Objective: To assess the effect and mechanism of composite Xiansu Capsule (CXSC) combined with chemotherapy in treating gastric carcinoma of mid-late stage.
Methods: The 61 patients of the test group were treated by CXSC combined with chemotherapy and 30 patients of the control group treated with chemotherapy alone. The effect of treatment and cell mediated immunity of patients were observed.
Results: The effective rate of the test group and the control group was 32.8% and 13.3% respectively (P < 0.05), the chemotherapy caused toxic reaction occurrence was less in the former than that in the latter group (P < 0.01). The CD3 level of patients in the test group was decreased, and CD4/CD8 level was raised obviously, which suggested that CXSC had immuno-regulating effect on T-cells.
Conclusion: CXSC could enhance the efficacy and reduce the toxic side-effect of chemotherapy. To regulate the cell mediated immunity of patients is possibly its mechanism.
