“…Some investigators have suggested that select patients, in particular those with low grade, low-stage (pT1 or less) disease and a normal contralateral kidney, could be managed with nephron-sparing procedures because they have very good outcomes. 4,[40][41][42][43] The 1998 grading system may be quite useful in these circumstances, as it appears to more clearly separate low-from high-grade tumors, and shows that lowgrade tumors are associated with a low risk of invasion.…”

Impact of the 1998 World Health Organization/International Society of Urological Pathology classification system for urothelial neoplasms of the kidney

The classification of urothelial neoplasms of the kidney traditionally has been similar to that of urinary bladder tumors. Several years ago, the classification of papillary urothelial neoplasms was revised. The current study focuses on the application of the 1998 World Health Organization (WHO)/International Society of Urological Pathology classification system to 102 renal pelvic urothelial neoplasms and compares it to the 1973 WHO classification scheme. In this study, all tumors were classified as urothelial carcinomas, and the majority (85%) were papillary. Most patients with papillary tumors presented with 'superficial' disease (rpT1). With the 1998 system, most papillary carcinomas were high grade, and were more often invasive as compared to low-grade tumors. Only 34% were low-grade papillary tumors and, of these, most (93%) were noninvasive. With the 1973 system, most papillary tumors were grade 2 or 3, with invasion more common in grade 3 tumors. By 1973 criteria, grade 2 tumors were a heterogeneous group; with 1998 criteria, nearly one-half were high grade and the other half low grade. The grade of papillary urothelial carcinomas with both the 1973 and 1998 grading methods was associated with stage (P ¼ 0.001). Our study reveals that papillomas and papillary urothelial neoplasms of low malignant potential are uncommon tumors in the kidney. Renal pelvic papillary urothelial neoplasms are most often carcinomas and are more commonly high grade than low grade. Although both the 1973 and 1998 systems showed a significant association with tumor stage, grade 2 papillary carcinomas are a heterogeneous group by 1973 criteria. The 1998 system provides useful information in that it more clearly defines a papillary tumor's grade and selects for a group of tumors, namely low-grade papillary urothelial carcinomas, for which a low likelihood of invasion can be predicted.

“…4,5 Deligne et al 6 reported on 61 patients managed endoscopically, 20 with a solitary kidney, and found at 39.9 months that the rate of kidney preservation was 81%, the recurrence-free rate was 68%, global survival was 77%, and specific survival was 84%. Again, we found similar results at 33 months, with a kidney preservation rate of 80%, a recurrence-free rate of 60%, global survival of 70%, and TCC-specific survival of 70%.…”

Renal-sparing approaches remain an option in motivated patients with solitary kidneys and UT-TCC. Patients should realize that management tends to involve multiple procedures that are associated with potential morbidity, entails lifetime follow-up, and often requires long-term nephrostomy access for topical treatment or relief of obstruction. Long-term patient quality-of-life and cancer-specific outcomes for renal- sparing management compared with quality-of-life and survival on dialysis are unknown.

“…43 Similarly, among 60 patients with a mean followup of 51 months, disease-specific survival for patients with grades 1, 2, and 3 tumours was 100%, 94%, and 62%, respectively. 54 Additionally, tumour stage and multifocality correlate with recurrence after nephron-sparing procedures. 44,47,52,56 Due to a lack of adequately powered studies, additional prognostic factors following nephron-sparing procedures are presently unknown.…”
