ABSTRACT
We sought to examine the effect of tumor location on the prognosis of patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU). This retrospective study came from the Taiwan UTUC Collaboration Group, which consisted of 2658 patients at 15 institutions in Taiwan from 1988 to 2019. Patients with kidney-sparing management, both renal pelvic and ureteral tumors, as well as patients lacking complete data were excluded; the remaining 1436 patients were divided into two groups renal pelvic tumor (RPT) and ureteral tumor (UT), with 842 and 594 patients, respectively. RPT was associated with more aggressive pathological features, including higher pathological T stage (p < 0.001) and the presence of lymphovascular invasion (p = 0.002), whereas patients with UT often had synchronous bladder tumor (p < 0.001), and were more likely to bear multiple lesions (p = 0.001). Our multivariate analysis revealed that UT was a worse prognostic factor compared with RPT (overall survival HR 1.408, 95% CI 1.121-1.767, p = 0.003; cancer-specific survival HR 1.562, 95% CI 1.169-2.085, p = 0.003; disease-free survival HR 1.363, 95% CI 1.095-1.697, p = 0.006; bladder-recurrence-free survival HR 1.411, 95% CI 1.141-1.747, p = 0.002, respectively). Based on our findings, UT appeared to be more malignant and had a worse prognosis than RPT.
