Cognitive behavioral therapy or graded exercise therapy compared with usual care for severe fatigue in patients with advanced cancer during treatment: a randomized controlled trial.

BACKGROUND: Cancer-related fatigue remains a prevalent and burdensome symptom experienced by patients with advanced cancer. Our aim was to assess the effects of cognitive behavioral therapy (CBT) or graded exercise therapy (GET) on fatigue in patients with advanced cancer during treatment with palliative intent. PATIENTS AND METHODS: A randomized controlled trial was conducted from 1 January 2013 to 1 September 2017. Adult patients with locally advanced or metastatic cancer who reported severe fatigue during treatment [Checklist Individual Strength, subscale fatigue severity (CIS-fatigue) ≥35] were accrued across nine centers in The Netherlands. Patients were randomly assigned to either 12 weeks of CBT or GET, or usual care (1 : 1: 1, computer-generated sequence). Primary outcome was CIS-fatigue at 14 weeks. Secondary outcomes included fatigue measured with the European Organisation for Research and Treatment of Cancer-Quality of Life Questionnaire (EORTC-QLQ-C30), quality of life, emotional functioning, physical functioning, and functional impairments at baseline, 14, 18, and 26 weeks. RESULTS: Among 134 participants randomized, the mean age was 63 (standard deviation 9) years and 77 (57%) were women. Common diagnoses included: breast (41%), colorectal (28%), and prostate cancer (17%). A total of 126 participants completed assessment at 14 weeks. Compared with usual care, CBT significantly reduced fatigue [difference -7.2, 97.5% confidence interval (CI) -12.7 to -1.7; P = 0.003, d = 0.7], whereas GET did not (-4.7, 97.5% CI -10.2 to 0.9; P = 0.057, d = 0.4). CBT significantly reduced EORTC-QLQ-C30 fatigue (-13.1, 95% CI -22.1 to -4.0; P = 0.005) and improved quality of life (10.2, 95% CI 2.4 to 17.9; P = 0.011) and physical functioning (7.1, 95% CI 0.5 to 13.7; P = 0.036) compared with usual care. Improvement in emotional functioning and decrease in functional impairments failed to reach significance. GET did not improve secondary outcomes compared with usual care. CONCLUSIONS: Among advanced cancer patients with severe fatigue during treatment, a CBT intervention was more effective than usual care for reducing fatigue. Following GET, patients reported lower fatigue, but results were not significant, probably due to a smaller sample size and lower adherence than anticipated.

Screening with the double surprise question to predict deterioration and death: an explorative study.

BACKGROUND: Early identification of palliative patients is challenging. The Surprise Question (SQ1; Would I be surprised if this patient were to die within 12 months?) is widely used to identify palliative patients. However, its predictive value is low. Therefore, we added a second question (SQ2) to SQ1: 'Would I be surprised if this patient is still alive after 12 months?' We studied the accuracy of this double surprise question (DSQ) in a general practice. METHODS: We performed a prospective cohort study with retrospective medical record review in a general practice in the eastern part of the Netherlands. Two general practitioners (GPs) answered both questions for all 292 patients aged ≥75 years (mean age 84 years). Primary outcome was 1-year death, secondary outcomes were aspects of palliative care. RESULTS: SQ1 was answered with 'no' for 161/292 patients. Of these, SQ2 was answered with 'yes' in 22 patients. Within 12 months 26 patients died, of whom 24 had been identified with SQ1 (sensitivity: 92%, specificity: 49%). Ten of them were also identified with SQ2 (sensitivity: 42%, specificity: 91%). The latter group had more contacts with their GP and more palliative care aspects were discussed. CONCLUSIONS: The DSQ appears a feasible and easy applicable screening tool in general practice. It is highly effective in predicting patients in high need for palliative care and using it helps to discriminate between patients with different life expectancies and palliative care needs. Further research is necessary to confirm the findings of this study.

The relationship of fatigue in breast cancer survivors with quality of life and factors to address in psychological interventions: A systematic review.

Severe fatigue occurs in one in four breast cancer survivors (BCS). Quality of life (QOL) and psychological factors are important in fatigue-oriented interventions for BCS, but an up-to-date overview is lacking. The aims of this review were to (i) provide a comprehensive overview of the relationship of fatigue with QOL and factors that can be addressed in psychological interventions for fatigue in BCS and (ii) determine the strength of evidence for these relationships. A systematic literature search was conducted to find studies on fatigue in BCS who had completed curative breast cancer treatment. Fatigue-related factors of 57 eligible studies were extracted and the level of evidence was determined. Factors regarding QOL (ie, general QOL, functioning, work ability, and mental health) had a negative relationship with fatigue (moderate to strong evidence). Target factors for psychological interventions were divided into the subcategories emotional problems, sleep disturbances, physical activity, pain, coping with cancer, dysfunctional cognitions, and social support. Moderate to strong evidence appeared for a relationship of fatigue with depressive symptoms, anxiety, distress, sleep disturbances, lower physical activity levels, pain, difficulties with coping with cancer, and catastrophizing about symptoms. These factors are points of attention for existing and future psychological interventions for fatigue in BCS.

Gebruik van comedicatie tijdens palliatieve sedatie.

- Palliative sedation is a treatment option for patients in the terminal stage of their disease who have one or more refractory symptoms.- In giving palliative sedation it is important to take into account the pharmacokinetic and pharmacodynamic properties of medications that contribute to good palliation: this covers both medication used in palliative sedation and continued chronic medication.- This article provides tools for clinical practice to deal with the difficulties concerning stopping or continuing chronic medication and on interaction between medications in palliative sedation.

The Distress Thermometer for screening for severe fatigue in newly diagnosed breast and colorectal cancer patients.

OBJECTIVE: Internationally, the Distress Thermometer and associated Problem List are increasingly used in oncology as screening tools for psychological distress. Cancer-related fatigue is common but often overlooked in clinical practice. We examined if severe fatigue in cancer patients can be identified with the fatigue item of the Problem List. METHODS: Newly diagnosed breast (N = 334) and colorectal (N = 179) cancer patients were screened for severe fatigue, which was defined as having a positive score on the fatigue item of the Problem List. The Fatigue Severity subscale of the Checklist Individual Strength was used as gold standard measure for severe fatigue. RESULTS: In total, 78% of breast cancer patients and 81% of colorectal cancer patients were correctly identified with the fatigue item. The sensitivity was 89% in breast cancer patients and 91% in colorectal cancer patients. The specificity was 75% in breast cancer patients and 77% in colorectal cancer patients. The positive predictive value was 53% in breast cancer patients and 64% in colorectal cancer patients, whereas the negative predictive value was 95% in both tumor types. CONCLUSIONS: The fatigue item of the Problem List performs satisfactorily as a quick screening tool for severe fatigue. However, a positive screen should be followed up with a more thorough assessment of fatigue, ie, a questionnaire with a validated cutoff point. Given time pressure of clinicians, this already implemented and brief screening tool may prevent severe fatigue from going undetected in clinical practice.

Severe fatigue after treatment of ductal carcinoma in situ: A comparison with age-matched breast cancer survivors and healthy controls.

PURPOSE: Severe fatigue after treatment of ductal carcinoma in situ (DCIS) has not been studied before. The current study examined (i) the prevalence of severe fatigue in DCIS patients versus breast cancer survivors (BCS) and healthy controls (HC), (ii) quality of life and functioning of severely versus non-severely fatigued DCIS patients and BCS, and (iii) the association of fatigue with psychosocial and behavioral factors in DCIS patients. METHODS: 89 patients treated for DCIS were matched on age and gender to 67 BCS and 178 HC (ratio 1:1:2). Fatigue was measured with the Fatigue Severity subscale of the Checklist Individual Strength. RESULTS: 23% of DCIS patients, 25% of BCS, and 6% of HC were severely fatigued (DCIS versus HC: p < 0.001). Severely fatigued DCIS patients had a lower quality of life and were more impaired in all domains of functioning than non-severely fatigued DCIS patients. Sleep problems, dysfunctional cognitions regarding fatigue, avoidance of activities, all-or-nothing behavior, perceived lack of social support, DCIS-related coping problems, and fear of future cancer occurrence were related to fatigue. CONCLUSIONS: The prevalence of severe fatigue in DCIS patients was similar to BCS, but higher than in HC. Severely fatigued DCIS patients had a lower quality of life and more functional impairments. The psychosocial and behavioral fatigue-related factors in DCIS patients are known to perpetuate fatigue in BCS. These factors can be targeted in interventions for cancer-related fatigue. Our findings suggest that the same treatment elements might be applicable to severely fatigued DCIS patients.

Risk factors, prevalence, and course of severe fatigue after breast cancer treatment: a meta-analysis involving 12 327 breast cancer survivors.

BACKGROUND: This meta-analysis aimed to (i) examine demographic, disease-related, and treatment-related risk factors, (ii) estimate the prevalence, and (iii) describe the course of severe fatigue following breast cancer (BC) treatment. METHODS: PubMed, PsycINFO, Cochrane, CINAHL, and Web of Science were systematically searched from inception up to 23 November 2015. Risk factors and prevalence rates were analyzed with inverse variance random-effects analyses. Heterogeneity was studied with sensitivity analyses. RESULTS: Twenty-seven studies were included (N = 12 327). Breast cancer survivors (BCS) with a partner were at lower risk for severe fatigue than survivors without a partner [risk ratio (RR) 0.96, 95% confidence interval (CI) 0.93-0.98]. Survivors with stage II or III cancer, and survivors treated with chemotherapy were at higher risk for severe fatigue than survivors with stage 0 or I cancer and without chemotherapy (RR respectively 1.18, 95% CI 1.08-1.28; 1.12, 95% CI 1.06-1.19). Survivors treated with surgery, radiotherapy, and chemotherapy, and survivors with this combination plus hormone therapy were at higher risk than survivors with other treatment combinations (RR respectively 1.18, 95% CI 1.05-1.33; 1.38, 95% CI 1.15-1.66). Survivors treated with surgery and surgery plus radiotherapy were at lower risk than survivors with additional treatments (RR respectively 0.83, 95% CI 0.70-0.98; 0.87, 95% CI 0.78-0.96). Hormone and targeted therapy were no significant risk factors. The pooled prevalence of severe fatigue was 26.9% (95% CI 23.2-31.0), but this should be interpreted with caution because of high heterogeneity. A relatively large decrease in the prevalence of severe fatigue seemed to occur in the first half year after treatment completion. CONCLUSIONS: Approximately one in four BCS suffer from severe fatigue. Risk factors of severe fatigue were higher disease stages, chemotherapy and receiving the combination of surgery, radiotherapy, and chemotherapy, both with and without hormone therapy. Having a partner, receiving only surgery, and surgery plus radiotherapy decreased the risk.

A randomized controlled trial of web-based cognitive behavioral therapy for severely fatigued breast cancer survivors (CHANGE-study): study protocol.

BACKGROUND: About one third of breast cancer survivors suffer from persistent severe fatigue after completion of curative cancer treatment. Face-to-face cognitive behavioral therapy (F2F CBT), especially designed for fatigue in cancer survivors, was found effective in reducing fatigue. However, this intervention is intensive and treatment capacity is limited. To extend treatment options, a web-based version of CBT requiring less therapist time was developed. This intervention is aimed at changing fatigue-perpetuating cognitions and behaviors. The efficacy of web-based CBT will be examined in a multicenter randomized controlled trial. METHODS: In total, 132 severely fatigued breast cancer survivors will be recruited and randomized to either an intervention condition or care as usual (ratio 1:1). Participants will be assessed at baseline and 6 months thereafter. The intervention group will receive web-based CBT, consisting of three F2F sessions and maximally eight web-based modules over a period of 6 months. The care as usual group will be on a waiting list for regular F2F CBT. The total duration of the waiting list is 6 months. The primary outcome of the study is fatigue severity. Secondary outcomes are functional impairments, psychological distress and quality of life. DISCUSSION: If web-based CBT is effective, it will provide an additional treatment option for fatigue in breast cancer survivors. Web-based CBT is expected to be less time-consuming for therapists than regular F2F CBT, which would result in an increased treatment capacity. Moreover, the intervention would become more easily accessible for a larger number of patients, and patients can save travel time and costs. TRIAL REGISTRATION: Dutch Trial Registry--NTR4309.

Severe fatigue and related factors in cancer patients before the initiation of treatment.

It is generally known that fatigue is a common symptom during cancer treatment, and in cancer survivors. However, fatigue was never studied after diagnosis, before cancer treatment was initiated. This study investigated the prevalence of severe fatigue, and related factors, in cancer patients before the initiation of treatment. One hundred and seventy-nine patients with various malignancies were assessed before start of treatment with curative intention, including the Checklist Individual Strength, Sickness Impact Profile, Beck Depression Inventory Primary Care, Symptom Checklist-90, and six Numeric Rating Scales to measure fatigue, pain and physical activity. To test which factors contributed to severe fatigue a logistic regression analysis was performed. In total 23.5% patients were severely fatigued, varying between diagnoses; prostate cancer (14.3%), breast cancer (20.3%), and gastrointestinal cancer (28.1%). Currently lower physical activity (P=0.013), more depressive mood (P=0.014), impaired sleep and rest during the day and night (P=0.045), and fatigue 1 year before diagnosis (P=0.005) contributed to severe fatigue. Relatively large numbers of cancer patients already experience severe fatigue before initiation of treatment, varying between 14-28%. The factors that contributed to severe fatigue at this stage were physical activity, depressive mood, impaired sleep and rest, and fatigue 1 year before diagnosis.

Cognitive behaviour therapy for fatigued cancer survivors: long-term follow-up.

An earlier randomised-controlled trial demonstrated the positive effects of cognitive behaviour therapy (CBT), especially designed for fatigued cancer survivors in reducing fatigue, functional impairments and psychological distress. In the current prospective study, we were able to examine the long-term effect of CBT in patients who completed the therapy. Predictors of fatigue severity at follow-up were exploratory investigated. Sixty-eight patients who completed CBT were assessed at pretreatment, post-treatment and at follow-up (mean follow-up 1.9 years (s.d. 1.0), range: 1-4 years). To analyse possible predictors of treatment outcome a linear regression (enter) was carried out. Improvements on fatigue severity, functional impairment and psychological distress after CBT appeared to remain stable during a follow-up period. Patients who were not fatigued anymore at follow-up were not different from a reference group of non-fatigued cancer survivors. The explorative regression analysis showed that fatigue severity, psychological distress and somatic attributions at pretreatment contributed to persistent fatigue severity at follow-up. Cognitive behaviour therapy, especially designed for post-cancer fatigue, is successful in reducing fatigue and functional impairment in cancer survivors. Moreover, these positive effects were maintained at about 2 years after finishing CBT.

Experience of severe fatigue in long-term survivors of stem cell transplantation.

The literature suggests that cancer survivors with more aggressive treatments are more at risk for postcancer fatigue. In this study, we investigated the prevalence of fatigue after completion of stem cell transplantation (SCT). Furthermore, we studied if medical variables are associated with fatigue and if the model of perpetuating factors of postcancer fatigue derived from previous studies in cancer survivors, without SCT, is applicable in SCT survivors. Ninety-eight patients treated with autologous or allogeneic SCT filled out several questionnaires. Medical characteristics were obtained from the medical charts. All patients had to be in persistent complete remission for at least 1 year. Thirty-five per cent of the patients experienced severe fatigue. The percentage of patients with severe fatigue remained stable during the years after transplantation. Several psychosocial factors, but no medical factors, were associated with fatigue. The model of perpetuating factors appeared to be applicable. Contrary to cancer survivors without SCT, we found no decrease in fatigue complaints during the first years after SCT. Cognitive behaviour therapy (CBT) is a general form of psychotherapy directed at changing condition-related cognitions and behaviours. CBT especially designed for postcancer fatigue, aimed at perpetuating factors, can also be used to manage fatigue in cancer survivors treated with SCT.

Cancer cachexia demonstrates the energetic impact of gluconeogenesis in human metabolism.

A review-based hypothesis is presented on the energy flow in cancer patients. This hypothesis centres on the hypoxic condition of tumours, the essential metabolic consequences, especially the gluconeogenesis, the adaptation of the body, and the pathogenesis of cancer cachexia. In growing tumours the O(2) concentration is critically low. Mammalian cells need O(2) for the efficient oxidative dissimilation of sugars and fatty acids, which gives 38 and 128 moles of ATP per mole glucose and palmitic acid, respectively. In the absence of sufficient O(2) they have to switch to anaerobic dissimilation, with only 2 moles of ATP and 2 moles of lactic acid from 1 mole of glucose. Since mammalian cells cannot ferment fatty acids, in vivo tumour cells completely depend on glucose fermentation. Therefore, growth of these tumour cells will require about 40 times more glucose than it should require in the presence of sufficient O(2). Since lactic acid lowers the intracellular pH, it decreases the activity of pyruvate dehydrogenase, stimulates fermentation, and thus amplifies its own fermentative production. Compensatory glucose is provided by hepatic gluconeogenesis from lactic acid. However, the liver must invest 3 times more energy to synthesize glucose than can be extracted by tumour cells in an anaerobic way. The liver extracts the required energy from amino acids and especially from fatty acids in an oxidative way. This may account for weight loss, even when food intake seems adequate. In the liver 6 moles of ATP are invested in the gluconeogenesis of one mole of glucose. The energy content of 4 out of these 6 moles of ATP is dissipated as heat. This may account for the elevated body temperature and sweating experience by cancer patients.

Recombinant human erythropoietin attenuates weight loss in a murine cancer cachexia model.

BACKGROUND: Within hypoxic tumor regions anaerobic dissimilation of glucose is the sole source of energy generation. It yields only 5% of the ATP that is normally gained by means of oxidative glucose catabolism. The increased need for glucose may aggravate cancer cachexia. We investigated the impact of recombinant human erythropoietin (RhEPO) and increased inspiratory oxygen concentrations on weight loss in tumor-bearing mice. METHODS: Fragments of the murine C26-B adenocarcinoma were implanted in 60 BALB/c-mice. The mice were divided into four groups and assigned to: (A) no treatment; (B) RhEPO- administration (25 IU daily from day 1-11, three times per week from day 12); (C) RhEPO and 25% oxygen; and (D) RhEPO and 35% oxygen. Three control groups of four healthy mice each received the same treatment as groups A, B, and D, respectively. Hematocrit and hemoglobin levels, tumor volume, and body weight were monitored. At day 17 the experiment was terminated and the serum lactate concentration was measured. The tumors were excised and weighed and, for each mouse, the percentage weight loss was calculated. The impact of tumor weight and the treatments on lactate concentration and weight loss was evaluated. RESULTS: Significant positive correlations were found between tumor weight and lactate concentration and between tumor weight and percentage weight loss. In the mice with the largest tumors, RhEPO displayed a significant weight loss-reducing effect, and a significant negative correlation was found between hemoglobin concentration and weight loss. An oxygen-rich environment did not appear to influence weight loss. CONCLUSION: Anaerobic glycolysis in a growing C26-B tumor is related to weight loss. RhEPO administration results in a reduction of the percentage weight loss; this effect is probably mediated by an increased hemoglobin concentration.

Chondrosarcoma of bone: functional outcome and quality of life.

BACKGROUND AND OBJECTIVES: Outcome studies of chondrosarcoma have so far only reported oncological and functional results. Quality-of-life assessment becomes more important because more long-term survival after treatment of malignant diseases occur. The objective of this study is to analyze functional outcome and quality of life. METHODS: Functional evaluation of the patients was carried out according to the MSTS functional scoring system. For assessment of quality of life, questionnaires were used. RESULTS: Response of the questionnaires sent to 45 disease-free patients was 84%. The mean functional score of these 38 patients was 74% (20-100%). Best functional results were seen after bone graft reconstruction and curettage and cryosurgery with reconstruction. Quality-of-life analysis revealed a mean global health status of 75 (66-84). Furthermore, 24% of the patients experienced severe fatigue. Patients reported more problems with regard to physical functioning and sleep in comparison with healthy controls. No correlation was found between global health status scores and functional scores. CONCLUSIONS: Functional scores depend on the type of treatment with best results after curettage and cryosurgery. Quality-of-life analysis reveals problems on several domains, including fatigue, physical functioning and sleep.

Organisational design for an integrated oncological department.

OBJECTIVE: The outcomes of a Strength, Weakness, Opportunities and Threat (SWOT) analysis of three Integrated Oncological Departments were compared with their present situation three years later to define factors that can influence a successful implementation and development of an Integrated Oncological Department in- and outside (i.e. home care) the hospital. RESEARCH DESIGN: Comparative Qualitative Case Study. METHODS: Auditing based on care-as-usual norms by an external, experienced auditing committee. RESEARCH SETTING: Integrated Oncological Departments of three hospitals. RESULTS: Successful multidisciplinary care in an integrated, oncological department needs broad support inside the hospital and a well-defined organisational plan.

Quality of adjuvant chemotherapy in primary breast cancer in a non-trial setting. A comprehensive cancer centre study. The Breast Cancer Group of the Dutch Comprehensive Cancer Centre East (IKO).

The quality of adjuvant chemotherapy with cyclophosphamide, methotrexate and 5-fluorouracil (CMF) and the compliance with guidelines for this treatment were studied in 323 premenopausal patients with node positive breast cancer, who were treated in the Comprehensive Cancer Centre East of The Netherlands (IKO) from 1988 to 1992, outside the setting of a clinical trial. The interval surgery-chemotherapy, the duration of chemotherapy, dose intensity (DI) and relative dose intensity (RDI) of CMF chemotherapy and validations of dose modifications were evaluated. 295 of 323 patients (91%) received adjuvant chemotherapy. CMF chemotherapy was used in 230 patients (78% of the chemotherapy receiving patients). The median time to the start of chemotherapy was 62 (range-35-139) days after surgery. Forty-two per cent of the patients finished their CMF chemotherapy within 168 days. Two per cent of the patients did not finish the six courses of CMF chemotherapy. The mean DI and RDI of the eligible patients in all CMF using hospitals were 80.4 +/- 28.8% and 78.2 +/- 28.4%, respectively. Aberrations of recommended guideline procedures resulted more often in suboptimal treatment than haematological toxicity. Adherence to the guidelines was variable and resulted in suboptimal adjuvant chemotherapy. The median follow-up of the patients treated in hospitals that agreed to the use of CMF was 5 years. The mean RDI of CMF in the eligible patients who relapsed was 72.2 +/- 32.7%, compared with 81.4 +/- 25.2% for the patients who did not relapse (P 0.01), suggesting a possible influence of the RDI on disease free survival. However, when the patients who did not receive chemotherapy were excluded, the mean RDI of the patients who relapsed was 85.0 +/- 12.6% and of the patients who did not relapse 87.4 +/- 12.6%, which was not significantly different (P = 0.20).

Pancreatic islet cell tumor producing vasoactive intestinal polypeptide and calcitonin.

A patient with a pancreatic islet cell tumor concurrently producing vasoactive intestinal polypeptide (VIP) and calcitonin with related symptoms is presented. The patient was given palliative treatment consisting of octreotide, streptozotocin and 5-fluorouracil, and survival now exceeds 72 months. The concurrent production of VIP and calcitonin by a pancreatic islet cell tumor has not been described before.
