“…In TNM sub-group analysis of Stage III, we found that the sensitivities of perirenal fat and renal vein invasions were 15.4% and 11.3%, respectively. Although these values are very low compared to values reported in other studies (15), other studies also showed that peri-nephric fat and renal vein invasion in RCC are difficult to evaluate radiologically (5). By using the Surveillance Epidemiology and End Results registries Srivastava et al reported that from the patients undergoing partial nephrectomy, the estimated proportion up-staged to pT3a was 9.5%, and 19.5% for cT1b, and cT2, respectively (5).…”

“…Although the accuracy of CT and MRI in the diagnosis and staging of RCC is generally high, the sensitivity and specificity values are found to be lower in T3 cases compared to other stages (15). Renard et al, retrospectively, investigated the diagnostic accuracy of CT in predicting pT3a RCC in 96 cases (15). Renal sinus fat infiltration, peri-nephric fat infiltration and renal venous wall involvement were assessed by two radiologists specialized in urological imaging and compared with the histopathologic staging.…”

Objective: To evaluate the accuracy of radiological staging, especially renal venous and perirenal fat invasion, in renal cell carcinoma (RCC). Material & Methods: Data of 4823 renal tumor patients from Renal Tumor Database of Association of Uro-oncology in Turkey were evaluated. Of 4823 patients, 3309 RCC patients had complete radiological and histopathological data were included to this study. The Pearson Chi-squared test (χ2) was used to compare radiological and histopathological stages. Results: The mean (SD) age of 3309 patients was 58 (12.3). Preoperative radiological imaging was performed using computed tomography (CT) (n=2510, 75.8%) or magnetic resonance imaging (MRI) (n=799, 24.2%). There was a substantial concordance between radiological and pathological staging (к=0.52, p<0.001). Sensitivities of radiological staging in stage I, II, III and IV were 90.7%, 67.3%, 27.7% and 64.2%, respectively. The sensitivity in stage III was lower than the other stages. Sub-analysis of stage IIIa cases revealed that, for perirenal fat invasion and renal vein invasion, sensitivity values were 15.4% and 11.3%, respectively. Conclusions: There was a substantial concordance between radiological (CT and/or MRI) and pathological T staging in RCC. However, this is not true for T3 cases. Sensitivity of preoperative radiological imaging in patients with pT3a tumors is insufficient and lower than the other stages. Consequently, preoperative imaging in patients with T3 RCC has to be improved, in order to better inform the patients regarding prognosis of their disease.
