Abstract:
Objective To discuss the clinical value of tumor components of renal angiomyolipoma(AML)in predicting the efficacy of selective arterial embolization(SAE).Methods The clinical data of 20 patients with AML,who received SAE treatment at the General Hospital of Ningxia Medical University of China between August 2019 and April 2023,were retrospectively analyzed.The pre-SAE and post-SAE total tumor volume,fat volume(FV),non-fat volume(NFV),proportion of FV,proportion of NFV were calculated.Pearson correlation analysis was used to analyze the relationship between the initial volume of each tumor component and the tumor volume reduction rate.Multiple linear regression analysis was used to analyze the factors affecting the tumor volume reduction rate.Results The postoperative tumor volume,FV,and NFV were all significantly reduced when compared with their preoperative values(all P＜0.01).The postoperative proportion of FV was increased,and the postoperative proportion of NFV was decreased(P＜0.05).The postoperative tumor volume reduction value was closely correlated with the volume of tumor components and the presence of rupture(P＜0.05).Multivariate regression analysis revealed that the proportion of NFV was the independent risk factor for reduced tumor size.Conclusion After SAE,the proportion of NFV in AML is decreased.The preoperative measurement of this index can help clinicians to predict the postoperative tumor volume reduction ratio and to evaluate the postoperative efficacy of patients.
