Preoperative and postoperative CT staging of XXXX .

@entity1 @entity189
This study reports a 4 year experience using CT for preoperative staging and for evaluation of @entity1 with @entity189 after surgery. All @entity1 were evaluated on a GE 8800 scanner using 1 cm contiguous slices. Only 15 of the 25 preoperative @entity1 were staged correctly. The other 10 @entity1 were understaged by CT. The accuracy of detecting local invasion was 70%, but only seven (35%) of 20 @entity1 had accurate assessment of lymph nodes. The overall accuracy of CT staging in the 46 postoperative @entity1 was 87%, with a sensitivity of 91% and a specificity of 72%. Most recurrences were found in the pelvis; 16 @entity1 had liver metastases, and metastatic disease obstructing the ureters was detected in eight @entity1 . On the basis of these results, it was concluded that CT should not be used routinely to preoperatively stage @entity1 with @entity189 . However, all @entity1 who have undergone resection for @entity189 should have aggressive CT evaluation including a baseline study at 2-4 months and then follow-up studies at every 6 months for at least 2 years. All new or enlarging masses should have CT-guided biopsies. This approach may prolong survival by detecting early asymptomatic recurrences.
