RESUMO

PURPOSE: Although targeted biopsies (TBx) are associated with improved disease assessment, concerns have been raised regarding the risk of prostate cancer (PCa) overgrading due to more accurate biopsy core deployment in the index lesion. METHODS: We identified 1672 patients treated with radical prostatectomy (RP) with a positive mpMRI and ISUP ≥ 2 PCa detected via systematic biopsy (SBx) plus TBx. We compared downgrading rates at RP (ISUP 4-5, 3, and 2 at biopsy, to a lower ISUP) for PCa detected via SBx only (group 1), via TBx only (group 2), and eventually for PCa detected with the same ISUP 2-5 at both SBx and TBx (group 3), using multivariable logistic regression models (MVA). RESULTS: Overall, 12 vs 14 vs 6% (n = 176 vs 227 vs 96) downgrading rates were recorded in group 1 vs group 2 vs group 3, respectively (p < 0.001). At MVA, group 2 was more likely to be downgraded (OR 1.26, p = 0.04), as compared to group 1. Conversely, group 3 was less likely to be downgraded at RP (OR 0.42, p < 0.001). CONCLUSIONS: Downgrading rates are highest when PCa is present in TBx only and, especially when the highest grade PCa is diagnosed by TBx cores only. Conversely, downgrading rates are lowest when PCa is identified with the same ISUP through both SBx and TBx. The presence of clinically significant disease at SBx + TBx may indicate a more reliable assessment of the disease at the time of biopsy potentially reducing the risk of downgrading at final pathology.

RESUMO

BACKGROUND: Differences have often been reported in the outcomes of bladder cancer (BC) patients according to gender. OBJECTIVE: This study aims to provide data on patients undergoing radical cystectomy (RC) in a high-volume tertiary urologic center and to assess whether gender discrepancies do exist in terms of surgical options and clinical outcomes. MATERIALS AND METHODS: Consecutive BC patients treated between 2016 and 2020 at a single center (Careggi University Hospital, Florence, Italy) were included in the study. The impact of gender on disease stage at diagnosis, overall survival (OS), and type of surgery was analyzed. RESULTS: The study series comprised 447 patients (85 females and 362 males). At a median follow-up of 28.3 months (IQR: 33.5), OS was 52.6% and cancer-specific survival was 67.6%. Significant differences in OS emerged for age, acute myocardial infarction (AMI), Charlson Comorbidity Index (CCI), pT, and pN. OS rates were higher in patients undergoing robot-assisted surgery and in those receiving open orthotopic neobladder (ONB) (p = 0.0001). No statistically significant differences were found between male and female patients regarding surgical offer in any age group, surgical time, early postoperative complications, pathologic stage, and OS. CONCLUSIONS: After adjustment for pathologic tumor stage and treatment modalities, female and male patients showed similar oncologic outcomes. Further studies should be undertaken to evaluate functional results in women subjected to RC.

RESUMO

INTRODUCTION AND OBJECTIVES: An increasing number of urogenital schistosomiasis (UGS) is being diagnosed in Europe following the unprecedented migratory flux from Sub-Saharan Africa (SSA). This phenomenon represent a challenge for urologists working in a non-endemic area. The aim of this study is to describe the urological management and the surgical procedures of patients with UGS in a tertiary referral centre. PATIENTS: All subjects from SAA diagnosed with UGS from January 2011 to November 2018 were enrolled retrospectively. Detailed data of patients with UGS undergoing to urological procedures were collected and analysed. RESULTS: Thirty patients were diagnosed with UGS, among them 12 (42.8%) were submitted to surgery. The most common surgical procedure was trans urethral resection of bladder (TURB) for suspected lesions persisted after praziquantel treatment performed in 7cases (58%). Other surgical procedure were TURB and concomitant ureteroscopy with laser fragmentation for suspected bladder neoplasm with renal stone, endoscopic lithotripsy and percutaneous nephrolithotomy for bladder and renal stones, laparoscopic nephrectomy for end-stage kidney disease, placement of bilateral nephrostomy for hydroureteronephrosis, explorative testicular surgery for a suspected testicular torsion in one case each. Four patients (33%) were lost at the follow up. CONCLUSION: An increasing number of migrants from SSA diagnosed with UGS has been observed. Some patients required a surgical intervention for suspected neoplastic lesions or end-stage organ damage. It was particularly difficult to perform a regular follow-up in several patients. Further multicentric studies are needed to reach a proper standard in diagnosis, treatment and follow-up of subjects with UGS.

RESUMO

BACKGROUND: In search of novel prognostic biomarkers for clear cell renal carcinoma (ccRCC), we analysed the expression of several proteins related to angiogenesis and hypoxia. METHODS: A monocentric study on 30 consecutive surgical samples from surgically-treated ccRCC patients with a 10-year follow up was performed. The following proteins were analysed by immunohistochemistry: Vascular Endothelial Growth Factor- A (VEGF-A), Platelet-Derived Growth Factor ß Receptor (PDGFRß), VEGF-receptor 1 (Flt1), VEGF-receptor 2 (KDR), Glucose Transporter 1 (GLUT1), Carbonic anhydrase IX (CA-IX) and the hERG1 potassium channel. Data were analysed in conjunction with the clinico-pathological characteristics of the patients and follow up. RESULTS: All the proteins were expressed in the samples, with statistically significant associations of VEGF-A with PDGFRß and Flt1 and hERG1 with CA IX. Notably, hERG1 and CAIX co-immunoprecipitated in primary ccRCC samples and survival analysis showed that the positivity for hERG1 and CA IX had a negative impact on Recurrence Free Survival (RFS) at the univariate analysis. At the multivariate analysis only hERG1 maintained its statistically significant negative impact. CONCLUSIONS: hERG1 expression can be exploited to predict recurrence in surgically-treated ccRCC patients. hERG1 channels form a multiprotein complex with the pH regulator CA IX in primary ccRCC samples their potential use as therapeutic target might be suggested.

RESUMO

Objective: Iatrogenic stenosis is a relatively common complication and it could happen after urological procedures in the entire course of the ureter. The aim of this study is to report the surgical outcomes of 36 consecutive patients (period April 2013-November 2018) submitted to robot-assisted correction of benign stricture with previous urological surgery in a tertiary referral center.Methods: Elective criteria were to have had a benign ureteral stricture development after at least one urological procedure. Patients were classified as failures in the event of post-operative ultrasound demonstrating persistent hydronephrosis with or without symptoms or persistent symptoms with renal scan evidence of obstruction or redo procedures.Results: Eighteen patients (50%) were treated for calculosis, seven (19.4%) patients were submitted to double J ureteral stenting and previous pyeloplasty was performed in 11 (30.5%) patients. Overall median operative time was 160 min (IQR = 120-180). Five (13.8%) complications with three (8.3%) surgical post-operative complications occurred. Length of stay was 6 (IQR = 5-7) days. At last follow-up, ranging between 7-60 months, the overall success rate was 86.1% (31/36): three of them (8.3%) were submitted to retrograde holmium laser endopyelotomy, while two (5.5%) underwent a redo robot-assisted correction.Conclusions: Robot-assisted correction procedures can be done safely with good perioperative outcomes and a high post-operative success rate in a tertiary referral center. Further randomized clinical trials are mandatory to confirm the safety of this procedure.

RESUMO

INTRODUCTION: Stent placement in the distal duodenum can be difficult. We describe a case report of a 94-year-old man with metastatic pancreatic head cancer compressing the third and fourth portions of the duodenum, treated by endoscopic stent placement using a colonoscope. AREAS COVERED: A literature review highlighted two possible procedures for stent placement in the distal duodenum, namely forward-viewing and side-viewing endoscopies. Gastroscopes, duodenoscopes, enteroscopes, and colonoscopes have all been suggested for the purpose. For distal lesions, especially when the duodenal wall is stiffened due to compression or infiltration by neoplastic lesions, a conventional upper endoscope can be too short to reach the narrowed site in "push mode," necessitating the use of a longer endoscope. EXPERT COMMENTARY: A colonoscope can be safely and effectively used to accomplish distal duodenal stent placement.

RESUMO

Infertility occurs in up to 54% of men with bilateral undescended testes. Orchiectomy is considered the best therapeutic approach, especially when cryptorchidism is diagnosed in adulthood, due to a high risk of malignancy. A 33-year-old man was referred with a clinical presentation of empty scrotum and an ultrasonography and magnetic resonance imaging evaluation of intra-abdominal bilateral cryptorchidism. Follicle-stimulating hormone was 23.20 IU/L, luteinising hormone was 14.10 IU/L, total testosterone was 12.1 nmol/L, and 17-beta-oestradiol was 0.16 nmol/L. Semen analysis showed absolute azoospermia. Tumour marker levels were in the normal range. Testicular volume was 4.0 ml for right testis and 4.6 ml for left testis. The patient underwent a laparoscopy bilateral orchiectomy and subsequently a testicular sperm extraction (TESE), in the purpose to finding mature spermatozoa. The biological examination revealed the presence of immature sperm cells, not efficient for a cryopreservation. The histologic analyses show a pattern of Sertoli cell-only syndrome and maturation arrest. TESE might be a good option for patients with absolute azoospermia and cryptorchidism, especially if bilateral. The procedure, performed after orchiectomy, is safe and does not have any impact on patient's health, although it is important to clarify the very low potential of sperm recovery.

RESUMO

INTRODUCTION AND OBJECTIVES: To analyze postoperative complications and to assess for significant predictive factors during partial nephrectomy (PN) using a large multicenter dataset. METHODS: Patients who underwent PN for clinical T1 renal tumors at 19 urological Italian centers (Registry of Conservative Renal Surgery [RECORd] project) were evaluated between 2009 and 2012. Anthropometric data, comorbidities and perioperative outcomes were analyzed. Complications were divided as intra- and postoperative, medical and surgical, as appropriate. The severity of postoperative complications was graded according to the modified Clavien classification system. Patients who experienced intraoperative complications were excluded from the analyses for the potential confounding effect in the evaluation of predicting factors for postoperative complications. RESULTS: Overall, 979 patients were analyzed: open, laparoscopic and robot-assisted (available since 2011) surgical approaches were used in 522 (56.4%), 286 (30.9%) and 117 (12.6%) cases, respectively. Surgical postoperative complications were reported in 121 (13.1%) cases (32 (3.5%) were Clavien 3), medical were reported in 52 (5.6%) cases (3 (0.3%) were Clavien 3). No Clavien 4 complications were reported. At multivariable analysis, ECOG score ≥1 (OR 1.98; p = 0.002), lower preoperative hemoglobin (OR 0.71; p < 0.0001) and open surgical approach (2.91; p = 0.02) were significant predictive factors of overall surgical postoperative complications, ECOG score ≥1 (OR 1.93; p = 0.04) and surgical approach (p = 0.05) were significant predictive factors of Clavien 3 either surgical or medical postoperative complications. CONCLUSIONS: Comorbidities and surgical approach should be considered in preoperative evaluation of patients undergoing PN, as they resulted to play a significant role in the occurrence of postoperative complications.

RESUMO

AIM: To assess the role of simple enucleation (SE) for the treatment of highly complex renal tumors. METHODS: Overall, 96 Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) classification score 10 to 13 renal tumors were treated with SE at our institution. All conventional perioperative variables, surgical, functional and oncological results were gathered in a prospectively maintained database. Survival curves were generated using a Kaplan-Meier method. Univariate analysis assessed the outcome differences. RESULTS: Mean (± 1s.d.) clinical tumor diameter was 4.8 (± 1.6 cm). 70.8% of patients had ≥ cT1b stage. The PADUA score was recorded as 10, 11, 12 and 13 in 57.3%, 29.2%, 11.5%, and 2.1% of tumors respectively. Overall, 76 patients were treated with an open approach and 20 robotically. Mean warm ischemia time (WIT) was 19.2 min, and WIT greater than 25 min occurred in 14.6% of cases. Positive surgical margin (PSM) rate was 3.6% and trifecta was achieved in 64.3% of patients. Postoperative surgical complications occurred in 24% of patients, with 14.6% Clavien-Dindo grade 1-2, 8.3% grade 3, and 1% grade 4. Five-year cancer specific survival (CSS), recurrent free survival (RFS), and overall survival (OS) rates resulted 96.1%, 90.8% and 88.0%, respectively. Overall, 4.2% of patients experienced progressive disease. At follow-up, the mean decrease of eGFR from preoperative value was 13.9 ml/min. This was not significantly correlated with PADUA score (p = 0.69). The surgical approach was neither a predictor of Trifecta outcome, nor of postoperative complications, WIT > 25 min or PSM rate. CONCLUSIONS: SE is an effective treatment for highly-complex renal tumors, with a potential key role to widen the NSS (nephron sparing surgery) indications according to guidelines.

RESUMO

INTRODUCTION: Nephron-sparing surgery (NSS) has become the standard of care for the surgical management of small and clinically localized renal cell carcinoma (RCC). The conservative management of those RCCs is increasing over time. Aim of this study was to report a snapshot of the clinical, perioperative and oncological results after NSS for RCC in Italy. MATERIAL AND METHODS: We evaluated all patients who underwent conservative surgical treatment for renal tumours between January 2009 and December 2012 at 19 urological Italian Centers (RECORd project). Perioperative, radiological and histopathological data were recorded. Surgical eras (2009 vs 2012 and year periods 2009-2010 vs 2011-2012) were compared. RESULTS: Globally, 983 patients were evaluated. More recently, patients undergoing NSS were found to be significantly younger (p = 0.05) than those surgically treated in the first study period, with a significantly higher rate of NSS with relative and imperative indication (p < 0.001). More recently, a higher percentage of procedures for cT1b or cT2 renal tumours was observed (p = 0.02). Utilization rate of open partial nephrectomy (OPN) constantly decreased during years, laparoscopic partial nephrectomy (LPN) remained almost constant while robot-assisted partial nephrectomy (RAPN) increased. The rate of clampless NSS constantly increased over time. The use of at least one haemostatic agent has been significantly more adopted in the most recent surgical era (p < 0.001). CONCLUSIONS: The utilization rate of NSS in Italy is increasing, even in elective and more complex cases. RAPN has been progressively adopted, as well as the intraoperative utilization of haemostatic agents and the rate of clampless procedures.

RESUMO

External beam radiation therapy with conventional fractionation to a total dose of 76-80 Gy represents the most adopted treatment modality for prostate cancer. Dose escalation in this setting has been demonstrated to improve biochemical control with acceptable toxicity using contemporary radiotherapy techniques. Hypofractionated radiotherapy and stereotactic body radiation therapy have gained an increasing interest in recent years and they have the potential to become the standard of care even if long-term data about their efficacy and safety are not well established. Strong radiobiological basis supports the use of high dose for fraction in prostate cancer, due to the demonstrated exceptionally low values of α / ß . Clinical experiences with hypofractionated and stereotactic radiotherapy (with an adequate biologically equivalent dose) demonstrated good tolerance, a PSA control comparable to conventional fractionation, and the advantage of shorter time period of treatment. This paper reviews the radiobiological findings that have led to the increasing use of hypofractionation in the management of prostate cancer and briefly analyzes the clinical experience in this setting.

RESUMO

INTRODUCTION: The aim of our work was to investigate the causal connection between M1 and M2 macrophage phenotypes occurrence and prostate cancer, their correlation with tumor extension (ECE), and biochemical recurrence (BR). PATIENT AND METHODS: Clinical and pathological data were prospectively gathered from 93 patients treated with radical prostatectomy. Correlations of commonly used variables were evaluated with uni- and multivariate analysis. The relationship between M1 and M2 occurrence and BR was also assessed with Kaplan-Meier survival analysis. RESULTS: Above all in 63.4% there was a M2 prevalence. M1 occurred more frequently in OC disease, while M2 was more represented in ECE. At univariate analysis biopsy and pathologic GS and M2 were statistically correlated with ECE. Only pathologic GS and M2 confirmed to be correlated with ECE. According to macrophage density BCR free survival curves presented a statistically significant difference. When we stratified our population for M1 and M2,we did not find any statistical difference among curves. At univariate analysis GS, pTNM, and positive margins resulted to be significant predictors of BCR, while M1 and M2 did not achieve the statistical significance. At multivariate analysis, only GS and pathologic stage were independent predictors of BR. CONCLUSION: In our study patients with higher density of M count were associated with poor prognosis; M2 phenotype was significantly associated with ECE.

RESUMO

OBJECTIVES: To compare simple enucleation (SE) and standard partial nephrectomy (SPN) in terms of surgical results in a multicenter dataset (RECORd Project). MATERIALS AND METHODS: patients treated with nephron sparing surgery (NSS) for clinical T1 renal tumors between January 2009 and January 2011 were evaluated. Overall, 198 patients who underwent SE were retrospectively matched to 198 patients who underwent SPN. The SPN and SE groups were compared regarding intraoperative, early post-operative and pathologic outcome variables. Multivariable analysis was applied to analyze predictors of positive surgical margin (PSM) status. RESULTS: SE was associated with similar WIT (18 vs 17.8 min), lower intraoperative blood loss (177 vs 221 cc, p = 0.02) and shorter operative time (121 vs 147 min; p < 0.0001). Surgical approach (laparoscopic vs. open), tumor size and type of indication (elective/relative vs absolute) were associated with WIT >20 min. The incidence of PSM was significantly lower in patients treated with SE (1.4% vs 6.9%; p = 0.02). At multivariable analysis, PSM was related to the surgical technique, with a 4.7-fold increased risk of PSM for SPN compared to SE. The incidence of overall, medical and surgical complications was similar between SE and SPN. CONCLUSIONS: Type of NSS technique (SE vs SPN) adopted has a negligible impact on WIT and postoperative morbidity but SE seems protective against PSM occurrence.

RESUMO

About 70% of patients with renal cell carcinoma present with localized or locally advanced disease at primary diagnosis. Whereas these patients are potentially curable by surgical treatment alone, a further 20% to 30% of patients are diagnosed with primary metastatic disease. Although over the past years medical treatment for metastatic patients has nearly completely changed from immunotherapy to effective treatment with targeted agents, metastatic disease still represents a disease status which is not curable. Also in patients with metastatic disease, surgical treatment of the primary tumor plays an important role, since local tumor related complications can be avoided or minimized by surgery. Furthermore, also improvement of overall survival has been proven for surgery in metastatic patients when combined with cytokine treatment. Hence, surgical combined with systemic treatment as a multi-modal, adjuvant, and neo-adjuvant treatment is also required in patients with advanced or metastatic disease. A growing number of elderly and comorbid patients are currently diagnosed with small renal masses, which has led to increased attention paid to alternative ablative treatment modalities as well as active surveillance strategies, which are applied in order to avoid unnecessary overtreatment in these patients. Since surgical treatment also might enhance the risk of chronic kidney disease with consecutive cardiac disorders as well as reduced overall survival, ablative techniques and active surveillance are increasingly applied. In this review article we focus on current surgical and none-surgical treatment options for the management of patients with localized, locally advanced, and metastatic renal cell carcinoma.

RESUMO

INTRODUCTION: Standardized methods of reporting complications after radical cystectomy (RC) and urinary diversions (UD) are necessary to evaluate the morbidity associated with this operation to evaluate the modified Clavien classification system (CCS) in grading perioperative complications of RC and UD in a real life cohort of patients with bladder cancer. MATERIALS AND METHODS: A consecutive series of patients treated with RC and UD from April 2011 to March 2012 at 19 centers in Italy was evaluated. Complications were recorded according to the modified CCS. Results were presented as complication rates per grade. Univariate and binary logistic regression analysis were used for statistical analysis. RESULTS AND LIMITATIONS: 467 patients were enrolled. Median age was 70 years (range 35-89). UD consisted in orthotopic neobladder in 112 patients, ileal conduit in 217 patients and cutaneous ureterostomy in 138 patients. 415 complications were observed in 302 patients and were classified as Clavien type I (109 patients) or II (220 patients); Clavien type IIIa (45 patients), IIIb (22 patients); IV (11 patients) and V (8 patients). Patients with cutaneous ureterostomy presented a lower rate (8%) of CCS type ≥IIIa (p = 0.03). A longer operative time was an independent risk factor of CCS ≥III (OR: 1.005; CI: 1.002-1.007 per minute; p = 0.0001). CONCLUSIONS: In our study, RC is associated with a significant morbidity (65%) and a reduced mortality (1.7%) when compared to previous experiences. The modified CCS represents an easily applicable tool to classify the complications of RC and UD in a more objective and detailed way.

RESUMO

Recently it has been demonstrated that ten-eleven-translocation-2 (TET2) gene alterations may represent a crucial event in the pathogenesis of various myeloid malignancies. To date, the loss of TET2 function has been solely ascribed to mutations in the gene coding region. In this study, we report a chronic myeloid leukemia (CML) case showing a TET2 single copy partial deletion associated to a t(4;6;11) rearrangement, appearing during the progression of the disease and responsible for a decreased TET2 gene expression. A putative role for TET2 haploinsufficiency in this patient's CML progression is discussed.

RESUMO

AIMS: To investigate the incidence and long-term effects on kidney function of obstructive and nonobstructive dilatation of the upper urinary tract in patients with ileal neobladder with refluxing ureterointestinal anastomoses. METHODS: We retrospectively analyzed a prospectively derived database of 110 patients with bladder cancer and who were treated with an ileal neobladder between 1996 and 2007 using refluxing end-to-side ureterointestinal anastomoses on a short afferent limb. The mean follow up was 65 months. At every follow up visit the patients had an analysis of serum creatinine, urine culture, abdominal CT or ultrasonography, and, if there was dilatation of the upper urinary tract, 99mTc-DTPA renal scintigraphy was requested. RESULTS: In all, 206 renoureteral units were included in the study. Overall, seven had anastomotic stricture and of those, three were symptomatic and were corrected; while four were asymptomatic and of those, only two, with preserved split GFR, were surgically treated, while the remaining two, with a poor split GFR, were followed up. The last 99mTc-DTPA showed a preserved split GFR in the reimplanted units and further split renal function decrease in untreated units. Nonobstructive dilatation of the upper urinary tract, caused by reflux, was diagnosed in 13 units. The dilatation was bilateral in three patients with recurrent UTIs and urosepsis, and the split GFR was bilaterally reduced at diagnosis with a further reduction at the last 99mTc-DTPA. The remaining seven units with sterile urine, showed a preserved split GFR during follow up. CONCLUSIONS: All strictures, regardless of their severity, should be immediately corrected. Reflux per se does not provoke renal impairment unless recurrent UTIs and urosepsis are present.

RESUMO

Using our prospectively derived database, we identified 17 patients with squamous-cell carcinoma involving the glans penis, who were treated using organ-sparing surgery between March 2003 and January 2008. Of them, two were treated with partial glansectomy with primary glans closure, and 15 underwent total glans amputation and reconstruction of a new glans using a split-thickness skin graft (STSG). These 15 patients represent the subject of our study (mean age 51 years, range 42 to 59 years). Overall, two patients had early partial loss of the graft and of them, one required surgical regrafting. Two late complications occurred, consisting of one meatal stenosis and one postoperative phimosis. At a mean follow-up of 36 months, functional results were extremely satisfactory. All patients maintained their erectile function with good vaginal penetration starting from 3 months after surgery, with a range between 2 and 6 months. Orgasm and ejaculation were preserved in all patients, although reduced glans sensitivity was reported by all patients. No local recurrences were reported.
