RESUMEN
BACKGROUND: Quality of life has multiple aspects, but little is known about the effects of exercise on each domain of it. This systematic review aimed to determine the effects of aerobic, resistance, and mixed exercise on multiple aspects of quality of life in patients with cancer through a meta-analysis. METHODS: Randomized controlled trials with quality of life were collected, and 20 studies were analyzed. Subgroup analyses were performed according to exercise types. RESULTS: Exercise improved global, physical, role, and emotional quality of life, but not cognitive and social quality of life. Aerobic, resistance, and mixed exercises improved global, physical, role, emotional, and social quality of life; global, physical and role quality of life; and only physical quality of life, respectively. CONCLUSION: According to exercise type, aerobic and resistance exercises improved global, physical, and role quality of life, whereas aerobic exercise only improved emotional quality of life.

Transcutaneous electrical nerve stimulation (TENS) is primarily used for pain, but might be useful for various other physical symptoms, including nausea, fatigue, dyspnea, and constipation. However, few studies have used TENS for treating the physical symptoms of patients with advanced cancer. In this crossover trial, we assess the effects of TENS on pain and other physical symptoms in 20 in-patients with advanced cancer receiving palliative care. For 5-day phases between wash out periods of 5 days, patients received TENS or non-TENS. TENS was delivered at four points: the center of the back for mainly nausea and dyspnea, on the back at the same dermatomal level as the origin of the pain (100 Hz), and on both ankle joints for constipation (10 Hz). The intensity of pain and the total opioid dose used during phases were recorded. Physical symptoms were evaluated using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 15 Palliative Care (QLQ-C15-PAL). Hematological and biochemical data were recorded before and after the TENS phase. The average pain and total number of opioid rescue doses were significantly reduced by TENS. TENS tended to improve nausea and appetite loss, but not constipation. There were no effects on hematological and biochemical parameters. Use of TENS could safely improve pain, nausea, and appetite loss in patients with advanced cancer. Although it cannot be used as a substitute for opioids and other pharmaceutical treatment, it may be useful to support palliative care.

PURPOSE: Patients with hematological malignancies often present with reduced muscle and physical functions, which are caused by the disease or related treatment. Moreover, patients with hematological malignancies rapidly develop low hemoglobin levels, and this may affect muscle and physical functions. This study aimed to identify the influence of hemoglobin levels on muscle and physical functions in patients with hematological malignancies. METHODS: Using a cross-sectional study design, this study included 60 patients with hematological malignancies (mean age = 68.0 ± 10.2 years, women 56.7%) who were hospitalized for chemotherapy- and radiotherapy-related side effects and underwent examination for skeletal muscle mass (SMM), muscle strength, physical function, activities of daily living (ADLs), psychological status, and quality-of-life (QOL), including physical symptoms. Participants were divided into 3 groups according to tertiles of hemoglobin levels: low (n = 19), middle (n = 20), and high (n = 21). Evaluation items were compared among the 3 groups. RESULTS: There was no significant difference among the 3 groups in terms of SMM. The low hemoglobin group showed significantly higher values of fatigue and dyspnea and lower values of muscle strength, ADLs, and QOL than the high hemoglobin group. CONCLUSIONS: Hemoglobin levels did not affect SMM; however, muscle weakness, decrease in physical function, physical symptoms such as fatigue and dyspnea, and decline in ADLs and QOL were observed in patients with low hemoglobin levels.

OBJECTIVE: This study aimed to conduct a meta-analysis to establish the effect of exercise interventions on physical symptoms, including fatigue, nausea/vomiting, pain, dyspnea, insomnia, loss of appetite, constipation, and diarrhea in cancer patients and survivors. METHODS: We searched articles published before April 2017 using the following databases: Cochrane Library, PubMed/MEDLINE, CINAHL, Scopus, PEDro, Health & Medical Collection, and Psychology Database. Randomized controlled trials (RCTs) of exercise intervention in cancer patients, which evaluated cancer-related physical symptoms using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30, were included. Symptom scale data were extracted for meta-analysis. Subgroup analyses were performed for exercise types (aerobic, resistance, and mixed exercise programs). RESULTS: Of the 659 articles, 10 RCTs were included in the meta-analysis, of which the mean PEDro score was 5.43 (SD = 1.28). Fatigue, pain, dyspnea, and insomnia were significantly lower in the intervention group than in the control group at postintervention in cancer patients. However, exercise intervention did not promote or suppress nausea/vomiting, loss of appetite, constipation, and diarrhea in cancer patients. The effect of exercise type on each symptom was not different. CONCLUSION: Exercise intervention was confirmed to improve fatigue, pain, and insomnia and might have reduced dyspnea in cancer patients. However, the benefits of exercise on nausea/vomiting, loss of appetite, constipation, and diarrhea were not shown in any exercise type. Further research is warranted to examine the effects of exercise interventions on physical symptoms in cancer patients.
