Using preclinical models, we have recently found that ELK1, a transcriptional factor that activates downstream targets, including c-fos proto-oncogene, induces bladder cancer outgrowth. Here, we immunohistochemically determined the expression status of phospho-ELK1, an activated form of ELK1, in upper urinary tract urothelial carcinoma (UUTUC). Overall, phospho-ELK1 was positive in 47 (47.5%; 37 weak (1+) and 10 moderate (2+)) of 99 UUTUCs, which was significantly ( P = 0.002) higher than in benign urothelium (21 (25...

The clinical benefits of bacillus Calmette-Guérin (BCG) therapy for the management of upper urinary tract carcinoma in situ (CIS) remain unclear. We aimed to compare the efficacy and safety of BCG therapy for upper urinary tract CIS with those of radical nephroureterectomy (RNU). Of 490 patients with upper urinary tract carcinoma, we retrospectively reviewed the post-treatment course of 58 patients with upper urinary tract CIS who underwent either RNU (RNU group) or BCG therapy (BCG group). Efficacy and safety were compared between the RNU and BCG groups...

The aging population is becoming a primary global problem. The most important alteration that occurs in the body with age, is the loss of skeletal muscle. Previously, sarcopenia, which is associated with the loss of skeletal muscle, has been reported to be associated with the prognosis of cancer and complications. The present study investigated the importance of sarcopenia with regard to the prognosis or postoperative complications of upper urothelial cancer patients who underwent nephro-ureterectomy. A total of sixty patients (male, n=44; female, n=16) underwent nephro-ureterectomy for upper urothelial carcinoma...

BACKGROUND Plasmacytoid is a rare histological variant of urothelial carcinoma (UC). Since the first reported case of plasmacytoid urothelial carcinoma (PUC), in 1991, only about 100 cases have since been reported, with most cases involving the bladder. Urothelial carcinomas of the upper urinary tract represent only 5% of urothelial cancers. To the best of our knowledge, there has only been 1 reported case of PUC of the ureter. PUC is a highly aggressive disease, with a poor prognosis. We present a rare biopsy-proven case of PUC of the ureter with retroperitoneal metastasis...

We report a case of a highly advanced urothelial carcinoma accompanied by duodenal stenosis with pancreaticoduodenectomy. A6 6-year-old man presented with upper abdominal pain and vomiting. Acute pancreatitis and hydronephrosis were diagnosed with urgent hospitalization, but jaundice appeared, and stenosis of the duodenum was also found. Thus, we suspected groove pancreatitis or pancreatic cancer, and performed pancreaticoduodenectomy. However, poorly differentiated adenocarcinoma was observed in the retroperitoneal dissection surface in the intraoperative rapid tissue and right hemicolectomy, right nephrectomy, and right ureteral resection were added to the diagnosis...

INTRODUCTION: Conservative management of upper tract urothelial cancer (UTUC) is becoming increasingly popular: the key to success is correct selection of patients with low-risk UTUC based on size (≤ 2 cm), focality (single lesion), stage (< T2), and grade (low grade). Despite the recent growing interest in the conservative approach to UTUC, the diagnostic process is still a challenge, and kidney-sparing surgery (KSS) is traditionally reserved for patients with contraindications to radical nephroureterectomy...

INTRODUCTION: The number of patients on chronic anticoagulant or antiplatelet therapy requiring endoscopic urological surgery is increasing worldwide. Therefore, there is a strong demand to standardize the peri-operative treatment of this cohort of patients, both from a surgical and cardiological point of view, balancing the risks of bleeding versus thrombosis, and the important possible clinical and medical legal repercussions therein. EVIDENCE ACQUISITION: Although literature is scarce and the quality of evidence quite low, in line with other surgical specialties, guidelines and recommendations for the management of urological patients have begun to emerge...

Urinary diversion has been in the scope of practice of Gynecologic Oncologists since the inception of the sub-specialty. However, many fewer urinary diversions are performed currently than in the past due to improved prevention of cervical cancer. The intent of this article is to provide a state of the art review for Gynecologic Oncologists. Surgeons performing these complex procedures must be knowledgeable about the differences between various types of continent and non-continent urinary diversions, and the principles of pre and post-operative care...
