Robotic nephroureterectomy in a horseshoe kidney for upper tract urothelial carcinoma.

BMJ Case Rep 2021 Jun 9;14(6). Epub 2021 Jun 9.

Urology, East Kent Hospitals University NHS Foundation Trust, Canterbury, UK.

Upper tract urothelial carcinoma represents a small proportion (5%-10%) of all urothelial cancers. Although there are several management options, in undifferentiated or high-risk cases, surgery in the form of nephroureterectomy is the gold standard. Horseshoe kidney is the most common congenital renal fusion anomaly affecting 1 in 400-600 patients. Read More

Upper tract transitional cell carcinoma clinically mimicking inflammatory renal pathology: A report of three cases.

Indian J Urol 2021 Apr-Jun;37(2):169-172. Epub 2021 Apr 1.

Department of Urology and Renal Transplant, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, Uttar Pradesh, India.

Upper tract urothelial carcinoma (UTUC) of the renal pelvis and the ureter is incidentally detected in a small proportion of cases. However, the majority of UTUC cases present with hematuria, flank pain, and clot colic. Typical imaging features include hydronephrosis of the kidney (s) due to obstruction by the mass with a soft-tissue lesion that typically shows low-grade enhancement with or without a filling defect.

ACR Appropriateness Criteria® Post-Treatment Surveillance of Bladder Cancer: 2021 Update.

J Am Coll Radiol 2021 May;18(5S):S126-S138

Specialty Chair, University of Alabama at Birmingham, Birmingham, Alabama.

Urothelial cancer is the second most common cancer, and cause of cancer death, related to the genitourinary tract. The goals of surveillance imaging after the treatment of urothelial cancer of the urinary bladder are to detect new or previously undetected urothelial tumors, to identify metastatic disease, and to evaluate for complications of therapy. For surveillance, patients can be stratified into one of three groups: 1) nonmuscle invasive bladder cancer with no symptoms or additional risk factors; 2) nonmuscle invasive bladder cancer with symptoms or additional risk factors; and 3) muscle invasive bladder cancer.

Pathologically diagnosed incidentaloma transition cell carcinoma (TCC) of renal pelvis in a laproscopic radical nephrectomy specimen done for a lower pole renal mass.

Urol Case Rep 2021 Jul 11;37:101607. Epub 2021 Feb 11.

Apollo Hospitals, Indore, India.

We are reporting a very rare case in the current era of modern diagnostics of an incidentally detected Transitional Cell Carcinoma(TCC) renal pelvis, detected pathologically when Right laparoscopic radical nephrectomy specimen of lower pole mass(RCC) was processed, with no prior suspicion of TCC clinically or pre-operative imaging. A 75-year-old female with 4 × 4cm strongly enhancing lower pole renal mass on CTscan underwent a Laparoscopic Radical Nephrectomy. Surprisingly histopathological examination revealed a focus of low-grade TCC, arising from renal pelvis, completely separate from lower pole mass which was a clear cell RCC. Read More

Staging F-fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Changes Treatment Recommendation in Invasive Bladder Cancer.

Eur Urol Oncol 2021 Feb 11. Epub 2021 Feb 11.

Department of Urology, The Netherlands Cancer Institute-Antoni van Leeuwenhoek Hospital, Amsterdam, The Netherlands. Electronic address:

Given the high risk of systemic relapse following initial therapy for muscle-invasive bladder cancer (MIBC), improved pretreatment staging is needed. We evaluated the incremental value of F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) after standard conventional staging, in the largest cohort of MIBC patients to date. This is a retrospective analysis of 711 consecutive patients with invasive urothelial bladder cancer who underwent staging contrast-enhanced CT (chest and abdomen) and FDG-PET/CT in a tertiary referral center between 2011 and 2020.

Right Renal Pelvis Renal Cell Carcinoma Mimicking Transitional Cell Carcinoma: Case Report.

J Endourol Case Rep 2020 29;6(4):536-539. Epub 2020 Dec 29.

Department of Urology, Hackensack University Medical Center, Hackensack, New Jersey, USA.

Renal cell carcinoma (RCC) originates from the renal parenchyma, whereas transitional cell carcinoma (TCC) originates from the renal urothelium. Although renal pelvis TCC is relatively rare in terms of urologic malignancies, it is the most common tumor originating in renal pelvis. A 75-year-old woman presented with gross hematuria found to have a filling defect in the renal pelvis with retrograde pyelogram and cytology showed clusters of urothelial cells, with imaging suspicious for TCC.

Imaging Characterization of Renal Masses.

Medicina (Kaunas) 2021 Jan 8;57(1). Epub 2021 Jan 8.

Radiology Department, Hospital Clinic, University of Barcelona (UB), 08036 Barcelona, Spain.

The detection of a renal mass is a relatively frequent occurrence in the daily practice of any Radiology Department. The diagnostic approaches depend on whether the lesion is cystic or solid. Cystic lesions can be managed using the Bosniak classification, while management of solid lesions depends on whether the lesion is well-defined or infiltrative. Read More

Phase II study of the histone deacetylase inhibitor vorinostat (Suberoylanilide Hydroxamic Acid; SAHA) in recurrent or metastatic transitional cell carcinoma of the urothelium - an NCI-CTEP sponsored: California Cancer Consortium trial, NCI 6879.

Invest New Drugs 2021 Jun 6;39(3):812-820. Epub 2021 Jan 6.

City of Hope Comprehensive Cancer Center, Duarte, CA, USA.

Background: Until the advent of T cell check point inhibitors standard second-line therapy for patients with metastatic urothelial cancer (mUC) was undefined. Histone deacetylase inhibitors (HDACi) have anti-cancer activity in a variety of tumor models including modulation of apoptosis in bladder cancer cell lines. We evaluated the efficacy and toxicity of the HDACi vorinostat in patients with mUC failing first-line platinum-based therapy either in the adjuvant/neoadjuvant setting or for recurrent/advanced disease.

CT Urography Findings of Upper Urinary Tract Carcinoma and Its Mimickers: A Pictorial Review.

Medicina (Kaunas) 2020 Dec 17;56(12). Epub 2020 Dec 17.

Department of Radiology, University of Trieste, ASUGI, Cattinara Hospital, 34139 Trieste, Italy.

Urothelial carcinoma (UC) is the fourth most frequent tumor in Western countries and upper tract urothelial carcinoma (UTUC), affecting pyelocaliceal cavities and ureter, accounts for 5-10% of all UCs. Computed tomography urography (CTU) is now considered the imaging modality of choice for diagnosis and staging of UTUC, guiding disease management. Although its specificity is very high, both benign and malignant diseases could mimic UTUCs and therefore have to be well-known to avoid misdiagnosis. Read More

Acquired Cystic Disease-Associated Renal Cell Carcinoma Extending to the Renal Pelvis Mimicking Urothelial Carcinoma on Computed Tomography (CT): Two Case Reports.

Am J Case Rep 2020 Oct 19;21:e926630. Epub 2020 Oct 19.

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

BACKGROUND Acquired cystic disease-associated renal cell carcinoma (ACD-associated RCC), which was added to the 2016 World Health Organization classification, is the most common subtype of RCC in patients undergoing long-term dialysis. ACD-associated RCC is underrecognized and reports of computed tomography (CT) and magnetic resonance imaging findings for the lesion are sparse. Similar to urothelial carcinoma, ACD-associated RCC is poorly to slightly enhanced on dynamic CT. Read More

J Vet Med Sci 2021 Apr 22;83(4):695-704. Epub 2020 Sep 22.

"La Cittadina" Foundation for Veterinary Studies and Research, Road to the "La cittadina", 26014, Romanengo (Cr), Italy.

The aims of this pilot study were to evaluate the feasibility and efficacy of high-dose hypofractionated volumetric modulated arc radiotherapy (VMAT) applied to whole pelvic region radiotherapy (WPRT) with multilevel simultaneous integrated boost (MLSIB) combined with piroxicam and chemotherapy for the treatment of canine transitional cell carcinoma (TCC) of the lower urinary tract with muscle invasion TCC.
