Popis: | OBJECTIVES To evaluate whether the clinical grade predicts the final pathologic stage in upper urinary tract transitional cell carcinoma. METHODS We retrospectively reviewed the records of 184 consecutive patients undergoing nephroureterectomy for upper urinary tract transitional cell carcinoma at our institution from 1986 to 2004. Their clinical, surgical, and pathologic data were reviewed to determine the positive and negative predictive values of the clinical biopsy grade with respect to the final pathologic disease stage. RESULTS Of the 184 patients, 119 (64.7%) had information available regarding the clinical grade of disease from the preoperative endoscopic biopsy. The distribution was grade 1 in 2 (1.6%), grade 2 in 46 (38.7%), and grade 3 in 71 (59.7%) patients. Of the 71 patients with grade 3 disease, 47 had Stage pT2 disease or higher (66% positive predictive value). Of the 48 patients with less than grade 3 disease, 35 had less than pT2 disease (72% negative predictive value). Of the 71 patients with grade 3 disease, 30 had pT3 disease or greater (42% positive predictive value), and of the 48 patients with less than grade 3 disease, 44 had less than pT3 disease (92% negative predictive value). CONCLUSIONS The histologic grade obtained from the diagnostic biopsy for upper urinary tract transitional cell carcinoma can be used to predict the pathologic disease stage. This information can be used to counsel patients before surgery and to identify patients for whom neoadjuvant chemotherapy would be most beneficial. |
