Oncologic results of nephron sparing endoscopic approach for upper tract low grade transitional cell carcinoma in comparison to nephroureterectomy, "Beyond the Abstract," by Azik Hoffman

BERKELEY, CA (UroToday.com) - Our article discusses an issue of great interest among urologists and oncologists. Upper tract TCC still remains a relatively rare disease. Among those patients, the presence of low-grade upper tract TCC is even more rare, making it more difficult to evaluate the best management and treatment options. Therefore, there is a paucity of data regarding optimal treatment and follow-up protocols in such cases.

Although no real head-to-head prospective trials have been conducted, a conservative nephron-sparing approach has been considered the new standard of care in low-grade upper tract TCC. The main concerns in practicing it is missing a concurrent high-grade upper tract TCC (either by transitional endothelial field changes or by TCC upstaging), followed by increased low-grade TCC recurrence rate.

We suggest a strict patient selection: endourological procedure without concurrent nephroureterectomy, selected when there is a small tumor burden (up to 1.5 cm for a single lesion and the ability for a complete resection of all lesions), and the ability of the urologist and the patient to adhere to a strict follow-up protocol.

In our opinion, adhering to the protocol presented in the article allows kidney function preservation while minimizing morbidity and mortality. However, a demanding follow-up protocol has its price – relatively frequent upper tract imaging and possibly the need for frequent bladder and upper tract endourological procedures should be taken into consideration when choosing nephron-sparing option for treating low-grade upper tract TCC.
