Gemcitabine Plus Cisplatin Split Gemcitabine Plus Carboplatin for Advanced Urothelial Cancer With Cisplatin-unfit Renal Function.

In Vivo 2019 Jan-Feb;33(1):167-172

Department of Integrative Cancer Therapy and Urology, Kanazawa University Graduate School of Medical Science, Kanazawa, Japan.

Background: Combination chemotherapy with gemcitabine and cisplatin is the standard first-line treatment for advanced urinary tract urothelial cancer. Carboplatin is often substituted for cisplatin in patients who are cisplatin-ineligible, such as those with a glomerular filtration rate less than 60 ml/min. However, carboplatin-based chemotherapy has not been not confirmed as meeting the standard of care based on randomized controlled trials, and it is still unclear whether carboplatin can offer prognosis comparable to that with cisplatin.

Predictive ability of renal cortex enhancement in dynamic computed tomography for residual renal function after nephroureterectomy: Comparison with Tc-diethylenetriaminopentacetic acid renography and validation study.

Int J Urol 2019 02 27;26(2):266-272. Epub 2018 Oct 27.

Department of Urology, Tokyo Medical and Dental University Graduate School, Tokyo, Japan.

Objective: To estimate postoperative residual renal function after radical nephroureterectomy for upper tract urothelial carcinoma using the preoperative dynamic computed tomography renal cortex enhancement ratio in comparison with the split kidney glomerular filtration rate measured by Tc-diethylenetriaminopentacetic acid renography.

Methods: A total of 47 patients who received radical nephroureterectomy and underwent both preoperative dynamic computed tomography and renography were the model-development cohort; and 109 patients who underwent dynamic computed tomography alone were the validation cohort. Postoperative renal function of the unremoved kidney was estimated using the following formulas: preoperative estimated glomerular filtration rate × the percentage of total renal cortex radiodensity for the intact kidney in Hounsfield units obtained from corticomedullary phase images in the computed tomography-based model, or the percentage of the total glomerular filtration rate measured by renography in the nuclear model.

[Comparative morphological characteristics and immunophenotype of urothelial carcinomas of the renal pelvis and bladder].

Arkh Patol 2018;80(5):23-32

Department of Pathoanatomy, Tashkent Medical Academy, Tashkent, Respublica Uzbekistan.

Urothelial carcinoma is one of the most frequently diagnosed malignant tumors of the bladder and upper urinary tract, which ranks seventh in the pattern of cancer. Urothelial carcinoma of the renal pelvis is less common; but has a more aggressive clinical course and a worse prognosis than that of the bladder. This is due to the clinical and morphological features of this form of cancer, which, unlike bladder cancer, have not been studied enough. Read More

The two-faced nature of BK polyomavirus: lytic infection or non-lytic large-T-positive carcinoma.

J Pathol 2018 09 31;246(1):7-11. Epub 2018 Jul 31.

Department of Genetics, The University of North Carolina, Chapel Hill, NC, USA.

In immunocompromised patients, reactivation of latent BK polyomavirus (BKPyV) can cause disease with lytic infections of the kidneys and the lower urinary tract. Emerging evidence also links BKPyV to oncogenesis and high-grade intrarenal and transitional cell carcinomas. These neoplasms strongly express polyomavirus large-T antigen as a defining feature; that is, they are 'large-T-positive carcinomas'. Read More

[Treatment with PD-1/PD-L1 and CTLA-4 immune checkpoint inhibitors : Immune-mediated side effects].

Urologe A 2018 May;57(5):543-551

Urologische Klinik und Poliklinik Jena, Universitätsklinikum Jena, Am Klinikum 1, 07747, Jena, Deutschland.

Immune checkpoint inhibitors are a new standard therapy for advanced or metastatic urothelial as well as renal cell carcinoma. Atezolizumab and Pembrolizumab have been approved for the treatment of cisplatin-ineligible patients with transitional call cancer in the 1st line setting; both antibodies and Nivolumab may also be used after platinum based prior therapy. Regarding renal cell carcinoma approval for 1st line treatment with the combination of Nivolumab and Ipilimumab for patients at intermediate or high risk (IMDC) is currently expected. Read More

Perioperative Immunotherapy in Muscle-Invasive Bladder Cancer and Upper Tract Urothelial Carcinoma.

Urol Clin North Am 2018 May;45(2):287-295

Department of Medicine, Genitourinary Oncology Service, Memorial Sloan Kettering Cancer Center, 1275 York Avenue, New York, NY 10065, USA. Electronic address:

Neoadjuvant chemotherapy improves survival in patients with muscle-invasive bladder cancer. However, a significant proportion of patients are ineligible for cisplatin owing to renal impairment or other medical comorbidities. The introduction of anti-programmed cell death protein 1/programmed death-ligand 1(PD1/PD-L1) checkpoint inhibitors has redefined the therapeutic landscape for platinum-resistant urothelial cancers; their clinical efficacy and favorable toxicity render these agents attractive therapeutic options either as monotherapy or in combination with other agents in earlier disease states, including muscle-invasive disease.

Prognostic Factors and Risk Stratification in Invasive Upper Tract Urothelial Carcinoma.

Clin Genitourin Cancer 2018 08 6;16(4):e751-e760. Epub 2018 Feb 6.

Department of Hematology and Medical Oncology, Taussig Cancer Institute, Cleveland Clinic, Cleveland, OH. Electronic address:

Background: Upper tract urothelial carcinoma (UTUC) accounts for approximately 5% of all urothelial cancers. Because of similarities in morphology and histology between UTUC and urothelial carcinoma of the bladder, most treatment guidelines used for UTUC are extrapolated from the urothelial bladder carcinoma setting. With the emergence of new treatment modalities, such as immunotherapy, UTUC-specific prognostic and predictive models are needed. Read More
