Abstract
We performed a meta-analysis to evaluate the influence of Chinese herbal medicines on cancer-related pressure ulcer wounds, fatigue, constipation, and anorexia. A systematic literature search up to March 2022 was done and 25 studies included 1777 subjects with cancer-related symptoms at the start of the study; 953 of them were provided with Chinese herbal medicines and 824 were control. They were reporting relationships about the influence of Chinese herbal medicines on cancer-related pressure ulcer wounds, fatigue, constipation, and anorexia. We calculated the odds ratio (OR) with 95% confidence intervals (CIs) to assess the influence of Chinese herbal medicines on cancer-related pressure ulcer wounds, fatigue, constipation, and anorexia using the dichotomous method with a random or fixed-effect model. Chinese herbal medicines had significantly higher effectiveness in treating pressure ulcer wound (OR, 5.94; 95% CI, 3.94-8.95, P < .001), fatigue (OR, 2.81; 95% CI, 1.78-4.41, P < .001), and effectiveness on treating constipation (OR, 2.59; 95% CI, 1.57-4.25, P < .001) compared to control in subjects with cancer-related symptoms. However, Chinese herbal medicines had no significant effect on treating anorexia (OR, 1.69; 95% CI, 0.61-4.66, P = .31) compared to control in subjects with cancer-related symptoms. Chinese herbal medicines had significantly higher effectiveness in treating pressure ulcer wound, treating pressure ulcer wound, fatigue, and constipation compared to control in subjects with cancer-related symptoms. However, Chinese herbal medicines had no significant effect on the effectiveness of treating anorexia compared to control in subjects with cancer-related symptoms. Further studies are required to validate these findings.
