Incidence of upper tract urothelial carcinoma in Spain.

Abstract：

INTRODUCTION AND OBJECTIVES:The incidence of upper urinary tract tumors is currently unknown. The aim of this study is to determine the real incidence of upper tract urothelial carcinoma (UTUC) in Spain. MATERIAL AND METHODS:A descriptive, prospective and multicenter epidemiological study was conducted in 31 Spanish facilities by means of the Platform for Multicenter Studies of the Spanish Association of Urology. Recruitment was opened from May 1st, 2017 to April 30th, 2018. The original database was exported directly from the electronic Data Collection Logbook on December 15th, 2018, with a total of 404 cases registered (402 valid cases after depuration). Statistical analysis was performed using IBM SPSS software v 23 and EPIDAT v 3.4. RESULTS:The incidence adjusted to Spanish population from raw data was 3.27 cases per 100.000 inhabitants per year (2.93 - 3.61 95% CI) and 3,3 cases per 100.000 inhabitants per year (2.96-3.66 95%CI) when adjusted to European population by age. The mean age at diagnosis was 70 years, and 77% of patients were male. Thirty-four percent of patients had an incidental diagnosis. Tumors were most commonly located in the pyelocalyceal system (54%), followed by the distal ureter (22%). Prior ureteroscopy was performed in 114 patients: this technique modified the subsequent treatment indication in 58% of cases. Radical nephroureterectomy was performed in 311 patients. Kidney-sparing surgery was the elected treatment in 76 patients (20%). Complications were found in 69% of cases, most of them classified as Clavien 1 and 2 (86% of all complications). Postoperative mortality rate was 1.7%. CONCLUSIONS:UTUC adjusted incidence rate in Spain is 3.27 and 3.3 in Europe. Prior URS modified the treatment indication in 18% of patients. We found a 69% complication rate and a 1.7% mortality rate.
