Clinical factors associated with cancer-related fatigue in patients being treated for leukemia and non-Hodgkin's lymphoma

Sleep disruption and its contributing factors in Chinese survivors of childhood cancer: A cross-sectional study

OBJECTIVES

This study provided information about sleep disruption, particularly its prevalence and severity among Hong Kong Chinese childhood cancer survivors. Additionally, we identified the factors influencing sleep disruption and explored how fatigue, depressive symptoms and physical activity (PA) affect sleep disruption.

METHODS

402 survivors 6-18 years old and 50 age- and gender-matched healthy counterparts were assessed for depressive symptoms, fatigue, PA and subjective sleep quality. Demographic and clinical information were collected. Multiple logistic regression analyses were conducted to identify any factors contributing to poor sleep.

RESULTS

Mean scores of depressive symptoms, fatigue for children and that for adolescents, and PA in survivors were 16.1 (SD=11.1), 24.6 (SD=10.3), 27.7 (SD=7.8) and 3.08 (SD=2.9), respectively. 44.8% of the survivors were poor sleepers, which was more that in healthy counterparts. The three most common sleep problem were prolonged sleep latency (31.9%), daytime dysfunction (23.4%) and sleep disturbance (22.9%). The time since last treatment (children: AOR=0.54, 95%CI=0.30-0.96, p=.04; adolescents: AOR=0.80, 95%CI=0.70-0.92, p<.01) and PA levels (children: AOR=0.46, 95%CI=0.260-0.82, p=.01; adolescents: AOR=0.70, 95%CI=0.49-0.98, p=.04) were negatively associated with sleep disruption, while depressive symptoms (children: AOR=1.31, 95%CI=1.04-1.64, p=.02; adolescents: AOR=1.07, 95%CI=1.01-1.13, p=.03), fatigue (children: AOR=1.15, 95% CI=1.00-1.31, p=.04; adolescents: AOR=1.08, 95%CI=1.02-1.15, p=.01), number of treatment received (children:AOR=16.56, 95% CI=1.27-216.82, p=.03; adolescents: AOR=7.30, 95%CI=2.36-22.56, p<.01) and co-sleeping (children: AOR=29.19, 95%CI=1.65-511.57, p=.02; adolescents: AOR=4.63, 95%CI=1.22-17.61, p=.02) were positively associated with sleep disruption.

CONCLUSION

PA made the largest contribution to reduce sleep disruption. It is crucial to advocate for the adoption and maintenance of PA in survivorship. This article is protected by copyright. All rights reserved.

Clinically significant symptoms prevalence in breast and colon cancers and leukemia patients: a comparison analysis of patient-reported outcomes

PURPOSE

To assess the prevalence and severity of clinically significant symptoms (CSSs) for breast cancer, colon cancer, and leukemia patients undergoing chemotherapy.

METHODS

A retrospective review of the Edmonton Symptom Assessment System scores reported by patients from the database of our previous large-scale study, which was collected between May 2018 and January 2019. We described the prevalence of CSSs in proportion and severity in mean ± SD.

RESULTS

Of 546 cancer patients, 209 were breast cancer, 159 were colon cancer, and 178 were leukemia. The majority of participants were females 345 (63.2%), and the mean age of the entire study sample was 49.4 ± 13.93. Diminished feeling of well-being was the most prevalent CSS across the three cancers, with a statistically significant difference (p < 0.001). Fatigue (6.59 ± 2.07), pain (6.55 ± 2.01), and loss of appetite were the most distressing CSSs (6.49 ± 1.99) across the whole sample. Loss of appetite (6.34 ± 2.05) was the most distressing CSS in breast cancer, fatigue (6.97 ± 2.07) in leukemia, and pain (7.00 ± 2.11) in colon cancer. Statistically significant differences were found in the severity between the three cancer in pain (p < 0.001), fatigue (p = 0.010), nausea (p = 0.001), and diminished feeling of well-being (p = 0.033). Cancer type, sleeping hours, dependence on caregiver, female gender, level of education, and employment were significantly associated with higher odds of CSS severity.

CONCLUSION

Breast and colon cancer and leukemia patients undergoing chemotherapy experience multiple distressing CSSs. Our study validates CSSs as a discrete set of distressing symptoms that may serve and guide quality of care assessment and cancer clinical research, particularly among patients undergoing chemotherapy.

Effect of Traditional Chinese Medicine Injection on Cancer-Related Fatigue: A Meta-Analysis Based on Existing Evidence

Methods

We systematically searched randomized controlled studies reported through March 2020 in PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, Web of Science, China Biomedical Literature Database (CBM), the China National Knowledge Infrastructure (CNKI), Wanfang, and VIP databases. Two investigators independently screened the studies according to the predetermined criteria, extracted data, and evaluated the bias risk of the included studies, using RevMan5.3 software.

Results

Twelve studies enrolling 1005 participants were included in this systematic review. We found that TCMJ could improve the clinical efficacy of CRF patients (RR = 1.24, 95% CI: 1.05–1.46, P=0.01), ameliorate fatigue status (RR = 1.44, 95% CI: 1.27–1.65, P < 0.00001), and improve quality of life (MD = 8.34, 95% CI: 3.31–13.37, P=0.001), but there was no statistical significance in the fatigue score (MD = −1.10, 95% CI: −2.23–0.04, P=0.06). Referring to the number of adverse events, the safety of TCMJ was good. Subgroup analysis showed that TCMJ could improve clinical efficacy, fatigue, and quality of life in a short time (≤4 weeks). Among them, tonic TCMJ could improve the clinical efficacy. TCMJ had advantages in improving fatigue of lung cancer and gastric cancer. In addition, life quality of lung cancer patients improved significantly.

Conclusion

Current research evidence showed that TCMJ could improve the clinical efficacy, fatigue status, and life quality of patients with CRF. In addition, we found that TCMJ could improve the clinical efficacy of CRF patients in a short period of time. Tonic TCMJ could improve the clinical efficacy, but heat-clearing TCMJ could not. Life quality and fatigue status of lung cancer patients improved significantly. However, due to the sample size and quality of the included studies, the results of this analysis should be treated with caution. The above conclusions still need to be verified by more large-sample and high-quality randomized controlled trials.

Clinically Significant Fatigue in Adult Leukemia Patients: Prevalence, Predictors, and Impact on Quality of Life

Background

Cancer-related fatigue (CRF) is a common distressing symptom in leukemia patients. CRF becomes clinically significant fatigue (CSF) when adversely affects health-related quality of life (HRQoL) and warrants further workup, referrals, and treatment. Objective: To assess the prevalence and predictors of CSF and assesses its impact on HRQoL in adult leukemia patients.

Method

Analysis was performed on 168 leukemia patients. The primary study outcomes were CSF (score ≥4) as measured by the fatigue numerical rating scale and HRQoL using a validated Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu) scale.

Result

The prevalence of CSF was 89 (53%), with a mean score of 6.66±2.02. About 106 (63.1%) of leukemia patients had poor Health-related quality of life (HRQoL) (102.61±23.50). Overall, FACT-Leu mean score indicated that study participants had poor HRQoL (114.70±29.67). There was a statistically significant difference in HRQoL between the patients with CSF 104.89±28.82 and Non-CSF 125.76±26.71, p<0.001. Poor appetite (odd ratio: 3.02 [95% CI: 1.33-6.85]) was statistically significant predictors (p<0.010) of CSF. Dependence on caregiver (odd ratio: 3.31 [95% CI: 0.41-0.75]) and having non-CSF (odd ratio: 5.22 [95% CI: 2.44-11.19]) were found statistically significant predictors of good HRQoL.

Conclusion

CSF is prevalent among leukemia patients, and adversely affects their HRQoL. Holistic assessment and supportive care are needed to reduce the burden of CSF and improve leukemia patients HRQoL.

To assess the Prevalence and Predictors of Cancer-related Fatigue and its Impact on Quality of Life in Advanced Cancer Patients Receiving Palliative Care in a Tertiary Care Hospital: A Cross-sectional Descriptive Study

INTRODUCTION

Cancer-related fatigue (CRF) is one of the adverse outcomes of cancer and its treatment. Despite its high prevalence; the data are scarce from the Indian population on the prevalence of CRF and its predictors in advanced cancer patients. Hence, we aim to find the prevalence of the fatigue, its impact of fatigue on quality of life (QOL), and possible predictors.

METHODS

This study was conducted after approval of the ethical committee in adult patients of advanced cancer receiving palliative care. The data collected included demographic details, nutritional status, any comorbidities involving cardiorespiratory, renal, pulmonary, and neurological system, type and stage of cancer, site of metastasis, any previous or ongoing chemotherapy or radiotherapy, history of drug intake, hemoglobin, and albumin. The study parameters included assessment of fatigue, QOL, and symptom assessment as per the validated tools. The primary objective of the study was to find the prevalence of fatigue in advanced cancer patients receiving palliative care. The secondary objectives were to find predictive factors of fatigue, its impact on QOL of patients, and the relation between the fatigue and QOL receiving palliative care. The correlation between fatigue score and QOL was analyzed using Pearson's correlation coefficient. Multiple linear regression analysis was performed for identifying the predictors of CRF.

RESULTS

The fatigue was observed in all 110 patients in this study. Of these, severe fatigue was seen in 97 patients (Functional Assessment of Chronic Illness Therapy [FACIT]-F < 30). The median (interquartile range [IQR]) FACIT-F score was 14 (8-23). The median (IQR) of the overall QOL was 16.66 (16.6-50). The correlation between the fatigue (FACIT-F) and QOL was + 0.64 (P < 0.001). The predictors of fatigue included pain, physical functioning, Eastern Cooperative Oncology Group, tiredness, and the level of albumin.

CONCLUSION

We conclude that the prevalence of fatigue in Indian patients with advanced cancer receiving palliative care was high and it has a negative impact on QOL. Pain, physical functioning, performance status, and albumin were found to be independent predictors of CRF.

Shenmai injection for the treatment of cancer-related fatigue in advanced non-small cell lung cancer patients undergoing chemotherapy: study protocol for a randomized controlled trial

BACKGROUND

Cancer-related fatigue (CRF) is the most common symptom in patients with advanced non-small cell lung cancer (NSCLC) undergoing treatment with chemotherapy. However, evidence upon which to base management strategies is scarce. Traditional Chinese Medicine (TCM) has been shown to be beneficial to patients with CRF. Chinese herbal injections should be administered under an evidence-based approach. This trial aims to assess the efficacy and safety of the addition of the Shenmai injection (SMI) to conventional therapy for CRF in NSCLC patients undergoing chemotherapy.

METHODS/DESIGN

The study is a two-group, prospective, randomized controlled trial (RCT) designed to evaluate the efficacy and safety of SMI for CRF NSCLC patients undergoing chemotherapy. Eligible participants will be randomized to either a treatment group receiving a 5-day Shenmai injection regimen plus conventional therapy or a control group receiving only conventional therapy. The primary outcome is fatigue, assessed using severity scores from the Functional Assessment for Chronic Illness Therapy-Fatigue (FACIT-F) measurement system. Secondary outcomes include symptom distress scores, depression, sleep disorders, quality of life, and levels of immunologic indicators. Assessments will be carried out at baseline and on day 5 (the end of the intervention).

DISCUSSION

This study can provide evidence to support clinical decision-making in the management of CRF in NSCLC patients undergoing chemotherapy in a way that can be scaled up and used throughout China.

Patient-reported fatigue prior to treatment is prognostic of survival in patients with acute myeloid leukemia

Acute myeloid leukemia (AML) is associated with poor survival. While clinical prognostic factors of survival have been identified, the contribution of patient-reported symptoms has only received marginal attention. Fatigue is one of the most commonly reported symptoms of AML. There is some evidence that fatigue is associated with shorter survival in hematological malignancies. However, the prognostic effects of fatigue in a homogenous cohort of patients with untreated AML has not been tested. We here report results of a prospective study on the prognostic value of patient-reported fatigue prior to onset of treatment, for 2-year survival in 94 AML patients. Cox regression models controlling for demographic and clinical factors showed that those with severe fatigue (22%) had decreased survival rates (Hr = 2.255, 95% CI = 1.16-5.60, p = 0.019). Further exploration showed that fatigue was associated with increased plasma concentrations of IL-6 and TNF-α, but not with demographic or disease-related factors. In conclusion, we here show for the first time that the experience of severe fatigue prior to remission induction chemotherapy (IC) is prognostic for shorter survival in patients with AML of all ages. These findings point to the importance of interventions aimed at relieving fatigue especially before or in the early phases of treatment in order to improve survival.

Cancer-Related Fatigue and Muscle Quality in Hodgkin's Lymphoma Survivors

The purpose of this study was to compare fatigue, strength, body composition, muscle thickness, and muscle quality between Hodgkin's lymphoma survivors (HLS) and apparently healthy subjects matched by age, gender, and physical activity levels (CON). Twelve HLS (32.16 ± 8.06) and 36 CON (32.42 ± 7.64) were enrolled in the study. Fatigue was assessed using the 20-item Multidimensional Fatigue Inventory, muscle strength using an isokinetic dynamometer, body composition using dual-energy X-ray absorptiometry, and thickness and muscle quality using B-mode ultrasound. Differences between HLS and CON were analyzed using independent samples t tests. No significant differences were observed between groups for any demographic characteristics: age ( P = .922), weight ( P = .943), height ( P = .511), body mass index ( P = .796), fat mass ( P = .688), fat-free mass ( P = .520), and percent body fat ( P = .446). No significant differences were observed for strength (peak torque; P = .552), relative peak torque ( P = .200), muscle thickness ( P > .05) and muscle quality ( P > .05). However, self-perceived fatigue was significantly higher in HLS than in CON ( P = .009). It appears that when HLS are matched by age and physical activity levels to CON, no significant difference in body composition, muscle thickness, muscle quality, or strength is observed. Self-perceived fatigue, as predicted, is higher in HLS, which may have implications and should be considered when prescribing exercise training to this cancer population.

Ruxolitinib for symptom control in patients with chronic lymphocytic leukaemia: a single-group, phase 2 trial

Background

Disease-related symptoms impair the quality of life of countless patients with chronic lymphocytic leukemia (CLL) who do not require systemic therapy. Currently available therapies are not specifically aimed at symptom control. Because stimulation of the B-cell receptor activates Janus kinase (JAK)-2 in CLL cells and the JAK2 inhibitor ruxolitinib improves symptoms of patients with myelofibrosis, we hypothesized that ruxolitinib would improve disease-related symptoms in CLL patients.

Methods

Ruxolitinib (10 mg twice daily) was administered to symptomatic CLL patients who did not require systemic therapy for CLL. Scores on the brief fatigue inventory (BFI), CLL module of the MD Anderson symptom inventory (MDASI) and symptom-associated interference in daily activities (interference score; IS), were assessed prior to treatment and after 3 months of treatment. Plasma cytokine/chemokine levels were measured at baseline and at 3 months.

Findings

Forty-one CLL patients (25 untreated and 16 previously treated) were enrolled. Thirty-two (78%) of the participants experienced ≥20% reduction in the average BFI score or in the average MDASI score. 59% of the participants had ≥2 units reduction in worst fatigue score in 24 hours as assessed by the BFI. The mean percentage reductions in BFI, MDASI, and IS scores were >42% (p<0.0001). Improvements in the three symptom scores correlated with reductions in levels of IL-6, C-reactive protein, CXCL10, osteopontin, TNF-α, ICAM-1/CD54, VCAM-1/CD106, and beta-2 microglobulin. Furthermore, treatment with ruxolitinib increased and then decreased lymphocyte counts to baseline levels or lower. Grade 3/4 cytopenias were recorded in three patients.

Interpretation

In CLL patients, ruxolitinib significantly improved disease-related symptoms, reduced cytokine and chemokine levels, and increased and then decreased lymphocyte counts, likely through mobilization followed by apoptosis of CLL cells. Further studies aimed at testing the therapeutic efficacy of ruxolitinib in CLL are warranted.

What do haematological cancer survivors want help with? A cross-sectional investigation of unmet supportive care needs

BACKGROUND

This study aimed to identify the most prevalent unmet needs of haematological cancer survivors.

METHODS

Haematological cancer survivors aged 18-80 years at time of recruitment were selected from four Australian state cancer registries. Survivors completed the Survivor Unmet Needs Survey. The most frequently reported "high/very high" unmet needs items were identified, as well as characteristics associated with the three most prevalent "high/very high" unmet needs reported by haematological cancer survivors.

RESULTS

A total of 715 eligible survivors returned a completed survey. "Dealing with feeling tired" (17%), was the most frequently endorsed "high/very high" unmet need. Seven out of the ten most frequently endorsed unmet needs related to emotional health. Higher levels of psychological distress (e.g., anxiety, depression and stress) and indicators of financial burden as a result of cancer (e.g., having used up savings and trouble meeting day-to-day expenses due to cancer) were consistently identified as characteristics associated with the three most prevalent "high/very high" unmet needs.

CONCLUSIONS

A minority of haematological cancer survivors endorsed a "high/very high" unmet need on individual items. Additional emotional support may be needed by a minority of survivors. Survivors reporting high levels of psychological distress or those who experience increased financial burden as a result of their cancer diagnosis may be at risk of experiencing the most prevalent "high/very high" unmet needs identified by this study.

A randomized, double-blind, 2-period, placebo-controlled crossover trial of a sustained-release methylphenidate in the treatment of fatigue in cancer patients

PURPOSE

This study assessed the efficacy of methylphenidate versus placebo for cancer-related fatigue reduction. Other objectives were to analyze cytokine levels and to determine the effects of methylphenidate on other symptoms, cognitive function, work yield, and patients' perceptions and preferences.

METHODS

Patients were randomly assigned (1:1) to receive methylphenidate-placebo or placebo-methylphenidate for 4 weeks. Patients crossed over after 2 weeks. Wilcoxon signed rank tests and McNemar tests were used to assess continuous and categorical variables. The primary efficacy endpoint was change in the level of worst fatigue on the Brief Fatigue Inventory (BFI) at the end of each 2-week period.

RESULTS

The mean baseline BFI score was moderate (5.7). Methylphenidate treatment did not affect patients' worst level of fatigue or other symptoms. Results from the Wechsler Adult Intelligence Scale Digit Symbol Test and the Hopkins Verbal Learning Test with BFI interference questions and BFI activity questions showed significant improvement in the methylphenidate-treated patients' verbal learning, memory, visual perception, analysis, and scanning speed. Patients treated with methylphenidate missed significantly fewer work hours owing to health reasons and worked significantly more hours. After 4 weeks, 64% of patients reported that methylphenidate improved their cancer-related fatigue, and 58% wanted to continue treatment. Significant difference in interleukin 6R (positive), interleukin 10 (negative), and tumor necrosis factor α (positive) was noted between the methylphenidate and the placebo group.

CONCLUSIONS

Low-dose methylphenidate did not improve cancer-related fatigue. Patients taking methylphenidate had better cognition and were able to work more hours. Patients tolerated methylphenidate well, and the majority felt better and wanted to continue treatment.

Effects of acupressure on fatigue and depression in hepatocellular carcinoma patients treated with transcatheter arterial chemoembolization: a quasi-experimental study

This study was to examine the effects of acupressure on fatigue and depression in HCC patients undergoing TACE. A quasiexperimental study design was used. Patients were evaluated at five time points: before treatment (T1) and 2, 3, 4, and 5 days after treating TACE (T2, T3, T4, and T5). Fatigue and depression were assessed by a VAS fatigue scale and a VAS depression scale at each time point. TFRS and BDI were administered at T1 and T5. Patients' fatigue and depression were significantly higher at T5 than at T1 in two groups. Fatigue and depression increased in both the experimental and control groups' patients over the five days of hospitalization during which TACE and chemotherapy were administered. The experimental group had significantly less fatigue than the control group, with lower subscale scores on physical, psychosocial, daily, and overall fatigue. There were no differences between the groups on depression. At posttest, the experimental group experienced lower physical, psychosocial, daily, and overall fatigue than the control group. Acupressure can improve fatigue in HCC patients during treatment with TACE but did not alleviate depression. Discharge planning should include home care for management of fatigue and depression.

Measuring symptoms as a critical component of drug development and evaluation in hematological diseases

With the rapid development of new therapies for patients with hematological malignancies, there is an increasing need for patient report of symptom status during all phases of drug testing. The patient's perspective on new treatments reflects treatment tolerability as well as symptom benefit, and may assist patients and clinicians in choosing treatments. Inclusion of patient-reported outcomes, more common in solid-tumor than hematological trials, provides early information about symptoms to guide decisions about appropriate dosing and supportive care needs. We provide a historical overview of the use of patient-reported outcomes and symptom assessment in solid-tumor and hematological drug development, and offer recommendations about methodological issues in the monitoring of symptoms in the drug development process in hematological clinical trials.

A randomized, double-blind, placebo-controlled study of oral coenzyme Q10 to relieve self-reported treatment-related fatigue in newly diagnosed patients with breast cancer

BACKGROUND

Coenzyme Q10 (CoQ10) is a common antioxidant supplement with known cardioprotective effects and potential anticancer benefits.

OBJECTIVES

We performed a randomized, double-blind, placebo-controlled study of oral CoQ10 in female breast cancer patients with the primary objective of determining CoQ10's effects on self-reported fatigue, depression, and quality of life (QOL). Methods Eligible women with newly diagnosed breast cancer and planned adjuvant chemotherapy were randomized to oral supplements of 300 mg CoQ10 or placebo, each combined with 300 IU vitamin E, divided into 3 daily doses. Treatment was continued for 24 weeks. Blood tests, QOL measures, and levels of plasma CoQ10 and vitamin E were obtained at baseline and at 8, 16, and 24 weeks. Mixed-effects models were used to assess treatment differences in outcomes over time.

RESULTS

Between September 2004 and March 2009, 236 women were enrolled. Treatment arms were well balanced with respect to age (range, 28-85 years), pathologic stage (stage 0, 91%; stage 1, 8%; stage II, 1%), ethnicity (white, 87%; black, 11%; Hispanic, 2%), and planned therapy. Baseline CoQ10 levels in the CoQ10 and placebo arms were 0.70 and 0.73 microg/mL, respectively; the 24-week CoQ10 levels were 1.83 and 0.79 microg/mL, respectively. There were no significant differences between the CoQ10 and placebo arms at 24 weeks for scores on the Profile of Mood States-Fatigue questionnaire (least squares means, 7.08 vs 8.24, P = .257), the Functional Assessment of Chronic Illness Therapy-Fatigue tool (37.6 vs 37.6, P = .965), the Functional Assessment of Cancer Therapy-Breast Cancer instrument (111.9 vs 110.4, P = .577), or the Center for Epidemiologic Studies-Depression scale (11.6 vs 12.3, P = .632).

CONCLUSIONS

Supplementation with conventional doses of CoQ10 led to sustained increases in plasma CoQ10 levels but did not result in improved self-reported fatigue or QOL after 24 weeks of treatment.

Prevalence of fatigue among cancer patients receiving various anticancer therapies and its impact on quality of life: a cross-sectional study

Background:

Fatigue is disabling and continuous phenomenon in cancer patients during and after various anticancer treatments which can continue for many years after treatment and definitely it has profound effect on Quality of Life (QOL). However, determining its severity is still underestimated among the cancer patients and also very few studies in the literature exist reporting on Cancer-Related Fatigue (CRF) among Indian population.

Aims:

To find out the prevalence of rate of fatigue in cancer patient receiving various anti cancer therapies. To find out the relative impact of fatigue on QOL.

Materials and Methods:

This cross-sectional observational study included a total 121 cancer patients receiving radiotherapy, chemotherapy, and concurrent chemo-radiation with the age group of above 15 years who fulfilled the inclusion and exclusion criteria. All the patients were assessed for severity of fatigue using Brief Fatigue Inventory (BFI) and for QOL using FACT-G scale while they were receiving the anticancer therapies as an in-patient in the regional cancer centers in Madhya Pradesh, India.

Results:

The severe fatigue was more prevalent in chemotherapy [58/59 (98.30%)], and concurrent chemo-radiation (33/42 (78.57%)) as compared to radiotherapy (Moderate-9/20 (45%) and Severe-9/20 (45%)). Moderate correlations were exhibited between fatigue due to radiotherapy and QOL (r = -0.71, P < 0.01), whereas weak correlation was found between fatigue due to chemotherapy and concurrent chemo-radiation (r = -0.361, P < 0.01 and r = -0.453, P < 0.01, respectively).

Conclusion:

Severity of fatigue was found more after chemotherapy and concurrent chemo-radiation therapy while impact on QOL was more after the radiotherapy.

A comprehensive review of head and neck cancer rehabilitation: physical therapy perspectives

Rehabilitation in relation to cancer can be preventative, restorative, supportive, and palliative. It is recognized that patients may have rehabilitation needs throughout their care pathway. The role of physiotherapy in the cancer rehabilitation is less understood and particularly in the head and neck cancer (HNC) patients. This results in various residual deformities and dysfunctions for the patients with HNC. The objective of this review is to provide detailed information regarding the problems faced after the cancer treatments and rehabilitation of patients who suffered with HNC. The fact that cancer patients are facing several months of chemotherapy and/or radiotherapy and usually major surgery, as well as the direct effect of immobility due to pain, means that muscle wasting, joint stiffness, as well as de-conditioning and fatigue are inevitable. The absence of physiotherapy intervention would be detrimental to patient care and the ability of the patient/family to cope with the effects of the disease or its treatment on their functional capacity and quality of life. Following any treatment for HNC, physical therapy may play an essential role in preventing various complications and helping patients to mitigate impairments, and restoring function of the shoulder joint, neck, and face.

Mechanisms of dexamethasone-induced disturbed sleep and fatigue in paediatric patients receiving treatment for ALL

BACKGROUND

Dexamethasone contributes to high cure rates in paediatric acute lymphoblastic leukaemia (ALL) but significantly and adversely alters sleep and fatigue. Herein we explored three mechanisms (pharmacokinetics, serum albumin and pharmacogenetics) through which dexamethasone may cause debilitating fatigue and disrupted sleep.

METHODS

We enrolled 100 patients on a 10-d study: 5-d of no dexamethasone (OFF DEX) followed by 5-d of dexamethasone (ON DEX) during continuation chemotherapy. Sleep variables were collected with continuous actigraphy on days 1 through 5, both OFF DEX and ON DEX. On days 2 and 5 of each 5-d period, parents and patients 7 years of age and older completed a sleep diary and Fatigue Scale questionnaire. Blood was collected at 0 (pre-dexamethasone), 1, 2, 4 and 8 h after the first oral dexamethasone dose for pharmacokinetic analysis. Serum albumin concentration was retrospectively analysed in stored samples. Patient DNA was genotyped for 99 polymorphic loci in candidate genes associated with glucocorticoid metabolism.

RESULTS

Dexamethasone clearance was significantly greater in younger patients than in older ones and in lower risk patients. In multiple regression models, risk group was significantly related to pharmacokinetic parameters. We found that polymorphisms in three genes (AHSG, IL6, POLDIP3) were significantly associated with sleep measures but not with fatigue.

CONCLUSION

Risk group had the most significant relationship with disrupted sleep in patients while on dexamethasone. Serum albumin levels had neither a direct relationship with sleep or fatigue variables nor an indirect relationship through systemic exposure to dexamethasone. We identified candidate genes that may help explain the adverse events of disrupted sleep in paediatric patients receiving dexamethasone.

Inflammatory biomarkers and fatigue during radiation therapy for breast and prostate cancer

PURPOSE

Biomarkers of radiation-induced behavioral symptoms, such as fatigue, have not been identified. Studies linking inflammatory processes to fatigue in cancer survivors led us to test the hypothesis that activation of the proinflammatory cytokine network is associated with fatigue symptoms during radiation therapy for breast and prostate cancer.

EXPERIMENTAL DESIGN

Individuals with early-stage breast (n = 28) and prostate cancer (n = 20) completed questionnaires and provided blood samples for determination of serum levels of interleukin 1beta (IL-1beta) and IL-6 at assessments conducted before, during, and after a course of radiation therapy. Serum markers of proinflammatory cytokine activity, including IL-1 receptor antagonist and C-reactive protein, were examined in a subset of participants. Random coefficient models were used to evaluate the association between changes in cytokine levels and fatigue.

RESULTS

As expected, there was a significant increase in fatigue during radiation treatment. Changes in serum levels of inflammatory markers C-reactive protein and IL-1 receptor antagonist were positively associated with increases in fatigue symptoms (Ps < 0.05), although serum levels of IL-1beta and IL-6 were not associated with fatigue. These effects remained significant (Ps < 0.05) in analyses controlling for potential biobehavioral confounding factors, including age, body mass index, hormone therapy, depression, and sleep disturbance.

CONCLUSIONS

Results suggest that activation of the proinflammatory cytokine network and associated increases in downstream biomarkers of proinflammatory cytokine activity are associated with fatigue during radiation therapy for breast and prostate cancer.

A framework for assessment in oncology rehabilitation

Although the incidence of cancer in the United States is high, improvements in early diagnosis and treatment have significantly increased survival rates in recent years. Many survivors of cancer experience lasting, adverse effects caused by either their disease or its treatment. Physical therapy interventions, both established and new, often can reverse or ameliorate the impairments (body function and structure) found in these patients, improving their ability to carry out daily tasks and actions (activity) and to participate in life situations (participation). Measuring the efficacy of physical therapy interventions in each of these dimensions is challenging but essential for developing and delivering optimal care for these patients. This article describes the acute and long-term effects of cancer and its treatment and the use of the World Health Organization's International Classification of Functioning, Disability and Health (ICF) as a basis for selection of assessment or outcome tools and diagnostic or screening tools in this population.

Pathophysiology of cancer-related fatigue

Cancer-related fatigue (CRF) is influenced and modulated by a number of critical factors, and the mechanism that is both necessary and sufficient to induce development of severe fatigue in patients with cancer has not yet been identified. Specific research efforts to understand the factors that may contribute to CRF development have been made, including studies of the direct effects of tumor burden, the effects of cancer treatment, and other pathophysiologic and psychosocial conditions. Compelling new hypotheses regarding CRF pathophysiology have been proposed, such as the pro-inflammatory hypothesis, the serotonin hypothesis, the vagal-afferent-activation hypothesis, the anemia hypothesis, and the adenosine triphosphate hypothesis; some of these have been tested in both animal models and humans and some in animals only. Gaining an understanding of the specific mechanisms related to the development of fatigue in patients with cancer and survivors requires further investigation. Pathophysiologic research in CRF could be applied in the clinic to improve CRF diagnosis and to enable administration of mechanism-driven interventions. A targeted intervention study with CRF as a primary end point also would be useful.

Clinical factors associated with fatigue over time in paediatric oncology patients receiving chemotherapy

The purpose of this study was to investigate the relationships between clinical factors (including haemoglobin value, chemotherapeutic agents, and corticosteroid use) and changing patterns of fatigue before and for the next 10 days following the start of a new round of chemotherapy in children with cancer. A prospective longitudinal design was used to collect data from 48 paediatric oncology patients who were about to begin a new round of chemotherapy and their parents. Fatigue levels were assessed using multidomain questionnaires with three categories of patient self-report (including 'General Fatigue', 'Sleep/Rest Fatigue', and 'Cognitive Fatigue') and four categories of parent proxy-report (including 'Lack of Energy', 'Unable to Function', 'Altered Sleep', and 'Altered Mood'). The findings suggest that fatigue from both patient self-report and parent proxy-report changed significantly over time. The major findings from this study are that patients have more problems with fatigue in the first few days after the start of a cycle of chemotherapy. Corticosteroid use and haemoglobin value were associated with significant increases in fatigue that were sustained for several days and reached the highest level of fatigue at day 5 for those receiving concurrent steroids. The association of chemotherapeutic agents with fatigue varied between patient self-report and parent report, but the type of chemotherapeutic agents used was not associated with most changes in fatigue.
