Abstract
PURPOSE To review the latest evidence on the modern techniques and outcomes of kidney-sparing surgeries (KSS) in patients with upper tract urothelial carcinoma (UTUC). METHODS A comprehensive literature search on the study topic was conducted before 30 April 2023 using electronic databases including PubMed, MEDLINE, and EMBASE. A narrative overview of the literature was then provided based on the extracted data and a qualitative synthesis of the findings. RESULTS KSS is recommended for low- as well as select high-risk UTUCs who are not eligible for radical treatments. Endoscopic ablation is a KSS option that is associated with similar oncological outcomes compared with radical treatments while preserving renal function in well-selected patients. The other option in this setting is distal ureterectomy, which has the advantage of providing a definitive pathological stage and grade. Data from retrospective studies support the superiority of this approach over radical treatment with similar oncological outcomes, albeit in select cases. Novel chemoablation agents have also been studied in the past few years, of which mitomycin gel has received FDA approval for use in low-risk UTUCs. CONCLUSION KSSs are acceptable approaches for patients with low- and select high-risk UTUCs, which preserve renal function without compromising the oncological outcomes.

Endoscopic management of upper tract urothelial cancer in a highly endemic area: A Taiwan nationwide collaborative study. Asian J Surg 2023; 46:3058-3065. [PMID: 37525448 DOI: 10.1016/j.asjsur.2022.10.046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 06/25/2022] [Accepted: 10/13/2022] [Indexed: 11/02/2022] Open
Abstract
BACKGROUND Endoscopic management of upper tract urothelial cancer (UTUC) is an important treatment option for low risk UTUC. Although Taiwan is an endemic area for UTUC, endoscopic treatment outcomes in Taiwan are frequently under- reported. METHODS This study retrospectively reviewed the treatment outcomes of endoscopic management for clinically localized UTUC. Patients with biopsy or washing cytology confirmed UTUC who underwent endoscopic or percutaneous management with a curative intent were retrospectively reviewed for eligibility of analysis. Those cases without pre-intervention confirmed UTUC, and metastatic or nodal disease at diagnosis were excluded. RESULTS In total, 307 patients who underwent endoscopic management were reviewed and 279 cases were eligible for final analysis. With a median follow-up of 44.3 months (inter-quartile range (IQR): 23.4-76.4 months), 117 cases (46.4%) were endoscopic cured after median one session (range:1-8; IQR:1-2) of endoscopic treatment. Those endoscopic cured UTUC was associated with more small-sized tumor, more low-grade biopsied-histology, less concomitant bladder UC and less pre-operative hydronephrosis. In addition, 201(79.7%) cases among 252 cases with confirmed oncological outcome were free of UTUC at the end of follow-up and only 43 (17%) patients had a UTUC related mortality. Salvage RNU offered a better tumor free survival rate (92% vs. 77.5%) than those without salvage RNU in those UTUC refractory to endoscopic management. In multivariable analyses, pre-operative hydronephrosis was the independent risk factor for OS. Multiplicity and concomitant bladder UC were independent risk factors for DFS. CONCLUSIONS We confirmed the consistent safety and efficacy of endoscopic management of clinical localized UTUC in a highly UTUC endemic area like Taiwan. Early salvage RNU is mandatory in those UTUC refractory to endoscopic management in prevention of UTUC related death.
