Evaluation and Management of Fatigue in Oncology: A Multidimensional Approach
Department of Medical Oncology, National Institute of Oncology, Rabat, Morocco.Indian Journal of Palliative Care 05/2011; 17(2):92-7. DOI: 10.4103/0973-1075.84528
Fatigue, one of the most common symptoms experienced by cancer patients, is multidimensional and is associated with significant impairment in functioning and overall quality of life. Although the precise pathophysiology of cancer-related fatigue (CRF) is not well understood, a number of metabolic, cytokine, neurophysiologic, and endocrine changes have been described in these patients. A better understanding of these abnormalities is likely to lead to novel therapeutic interventions. Clinically, all patients presenting with significant fatigue should be evaluated for treatable conditions that might contribute to this symptom. Exercise and treatment of anemia are the two most established interventions for CRF. Psychostimulants seem promising based on early studies. Several complementary medicine treatments that showed efficacy in preliminary studies merit further testing.

ABSTRACT: Indian Journal of Palliative Care (IJPC) provides a comprehensive multidisciplinary evidence base for an evidence-informed clinical decision making. To analyze the levels of evidence of articles published in IJPC in the years 2010-2011. Systematic review of palliative care journals. Systematic review of articles was done and was scored according to Center for Evidence-Based Medicine levels of evidence into any of the five grades. The articles were categorized based upon article type, number of authors, study approach, age focus, population focus, disease focus, goals of care, domains of care, models of care, and year of publication. All descriptive analysis was done using frequencies and percentiles, and association between all categorical variables was done using Chi-square test at 95% confidence interval (CI) using Statistical Package for Social Sciences (SPSS) version 16 for Windows (SPSS Inc, Chicago, IL). There was a greater prevalence of low level evidence (level 4: n = 46, 51%; level 5: n = 35, 39%) among the 90 selected articles, and article type (original articles with higher level of evidence, P = 0.000), article approach (analytical studies with higher level of evidence, P = 0.000), domains of palliative care (practice-related studies with higher level of evidence, P = 0.000) and models of care (biological or psychosocial model with higher level of evidence, P = 0.044) had a significant association with the grade of levels of evidence. Association with other factors was not statistically significant (P < 0.05). The levels of research evidence for palliative care provided by articles published in IJPC were predominantly level 4 and level 5, and there is scope for more high quality evidence to inform palliative care decisions in the developing countries.Indian Journal of Palliative Care 02/2013; 19(3):170-179.

ABSTRACT: Purpose: Mitochondrial dysfunction is a plausible biological mechanism for cancer-related fatigue. Specific aims of this study were to (1) describe the levels of mitochondrial oxidative phosphorylation complex (MOPC) enzymes, fatigue, and health-related quality of life (HRQOL) before and at completion of external beam radiation therapy (EBRT) in men with nonmetastatic prostate cancer (PC); (2) examine relationships over time among levels of MOPC enzymes, fatigue, and HRQOL; and (3) compare levels of MOPC enzymes in men with clinically significant and nonsignificant fatigue intensification during EBRT. Methods: Fatigue was measured by the revised Piper Fatigue Scale and the Functional Assessment of Cancer Therapy-Fatigue subscale (FACT-F). MOPC enzymes (Complexes I-V) and mitochondrial antioxidant superoxide dismutase 2 were measured in peripheral blood using enzyme-linked immunosorbent assay at baseline and completion of EBRT. Participants were categorized into high or low fatigue (HF vs. LF) intensification groups based on amount of change in FACT-F scores during EBRT. Results: Fatigue reported by the 22 participants with PC significantly worsened and HRQOL significantly declined from baseline to EBRT completion. The HF group comprised 12 men with clinically significant change in fatigue (HF) during EBRT. Although no significant changes were observed in MOPC enzymes from baseline to EBRT completion, there were important differences in the patterns in the levels of MOPC enzymes between HF and LF groups. Conclusion: Distinct patterns of changes in the absorbance of MOPC enzymes delineated fatigue intensification among participants. Further investigation using a larger sample is warranted.Biological Research for Nursing 11/2015; DOI:10.1177/1099800415617848 · 1.43 Impact Factor
