Tumor budding in upper urinary tract urothelial carcinoma: a putative prognostic factor for extraurothelial recurrence and overall survival.

Virchows Arch 2021 Jan 6. Epub 2021 Jan 6.

Department of Urology, National Defense Medical College, Tokorozawa, Saitama, Japan.

Tumor budding, defined as a single cancer cell or clusters of fewer than five cancer cells observed at the tumor invasion front, has been reported to be associated with poor prognosis in various types of cancers. However, limited information regarding the pathological and prognostic significance of tumor budding in upper urinary tract urothelial carcinoma (UUTUC) is available. We investigated 135 consecutive patients with newly diagnosed invasive UUTUCs (73 with renal pelvic cancers and 62 with ureteral cancers) treated with nephroureterectomy or partial ureterectomy between 1999 and 2018 in our hospital.

Urinary Tract Resections as Part of Debulking Surgery for Locally Advanced Endometrial Stromal Sarcomas.

In Vivo 2020 Mar-Apr;34(2):793-797

"Carol Davila" University of Medicine and Pharmacy, Bucharest, Romania.

Background/aim: Although very rare tumors, uterine sarcomas are extremely aggressive gynecologic malignancies being responsible for a significant number of gynecological cancer-related deaths. However, in such cases, it seems that cytoreductive surgery might increase the lifespan if debulking to no residual disease is achieved.

Patients And Methods: We present a case series of three patients diagnosed with endometrial stromal sarcomas in which urinary tract resections were needed in order to maximize the debulking effort. Read More

Modified posterior pelvic exenteration with pelvic side-wall resection requiring both intestinal and urinary reconstruction during surgery for ovarian cancer.

Gynecol Oncol 2019 10 25;155(1):172-173. Epub 2019 Jul 25.

Department of Gynecology, Cancer Institute Hospital, 3-8-31 Ariake, Koutou-ku, Tokyo 135-8550, Japan.

Objective: Because of the anatomic proximity of the rectosigmoid to the female pelvic organs and its frequent involvement in ovarian cancer, an en bloc resection of ovarian tumors together with the uterus and rectosigmoid, also known as a modified posterior pelvic exenteration (MPPE), is frequently performed to achieve optimal cytoreduction [1]. Additionally, if the tumor has infiltrated the pelvic side-wall, a MPPE combined with pelvic side-wall resection can be selected [2]. We report the details of a technique for this surgery requiring intestinal and urinary reconstruction. Read More

Duplex System with Ectopic Ureter Opens into the Posterior Urethra: Case Report.

Med Arch 2018 Apr;72(2):145-147

Hospital for Surgical and Internal Medicine S.tetik, Banja Luka, Bosnia and Herzegovina.

Introduction: Duplicated ureter or Duplex Collecting System is a congenital condition in which the ureteric bud, the embryological origin of the ureter, arises twice, resulting in two ureters draining a single kidney. This congenital anomaly is rare, and even rarer when the duplex system with ectopic ureter is present. This type of congenital anomaly is even more rarely diagnosed and surgically treated in adulthood. Read More

Reduce bladder cancer recurrence in patients treated for upper urinary tract urothelial carcinoma: The REBACARE-trial.

Contemp Clin Trials Commun 2018 Mar 28;9:121-129. Epub 2018 Feb 28.

Erasmus University Medical Center, Rotterdam, The Netherlands.

Background: Following radical nephro-ureterectomy for urothelial carcinoma of the upper urinary tract (UUT), the reported bladder recurrence rate of urothelial carcinoma is 22-47%. A single intravesical instillation of chemotherapy within 10 days following nephro-ureterectomy has the potential to decrease the risk of a bladder recurrence significantly. Despite recommendation by the European Association of Urology guideline to administer a single instillation postoperatively, the compliance rate is low because the risk of extravasation of chemotherapy.

Upper tract urothelial carcinoma: special considerations.

Clin Adv Hematol Oncol 2016 Feb;14(2):101-9

University of Texas, Southwestern Medical Center, Dallas, Texas.

Upper tract urothelial carcinoma (UTUC) is an uncommon disease with a prognosis worse than that of primary urothelial carcinoma (UC) of the bladder. Although surgery remains the mainstay of UTUC therapy, there is increasing enthusiasm for combined-modality approaches in both adjuvant and neoadjuvant settings. Nephron-sparing surgical strategies, including partial ureterectomy and purely endoscopic tumor resection, are also increasingly used. Read More
