Comparison of preoperative CT scan results with histopathological findings after renal cell carcinoma in terms of staging and invasion of surrounding adipose tissue by Sahar Zomorodi

Abstract

Renal cell carcinoma is the eighth cancer in humans and one third of patients have metastases at the time of diagnosis, definitive diagnosis and staging before surgery, and after surgery it is important to compare the findings with imaging and pathological findings after surgery. The purpose of this study is to compare the preoperative CT scan results with the postoperative histopathology findings of renal cell carcinoma in terms of staging and invasion of the surrounding fat tissue. Materials and methods In this study, a cross-sectional survey of all patients who from 1389 to the end of 1399 referred to the urology department of Imam Reza Medical Education Center in Tabriz and underwent CT-Scan and then surgery due to suspicion of kidney tumor and met the inclusion criteria It was investigated to study whether they were. CT-Scan report information of patients was extracted from the hospital's PEX system and pathology information of the patients was extracted from the hospital's HIS system. The CT-Scan report included tumor location, tumor size, local invasion, vascular invasion, lymphatic invasion, tumor characteristics (Solid mass, Bosniak lesion type) and pathology information including tumor type, tumor size, local invasion, vascular invasion, lymphatic invasion. and the classification was TNM. Then the histological and CT scan findings of the patients were compared. Results According to the obtained results, the highest number of kidney tumor sufferers are men with a higher frequency percentage, and also the highest incidence of kidney tumor was observed in the right kidney. Examination of the type of tumor showed that the most type of tumor is related to renal cell. It was carcinoma. The examination and comparison between the results of pathology and CT scan showed that the CT scan method significantly showed less invasion of fat tissue than the pathology method, also the tumor invasion rate of vascular and ureteral tissues was significantly lower than the CT scan method. You had less. Also, the size of the tumor was significantly smaller in the CT scan method.
