BACKGROUND: We examined the long-term outcome and compared the usefulness of nephroureterectomy with that of bacillus Calmette-Guérin (BCG) therapy for the management of upper urinary tract carcinoma in situ (CIS). METHODS: We retrospectively reviewed the post-treatment course of 17 patients with CIS of the upper urinary tract who had undergone either a nephroureterectomy (group A, n = 6) or BCG therapy (group B, n = 11) at our institute. RESULTS: Median follow up was 58.3 months (range 1-120 months). Four of the six patients in group A (67%) had no recurrence and remained cystoscopically, cytologically and radiographically free of disease. The cytology became negative after an 8-week course in nine of the eleven patients in group B (82%; eight of ten units, 77%). Two of the nine patients showed recurrence after BCG therapy. One patient died of respiratory failure caused by a side-effect of BCG, which was interstitial pneumonia. There was no significant difference in either the 5-year recurrence-free survival or the 5-year cancer-specific survival between groups A and B. CONCLUSIONS: BCG therapy for CIS of the upper urinary tract is as effective as nephroureterectomy in long-term outcome, although it has some dangerous aspects. Further experience with treatment of CIS of the upper urinary tract is required.
