Authors: Montazeri K, Bellmunt J Abstract Introduction: Since the approval of immune checkpoint inhibitors (ICIs), there has been continuing and significant progress in urothelial cancer (UC) treatment. However, only about one fifth of UC patients respond to ICI. Recently, erdafitinib was developed for treating locally advanced or metastatic UC (mUC) with FGFR3 or FGFR2 alterations, accounting for 15-20% of patients. Erdafitinib is the first targeted therapy ever approved for mUC.Areas covered: This review summarizes the preclinical and clinical data on erdafitinib for UC. PubMed search and relevant articles presen...

Authors: Cho CJ, Yang CW, Wu CL, Ho JY, Yu CP, Wu ST, Yu DS Abstract Gemcitabine (GCB), which functions via the inhibition of DNA synthesis, is commonly used in the treatment of bladder cancer; however, its response rate is not satisfactory due to the development of drug resistance. The potential for phytochemicals to reverse drug resistance in bladder cancer tumor cells was evaluated. A human bladder cancer cell line, T24, was cultured, and GCB-resistant cells (T24-GCB) were also established. The acquired resistance of T24-GCB to GCB was measured using an MTT assay. The gene expression of ATP-binding cassette (ABC...

LncRNA AWPPH promotes the invasion and migration of glioma cells through the upregulation of HIF1α. Oncol Lett. 2019 Dec;18(6):6781-6786 Authors: Zhang T, Wang F, Liao Y, Yuan L, Zhang B Abstract Long non-coding RNA (lncRNA) AWPPH has been revealed to serve pivotal roles in bladder cancer and liver cancer. The aim of the present study was to determine the involvement of lncRNA AWPPH in glioma. It was observed in the present study that the expression levels of AWPPH in plasma were significantly higher in patients with metastatic glioma compared with those in patients with non-metastatic glioma and...

This study aimed to provide mechanistic insights into mitophagy pathway associated with papillomavirus infection in urothelial cells of cattle. The elimination of mitochondria via autophagy, termed mitophagy, is an evolutionarily conserved mechanism for mitochondrial quality control and homeostasis. PINK1/parkin-mediated mitophagy, a ubiquitin-dependent selective autophagy of dysfunctional mitochondria, has been described here, for the first time, in urothelial cells from 25 bladder cancers in cattle infected by bovine papillomavirus (BPV). The expression of BPV-2 and BPV-13 E5 oncoprotein was detected by RT-PCR. Abnormal ...

Eleven studies met the ...

We present 3 cases with false-negatives for local (recurrent) prostate cancer on 68Ga-PSMA PET/CT, using multiparametric MRI and histopathology as reference standard. Metal artifact of prostate gold markers placed for external beam radiation therapy, low level of PSMA uptake, and bladder spillover are potential causes of misinterpretation. Awareness of these diagnostic pitfalls may improve 68Ga-PSMA PET/CT interpretation.

Urothelial carcinoma (UC) is the most common malignant neoplasm of the bladder that encompasses a wide spectrum of histopathologic features and various molecular alterations and subtypes, responsible for its significant morphologic and genomic heterogeneity. Morphologically, in addition to classic UC (not otherwise specified), many well documented variant histologies are a common finding in invasive UC, and include squamous, glandular, micropapillary, sarcomatoid, small cell/neuroendocrine, clear cell, lymphoepithelioma-like, and plasmacytoid types, among others. This review provides an update on the recent advances in the...

Authors: Shen H, Liao K, Wu W, Yu H, Wu H Abstract A total of six male patients, who had undergone radical cystectomy and sigma-rectum pouch surgery due to bladder cancer (2-5 years previously), developed hyperchloremic metabolic acidosis, hypokalemia and renal dysfunction. The patients underwent urinary undiversion surgery (the pouch was isolated from the intestinal tract, abdominal ostomy was performed, and the sigmoid colon and rectum were reconnected) and blood gas and electrolyte analysis and renal function were compared pre- and post-surgery. Blood hydrocarbonate levels significantly improved 3 months post-su...

Authors: Wang W, Zhang L, Wang X, Lin D, Pan Q, Guo L Abstract Pioglitazone, a type of insulin sensitizer, serves as an effective anti-hyperglycemic drug. The mechanism of action of pioglitazone is through the activation of the peroxisome proliferator-activated receptor (PPAR), which results in enhanced insulin sensitivity of peripheral tissues and the liver, causing a reduction in the production and output of liver sugar. It has been reported that pioglitazone increases the risk of bladder cancer, but the underlying mechanisms have remained elusive. It was hypothesized that modulation of pioglitazone activity may ...

CONCLUSIONS: Our study suggested a vital regulatory mechanism of CASC15 in BLCA, and the CASC15/miR-130b-3p axis might serve as a new therapeutic interventional target for BLCA patients. PMID: 31799648 [PubMed - in process]
