Is Increasing Physical Activity Necessary to Diminish Fatigue During Cancer Treatment? Comparing Cognitive Behavior Therapy and a Brief Nursing Intervention with Usual Care in a Multicenter Randomized Controlled Trial

BACKGROUND Two interventions for fatigue were given during curative cancer treatment. The aim of this multicenter randomized controlled trial (RCT) with three conditions was to demonstrate the efficacy and to determine the contribution of physical activity. METHODS Recruited from seven hospitals, 220 patients with various malignancies participated in a RCT. The brief nursing intervention (BNI) consisted of two 1-hour sessions, 3 months apart, given by 12 trained nurses, focusing only on physical activity. Cognitive behavior therapy (CBT) consisted of up to ten 1-hour sessions, within 6 months, provided by two therapists, focusing on physical activity and psychosocial elements. The control group received only usual care (UC). Assessments took place before and at least 2 months after cancer treatment, when patients had recovered from acute fatigue. Fatigue was the primary outcome. Efficacy was tested using analyses of covariance. A nonparametric bootstrap approach was used to test whether the effect on fatigue was mediated by physical activity. RESULTS The CBT group was significantly less fatigued than the UC group. Between the BNI and the UC groups, no significant difference was found in fatigue. The mediation hypothesis was rejected. DISCUSSION CBT given during curative cancer treatment proved to be an effective intervention to reduce fatigue at least 2 months after cancer treatment. The BNI was not effective. Contrary to what was expected, physical activity did not mediate the effect of CBT on fatigue. Thus, the reduction in fatigue elicited by CBT was realized without a lasting increase in physical activity.

Management of fatigue in patients with cancer – A practical overview

Cancer-related fatigue (CRF) is a serious clinical problem and is one of the most common symptoms experienced by cancer patients. CRF has deleterious effects on many aspects of patient quality of life including their physical, psychological and social well-being. It can also limit their ability to function, socialise and participate in previously enjoyable activities. The aetiology of CRF is complex and multidimensional, involving many potentially contributing elements. These include tumour-related factors and comorbid medical/psychological conditions and also side effects associated with anti-cancer therapies or other medications. Barriers to the effective management of CRF exist both on the side of physicians and patients, and as a result CRF often remains unrecognised and undiscussed in clinical practice. A change of approach is required, where fatigue is treated as central to patient management during and after systemic anti-cancer treatment. In this review we summarise factors involved in the aetiology of CRF and the barriers to its effective management, as well as factors involved in the screening, diagnosis and treatment of cancer patients experiencing fatigue. Pharmacological and non-pharmacological approaches to its management are also reviewed. We suggest an algorithm for the process of managing CRF, guided by our experiences in The Netherlands, which we hope may provide a useful tool to healthcare professionals dealing with cancer patients in their daily practice. Although CRF is a serious and complex clinical problem, if it is worked through in a structured and comprehensive way, effective management has the potential to much improve patient quality of life.

A new, simple and objective prognostic score for phase I cancer patients

AIM To ensure safety and optimise efficacy, careful patient selection for participation in oncologic phase I trials is warranted. Therefore, we did a validation study on existing phase I prognostic scores, and subsequently aimed to make an even more simple prognostic score. PATIENTS AND METHODS We retrospectively analysed characteristics and clinical outcome of 122 patients who participated in eight different phase I studies in our centre. A literature search was performed for existing prognostic scores which were validated in our dataset. Additionally, a simple prognostic score able to predict overall survival (OS), progression free survival (PFS), 90-d mortality and duration of participation was developed. RESULTS In our population the median OS was 31 (range 4-241) weeks, median PFS was 10 (range 3-119) weeks. Thirteen patients (11%) died within 90-d and median participation duration was 11 (range 1-119) weeks. Two out of five existing prognostic scores could be validated in this dataset for OS. Based on multivariate analyses a new, objective and simple score, consisting of LDH, sodium and haemoglobin, was tested. High score (2-3 points) compared to low score (0-1) significantly predicted OS (HR 1.878, p = 0.003), PFS (HR 1.156, p = 0.038), participation duration (HR 1.858, p = 0.004) and 90-d mortality (OR 4.200, p = 0.022). CONCLUSION We propose a new prognostic model, using LDH, sodium and haemoglobin, helpful to predict OS, PFS, participation duration and 90-d mortality. Larger multicentre studies are needed to validate this score.

Severe fatigue during the palliative treatment phase of cancer: an exploratory study.

Background: Because of a rise in incidence and more effective treatments, the prevalence of patients with metastatic cancer is increasing fast. When palliative treatment is aimed at maintaining or improving patients’ quality of life, knowledge about severe fatigue is clinically relevant because of its debilitating effect, but at present this information is lacking. Objective: This study investigated the prevalence of severe fatigue in patients with various incurable cancers and whether severe fatigue increased with further treatment lines and differed between various cancers and treatment modalities. In addition, a relationship between severe fatigue and other symptoms was examined. Methods: Patients were asked to fill in the Checklist Individual Strength, European Organization of Research and Treatment of Cancer–Quality of Life Questionnaire C30, and the McGill Pain Questionnaire during palliative anticancer treatment, and hemoglobin levels were collected. Results: Of all participating patients (n = 137), 47% were severely fatigued. Patients who received first line of treatment were significantly less often severely fatigued (40%) compared with patients who received further lines (60%). Significantly more severe fatigue was observed when patients had more pain, dyspnea, appetite loss, nausea, vomiting, and constipation. Conclusions: During the phase of palliative anticancer treatment, fatigue was the most common symptom, nearly half of the patients had severe fatigue increasing with further treatment lines. Various treatment-related symptoms were related to more severe fatigue. Implications for Practice: As severe fatigue is significantly related to other symptoms of cancer and its treatment, the screening and treatment of these cancer-related symptoms should be more stringent, as they might negatively influence each other.

Exploring the contribution of psychosocial factors to fatigue in patients with advanced incurable cancer

Fatigue is the most frequently occurring and distressing symptom in patients with advanced cancer, caused by multiple factors. Neither a specific histological diagnosis of malignancy nor the type of anticancer treatment seem to be strongly related to fatigue, which support the idea that other factors may play a role. This study investigated to what extent the model of fatigue‐perpetuating factors that is known for cancer survivors was applicable for patients with advanced cancer.

Moderators and long-term effectiveness of cognitive behaviour therapy for fatigue during cancer treatment

A randomised controlled trial (RCT) demonstrated that cognitive behaviour therapy (CBT) for fatigue during curative cancer treatment was effective shortly after cancer treatment. This study aimed to identify which patient characteristics predict fatigue improvement after CBT. In addition, the long‐term effectiveness was investigated.

A prospective analysis on fatigue and experienced burden in informal caregivers of cancer patients during cancer treatment in the palliative phase

Abstract Background. Although fatigue is the most frequently occurring symptom in patients with cancer, hardly anything is known about fatigue of their informal caregivers and the impact fatigue might have on perceived burden with providing care. We investigated the presence of fatigue in caregivers, its course and the relation of fatigue severity between caregivers and patients. Furthermore, we explored in caregivers whether fatigue severity was correlated to experienced burden. Material and methods. Informal caregivers and patients on cancer treatment in the palliative phase completed questionnaires at baseline and follow-up (6 months later). To measure fatigue severity, both groups completed the Checklist Individual Strength. Additionally, caregivers completed the Caregivers Strain Index to assess experienced burden with providing care. Descriptive analyses, paired t-tests, χ2-tests, Pearsons correlations and regression analysis were performed. Results. At baseline 111 couples (patients and caregivers) participated, at follow-up 75 couples. At both time points 23% of caregivers were severely fatigued. There was no significant correlation between patients and caregivers on fatigue. Higher fatigue in both patients and caregivers was correlated with higher burden in caregivers and over 30% of burden could be explained by fatigue. Conclusion. Almost a quarter of caregivers of patients on active palliative treatment were severely fatigued, which figure remained stable over time. Fatigue in both patients and caregivers was related to caregivers’ burden. This observation should be taken into account with the growing demand on caregivers and the increase in cancer treatment options in the palliative setting.

The effectiveness of a nurse-led intervention with the distress thermometer for patients treated with curative intent for breast cancer: design of a randomized controlled trial

BackgroundDistress in patients with cancer influences their quality of life. Worldwide, screening on distress with the Distress Thermometer (DT) in patients with cancer is recommended. However, the effects of the use of the DT on the psychosocial wellbeing of the patient are unknown. A study to assess the psychosocial consequences of the systematic use of the DT and its discussion by a nurse as compared to the usual care provided to outpatients who are treated for primary breast cancer is needed.Methods/designThe effectiveness of a nurse-led intervention with the DT will be tested in a non-blinded randomized controlled trial. Patients treated with curative intent for breast cancer will be recruited from the Radboud University Medical Center. The intervention consists of the DT together with discussion of the results with the patient by a trained oncology nurse added to the usual care. Patients will be randomly allocated (1:1) to either receive usual care or the usual care plus the intervention. Primary outcome measure is global quality of life measured with the EORTC QLQ-C30. The functional and symptom scales of the EORTC QLQ-C30 and BR23, Hospital Anxiety and Depression Scale, Impact of Event Scale, Illness Cognition Questionnaire and DT (baseline and final measurement only) will be used to measure secondary outcomes. Questionnaires are obtained in both arms at baseline, after completion of each type of cancer treatment modality and during follow up, with a three and six months’ interval during the first and second year respectively.DiscussionThis study will be the first randomized controlled longitudinal study about the effectiveness of the DT as nurse led-intervention. In case of proven effectiveness, future implementation and standardization of use of the DT as part of routine care will be recommended.Trial registrationThis study is registered at clinicaltrial.gov march 17, 2010 (NCT01091584).

Exploring the Routine Administration of Decision Aids for Palliative Chemotherapy to Patients by Nurses: A Qualitative Study Among Nurses and Oncologists

Background: Decision aids (DAs) effectively support patient decision making but are rarely used in daily practice. Objective: To explore nurses’ and oncologists’ views on routinely offering DAs on palliative chemotherapy to patients by nurses. Most interviewees had clinical experience with the DAs, which were booklets administered to patients by nurses. Methods: The study was guided by 3 theoretical implementation models of innovations in clinical practice, including factors related to the innovation, the professionals (nurses and oncologists), the patient, and the organization. Semistructured interviews were conducted among 12 nurses and 14 oncologists. Interviews were audio taped and fully transcribed. Results: The main barriers to routinely offering DAs to patients were found in nurses’ and oncologists’ opinions and attitudes (eg, concerns about the impact in this vulnerable population) and in the logistics of organizations (eg, the decision is already made before the nurse sees the patient). Twenty-two of 26 interviewees were open to the future use of the DAs. Disseminating information to professionals (eg, about positive effects of DAs) and embedding DAs in the existing workflow would facilitate implementation. Conclusions: Most nurses and oncologists were open to the future use of the DAs by nurses, provided that certain barriers, particularly related to professionals’ opinions and attitudes and logistical procedures in the organization, could be overcome. Implications for Practice: These findings can inform a tailored strategy to implement DAs on palliative chemotherapy. Implementation should start with interventions to motivate professionals, for example, educational meetings.
