Study on Variation Trend of Pre-treatment Blood Human Chorionic Gonadotropin in Predicting Efficacy of Tubal Pregnancy Treated by Drug Therapy
Objective To investigate the role of variation trend of pre-treatment blood beta human chorionic gonadotropin(β-HCG)in predicting the efficacy of tubal pregnancy(TP)treated by drug therapy.Methods Clinical data of 380 TP patients treated by drug therapy at the First Affiliated Hospital of Guangzhou University of Chinese Medicine from January 2017 to June 2022 were collected.The patients were divided into 271 cases in the pure Chinese medicine(CM)treatment group(shortened as pure CM group)and 109 cases in the combination of Chinese medicine and western medicine group(shortened as combination group)according to the therapy.The relevant factors that may affect the outcomes of the therapy were analyzed,and logistic regression analysis was used for the control of confounding factors.The influences of pre-treatment β-HCG on the outcomes of TP treated by various therapies were investigated,and the value of variation trend of pre-treatment β-HCG in predicting the efficacy of TP treated by drug therapy was assessed using the receiver operating characteristic curve(ROC curve).Results(1)The results of univariate analysis showed that the initial value of blood β-HCG,the variation trend of β-HCG and the difference value of β-HCG detected for 2 times before treatment were correlated with the treatment outcomes in the pure CM group and the combination group,and the differences were all statistically significant(P＜0.05 or P＜0.01).(2)The results of multivariate regression analysis showed that in the pure CM group,the blood β-HCG values and the variation trend of β-HCG detected for 2 times before treatment were correlated with the treatment outcomes,and the differences were all statistically significant(P＜0.05 or P＜0.01);in the combination group,the menopausal time and blood β-HCG value detected at the second time before treatment were correlated with the treatment outcomes,and the differences were all statistically significant(P＜0.05).(3)After controlling for the confounding factors,the variation trend of pre-treatment β-HCG in the pure CM group was correlated with the treatment outcomes,and the difference was statistically significant(OR=3.35,95%CI being 1.69-6.65,P = 0.001).However,the variation trend of pre-treatment β-HCG in the combination group did not affect the treatment outcomes,and the difference was not statistically significant(P＞0.05).(4)The ROC curve analysis showed that the area under the curve(AUC)in the pure CM group was 0.74,the cutoff value was-0.14,the sensitivity was 71.3%and the specificity was 67.8%.The AUC in the combination group was 0.67,the cutoff value was 0.10,the sensitivity was 73.6%and the specificity was 60.7%.Conclusion The variation trend of pre-treatment blood β-HCG can effectively predict the efficacy of Chinese medicine for the treatment of TP,but has no value for predicting the efficacy of the combination of Chinese medicine and western medicine in treating TP.The variation value of pre-treatment blood β-HCG can be used as a valuable reference indicator for the early prediction of the outcomes of TP treated by drug therapy.
