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.
