Existe-t-il une corrélation entre la taille tumorale au scanner et les caractéristiques anatomopathologiques du cancer du rein?

Conclusion La présente étude réaffirme la précision de la TDM pour prédire la taille des tumeurs rénales mesurée à l’anatomopathologie, d’établir le RENAL score afin de mieux orienter le choix thérapeutique et de prédire les caractéristiques anatomopathologique du carcinome à cellules rénales. Introduction Renal cell carcinoma (RCC) may vary in prognosis according to staging, histological subtype, and Fuhrman grade. Hence, accurate evaluation of the renal masses before surgery is essential to ensure an appropriate case management. Purpose To evaluate the value of CT-scan in providing relatively sufficient information about pathologic characteristics of a renal mass and to determine the degree of correlation between radiographic size and true gross pathologic size. Patients and methods We retrospectively reviewed the records of 35 patients who underwent radical or partial nephrectomy for RCC at the department of urology, University Hospital Hassan II, Fez, between 2012 and 2013. Preoperative imaging was performed using CT-scan. Results The mean patient age was 56 years with a male ascendancy, that is a sex ratio of 1.9: 1. The most common histopathological type was the clear-cell Renal Cell Carcinoma. Our study shows that in most instances, imaging by CT insignificantly underestimates true gross pathologic size of RCC (p=0.368). For tumours less than 4cm, the CT-scan significantly overestimate the tumor size (p=0.012). Furthermore, for tumors greater ...
