RESUMEN

Cancer represents a heterogeneous disease with multiple levels of regulation and a dynamic environment that sustains the evolution of the malignant mass. This dynamic is in part sustained by a class of extracellular vesicles termed exosomes that are able to imprint the pathological state by incorporating differential cargos in order to facilitate cell-to-cell communication. Exosomes are stable within the extracellular medium and function as shuttles secreted by healthy or pathological cells, being further taken by the accepting cell with direct effects on its phenotype. The exosomal trafficking is deeply involved in multiple levels of cancer development with roles in all cancer hallmarks. Nowadays, studies are constantly exploring the ability of exosomes to sustain the malignant progression in order to attack this pathological trafficking and impair the ability of the tumor mass to expand within the organisms. As important, the circulatory characteristics of exosomes represent a steady advantage regarding the possibility of using them as minimally invasive diagnosis tools, where cancer patients' present modified exosomal profiles compared to the healthy ones. This last characteristic, as novel diagnosis tools, has the advantage of a possible rapid transition within the clinic, compared to the studies that evaluate the therapeutic meaning.

RESUMEN

INTRODUCTION: Considering the complex set of manual and psychological tasks a surgeon has to perform during the day, it is very important to assess the surgeon's fatigability, reaction time, attention, and memory. OBJECTIVE: Here, we wanted to determine the mental fatigue status of surgeons and how their abilities are affected through a regular workday. METHODS: We included 3 senior urologists and 6 urology residents. In a set period of time, we assessed their fatigue through self-assessed fatigue, Samn-Perelli score, and Karolinska sleepiness scale score. Further, reaction time, attention, and memory correlated with the number of the operations in the day, and total number of operations in that day were assessed. RESULTS: As the number of tasks increases, and as the surgeons advance to the end of the workday, they become more fatigued, reaction time ultimately increases, and attention and memory become slightly altered. CONCLUSIONS: Complications resulting from the fatigue of surgeons could be serious. Their performance status and skills decrease as they perform more tasks or advance through the day.

RESUMEN

Prostate cancer is one of the most encountered cancer diseases in men worldwide and in consequence it requires the improvement of therapeutic strategies. For the clinical diagnosis, the standard approach is represented by solid biopsy. From a surgical point of view, this technique represents an invasive procedure that may imply several postoperative complications. To overcome these impediments, many trends are focusing on developing liquid biopsy assays and on implementing them in clinical practice. Liquid samples (blood, urine) are rich in analytes, especially in transcriptomic information provided by genetic markers. Additionally, molecular characterization regarding microRNAs content reveals outstanding prospects in understanding cancer progression mechanisms. Moreover, these analytes have great potential for prostate cancer early detection, more accurate prostate cancer staging and also for decision making respecting therapy schemes. However, there are still questionable topics and more research is needed to standardize liquid biopsy-based techniques.

RESUMEN

Background and Objectives: Over decades, prostate cancer (PCa) has become one of the leading causes of cancer mortality in men. Extensive evidence exists that microRNAs (miRNAs or miRs) are key players in PCa and a new class of non-invasive cancer biomarkers. Materials and Methods: We performed miRNA profiling in plasma and tissues of PCa patients and attempted the validation of candidate individual miRs as biomarkers. Results: The comparison of tissue and plasma profiling results revealed five commonly dysregulated miRs, namely, miR-130a-3p, miR-145-5p, miR-148a-3p, miR-150-5p, and miR-365a-3p, of which only three show concordant changes-miR-130a-3p and miR-150-5p were downregulated and miR-148a-3p was upregulated in both tissue and plasma samples, respectively. MiR-150-5p was validated as significantly downregulated in both plasma and tissue cancer samples, with a fold change of -2.697 (p < 0.001), and -1.693 (p = 0.035), respectively. ROC analysis showed an area under the curve (AUC) of 0.817 (95% CI: 0.680-0.995) for plasma samples and 0.809 (95% CI: 0.616-1.001) for tissue samples. Conclusions: We provide data indicating that miR-150-5p plasma variations in PCa patients are associated with concordant changes in prostate cancer tissues; however, given the heterogeneous nature of previous findings of miR-150-5p expression in PCa cells, additional future studies of a larger sample size are warranted in order to confirm the biomarker potential and role of miRNA-150-5p in PCa biology.

RESUMEN

PURPOSE: The purpose of this prospective observational study was to evaluate the diagnostic performance of multiparametric (mp) magnetic resonance imaging (MRI) for prostate cancer detection and to assess the interobserver variability, using the Prostate Imaging Reporting and Data Systems (PI-RADS). METHODS: 50 patients (mean age 68.42±6.58 years) with suspected prostate cancer fulfilling the inclusion criteria and without any exclusion criteria were enrolled. All patients were examined with mp-MRI protocol, as per European Society of Urogenital Radiology (ESUR) guidelines, before systematic transrectal ultrasound (TRUS)-guided biopsy. All examinations were read by three independent radiologists with 3-year experience in prostate MRI. Sensitivity (Se), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) were calculated. Interobserver agreement was evaluated using Kappa Cohen coefficient of agreement. RESULTS: mp-MRI and histopathological results of TRUSguided biopsy showed a very good agreement in prostate cancer detection. The overall Se, Sp, PPV and NPV ranged between 93.3-96.7%, 55.0-80.0%, 76.3-87.9% and 88.2-94.1%, respectively. The Kappa Cohen coefficient of interobserver agreement was 0.643 between Readers 1 and 2, 0.664 between Readers 1 and Reader 3 and 0.568 between Readers 2 and 3. CONCLUSIONS: Our results showed a high Se for the detection of prostate cancer with mp-MRI and a high NPV to rule out prostate malignancy. PI-RADS version 2 provides an adequate standardization of mp-MRI, allowing a good level of interobserver agreement.

RESUMEN

The mortality and morbidity that characterize bladder cancer compel this malignancy into the category of hot topics in terms of biomolecular research. Therefore, a better knowledge of the specific molecular mechanisms that underlie the development and progression of bladder cancer is demanded. Tumor heterogeneity among patients with similar diagnosis, as well as intratumor heterogeneity, generates difficulties in terms of targeted therapy. Furthermore, late diagnosis represents an ongoing issue, significantly reducing the response to therapy and, inevitably, the overall survival. The role of non-coding RNAs in bladder cancer emerged in the last decade, revealing that microRNAs (miRNAs) may act as tumor suppressor genes, respectively oncogenes, but also as biomarkers for early diagnosis. Regarding other types of non-coding RNAs, especially long non-coding RNAs (lncRNAs) which are extensively reviewed in this article, their exact roles in tumorigenesis are-for the time being-not as evident as in the case of miRNAs, but, still, clearly suggested. Therefore, this review covers the non-coding RNA expression profile of bladder cancer patients and their validated target genes in bladder cancer cell lines, with repercussions on processes such as proliferation, invasiveness, apoptosis, cell cycle arrest, and other molecular pathways which are specific for the malignant transformation of cells.

RESUMEN

MicroRNAs (miRNAs) are a class of small non-coding RNAs that may function as tumor suppressors or oncogenes. Alteration of their expression levels has been linked to a range of human malignancies, including cancer. The objective of this investigation is to assess the relative expression levels of certain miRNAs to distinguish between prostate cancer (PCa) from benign prostatic hyperplasia (BPH). Blood plasma was collected from 66 patients diagnosed with BPH and 58 patients with PCa. Real-time PCR technology was used to evaluate the relative expression among the two groups for miR-106a-5p and miR-148a-3p. The significant downregulation of both miRNAs in plasma from PCa versus BPH patients suggests their potential utility as diagnostic biomarkers for distinguishing between these conditions. The concurrent utilization of these two miRNAs slightly enhanced the sensitivity for discrimination among the two analyzed groups, as shown in ROC curve analysis. Further validation of these miRNAs in larger patient cohorts and across different stages of PCa may strengthen their candidacy as clinically relevant biomarkers for diagnosis and prognosis.

RESUMEN

PURPOSE: This study aimed to evaluate the indirect effect of the Coronavirus Disease 2019 (COVID-19) pandemic on the surgical outcomes and oncological results of patients who underwent surgery during the lockdown period. METHODS: We analysed data from 423 patients who underwent radical prostatectomy between 2016 and 2022, with a cut-off date of March 16, 2020. Patients were categorised into two groups, namely, pre-lockdown (n = 289) and during lockdown (n = 134). Perioperative variables, histopathological findings and oncological outcomes, including prostate-specific antigen (PSA) levels and biochemical recurrence (BCR), were assessed. RESULTS: The number of radical prostatectomy increased by 24.26% during lockdown. The study included patients with a mean follow-up of 21 months. A nonsignificant trend towards a higher PSA level at presentation was found (14.22 vs. 12.53 ng/dL, p = 0.216). The International Society of Urological Pathology grade was not significantly different among radical prostatectomy specimens (p = 0.669). Lymph node involvement increased during the COVID-19 period (p = 0.046). The pT classification in prostatectomy specimens increased during the pandemic, but the difference from the pre-pandemic value was not statistically significant. The BCR rates were 24.6% pre-lockdown and 29.9% during lockdown (p = 0.136). CONCLUSIONS: The COVID-19 pandemic led to poor postoperative results. Through a 2-year follow-up, this research investigated the effect of the pandemic on the oncological outcomes, particularly BCR, of patients who underwent radical prostatectomy. Further extended investigations and multi-institutional studies should be conducted to quantify the effect of the pandemic on various cancer outcomes and inform crisis management strategies.

RESUMEN

PURPOSE: To analyze the perioperative factors that influence the risk of biochemical recurrence (BCR) in patients with localized PCa undergoing radical prostatectomy Materials and Methods: A total of 457 patients, operated by 2 surgeons in our high-volume oncological center were included in the initial database. Patients who underwent RP for clinically localized PCa in our clinic from 2016 to 2021 were included in the study. Perioperative data were retrospectively reviewed for this study. Follow-up data including post-operative PSA and adjuvant treatment was prospectively gathered by contacting the patients or from the follow-up consultation. Final database was composed of 366 patients who underwent open or 3D laparoscopic RP. Statistical analysis was performed to emphasize the most powerful parameters that influence the BCR.  Results: Accounting for multivariable analysis, 4 parameters were statistically significant: initial PSA (iPSA), Gleason score, vascular involvement and positive surgical margins. For the group of patients with no positive margins, 3 parameters were statistically significant: iPSA above 10,98 ng/mL (AUC=0,71); lymph node involvement and Gleason score. Multivariable Cox regression showed that positive margins and iPSA had a significant impact on the time to BCR. Patients that received adjuvant therapy were excluded from the study. Out of the whole cohort, 27,3% of patients presented BCR. CONCLUSION: Perioperative factors need to be carefully analyzed and a detailed follow-up needs to be conducted in order to assess the risk of biochemical recurrence, resulting in the optimal time for adjuvant treatment implementation.

RESUMEN

Background and objective: While programmes such as the European Basic Laparoscopic Urological Skills have made strides in foundational training, a significant gap exists for intermediate and advanced laparoscopy education. Our objective is to develop and validate the European laparoscopic intermediate urological skills (LUSs2) curriculum, which will establish uniformity in the training of urological laparoscopic procedures and facilitate proficiency among practitioners. Methods: The study combines a literature review, cognitive task analysis development by a steering group, and a two-round Delphi survey involving international experts in urological laparoscopy. Consensus was defined as agreement of ≥70% among experts. The survey included statements on various laparoscopic procedures, assessed on a Likert scale from 1 (strongly disagree) to 9 (strongly agree). Key findings and limitations: The Delphi process achieved consensus on 85% (235/275) of statements, indicating a strong agreement on the curriculum's content. Areas covered include renal hilum dissection, major vessel injury management, enucleation and renorrhaphy, vesicourethral anastomosis, and pyeloplasty. Limitations include the nonsystematic nature of the literature review and potential biases inherent in expert-based consensus methods. Conclusions and clinical implications: The LUSs2 curriculum significantly advances the standardised training of laparoscopic urological skills. It offers a detailed, consensus-validated framework that addresses the need for uniformity in surgical education and aims to enhance surgical proficiency and patient care. Patient summary: This study presents the development of a new standardised training curriculum for urological laparoscopic surgery. We intend this curriculum to improve the quality of surgical training and ensure high-quality patient care.

RESUMEN

Background and aims: Prostate adenocarcinoma (PRAD) is a complex disease that can be driven by alterations in both coding and noncoding genes. Recent research has identified coding and non-coding genes that are considered to play important roles in prostate cancer evolution and which may be used as biomarkers for disease diagnosis, prognosis, and treatment. TP53 is a critical hub gene in prostate cancer. Advanced studies have demonstrated the crosstalk between coding and non-coding RNAs, particularly microRNAs (miRNAs). Methods: In this study, we investigated the roundabout of TP53 and their regulatory miRNAs (miR-15a-5p, miR-34a-5p, and miR-141-3p) based on the TCGA data set. We validated an additional patient cohort of 28 matched samples of patients with PRAD at tissue and plasma level. Results: Therefore, using the UALCAN online database, we evaluated the expression level in PRAD of these genes revealing overexpression of TP53. qRT-PCR validation step endorsed the expression level for these genes. Additionally, we evaluated the expression level of the four key miRNAs (miR-15a-5p, miR-34a-5p, and miR-141-3p) interconnected as a network at tissue and plasma levels. Conclusions: Through these results, we demonstrated the essential function of TP53 and its associated miRNAs that play a significant role in tumor control, highlighting miRNAs' potential as future therapeutic targets and biomarkers with important implications in managing prostate cancer.

RESUMEN

We report the case of a 63-year-old male patient presenting left renal cell carcinoma (75/70/60 mm) associated with retroperitoneal lymph node masses (peri hilar of 15 mm; lombo-aortic of 50/40/30 mm), known also with chronic obstructive pulmonary disease GOLD4, sleep apnea and asthma with oxygen-dependent chronic obstructive respiratory insufficiency, a BMI of 37 with grade III obesity. Surgical treatment was performed using a 3D transperitoneal laparoscopic approach. The surgery lasted 131 minutes, with 400 ml blood loss and grade 1 Clavien-Dindo post operative complications. An optimal pulmonary ventilation of the patient during surgery required a low intra-abdominal pressure (10 mmHg) which raised technical difficulties due to the lymph node mass dissection from the great vessels in a small operative field on an already obese patient with a voluminous renal tumor. The 3D transperitoneal laparoscopic approach was feasible within safe oncologic parameters.

RESUMEN

INTRODUCTION AND IMPORTANCE: Upper tract urothelial carcinoma (UTUC) is a highly systemic aggressive disease with a tendency of rapid lymph node invasion and metastasis presenting poor oncologic outcomes. Ureteral localization of tumors leads to hydronephrosis and early invasion of the muscle wall, being categorized as high risk tumors. CASE PRESENTATION: A 70 years old female was diagnosed with lower left ureteral urothelial tumor associated with hydronephrosis and paraaortic and iliac enlarged lymph nodes. The disease was stratified as high risk upper tract urothelial carcinoma. Treatment consisted in en bloc radical nephroureterectomy, bladder cuff excision and wide lymph node dissection using a combined robotic and 3D laparoscopic approach. CLINICAL DISCUSSION: Surgical challenges are surpassed by the use of minimal invasive approaches that offer precise dissection and tissue manipulation with a fast postoperative recovery and early adjuvant oncologic treatment. Comprehensive and complete lymph node dissection along with precise bladder cuff excision offers improved staging, possibly impacting disease prognosis. CONCLUSION: En bloc minimal invasive radical nephroureterectomy, bladder cuff excision and wide lymph node dissection offer improved surgery time and lymph node dissection, better management of distal ureteral and bladder cuff excision, watertight cystorrhaphy and optimal disease staging. The experience of the main surgeon with 3D laparoscopy was used in the hereby case to optimize operatory time for the renal step of the surgery. The gentle and precise movements of the Da Vinci robot allowed an accurate en bloc dissection (pN2, N4+/15) with implications in staging and possibly also in oncologic outcomes.

RESUMEN

Prostate cancer biology is complex, and needs to be deciphered. The latest evidence reveals the significant role of non-coding RNAs, particularly microRNAs (miRNAs), as key regulatory factors in cancer. Therefore, the identification of altered miRNA patterns involved in prostate cancer will allow them to be used for development of novel diagnostic and prognostic biomarkers. PATIENTS AND METHODS: We performed a miRNAs transcriptomic analysis, using microarray (10 matched pairs tumor tissue versus normal adjacent tissue, selected based on inclusion criteria), followed by overlapping with TCGA data. A total of 292 miRNAs were differentially expressed, with 125 upregulated and 167 downregulated in TCGA patients' cohort with PRAD (prostate adenocarcinoma), respectively for the microarray experiments; 16 upregulated and 44 downregulated miRNAs were found in our cohort. To confirm our results obtained for tumor tissue, we performed validation with qRT-PCR at the tissue and plasma level of two selected transcripts, and finally, we focused on the identification of altered miRNAs involved in key biological processes. RESULTS: A common signature identified a panel of 12 upregulated and 1 downregulated miRNA, targeting and interconnected in a network with the TP53, AGO2, BIRC5 gene and EGFR as a core element. Among this signature, the overexpressed transcripts (miR-20b-5p, miR-96-5p, miR-183-5p) and the downregulated miR-542-5p were validated by qRT-PCR in an additional patients' cohort of 34 matched tumor and normal adjacent paired samples. Further, we performed the validation of the expression level for miR-20b-5p, miR-96-5p, miR-183-5p plasma, on the same patients' cohort versus a healthy control group, confirming the overexpression of these transcripts in the PRAD group, demonstrating the liquid biopsy as a potential investigational tool in prostate cancer. CONCLUSION: In this pilot study, we provide evidence on miRNA dysregulation and its association with key functional components of the PRAD landscape, where an important role is acted by miR-20b-5p, miR-542-5p, or the oncogenic cluster miR-183-96-182.

RESUMEN

INTRODUCTION: The study aimed to evaluate the long-term efficacy of treatment with extract of Serenoa repens (Prostamol Uno) in patients with lower urinary tract symptoms (LUTS) induced by benign prostatic hyperplasia (BPH). PATIENTS AND METHODS: We studied 120 patients with mild or moderate LUTS induced by BPH, maximal urinary flow (Q(max)) <15 ml with a voided volume ≥150 ml, prostate-specific antigen <4 ng/ml, and residual urinary volume <150 ml, treated daily for 24 months with one capsule of 320 mg ethanolic extract of Serenoa repens. RESULTS: Statistically significant improvements in the International Prostate Symptom Score (5.5 points), quality of life (QoL; 1.8 points), Q(max) (5.6 ml/s), International Index of Erectile Function (IIEF; 6.4 points) and reduction in residual urinary volume were observed during the study period. The mean prostate volume at 24 months was 36 ml, compared to 39.8 ml at baseline. CONCLUSIONS: Long-term treatment with 320 mg ethanolic extract of Serenoa repens proved to be efficient in reducing urinary obstruction, improving symptomatology and QoL of BPH patients. It also had a positive effect on sexual function, demonstrated by the statistically significant increase in the IIEF.

RESUMEN

PURPOSE: Indocyanine green (ICG) is being used more and more in Urology along with advances in minimal invasive surgery, guiding excision and reconstruction, highlighting anatomic structures and functional features with oncologic guidance still being debatable. The purpose of this paper was to explore ICG use in urologic procedures. METHODS: We present our experience (37 cases) of using ICG fluorescence guidance in urologic operations performed using 3D laparoscopy and FireFly® fluorescence imaging mode of Da Vinci X robot. The operations were the following: pelvic lymphadenectomy in radical prostatectomy, totally intracorporeal orthotopic ileal neobladder reconstruction, vesicovaginal fistula repair, partial nephrectomy and pyeloplasty. Barnard's test was used to compare postoperative complications (digestive fistula, ureteral stricture) for totally intracorporeal ileal neobladders performed with (group e, 27 cases) vs. without (group 2, 28 cases) ICG guidance. RESULTS: ICG under near-infrared fluorescence offered a precise identification of ischemic structures- vaginal wall, distal ureteral end, ileal loop, along with vascularized tissues allowing an optimal pyeloplasty and nephron sparing surgery with partial unclamping. It also allowed the identification of a lymph node during radical prostatectomy that otherwise would not have been excised during the routinely performed pelvic lymphadenectomy. There were no complications of ICG usage and the complication rate (digestive fistula, ureteral strictures) was significantly lower (p=0.002716) for group 1 compared with group 2. CONCLUSIONS: ICG facilitates the identification of key elements (anatomy and pathological structures) in the laparoscopic and robotic treatment of both malignant and benign urologic diseases, with possible impact on perioperative complications, along with oncologic and functional postoperative outcomes.

RESUMEN

Background: Prostate cancer (PCa) remains one of the leading causes of cancer-related mortality in men worldwide, mainly due to unsatisfactory diagnostic methods used at present, which lead to overdiagnosis, unnecessary biopsies and treatment, or misdiagnosis in early asymptomatic stages. New diagnostic biomarkers are needed for a correct and early diagnosis. Long noncoding RNAs (lncRNAs) have been broadly studied for their involvement in PCa biology, as well as for their potential role as diagnostic biomarkers. Methods: We conducted lncRNA profiling in plasma and microdissected formalin-fixed paraffin-embedded (FFPE) tissues of PCa patients and attempted validation for commonly dysregulated individual lncRNAs. Results: Plasma profiling revealed eight dysregulated lncRNAs, while microarray analysis revealed 717 significantly dysregulated lncRNAs, out of which only nuclear-enriched abundant transcript 1 (NEAT1) was commonly upregulated in plasma samples and FFPE tissues. NEAT1's individual validation revealed statistically significant upregulation (FC = 2.101, p = 0.009). Receiver operating characteristic (ROC) analysis showed an area under the curve (AUC) value of 0.7298 for NEAT1 (95% CI = 0.5812-0.8785), suggesting a relatively high diagnostic value, thus having a potential biomarker role for this malignancy. Conclusions: We present herein data suggesting that NEAT1 could serve as a diagnostic biomarker for PCa. Additional studies of larger cohorts are needed to confirm our findings, as well as the oncogenic mechanism of NEAT1 in the development of PCa.

RESUMEN

Colon cancer is the third most common cancer type worldwide and is highly dependent on DNA mutations that progressively appear and accumulate in the normal colon epithelium. Mutations in the TP53 gene appear in approximately half of these patients and have significant implications in disease progression and response to therapy. miR-125b-5p is a controversial microRNA with a dual role in cancer that has been reported to target specifically TP53 in colon adenocarcinomas. Our study investigated the differential therapeutic effect of miR-125b-5p replacement in colon cancer based on the TP53 mutation status of colon cancer cell lines. In TP53 mutated models, miR-125b-5p overexpression slows cancer cells' malignant behavior by inhibiting the invasion/migration and colony formation capacity via direct downregulation of mutated TP53. In TP53 wild type cells, the exogenous modulation of miR-125b-5p did not significantly affect the molecular and phenotypic profile. In conclusion, our data show that miR-125b-5p has an anti-cancer effect only in TP53 mutated colon cancer cells, explaining partially the dual behavior of this microRNA in malignant pathologies.
