RESUMEN

INTRODUCTION: While many questionnaire surveys have been undertaken worldwide to investigate practices toward deep carious lesion (DCL) management in adults, very few are related to children and adolescents. The present cross-sectional study aimed to assess DCL management in children and adolescents among dentists practicing paediatric dentistry in France (Fr-DPPDs). The secondary objective was to compare practices between Fr-DPPDs and dentists registered in the European Academy of Paediatric Dentistry (EAPD). METHODS: A questionnaire was electronically administrated to members of the CEOP (Collège des Enseignants en Odontologie Pédiatrique), the SFOP (Société Française d'Odontologie Pédiatrique), and the EAPD. Descriptive analyses, Chi-square and McNemar tests, ANOVA, crude and adjusted binary logistic regression analyses were performed. RESULTS: A total of 99 Fr-DPPDs and 146 EAPD members answered the questionnaire. Among the Fr-DPPDs, the preferred caries removal (CR) methods were the complete CR in one step for primary teeth and mature permanent teeth (respectively, 70% and 48%) and in two steps for immature permanent teeth (39%). EAPD members were more likely, than Fr-DPPDs, to choose selective CR versus complete CR in primary teeth (odds ratio = 2.60; 95% CI 1.39-4.85). Moreover, for primary or immature permanent teeth, general practitioners were less likely to choose selective CR than specialists and exclusive practitioners in paediatric dentistry, (p < 0.001). CONCLUSION: Tooth type [primary, permanent (immature or mature)] seemed to influence DCL management. Fr-DPPS should prioritise pulpal vitality when managing DCL.

RESUMEN

PURPOSE: Questionnaire surveys have been undertaken worldwide to investigate practices and knowledge related to carious lesion management, particularly in adults. The primary objective of this cross-sectional survey was to investigate restorative thresholds (RTs) used for carious lesions in primary molars by dentists practising paediatric dentistry in France. Dentists were surveyed by a specifically developed questionnaire based on clinical and radiographic caries classifications. The secondary objective was to explore restorative management strategies in primary molars. METHODS: A structured questionnaire assessing RTs and management strategies for occlusal and approximal carious lesions of primary molars was anonymously and electronically administered via SurveyMonkey® to dentists who were members of the Société Française d'Odontologie Pédiatrique. Descriptive analyses, Chi-square test, McNemar test, and logistic regression analyses considering dependent RT variables for occlusal and approximal carious lesions were performed. RESULTS: Among 250 dentists surveyed, 201 responded (response rate 80.4%). Overall, 43% (n = 87) and 75% (n = 151) of respondents would place their RTs in enamel for occlusal and approximal lesions, respectively. Dentists with an exclusive practice of paediatric dentistry more frequently would choose a RT in dentine for approximal lesions than did other dentists (p = 0.010). A preparation technique including sound dental tissues was less frequent for occlusal than approximal lesions (n = 31; 15% vs n = 60; 30%). Overall, 75% (n = 151) of respondents used the same restorative material for occlusal and approximal lesions. CONCLUSION: In general, dentists practising paediatric dentistry in France overtreated lesions on primary molars, which contradicts minimal intervention recommendations. RTs are too often indicated for enamel-confined carious lesions.

RESUMEN

PURPOSE: The intermediate-risk (IR) prostate cancer (PCa) group is heterogeneous in terms of prognosis. For unfavorable or favorable IR PCa treated by radiotherapy, the optimal strategy remains to be defined. In routine practice, the physician's decision to propose hormonal therapy (HT) is controversial. The PROACT survey aimed to evaluate pattern and preferences of daily practice in France in this IR population. MATERIALS AND METHODS: A web questionnaire was distributed to French radiotherapy members of 91 centers of the Groupe d'Etude des Tumeurs Uro-Genitales (GETUG). The questionnaire included four sections concerning: (i) the specialists who prescribe treatments and multidisciplinary decisions (MTD) validation; (ii) the definition of IR subsets of patients; (iii) radiotherapy parameters; (iv) the pattern of practice regarding cardiovascular (CV) and (iv) metabolic evaluation. A descriptive presentation of the results was used. RESULTS: Among the 82 responses (90% of the centers), HT schedules and irradiation techniques were validated by specific board meetings in 54% and 45% of the centers, respectively. Three-fourths (76%) of the centers identified a subset of IR patients for a dedicated strategy. The majority of centers consider PSA>15 (77%) and/or Gleason 7 (4+3) (87%) for an unfavorable IR definition. Overall, 41% of the centers performed systematically a CV evaluation before HT prescription while 61% consider only CV history/status in defining the type of HT. LHRH agonists are more frequently prescribed in both favorable (70%) and unfavorable (98%) IR patients. Finally, weight (80%), metabolic profile (70%) and CV status (77%) of patients are considered for follow-up under HT. CONCLUSION: To the best of our knowledge, this is the first survey on HT practice in IR PCa. The PROACT survey indicates that three-quarters of the respondents identify subsets of IR-patients in tailoring therapy. The CV status of the patient is considered in guiding the HT decision, its duration and type of drug.

RESUMEN

BACKGROUND: Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. OBJECTIVE: To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management. DESIGN: A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts before voting during a consensus conference. SETTING: Online Delphi survey and consensus conference. PARTICIPANTS: The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Statements were ranked by experts according to their level of agreement: 1-3 (disagree), 4-6 (equivocal), 7-9 (agree). A priori (level 1) consensus was defined as ≥70% agreement and ≤15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus). RESULTS AND LIMITATIONS: Overall, 116 statements were included in the Delphi survey. Of these, 33 (28%) statements achieved level 1 consensus and 49 (42%) statements achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease and the evolving role of checkpoint inhibitor therapy in metastatic disease. CONCLUSIONS: These consensus statements provide further guidance on controversial topics in advanced and variant bladder cancer management until a time where further evidence is available to guide our approach.

RESUMEN

BACKGROUND: The management of carious lesions in children and adolescents can have lifelong implications for the patient. The aim of this study was to assess the decision-making process of dentists when managing carious lesions in children and adolescents. METHODS: Approximately, 11 000 dentists listed as members of the Australian Dental Association Inc. (ADA) and Australian and New Zealand Society of Paediatric Dentistry (ANZSPD) were emailed a link in April 2017 to a 19-question survey delivered by SurveyMonkey™. RESULTS: In this study, 887 responses were received. In 'enamel-limited' carious lesions, dentists intervened most frequently in primary tooth approximal (365, 41.1%), followed by permanent tooth occlusal (295, 33.3%) and approximal (244, 27.5%), and primary tooth occlusal (203, 22.9%) surface carious lesions. Age, university of graduation, practicing state, decade of graduation and frequency of treatment of children between 6 and 15 years were significant demographic factors influencing the restorative threshold. CONCLUSIONS: Australian dentists reported significant variation in their management of approximal and occlusal carious lesions in both primary and permanent teeth. A substantial proportion of respondents would intervene surgically on non-cavitated enamel-limited lesions.

RESUMEN

AIM: To assess the validity and reliability of a recent light fluorescence device, Soprolife® (Sopro-Acteon group) in detecting occlusal caries in children and adolescents and to compare its diagnostic performance with DIAGNOPen® (Kavo). METHODS: A multi-centre study was carried out to validate Soprolife® in 103 children, aged from 5-15 years, on 310 primary and 433 permanent posterior teeth. The sensitivity (SE), specificity (SP) and the area under the Receiver Operating Characteristic (ROC) curve (AUC) were evaluated using visual International Caries Detection and Assessment System (ICDAS) and radiographic examinations as the gold standards. The performance of the Soprolife® was compared with that of the DIAGNOPen® on the same teeth. The reproducibility was assessed using weighted Kappa coefficient. RESULTS: When all carious lesions using ICDAS 1-6 were considered, SE, SP and AUC for the Soprolife® were 88.50, 70.73 and 0.84 respectively. The validity was significantly higher for primary teeth (AUC = 0.90) than for permanent teeth (0.80); the validity of the Soprolife® (0.84) was significantly higher than that of DIAGNOPen® (0.80). The inter- and intra-examiner kappa coefficients were 0.87 and 0.85 respectively. CONCLUSION: The Soprolife® was a valid instrument providing reproducible results, particularly for primary teeth.

RESUMEN

AIM: To assess dental practice regarding the use of indirect pulp capping or pulpotomy in children with deep carious lesions approaching the pulp in primary teeth and to compare the efficacy of the two pulp treatments. STUDY DESIGN: Systematic review. We searched the Cochrane Library, PubMed via MEDLINE, and EMBASE as well as the reference lists of included reports and ClinicalTrials.gov (for ongoing trials). Eligible studies were surveys of dental practice sent to dentists regarding the use of indirect pulp capping and pulpotomy in children with deep carious lesions approaching the pulp in primary teeth and any type of clinical study. Two review authors independently extracted data and assessed risk of bias in duplicate. RESULTS: Of the 481 potentially eligible articles, 11 were included in the review: 8 described surveys of dental practice, 1 a non-randomised study, and 2 ongoing randomised trials. The surveys of dental practice showed an overall increase in the teaching and practice of indirect pulp capping in primary teeth. The non- randomised study found a statistically significant difference in favour of indirect pulp capping for clinical and radiological success at 3 years but with high overall risk of bias. CONCLUSIONS: Despite the success rate of indirect pulp capping for treating deep carious lesions approaching the pulp in primary teeth, practitioners still hesitate to practice this technique because of lack of evidence and studies on this topic. Thus, for strong evidence, investigators are encouraged to conduct randomised trials comparing the efficacy of indirect pulp capping and pulpotomy for treating deep carious lesions approaching the pulp in primary teeth.

RESUMEN

OBJECTIVE: Transcutaneous spinal direct current stimulation (tsDCS) modulates spinal cord pain pathways. The study is aimed to clarify the neurophysiology of the tsDCS-induced modulation of the spinal cord pain processing by evaluating the effect of the tsDCS on temporal summation threshold (TST) of the nociceptive withdrawal reflex (NWR). METHODS: In a randomized, double-blind, crossover study the effects of anodal, cathodal and sham tsDCS (2 mA, 15 min) applied on the skin overlying the thoracic spinal cord were investigated in 10 healthy subjects. RESULTS: Anodal tsDCS induced a long-lasting (up to 60 min) increase in TST of the NWR as well as a parallel decrease in related psychophysical temporal summation of pain, while cathodal and sham tsDCS resulted ineffective. CONCLUSIONS: Anodal tsDCS represents a non-invasive tool able to induce an early and long-lasting depression of the transitory facilitation of the wide dynamic range neurons activity at the basis of both the temporal summation of the NWR and the related temporal summation of pain sensation. SIGNIFICANCE: The modulation of the temporal processing of nociceptive stimuli could be effective in treating clinical pain conditions in which pain is generated by spinal cord structures.

RESUMEN

BACKGROUND: Chronic migraine (CM) has a high impact on functional performance and quality of life (QoL). CM also has a relevant burden on the National Health Service (NHS), however precise figures are lacking. In this pilot study we compared the impact in terms of costs of CM and episodic migraine (EM) on the individual and on the National Health System (NHS). Furthermore, we comparatively evaluated the impact of CM and EM on functional capability and on QoL of sufferers. METHODS: We enrolled 92 consecutive patients attending the Pavia headache centre: 51 subjects with CM and 41 with episodic migraine (EM). Patients were tested with disability scales (MIDAS, HIT-6, SF-36) and with an ad hoc semi-structured questionnaire. RESULTS: The direct mean annual cost (in euro) per patient suffering from CM was €2250.0 ± 1796.1, against €523.6 ± 825.8 per patient with EM. The cost loaded on NHS was €2110.4 ± 1756.9 for CM, €468.3 ± 801.8 for EM. The total economic load and the different sub-items were significantly different between groups (CM vs. EM p = 0.001 for each value). CM subjects had higher scores than EM for MIDAS (98.4 ± 72,3 vs 15.5 ± 17.7, p = 0.001) and for HIT-6 (66.1 ± 8.4 vs 58.7 ± 10.1, p = 0.001). The SF-36 score was 39.9 ± 14,74 for CM and 66.2 ± 18.2 for EM (p = 0.001). CONCLUSIONS: CM is a disabling condition with a huge impact on the QoL of sufferers and a significant economic impact on the NHS. The adequate management of CM, reverting it back to EM, will provide a dual benefit: on the individual and on the society.

RESUMEN

PURPOSE: To report survival and morbidity of a cohort of 200 hormone-naïve consecutive patients with localized prostate cancer, treated by low-dose rate brachytherapy within the frame of multidisciplinary approach. PATIENTS AND METHODS: Between 2001 and 2011, 200 patients were treated by the same team with 125 iodine seeds: 167 low-risk and 33 intermediate risk according to the d'Amico classification; eligible patients had clinical stage T1/T2a-b, Gleason score 3+3 or 3+4, baseline prostate-specific antigen level below 15ng/mL, prostate volume less than 60cm(3). The median number of random biopsies was 12 (range 6-32) and the breakdown of positive cores was as follows: 1 (29%), 2 (35%), 3 or more (36%). Acute morbidity was assessed according to the Common Terminology Criteria for Adverse Events and late toxicity according to the EORTC/RTOG scale. Data were prospectively collected. RESULTS: The median follow-up was 69 months (range 16 to 135). The 5- and 10-year biochemical relapse free survivals were 95.6% (95% confidence interval [CI]: 91-98) and 89.7% (95% CI: 79.4-95.0). The 5-year and 10-year overall survival were respectively 96.4% (95% CI: 92-98.4) and 89.7% (95% CI: 80.8-94.6%) and the 10-year disease specific survival, 99.1% (95% CI: 93.0-99.9). The 5- and 10-year grade 3 acute toxicity cumulative rate were respectively 3.3% (95% CI: 1.4-6.6) and 4% (95% CI: 1.4-6.6) and the 5- and 10-year grades 3 cumulative late toxicity 2.5% (95% CI: 2.0-5.9) and 4% (95% CI: 2.0-5.9). CONCLUSION: Brachytherapy managed within the frame of a multidisciplinary approach - from diagnosis to evaluation - may offer optimized results with a reduced late toxicity rate, while remaining opened to dosimetry and technical improvements.

RESUMEN

Even in the current era of dose-escalated radiotherapy for prostate cancer, biochemical recurrence is not uncommon. Furthermore, biochemical failure is not specific to the site of recurrence. One of the major challenges in the management of prostate cancer patients with biochemical failure after radiotherapy is the early discrimination between those with locoregional recurrence only and those with metastatic disease. While the latter are generally considered incurable, patients with locoregional disease may benefit from emerging treatment options. Ultimately, the objective of salvage therapy is to control disease while ensuring minimal collateral damage, thereby optimizing both cancer and toxicity outcomes. Advances in functional imaging, including multiparametric prostate MRI, abdominopelvic lymphangio-MRI, sentinel node SPECT-CT and/or whole-body PET/CT have paved the way for salvage radiotherapy in patients with local recurrence, microscopic nodal disease limited to the pelvis or oligometastatic disease. These patients may be considered for salvage reirradiation using different techniques: prostate low-dose or high-dose rate brachytherapy, pelvic and/or lomboaortic image-guided radiotherapy with elective nodal irradiation, focal nodal or bone stereotactic body radiation therapy (SBRT). An individualized approach is recommended. The decision about which treatment, if any, to use will be based on the initial characteristics of the disease, relapse patterns and the natural history of the rising prostate specific antigen (PSA). Preliminary results suggest that more than 50% of patients who have undergone salvage reirradiation are biochemically relapse-free with very low rates of severe toxicity. Large prospective studies with a longer follow-up are needed to confirm the promising benefit/risk ratio observed with salvage brachytherapy and or salvage nodal radiotherapy and/or bone oligometastatic SBRT when compared with life-long palliative hormones.

RESUMEN

BACKGROUND: Breast cancer is one of the most common malignancies in women. Genome-wide association studies have identified FGFR2 as a breast cancer susceptibility gene. Common variation in other fibroblast growth factor (FGF) receptors might also modify risk. We tested this hypothesis by studying genotyped single-nucleotide polymorphisms (SNPs) and imputed SNPs in FGFR1, FGFR3, FGFR4 and FGFRL1 in the Breast Cancer Association Consortium. METHODS: Data were combined from 49 studies, including 53 835 cases and 50 156 controls, of which 89 050 (46 450 cases and 42 600 controls) were of European ancestry, 12 893 (6269 cases and 6624 controls) of Asian and 2048 (1116 cases and 932 controls) of African ancestry. Associations with risk of breast cancer, overall and by disease sub-type, were assessed using unconditional logistic regression. RESULTS: Little evidence of association with breast cancer risk was observed for SNPs in the FGF receptor genes. The strongest evidence in European women was for rs743682 in FGFR3; the estimated per-allele odds ratio was 1.05 (95% confidence interval=1.02-1.09, P=0.0020), which is substantially lower than that observed for SNPs in FGFR2. CONCLUSION: Our results suggest that common variants in the other FGF receptors are not associated with risk of breast cancer to the degree observed for FGFR2.

RESUMEN

BACKGROUND: Most cases of beer allergy reported so far have been associated with hypersensitivity to the non-specific lipid transfer protein (LTP). In view of the marked differences in brewing processes we assessed IgE reactivity as well as tolerance to many different beers in an allergic patient. METHODS: A 45 year-old man hypersensitive to grass pollen, cat dander and Alternaria tenuis with a history of urticaria and dyspnoea after drinking beer and a weak skin reactivity to commercial corn extract was studied. The patient underwent SPT with 36 different brands of beer and an open challenge with those scoring negative was performed. An immunoblot analysis was carried out using 2 SPT-positive beers, 2 SPT-negative beers, and barley, wheat, and maize extracts using both patient's serum and a maize LTP-specific in-house developed polyclonal antibody from rabbit. Further, the immune reactive LTP of one beer was separated by HPLC and the chromatogram was compared to that of purified maize LTP. RESULTS: Beer SPT scored positive in 30/36 cases. The immunoblot analysis showed IgE reactivity at about 10 kDa against the two SPT-positive beers and against maize with both patient's serum and the polyclonal anti-LTP rabbit serum, whereas the two SPT-negative beers, and barley extract scored negative. The immunodetected protein co-migrated with maize LTP. CONCLUSION: In beer-allergic patients the diagnostic workup may point to the detection of some tolerated products that can be consumed risk-free.

RESUMEN

AIM: We investigated the prognostic significance of intraductal carcinoma of the prostate (IDC-P) in biopsies and transurethral resections prior to external beam radiotherapy with or without androgen deprivation. METHODS: Cohort 1 consisted of 118 intermediate risk prostate cancer patients treated by radiotherapy, with biochemical relapse as primary end-point (median follow-up 6.5 years). Cohort 2 consisted of 132 high risk patients, enrolled in a phase III randomised trial (EORTC 22863) comparing radiotherapy alone to radiotherapy with long-term androgen deprivation (LTAD) with clinical progression free survival as primary end-point (median follow-up 9.1 years). Presence of IDC-P was identified after central review. Multivariable regression modelling and Kaplan-Meier analysis were performed with IDC-P as dichotomous variable. RESULTS: IDC-P was a strong prognosticator for early (<36 months) biochemical relapse (HR 7.3; p = 0.007) in cohort 1 and for clinical disease-free survival in both arms of cohort 2 (radiotherapy arm: HR 3.5; p < 0.0001; radiotherapy plus LTAD arm: HR 2.8, p = 0.018). IDC-P retained significance after stratification for reviewed Gleason score in the radiotherapy arm (HR 2.3; p = 0.03). IDC-P was a strong prognosticator for metastatic failure rate (radiotherapy arm: HR 5.3; p < 0.0001; radiotherapy plus LTAD arm: HR 3.6; p = 0.05). CONCLUSIONS: IDC-P in diagnostic samples of patients with intermediate or high risk prostate cancer is an independent prognosticator of early biochemical relapse and metastatic failure rate after radiotherapy. We suggest that the presence of IDC-P in prostate biopsies should routinely be reported.

RESUMEN

BACKGROUND: Evaluation of caries status has changed with emergence of modified ways of managing the condition. There is a need to assess the relationship between the old and new methods of registering caries. OBJECTIVE: To identify the ICDAS II codes to be used to record the D-component of the DMF index as defined in the WHO Basic Methods, 1997 publication. METHOD: A review of literature published between January 2002 and January 2012 was undertaken using "ICDAS" as keyword in an electronic search. Only epidemiological studies that used ICDAS II as an evaluation criterion calculated the DMF indices and gave the ICDAS II codes for the diagnosis of caries lesions, were included. RESULTS: Fourteen studies met the inclusion criteria. The DMF designations that corresponded with the WHO definition were D(3-6)MF (10 studies), D(4-6)MF (4 studies) or D(5-6)MF (3 studies). The D-component referred to cavitated carious lesions (7 studies) or dentine caries (7 studies), but there was no consensus on the ICDAS II codes that are used to define them. Only the ICDAS II codes 5 and 6 had unanimous support; they were always counted as "Caries", but there was less certainty for codes 3 and 4. The only study on fields that compared both methods showed D(3-6) to be the always associated with the D-component of the DMF index as defined in the WHO Basic Methods. CONCLUSION: There was disagreement of the ICDAS II codes to be used for the DMF calculation; and when there was a need to compare DMF values between studies, the diagnosis threshold should be verified to be the same.

RESUMEN

The combination of radiotherapy and androgen suppression with luteinizing hormone releasing hormone agonist has become a standard of care for locally advanced prostate cancer. Phase III randomized trials have shown that for locally advanced prostate cancer a 4-month complete androgen blockade initiated 2 months prior radiotherapy and stopped at the completion of radiotherapy increased overall survival in patients with Gleason score 2-6, meanwhile an adjuvant long term androgen suppression (2.5-3 years) improved significantly overall survival.

RESUMEN

AIM: To describe the dental health status of 6-year-old children using the ICDAS-II advanced method and to evaluate the association between the known caries risk factors with the cavitated caries lesion (WHO basic method) or with both non-cavitated and cavitated caries lesion caries (ICDAS II). METHODS: In this cross-sectional study, a questionnaire was used to evaluate oral health and dietary habits of children. A clinical examination and a Cario analysis test (Pierre Fabre Oral care) were performed. STATISTICS: Logistic regression analyses were used to assess the association between caries and daily tooth-brushing, dietary habits, visible plaque and salivary factors. RESULTS: There were 341 children (52% female and 6.25+/-0.46 years of age) in this study. Using the ICDAS-II advanced method, 39% of the children were caries-free. This proportion was larger (67.2%) using the WHO method. In multivariate models, visible dental plaque and Streptococcus mutans count were associated with caries experience registered as ICDAS-II codes 1-6 or codes 3-6. The absence of daily tooth-brushing with fluoridated toothpaste was associated only with caries experience ICDAS-II codes 3-6. CONCLUSION: The use of WHO or ICDAS-II method changed the proportion of caries-free children but not the clinical caries risk factors associated with caries experience.

RESUMEN

OBJECTIVE: Our aim was to present a summary of the 2010 version of the European Association of Urology (EAU) guidelines on the screening, diagnosis, and treatment of clinically localised cancer of the prostate (PCa). METHODS: The working panel performed a literature review of the new data emerging from 2007 to 2010. The guidelines were updated, and level of evidence and grade of recommendation were added to the text based on a systematic review of the literature, which included a search of online databases and bibliographic reviews. RESULTS: A full version is available at the EAU office or Web site (www.uroweb.org). Current evidence is insufficient to warrant widespread population-based screening by prostate-specific antigen (PSA) for PCa. A systematic prostate biopsy under ultrasound guidance and local anaesthesia is the preferred diagnostic method. Active surveillance represents a viable option in men with low-risk PCa and a long life expectancy. PSA doubling time in < 3 yr or a biopsy progression indicates the need for active intervention. In men with locally advanced PCa in whom local therapy is not mandatory, watchful waiting (WW) is a treatment alternative to androgen-deprivation therapy (ADT) with equivalent oncologic efficacy. Active treatment is mostly recommended for patients with localised disease and a long life expectancy with radical prostatectomy (RP) shown to be superior to WW in a prospective randomised trial. Nerve-sparing RP represents the approach of choice in organ-confined disease; neoadjuvant androgen deprivation demonstrates no improvement of outcome variables. Radiation therapy should be performed with at least 74Gy and 78Gy in low-risk and intermediate/high-risk PCa, respectively. For locally advanced disease, adjuvant ADT for 3 yr results in superior disease-specific and overall survival rates and represents the treatment of choice. Follow-up after local therapy is largely based on PSA, and a disease-specific history with imaging is indicated only when symptoms occur. CONCLUSIONS: The knowledge in the field of PCa is rapidly changing. These EAU guidelines on PCa summarise the most recent findings and put them into clinical practice.
