Small cell carcinoma of the ovary, hypercalcemic type (SCCOHT), is a rare SMARCA4-driven aggressive malignancy of young age characteristically associated with paraneoplastic hypercalcemia. Comparable neoplasms/presentations have not been reported in males. A 39-year-old male heart transplant recipient (HTX 40 months previously) presented with multiple liver nodules and hypercalcemic crisis. The serum parathyroid hormone-related protein (PTHrp) was significantly elevated (241 pg/ml; reference value < 57)...

Treatment options for metastatic urothelial carcinoma (mUC) remained relative unchanged over the last 30 years with combination chemotherapy as the mainstay of treatment. Within the last year the landscape for mUC has seismically shifted following the approval of five therapies targeting the programmed cell death protein (PD-1)/programmed cell death ligand 1 (PD-L1) axis. Notably, the anti-PD-1 antibody pembrolizumab demonstrated improved OS relative to chemotherapy in a randomized phase III study for second line treatment of mUC; this level 1 evidence led to approval from the U...

Microcystic urothelial carcinoma is a rare variant of invasive transitional cell carcinoma recognized by the WHO classification. It is characterized by its deceptively benign appearance. The clinical course of this uncommon variety of carcinoma is not well known and their histological and immunohistological features are not well defined. We report a case of a 37-year-old man with a microcystic transitional cell carcinoma of the urinary bladder. He was diagnosed 4 years ago with cystitis glandularis lesions and nephrogenic adenoma...

AIMS: The role of PD-1 (programmed cell death 1) expression on the clinical outcome of upper tract urothelial carcinoma has not yet been elucidated in detail. MATERIALS AND METHODS: PD-1 expression was immunohistochemically examined in 181 upper tract urothelial carcinoma patients who underwent radical nephroureterectomy. A part of PD-1 protein expression in the tumour periphery and tumour nest was evaluated separately. The PD-1-positive cells were counted in the area showing the highest density of PD-1 expression at a magnification of 400×...

Objectives: As the second cause of cancer death, gastric cancer (GC) is one of the eminent dilemmas all over the world, therefore investigating the molecular mechanisms involved in this cancer is pivotal. Unrestricted proliferation is one of the characteristics of cancerous cells, which is due to deficiency in cell regulatory systems. Long non-coding RNAs (lncRNAs) have emerged as critical regulators of the epigenome. lncRNA extra coding CEBPA (ecCEBPA) is involved in DNA methylation...

Metastatic bladder cancer is an aggressive malignancy with a poor prognosis when presenting with advanced stage. Cisplatin-based therapy has been the mainstay of first-line treatment but therapy in second-line setting has been an unmet medical need for decades. Moreover, many patients are unable to receive cisplatin-based therapy. Recently, immune-checkpoint inhibitors transformed the management and prognosis of many malignancies and will certainly redefine the standard of care for bladder cancer. Atezolizumab, an antiprogrammed cell death ligand-1 antibody, was the first immune-checkpoint inhibitor to be approved by the US FDA in May 2016 for patients with urothelial carcinoma...

Urothelial carcinoma remains a clinical challenge: non-muscle-invasive disease has a high rate of recurrence and risk of progression, and outcomes for patients with advanced disease are poor, owing to a lack of effective systemic therapies. The Rho GTPase family of enzymes was first identified >30 years ago and contains >20 members, which are divided into eight subfamilies: Cdc42, Rac, Rho, RhoUV, RhoBTB, RhoDF, RhoH, and Rnd. Rho GTPases are molecular on-off switches, which are increasingly being understood to have a critical role in a number of cellular processes, including cell migration, cell polarity, cell adhesion, cell cycle progression, and regulation of the cytoskeleton...

Immune checkpoint inhibitors are a new class of cancer therapeutics that have demonstrated striking successes in a rapid series of clinical trials. Consequently, these drugs have dramatically increased in clinical use since being first approved for advanced melanoma in 2011. Current indications in addition to melanoma are non-small cell lung cancer, head and neck squamous cell carcinoma, renal cell carcinoma, urothelial carcinoma, and classical Hodgkin lymphoma. A small subset of patients treated with immune checkpoint inhibitors undergoes an atypical treatment response pattern termed pseudoprogression: New or enlarging lesions appear after initiation of therapy, thereby mimicking tumor progression, followed by an eventual decrease in total tumor burden...

CONTEXT: High-grade urothelial carcinoma (UC) cells have many appearances on urine cytology, but according to The Paris System, they can be easily distinguished from umbrella cells. OBJECTIVE: We aimed to define the incidence and appearance of high-grade UC cells that resemble umbrella cells in Cytospin preparations on urine cytology. RESULTS: Cytospin preparations from 331 cases with biopsy follow-up (230 benign/low-grade and 101 malignant [22 carcinoma in situ, 52 papillary, 19 invasive UC, 8 other] cases) were reviewed...

Chemotherapy resistance has become the main obstacle for the effective treatment of human cancers. Long non-coding RNA urothelial cancer associated 1 (UCA1) is generally regarded as an oncogene in some cancers. However, the function and molecular mechanism of UCA1 implicated in cisplatin (CDDP) chemoresistance of oral squamous cell carcinoma (OSCC) is still not fully established. UCA1 expression in tumor tissues and cells was tested by qRT-PCR. MTT, flow cytometry and caspase-3 activity analysis were explored to evaluate the CDDP sensitivity in OSCC cells...

The long non-coding RNA (lncRNA) urothelial carcinoma associated 1 (UCA1) is an oncogenic lncRNA in bladder cancer, and its upregulation is associated with enhanced cell invasion. However, the underlying mechanism remains to be elucidated. The present study demonstrated that UCA1 was positively associated with cell invasion ability and promoted epithelial-mesenchymal transition (EMT) of bladder cancer cells by inducing high mobility group box 1 (HMGB1). Furthermore, bioinformatics and luciferase reporter assays demonstrated binding sites of the tumor suppressive miR-143 within UCA1 and the 3'untranslated region of HMGB1...

Eruption of lymphocyte recovery (ELR) may occur during bone marrow aplasia after chemotherapies. We reviewed the clinical and pathologic features of 12 patients (male/female: 7/5, median age: 61years) with an atypical ELR histologically mimicking a primary cutaneous T-cell lymphoma (CTCL) such as Sézary Syndrome or CD30+ T-cell lymphoproliferative disorder (LPD). All the patients displayed an erythematous maculopapular eruption on the trunk and the limbs, associated with fever. All but one had received a polychemotherapy for an acute myeloid leukemia (n=10) or an urothelial carcinoma (n=1) before the occurrence of the skin eruption...

Melatonin counteracts tumor occurrence and tumor cell progression in several cancer types in vitro and in vivo. It acts predominantly through its melatonin receptor type 1A (MTNR1A), and genetic variations of MTNR1A affect the susceptibility several diseases and cancer. The purpose of this study was to explore the effect of MTNR1A gene polymorphisms on the susceptibility to and clinicopathological characteristics of urothelial cell carcinoma (UCC). We recruited 272 patients with UCC and 272 normal controls to analyze three common single-nucleotide polymorphisms (SNPs) (rs2119882, rs13140012, and rs6553010) of MTNR1A related to cancer risk and clinicopathological relevance according to a TaqMan-based real-time polymerase chain reaction (PCR)...

BACKGROUND: Avelumab has recently been approved by the Food and Drug Administration for the therapy of Merkel cell carcinoma and urothelial carcinoma. M7824 is a novel first-in-class bifunctional fusion protein comprising a monoclonal antibody against programmed death-ligand 1 (PD-L1, avelumab), fused to the extracellular domain of human transforming growth factor beta (TGFβ) receptor 2, which functions as a TGFβ "trap." Advanced urothelial tumors have been shown to express TGFβ, which possesses immunosuppressive properties that promote cancer progression and metastasis...
