Abstract
Purpose:. According to the National Comprehensive Cancer Network guidelines, segmental ureterectomy (SU) of upper tract urothelial carcinoma (UTUC) is a considerable option for selected mid- and distal ureteral urothelial carcinoma (UC). As a UTUC endemic area, Taiwan lacks treatment outcome analysis of SU. Materials and methods:. This study retrospectively reviewed the treatment outcomes of SU for clinically localized UTUCs. Patients with biopsy or washing cytology-confirmed UTUCs who underwent open, laparoscopic, or robot-assisted management with curative intent were retrospectively reviewed for the eligibility of analysis. Cox regression was applied for univariable and multivariable analyses. Results:. A total of 161 patients who underwent SU were reviewed and analyzed. The median follow-up period was 44.5 (interquartile range, 21.6–84.9) months. After SU, 56/161 (34.8%) patients were free of UTUCs after the follow-up, 25/161 (15.5%) patients had local recurrence, and 35/161 (21.7%) had lymph node or distant metastasis. Surgical margin involvement was a risk factor associated with worse cancer-specific survival. Higher bladder recurrence and local recurrence rates were observed with concurrent bladder UC. Lymphovascular invasion and previous radical nephroureterectomy (RNU) for UC were related to higher local recurrence rates. Patients with pathological T3/T4 stage and end-stage renal disease tended to have higher metastasis rates. For the management of local recurrence, 19 patients received salvage RNU and 25 patients had adjuvant chemotherapy. However, 26/161 (16.1%) patients died of UTUCs and 2/161 (1.2%) patients died of surgery-related complications. Conclusion:. SU provides acceptable oncological outcomes if the surgeons select candidates carefully. SU is not recommended if the patient has T3 or higher stage or comorbidity of end-stage renal disease. Concurrent bladder UC is a risk factor for worse bladder recurrence-free survival and local recurrence-free survival. Lymphovascular invasion and previous RNU for UC were related to higher local recurrence rates. After SU, periodic follow-up is mandatory because the local recurrence rate is higher than radical surgery.
