To study the efficacy and side effects of Kang'ai injection combined with TP chemotherapy in the treatment of advanced ovarian cancer.Methods:Patients with advanced ovarian cancer admitted to Hainan Provincial Hospital of Traditional Chinese Medicine from January,2017 to January,2019 were studied.All 166 patients were randomly divided into two groups:a control group(n=83) and an observation group(n=83).The patients in the control group received TP chemotherapy treatment.The patients in the observation group received Kang'ai injection on the basis of TP chemotherapy.The clinical effect and side effects of the two groups were analyzed.Results:Compared with the control group,the total effective rate of tumor control and peritoneal effusion control in the observation group increased significantly after treatment(P<0.05).The improvement rate and stability rate of KPS score in the observation group after treatment were significantly higher than those in the control group(P<0.05).After treatment,CD3+,CD4+ and CD4+/CD8+ in both groups were significantly decreased(P<0.05),while CD8+ was increased with no statistical difference(P>0.05).The absolute value of leukocyte,hemoglobin,neutrophil and lymphocyte in the observation group increased significantly(P<0.05).There was no significant change in the above indexes before and after treatment in the control group(P>0.05).Conclusion:Kang'ai injection combined with TP chemotherapy has obvious clinical effect on patients with advanced ovarian cancer,but it does not cause obvious side effects.
