Abstract
Background Traditional Chinese Medicine Astragalus was commonly used to assist chemo-drug treatment in clinical cancer patients. However, whether Astragalus injection (AGI) reverses drug resistance remains unclear. Therefore, a meta-analysis is necessary to assess the effect of AGI on resistance reversement in cancer patients. Method The studies presenting tumor response rates in cancer patients receiving chemo-drugs treatment in combination with AGI were systematically searched from six common scientific databases until February 2024. The relative risks (RRs) indicating the tumor response rate, 1-year survival rate, and quality of life improvement in clinical patients among two groups were calculated in metan package. The pooled RRs with 95% confidence intervals (CIs) were used to explore the effect of AGI on enhancing drug sensitivity in terms of tumor response, 1-year survival rate and quality of life improvement in cancer patients. Result Fifty-one studies were included for meta-analysis following a thorough screening process that adhered to the inclusion and exclusion criteria. A total of 4613 patients were enrolled in all included trials. Results obtained indicated that AGI significantly enhanced the sensitivity of cancers to chemo-drugs with pooled RRs (95% CI) of 1.25 (1.18, 1.32), prolonged the 1-year survival rate of patients with pooled RRs (95% CI) of 1.34 (1.14, 1.57), improved the quality of life with pooled RRs (95% CI) of 1.61 (1.34, 1.93). Similarly, Astragalus's main component, astragaloside polysaccharides (APS), also enhances drug sensitivity in clinical cancer patients. Conclusion Our findings demonstrated that AGI had the ability to resensitize cancers to chemo-drugs and improve the quality of life of cancer patients. Therefore, AGI could potentially be used as a drug resistance reversal for resistant cancer treatment.
