Diagnóstico incidental del cáncer de vejiga en España. Estudio observacional a nivel nacional / Incidental diagnosis of bladder cancer in a national observational study in Spain

Introducción El cáncer de vejiga (CV) es una neoplasia frecuente en España. Los objetivos de este estudio fueron: identificar la proporción de pacientes diagnosticados de CV de forma incidental o tras la presentación de síntomas en un periodo contemporáneo en España; comparar las características demográficas, clínicas y patológicas entre estos grupos. Métodos El presente fue un análisis retrospectivo de un estudio observacional multicéntrico realizado en 26 hospitales del Sistema Nacional de Salud español, incluyendo a todos los nuevos diagnósticos de CV en 2011. El estudio representó 21,5% de la población española y los hospitales fueron seleccionados de forma proporcional a las regiones españolas para asegurar una muestra representativa. Los pacientes fueron categorizados según el diagnóstico de cáncer incidental o tras la presentación sintomática y se analizaron las características demográficas, patológicas y clínicas basales. Resultados En los 26 hospitales españoles incluidos en el estudio, se diagnosticaron 2.472 casos de CV, de los cuales 308 (12,5%) fueron diagnosticados de forma incidental y 2.164 (87,5%) tras la presentación de síntomas. No se observaron diferencias entre los pacientes diagnosticados incidentalmente frente a los sintomáticos en términos demográficos o de comorbilidades evaluadas. En comparación con los tumores de vejiga con diagnostico posterior a la presentación de síntomas, los diagnósticos incidentales tenían más probabilidades de ser tumores papilares, significativamente más pequeños y de tener una citología positiva/sospechosa. Además, los tumores de vejiga diagnosticados incidentalmente tenían menos probabilidades de ser músculo-invasivos (11,7 vs. 25%, p < 0,01) y de ser agresivos en el estudio patológico, con 33,6% de grado 3 vs. 50,1% (p < 0,01). Conclusiones Identificamos un porcentaje significativo (12,5%) de nuevos diagnósticos de CV realizados de forma incidental en una muestra representativa de la población española (AU)

Introduction Bladder cancer (BC) is a common malignancy in Spain. The aims of this study were: to identify the proportion of patients diagnosed with BC incidentally or after symptomatic presentation in a contemporary period in Spain; to compare demographic, clinical, and pathologic characteristics between these groups. Methods This was a retrospective analysis of a multi-centre observational study of 26 hospitals in the Spanish National Health System of all BCs newly diagnosed in 2011. The study represented 21.5% of the Spanish population and hospitals were selected in proportion to Spain's regions to ensure a representative sample. Patients were categorized by whether the cancer was diagnosed incidentally or after symptomatic presentation and baseline demographic, pathologic, and clinical characteristics were analyzed. Results 2472 were newly diagnosed with BC at the 26 participating Spanish hospitals with 308 (12.5%) of cases diagnosed incidentally and 2164 (87.5%) diagnosed after symptomatic presentation. No differences were observed between patients diagnosed incidentally vs. symptomatically in terms of demographics or measured co-morbidities. Compared to symptomatically diagnosed bladder tumours, those diagnosed incidentally were more likely to have a papillary appearance, to be significantly smaller, and less likely to have positive/suspicious cytology. Additionally, incidentally diagnosed bladder tumours were less likely to be muscle-invasive (11.7% vs. 25.0%, P < .01) nor aggressive at pathology, with 33.6% Grade 3 compared to 50.1%, (P < .01). Conclusions We identified a significant percentage (12.5%) of new bladder cancer diagnosis made incidentally in a representative sample of the Spanish population. These tumours exhibited less aggressive pathologic characteristics than their symptomatic counterparts (AU)

Genetic variants of antioxidant enzymes and environmental exposures as molecular biomarkers associated with the risk and aggressiveness of bladder cancer.

Bladder cancer (BC) is one of the top 10 most common tumours worldwide; however, no molecular markers are currently available for tumour management and follow-up. BC could benefit from molecular biomarkers in environmental disease, which provide mechanistic understanding of individual susceptibility to exposure-related cancers and allow characterizing genetic alterations in the molecular pathway for malignancy. This case-control study performed a molecular analysis in 99 BC and 125 controls. Buccal swabs were collected to assess SNPs in eleven genes coding for xenobiotic detoxification enzymes, cellular antioxidant defences, and hormone synthesis and signalling (NAT2 (rs1801280), GPX1 (rs1050450 and rs17650792), TXNRD1 (rs7310505), PRDX3 (rs3740562), PON1 (rs662), SOD1 (rs10432782), SOD2 (rs4880), CAT (rs1001179), CYP17A1 (rs743572) and ESR1 (rs746432)). A structured questionnaire was administered to study participants to assess environmental and dietary chemical exposures. Several miRNAs associated with BC and detoxification/antioxidant pathways were analysed in a subsample of the study population, including miR-93-5p, miR-221-3p, miR-126, miR-27a-3p, miR-193b, and miR-193a-5p. Levels of selected environmental pollutants (polycyclic aromatic hydrocarbons and endocrine disrupting chemicals) were determined in urine from a subsample of BC cases and controls. We found that CYP17A1, CAT, SOD1, ESR1, PON1, and GPX1 (rs17650792) were associated with BC risk. Furthermore, exposure to smoke and/or dust, and alcohol intake were identified as risk factors for BC. Increased urinary levels of benzo[a]pyrene and bisphenol A were observed in BC patients relative to controls, along with an increased expression of miR-193b, miR-27a and miR-93-5p in BC. Nevertheless, further studies with a larger sample size are warranted to confirm these exploratory results. This study also shows that the combination of genetic markers (PON1 and CYP17A1) and miRNA (miR-221-3p and miR-93-5p) open a new scenario in the use of non-invasive biomarkers in the stratification of BC to guide personalized medicine, which is extremely urged in the current clinical setting.

The role of prostate-specific antigen in light of new scientific evidence: An update in 2020. / Papel del antígeno prostático específico ante las nuevas evidencias científicas, una nueva actualización en 2020.

OBJECTIVE: To review and update the latest scientific evidence gathered in recent years regarding prostate-specific antigen (PSA) for better implementation into routine clinical practice. EVIDENCE ACQUISITION: Analysis of the available evidence on the current role of PSA, based on the experience of an expert panel in the subject under analysis. EVIDENCE SYNTHESIS: Currently, PSA cannot be considered only as a guide for the presence or absence of prostate cancer. This determination can also help the urologist to decide on the most convenient treatment for a patient with benign prostatic hypertrophy (BPH) as a criterion for disease progression, and it can also suggest the suspicious existence of a prostatic tumor when there is PSA rise of>0.3 ng/ml over the level reached 6 months after having initiated treatment with 5-alpha-reductase inhibitor. However, the limits of this PSA rise with derivatives of alternative 5-alpha-reductase (5-ARI) inhibitors to dutasteride are controversial. Moreover, PSA is a key factor for the follow-up of patients with prostate adenocarcinoma at any stage who have received treatment (surgery, radiotherapy or focal therapies, hormone therapy), it acts as a guide to identify biochemical recurrence, to suspect the existence of local or distant recurrence, as well as to propose or discard adjuvant treatments. Finally, the role of PSA as a screening tool has been recently reinforced, demonstrating increased mortality rates or the existence of more aggressive cases of prostate cancer in those countries where the use of this tool has declined. CONCLUSIONS: We present new data about the current role of PSA in the management of patients treated for BPH and/or prostate cancer that should be implemented into routine clinical practice, with special emphasis on the relevant role of this biomarker in the screening and follow-up of prostate cancer, as well as in the progression of BPH in dutasteride treatment.

Androgen deprivation therapy in patients with localized disease: Comparison with curative intent treatments and time to castration resistance. Results of the Spanish Prostate Cancer Registry. / Terapia de privación de andrógenos en pacientes con enfermedad localizada: comparación de las opciones de tratamiento y tiempo hasta la resistencia a la castración. Resultados del Registro Español de Cáncer de Próstata.

BACKGROUND: The effect of primary androgen deprivation therapy (ADT) in patients with localized prostate cancer (PCa) has not been well documented. The objective of the present study was to analyze the outcome of tumors treated with ADT as primary therapy in the Spanish Prostate Cancer Registry (19.4% of the series). PATIENTS AND METHODS: Patients were classified in three groups: 1) with low/intermediate risk clinically localized tumors; 2) with high risk and locally advanced (T3-4) tumors; 3) with metastatic tumors. Time to castration resistance and overall cancer-specific survival were analyzed. In non-metastatic tumors, survivals in patients treated with ADT were compared with data from patients who underwent local treatments from the Spanish Prostate Cancer Registry. RESULTS: 703 cases were analyzed. There were significant differences in the time to castration resistance, which was lower in the group of metastatic tumors. During follow-up, there were 179 deaths (25.5%) of which 89 (12.6%) were due to PCa. After 3 years of ADT, only 14.6% of patients in group 1 had died (1% due to PCa), 20.5% in group 2 and 46.8% in group 3 (9.2% and 31.3% due to PCa, respectively). Cancer-specific survival was significantly worse in group 1 using ADT than radical prostatectomy or radiotherapy. In high-risk and locally advanced tumors, ADT also had a lower cancer-specific survival than local treatments. CONCLUSION: A longer time until the castration resistance was observed in patients with well- and intermediate-risk localized tumors treated with ADT. Patients with metastatic tumors showed the shortest time to castration resistance.

Impact of oxidative stress SNPs and dietary antioxidant quality score on prostate cancer.

Purpose: To analyse the relation between antioxidant genotypes and Dietary Antioxidant Quality score (DAQs) effect on prostate cancer (PCa) risk and aggressiveness in a Spanish population.Methods: Men (N = 155 patients and 152 controls) with PSA values >4 ng/ml were enrolled in the project. DAQs were used considering the daily recommended intake for Spanish people (DRI). Genotyping of 5 SNPs rs662 (PON1), rs10432782 (SOD1), rs4880 (SOD2), rs17650792 (GPX1) and rs1001179 (CAT) were included for the analysis.Results: rs17650792 was statistically significant between case and controls subjects. When comparing D´Amico risk, we found that rs662 (CC), rs10432782 (G allele) and rs17650792 (GG) confer a protection. When testing SNP-antioxidant nutrients interactions, we found an intake of vitamin A and rs100179 (T carriers) and selenium and rs17650792 (G carriers) confers a protection of being in low risk classification.Conclusions: We reported by the first time a correlation between rs662 (PON1) and PCa aggressiveness.

The role of miRNAs as biomarkers in prostate cancer.

There is an urged need of non-invasive biomarkers for the implementation of precision medicine. These biomarkers are required to these days for improving prostate cancer (PCa) screening, treatment or stratification in current clinical strategies. There are several commercial kits (Oncotype DX genomic prostate score®, Prolaris®, among others) that use genomic changes, rearrangement or even non-coding RNA events. However, none of them are currently used in the routine clinical practice. Many recent studies indicate that miRNAs are relevant molecules (small single-stranded non-coding RNAs that regulate gene expression of more than 30% of human genes) to be implement non-invasive biomarkers. However, contrasting to others tumors, such as breast cancer where miR-21 seems to be consistently upregulated; PCa data are controversial. Here we reported an extended revision about the role of miRNAs in PCa including data of AR signaling, cell cycle, EMT process, CSCs regulation and even the role of miRNAs as PCa diagnostic, prognostic and predictive tool. It is known that current biomedical research uses big-data analysis like Next Generation Sequencing (NGS) analysis. We also conducted an extensive online search, including the main platforms and kits for miRNAs massive analysis (like MiSeq, Nextseq 550, or Ion S5™ systems) indicating their pros, cons and including pre-analytical and analytical issues of miRNA studies.

Three-year interim results of overall and progression-free survival in a cohort of patients with prostate cancer (GESCAP group). / Resultados preliminares de supervivencia global y libre de progresión a tresaños en una cohorte de pacientes diagnosticados de cáncer de próstata (grupo GESCAP).

AIMS: To describe the 3-year progression-free survival (PFS), overall survival (OS) and disease-specific mortality in the prospective prostate cancer GESCAP cohort, as well as the progression to castration resistance in patients on hormone therapy. MATERIAL AND METHODS: Prospective, observational, epidemiological, multicentre study. Of the 4087 patients recruited, 3843 were evaluable. The variables analysed were the risk group (localized, locally advanced, lymph involvement, metastatic), age, prostate-specific antigen (PSA) levels, Gleason score and initial treatment. Kaplan Meier survival analysis, the log-rank test and the Cox model were used to evaluate the survival data. RESULTS: Three-year PFS was 81.4% and OS was 92.4%. During the 3 years of follow-up, 303 patients died (7.9%), 110 of them (36.3%) due to disease-related causes. The probability of castration resistance for all patients on hormone therapy (n=715) was 14.2%: 5%, 9.9%, 26.1% and 44.4% in localized, locally advanced, lymph involvement and metastatic cancer, respectively (log-rank P<.0001). Patients with metastases had poorer outcomes with respect to PFS, OS, disease-specific mortality and castration resistance. In the multivariate analysis, the Gleason score, PSA and presence of metastases were associated with shorter OS and PFS. CONCLUSIONS: Our study showed stratification of risk, with a more unfavourable prognosis for patients with metastases. Patients with locally advanced disease differed with respect to those with localized disease due to their higher risk as regards disease-specific mortality. (Controlled-trials.com ISRCTN19893319).

Genetic markers a landscape in prostate cancer.

Prostate cancer (PC) is one of the most common cancers worldwide. The observed variability in progression and responses to the same treatment between patients underlie the genetic heterogeneity of the disease. Nowadays, screening and follow-up biomarkers in PC are still having a deep lack of information, which makes difficult the cancer diagnosis, prognosis and the selection of the most suitable therapies. This is making that currently unnecessary biopsies, over-treatments and hormonoresistances have high rates of prevalence among patients. New biomarkers are urgently needed and in this sense genomic biomarkers could be the most suitable tools. These genetic markers will be helpful for improving the precision of prognostic and the predictive current tools which are employed in the clinical practice. A recent literature search up was conducted, including clinical trials and pre-clinical basic research studies. Keywords included germline variants, prostate cancer, biomarkers, androgen deprivation therapy, screening and liquid biopsy; among others. We have reviewed how germline variants, CNVs and repetitive regions are relevant to prostate carcinogenesis, treatment and progression. Moreover, we have also considered novel biomarkers for PC prognosis based on differentially expressed genes. Finally, we have included new strategies in recent markers of liquid biopsy or updated technologies for minimal samples analysis. The improvement of genetic markers use and their application to the clinical practice, will enhance the variability of simple, non-invasive, tools such as liquid biopsy and germline variants, these will reduce the number of PC needle biopsies and current over-treatments that are usual in the management of this cancer.

National recommendations document on the follow-up of patients with renal cell carcinoma. / Documento nacional de recomendaciones sobre el seguimiento del paciente con carcinoma de células renales.

OBJECTIVES: This document was developed to establish directives for the follow-up of patients with renal cell carcinoma (RCC) based on the best available scientific evidence and on expert opinions, which can help urologists in the decision-making process and standardise the criteria at the national level. MATERIAL AND METHODS: The methodology is based on the RAND/UCLA method. A panel of 9 experts on RCC participated in designing a thematic index, identifying and reading the available evidence, formulating recommendations and drafting the content. A validating group of 25 experts, who did not participate in the previous phases, assessed the recommendations through anonymous voting in a face-to-face consensus meeting. The recommendations that were agreed upon by 75% or more of the participants in this vote were accepted as consensus. The recommendations that did not achieve this consensus were rejected. RESULTS: A total of 25 recommendations were accepted as consensus. These recommendations cover the laboratory tests, clinical assessment tests and imaging tests that should be performed for patients with RCC. The presented recommendations have been adapted according to relapse risk. The current document also outlines the frequency and duration of follow-up for each patient profile. CONCLUSIONS: The current document enables standardisation of the follow-up criteria for patients with RCC treated in the Spanish healthcare setting, according to the patients' relapse risk.

Diagnosis and treatment for clinically localized prostate cancer. Adherence to the European Association of Urology clinical guidelines in a nationwide population-based study - GESCAP group. / Diagnóstico y tratamiento del cáncer de prostata clínicamente localizado. Adherencia a las guías clínicas en un estudio poblacional nacional ­ GESCAP.

OBJECTIVE: To assess the adherence to European Association of Urology (EAU) guidelines in the management of prostate cancer (PCa) in Spain. PATIENTS AND METHODS: Epidemiological, population-based, study including a national representative sample of 3,918 incident patients with histopathological confirmation during 2010; 95% of the patient's sample was followed up for at least one year. Diagnosis along with treatment related variables (for localized PCa -low, intermediate, high and locally-advanced by D'Amico risk stratification) was recorded. Differences between groups were tested with Chi-squared and Kruskal-Wallis tests. RESULTS: Mean (SD) age of PCa patients was 68.48 (8.18). Regarding diagnostic by biopsy procedures, 64.56% of all patients had 8-12 cores in first biopsy and 46.5% of the patients over 75 years, with PSA<10ng/mL were biopsied. Staging by Computer Tomography (CT) or Bone Scan (BS) was used for determining tumor extension in 60.09% of high-risk cases and was applied differentially depending on patients' age; 3,293 (84.05%) patients received a treatment for localized PCa. Radical prostatectomy was done in 1,277 patients and 206 out of these patients also had a lymphadenectomy, being 4.64% low-risk, 22.81% intermediate-risk and 36.00% high-risk patients; 86.08% of 1,082 patients who had radiotherapy were treated with 3D or IMRT and 35.77% received a dose ≥75Gy; 419 patients were treated with brachytherapy (BT): 54.81% were low-risk patients, 22.84% intermediate-risk and 12.98% high-risk. Hormonotherapy (HT, n=521) was applied as single therapy in 9.46% of low-risk and 17.92% of intermediate-risk patients. Additionally, HT was combined with RT in 14.34% of lower-risk patients and 58.26% of high-risk patients, and 67.19% low-intermediate risk with RT and/or BT received neoadjuvant/concomitant/adjuvant HT. Finally, 83.75% of high-risk patients undergoing RT and/or BT also received HT. CONCLUSIONS: Although EAU guidelines for PCa management are easily available in Europe, the adherence to their recommendations is low, finding the highest discrepancies in the need for a prostate biopsy and the diagnostic methods. Improve information and educational programs could allow a higher adherence to the guidelines and reduce the variability in daily practice. (Controlled-trials.com: ISRCTN19893319).

Somatic Mutations in Prostate Cancer: Closer to Personalized Medicine.

The molecular cause of prostate cancer (PCa) is still unclear; however, its progression involves androgen, PI3K/Akt, and PTEN signaling, as cycle and apoptotic pathways. Alterations in oncogenes and tumor suppressor genes as PIK3CA, BRAF, KRAS and TP53 are not very common. Recently, somatic mutations have been discovered in relation to cancer progression mainly in genes such as PIK3CA; however, little data has been described in PCa. Nowadays genetic tools allow us to investigate multiple details about the biological heterogeneity of PCa, to better understand the mechanisms of disease progression and treatment resistance. Therefore, if the most relevant somatic mutations were included during screening, we could identify the best treatment for the right patient, bringing us closer to personalized medicine. The main objective of this article is to provide a review of the principal somatic mutations that appear to have a relevant role in hormonal cancers, like prostate cancer.

Myopodin methylation is a prognostic biomarker and predicts antiangiogenic response in advanced kidney cancer.

Myopodin is a cytoskeleton protein that shuttles to the nucleus depending on the cellular differentiation and stress. It has shown tumor suppressor functions. Myopodin methylation status was useful for staging bladder and colon tumors and predicting clinical outcome. To our knowledge, myopodin has not been tested in kidney cancer to date. The purpose of this study was to evaluate whether myopodin methylation status could be clinically useful in renal cancer (1) as a prognostic biomarker and 2) as a predictive factor of response to antiangiogenic therapy in patients with metastatic disease. Methylation-specific polymerase chain reactions (MS-PCR) were used to evaluate myopodin methylation in 88 kidney tumors. These belonged to patients with localized disease and no evidence of disease during follow-up (n = 25) (group 1), and 63 patients under antiangiogenic therapy (sunitinib, sorafenib, pazopanib, and temsirolimus), from which group 2 had non-metastatic disease at diagnosis (n = 32), and group 3 showed metastatic disease at diagnosis (n = 31). Univariate and multivariate Cox analyses were utilized to assess outcome and response to antiangiogenic agents taking progression, disease-specific survival, and overall survival as clinical endpoints. Myopodin was methylated in 50 out of the 88 kidney tumors (56.8 %). Among the 88 cases analyzed, 10 of them recurred (11.4 %), 51 progressed (57.9 %), and 40 died of disease (45.4 %). Myopodin methylation status correlated to MSKCC Risk score (p = 0.050) and the presence of distant metastasis (p = 0.039). Taking all patients, an unmethylated myopodin identified patients with shorter progression-free survival, disease-specific survival, and overall survival. Using also in univariate and multivariate models, an unmethylated myopodin predicted response to antiangiogenic therapy (groups 2 and 3) using progression-free survival, disease-specific, and overall survival as clinical endpoints. Myopodin was revealed hypermethylated in kidney cancer. Myopodin methylation status identified which patients showed a more aggressive clinical behavior and predicted antiangiogenic response. These observations support the clinical utility of an unmethylated myopodin as a prognostic and predictive biomarker in kidney cancer.

Association between single-nucleotide polymorphisms in DNA double-strand break repair genes and prostate cancer aggressiveness in the Spanish population.

BACKGROUND: Novel predictors of prognosis and treatment response for prostate cancer (PCa) are required to better individualize treatment. Single-nucleotide polymorphisms (SNPs) in four genes directly (XRCC5 (X-ray repair complementing defective repair in Chinese hamster cells 5) and XRCC6 (X-ray repair complementing defective repair in Chinese hamster cells 6)) or indirectly (PARP1 and major vault protein (MVP)) involved in non-homologous end joining were examined in 494 Spanish PCa patients. METHODS: A total of 22 SNPs were genotyped in a Biotrove OpenArray NT Cycler. Clinical tumor stage, diagnostic PSA serum levels and Gleason score at diagnosis were obtained for all participants. Genotypic and allelic frequencies were determined using the web-based environment SNPator. RESULTS: (XRCC6) rs2267437 appeared as a risk factor for developing more aggressive PCa tumors. Those patients carrying the GG genotype were at higher risk of developing bigger tumors (odds ratio (OR)=2.04, 95% confidence interval (CI) 1.26-3.29, P=0.004), present higher diagnostic PSA levels (OR=2.12, 95% CI 1.19-3.78, P=0.011), higher Gleason score (OR=1.65, 95% CI 1.01-2.68, P=0.044) and D'Amico higher risk tumors (OR=2.38, 95% CI 1.24-4.58, P=0.009) than those patients carrying the CC/CG genotypes. Those patients carrying the (MVP) rs3815824 TT genotype were at higher risk of presenting higher diagnostic PSA levels (OR=4.74, 95% CI 1.40-16.07, P=0.013) than those patients carrying the CC genotype. When both SNPs were analyzed in combination, those patients carrying the risk genotypes were at higher risk of developing D'Amico higher risk tumors (OR=3.33, 95% CI 1.56-7.17, P=0.002). CONCLUSIONS: We believe that for the first time, genetic variants at XRCC6 and MVP genes are associated with risk of more aggressive disease, and would be taken into account when assessing the malignancy of PCa.

Treatment trends for clinically localised prostate cancer. National population analysis: GESCAP group. / Tendencias de tratamiento en el cáncer de próstata clínicamente localizado. Análisis poblacional a nivel nacional: grupo GESCAP.

OBJECTIVES: To describe the established therapies for localised prostate cancer (PC) in Spain and to assess compliance with the 2010 UAE guidelines. PATIENTS AND METHODS: This was an epidemiological, observational, prospective and multicentre study. Of the 3,918 patients diagnosed with PC during 2010, only those patients with localised PC were included. Follow-up was ultimately conducted for a minimum of one year from the diagnosis for 3,713 patients (94.77%). The treatment groups assessed were as follows: radical prostatectomy, radiation therapy, hormone therapy, brachytherapy, active surveillance or observation and experimental local treatment (cryotherapy or other treatment). Compliance with the recommendations of the EAU guidelines was studied, describing the treatment groups according to D'Amico risk stratification criteria (localised [low, intermediate and high risk] and locally advanced), age, PSA and Gleason score. RESULTS: By applying the D'Amico criteria, we included 3,641 (92.93%) patients. Based on the UAE recommendations: 1) 68.87% of the patients at low-intermediate risk aged≤65 years underwent radical prostatectomy; 2) 34.51% of the patients>65 years at high risk with locally advanced disease were administered radiation therapy and hormone therapy; 3) 30.36% of the patients at high risk with locally advanced disease were only treated with hormone therapy; 4) 15.20% of the patients at low risk were only treated with brachytherapy; 5) active surveillance or observation was selected for 2.44% of the patients aged≤65 years and for 10.63% of the patients at low-intermediate risk who were>65 years. Lastly, 86.5% of the patients at low risk underwent a single treatment, and 43.62% of the patients at high risk with locally advanced disease underwent combined treatments. CONCLUSIONS: This is the first national European study to evaluate the therapeutic management of localised PC based on the risk group to which the patient belonged. Most young patients (≤65 years) with low-intermediate risk localised PC were treated with surgery, which adheres to the recommendations of the 2010 UAE guidelines. Various therapeutic combinations have been employed for patients with high-risk, locally advanced localised tumours, revealing the need for a multidisciplinary approach (Controlled-trials.com number: ISRCTN19893319).

Recommendations for the Diagnosis and Management of Bladder Pain Syndrome. Spanish Urological Association Consensus Document.

INTRODUCTION: Bladder Pain Syndrome/Interstitial Cystitis (BPS/IC) and other bladder pathologies share common manifestations, such as the presence of mictional symptoms and a negative impact on the patient's quality of life. To be properly diagnosed and clinically managed, it is important to distinguish between its clinical modalities and diagnostic criteria for adequate exclusion. OBJECTIVE: The purpose of this study was to standardize criteria for making decisions in BPS management, for its diagnosis, initial treatment and follow-up. MATERIAL AND METHOD: A nominal group methodology was employed, using scientific evidence on BPS taken from a systematic (non-exhaustive) literature review for developing recommendations along with specialist expert opinions. RESULTS: The diagnosis of BPS should be made based on the patient's clinical history, with emphasis on pain and mictional symptoms as well as excluding other pathologies with similar symptomatology. BPS treatment should be directed towards restoring normal bladder function, preventing symptom relapse and improving patients' quality of life. It is therefore advisable to start with conservative treatment and to adopt less conservative treatments as the level of clinical severity increases. It is also recommended to abandon ineffective treatments and reconsider other therapeutic options. CONCLUSIONS: Quickly identifying the pathology is important when trying to positively influence morbidity and care quality for these patients.

Comparative analysis of the incidence of bladder cancer in the communities of Andalusia, Catalonia and Madrid in 2011.

OBJECTIVES: To determine the incidence of bladder cancer (BC) in the autonomous communities that include the largest number of cases in the national hospital BC registry (Andalusia, Catalonia and Madrid) and report the clinical, pathological and diagnostic differences and similarities of BC in these regions. MATERIAL AND METHODS: An observational epidemiological study was performed in 2011 in 12 public hospitals with reference population areas according to the National Health System (Spain). Demographic and clinical variables were collected from new cases and relapses, with histopathologic confirmation of BC. The raw incidence rate was calculated using the number of diagnosed cases in all the participating centers compared with the aggregate total population assigned to each center. The raw rates by age and sex were obtained from the National Institute of Statistics (2011) by weighting the assigned population with the distribution by age and sex. RESULTS: The 3 autonomous communities recorded 51% of the 4285 cases included in the national registration, with relapses corresponding to 42.8% of these cases. The raw annual incidence rate for new episodes was 22.6 (95% CI: 20.7; 24.6) in Andalusia, 23.5 (95% CI: 20.9; 26.0) in Catalonia and 22.0 (95% CI: 19.9; 24.1) in Madrid. CONCLUSIONS: Except for the larger proportion of smokers and lower tumor grade of lesions in Andalusia, the 3 autonomous communities studied are similar in terms of clinical characteristics, comorbidities, patient symptoms and diagnostic processes for BC.

Consensus document of the Spanish Urological Association on the management of uncomplicated recurrent urinary tract infections.

INTRODUCTION: The clinical manifestations of urinary infections, commonly mild and uncomplicated, have resulted in a generally empirical therapeutic decision-making process, which does not help fight resistances to antibacterial agents, thus causing a high rate of recurrence. OBJECTIVE: This study seeks to reduce the clinical variability in the diagnosis and treatment of uncomplicated recurrent urinary tract infections (RUTIs). MATERIAL AND METHOD: The consensus document was developed using a nominal group methodology, using scientific evidence on RUTIs extracted from a systematic (noncomprehensive) literature review, along with the expert judgment of specialists and their experience in clinical practice. RESULTS: RUTIs are considered the manifestation of at least 3 episodes of uncomplicated infection, with a positive culture in the past 12 months, in addition to (for men) the absence of structural or functional abnormalities. We maintain that the treatment should be empiric when suspecting RUTIs (prior to obtaining a urine sample for culture) in those patients who have a high probability of recurrence, associated risk factors and/or urinary or general symptoms, such as fever and chills. Homogeneous criteria are recommended for the diagnosis and treatment in order to fight the increased rates of resistance that the microorganisms develop against antimicrobial agents. CONCLUSION: Imprecision in the identification of the infection requires a search for agreements on homogenized criteria and decision algorithms that guide the management of these patients.
