzed the QOL in untreated CLL patients. Because CLL is a disease affecting adults, especially the elderly, all 8 studies measured the QOL in the adult population. QOL difficulties include fear of death and disability, problems gaining employment or health insurance, and fatigue. No specific leukemia or CLL instruments but general QOL instruments (eg, I-HRQL) were identified and some cancer-specific ones (eg, EORTC QLQ-C30, FACT-G, FACT Anemia, FACT-Fatigue). Interestingly, a FACT-Bone Marrow Transplant instrument exists, although we found no study on CLL that used it. Even the literature on the economic burden of CLL is very limited. We identified 13 studies on the cost of CLL: Most of them were cost-identification or cost-comparison studies, and 5 dealt with the cost-effectiveness of medical interventions to treat CLL. Cost drivers identified for CLL were the chemotherapy costs, intravenous immunoglobulin costs, transplantation costs, and costs associated with the differential staining cytotoxicity assay. We identified very few articles on the QOL of CLL patients and therefore cannot draw strong conclusions about the key QOL predictors. Nevertheless, patients with anemia were found to have a better QOL if they had higher hemoglobin counts and good response to erythropoietin treatment. The articles published seem to demonstrate that the older the age of the patient was, the poorer the QOL. The main cost drivers identified for CLL were related to the treatment chosen (eg, chemotherapy, bone marrow transplantation). There are hints that higher costs often result from the delivery of non-optimal therapy that leads to adverse events, infections, and drug resistance. In summary, the impact of this disease on the health care budget of the different health care providers and payers as well as on the patient's QOL is substantially unknown, calling for appropriate economic and QOL studies.

This study prospectively evaluated quality of life (QOL) in localized prostate cancer patients undergoing radiotherapy, and it examined the relationships between QOL, depression, fatigue, and sleep disturbance. Instruments that were used are Functional Assessment of Cancer Therapy for Prostate (FACT-P), Beck Depression Inventory (BDI), Piper Fatigue Scale (PFS), and Epworth Sleepiness Scale (ESS). We evaluated patients at preradiotherapy (PRT), midway radiotherapy (MRT), completion of radiotherapy (CRT), follow-up radiotherapy (4 to 8 wk) (FRT), and long-term follow-up radiotherapy (FRT2) (12 mo or more). Forty participants with a mean age of 67.8 yr were studied. Duration of radiotherapy was 7-8 wk. Mean long-term follow-up period post-CRT was 16.2 mo (range 12- 24 mo). All patients had clinical T1c to T2b prostate cancer. Prostate Cancer Specific (PCS) and Physical Well-Being (PWB) subscales of FACT-P, scores at MRT and CRT were significantly lower than at PRT. At FRT2, PWB scores declined further, while PCS scores increased. PFS median scores were significantly higher at CRT and at FRT2 as compared with PRT. Patients scoring higher on PFS were more likely to report a poorer QOL and PWB as measured with FACT-P questionnaire. No significant changes were noted in the BDI and ESS scores during the study periods. The PWB declined during and at CRT and worsened at FRT2. Decline in PCS subscale scores during and at CRT reflects worsening of urinary symptoms and appearance of bowel problems. The scores improved at long-term follow-up. A relationship was found to exist between physical well-being and fatigue.

In a large, 16-week, prospective study of 2,964 anemic patients with various cancers undergoing chemotherapy, once-weekly subcutaneous administration of 40,000 U of epoetin alfa,with potential escalation to 60,000 U, increased hemoglobin (Hgb) levels, decreased transfusion requirements, and improved quality of life (QOL) as assessed using the Linear Analog Scale Assessment (LASA) for energy, activity, and overall QOL and the Functional Assessment in Cancer Therapy-Anemia (FACT-An) QOL instrument. A retrospective subset analysis conducted in 244 colorectal cancer patients enrolled in the study showed statistically significant improvements from baseline to final readings in LASA energy, activity, and overall QOL and FACT-An Anemia Symptoms and Fatigue subscale scores (P < 0.02). Moreover, patients who achieved larger improvements in Hgb levels also demonstrated greater percentage improvements in QOL over baseline measurements. Mean Hgb levels increased by 1.2 g/dL after 4 weeks of treatment and by 1.6 g/dL by study end, independent of red blood cell transfusion within 28 days prior to the Hgb assessment. Hematopoietic response (Hgb level > or = 12 g/dL and/or increase in Hgb level > or = 2 g/dL, independent of transfusion) was observed in 61% of patients (139/229). Additionally, the proportion of patients receiving transfusions decreased from 17% at baseline to 4% during the final month of therapy. Epoetin alfa was well tolerated, with no evidence of unexpected adverse events. Except for significantly higher QOL scores at baseline, results for the cohort of colorectal cancer patients were similar to those for patients with other cancer types in the main study population.

Fatigue is common in cancer patients treated with chemotherapy, and it has detrimental effects on their quality of life. Chemotherapy-induced anemia, however, is often under-recognized and under-treated. There is a clear association between hemoglobin (Hgb) levels and fatigue, with fatigue being greater in patients with lower Hgb levels. Managing fatigue requires that its causes be determined and corrected, and it is important that patients report their fatigue. Patients, however, are unlikely to mention such adverse events unless they are asked about them. In addition, busy practitioners generally have very little time to discuss anemia-related fatigue with their patients. Many studies have used the validated quality-of-life instrument Functional Assessment of Cancer Therapy-Fatigue (FACT-F) to assess fatigue and quality of life in patients treated with chemotherapy; these studies have shown a relationship between chemotherapy-induced anemia, fatigue, and quality of life. Studies of erythropoiesis-stimulating proteins to treat chemotherapy-induced anemia have shown increases in patients' hemoglobin levels, improvement in their FACT-F and FACT-General scores, and improvements in their quality of life.

The current study evaluated a newly developed self-report measure of cognitive complaints with cancer patients, the Functional Assessment of Cancer Therapy Cognitive Scale (FACT-Cog). Six or 12 months following hematopoietic stem cell transplantation, participants completed a psychosocial assessment that included the FACT-Cog and a neuropsychological assessment. Using a criterion of two or more times a week, an average of 12 of a total of 50 items were endorsed as complaints on the FACT-Cog. FACT-Cog total, domain, and subscale scores were significantly correlated with measures of depression, fatigue, anxiety, and physical and mental well-being. FACT-Cog scores, with the exception of one subscale, Other People Noticed Deficits, were not significantly correlated with cognitive performance. In general, the FACT-Cog and a commonly used measure of cognitive complaints (European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire-C30 Cognitive Functioning Scale) demonstrated similar psychometric properties. However, the FACT-Cog assesses broader aspects of cognitive complaints, thereby providing greater information about the types of cognitive complaints patients are experiencing.

Fatigue is an extremely common side effect experienced during cancer treatment and recovery. Limited research has investigated strategies stemming from complementary and alternative medicine to reduce cancer-related fatigue. This research examined the effects of Reiki, a type of energy touch therapy, on fatigue, pain, anxiety, and overall quality of life. This study was a counterbalanced crossover trial of 2 conditions: (1) in the Reiki condition, participants received Reiki for 5 consecutive daily sessions, followed by a 1-week washout monitoring period of no treatments, then 2 additional Reiki sessions, and finally 2 weeks of no treatments, and (2) in the rest condition, participants rested for approximately 1 hour each day for 5 consecutive days, followed by a 1-week washout monitoring period of no scheduled resting and an additional week of no treatments. In both conditions, participants completed questionnaires investigating cancer-related fatigue (Functional Assessment of Cancer Therapy Fatigue subscale [FACT-F]) and overall quality of life (Functional Assessment of Cancer Therapy, General Version [FACT-G]) before and after all Reiki or resting sessions. They also completed a visual analog scale (Edmonton Symptom Assessment System [ESAS]) assessing daily tiredness, pain, and anxiety before and after each session of Reiki or rest. Sixteen patients (13 women) participated in the trial: 8 were randomized to each order of conditions (Reiki then rest; rest then Reiki). They were screened for fatigue on the ESAS tiredness item, and those scoring greater than 3 on the 0 to 10 scale were eligible for the study. They were diagnosed with a variety of cancers, most commonly colorectal (62.5%) cancer, and had a median age of 59 years. Fatigue on the FACT-F decreased within the Reiki condition (P=.05) over the course of all 7 treatments. In addition, participants in the Reiki condition experienced significant improvements in quality of life (FACT-G) compared to those in the resting condition (P <.05). On daily assessments (ESAS) in the Reiki condition, presession 1 versus postsession 5 scores indicated significant decreases in tiredness (P <.001), pain (P <.005), and anxiety (P<.01), which were not seen in the resting condition. Future research should further investigate the impact of Reiki using more highly controlled designs that include a sham Reiki condition and larger sample sizes.
