Bladder cancer, or urothelial carcinoma, is a common, aggressive, and still difficult to predict disease. For adequate therapy, timely diagnosis is essential since early detection of this tumor can significantly increase patient's survival at any age. Molecular genetic studies in cancer patients, including those with urothelial carcinoma, are becoming increasingly important. A number of major molecular genetic biomarkers of urothelial carcinoma are described in the world literature and used in clinical practice, however, information on the role of microRNA (miRNA) studies in the diagnosis of this disease has become available only in recent years.Aim. To examine information of the world literature on the significance of miRNA identification in resected bladder tissues with non-muscle invasive urothelial tumors.Materials and methods. We studied information from the world medical literature in the PubMed, CrossRef and Scopus databases dated between 2001 and 2022 on the significance of miRNA identification in resected bladder tissues with non-muscle invasive urothelial tumors.Results. The results of the studies demonstrate that predictive levels of some miRNAs, as well as their associated proteins, should be assessed in the original tumor tissue and urinary vesicles in different clinical settings. The use of molecular genetic research, as one of the new diagnostic methods, will allow to personalize treatment for a particular patient and, if necessary, make a choice in favor of a more aggressive treatment method. In turn, this will increase the overall survival and quality of life of patients with aggressive tumors.Conclusion. The next few years may bring many new discoveries that will help to unlock the secrets of miRNA dysregulation in urothelial carcinoma, leading to development and application of new targeted therapies in this patient population.","PeriodicalId":216890,"journal":{"name":"Cancer Urology","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117325874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Russian multicenter observational study included 92 consecutive patients with morphologically verified metastatic renal cell carcinoma treated with cabozantinib (60 mg/d) in 16 Russian centers. Median age of the patients was 56 (19-79) years, a male-to-female ratio - 3:1. At the start of cabozantinib therapy 27.2 % of patients had ECOG PS 2. Most common histological type of kidney cancer was clear-cell RCC (90.2 %). Most patients were diagnosed with synchronous (71.7 %) multiple metastases (60.9 %). Previous nephrectomy was performed in 87.0 % of cases. Prognosis according to International Metastatic Renal Cancer Database Consortium (IMDC) score was assessed as favorable in 5.4 %, intermediate - in 58.7 % and poor - in 35.9 % patients. Cabozantinib as the first-line therapy was administered in 9 (9.8 %), following 1-5 lines of systemic treatment - in 83 (90.2 %) cases. Median follow-up was 11 (2.3-44.5) months.Results. In patients, receiving cabozantinib as the first-line therapy, objective response rate was 66.7 %, tumor control was reached in 100 % of cases. Median time to the objective response was 2.6 (1.9-3.6) months, median objective response duration - 13.2 (6.2-21.5) months. Median progression-free survival (PFS) and overall survival (OS) were not reached, 6- and 12-months PFS was 77.8 % and 77.8 %, 6- and 12-months OS - 88.9 % and 88.9 % respectively. Cabozantinib as the second and subsequent lines of therapy provided objective response rate of 34.9 %, tumor control rate - 97.6 %. Median time to the objective response was 2.5 (1.8-4.1) months, median objective response duration - 12.6 (5.5-27.3) months. Median PFS was not reached (6- and 12-months PFS - 92.5 % and 73.1 % respectively), median OS was 32.6 months (6- and 12-months OS - 97.4 % and 80.8 % respectively). Any adverse events (AE) developed in 88.8 %, AE grade III-IV - in 32.6 % of cases. Most frequent AE grade III-IV included arterial hypertension (18.5 %), diarrhea (6.5 %) and palmar-plantar erythrodysesthesia (6.5 %). Unacceptable toxicity demanded treatment cancellation in 2.2 %, therapy interruption - in 16.3 % and dose reduction - in 30.4 % of patients.Conclusion. Cabozantinib as the first and subsequent lines of therapy for metastatic renal cell carcinoma patients in the real world practice demonstrated high efficacy and better tolerability comparing with population assigned for cabozantinib monotherapy in the randomized phase II-III trials.","PeriodicalId":216890,"journal":{"name":"Cancer Urology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133059212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the Urology Center of the Mariinsky Hospital (Saint Petersburg) between 2018 and 2022 robot-assisted partial nephrectomy was performed in 86 patients (46 (59.5 %) men and 40 (40.5 %) women) with stage Т1а (n = 72) and Tib (n = 14) kidney tumors. Mean patient age was 58.0 ± 8.5 years, tumor size varied between 1.2 and 5.2 cm. Seven (7) patients were operated on due to tumor recurrence after previously performed partial nephrectomy. In all cases, lesion was located outside the site of primary resection. Mean time between the 1st and 2nd surgeries was 24 (12-46) months. Histological examination of primary tumor showed renal cell carcinoma in 4 patients, papillary carcinoma in 2 patients, chromophobe carcinoma in 1 patient. In 5 patients, one recurrent lesion was diagnosed, in 2 patients - two. Ligation of the renal artery was performed in 2 patients, its branch - in 3, ischemia-free resection - in 2 patients. Evaluation of mean operating time, blood loss volume, warm ischemia time, pre- and postoperative kidney function was performed.Results. Mean operating time of repeat partial nephrectomy was 180 (130-210) minutes. Warm ischemia time for renal artery ligation was 16 and 20 minutes, for selective ischemia 14, 18 and 24 minutes. Mean blood loss volume was 220 (80-650) ml. No intraoperative complications were observed, grade I-II postoperative complications per the Clavien classification were observed in 2 patients. Mean decrease in glomerular filtration time was 8 % (from 62 to 54 mL/min/1.73 m2). During 16-month follow up period, tumor recurrence was not observed.Conclusion.

Materials and methods. We have studied tumor and perifocal zone fragments of 31 patients with verified non-muscle invasive bladder cancer of low malignant potential and with different probabilities of recurrence. Fifteen (15) patients developed recurrences 6–9 months after combination treatment. The fragments of primary and recurrent tumors were echanically disaggregated and centrifuged at 1500 rpm for 10 minutes. Levels of cytokines interleukin (IL) -1β, -6, -8, -10, -18, tumor necrosis factor α (TNF-α), interferon-γ (Vektor-Best, Russia), and epithelial neutrophil activating peptide 78 (ENA-78) (CXCL-5 chemokine) (Cloud-Clone Corp., USA) were measured in the samples by ELISA. Results were statistically processed using Statistica 13 software (StatSoft Inc., USA), and presented as median and interquartile range – 25th and 75th percentile (Ме [LQ; UQ]).Results. Comparison of cytokine concentrations within the groups showed that the levels of inflammatory cytokines (TNF-α, IL-1β, IL-8, IL-6, IL-18) in tumor tissues were higher than in the perifocal zone tissues. This pattern was expected because tumor is the main site of inflammation. Comparison of these indicators between groups showed that in tumor tissues with an unfavorable course of the disease, namely disease recurrence, the levels of almost all inflammatory cytokines (TNF-α, IL-1β, IL-8, IL-6) were higher.

In 10 % of all cases, nephroblastoma is represented by a hereditary tumor syndrome due to germline mutations in suppressor genes, mainly in the WT1 gene, less often in WT2, WTX, CTNNB1, TP53. These genes are associated with retroelements that play a role in the development of Wilms’ tumor, promoting carcinogenesis, causing genome instability. LINE-1 retroelement is a negative regulator of WT1 expression, while suppressor genes are characterized by suppression of retroelement activity. Part of the pathogenesis of Perlman, Beckwith-Wiedemann, WAGR, and trisomy 18 syndromes caused by germline microdeletions is the activation of retroelements that promote somatic chromosomal rearrangements, including deletions, insertions, and translocations, which are characteristic of sporadic Wilms’ tumor. Long noncoding RNAs and microRNAs are formed from retroelements during evolution or directly during the processing of their transcripts. At the same time, long noncoding RNAs affect the development of Wilms’ tumor by various mechanisms: due to the effect on ferroptosis (lncRNA AC007406.1, AC005208.1, LINC01770, DLGAP1-AS2, AP002761.4, STPG3-AS1, AC129507.1, AC234772.2, LINC02447, AC009570.1, ZBTB20-AS1 and LINC01179), Wnt/β-catenin signaling pathways (HOTAIR, MEG3), apoptosis (HAGLROS), regulation of expression of specific miRNAs (SNHG6, MEG8, XIST, SNHG16, DLEU1, CRNDE, SNHG6, DLGAP1, OSTM1-AS1, EMX2OS, H19). Analysis of the MDTE DB database revealed nephroblastoma-associated miRNAs that originate from retrotransposons. These include miR-192, -335, -378c, -562, -630, -1248. These molecules are promising for possible use in the pathogenetic treatment of Wilms’ tumor due to their effect on pathologically activated retrotransposons.","PeriodicalId":216890,"journal":{"name":"Cancer Urology","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117210141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
