GayAbstractBackgroundIn patients with rare histologies of bladder cancer, including adenocarcinoma of the bladder (ACB) and squamous-cell carcinoma (SCC), there are limited standard therapy options, defining an unmet medical need.ObjectiveIn this comparative comprehensive genomic profiling (CGP) study, genomic alterations (GAs), and immuno-oncology (IO) biomarkers have been analyzed.Design, setting, and participantsWithin the Foundation Medicine database, 143 cases with centrally reviewed pure ACB, 2142 with pure urothelial carcinoma (UC), and 83 with pure SCC were subjected to CGP. All patients developed advanced disease following a primary diagnosis of bladder cancer.InterventionCGP using a hybrid capture–based assay and immunohistochemistry (IHC).Outcome measurements and statistical analysisTumor mutational burden (TMB) was determined on 1.1 Mbp of sequenced DNA, and microsatellite instability (MSI) was determined on 114 loci. Programmed cell-death ligand-1 (PD-L1) expression was determined by IHC (Ventana SP-142 assay), with>1% tumor cells (TCs) or tumor-infiltr...

Bladder cancer (BC) is a major global health challenge with 549,393 new cases and nearly 200,000 deaths during 2018 [1]. In 2018, estimated BC incidence and mortality in Europe were 197,100 and 65,000 cases, respectively [2]. Urothelial carcinoma (UC) is the most common histologic subtype of BC and represents nearly 90% of all cases. Other less common subtypes are squamous cell carcinoma, adenocarcinoma, and small cell carcinoma [3]. Around 30% of cases are diagnosed as muscle-invasive bladder cancer (MIBC) and most are locally advanced or metastatic at diagnosis, requiring systemic treatment [4].

CONCLUSION: Long non-coding RNA DLEU1 is likely to represent an available biomarker or a potential therapeutic target in multiple tumors. PMID: 31969095 [PubMed - as supplied by publisher]

In conclusion, the majority of bladder cancers following brachytherapy in this cohort were of high grade and low stage at diagnosis, most of them demonstrating luminal immunophenotype. A significant number of variant histologies are seen, each demonstrating a specific immunophenotype.

Abstract CD28H and B7-H5 have been identified as receptor-ligand pairs in B7/CD28 family, and have costimulatory activity in immune cells. Here, we have systematically reviewed the research reports on the CD28H/B7-H5 pathway. It was found that CD28H is mainly expressed in T cells and natural killer (NK) cells with naive and poorly differentiated properties, and repeated antigen stimulation leads to permanent loss of CD28H. In tumors, CD28H is mainly expressed in tissue-resident memory (TRM ) lymphocyte T cells, which is associated with improved tumor prognosis. B7-H5 is a ligand for CD28H and is widely expressed i...

Conclusion: Low expressing levels of miRNA-15a indicated poor OS, while miRNA-15a can be used as a prediction biomarker in different cancer types. PMID: 31061821 [PubMed - indexed for MEDLINE]

CONCLUSION: NUBTs present with similar clinicoradiological findings; however, their histological features along with immunohistochemistry help in the definite diagnosis. One should be aware of these tumors as they frequently present diagnostic and therapeutic challenge. Most of these neoplasms present at an advanced stage. Large or multicentric randomized controlled studies are needed to know the exact behavior and prognosis of these tumors.

This study is an important step forward in highlighting C1q as a new prognostic candidate biomarker for a range of carcinomas. Methods Oncomine Database Analysis The expression levels of C1QA, C1QB, and C1QC genes in various carcinomas were analyzed using Oncomine (www.oncomine.org), a cancer microarray database and web-based data mining platform from genome-wide expression analyses (22, 23). We compared the differences in mRNA level between normal tissue and carcinoma. The mRNA expression levels in neoplastic tissues compared to the healthy tissues were obtained as the parameters of p-value 2, and gene ranking in the t...

Conclusions: In OSCC, very low preoperative NLR values have a negative prognostic impact on survival and recurrence, similarly to high ratios. ENE and perineural spread are the most important clinical-pathologic prognosticators. Introduction Oral squamous cell carcinoma (OSCC) accounts for more than 95% of oral tumors and is the eighth most frequent cancer worldwide, with an estimated incidence of 640,000 new cases per year (1). Survival of OSCC has slightly improved over the last 30 years, probably as a consequence of multimodal treatment spreading. However, intensified therapeutic regimens can result in signific...
