Comparative Study on Diagnosis Value of Contrast-Enhanced Ultrasound and Contrast-Enhanced Computed Tomography after Treating Advanced Renal Cancer Patients with Yiqi Jiedu Decoction

Abstract

Objective. To compare and analyze the diagnosis value of contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CECT) after treating advanced renal cancer patients with Yiqi Jiedu decoction. Methods. The case data of 60 patients diagnosed with advanced renal cancer from January 2013 to January 2021 at the Affiliated People’s Hospital of Ningbo University were retrospectively analyzed, 30 patients who accepted the conventional treatment were included in the control group, and the rest treated with Yiqi Jiedu decoction on the basis of conventional treatment were included in the study group. After treatment, patients in both groups received the CEUS and CECT examinations, the diagnosis efficacy of both examinations was evaluated with the ROC curve, and the overall survival (OS) of patients was analyzed. Results. No significant between-group differences in the general information were observed ( $P>0.05$ ); the clinical remission rate and disease control rate were not significantly different between the two groups ( $P>0.05$ ); the enhancement and attenuation, degree of enhancement, uniformity of enhancement, and pseudocapsule sign of the CEUS and CECT examinations were not remarkably different ( $P>0.05$ ); according to the results of CEUS and CECT examinations, the maximum diameters of tumor after treatment were smaller in the study group than in the control group, but with no significant between-group difference ( $P>0.05$ ); in addition, there were no obvious differences in determining the maximum diameter of tumor by CEUS and CECT ( $P>0.05$ ), and the results of the maximum diameter of tumor determined by CEUS, CECT, and pathological specimen were not statistically different ( $P>0.05$ ); as for the diagnosis efficacy, the result was CEUS + CECT > CEUS > CECT; and the OS of patients in the study group was longer than those in the control group. Conclusion. The patients treated with Yiqi Jiedu decoction obtain longer OS, and the application value of CEUS combined with CECT in the treatment effect and prognosis of patients with advanced renal cancer is higher.
