TNM staging towards a personalized approach in metastatic urothelial carcinoma: what will the future be like?-a narrative review.

Transl Androl Urol 2021 Mar;10(3):1541-1552

Oncologia Medica, Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy.

The American Joint Committee of Cancer (AJCC) tumor-node-metastasis (TNM) classification, with its periodical updates and modifications, has represented and still represents the basis of cancer staging. The historical, long-standing limitations of anatomic-based TNM staging have been recently "threatened" by the impressive amount of data derived from molecular analyses, which have led to an unprecedented level of understanding of cancer genomics. In fact, current era of personalized oncology has witnessed important efforts towards the integration between clinical, anatomical and molecular features; however, despite the promises, personalized oncology faces many obstacles, due to the complex relationship between tumor biomarkers, previously unknown cancer subtypes and clinical and anatomical characteristics.

Ghrelin after chemotherapy as a prognostic predictor of progression-free survival in patients with muscle-invasive bladder cancer.

Transl Androl Urol 2021 Mar;10(3):1192-1201

Department of Urology, Gifu University Graduate School of Medicine, Gifu, Japan.

Background: Although the patients with muscle-invasive bladder cancer (MIBC) generally have poor prognosis, the utility of these biomarkers for the prediction of oncological outcomes in MIBC has not been completely explored. Ghrelin regulates processes associated with cancer, including cell proliferation, apoptosis, cell migration, cell invasion, and angiogenesis.

Relationship of frailty with treatment modality selection in patients with muscle-invasive bladder cancer (FRART-BC study).

Transl Androl Urol 2021 Mar;10(3):1143-1151

Department of Urology, Hirosaki University, Graduate School of Medicine, Hirosaki, Japan.

Background: We aimed to investigate the association of frailty with treatment selection in patients with muscle-invasive bladder cancer (MIBC) as frailty is one of the key factors for modality selection.

Methods: We retrospectively evaluated frailty in 169 patients with MIBC from January 2014 to September 2020 using the Fried phenotype, modified frailty index, and frailty discriminant score. The primary purpose was comparing the frailty between the patients who underwent radical cystectomy (RC) with those who had trimodal therapy (TMT) for bladder preservation. Read More

CD122-directed interleukin-2 treatment mechanisms in bladder cancer differ from αPD-L1 and include tissue-selective γδ T cell activation.

J Immunother Cancer 2021 Apr;9(4)

Mays Cancer Center, University of Texas Health San Antonio, San Antonio, Texas, USA

Background: Anti-programmed death-ligand 1 (αPD-L1) immunotherapy is approved to treat bladder cancer (BC) but is effective in <30% of patients. Interleukin (IL)-2/αIL-2 complexes (IL-2c) that preferentially target IL-2 receptor β (CD122) augment CD8 antitumor T cells known to improve αPD-L1 efficacy. We hypothesized that the tumor microenvironment, including local immune cells in primary versus metastatic BC, differentially affects immunotherapy responses and that IL-2c effects could differ from, and thus complement αPD-L1.

Comput Med Imaging Graph 2021 Mar 31;90:101911. Epub 2021 Mar 31.

Bioengineering Department, University of Louisville, Louisville, KY, USA. Electronic address:

Appropriate treatment of bladder cancer (BC) is widely based on accurate and early BC staging. In this paper, a multiparametric computer-aided diagnostic (MP-CAD) system is developed to differentiate between BC staging, especially T1 and T2 stages, using T2-weighted (T2W) magnetic resonance imaging (MRI) and diffusion-weighted (DW) MRI. Our framework starts with the segmentation of the bladder wall (BW) and localization of the whole BC volume (V) and its extent inside the wall (V). Read More

Department of Urology, Kaohsiung Medical University Hospital, Kaohsiung Medical University, Kaohsiung, Taiwan.

Upper tract urothelial carcinoma (UTUC) is a rare tumor with an incidence that varies greatly between Eastern and Western countries. Transaldolase 1 (TALDO1) is a rate-limiting enzyme of the pentose phosphate pathway. In humans, aberrant TALDO1 activity has been implicated in various autoimmune diseases and malignancies; however, the function of TALDO1 in UTUC has not been previously investigated. Read More

Factors associated with utilization of neoadjuvant chemotherapy in charlson comorbidity zero non-metastatic muscle-invasive bladder cancer patients.

Int Braz J Urol 2021 Jul-Aug;47(4):803-818

Department of Population, Health University of Kansas Health System, Kansas City, KS, United States.

Background: Guideline-based best practice treatment for muscle invasive bladder cancer (MIBC) involves neoadjuvant chemotherapy followed by radical cystectomy (NACRC). Prior studies have shown that a minority of patients receive NACRC and older age and renal function are drivers of non-receipt of NACRC. This study investigates treatment rates and factors associated with not receiving NACRC in MIBC patients with lower comorbidity status most likely to be candidates for NACRC. Read More

Human bone marrow-derived stromal cell behavior when injected directly into the bone marrow of NOD-scid-gamma mice pre-conditioned with sub-lethal irradiation.

Stem Cell Res Ther 2021 Apr 12;12(1):231. Epub 2021 Apr 12.

School of Biomedical Sciences, Faculty of Health, Queensland University of Technology (QUT), Brisbane, Australia.

Background: Direct bone marrow injection of cells into murine marrow cavities is used in a range of cell characterization assays and to develop disease models. While human bone marrow-derived stromal cells (hBMSC, also known as mesenchymal stem cells (MSC)) are frequently described in therapeutic applications, or disease modeling, their behavior following direct injection into murine bone marrow is poorly characterized. Herein, we characterized hBMSC engraftment and persistence within the bone marrow of NOD-scid interleukin (IL)-2γ (NSG) mice with or without prior 2 Gy total-body γ-irradiation of recipient mice.

Department of Urology, University of Tuebingen Hospital, Hoppe-Seyler-Str. 3, 72076, Tübingen, Germany.

Background: CD276 is an immune checkpoint molecule. Elevated CD276 expression by urothelial carcinoma is associated with poor prognosis, but little is known about its expression across different tumor stages. We therefore investigated CD276 expression in bladder cancer (BC) cells and in tissue samples of BC stages from pT2 to pT4. Read More

Cholecystectomy, porta hepatis stripping, and omental bursectomy.

Gland Surg 2021 Mar;10(3):1230-1234

Division of Gynecologic Oncology, Ajou University School of Medicine, Suwon, Korea.

As ovarian cancer commonly involves the visceral organs without boundary, more aggressive procedures are adopted during cytoreductive surgery. One of the most difficult aspect of the operation involves the procedure for the gall bladder, porta hepatis, and omental bursa. As the upper abdominal surgical field is not familiar to the gynecologic surgeon, and the vital organs or vessels are densely positioned, these procedures can be challenging for achieving the optimal cytoreductive surgery.

Non-prostate uptake on F-PSMA-1007 PET/CT: a case of myeloma.

BJR Case Rep 2021 Apr 3;7(2):20200102. Epub 2020 Nov 3.

Department of Radiology, Royal United Hospital, Combe Park, Bath, Avon, United Kingdom.

Prostate-specific membrane antigen (PSMA), a glycoprotein that is highly expressed in prostate cancer, has been used as a target for molecular radiotherapy as well as imaging. Over the last couple of years, F-PSMA gained popularity due to its longer half-life (110 min) compared to gallium Ga-PSMA (68 min). This has helped the dissemination beyond large metropolitan centres. Read More
