RESUMEN

OBJECTIVES: To assess upgrading rates in patients on active surveillance (AS) for prostate cancer (PCa) after serial multiparametric magnetic resonance imaging (mpMRI). METHODS: We conducted a retrospective analysis of 558 patients. Five different criteria for mpMRI progression were used: 1) a Prostate Imaging Reporting and Data System (PI-RADS) score increase; 2) a lesion size increase; 3) an extraprostatic extension score increase; 4) overall mpMRI progression; and 5) the number of criteria met for mpMRI progression (0 vs 1 vs 2-3). In addition, two definitions of PCa upgrading were evaluated: 1) International Society of Urological Pathology Grade Group (ISUP GG) ≥2 with >10% of pattern 4 and 2) ISUP GG ≥ 3. Estimated annual percent changes methodology was used to show the temporal trends of mpMRI progression criteria. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of mpMRI progression criteria were also analysed. Multivariable logistic regression models tested PCa upgrading rates. RESULTS: Lower rates over time for all mpMRI progression criteria were observed. The NPV of serial mpMRI scans ranged from 90.5% to 93.5% (ISUP GG≥2 with >10% of pattern 4 PCa upgrading) and from 98% to 99% (ISUP GG≥3 PCa upgrading), depending on the criteria used for mpMRI progression. A prostate-specific antigen density (PSAD) threshold of 0.15 ng/mL/mL was used to substratify those patients who would be able to skip a prostate biopsy. In multivariable logistic regression models assessing PCa upgrading rates, all five mpMRI progression criteria achieved independent predictor status. CONCLUSION: During AS, approximately 27% of patients experience mpMRI progression at first repeat MRI. However, the rates of mpMRI progression decrease over time at subsequent mpMRI scans. Patients with stable mpMRI findings and with PSAD < 0.15 ng/mL/mL could safely skip surveillance biopsies. Conversely, patients who experience mpMRI progression should undergo a prostate biopsy.

RESUMEN

PURPOSE: To describe the perioperative safety, functional and immediate post-operative oncological outcomes of minimally invasive RPLND (miRPLND) for testis cancer. METHODS: We performed a retrospective multi-centre cohort study on testis cancer patients treated with miRPLND from 16 institutions in eight countries. We measured clinician-reported outcomes stratified by indication. We performed logistic regression to identify predictors for maintained postoperative ejaculatory function. RESULTS: Data for 457 men undergoing miRPLND were studied. miRPLND comprised laparoscopic (n = 56) or robotic (n = 401) miRPLND. Indications included pre-chemotherapy in 305 and post-chemotherapy in 152 men. The median retroperitoneal mass size was 32 mm and operative time 270 min. Intraoperative complications occurred in 20 (4%) and postoperative complications in 26 (6%). In multivariable regression, nerve sparing, and template resection improved ejaculatory function significantly (template vs bilateral resection [odds ratio (OR) 19.4, 95% confidence interval (CI) 6.5-75.6], nerve sparing vs non-nerve sparing [OR 5.9, 95% CI 2.3-16.1]). In 91 men treated with primary RPLND, nerve sparing and template resection, normal postoperative ejaculation was reported in 96%. During a median follow-up of 33 months, relapse was detected in 39 (9%) of which one with port site (< 1%), one with peritoneal recurrence and 10 (2%) with retroperitoneum recurrences. CONCLUSION: The low proportion of complications or peritoneal recurrences and high proportion of men with normal postoperative ejaculatory function supports further miRPLND studies.

RESUMEN

OBJECTIVES: To develop a novel nomogram to identify candidates for active surveillance (AS) that combines clinical, biopsy and multiparametric magnetic resonance imaging (mpMRI) findings; and to compare its predictive accuracy to, respectively: (i) Prostate Cancer Research International: Active Surveillance (PRIAS) criteria, (ii) Johns Hopkins (JH) criteria, (iii) European Association of Urology (EAU) low-risk classification, and (iv) EAU low-risk or low-volume with International Society of Urological Pathology (ISUP) Grade Group (GG) 2 classification. PATIENTS AND METHODS: We selected 1837 patients with ISUP GG1 or GG2 prostate cancer (PCa), treated with radical prostatectomy (RP) between 2012 and 2018. The outcome of interest was the presence of unfavourable disease (i.e., clinically significant PCa [csPCa]) at RP, defined as: ISUP GG ≥ 3 and/or pathological T stage (pT) ≥3a and/or pathological N stage (pN) 1. First, logistic regression models including PRIAS, JH, EAU low-risk, and EAU low-risk or low-volume ISUP GG2 binary classifications (not eligible vs eligible) were used. Second, a multivariable logistic regression model including age, prostate-specific antigen density (PSA-D), ISUP GG, and the percentage of positive cores (Model 1) was fitted. Third, Prostate Imaging-Reporting and Data System (PI-RADS) score (Model 2), extracapsular extension (ECE) score (Model 3) and PI-RADS + ECE score (Model 4) were added to Model 1. Only variables associated with higher csPCa rates in Model 4 were retained in the final simplified Model 5. The area under the receiver operating characteristic curve (AUC), calibration plots and decision curve analyses were used. RESULTS: Of the 1837 patients, 775 (42.2%) had csPCa at RP. Overall, 837 (47.5%), 986 (53.7%), 348 (18.9%), and 209 (11.4%) patients were eligible for AS according to, respectively, the EAU low-risk, EAU low-risk or low-volume ISUP GG2, PRIAS, and JH criteria. The proportion of csPCa amongst the EAU low-risk, EAU low-risk or low-volume ISUP GG2, PRIAS and JH candidates was, respectively 28.5%, 29.3%, 25.6% and 17.2%. Model 4 and Model 5 (in which only PSA-D, ISUP GG, PI-RADS and ECE score were retained) had a greater AUC (0.84), compared to the four proposed AS criteria (all P < 0.001). The adoption of a 25% nomogram threshold increased the proportion of AS-eligible patients from 18.9% (PRIAS) and 11.4% (JH) to 44.4%. Moreover, the same 25% nomogram threshold resulted in significantly lower estimated risks of csPCa (11.3%), compared to PRIAS (Δ: -14.3%), JH (Δ: -5.9%), EAU low-risk (Δ: -17.2%), and EAU low-risk or low-volume ISUP GG2 classifications (Δ: -18.0%). CONCLUSION: The novel nomogram combining clinical, biopsy and mpMRI findings was able to increase by ~25% and 35% the absolute frequency of patients suitable for AS, compared to, respectively, the PRIAS or JH criteria. Moreover, this nomogram significantly reduced the estimated frequency of csPCa that would be recommended for AS compared to, respectively, the PRIAS, JH, EAU low-risk, and EAU low-risk or low-volume ISUP GG2 classifications.

RESUMEN

PURPOSE: The body mass index (BMI) may be associated with an increased incidence and aggressiveness of urological cancers. In this study, we aimed to evaluate the impact of the BMI on survival in patients with T1G3 non-muscle-invasive bladder cancer (NMIBC). METHODS: A total of 1155 T1G3 NMIBC patients from 13 academic institutions were retrospectively reviewed and patients administered adjuvant intravesical Bacillus Calmette-Guérin (BCG) immunotherapy with maintenance were included. Multivariable Cox regression analysis was performed to identify factors predictive of recurrence and progression. RESULTS: After re-TURBT, 288 patients (27.53%) showed residual high-grade NMIBC, while 867 (82.89%) were negative. During follow-up, 678 (64.82%) suffered recurrence, and 303 (30%) progression, 150 (14.34%) died of all causes, and 77 (7.36%) died of bladder cancer. At multivariate analysis, tumor size (hazard ratio [HR]:1.3; p = 0.001), and multifocality (HR:1.24; p = 0.004) were significantly associated with recurrence (c-index for the model:55.98). Overweight (HR: 4; p < 0.001) and obesity (HR:5.33 p < 0.001) were significantly associated with an increased risk of recurrence. Addition of the BMI to a model that included standard clinicopathological factors increased the C-index by 9.9. For progression, we found that tumor size (HR:1.63; p < 0.001), multifocality (HR:1.31; p = 0.01) and concomitant CIS (HR: 2.07; p < 0.001) were significant prognostic factors at multivariate analysis (C-index 63.8). Overweight (HR: 2.52; p < 0.001) and obesity (HR: 2.521 p < 0.001) were significantly associated with an increased risk of progression. Addition of the BMI to a model that included standard clinicopathological factors increased the C-index by 1.9. CONCLUSIONS: The BMI could have a relevant role in the clinical management of T1G3 NMIBC, if associated with bladder cancer recurrence and progression. In particular, this anthropometric factor should be taken into account at initial diagnosis and in therapeutic strategy decision making.

RESUMEN

BACKGROUND: Several biochemical and clinical markers have been proposed for selecting patients for active surveillance (AS). However, some of these are expensive and not easily accessible. Moreover, currently about 30% of patients on AS harbor aggressive disease. Hence, there is an urgent need for other tools to accurately identify patients with low-risk prostate cancer (PCa). PATIENTS: We retrospectively reviewed the medical records of 260 patients who underwent radical prostatectomy and were eligible for AS according to the following criteria: clinical stage T2a or less, prostate-specific antigen level < 10 ng/mL, 2 or fewer cores involved with cancer, Gleason score (GS) ≤6 grade, and prostate-specific antigen density < 0.2 ng/mL/cc. METHODS: Univariate and multivariate analyses were performed to evaluate the association of patient and tumor characteristics with reclassification, defined as upstaged (pathological stage >pT2) and upgraded (GS ≥7) disease. A base model (age, prostate-specific antigen, prostate volume, and clinical stage) was compared with models considering neutrophil to lymphocyte ratio (NLR) or platelets to lymphocyte ratio (PLR), monocyte to lymphocyte (MLR), and eosinophil to lymphocyte ratio (ELR). OR and 95% CI were calculated. Finally, a decision curve analysis was performed. RESULTS: Univariate and multivariate analyses showed that NLR, PLR, and ELR upgrading were significantly associated with upgrading (ORs ranging from 2.13 to 4.13), but not with upstaging except for MLR in multivariate analysis, showing a protective effect. CONCLUSION: Our results showed that NLR, PLR, and ELR are predictors of Gleason upgrading. Therefore, these inexpensive and easily available tests might be useful in the assessment of low-risk PCa, when considering patients for AS.

RESUMEN

PURPOSE: To evaluate the oncological and functional outcomes of patients diagnosed with penile cancer undergoing conservative treatment through thulium-yttrium-aluminium-garnet (Tm:YAG) laser ablation. METHODS: Twenty-six patients with a penile lesion underwent ablation with a RevoLix 200 W continuous-wave laser. The procedure was carried out with a pen-like laser hand piece, using a 360 µm laser fiber and 15-20 W of power. Median (IQR) follow-up time was 24 (15-30) months. Recurrence rate and post-operative sexual function were assessed. RESULTS: Median age at surgery was 61 years. Median (inter quartile range) size of the lesions was 15 [10-20] mm. Overall, 11 (47.8%) and 12 (52.2%) at the final pathology presented in situ and invasive squamous cell carcinoma (SCC), respectively. The final pathological stage was pTis, pT1a, pT2, and pT3 in 11 (47.8%), 7 (30.4%), 3 (13.0%), and 2 (8.7%) patients, respectively. Moreover, four (17.4%) patients had a recurrence of which three (13.0%) and one (4.3%) patients developed an invasive or in situ recurrence, respectively. After treatment 6 (26.1%) patients reported a conserved penile sensitivity, while 13 (56.5%) and 4 (17.4%) patients experienced a better or worse sensitivity after ablation, respectively. Post-treatment sexual activity was achieved within the first month after laser ablation in 82.6% of the patients. CONCLUSION: Early stage penile carcinomas can be effectively treated with an organ preservation strategy. Tm:YAG conservative laser treatment is easy, safe and offers good functional outcome, with a minor impact on patient's quality of life.

RESUMEN

BACKGROUND: To evaluate the role of confirmatory multiparametric magnetic resonance imaging (mpMRI) of the prostate at the time of Active Surveillance (AS) enrollment to reduce disease misclassification. MATERIALS: From 2012 to 2016, 383 patients with low-risk disease respecting Prostate Cancer Research International AS criteria underwent confirmatory 1.5-T mpMRI. AS was proposed to patients with Prostate Imaging and Report and Data System (PI-RADS) score ≤3 and no extraprostatic extension (EPE), whereas patients with PI-RADS score ≥4 and/or EPE were treated actively. Kaplan-Meier analyses quantified progression-free survival (PFS) in patients enrolled in the AS program. Logistic regression analyses tested the association between confirmatory mpMRI and clinically significant prostate cancer (csPCa) at radical prostatectomy (RP). Diagnostic performance of mpMRI was calculated in patients submitted to immediate RP. RESULTS: PFS rate was 99, 90 and 86% at 1, 2 and 3 years respectively. At multivariable analysis, PI-RADS 3, PI-RADS 4, PI-RADS 5 and EPE increased the probability of having csPCa at immediate RP (PI-RADS 3 [OR] 1.2, p = 0.26; PI-RADS 4 [OR] 5.1, p = 0.02; PI-RADS 5 [OR] 6.7; p = 0.009; EPE [OR] 11.8, p < 0.001). Confirmatory mpMRI showed sensibility, specificity, positive predictive value and negative predictive value of 85, 55, 68 and 76% respectively. CONCLUSIONS: MpMRI at the time of AS enrollment reduces the misclassification rate of csPCa. We suggest to perform target biopsies in patients with PI-RADS score 3 and 4 lesions.

RESUMEN

OBJECTIVE: To evaluate the efficacy and safety of the Virtue® male sling (Coloplast, Humlebaek, Denmark) in a cohort of patients affected by post-prostatectomy stress urinary incontinence (SUI). METHODS: All 29 consecutive patients treated with a Virtue male sling at our Institution between July 2012 and October 2013 were included in the present prospective, non-randomized study. Patients were evaluated preoperatively and at 1, 3, 6, 12, 24 and 36 months after surgery using a 24-h pad weight test, the International Consultation on Incontinence short-form questionnaire (ICIQ-SF), Urinary Symptom Profile (USP) questionnaire, a bladder diary, uroflowmetry and the Patient Global Impression of Improvement (PGI-I) and Patient Global Impression of Severity questionnaires. RESULTS: The mean patient age was 65.5 years. A total of 72.4% of patients had preoperative mild incontinence (1-2 pads/day), while nine patients used 3-5 pads/day. There were a total of 17 complications, which occurred in 29 patients (58.6%); all were Clavien-Dindo grade I. At 12-month follow-up patients showed a significant improvement in 24-h pad test (128.6 vs 2.5 g), number of pads per day (2 vs 0), ICIQ-SF score (14.3 vs 0.9) and USP score for SUI (4 vs 0), and outcomes remained stable at 36 months. At last follow-up, the median score on the PGI-I questionnaire was 1 (very much better). CONCLUSION: The Virtue male sling is an effective treatment option for low to moderate post-prostatectomy incontinence.

RESUMEN

AIM: To assess the predictive value of metabolomic analysis for the presence of prostate cancer (PCa) at first systematic biopsy. PATIENTS & METHODS: Ninety serum samples from patients with suspicion for PCa were included. Targeted and nontargeted metabolomic analysis was performed. RESULTS: Six metabolites were combined into a predictive score. A cutoff value of 0.528 for the metabolomic score showed a good accuracy for the prediction of PCa at biopsy (Area under the curve (AUC): 0.779; p < 0.001). These results were validated in a subgroup of patients, showing similar accuracy (p = 0.1). For patients with prostate specific antigen (PSA) less than 10 ng/ml, the score showed a Se 80.95%, Sp 64.52% for the detection of PCa at biopsy. CONCLUSION: Metabolomic analysis can predict the outcome of the first systematic biopsy.

RESUMEN

OBJECTIVE: Our first objective was to report our experience on robot-assisted vesico-vaginal fistula (VVF) repair after radical surgery for gynecologic malignancies without omental flap interposition using a da Vinci robotic system. The second objective was to critically review the literature in order to analyze surgical solutions used to avoid repair failure. MATERIALS AND METHODS: Five patients with VVF diagnosed after previous open surgery for gynecologic malignancies referred to our tertiary institutions were selected. After an adequate oncologic follow-up, based on the fistula diameter and conservative management failure, robotic surgery repair was proposed. A bivalve 2-layer suturing technique was carried out without tissue interpositions; omentum was not available secondary to previous surgery including hysterectomy, ovaryectomy, and omentectomy and citoreductive peritoneomectomy. A systematic review of the literature was performed in December 2016 using the PubMed database with the following keywords: robotic, robot-assisted, vesico-vaginal, fistula repair. RESULTS: Median age was 62 years (range 55-71) bearing long-lasting VVF were referred to our divisions. Median fistula diameter was 5 mm (range 3-8 mm). Fistula site was the trigone and identified during cystoscopy near the mid-line, left, and right urether meatus, respectively. The median overall and console operatory time were 250 and 120 min, respectively. Blood loss was insignificant (median 40 mL) and the median length of stay was 7 days without any complication. Ten papers were found fulfilling the mentioned criteria, from which 6 were case reports, single or multiple, accounting for the overall 41 robotic-approach-operated patients. CONCLUSION: The quality of the dissection and suture associated with efficient urine drainage are in our opinion the key elements of the success of our technique, which can be performed even without omentum or other tissue flap or graft interposition.

RESUMEN

OBJECTIVE: To evaluate the prognostic role of multiparametric-MRI (mp-MRI) in patients with clinically localized prostate cancer (PCa) eligible for active surveillance (AS) according to Prostate Cancer Research International: Active Surveillance (PRIAS) criteria. PATIENTS AND METHODS: We analyzed prospectively 73 patients with PCa and PRIAS criteria for low-risk disease. All patients fitted criteria for AS but optioned surgery treatment. The mp-MRI was performed to define the likelihood of malignancy according to the Prostate Imaging Reporting and Data System (PIRADS) score (1-5). Patients were divided in 2 groups: non-visible cancer lesion on MRI (PIRADS 2-3) and visible cancer (PIRADS 4-5). Preoperative clinical data (age, body mass index, prostate specific antigen (PSA) level, positive core biopsy, PSA density (PSAD)) and definitive pathological findings (staging, upgrading, unfavorable disease) were compared between groups. PIRADS score was correlated with pathological data to evaluate the prognostic role of mp-MRI; and preoperative variables and definitive pathology (upgrading, upstaging and unfavorable disease) were also assessed. RESULTS: PSAD (p = 0.04) and pathological stage (p = 0.03) were significantly associated with the presence of visible disease. Visible disease was significantly associated with upstaging (p = 0.03). Correlation between PIRADS 5 and unfavorable disease was statistically significant (p = 0.02). The mp-MRI had adequate sensibility in detecting upstaging (92%), intermediate for upgrading (76%) and unfavorable disease (76%). Negative predictive value was higher for upstaging than for upgrading or unfavorable disease (96 vs. 68% and 64%). Multivariate logistic regression revealed that PIRADS 5 was a significant predictor of upstaging (p = 0.05, OR 16.12) and unfavorable disease (p = 0.01, OR 6.53). CONCLUSION: A visible lesion on mp-MRI strongly predicts significant PCa in patients eligible for AS according to PRIAS criteria, based on upstaging and unfavorable disease. We believe that mp-MRI is an important tool and should be added to clinical selection criteria for AS.

RESUMEN

BACKGROUND: Radical external beam radiotherapy (EBRT) is a standard treatment for prostate cancer patients. Despite this, the rate of intraprostatic relapses after primary EBRT is still not negligible. There is no consensus on the most appropriate management of these patients after EBRT failure. For these patients, local salvage therapy such as radical prostatectomy, cryotherapy, and brachytherapy may be indicated. OBJECTIVE: The objectives of this review were to analyze the eligibility criteria for careful selection of appropriate patients and to evaluate the oncological results and complications for each method. METHODS: A review of the literature was performed to identify studies of local salvage therapy for patients who had failed primary EBRT for localized prostate cancer. RESULTS: Most studies demonstrated that local salvage therapy after EBRT may provide long-term local control in appropriately selected patients, although toxicity is often significant. CONCLUSIONS: Our results suggest that for localized prostate cancer recurrence after EBRT, the selection of a local treatment modality should be made on a patient-by-patient basis. An improvement in selection criteria and an integrated definition of biochemical failure for all salvage methods are required to determine which provides the best oncological outcome and least comorbidity.

RESUMEN

BACKGROUND: Bacterial prostatitis (BP) is a common condition accounting responsible for about 5-10% of all prostatitis cases; chronic bacterial prostatitis (CBP) classified as type II, are less common but is a condition that significantly hampers the quality of life, (QoL) because not only is it a physical condition but also a psychological distress. Commonly patients are treated with antibiotics alone, and in particular fluoroquinolones are suggested by the European Urology guidelines. This approach, although recommended, may not be enough. Thus, a multimodal approach to the prolonged antibiotic therapy may be helpful. METHODS: 210 patients affected by chronic bacterial prostatitis were enrolled in the study. All patients were positive to Meares-Stamey test and symptoms duration was > 3 months. The purpose of the study was to evaluate the efficacy of a long lasting therapy with a fluoroquinolone in association with a nutraceutical supplement (prulifloxacin 600 mg for 21 days and an association of Serenoa repens 320 mg, Lactobacillus Sporogens 200 mg, Arbutin 100 mg for 30 days). Patients were randomized in two groups (A and B) receiving respectively antibiotic alone and an association of antibiotic plus supplement. RESULTS: Biological recurrence at 2 months in Group A was observed in 21 patients (27.6%) and in Group B in 6 patients (7.8%). Uropathogens found at the first follow-up were for the majority Gram - (E. coli and Enterobacter spp.). A statistically significant difference was found at the time of the follow-up between Group A and B in the NIH-CPSI questionnaire score, symptoms evidence and serum PSA. CONCLUSIONS: Broad band, short-lasting antibiotic therapy in association with a nutritional supplement (serenoa repens, lactobacillus sporogens and arbutin) show better control and recurrence rate on patients affected by chronic bacterial prostatitits in comparison with antibiotic treatment alone. TRIAL REGISTRATION: NCT02130713. Date of trial Registration: 30/04/2014.

RESUMEN

OBJECTIVE: To report oncological outcomes after thulium-yttrium-aluminum-garnet (Tm:YAG) laser ablation for penile cancer patients. MATERIALS AND METHODS: We retrospectively analyzed 71 patients with ≤cT1 penile cancer (2013-2022). All patients underwent Tm:YAG ablation with a RevoLix 200W continuous-wave laser. First, Kaplan-Meier plots and multivariable Cox regression models tested local tumor recurrence rates. Second, Kaplan-Meier plots tested progression-free survival (≥T3 and/or N1-3 and/or M1). RESULTS: Median (interquartile range) follow-up time was 38 (22-58) months. Overall, 33 (50.5%) patients experienced local tumor recurrence. Specifically, 19 (29%) vs 9 (14%) vs 5 (7.5%) patients had 1 vs 2 vs 3 recurrences over time. In multivariable Cox regression models, a trend for higher recurrence rates was observed for G3 tumors (hazard ratio:6.1; P = .05), relative to G1. During follow-up, 12 (18.5%) vs 4 (6.0%) vs 2 (3.0%) men were retreated with 1 vs 2 vs 3 Tm:YAG laser ablations. Moreover, 11 (17.0%) and 3 (4.5%) patients underwent glansectomy and partial/total penile amputation. Last, 5 (7.5%) patients experienced disease progression. Specifically, TNM stage at the time of disease progression was: (1) pT3N0; (2) pT2N2; (3) pTxN3; (4) pT1N1 and (5) pT3N3, respectively. CONCLUSION: Tm:YAG laser ablation provides similar oncological results as those observed by other penile-sparing surgery procedures. In consequence, Tm:YAG laser ablation should be considered a valid alternative for treating selected penile cancer patients.

RESUMEN

Prostate cancer (PCA) is the most frequent cancer in men. Exposure to infectious agents has been reported to have a putative role in tumorigenesis. Among the infectious agents, convincing evidence has been accumulated about the human polyomavirus BK (BKV). Tissue fresh specimens, serum, and urine samples were collected from 124 consecutive patients, 56 with PCA and 68 with benign prostatic hyperplasia (BPH). Quantitative PCR assays were used to assess the presence of BKV and JC virus (JCV) genomes. BKV-positive tissue specimens were found in 32.1 and 22.1 % of PCA and BPH patients, respectively; in PCA group the number of positive BKV specimens/patients was significantly higher than in BPH group (3.06 vs. 1.73, p = 0.02). JCV genome was found in the biopsies collected from 28.1 and 24.2 % of PCA and BPH patients, respectively, with no significant difference in the rate of JCV specimens/patients between PCA and BPH groups. Our results support the putative causal association between BKV genome and PCA. Further studies are required to demonstrate the direct pathogenetic role of BKV in the PCA occurrence and progression in order to clear the tempting way of vaccine prophylaxis.

RESUMEN

PURPOSE: To describe a new technique for the right template RPLND able to offer a optimal exposure of surgical field, minimal bowel mobilization, and enabling a more "openlike dissection" technique. METHODS: We used a variant of the aortic lymphadenectomy previously described by Magrina et al. for gynecologic malignancies. The patient is placed in a steep Trendelenburg, supine position and the robot column, at the patient's head. The trocar position is specular to that used for RALP and known for generating no collision between the robotic arms. The node dissection of the right template, including laterocaval and interaortocaval nodes, is carried out like in the "open" split-and-roll technique. RESULTS: The docking time was 15', the console time was 192', the blood loss was irrelevant (50 mL), and the number of retrieved nodes was 19. The exposure of the infrarenal vein region of the operatory field resulted optimal without extensive bowel mobilization. The dissection perfectly mimicked the open procedure. CONCLUSIONS: As the left RPLND template includes only para-aortic lymph nodes, the left full flank position seems adequate. On the contrary, it enables a less good exposure of the more extensive right RPLND template, requiring excellent robotic surgical skills to overpass related deadlocks. On the contrary, our technique allows adequate and safe performance of the robotic. It enables a good view of the retroperitoneal space reducing the need of bowel mobilization to obtain a good exposure of the operatory field. Moreover, the patient's supine position makes the procedure more similar to the open technique.

RESUMEN

Sexual disorders following retroperitoneal pelvic lymph node dissection (RPLND) for testis tumor can affect the quality of life of patients. The aim of the current study was to investigate several different andrological outcomes, which may be influenced by robot-assisted (RA) RPLND. From January 2012 to March 2020, 32 patients underwent RA-RPLND for stage I nonseminomatous testis cancer or postchemotherapy (PC) residual mass. Modified unilateral RPLND nerve-sparing template was always used. Major variables of interest were erectile dysfunction (ED), premature ejaculation (PE), dry ejaculation (DE), or orgasm alteration. Finally, fertility as well as the fecundation process (sexual intercourse or medically assisted procreation [MAP]) was investigated. Ten patients (31.3%) presented an andrological disorder of any type after RA-RPLND. Hypospermia was present in 4 (12.5%) patients, DE (International Index of Erectile Function-5 [IIEF-5] <25) in 3 (9.4%) patients, and ED in 3 (9.4%) patients. No PE or orgasmic alterations were described. Similar median age at surgery, body mass index (BMI), number of nodes removed, scholar status, and preoperative risk factor rates were identified between groups. Of all these 10 patients, 6 (60.0%) were treated at the beginning of our robotic experience (2012-2016). Of all 32 patients, 5 (15.6%) attempted to have a child after RA-RPLND. All of these 5 patients have successfully fathered children, but 2 (40.0%) required a MAP. In conclusion, a nonnegligible number of andrological complications occurred after RA-RPLND, mainly represented by ejaculation disorders, but ED occurrence and overall sexual satisfaction deficit should be definitely considered. No negative impact on fertility was described after RA-RPLND.

RESUMEN

A case of thyroid metastasis of a renal clear cell carcinoma is presented. The fine-needle aspiration cytology pointed out the primary tumor origin. The patient underwent robot-assisted radical nephrectomy and contextual thyroidectomy. During the operative procedure, a neoplastic thrombus extending from the thyroid metastasis and protruding into the internal jugular vein was found. As a result, thrombectomy and ligation of the internal jugular vein were required. In cases of single synchronous thyroid metastases form RCC, radical surgery should be advisable. Robotic approach allows to associate major surgery procedures, as nephrectomy, with radical metastasectomy.

RESUMEN

BACKGROUND: Robot-assisted radical cystectomy (RARC) with intracorporeal neobladder (ICNB) remains a very complicated, technically demanding and time-consuming surgical procedure. In the current study we describe our robot-assisted intracorporeal "Shell" neobladder reconstruction. METHODS: From January 2017 to December 2019, we performed 30 intracorporeal ileal neobladder "Shell" reconstructions. We prospectively collected demographics and clinical and pathological data and retrospectively analysed perioperative, functional and oncological outcomes. RESULTS: No conversion to open surgery or intraoperative blood transfusion was necessary. The median whole operative time was 493 min (IQR 433-530 min), ranging from 514 min (IQR 502-554 min) recorded during the first ten procedures to 470 min (IQR 442-503 min) of the last ten. The median estimated blood loss was 400 mL (IQR 350-700 mL). The median length of stay was 11 days (IQR 10-17). Both early and late complication rates were 46.7%. The high-grade early complication rate accounted for 20%, while the high-grade late complication rate was 30%. The daytime continence rate registered was 73.3%, while night-time continence rate was 60%. CONCLUSIONS: Our results demonstrated "Shell" neobladder reconstruction as a technically feasible procedure, with good functional outcomes in tertiary referral centre. Longer follow-up and larger populations are needed to validate these preliminary results.

RESUMEN

PURPOSE: To report long-term oncological outcomes after penile-sparing surgery (PSS) for superficial (Ta-Tis) or initially invasive (T1) penile cancer patients. METHODS: We retrospectively analysed 85 patients with Ta/Tis/T1cN0cM0 penile cancer (1996-2018). All patients underwent PSS: circumcision, excision or laser ablation. First, Kaplan-Meier plots and multivariable Cox regression models tested tumor recurrence rates (any local/regional/metastatic). Second, Kaplan-Meier plots depicted progression-free survival (≥T2 or N1-3 or M1 disease). RESULTS: Median (IQR) follow-up time was 64 (48-95) months. Overall, 48 (56%) patients experienced tumor recurrence. Median (IQR) time to tumor recurrence was 34 (7-52) months. Higher recurrence rates were observed for Tis (65%) and T1 (64%), compared to Ta (40%), but these differences were not significant on multivariable Cox regression analyses (HR:2.0 with 95% CI [0.9-5.1] and HR:2.2 with 95% CI [0.9-5.9], respectively). Moreover, higher recurrence rates were observed for G2-3 tumors (74%), compared to G1 (57%), but these differences were not significant on multivariable Cox regression analyses (HR:1.6; 95% CI [0.8-3.2]). During follow-up, 15 (17.5%) vs. 18 (21.2%) vs. 10 (11.5%) patients underwent 1 vs. 2 vs. ≥3 PSS. Moreover, 26 (30.6%) and 4 (4.7%) men were treated with glansectomy and partial/total penile amputation due to local progression, tumor size or patient preference. Additionally, 24 (28%) men underwent invasive nodal staging. Last, 22 (25.9%) patients experienced disease progression. Median (IQR) time to disease progression was 51 (31-82) months. CONCLUSION: Patients treated with PSS for newly diagnosed superficial or initially invasive squamous cell carcinoma of the penis should be informed about the non-negligible risk of tumor recurrence and disease progression over time. In consequence, strict follow-up protocols are needed.
