Exploration of the Accuracy of CT-enhanced Scanning in Evaluating the Pathological Staging of Renal Clear Cell Carcinoma and the Value of Surgical Guidance
Objective:To investigate the accuracy and surgical guidance value of CT-enhanced scanning in assessing the pathologic staging of renal clear cell carcinoma,to provide clinical reference.Methods:126 cases of renal clear cell carcinoma patients admitted to the hospital from March 2021 to March 2022 were selected as the study subjects,and were divided into Group A(30 cases with pathological diagnosis of Stage Ⅰ),Group B(35 cases with pathological diagnosis of Stage Ⅱ),Group C(31 cases with pathological diagnosis of Stage Ⅲ),and Group D(30 cases with pathological diagnosis of Stage Ⅳ)according to the results of the surgical pathology and histologic biopsy.All patients underwent CT plain scanning and enhancement scanning.The detection of different pathological stages under different scanning modalities was compared,and the imaging characteristics and CT values of the four groups of patients under different scanning modalities were compared.Results:The detection rates of patients with different pathologic stages under CT enhanced scanning were higher than those of CT plain scanning,and the differences were statistically significant(x2=14.398,13.226,9.517,22.222,P＜0.05).Under enhanced scanning,the difference in CT values among the 4 groups of patients was statistically significant(F=14.900,P＜0.05).Under enhanced scanning,the rate of vascular tissue invasion and metastasis of the lesion was higher in patients with stage IV than in other patients.Conclusion:CT-enhanced scanning can accurately evaluate the pathological stage of patients with renal clear cell carcinoma by observing the CT value,vascular invasion of surrounding tissues and distant metastasis,and the combination of CT-enhanced scanning results can effectively guide the surgical treatment of the patients,which is of great significance in improving the prognosis of the patients.
