A meta-analysis and systematic review of randomized controlled trials with degarelix versus gonadotropin-releasing hormone agonists for advanced prostate cancer

Our aim was to systematically evaluate the benefits of degarelix as antagonist versus agonists of gonadotropin-releasing hormones (GnRH) for the treatment of advanced prostate cancer (PC). This comparison was performed either in terms of biochemical or oncological or safety profiles. To this end we, carried out a systematic review and meta-analysis of the literature.We selected only studies directly and prospectively analyzing the two treatments in the same population (randomized phase III studies). We followed the Preferred Reporting Items for Systematic Reviews and meta-analyses process for reporting studies.After we eliminated studies according to the exclusion criteria, 9 publications were considered relevant to this review. These articles described 5 clinical trials that were eligible for inclusion. The follow-up duration in all trials did not exceed 364 days. This meta-analysis and review comprised a total of 1719 men, 1061 randomized to degarelix versus 658 to GnRH agonists treatment for advanced PC. Oncological results were evaluated only in 1 trial (CS21:408 cases) and they were not the primary endpoints of the study. Treatment emerging adverse events were reported in 61.4% and 58.8% of patients in the degarelix and GnRH agonists group, respectively (odds ratio, OR = 1.17; 95% confidence interval, 95% CI: 0.78-1.77, P > 0.1). Treatment related severe cardiovascular side effects were reported (trial CS21-30-35) in 1.6% and 3.6% of patients in the degarelix and GnRH agonists group, respectively (OR = 0.55, 95% CI: 0.26-1.14, P > 0.1).Our analysis evidences relevant limitations in particular for the comparative evaluation of the efficacy and the oncological results related to degarelix

Loss of Renal Function After Retrograde Ureteral Placement of an Allium Stent for Severe Ureteral Stricture

Background: Ureteral strictures are a recurrent chronic condition that leads to severe side effects and poor quality of life. Management of ureteral stricture is a great challenge for urologists and no specific guidelines exist. Retrograde Allium®ureteral stent (AUS) is a newly developed ureteral stent to treat either bulbar urethral or ureteral stenosis. Case Presentation: We describe a case of a 74-year-old Caucasian adult male presenting with a severe ureteral stricture secondary to an ureteroscopy for stone disease. Treatment with retrograde AUS placement produced a complete loss of renal function after 36 months, probably because of the development of a long achalasic stretch of the ureter. Conclusions: AUS is a new and promising device for the treatment of ureteral stenosis. However, a lack of standardization of the technique recommends a close instrumental follow-up after the procedure to decide the optimal time for stent removal

Use of 3D T2-Weighted MR Sequences for the Assessment of Neurovascular Bundle Changes after Nerve-Sparing Radical Retropubic Prostatectomy (RRP): A Potential Diagnostic Tool for Optimal Management of Erectile Dysfunction after RRP

Erectile dysfunction (ED) is one of the complications after radical retropubic prostatectomy (RRP), and recovery of erectile function is quantitatively related to the preservation of the neurovascular bundles (NVBs). The aim of our study was to assess, in patients submitted to a nerve-sparing RRP, the capability of a dedicated 3D isotropic magnetic resonance imaging (MRI) T2-weighted sequence in the depiction of postsurgical changes of NVB formation. Fifty-three consecutive patients underwent a bilateral nerve-sparing RRP. Two postoperative magnetic resonance (MR) examinations and International Index of Erectile Function Five-Item (IIEF-5) questionnaire were carried out at 6 and 12 months. Morphological imaging of the postprostatectomy fossa was performed by first acquiring turbo spin echo T2-weighted sequences in the axial and coronal planes and then with 3D T2-weighted isotropic sequence on axial plane. Image findings were scored using a relative 5-point classification (0 = normal; I = mild; II = mild to moderate; III = moderate; IV = severe alterations) and correlated with postoperative IIEF-5 score questionnaire. The degree of association between the alteration score values obtained by postoperative MR morphologic evaluation for MR sequence and IIEF-5 score. Image interpretation was performed by two radiologists, that scoring MR alterations by the use of axial and multiplanar reconstruction 3D T2 isotropic sequence. The radiologists placed 43.30% of patients in class 0 (23/53 normal or quite normal), 32.00% in class I (17/53 mild), 11.40% in class II (6/53 mild to moderate), 7.50% in class III (4/53 moderate), and 5.70% in class IV (3/53 severe). In all cases, the correlation and regression analyses between the 3D T2 isotropic sequence and IIEF-5 score, resulted in higher coefficient values (rho = 0.45; P = 0.0010). The MRI protocol and NVB change classification score proposed in this study would represent an additional tool in the postoperative phase of those patients with ED.

Value of magnetic resonance spectroscopy imaging and dynamic contrast-enhanced imaging for detecting prostate cancer foci in men with prior negative biopsy

Purpose: This study aimed to prospectively analyze the role of magnetic resonance spectroscopy imaging (MRSI) and dynamic-contrast enhancement magnetic resonance (DCEMR) in the detection of prostate tumor foci in patients with persistently elevated prostate-specific antigen levels (in the range of >= 4 ng/mL to <10 ng/mL) and prior negative random trans-rectal ultrasound (TRUS)-guided biopsy. Experimental Design: This was a prospective randomized single-center study. One hundred and eighty eligible cases were included in the study. Patients in group A were submitted to a second random prostate biopsy, whereas patients in group B were submitted to a (1)H-MRSI-DCEMR examination and samples targeted on suspicious areas were associated to the random biopsy. Results: At the second biopsy, a prostate adenocarcinoma histologic diagnosis was found in 22 of 90 cases (24.4%) in group A and in 41 of 90 cases (45.5%) in group B (P = 0.01). On a patient-by-patient basis, MRSI had 92.3% sensitivity, 88.2% specificity, 85.7% positive predictive value (PPV), 93.7% negative predictive value (NPV), and 90% accuracy; DCEMR had 84.6% sensitivity, 82.3% specificity, 78.5% PPV, 87.5% NPV, and 83.3% accuracy; and the association MRSI plus DCEMR had 92.6% sensitivity, 88.8% specificity, 88.7% PPV, 92.7% NPV, and 90.7% accuracy, for predicting prostate cancer detection. Conclusions: The combination of MRSI and DCEMR showed the potential to guide biopsy to cancer foci in patients with previously negative TRUS biopsy. To avoid a potential bias, represented from having taken more samples in group B (mean of cores, 12.17) than in group A (10 cores), in the future a MRSI/DCEMR directed biopsy could be prospectively compared with a saturation biopsy procedure.

Characterization of circulating blood dendritic cell subsets DC123+ (lymphoid) and DC11C+ (myeloid) in prostate adenocarcinoma patients

PURPOSE. We verified whether prostate adenocarcinoma produces specific modifications in DC subsets count. METHODS. Twenty-one untreated prostate adenocarcinomas were divided on the basis of clinical stage in localized and metastatic disease. As control we used a population of 18 healthy male subjects. For DCs enumeration, peripheral blood (PB) samples were obtained in all cases. A single-platform flow cytometric assay based on Tru-COUNT was used for the enumeration of the two DCs subsets, myeloid (mDCs) and plasmacytoid (pDCs). RESULTS. We showed a statistically significant reduction in pDCs count in prostate cancer population when compared to healthy controls (P = 0.002). Comparing each clinical stage with healthy controls, significant differences were found between controls and the metastatic group in both pDCs and mDCs (P = 0.005 and P = 0.023 respectively) but not between controls and the localized group (P = 0.055 and P = 0.829 respectively). CONCLUSIONS. We showed that DCs count in PB is significantly affected by prostate adenocarcinoma progression in a metastatic disease. © 2006 Wiley-Liss, Inc

Il Barracuda si racconta: l'utilizzo di metodi di analisi narratologica, psicosociale e semiotica in criminologia clinica

Starting from the analysis of a fictional story written by an author of violent crimes repeatedly subjected to a psychiatric examination, this work aims to highlight the importance of studying the writings of criminals to "understand" the author of the story. In order to show the clinical-criminological usefulness of the analysis of the written productions of the perpetrators, we have subjected the narrative text produced by the subject to a cross-examination, reading it from the point of view of the content in the light of the history of the same available in the expert report, and subsequently analyzing it according to multiple methods of investigation (analysis according to the contributions of narrative criminology, psychodynamic analysis of the defenses according to the contributions of psychosocial criminology, semiotic analysis according to Barthes). All this in order to better understand the characteristics of the subject and to attempt an all-round description.The study of the offender's narratives allows us to better represent the conflict that leads to the passage to the violent act: the in-depth analysis of the narrative productions, both before and after the crime committed, highlights the traumatic moments and the delicate passages that precede the fall of the process of symbolization and the construction of a representation of the self and the other that sees violence as the only way out of an otherwise unmanageable situation.Partendo dall’analisi di un racconto di finzione scritto da un autore di reati violenti più volte sottoposto a perizia psichiatrica, questo lavoro si propone di evidenziare l’importanza dello studio degli scritti dei criminali per “comprendere” il soggetto autore della storia. Allo scopo di mostrare l’utilità clinico-criminologica dell’analisi delle produzioni scritte degli autori di reato, abbiamo sottoposto il testo narrativo prodotto dal soggetto a un esame incrociato, leggendolo dal punto di vista del contenuto alla luce della storia dello stesso reperibile nell’elaborato peritale, e successivamente analizzandolo secondo plurime metodiche di indagine (analisi secondo i contributi della criminologia narrativa, analisi psicodinamica delle difese secondo i contributi della criminologia psicosociale, analisi semiotica secondo Barthes). Tutto ciò al fine di comprendere meglio le caratteristiche del soggetto e di tentarne una descrizione a tutto tondo. Lo studio delle narrative del reo permette di meglio rappresentare il conflitto che conduce al passaggio all’atto violento: l’analisi approfondita delle produzioni narrative, sia precedenti che suc-cessive al reato commesso, evidenzia i momenti traumatici e i delicati passaggi che precedono la caduta del processo di simbolizzazione e la costruzione di una rappresentazione del sé e dell’alter che vede nella violenza l’unico modo per uscire da una situazione altrimenti ingestibile

Comparison of the clinical usefulness of different urinary tests for the initial detection of bladder cancer: a systematic review

Objectives: The standard initial approach in patients with hematuria or other symptoms suggestive of bladder cancer (BC) is a combination of cystoscopy and urine cytology (UC); however, UC has low sensitivity particularly in low-grade tumors. The aim of the present review was to critically analyze and compare results in the literature of promising molecular urinary tests for the initial diagnosis of BC. Methods: We searched in the Medline and Cochrane Library databases for literature from January 2009 to January 2019, following the PRISMAguidelines. Results: In terms of sensitivity, ImmunoCyt showed the highest mean and median value, higher than UC. All tests analyses showed higher mean and median sensitivity when compared with UC. In terms of specificity, only UroVysion and Microsatellite analyses showed mean and median values similar to those of UC, whereas for all other tests, the specificity was lower than UC. It is evident that the sensitivity of UC is particularly low in low grade BC. Urinary tests mainly had improved sensitivity when compared to UC, and ImmunoCyt and UroVysion had the highest improvement in low grade tumors. Conclusions: Most of the proposed molecular markers were able to improve the sensitivity with similar or lower specificity when compared to UC. However, variability of results among the different studies was strong. Thus, as of now, none of these markers presented evidences so as to be accepted by international guidelines for diagnosis of BC
