INTRODUCTION: Lymph node dissection (LND) performed during radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC) remains controversial and difficult to evaluate. The aim of this study was to investigate whether removal of more lymph nodes during RNU is safe and improves oncologic outcomes. METHODS: We evaluated 422 patients who underwent RNU with concomitant LND for upper tract urothelial carcinoma between 1976 and 2015, assessing for an association between total nodes removed, recurrence-free survival, and cancer-specific survival using Cox proportional hazards models...

OBJECTIVE: Unlike for bladder cancer, the impact of regional lymph node dissection for upper tract urothelial carcinoma is unclear. We explored whether patient survival was influenced by systematic regional lymph node dissection, using resection templates according to the main tumor location, during radical nephroureterectomy for upper tract urothelial carcinoma. METHODS: The systematic regional lymph node dissection group was defined as cases in which the dissection of nodes and surrounding tissues followed the established template, and the non-systematic regional lymph node dissection group as cases undergoing limited or no lymph node dissection...

: Given the growing body of evidence supporting the benefit of primary tumor control for a wide range of metastatic malignancies, we hypothesized that chemotherapy plus radical nephroureterectomy (RNU) is associated with an overall survival (OS) benefit compared to chemotherapy alone for metastatic upper tract urothelial carcinoma (mUTUC). Within the National Cancer Data Base (2004-2012), we identified 398 (38.4%) and 637 (61.6%) patients who received chemotherapy plus RNU and chemotherapy alone, respectively...

There is relatively little literature on adjuvant radiotherapy after radical nephroureterectomy with bladder cuff excision (RNU) for patients with upper tract urothelial carcinoma (UTUC). This study was designed to determine the efficacy of adjuvant radiotherapy for patients with pT3N0M0 UTUC. We retrospectively reviewed 198 patients treated with RNU between December 2001 and January 2015. Postoperative radiotherapy was administered in 40 (20.2%) of patients. Patients who received radiotherapy were younger than those that did not (65...

INTRODUCTION: Urological dogma dictates that washings collected from the urinary tract for cytological assessment must be performed without interference from contrast agents that may alter cellular integrity and diagnostic interpretation. In practice, the initial contrast used to outline the upper tracts is commonly discarded with subsequent saline washings sent for cytology. We hypothesize that contrast washings do not affect the morphology of urothelial carcinoma cells or the integrity of cytology interpretation...

OBJECTIVE: The presence of atypical cells in urine cytology is unsatisfactory for both cytologists and clinicians. The objective of this study was to test whether p53 and Ki-67 immunostaining could improve urothelial carcinoma (UC) detection on urinary cytology. METHODS: A total of 196 urine samples were analysed, 142 from the bladder, 41 from the upper tract and 13 from ileal bladder replacement. Cytology results were expressed as normal (N) (n = 81), atypia cannot exclude low-grade UC (ALG) (n = 25), suspicious for high-grade UC (SHG) (n = 39) and high-grade UC (HG) (n = 51)...

BACKGROUND: To date, prophylactic intravesical chemotherapy after radical nephroureterectomy is one of the few available treatments that effectively prevent secondary bladder cancer. However, treating all patients with prophylactic intravesical chemotherapy is excessive for patients who are at a low risk or insensitive to the treatment. Thus, to guide individualized clinical treatment, in addition to identifying patients who are at risk of bladder cancer recurrence, it is equally necessary to identify the patients who will benefit the most from prophylactic, postoperative intravesical instillation therapy...

We present an unusual pediatric case of invasive upper tract urothelial carcinoma with an associated genetic predisposition. A 14 year-old female presented with intermittent right flank pain, and was found to have a poorly functioning hydronephrotic right kidney. Laparoscopic nephrectomy was performed. Pathology demonstrated upper tract urothelial carcinoma, and she subsequently underwent completion ureterectomy. Genetic studies demonstrated a double-hit constitutional deletion of a DNA mismatch repair protein, revealing a rare Lynch syndrome variant known as Constitutional Mismatch Repair Deficiency Syndrome (CMMRD)...
