The clinicopathological value and exploration of the potential molecular mechanism of microRNA-183-5p (miR-183-5p) have been investigated in various cancers; however, to the best of the author's knowledge, no similar research has been reported for bladder cancer. In the present study, it was revealed that the expression level of miR-183-5p was notably increased in bladder cancer tissues compared with adjacent non-cancerous tissues (P=0.001) and was markedly increased in the tissue samples of papillary, pathological T stage (T0-T2) and pathological stage (I-II) compared with tissue samples of their counterparts (P=0.05), according to data from The Cancer Genome Atlas. Receiver operating characteristic analysis revealed the robust diagnostic value of miR-183-5p for distinguishing bladder cancer from non-cancerous bladder tissues (area under curve=0.948; 95% confidence interval: 0.919-0.977). Amplification and deep deletion of miR-183-5p were indicated by cBioPortal, accounting for 1% (4/412) of bladder cancer cases. Data from YM500v3 demonstrated that compared with other cancers, bladder cancer exhibited high expression levels of miR-183-5p, and miR-183-5p expression in primary solid tumors was much higher compared with solid normal tissues. A meta-analysis indicated that miR-183-5p was more highly expressed in bladder cancer samples compared with normal counterparts. A total of 88 potential target genes of miR-183-5p were identified, 13 of which were discerned as hub genes by protein-protein interaction. The epithelial-to-mesenchymal transition pathway was the most significantly enriched pathway by FunRich (P=0.0001). In summary, miR-183-5p may participate in the tumorigenesis and development of bladder cancer via certain signaling pathways, particularly the epithelial-to-mesenchymal transition pathway. However, the exact molecular mechanism of miR-183-5p in bladder cancer must be validated by and experiments.

Purpose Of Review: This narrative review aims to report upon the existing treatment evidence and strategies for managing lower urinary tract symptoms (LUTS) during treatment, including transurethral resection and intravesical therapy. This review also attempts to examine novel approaches to mitigate treatment-related lower urinary tract symptoms and improve treatment adherence.

Recent Findings: There is sparse but promising evidence in improving LUTS secondary to intravesical therapy.

Evaluating the practical utility of endangered plant species is crucial for their conservation. Nevertheless, numerous endangered plants, including Sinocalycanthus chinensis, lack historical usage data, leading to a paucity of guidance in traditional pharmacological research. This gap impedes their development and potential utilization.

Cardiac metastases from bladder cancer are extremely rare and typically associated with a poor prognosis. We here report a case of a 74-year-old woman who had been diagnosed with multiple bladder cancer and later developed pelvic recurrence and multiple bone metastases. Second-line pembrolizumab treatment achieved complete remission.

Background: Muscle-invasive bladder cancer (MIBC) is a prevalent cancer characterized by molecular and clinical heterogeneity. Assessing the spatial heterogeneity of the MIBC microenvironment is crucial to understand its clinical significance.

Methods: In this study, we used imaging mass cytometry (IMC) to assess the spatial heterogeneity of MIBC microenvironment across 185 regions of interest in 40 tissue samples.

Department of General Surgery (Colorectal Surgery), The Sixth Affiliated Hospital, Sun Yat-sen University, 510655, Guangzhou, Guangdong, China.

Background: Limited research exists on colorectal cancer (CRC) patients with bladder invasion, with survival outcomes post-cystectomy underexplored and a debate between partial and total cystectomy ongoing.

Objective: The study aimed to evaluate the effect of pathological bladder invasion on the long-term tumour prognosis of patients with clinically diagnosed bladder invasion in CRC after cystectomy.

Design: Retrospective, cohort study.
