Beyond the genome: MALAT1's role in advancing urologic cancer care. Pathol Res Pract 2024; 256:155226. [PMID: 38452585 DOI: 10.1016/j.prp.2024.155226] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 02/07/2024] [Accepted: 02/21/2024] [Indexed: 03/09/2024]
Abstract
Urologic cancers (UCs), which include bladder, kidney, and prostate tumors, account for almost a quarter of all malignancies. Long non-coding RNAs (lncRNAs) are tissue-specific RNAs that influence cell growth, death, and division. LncRNAs are dysregulated in UCs, and their abnormal expression may allow them to be used in cancer detection, outlook, and therapy. With the identification of several novel lncRNAs and significant exploration of their functions in various illnesses, particularly cancer, the study of lncRNAs has evolved into a new obsession. MALAT1 is a flexible tumor regulator implicated in an array of biological activities and disorders, resulting in an important research issue. MALAT1 appears as a hotspot, having been linked to the dysregulation of cell communication, and is intimately linked to cancer genesis, advancement, and response to treatment. MALAT1 additionally operates as a competitive endogenous RNA, binding to microRNAs and resuming downstream mRNA transcription and operation. This regulatory system influences cell growth, apoptosis, motility, penetration, and cell cycle pausing. MALAT1's evaluation and prognosis significance are highlighted, with a thorough review of its manifestation levels in several UC situations and its association with clinicopathological markers. The investigation highlights MALAT1's adaptability as a possible treatment target, providing fresh ways for therapy in UCs as we integrate existing information The article not only gathers current knowledge on MALAT1's activities but also lays the groundwork for revolutionary advances in the treatment of UCs.

Abstract
Prostate cancer (PCa) is today the second most common cancer in the world, with almost 400,000 deaths annually. Multiple factors are involved in the etiology of PCa, such as older age, genetic mutations, ethnicity, diet, or inflammation. Modern treatment of PCa involves radical surgical treatment or radiation therapy in the stages when the tumor is limited to the prostate. When metastases develop, the standard procedure is androgen deprivation therapy, which aims to reduce the level of circulating testosterone, which is achieved by surgical or medical castration. However, when the level of testosterone decreases to the castration level, the tumor cells adapt to the new conditions through different mechanisms, which enable their unhindered growth and survival, despite the therapy. New knowledge about the biology of the so-called of castration-resistant PCa and the way it adapts to therapy will enable the development of new drugs, whose goal is to prolong the survival of patients with this stage of the disease, which will be discussed in this review.

Abstract
Accumulating evidence indicates that hypoxia is highly associated with bladder cancer genesis, progression, and immune microenvironment. Nevertheless, few studies have identified the role of hypoxia-related genes as a prognostic signature in bladder cancer. This study aimed to establish a hypoxia-related signature with high accuracy for prognosis and immune microenvironment prediction in bladder cancer. We obtained expression profiles and clinical information from Gene Expression Omnibus and The Cancer Genome Atlas. Then the univariate Cox regression, random survival forest algorithm, and multivariate Cox regression analysis were conducted to identify the core genes and four hypoxia-related genes (ANXA2, GALK1, COL5A1, and HS3ST1) were selected to construct the signature. Kaplan-Meier survival analysis demonstrated that patients with a low-risk score had a higher disease-specific survival rate (p < 0.0001). The areas under the curve of the signature were 0.829 at 1 year, 0.869 at 3 years, and 0.848 at 5 years, respectively. Additionally, we found this hypoxia-related signature was highly correlated with tumor immune microenvironment and had the potential to predict the efficacy of immunotherapy. In summary, our study developed a hypoxia-related signature, which had high accuracy for prognosis prediction and the potential to guide the immunotherapy for bladder cancer patients.

Abstract
Over 30 years' successful application of Bacillus Calmette Guerin (BCG) to the clinical treatment of bladder cancer has proved it one of the most promising immunotherapies for cancer. However, the applications and achievements have failed to uncover the mechanism of BCG works on bladder cancer fully. Clinically, the administration of BCG on patients results in no effect, or apparent resistance, and even severe adverse reactions, which are inexplicable. At present, the widely confirmed and accepted immunity mechanism of BCG fall in the processes of the absorption after the instillation of BCG, the internalization of BCG, cytokine release induced by a series of signal transduction pathways, and the effect stage of innate and acquired immune responses. Nonetheless, the limited ascertainments of the mechanism of BCG action cannot fully explain the clinical phenomenon caused by BCG. Therefore, the other mechanisms of BCG action have remained the research hotspot aiming to explore more targeted treatments or to initiate new therapeutic methods avoiding harm. By summarizing the recent research achievements of the mechanism of BCG works on bladder cancer, this review aims to provide clues for researchers to quest more valuable ideas.

Abstract
BACKGROUND Immune checkpoint inhibitors (ICI) have led to great advances in the therapy of metastatic renal cell and urothelial carcinoma. Currently ICI are approved for the first-line therapy of cisplatin-unfit patients (Atezolizumab, Pembrolizumab) and second-line therapy in patients with metastasized urothelial cancer (Atezolizumab, Nivolumab, Pembrolizumab). For the therapy of metastasized RCC, Nivolumab is approved as a second-line therapy and in combination with the CTLA‑4 antibody Ipilimumab as a first-line therapy. OBJECTIVES What does the optimized radiological follow-up and therapy response assessment for ICI, which differ in their pathways from common chemotherapeutics and anti-angiogenetic drugs, look like? What strategies are needed to meet the upcoming challenges concerning interpretation of the acquired images? METHODS A systematic literature search was carried out for urothelial and renal cell carcinoma. RESULTS Immune-related response criteria have been introduced to better characterize the imaging changes occurring under ICI, as monitoring response to immunotherapy still relies on RECIST. CONCLUSIONS To properly identify and predict response after treatment with ICI, additional studies with long-term follow-ups are needed. Because of the growing use of ICI, radiologists and urologist should be familiar with common imaging findings (such as pseudo progress) under immunotherapy to correctly interpret these findings in daily routine.

Abstract
The present study aimed to investigate the biological role of the mitochondrial GTPase mitofusin-2 (MFN2) in bladder cancer. MFN2 mRNA expression in tumor and paired adjacent non-tumor tissues from 8 patients was investigated using reverse transcription-quantitative polymerase chain reaction analysis. Immunohistochemistry was used to investigate MFN2 expression in 117 bladder cancer specimens. The associations of MFN2 expression with clinicopathological parameters were evaluated statistically. In addition, the biological role of MFN2 in the proliferation, migration and invasion of bladder cancer cells was examined. It was identified that MFN2 expression was significantly downregulated in bladder cancer tissues compared with normal tissues. MFN2 expression was associated with tumor stage, tumor grade and lymph node status. Furthermore, patients with low MFN2 expression demonstrated a shorter overall survival time (P=0.025). MFN2 knockdown by small interfering RNA promoted cancer cell proliferation, migration and invasion in vitro, and enhanced tumor progression in vivo. Mechanistically, MFN2 was revealed to be involved in Wnt/β-catenin signaling. In conclusion, MFN2 may serve as a potential therapeutic target in the treatment of bladder cancer, and the progress of bladder cancer may be delayed by regulating MFN2 expression.

Abstract
Among all malignant tumors that threaten human health, virus-related tumors account for a large proportion. The treatment of these tumors is still an urgent problem to be resolved. The immune system is the "guard" of the human body, resisting the invasion of foreign substances such as viruses. Studies have shown that immunotherapy has clinical significance in the treatment of a variety of tumors. In particular, the emergence of immune checkpoint inhibitors (ICIs) in recent years has opened a new door to cancer therapy. Considering the potential role of ICIs in the treatment of virus-related cancers, we focused on their therapeutic effect in virus-associated cancers and explored whether the therapeutic effect in virus-associated cancers was related to virus infection status. Although there is no clear statistical significance indicates that ICIs are more effective in virus-associated cancers than non-virus infections, the efficacy of checkpoint inhibitors in the treatment of virus-related cancers is promising. We believe that this research provides a good direction for the implementation of individualized precision medicine.

Abstract
Objective: Our objective was to conduct a meta-analysis to investigate the clinicopathological features and prognostic value of programmed cell death ligand 1 (PD-L1) expression in patients with urothelial carcinoma (UC). Materials and methods: Twenty-seven studies with 4,032 patients were included in the meta-analysis. Pooled ORs and 95% CIs were used to examine the associations between clinical factors and PD-L1 expression. HRs and 95% CIs were extracted from eligible studies. Heterogeneity was evaluated using the chi-squared-based Q test and I2 statistic. Results: Expression of PD-L1 on tumor cells (TCs) was associated with muscle-invasive disease (OR=3.67, 95% CI: 2.53–5.33), and inversely associated with the history of intravesical bacilli Calmette-Guerin therapy (OR=0.39, 95% CI: 0.18–0.82) in bladder cancer patients. PD-L1 expression on TCs was associated with worse overall survival (HR=2.06, 95% CI: 1.38–3.06) in patients with organ-confined bladder cancer. PD-L1 expression in patients with UC was significantly related to better objective response rate after PD-1/PD-L1 antibody treatment. Conclusions: Expression of PD-L1 on TCs was associated with muscle-invasive disease in patients with bladder cancer. Patients with PD-L1-positive UC had a significantly better response to PD-1/PD-L1 targeted treatment.

Prognostic Factor Analyses From the AXIS Trial. Clin Genitourin Cancer 2019; 17:e689-e703. [PMID: 31072748 DOI: 10.1016/j.clgc.2019.03.017] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2019] [Revised: 03/18/2019] [Accepted: 03/24/2019] [Indexed: 01/06/2023]
Abstract
BACKGROUND Axitinib resulted in significantly longer progression-free survival (PFS) versus sorafenib in patients with metastatic renal-cell carcinoma (mRCC) previously treated with sunitinib in the AXIS trial. We report post hoc analyses evaluating patient subgroups that may benefit more from axitinib in this setting. PATIENTS AND METHODS AXIS was an open-label randomized phase 3 trial (NCT00678392) in mRCC patients with disease that failed to respond to one prior systemic therapy. Univariate and multivariate analyses evaluated potential prognostic factors for improved PFS and overall survival (OS) after sunitinib. PFS and OS of axitinib versus sorafenib were assessed within subgroups identified according to these factors. RESULTS Of 723 patients, 389 received first-line sunitinib; 194 and 195 were randomized to second-line axitinib and sorafenib, respectively. Identified prognostic factors were: nonbulky disease (sum of the longest diameter < 98 mm), favorable/intermediate risk disease (Memorial Sloan Kettering Cancer Center or International Metastatic Renal Cell Carcinoma Database Consortium criteria), and no bone or liver metastases. In patients with all of these prognostic factors (n = 86), significantly longer PFS was observed for axitinib versus sorafenib (hazard ratio = 0.476; 95% confidence interval, 0.263-0.863; 2-sided P = .0126). OS (hazard ratio = 0.902; 95% confidence interval, 0.457-1.780; 2-sided P = .7661) was similar between treatments. Across subgroups, PFS was generally longer in patients treated with axitinib versus sorafenib, and OS was generally similar between the two treatments. CONCLUSION In patients with mRCC, axitinib remains a suitable second-line treatment option across multiple subgroups. A relevant reduction in the risk of a PFS event was observed for axitinib compared to sorafenib in selected subgroups of patients.

Abstract
PURPOSE OF REVIEW Recent advances in anticancer immunotherapy have revolutionized the treatment of metastatic renal cell (RCC) and urothelial carcinoma. In this review, we discuss the mechanisms of action of these new therapeutic approaches, explicate the common adverse events, and highlight different imaging-based response criteria. RECENT FINDINGS The recent introduction of immune-checkpoint inhibitors led to substantial advances in therapy of metastatic RCC and urothelial carcinoma. Because of the distinct effector mechanisms of these new substances, atypical response patterns such as transient enlargements of tumor lesions, appearance of new lesions after therapy, no measurable decrease in tumor size, or delayed responses are observed in medical imaging studies. This indicates that the established imaging-based response assessment according to the Response Evaluation Criteria in Solid Tumors (RECIST) guidelines has shortcomings to comprehensively evaluate treatment effects. SUMMARY While monitoring response to immunotherapy still relies on RECIST criteria, immune-related response criteria have been established to better address the imaging changes occurring under immunotherapy. Further studies with long-term follow-up are needed to properly identify and predict response after treatment beyond progression. Because of the expanding clinical use of immune checkpoint inhibitors, radiologists, urologist, and oncologists should be familiar with common imaging findings under this respective therapy.

Abstract
Checkpoint inhibitors targeting the programmed cell death 1 protein (PD-1) and programmed cell death ligand 1 (PD-L1) are demonstrating promising efficacy and appear to be well tolerated in a number of tumour types. In non-small-cell lung cancer, head-and-neck squamous cell carcinoma, and urothelial carcinoma, outcomes appear particularly favourable in patients with high PD-L1 expression. However, assays for PD-L1 have been developed for individual agents, and they use different antibody clones, immunohistochemistry staining protocols, scoring algorithms, and cut-offs. Given that laboratories are unlikely to use multiple testing platforms, use of one PD-L1 assay in conjunction with a specific therapy will become impractical and could compromise treatment options. Methods to harmonize testing methods are therefore crucial to ensuring appropriate treatment selection. This paper focuses on lung, bladder, and head-and-neck cancer. It reviews and compares available PD-L1 testing methodologies, summarizes the literature about comparability studies to date, discusses future directions in personalized diagnostics, and provides a pathologist's perspective on PD-L1 testing in the Canadian laboratory setting.

Abstract
The tumor microenvironment (TME) plays an important role in cancer growth and progression. Paradoxically, the TME is capable of acting as both a potential barrier and facilitator of tumor proliferation by affecting various processes including local growth resistance, immune system interactions, and the formation of distant metastases. This important interaction between cancer cells and their local environment, composed of immune cells, angiogenic cells, lymphatic endothelial cells and cancer-associated fibroblasts is paramount to determine a cancer cell's ability to grow and ultimately metastasize. It is essential to understand this complex interplay in order to define treatment modalities to target the TME as part of anti-cancer therapy.

Abstract
The prognosis of metastatic or relapsed renal cell carcinoma (RCC) or bladder cancer (BC) remains poor despite the introduction of immune checkpoint blockade agents. We aimed to investigate the safety and the feasibility of a vaccination with WT1 peptide-loaded dendritic cells (DCs) and OK-432 adjuvant combined with molecular targeted therapy or conventional chemotherapy. Five eligible patients with metastatic or relapsed RCC and five eligible patients with BC were enrolled. No severe adverse events related to a vaccination were observed. Seven patients with RCC or non-muscle invasive BC had durable stable disease and three other patients had disease progression after DC vaccination. DC vaccination augmented WT1 specific immunity and the reduction of regulatory T cells which might be related to clinical outcome. These results indicate that DC-based immunotherapy combined with a molecular targeted therapy or a conventional chemotherapy is safe and feasible for patients in advanced stage of RCC or BC.
