Abstract
BACKGROUND
The efficacy and longโterm results of endoscopic management of upper tract transitional cell carcinoma (TCC) were examined. The authors evaluated the accuracy of endoscopic biopsy in determining tumor grade in the subset of patients who underwent open surgical excision.
METHODS
Between 1987 and 2001, 50 patients (17 with a solitary kidney) underwent ureteroscopy and biopsy of upper tract TCC. Eleven patients underwent ureterectomy or nephroureterectomy shortly after endoscopic biopsy. There was no followโup for nine patients. Thirty patients underwent endoscopic ablation of their primary tumor with laser or electrofulguration at the time of the initial biopsy and were followed with close endoscopic surveillance at 3โ4โmonth intervals.
RESULTS
For the 30 patients who underwent endoscopic ablation, mean followโup was 38 months (range, 4โ106 months). There was an average of 3.4 recurrences, with an average time to first recurrence of 7 months. Ten of the 30 patients underwent open resection during followโup. Six patients exhibited tumor progression at followโup. During the followโup period, one patient died of recurrent disease, and six died of other causes. Endoscopic biopsy accurately predicted the tumor grade for 8 of the 9 patients who had open tumor resection within 2 months of their last biopsy and for 10 of the 11 patients who had open resection shortly after their initial endoscopic biopsy (overall accuracy, 18 of 20 [90%]).
CONCLUSIONS
Endoscopic treatment of focal lowโgrade TCC of the upper urinary tract is feasible and safe, provided that vigilant followโup and endoscopic surveillance are performed. Endoscopic biopsy provides accurate information regarding tumor grade. Cancer 2003;98:55โ60. ยฉ 2003 American Cancer Society.
