MetSCORE: a molecular metric to evaluate the risk of metabolic syndrome based on serum NMR metabolomics.

BACKGROUND: Metabolic syndrome (MetS) is a cluster of medical conditions and risk factors correlating with insulin resistance that increase the risk of developing cardiometabolic health problems. The specific criteria for diagnosing MetS vary among different medical organizations but are typically based on the evaluation of abdominal obesity, high blood pressure, hyperglycemia, and dyslipidemia. A unique, quantitative and independent estimation of the risk of MetS based only on quantitative biomarkers is highly desirable for the comparison between patients and to study the individual progression of the disease in a quantitative manner. METHODS: We used NMR-based metabolomics on a large cohort of donors (n = 21,323; 37.5% female) to investigate the diagnostic value of serum or serum combined with urine to estimate the MetS risk. Specifically, we have determined 41 circulating metabolites and 112 lipoprotein classes and subclasses in serum samples and this information has been integrated with metabolic profiles extracted from urine samples. RESULTS: We have developed MetSCORE, a metabolic model of MetS that combines serum lipoprotein and metabolite information. MetSCORE discriminate patients with MetS (independently identified using the WHO criterium) from general population, with an AUROC of 0.94 (95% CI 0.920-0.952, p < 0.001). MetSCORE is also able to discriminate the intermediate phenotypes, identifying the early risk of MetS in a quantitative way and ranking individuals according to their risk of undergoing MetS (for general population) or according to the severity of the syndrome (for MetS patients). CONCLUSIONS: We believe that MetSCORE may be an insightful tool for early intervention and lifestyle modifications, potentially preventing the aggravation of metabolic syndrome.

[Background historical views of systemic treatment for muscle invasive bladder cancer.] / Perspectiva histórica del tratamiento sistémico del cáncer de vejiga músculo invasivo.

OBJECTIVES: Bladder cancer is a frequent, chemosensitive disease and has shown good outcomes on several chemotherapy regimens over last 60 years. However, very little improvement has been shown in terms of overall survival and side-effects decrease. EVIDENCE ACQUISITION: A review on manuscripts published in English and Spanish from 1949 including the terms chemotherapy and bladder cancer has been performed. EVIDENCE SYNTHESIS: Locally advanced or metastatic bladder cancer chemotherapy was initially introduced for metastasis management. The utilization of cisplatin base regimens has shown superiority over single therapy. The most commonly used regimens are cisplatine-metotrexate-vinblastine, metotrexate-vinblatine-adriamicine-cisplatin y gemcitabine-cisplatin. Neoadjuvant chemotherapy has shown to provide a minimal overall survival advantage, based on level 1 evidence. Neoadjuvant chemotherapy utilizes the same cisplatin-based regimens. Neoadjuvant chemotherapy is underutilized due to the inability to identify non-responders. Adjuvant chemotherapy is more controversial due to the lack of strong evidence. It is used when neoadjuvant chemotherapy has been utilized and the cystectomy pathology report is locally advanced. The best outcomes are for low-volume node positive patients.In bladder preservation protocols (aiming to decreased morbidity associated with cystectomy and chemotherapy), several regimens have been utilized in combination with radiation therapy. No standardized treatmentis available as no comparisons with cystectomy have been done. CONCLUSION: Chemotherapy has been utilized for several decades in muscle invasive bladder cancer without any major survival improvements or decreaseon side-effects. That is the rational why the treatment regimen are widely different amongst groups without a standard treatment.

CONTEXTO: A pesar de que el tumor vesical es un proceso oncológico frecuente, ser quimiosensible y haber comunicado resultados con distintos quimioterápicos desde hace más de 60 años, pocos han sido los avances logrados en supervivencia global y disminución de efectos secundarios.ADQUISICIÓN DE LA EVIDENCIA: Se realiza una revisión de los artículos publicados en lengua españolae inglesa desde enero de 1949 con las palabras quimioterapia, cáncer y vejiga en cualquier campo de la publicación. SINTESIS DE LA EVIDENCIA: La quimioterapia en el cáncer localmente avanzado o metastásico fue la primera empleada para intentar hacer regresar las metásta-sis. El empleo de combinaciones basadas en cisplatino ha demostrado superioridad sobre la monoterapia. Los regímenes más utilizados son cisplatino-metotrexate-vinblastina, metotrexate-vinblastina-adriamicina-cisplatino y gemcitabina-cisplatino. Como quimioterapia neoadyuvante, su utilización, aunque la mejoría en supervivencia es modesta, está basada en niveles de altos evidencia. Los regímenes son los mismos que para el avanzado y la imposibilidad de diferenciar los respondedores de los resistentes a la quimioterapia ha hecho que esté infrautilizada. La aplicación de quimioterapia adyuvante tiene más controversia porque los niveles de evidencia no son tan robustos. Se emplea cuando no se ha tratado con quimioterapianeoadyuvante y en la pieza de cistectomía el estadío es avanzado y tiene mejores resultados cuando es N+ con poca carga tumoral. En la preservación de órgano, para intentar disminuir la morbimortalidad del tratamiento de neoadyuvancia más cistectomía considerado el tratamiento con mayor evidencia, se han empleado diversas drogas combinadas en general con radioterapia sin conseguir un estándar de tratamiento al no haber comparaciones con la cistectomía.CONCLUSIÓN: La quimioterapia utilizada desde hace varias décadas en los tumores músculo-infiltrantes de vejiga no ha conseguido grandes mejoras en supervivencia ni disminución de los efectos secundarios. Por este motivo los esquemas de tratamiento varían de unos grupos a otros sin que haya un estándar de tratamiento.

Integrative analysis of transcriptomics and clinical data uncovers the tumor-suppressive activity of MITF in prostate cancer.

The dysregulation of gene expression is an enabling hallmark of cancer. Computational analysis of transcriptomics data from human cancer specimens, complemented with exhaustive clinical annotation, provides an opportunity to identify core regulators of the tumorigenic process. Here we exploit well-annotated clinical datasets of prostate cancer for the discovery of transcriptional regulators relevant to prostate cancer. Following this rationale, we identify Microphthalmia-associated transcription factor (MITF) as a prostate tumor suppressor among a subset of transcription factors. Importantly, we further interrogate transcriptomics and clinical data to refine MITF perturbation-based empirical assays and unveil Crystallin Alpha B (CRYAB) as an unprecedented direct target of the transcription factor that is, at least in part, responsible for its tumor-suppressive activity in prostate cancer. This evidence was supported by the enhanced prognostic potential of a signature based on the concomitant alteration of MITF and CRYAB in prostate cancer patients. In sum, our study provides proof-of-concept evidence of the potential of the bioinformatics screen of publicly available cancer patient databases as discovery platforms, and demonstrates that the MITF-CRYAB axis controls prostate cancer biology.

[Radium 223 in castration resistant prostate cancer.] / Radio 223 en cáncer de próstata resistente a la castración.

OBJECTIVE: To analyze the available evidence on Radium 223 therapy, an alfa particle emitter with specific action on bone metastases, studied on patients with castration resistant prostate cancer. EVIDENCE ACQUISITION: We review the pivotal study ALSYMPCA, that served to get the drug approval for this phase of the disease, and the new data obtained from its use. We also performed a search of ongoing studies with Radium 223 alone or in combination with other molecules. EVIDENCE SINTHESIS: According to the ALSYMPCA study, Radium 223 significantly prolongs the overall survival of patients with castration resistant prostate cancer and bone metastases; approximately 3.6 months in comparison with patients who received placebo, which turns into a median life expectancy of 14.9 months, and a 36-month survival of 46%, associated with a 30% reduction in death risk. Overall survival results were consistent both in patients who receive Docetaxel previously and those who did not. RESULTS: for secondary variables support the positive effect of Radium 223 therapy on symptomatic skeletal events (for example, the use of external beam radiotherapy to alleviate pain) and bone markers, confirming its efficacy in bone metastases. CONCLUSIONS: Radium 223 is the first treatment directed to bone that has demonstrated significant improvement on overall survival. It also prolonged the time to the first skeletal event and the median time to PSA increase significantly. All this in addition to its manageable adverse effects, lower than those appeared in the placebo arm of the pivotal study ALSYMPCA.

OBJETIVO: Analizar la evidencia disponible del tratamiento con Radium-223, emisor de partículas alfa con acción específica sobre las metástasis óseas, estudiado en pacientes con cáncer de próstata resistente a la castración. Adquisición de la evidencia: Revisión del estudio pivotal ALSYMPCA, que sirvió para conseguir la aprobación del fármaco en esta fase de la enfermedad, y los nuevos datos obtenidos a partir del uso del mismo. También, hacer una búsqueda de los estudios en marcha con Radium-223, solo o en combinación con otras moléculas. Síntesis de la evidencia: Radium-223 según los resultados del estudio ALSYMPCA prolonga de forma significativa la supervivencia global en pacientes con cáncer de próstata resistente a la castración y metástasis óseas; aproximadamente 3,6 meses respecto a los tratados con placebo, lo que se traduce en una mediana de esperanza de vida de 14,9 meses, y una supervivencia a los 36 meses del 46% de los pacientes, asociado a una reducción del 30% en el riesgo de muerte. Los resultados de la variable supervivencia global, fueron consistentes tanto en pacientes que habían recibido previamente Docetaxel como en aquellos que no lo habían recibido. Los resultados de las variables secundarias apoyan el efecto positivo del tratamiento con Radium-223 en los eventos óseos sintomáticos (por ejemplo, el uso de la radioterapia externa para aliviar el dolor) y en los marcadores óseos, confirmando su eficacia en las metástasis óseas. CONCLUSIONES: Radium-223 es el primer tratamiento dirigido al hueso que ha demostrado mejoría significativa en supervivencia global. También prolongó de forma significativa, el tiempo hasta el primer evento óseo y la mediana de tiempo hasta aumento de PSA. Todo ello con unos efectos adversos manejables e inferiores a los producidos en el brazo placebo del estudio pivotal ALSYMCA

The metabolic co-regulator PGC1α suppresses prostate cancer metastasis.

Cellular transformation and cancer progression is accompanied by changes in the metabolic landscape. Master co-regulators of metabolism orchestrate the modulation of multiple metabolic pathways through transcriptional programs, and hence constitute a probabilistically parsimonious mechanism for general metabolic rewiring. Here we show that the transcriptional co-activator peroxisome proliferator-activated receptor gamma co-activator 1α (PGC1α) suppresses prostate cancer progression and metastasis. A metabolic co-regulator data mining analysis unveiled that PGC1α is downregulated in prostate cancer and associated with disease progression. Using genetically engineered mouse models and xenografts, we demonstrated that PGC1α opposes prostate cancer progression and metastasis. Mechanistically, the use of integrative metabolomics and transcriptomics revealed that PGC1α activates an oestrogen-related receptor alpha (ERRα)-dependent transcriptional program to elicit a catabolic state and metastasis suppression. Importantly, a signature based on the PGC1α-ERRα pathway exhibited prognostic potential in prostate cancer, thus uncovering the relevance of monitoring and manipulating this pathway for prostate cancer stratification and treatment.

Quality of life in patients with lower urinary tract symptoms associated with BPH: change over time in real-life practice according to treatment--the QUALIPROST study.

PURPOSE: To evaluate change in quality of life (QoL) and symptoms in patients with lower urinary tract symptoms/benign prostatic hyperplasia (LUTS/BPH) in conditions of current clinical practice. METHODS: Prospective, longitudinal, multicenter open-label study was carried out in urology outpatient clinics. Patients were ≥40 years of age with an International Prostate Symptom Score (IPSS) score ≥ 8. QoL and symptoms were measured at baseline and 6 months using the Benign Prostatic Hyperplasia Impact Index (BII) and the IPSS. RESULTS: 1713 patients were included for analysis. Mean (SD) IPSS and BII scores at baseline were 16.8 (5.4) and 6.8 (2.6), respectively. 8.9 % (n = 153) of study participants did not receive treatment (watchful waiting, WW), 70.3 % (n = 1204) were prescribed monotherapy (alpha-adrenergic blockers [AB]; phytotherapy [PT, of which 95.2 % was the hexanic extract of Serenoa repens, HESr]; or 5-alpha-reductase inhibitors [5ARI]), and 20.8 % (n = 356) received combined treatment (AB + 5ARI; AB + HESr; others). At 6 months, improvements in QoL were similar across the different medical treatment (MT) groups, both for monotherapy (AB: mean improvement [SD] of 2.4 points [2.4]; PT: 1.9 [2.4]; 5ARI: 2.5 [2.3]) and combined therapy (AB + 5ARI: 3.1 [2.9]; AB + PT: 3.1 [2.5]). There were no clinically significant differences between MT groups and all showed significant improvement over WW (p < 0.05). HESr showed similar efficacy to AB and 5ARI both as monotherapy and in combination with AB. Results on the IPSS were similar. CONCLUSIONS: Improvements in QoL and symptoms were equivalent across the medical treatments most widely used in real-life practice to manage patients with moderate or severe LUTS. HESr showed an equivalent efficacy to AB and 5ARI with fewer side effects.

A Pilot Study on the Potential of RNA-Associated to Urinary Vesicles as a Suitable Non-Invasive Source for Diagnostic Purposes in Bladder Cancer.

Bladder cancer is one of the most common cancers and, together with prostate carcinoma, accounts for the majority of the malignancies of the genitourinary tract. Since prognosis ameliorates with early detection, it will be beneficial to have a repertoire of diagnostic markers that could complement the current diagnosis protocols. Recently, cell-secreted extracellular vesicles have received great interest as a source of low invasive disease biomarkers because they are found in many body fluids, including urine. The current work describes a pilot study to generate an array-based catalogue of mRNA associated to urinary vesicles, and also a comparison with samples obtained from bladder cancer patients. After an analysis of presence/absence of transcripts in bladder cancer EVs, a list of genes was selected for further validation using PCR technique. We found four genes differentially expressed in cancer samples. LASS2 and GALNT1 were present in cancer patients, while ARHGEF39 and FOXO3 were found only in non-cancer urinary vesicles. Previous studies have pointed to the involvement of those genes in tumour progression and metastasis.

Key areas in the learning curve for robotic urological surgery: a Spanish multicentre survey.

BACKGROUND: The number of robotic-assisted procedures offered in Spain is rapidly increasing despite a lack of consensus criteria for training and credentialling. OBJECTIVE: This national multicentre study was designed to analyze the different areas of the robotic urological surgery learning curve. MATERIAL AND METHODS: A questionnaire was sent to all 13 urology units in Spain with an active robotics programme requesting information on training and problems encountered. RESULTS: In most centres (n = 11, 84.6%), training programmes were animal-based; cadavers were used at only 2 (15.4%). Proctoring in initial procedures was practiced by 12 groups (92.3%). When initiating the robotics programme, the console was shared at 8 units (61.5%). Prior experience in open and/or laparoscopic surgery was reported by 10 of the groups (76.9%), and experience in open surgery only by 2 (15.4%) or robotic surgery alone by 1 (7.7%). The procedure with which the robotics programme was started in all 13 participating units was radical prostatectomy. The number of cases needed to complete the learning curve for this procedure was 20-25 cases according to 8 (61.5%) surgery teams. CONCLUSIONS: Up until March 26, 2010, 1,692 operations, mostly radical prostatectomies, were conducted using the da Vinci robot in our country.

Hidatidosis pelviana como ejemplo de masas pelvianas de etiología dudosa / Pelvic hydatid disease as an example of pelvic masses of uncertain aetiology

Presentar dos nuevos casos de quiste hidatídico pelviano, uno con clínica de compresión local y otro asintomático. Varón de 75 años que refiere tenesmo, dificultad para la micción y defecación. Una ecografía revela que se trata de una gran masa quística pelviana que desplaza la vejiga y el rectosigma. La tomografía computarizada describe imágenes compatibles con hidatidosis y un quiste hidatídico hepático. Se interviene quirúrgicamente al paciente, y se extirpa parcialmente el quiste pelviano. El otro caso es un varón de 75 años que, en el estudio de HBP, se descubre de forma casual una hidatidosis pelviana. Se decide, al estar asintomático, vigilancia. La anatomía patológica confirma el diagnóstico en el primer caso y los hallazgos radiológicos, en el segundo. Ambos pacientes están asintomáticos. La posibilidad de hidatidosis se debe considerar en el diagnóstico diferencial de cualquier masa quística localizada en los órganos pelvianos, sobre todo en países donde la enfermedades endémica. Aunque no hay un test serológico con el 100% de especificidad, las pruebas radiológicas ayudan a confirmar el diagnóstico. La cirugía es el tratamiento de elección (AU)

We present two new cases of pelvic hydatid cysts, one with a clinical profile of local compression and the other one asymptomatic. The first case is a 75 year-old man who reported difficulty defecating and urinating. The ultrasound revealed a large cystic pelvic mass displacing the bladder and rectosigmoid region. Computed tomography also showed images compatible with hydatid disease and a hydatid liver cyst. The patient underwent a surgical procedure, and the pelvic cyst was partially excised. The other case is an asymptomatic 75 year-old man with pelvic hydatid disease that was discovered by chance while examining a prostatic adenoma. Because he is asymptomatic, we opted for observation. The anatomical pathology study confirmed the diagnosis in the first case and radiological findings confirmed the second. Both patients remain asymptomatic. Hydatid disease must be considered in the differential diagnosis for any cystic masses in the pelvic organs, especially in countries where the disease is endemic. Although no 100% specific serological test exists, there are some radiological procedures which can help us to confirm the disease. Surgery is the treatment of choice (AU)

[Inflammatory aortic aneurysm and its relationship to urological disease: a case report and a literature review]. / Aneurismas de aorta inflamatorios y su relación con la patología urológica: caso clínico y revisión de la literatura científica.

OBJECTIVE: To report a successfully treated case of inflammatory aortic aneurysm. MATERIALS AND METHODS: A 57-year-old patient reported low back pain and urinary infections. An abdominal CT scan revealed a large inflammatory aneurysm in the abdominal aorta. An aortic bypass was performed with no complications. RESULTS: Patient course since surgery has been uneventful, and currently has no symptoms. CONCLUSIONS: Contribution of the radiographic team, mainly with the CT scan, is of great value both for differential diagnosis and adequate management and follow-up. Surgery is indicated to prevent aneurysm rupture, but an increased postoperative morbidity and mortality should be assumed.

[Does a pT0 cystectomy specimen imply being tumour-free in the long term?]. / ¿Implica el T0 en la pieza de cistectomía encontrarse libre de tumor a largo plazo?

INTRODUCTION AND OBJECTIVES: The aim of this study was to evaluate the progress of patients with a pT0 radical cystectomy specimen in order to know what factors are helpful in deciding when the bladder can be preserved. MATERIAL AND METHODS: We reviewed 153 cases of radical cystectomies performed due to bladder tumours without neoadjuvant therapy between 1995 and 2005 and with a minimum of three years of follow-up. Stage pT0 patients were selected. We considered age at time of diagnosis, sex, pathological stage and grade of the tumour at the time of transurethral resection (TUR), number of resections, surgical factors, tumour characteristics (multifocal, papillary or solid), progression-free survival, cancer-specific survival and cause of death. We ran a univariate analysis of the different factors studied along with disease progression. RESULTS: 12.8% of cystectomy specimens were pT0N0. Progression occurred in 35% between 6 months and 4 years after the cystectomy. Cancer-specific survival was 75%. Five patients died within an average of 18 months. The cause of death for all of them was tumour progression with distant metastasis. Statistical studies in the univariate analysis were only related to progression and the number of prior TURs, which is probably due to the number of cases, but the tumour multifocality, grade and stage were noteworthy. 15% of the pT0 patients had a papillary phenotype and 33% of them died. Of those with a non-papillary phenotype, 23.5% died. CONCLUSIONS: A stage pT0N0 cystectomy specimen does not define this surgery as curative, and these cases require the same follow-up as for the rest of the patients. It is of particular interest that out of all of our cases, there was no local recurrence, but there was distant metastasis. This leads us to believe that these patients could have benefitted from systemic chemotherapy with no need for radical surgery. In our study, the number of previous relapses was the only prognostic factor with statistical significance.
