BACKGROUND: Tumour recurrences are frequent among patients with upper tract urothelial carcinoma (UTUC) treated with ureteroscopy (URS). Therefore, guidelines recommend a strict follow-up regimen, but there is little evidence on how to do this.
OBJECTIVE: To analyse outcomes during our follow-up regimen and the impact on treatment in terms of ipsilateral UTUC recurrence, treatment conversion, and tumour upgrading, and to evaluate potential prognostic factors, including second-look URS outcomes. A secondary objective was to evaluate survival outcomes.
DESIGN, SETTING, AND PARTICIPANTS: The single-centre cohort included all adult patients with nonmetastatic UTUC treated with URS from January 2010 to December 2020. Follow-up involved endoscopy at 3-mo intervals in the first year, then at 6-mo intervals up to year 3, and yearly thereafter.
OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Descriptive analyses were performed for the follow-up outcomes. The Andersen-Gill model for recurrent event analysis was used to analyse tumour recurrences, and multivariable Cox regression to analyse for predictors for treatment conversion in low-grade tumours.
RESULTS AND LIMITATIONS: We analysed 71 patients with median follow-up of 49.5 mo. The overall 2-yr recurrence-free survival (RFS) rate was 22%. In low-grade disease, the 1-yr RFS rate was 50% and the 2-yr RFS rate was 29%. Treatment was converted to radical nephroureterectomy for 23 patients, at a median time to conversion of 9.9 mo. Upgrading was seen in 13 patients, at a median time to upgrading of 21.9 mo. No factors were prognostic for either tumour recurrence or treatment conversion. The 5-yr OS, CSS, and MFS rates were 82%, 86%, and 84%, respectively.
CONCLUSIONS: Our data show that it is rational to extend endoscopic follow-up for UTUC treated with URS, as clinically relevant events (treatment conversion and tumour upgrading) occur beyond the current 6-mo guideline recommendation. Second-look URS outcomes were not prognostic for tumour recurrence or treatment conversion during follow-up.
PATIENT SUMMARY: Our study results show that for patients with cancer of the upper urinary tract treated with kidney-sparing surgery through a small telescope called a ureteroscope (URS), most of the clinically relevant events (treatment conversion and tumour upgrading) occur outside the current recommended follow-up of 6 months. Therefore, URS follow-up should be extended for these patients.
