Small cell carcinoma (SmCC) of the bladder is a rare disease. We retrospectively studied a large series of bladder SmCC from a single institution. The patients included 69 men and 12 women with a mean age of 68years. Most bladder SmCC were presented at advanced stage with tumors invading the muscularis propria and beyond (n=77). SmCC was pure in 27 cases and mixed with other histologic types in 54 cases, including urothelial carcinoma (UC) (n=32), UC in situ (n=26), glandular (n=14), micropapillary (n=4), sarcomatoid (n=4), and squamous (n=3), and plasmacytoid (n=1) features...

Alpha-Klotho (KLα) and beta-Klotho (KLβ) have recently been reported to correlate with cancer prognosis in some malignancies and we previously reported the association between KLα, KLβ, and urothelial carcinoma of the bladder (UCB), indicating that KLβ acts as a tumor promoter. However, the association between gamma-Klotho (KLγ) and cancer prognosis remains unclear. In the present study, we evaluated the association between KLγ and UCB. To evaluate the effect of KLγ on human bladder cancer cell lines in vitro assays were performed...

Urothelial carcinoma in situ (CIS) of the bladder with glandular differentiation (CIS-GL) is rare with some showing an association with small cell carcinoma. There is a paucity of data on whether CIS-GL diagnosed in the absence of invasive carcinoma is associated with an increased risk of developing small cell carcinoma of the bladder. Twenty-seven cases of CIS-GL were identified from the consult files of one of the authors from 2008 to 2015 without prior or coexisting invasive carcinoma at the time of diagnosis...

BACKGROUND The lipid-rich variant is a rare and aggressive type of urothelial carcinoma (UCa), with less than 40 cases reported in the literature. This variant usually presents as an advanced-stage primary tumor. CASE REPORT We report the case of a 61-year-old man with previous history of T1 high-grade conventional urothelial carcinoma treated with local therapy. The patient later presented with a new 6.5-cm exophytic bladder mass. Histopathological examination revealed a T2 urothelial carcinoma of the lipid-rich variant...

Aristolochic acid I (AAI) is a phytocompound that is linked to the progressive renal disease and development of human urothelial carcinoma. The bladder cancer-associated protein (BLCAP) gene exhibits a tumor suppressor function in various tumors, including bladder carcinoma. This study evaluated the effect of AAI on BLCAP expression and its associated mechanism in human cells. Administering AAI to human embryonic kidney cells (HEK293), human proximal tubule epithelial cells (HK-2) and urinary bladder cancer cells (HT-1376) significantly reduced the expression of BLCAP mRNA and protein...

INTRODUCTION: Small cell carcinoma of the bladder (SCCB) is a rare and lethal disease. Previously, we and others have reported a bladder sparing strategy with platinum-etoposide-based chemotherapy followed by radiotherapy of the bladder. Little is known on frequency and treatment of intravesical recurrence following this approach. The objective of this study is to describe the incidence of intravesical recurrences and their management. MATERIALS AND METHODS: Retrospective study including all patients with SCCB treated at a single institution from 1993 until 2016...

Small cell carcinomas (SCCs) are aggressive neoplasms commonly associated with a pulmonary origin. However, albeit rare, extrapulmonary SCC can occur in a variety of sites with an incidence in North America approximated to be 0.1% to 0.4%. Among these sites, approximately 10% of extrapulmonary SCC cases occur in the prostate and are associated with a poor mortality with a median survival of 10 months. Because of the rarity of the prostatic SCC, there is no formal treatment protocol. In this case report, we present a patient who was diagnosed with SCC in the prostate as primary origin...

Neuroendocrine bladder cancer is a relatively rare but often lethal malignancy, with cell of origin, oncogenomic architecture and standard treatment poorly defined. Here we performed comprehensive whole-genome and transcriptome sequencing on a unique cohort of genitourinary neuroendocrine neoplasms, mainly small cell carcinomas of the urinary bladder. The mutational landscape and signatures of neuroendocrine bladder cancer strikingly resembled those in conventional urothelial carcinoma, along with typically mixed histologies, supporting a common cellular origin...

OBJECTIVE: We report 2 cases of small cell neuroendocrine carcinomas (CCP) of the urinary bladder in patients aged 37 and 80 years. CCP is a malignancy with poor prognosis. We review the literature, under the current WHO classification (2016). METHODS: Paraffin blocks were cut for HE staining and immunohistochemistry to analyze the expression of neuroendocrine differentiation. RESULTS: The main diagnosis was based on histopathologic features, which revealed a diffuse growth pattern of small cells with scant cytoplasm and hyperchromatic nuclei...

BACKGROUND: While the standard treatment for stage II-III (non-T4) esophageal squamous cell carcinoma (ESCC) is neoadjuvant therapy followed by esophagectomy, definitive chemoradiation therapy (dCRT) is an option to treat ESCC patients who reject or may not tolerate surgical treatment. Second primary malignancy (SPM) is a problem for long-term survivors after achieving complete response (CR) by dCRT. METHODS: The source of the subjects in this study was the patients with stage II/III (excluding T4 disease) ESCC (UICC6th) who underwent dCRT from 2000 to 2011 at the National Cancer Center Hospital, Japan...

Over the last two decades, molecular-targeted agents have become mainstream treatment for many types of malignancies and have improved the overall survival of patients. However, most patients eventually develop resistance to these targeted therapies. Recently, immunotherapies such as immune checkpoint inhibitors have revolutionized the treatment paradigm for many types of malignancies. Immune checkpoint inhibitors have been approved for treatment of melanoma, non-small cell lung cancer, renal cell carcinoma, head and neck squamous cell carcinoma, Hodgkin's lymphoma, bladder cancer and gastric cancer...

Previous studies have revealed that HURP (also known as DLGAP5 or KIAA0008) is overexpressed in many types of human cancers, such as hepatocellular carcinoma, squamous cell bladder cancer, and transitional cell carcinoma, indicating that HURP is a putative oncoprotein that promotes carcinogenesis through various molecular mechanisms. However, the role of HURP in the pathogenesis of non‑small cell lung cancer (NSCLC) has not been reported. In the present study, we investigated the prognostic value of HURP among NSCLC patients through the GEO database...

High-grade neuroendocrine carcinomas (HGNECs) of the urinary bladder encompass small cell (SCNEC) and large cell neuroendocrine carcinomas (LCNEC). Currently, recommended initial management is with systemic chemotherapy, followed by consolidative therapy with either radical cystectomy or radiotherapy in patients with localized disease. Nevertheless, survival in this setting remains poor. We therefore evaluated the potential to modify arginine metabolism as an alternative, targeted therapy approach in these carcinomas...

Small-cell neuroendocrine cancers often originate in the lung but can also arise in the bladder or prostate. Phenotypically, small-cell carcinoma of the bladder (SCCB) shares many similarities with small-cell lung cancer (SCLC). It is unknown whether SCCB and SCLC share common genetic driver mutations.

REVIEW
Udom Lao-On, Paul V Attwood, Sarawut Jitrapakdee
Pyruvate carboxylase (PC), an anaplerotic enzyme, plays an essential role in various cellular metabolic pathways including gluconeogenesis, de novo fatty acid synthesis, amino acid synthesis, and glucose-induced insulin secretion. Deregulation of PC expression or activity has long been known to be associated with metabolic syndrome in several rodent models. Accumulating data in the past decade clearly showed that deregulation of PC expression is associated with type 2 diabetes in humans, while targeted inhibition of PC expression in a mouse model reduced adiposity and improved insulin sensitivity in diet-induced type 2 diabetes...
