Is a Vaginectomy Enough or is a Pelvic Exenteration Always Required for Surgical Treatment of Recurrent Cervical Cancer? A Propensity-Matched Study.

PURPOSE: Reporting the perioperative and survival outcomes of vaginectomy with respect to a matched series of pelvic exenteration (PE) in women with isolated recurrent cervical cancer. METHODS: The records of vaginal recurrent cervical cancer patients admitted at Fondazione Policlinico "Agostino Gemelli" IRCCS in Rome from January 2010 to June 2019 were retrospectively analyzed. A propensity-matched score analysis was performed by age, clinical stage, disease-free interval, and R0 resection. Postsurgical complications and survival rates were evaluated. RESULTS: Fifteen women underwent vaginectomy, and 30 patients were submitted to PE. No statistical differences were observed between the two groups at baseline characteristics. The vaginectomy procedures were successfully performed in all women, and no case required conversion to PE. Moreover, a higher rate of major postoperative complications after PE with respect to vaginectomy (p = 0.027) was recorded. Among them, three women required reoperation within 30 postoperative days, and four experienced two or more complications. Twenty-five (55.6%) women experienced recurrence: 8 of 25 (32.0%) in the vaginectomy group, and 17 of 25 (68%) in the PE group, with a median progression-free survival of 20 months and 13 months, respectively (p = 0.169). In total, 5 of 15 (33.3%) died of disease in the vaginectomy group and 13/30 (43.3%) in the PE group, with a median overall survival of 39 and 18 months for vaginectomy and PE, respectively (p = 0.161). CONCLUSIONS: The vaginectomy seems to allow for salvage treatment, such as radiotherapy and/or PE, but with a minimal impact on the quality of life in appropriately selected women with local recurrent cervical cancer.

The impact of COVID-19 pandemic on urological emergencies: a single-center experience.

PURPOSE: COVID-19 pandemic represents a novel challenge for healthcare systems, and it affects even the daily urological practice. Italy was the first country after China to experience a lock-down period. Our objective is to determine whether, during the COVID-19 period, there has been any modification in urological emergencies. METHODS: we retrospectively reviewed urgent urological consultations requested by the Emergency Department (ED) of Padua University Hospital in the 36-day period between February 22nd and March 30th, 2020 and compared them to the prior year cases within a similar time frame (February 24th to March 31st, 2019). Pediatric population (age < 15 years); surgical complications and traumas were excluded to avoid confounding from the reduction of activities during the lockdown. The number of daily consultations, the number of invasive procedures performed and admissions were evaluated, together with the predictors of admission were identified through multivariate logistic regression models. RESULTS: The final sample resulted in 107 consultations performed in 2020 and 266 in 2019. A higher number of daily consultations was performed during 2019 (7.33 vs 2.97, p < 0.001). Similarly, the number of daily-invasive procedures was higher in 2019 (p = 0.006), while there was no difference in the number of daily admissions (15 vs 12, p = 0.80). On multivariate analysis, the year (2020 vs 2019, OR 2.714, 95% CI 1.096-6.757, p = 0.0297) was a significant predictor of admission. CONCLUSIONS: Urgent urology practice was affected during COVID-19 pandemic with a remarkable reduction in urgent urological consultations; furthermore, a higher risk of admissions was observed in 2020. The consequences of a potentially delayed diagnosis remain to be determined.

Morbidity, mortality, and quality assessment following open radical cystectomy in elderly patients with bladder cancer.

BACKGROUND: Open radical cystectomy (ORC) with pelvic lymph-node dissection (PLND) for bladder cancer (BCa) and urinary diversion is a morbid procedure, and advanced age has been associated with a higher incidence of Clavien-Dindo ≥ 3 complications. AIM: To investigate the association between chronological age, survival outcomes, incidence of perioperative complications, and quality parameters in patients undergoing ORC. METHODS: We reviewed 413 patients who underwent ORC and PLND at a single academic centre between December 2009 and June 2018 for cT2-T4N0M0 BCa. Complete clinical, demographic, and pathological data were collected in the preoperative, preoperative, and postoperative setting. Patients were categorized as ≥ 75 years or < 75 years and statistical analysis was performed accordingly. Besides descriptive statistics, Kaplan-Meier log-rank test was used. Cox regression univariate and multivariate analyses were used to assess any potential predictor of OS and CSS. RESULTS: There were 285 (69%) patients < 75 years and 128 (31%) patients ≥ 75 years old. There was no significant difference between the two age groups neither in terms of distribution of pathological stage nor in terms of overall incidence of postoperative complications. Chronological age was not significantly associated with survival outcomes on multivariate analysis. Finally, the comorbidity index was the only significant risk factor for the incidence of any complications (OR = 0.83, p = 0.002) at multivariate binary logistic regression. CONCLUSION: Open radical cystectomy (ORC) is a feasible and safe procedure in patients with high-risk non-metastatic bladder cancer. Uro-oncologists should consider evaluating elderly patients for surgery according to a thorough geriatric assessment despite chronological age.

Perioperative Mortality and Long-Term Survival after Radical Cystectomy: A Population-Based Study in a Southern European Country on 4,389 Patients.

PURPOSE: Population-based data on survival after radical cystectomy (RC) are lacking from Southern Europe. The aim of this study was to assess trends and determinants of perioperative mortality and long-term survival in the Veneto region (Northeastern Italy). METHODS: All patients submitted to RC for bladder cancer from January 2004 to December 2016 were identified from the regional archive of hospital discharge records. Age at surgery, gender, comorbidities, hospital volume, calendar period of surgery, and type of urinary diversion were retrieved; vital status and cause of death were obtained by linkage with mortality records. Determinants of 90-day mortality were assessed by multilevel logistic regression; long-term survival was investigated by the Kaplan-Meier method and Cox regression. RESULTS: Among 4,389 included patients, an increase in the share of patients aged ≥80 years (from 13% in 2004-2008 to 24% in 2013-2016, p < 0.001) and a decline in performing continent diversion (from 34.9 to 23.4%, p < 0.001) were observed across the study period. Ninety-day mortality did not change over time and was 4% for patients aged <70 years and 13.7% for those aged ≥80 years. Age- and comorbidities-adjusted mortality was significantly lower in hospitals performing >30 RCs/year (odds ratio 0.67, 95% confidence interval 0.48-0.93). At a median follow-up of 67 months, overall survival at 1 year and 5 years was 72 and 40%, respectively, with a higher rate among younger patients treated in high-volume hospitals. CONCLUSION: The population of patients treated with RC is rapidly ageing, with a high risk of perioperative and long-term mortality; this changing epidemiological scenario and better outcomes observed in high-volume hospitals support regionalization of the procedure.

The Bladder EpiCheck Test as a Non-Invasive Tool Based on the Identification of DNA Methylation in Bladder Cancer Cells in the Urine: A Review of Published Evidence.

Recently, there has been a great effort to develop tests based on non-invasive urinary biomarkers (NMIBCs). These tests are based on the fact that NMIBCs are heterogeneous at the molecular level and can be divided into different molecular groups useful to predict prognosis and response to treatment. The assessment of epigenetic alterations, such as DNA methylation, represents a promising cancer biomarker. DNA methylation is an epigenetic modification that affects gene expression without modifying the DNA sequence. Several studies have highlighted the presence of methylated loci in the context of bladder cancer, indicating its potential application as a diagnostic and prognostic biomarker. One of the novel assays based on a DNA methylation profile, the Bladder EpiCheck, analyzes DNA from spontaneous urine, detecting disease-specific DNA methylation patterns in bladder cancer patients. This test, due to its non-invasive nature and highly promising performance could, in future, become an invaluable tool in the follow-up of bladder cancer patients. Potential new applications could include diagnosis and surveillance of upper-tract disease, for the replacement of invasive testing and ureteroscopy.

The effects of androgen deprivation therapy on the 18F-Chcoline uptake in prostate cancer patients undergoing neoadjuvant treatment.

BACKGROUND: The aim of the present study was to evaluate how neoadjuvant androgen deprivation therapy (ADT) can impact 18F-choline uptake in primary prostate cancer (PC) and its metastases before radical prostatectomy (RP) or radiation therapy (RT). METHODS: We retrospectively reviewed images of 79 PC patients undergoing 18F-choline PET/CT before RP or RT. Based on concomitant administration of neoadjuvant ADT at the time of 18F-choline PET/CT, patients were subdivided into naïve group (Group 1) and neoadjuvant ADT group (Group 2). PET/CT results, SUVmax and metabolic tumor volume (MTV) for each site were re-assessed by two nuclear medicine physicians with more than 5 years of experience. A chi-square and a U-Mann Whitney test were used to compare the two groups. RESULTS: Sixty-two patients were included in Group 1, while 17 in Group 2. PET/CT was positive in all patients, in particular: 54 had a significant uptake in prostate alone, 12 in prostate plus lymph nodes (LN), 4 in prostate plus LN and bone, 3 in prostate plus bone and 6 in prostate plus other organs (such as lung or thyroid). PET/CT was more frequently positive in a different site, outside the prostate, in Group 1 as compared to Group 2 (P<0.001). Conversely, median SUVmax and MTV in the prostate resulted significantly lower in Group 2 than in Group 1 (5.34 vs. 7.72 and 3.66 vs. 6.86 cm3, respectively; both P<0.05). CONCLUSIONS: PET/CT could have an important role in prostate cancer staging before primary treatment; however, before imaging, hormonal therapy status should be carefully evaluated.

Does 1.5 T mpMRI play a definite role in detection of clinically significant prostate cancer? Findings from a prospective study comparing blind 24-core saturation and targeted biopsies with a novel data remodeling model.

BACKGROUND: Multiparametric-magnetic resonance imaging (mpMRI) can accurately detect high-grade and larger prostate cancers (PC). AIMS: To evaluate the ability of 1.5 T magnetic field mpMRI-targeted Prostate Biopsies (PBx) in predicting PC in comparison with blind 24-core saturation PBx (sPBx). METHODS: We prospectively collected data from patients undergoing transrectal sPBx and, if needed, targeted PBx of suspected lesions based on the 16-'region-of-interest' (ROI) PI-RADS graph. Data remodeling: for each 'target' (each suspected lesion at mpMRI), we identified all the 16 'ROIs' into which the lesion extended: these single 'ROIs' were identified as 'macro-targets'. For each 'ROI' and 'macro-target', we compared the mpMRI result with that of a saturation and targeted biopsy (if performed). RESULTS: 1.5T mpMRI showed a PI-RADS value ≥ 3 in 101 patients (82.1%). We found a PC in 50 (40.6%). Negative-positive predictive values for mpMRI were 82-45%, respectively. Of the 22 patients with normal mpMRI, four had a PC, but none had a clinically significant cancer. After the data remodeling, we demonstrated the presence of PC in 228 'ROIs': (a) only in targeted biopsies in 15 'ROIs'/'macro-targets' (6.6%); (b) only in sPBx in 177 'ROIs' (77.6%); (c) in both targeted and sPBx in 36 'ROIs' (15.8%). DISCUSSION: 81.8% of patients with normal 1.5T mpMRI were negative at PBx. Performing only targeted PBx may lead to lack of PC diagnosis in about 50% of patients. CONCLUSIONS: In patients with suspected PC and a previous negative PBx, a normal mpMRI may exclude a clinically significant PC, avoiding sPBx.

MALDI-TOF peptidomic analysis of serum and post-prostatic massage urine specimens to identify prostate cancer biomarkers.

BACKGROUND: Lower urinary tract symptoms (LUTS) and prostate specific antigen-based parameters seem to have only a limited utility for the differential diagnosis of prostate cancer (PCa). MALDI-TOF/MS peptidomic profiling could be a useful diagnostic tool for biomarker discovery, although reproducibility issues have limited its applicability until now. The current study aimed to evaluate a new MALDI-TOF/MS candidate biomarker. METHODS: Within- and between-subject variability of MALDI-TOF/MS-based peptidomic urine and serum analyses were evaluated in 20 and 15 healthy donors, respectively. Normalizations and approaches for accounting below limit of detection (LOD) values were utilized to enhance reproducibility, while Monte Carlo experiments were performed to verify whether measurement error can be dealt with LOD data. Post-prostatic massage urine and serum samples from 148 LUTS patients were analysed using MALDI-TOF/MS. Regression-calibration and simulation and extrapolation methods were used to derive the unbiased association between peptidomic features and PCa. RESULTS: Although the median normalized peptidomic variability was 24.9%, the within- and between-subject variability showed that median normalization, LOD adjustment, and log2 data transformation were the best combination in terms of reliability; in measurement error conditions, intraclass correlation coefficient was a reliable estimate when the LOD/2 was substituted for below LOD values. In the patients studied, 43 peptides were shared by the urine and serum, and several features were found to be associated with PCa. Only few serum features, however, show statistical significance after the multiple testing procedures were completed. Two serum fragmentation patterns corresponded to the complement C4-A. CONCLUSIONS: MALDI-TOF/MS serum peptidome profiling was more efficacious with respect to post-prostatic massage urine analysis in discriminating PCa.

Novel insights on testicular volume and testosterone replacement therapy in Klinefelter patients undergoing testicular sperm extraction. A retrospective clinical study.

STUDY QUESTION: To investigate whether sperm recovery is related to clinical features, hormone parameters and testosterone replacement therapy (TRT) in patients with Klinefelter syndrome (KS). SUMMARY ANSWER: This study provides three interesting insights: (i) the probability to retrieve sperm is not related to testicular volume; (ii) TRT does not affect sperm retrieval rate (SRR); and (iii) reduced levels of LH and FSH represent a negative predictor of sperm retrieval in patients with TRT. WHAT IS KNOWN ALREADY: Classical KS shows a karyotype with one extra X chromosome in all of somatic cells and clinical manifestations characterized by hypergonadotropic hypogonadism and infertility. STUDY DESIGN, SIZE AND DURATION: We performed a retrospective cohort study. Data from 111 consecutive KS azoospermic patients undergoing testicular sperm extraction (TESE) were collected from 2005 to 2016. PARTICIPANTS/MATERIALS, SETTING AND METHODS: Data on anthropometric parameters, reproductive hormones and testicular volumes were collected. SRR was related to clinical characteristics and compared between TRT and untreated patients. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 38 patients (34.2%) had successful sperm recovery. The comparison of clinical characteristics did not differ between patients with and without sperm recovery. Sperm retrieval was successful also in subjects with smaller testes. The comparison of SRR in patients with or without TRT was not different (33.3% vs 34.6%). In TRT group, LH and FSH levels were significantly lower in subjects with no sperm retrieval (P values, respectively, <.05 and <.001). LIMITATIONS AND REASONS FOR CAUTION: Well-designed controlled studies are necessary to confirm these data aimed to set the best therapeutic approach for fertility management in hypogonadal patients with nonmosaic KS. WIDER IMPLICATIONS OF THE FINDINGS: Age at TESE, anthropometric measures, testis volume, sex hormones levels and semen parameters are not predictive parameters of SRR. Among TRT patients, reduced gonadotropin is related to failure in sperm retrieval.

Study of diagnostic accuracy of Fagan's two-step nomogram in increasing the value of predictive tools for prostate cancer: application of specific spatial distribution of positive/negative bioptic cores to predict extracapsular extension.

BACKGROUND: Prostate cancer (PC) represents the second most frequent cancer in the male population worldwide. It is mandatory to have a very accurate staging to choice the best possible treatment. AIMS: To test the possibility of improving the performance of Partin's tables in predicting the pathological staging of PC by introducing bioptic parameters through an innovative statistic tool (Fagan's two-step nomogram). METHODS: We prospectivelly collected data of all 1048 consecutive patients undergoing saturation 24-core transrectal prostate biopsy. Then, in eligible 94 patients, we compared the prediction of presence/absence of extracapsular extension of neoplasm (EPE+/-), with pathological assessment of invasion through (pseudo)capsule in the prostatectomy specimens. Starting from the probability of EPE- (pre-test probability, calculated with formula "100%-risk of EPE+"), we used Fagan's nomogram to examine the diagnostic sensitivity (DSe) and specificity (DSp) of negative "lateral" bioptic cores. RESULTS: We specifically analyzed the status of "lateral" cores in each side (94 patients × 2 sides = 188 sides). "Lateral" cores were negative in 42.5% of sides (80/188) with a DSe and DSp of 91.7 and 45.4%, respectively. In these sides, the mean probability of EPE+ according to Partin's tables was 21.6%. With Fagan's nomogram, the post-test probability of EPE+ when all "lateral" cores were negative was 14.1%, with a substantial gain of 7.5%. DISCUSSION: The spatial distribution of bioptic positive cores allowed us to demonstrate the role Fagan's nomogram in increasing the accuracy of already existing, predictive tools for PC. CONCLUSIONS: This pioneering study may justify the use of the above nomogram in testing "local" predictive parameters in combination with pre-existing nomograms.

Perioperative Outcomes and Early Survival in Octogenarians Who Underwent Radical Cystectomy for Bladder Cancer.

OBJECTIVE: To evaluate perioperative outcomes and early survival in a series of octogenarians who underwent radical cystectomy (RC) and urinary diversion for bladder cancer. PATIENTS AND METHODS: We retrospectively evaluated the clinical records of 44 patients aged ≥80 years who underwent open RC and urinary diversion at 2 high-volume centers between July 2013 and December 2015. Estimated blood loss (EBL), transfusion rate, and length of hospital stay (LOS) were evaluated. Ninety-day postoperative complications were stratified according to the type of urinary diversion. Univariable analysis was performed to identify predictors of overall and major complications. Overall survival (OS) was estimated using the Kaplan-Meier method. RESULTS: Median age was 83 years (interquartile range [IQR] 81-85). Age-adjusted Charlson score was ≥4 in 37 (84%) patients, and American Society of Anesthesiologists score was ≥3 in 34 (77%) patients. Ileal conduit (IC) was performed in 21/44 (48%) cases, cutaneous ureterostomy (CU) in 20/44 (45%), and no urinary diversion was required for 3 (7%) dialytic patients. Median EBL was 700 mL (IQR 500-1,000) and 23 (52%) patients required blood transfusion. Median LOS was 13 days (IQR 10-18). Overall complications were recorded in 29 (66%) patients, with major complications observed in 12 (27%), with death occurring in 1. No differences in complications were observed between IC and CU. The 2-year OS estimate was 62.5%. CONCLUSIONS: Open RC in octogenarians has an acceptable rate of major complications and mortality. IC should be considered a good urinary diversion in these patients.

Pros-IT CNR: an Italian prostate cancer monitoring project.

AIMS: The Pros-IT CNR project aims to monitor a sample of Italian males ≥18 years of age who have been diagnosed in the participating centers with incident prostate cancer, by analyzing their clinical features, treatment protocols and outcome results in relation to quality of life. METHODS: Pros-IT CNR is an observational, prospective, multicenter study. The National Research Council (CNR), Neuroscience Institute, Aging Branch (Padua) is the promoting center. Ninety-seven Italian centers located throughout Italy were involved. The field study began in September 1, 2014. Subjects eligible were diagnosed with biopsy-verified prostate cancer, naïve. A sample size of 1500 patients was contemplated. A baseline assessment including anamnestic data, clinical history, risk factors, the initial diagnosis, cancer staging information and quality of life (Italian UCLA Prostate Cancer Index; SF-12 Scale) was completed. Six months after the initial diagnosis, a second assessment evaluating the patient's health status, the treatment carried out, and the quality of life will be made. A third assessment, evaluating the treatment follow-up and the quality of life, will be made 12 months after the initial diagnosis. The 4th, 5th, 6th and 7th assessments, similar to the third, will be completed 24, 36, 48 and 60 months after the initial diagnosis, respectively, and will include also a Food Frequency Questionnaire and the Physical Activity Scale for the Elderly. DISCUSSION: The study will provide information on patients' quality of life and its variations over time in relation to the treatments received for the prostate cancer.

A circulating miRNA assay as a first-line test for prostate cancer screening.

BACKGROUND: Prostate cancer (PCa) screening currently relies on prostate-specific antigen (PSA) testing and digital rectal examination. However, recent large-scale studies have questioned the long-term efficacy of these tests, and biomarkers that accurately identify PCa are needed. METHODS: We analysed the levels of circulating microRNAs (miRNAs) in patients with elevated PSA who were diagnosed with either localised PCa (n=36) or benign prostatic hyperplasia (BPH, n=31) upon biopsy. Real-time RT-PCR with Taqman probes was used to measure plasma levels of miRNAs. To circumvent problems associated with circulating miRNA quantitation, we computed the expression ratios of upregulated and downregulated miRNAs. RESULTS: The miR-106a/miR-130b and miR-106a/miR-223 ratios were significantly different between the biopsy-positive and BPH groups (P<0.0001), and yielded statistical power values that were >0.99. Both miRNA ratios were highly sensitive and more specific than PSA in discriminating localised PCa from BPH. Receiver operating characteristic curve analysis revealed area under curve values of 0.81 (miR-106a/miR-130b) and 0.77 (miR-106a/miR-223). CONCLUSIONS: Testing for circulating miR-106a/miR-130b and miR-106a/miR-223 ratios may reduce the costs and morbidity of unnecessary biopsies and is feasible for large-scale screening, as it requires measuring only three miRNAs.

Characterization of the Protein Components of Matrix Stones Sheds Light on S100-A8 and S100-A9 Relevance in the Inflammatory Pathogenesis of These Rare Renal Calculi.

PURPOSE: Among the different types of kidney stones, matrix stones are uncommon urinary calculi composed of a soft, pliable, amorphous substance with little crystalline content. To gain insight into the pathogenesis we investigated the protein component by analyzing the proteomic profiles of surgically removed matrix stones. MATERIALS AND METHODS: A total of 5 stones were harvested from 4 patients who underwent surgery for medical reasons at 3 clinical centers during a 7-year period. Matrix stone proteome characterization was performed by mass spectrometry based techniques using an integrated top-down/bottom-up proteomic platform. RESULTS: We identified 142 nonredundant proteins and peptides across all samples. Neutrophil defensin 1, and proteins S100-A8 and S100-A9 were the main components of these renal calculi. CONCLUSIONS: The abundance of identified inflammatory molecules points to an inflammatory process as the event that initializes soft calculi formation rather than as a consequence of such formation. The post-translational oxidative changes in S100-A8 and A9, and the presence of thymosin ß-4, granulins and ubiquitin also suggest the intervention of host defenses through a superimposed, vigorous counter inflammatory process. The post-translational changes seen in the proteins and peptides, and the known self-assembling capability of S100-A8 and S100-A9 probably explain the gelatinous consistency of these stones.

Patterns of prescription and adherence to European Association of Urology guidelines on androgen deprivation therapy in prostate cancer: an Italian multicentre cross-sectional analysis from the Choosing Treatment for Prostate Cancer (CHOICE) study.

OBJECTIVE: To evaluate both the patterns of prescription of androgen deprivation therapy (ADT) in patients with prostate cancer (PCa) and the adherence to European Association of Urology (EAU) guidelines for ADT prescription. METHODS: The Choosing Treatment for Prostate Cancer (CHOICE) study was an Italian multicentre cross-sectional study conducted between December 2010 and January 2012. A total of 1 386 patients, treated with ADT for PCa (first prescription or renewal of ADT), were selected. With regard to the EAU guidelines on ADT, the cohort was categorized into discordant ADT (Group A) and concordant ADT (Group B). RESULTS: The final cohort included 1 075 patients with a geographical distribution including North Italy (n = 627, 58.3%), Central Italy (n = 233, 21.7%) and South Italy (n = 215, 20.0%). In the category of patients treated with primary ADT, a total of 125 patients (56.3%) were classified as low risk according to D'Amico classification. With regard to the EAU guidelines, 285 (26.51%) and 790 patients (73.49%) were classified as discordant (Group A) and concordant (Group B), respectively. In Group A, patients were more likely to receive primary ADT (57.5%, 164/285 patients) than radical prostatectomy (RP; 30.9%, 88/285 patients), radiation therapy (RT; 6.7%, 19/285 patients) or RP + RT (17.7%, 14/285 patients; P < 0.01). Multivariate logistic regression analysis, adjusted for clinical and pathological variables, showed that patients from Central Italy (odds ratio [OR] 2.86; P < 0.05) and South Italy (OR 2.65; P < 0.05) were more likely to receive discordant ADT. CONCLUSION: EAU guideline adherence for ADT was low in Italy and was influenced by geographic area. Healthcare providers and urologists should consider these results in order to quantify the inadequate use of ADT and to set policy strategies to overcome this risk.

Role of dose exposure and inflammatory status in a single center, real-world analysis of sunitinib in patients with metastatic renal cell carcinoma.

UNLABELLED: AIM, PATIENTS & METHODS: To evaluate the real-world setting use of sunitinib, we reviewed data of our patients from January 2007 to December 2014. RESULTS: In 114 patients, sunitinib was used as first-line TKI. Out of 110 evaluable patients, 5 complete responses, 37 partial responses, 42 stabilizations were reported. Median progression-free survival and overall survival (OS) were 14.3 and 28.4 months. Patients who received ≥ 4 full-dose cycles had a better OS (p = 0.02). A neutrophil-lymphocyte ratio <3 was associated both with OS and progression-free survival (50.4 vs 8.4 and 20.0 vs 3.3 months). CONCLUSION: Sunitinib is active and feasible. Patients receiving <4 full-dose cycles or having increased neutrophil-lymphocyte ratio achieved worse outcomes: therefore, these are present potential predictive factors.

Renal colic, where is it headed? An observational study.

AIM: In the last thirty years, the treatment for renal and ureteral calculi has undergone profound variations. The objective of this study has been to evaluate the existence of parameters which can affect the spontaneous expulsion of a symptomatic ureteral stone in a reasonably brief period of time and to identify whether certain parameters such as sex, age, the location and dimension of the stone, the presence of dilation in the urinary tract together with the administered therapy, can be used for a correct clinical management of the patient. METHODS: In a period of 9 months, 486 cases of renal colic were registered at emergency department. RESULTS: The cases of renal colic due to ureteral calculus were 188 (38.7%). The patients' charts, complete of all data and therefore, valid for this research, resulted to be 120 (64%). In the presence of a symptomatic ureteral stone, the correct approach must first of all, focalize on the dimension of the calculus itself; less importance instead, is given to the location, as reported in other studies, the presence of hydroureteronephrosis, sex and the side. CONCLUSION: In the cases when the pain symptoms cannot be solved by means of the administration of analgesics, it is then reasonable to take into consideration an immediate endourological treatment. If the pain symptoms are promptly solved, an attentive wait of 4 weeks should be considered reasonable in order to allow spontaneous expulsion of the calculus.

Recourse to radical prostatectomy and associated short-term outcomes in Italy: a country-wide study over the last decade.

OBJECTIVE: To estimate time trends in the recourse to radical prostatectomy (RP) and associated short-term outcomes after RP in Italy, as population-based data on RP adoption and outcomes are available mainly from Northern America and Northern Europe. PATIENTS AND METHODS: All RPs for prostate cancer performed between 2001 and 2010 were extracted from the Italian national archive of hospital discharge records. Age-specific and age-standardised RP rates were computed. The effect of procedural volume on in-hospital mortality, complications, and length of stay (LOS) was estimated by multilevel regression models. RESULTS: In all, 144,432 RPs were analysed. Country-wide RP rates increased between 2001 and 2004, and thereafter remained stable, with large differences between geographical areas. The mean hospital volume increased in the first study years, without centralisation but due to increasing RP numbers at the population level. The median LOS declined from 10 to 8 days over the study period (mean from 11.7 to 9.2 days). In-hospital mortality declined from 0.16% in 2001 to 0.07% in 2010. In-hospital mortality, LOS, and the prevalence of complications increased with age, and decreased with year of surgery. Compared with very low-volume hospitals, procedures performed in high-volume hospitals were associated with decreased in-hospital mortality, in-hospital complications, and LOS. CONCLUSIONS: The study adds evidence on rapidly changing trends in RP rates in Italy, on improving in-hospital outcomes, and on their association with procedural volume.

Implementing newer agents for the management of castrate-resistant prostate cancer: what is known and what is needed?

Men receiving androgen-deprivation therapy will in time develop metastatic castrate-resistant prostate cancer (mCRPC). Whilst effective treatment options for mCRPC have traditionally been limited, new agents are becoming available. Since 2010, the number and class of agents available to treat mCRPC has increased dramatically. As such, there is a need for clear guidance on the optimum treatment and sequence of treatments for mCRPC before and after chemotherapy. This evidence-based statement, reflecting the views of the authors, provides suggestions on the continued relevance of conventional approaches to first- and second-line treatment in mCRPC, the potential role of novel treatments, and factors that may influence the choice of hormonal agents and/or chemotherapy.

Histopathological characteristics of microfocal prostate cancer detected during systematic prostate biopsy.

OBJECTIVE: To evaluate the prevalence of adverse pathological features and the percentage of multifocal and/or bilateral disease in a series of patients who underwent radical prostatectomy (RP) for unique, microfocal prostate cancer (miPCa) detected on prostate biopsy in the pre-active surveillance (AS) era. PATIENTS AND METHODS: In this retrospective, multi-institutional study, we analysed the clinical records of 131 consecutive patients who underwent either retropubic or robot-assisted RP for miPCa at two referral centres from January 2000 to December 2011. miPCa was defined as a neoplastic lesion present in ≤10% of core with biopsy Gleason score not applicable or biopsy Gleason score 6. RESULTS: There were 17 (13%) pT3-4 prostate cancers and a single case (0.8%) of pN+ tumour. Moreover, 31 (24.1%) patients had a Gleason score of >6 in the RP specimen. Therefore, unfavourable pathological features (pT3-4/N+ and/or Gleason score >6) were present in 40 (30.5%) patients. The median (interquartile range) prostate-specific antigen (PSA) density was 0.11 (0.09-0.17) and 0.16 (0.11-0.24) ng/mL/mL in patients with favourable and unfavourable pathological characteristics, respectively (P = 0.003). The receiver operating characteristic curve had an area under the curve value of 0.67 (95% confidence interval 0.56-0.77) for PSA density to predict the risk of unfavourable pathological features. CONCLUSION: Patients with miPCa who are candidates for an AS protocol should be adequately informed that in ≈30% of cases the cancer might be locally advanced and/or with a Gleason score of >6. Those unfavourable pathological characteristics could be predicted by the PSA density value. Further studies should investigate the role of a more extensive biopsy sampling to reduce the risk of under-staging and/or under-grading in patients with an initial diagnosis of miPCa.
