    (2024) SUARTZ, Caio Vinicius; MARTINEZ, Lucas Motta; BRITO, Pedro Henrique; NETO, Carlos Victori; CORDEIRO, Mauricio Dener; BOTELHO, Luiz Antonio Assan; GALLUCCI, Fabio Pescarmona; MOTA, Jose Mauricio; NAHAS, William Carlos; RIBEIRO-FILHO, Leopoldo Alves
    Introduction Surgical intervention is the treatment of choice in patients with urachal carcinoma. Due to complications and to reduce hospital stay from open surgery, minimally invasive approaches are desirable. Nowadays, robotic-assisted surgery has become increasingly popular, and robot-assisted cystectomy can be performed in patients with urachal carcinoma with low complication rates. Methods We performed a systematic review to search for studies that evaluated patients who underwent robotic-assisted surgery for urachal carcinoma. The outcomes of interest were the type of cystectomy performed, whether there was umbilicus resection, total operative time, console time, intraoperative complications, estimated blood loss, postoperative complications, time of hospitalisation, positive surgical margins and the presence of documented tumour recurrence. Results In this study, we evaluated three cohorts comprising a total of 21 patients. The median follow-up period ranged from 8 to 40 months. Medium age was between 51 and 54 years, with a majority (63.1%) being male. One patient (5.2%) underwent a radical cystectomy, and 19 patients (94.7%) underwent to partial cystectomy. Umbilical resections were performed in all cases, and pelvic lymphadenectomy in 14 cases (73.6%). Recurrence occurred in three patients at a median of 17 months postoperation, two cases in the trocar insertion site. Additionally, there was one death, which was attributed to postoperative cardiovascular complications. Conclusion Robotic-assisted partial cystectomy has a low incidence of adverse outcomes in patients with urachal carcinoma. Controlled studies, ideally randomised, are warranted to establish the comparative efficacy and safety of the robotic-assisted cystectomy approach relative to open surgery.

    (2024) SUARTZ, Caio Vinicius; CORDEIRO, Mauricio Dener; CARVALHO, Paulo Afonso de; GALLUCCI, Fabio Pescarmona; RIBEIRO-FILHO, Leopoldo Alves; CARDILI, Leonardo; SIVARAMAN, Arjun; AUDENET, Francois; MOTA, Jose Mauricio; NAHAS, William Carlos
    ObjectiveWe aim to create a new score to predict postoperative overall survival in patients with nonmetastatic T3aN0 renal cell carcinoma.MethodsWe reviewed the clinical data of adult patients who underwent radical nephrectomy for renal cell carcinoma between December 2007 and January 2022 in a single tertiary oncological institution. Clinical characteristics, clinical-pathological staging and histopathological characteristics were analysed. Survival analyses were determined using the Kaplan-Meier curve. A nomogram was established using Cox proportional hazard regression to identify the prognostic factors affecting the overall survival. The area under the curve, calibration curves and decision curve analysis were used to evaluate prognostic efficacy.ResultsWe analyzed 362 patients classified as pT3aN0M0 stage with a median follow-up of 40 months. According to Cox univariate and multivariate analyses, weight loss greater than 5% in 6 months before surgery, stage V chronic kidney disease after radical nephrectomy, sarcomatoid pattern, and coagulative tumor necrosis were identified as predictors of overall survival. We developed a score and performed internal and external validation. The time-dependent receiver operating characteristic curve, area under the curve value and calibration curve analysis showed good prediction ability of the score. The nomogram can effectively predict and stratify overall survival after radical nephrectomy in patients with pT3aN0M0 renal cell carcinoma.ConclusionPatients with pT3aN0MO renal cell carcinoma exhibited different characteristics, and those with unfavourable characteristics deserve greater attention during follow-up. This nomogram provides an accurate prediction of overall survival after radical nephrectomy.

    Value of 3-Tesla multiparametric magnetic resonance imaging and targeted biopsy for improved risk stratification in patients considered for active surveillance
    (2017) PESSOA, Rodrigo R.; VIANA, Publio C.; MATTEDI, Romulo L.; GUGLIELMETTI, Giuliano B.; CORDEIRO, Mauricio D.; COELHO, Rafael F.; NAHAS, William C.; SROUGI, Miguel
    Objective To evaluate the role of multiparametric magnetic resonance imaging (mpMRI) of the prostate and transrectal ultrasonography guided biopsy (TRUS-Bx) with visual estimation in early risk stratification of patients with prostate cancer on active surveillance (AS). Patients and Methods Patients with low-risk, low-grade, localised prostate cancer were prospectively enrolled and submitted to a 3-T 16-channel cardiac surface coil mpMRI of the prostate and confirmatory biopsy (CBx), which included a standard biopsy (SBx) and visual estimation-guided TRUS-Bx. Cancersuspicious regions were defined using Prostate Imaging Reporting and Data System (PI-RADS) scores. Reclassification occurred if CBx confirmed the presence of a Gleason score >= 7, greater than three positive fragments, or >= 50% involvement of any core. The performance of mpMRI for the prediction of CBx results was assessed. Univariate and multivariate logistic regressions were performed to study relationships between age, prostate-specific antigen (PSA) level, PSA density (PSAD), number of positive cores in the initial biopsy, and mpMRI grade on CBx reclassification. Our report is consistent with the Standards of Reporting for MRItargeted Biopsy Studies (START) guidelines. Results In all, 105 patients were available for analysis in the study. From this cohort, 42 (40%) had PI-RADS 1, 2, or 3 lesions and 63 (60%) had only grade 4 or 5 lesions. Overall, 87 patients underwent visual estimation TRUS-Bx. Reclassification among patients with PI-RADS 1, 2, 3, 4, and 5 was 0%, 23.1%, 9.1%, 74.5%, and 100%, respectively. Overall, mpMRI sensitivity, specificity, positive predictive value, and negative predictive value for disease reclassification were 92.5%, 76%, 81%, and 90.5%, respectively. In the multivariate analysis, only PSAD and mpMRI remained significant for reclassification (P < 0.05). In the crosstabulation, SBx would have missed 15 significant cases detected by targeted biopsy, but SBx did detect five cases of significant cancer not detected by targeted biopsy alone. Conclusion Multiparametric magnetic resonance imaging is a significant tool for predicting cancer severity reclassification on CBx among AS candidates. The reclassification rate on CBx is particularly high in the group of patients who have PI-RADS grades 4 or 5 lesions. Despite the usefulness of visual-guided biopsy, it still remains highly recommended to retrieve standard fragments during CBx in order to avoid missing significant tumours.

    Histological Variants of Urothelial Carcinoma Predict No Response to Neoadjuvant Chemotherapy
    (2022) LEITE, Katia Ramos Moreira; BORGES, Leonardo Lima; RIBEIRO FILHO, Leopoldo; CHADE, Daher; COELHO, Rafael Ferreira; CORDEIRO, Mauricio; SROUGI, Miguel; NAHAS, Willian Carlos
    Microabstract: This study shows that the presence of divergent histological differentiation and the immunexpression of CAIX in muscle invasive urothelial carcinoma, predicts no response to cisplatin based neoadjuvant chemotherapy. Background: Platinum-based neoadjuvant chemotherapy (NAC) in muscle-invasive urothelial bladder cancer (MIBC) has been adopted as a standard of care related to better survival outcomes. However, there is a considerable number of patients who do not respond, experiencing toxicity and delay in the surgical treatment. Our aim is to find biomarkers of response that could be easily adopted in the clinical practice. Methods: Between January 2009 and July 2016, 52 patients with MIBC were submitted to radical cystectomy after NAC. A tissue microarray containing 25 cases, who met the inclusion criteria was built for immunohistochemical analysis of Cytokeratins 5/6, 7, and 20, GATA3, Her2, EGFR, p63, p53, Carbonic-anhydrase IX (CAIX), MLH1, MSH2, MSH6, and PMS2. The surgery was performed in a mean time of 58.7 (+/- 21) days after the end of the NAC. Fisher's exact test was used to analyze the relationship between response (<= pT1) and histopathological and immunohistochemical results and Kaplan-Meier curves were designed for survival analysis. Results: Ten (40.0%) patients presented response to NAC. Histological variants of the urothelial carcinoma characterized by squamous, sarcomatous/rhabdoid, plasmacytoid, and micropapillary was present in 36.0% and none responded to NAC (P = .002). CAIX was expressed by 53.3% and none responded to NAC (P= .005). Lymph-node metastasis, divergent differentiation, and expression of cytokeratin 5/6 were related to short cancer specific survival. Conclusion: Histological variants and CAIX immune-expression are biomarkers of nonresponse to NAC of MIBC, and might be easily used in the clinical practice to select patients to be submitted to surgery upfront.

    Predictive factors for prolonged hospital stay after retropublic radical prostatectomy in a high-volume teaching center
    (2018) COELHO, Rafael F.; CORDEIRO, Mauricio D.; PADOVANI, Guilherme P.; LOCALLI, Rafael; FONSECA, Limirio; PONTES JUNIOR, Jose; GUGLIELMETTI, Giuliano B.; SROUGI, Miguel; NAHAS, William Carlos
    Objective: To evaluate the length hospital stay and predictors of prolonged hospitalization after RRP performed in a high-surgical volume teaching institution, and analyze the rate of unplanned visits to the office, emergency care, hospital readmissions and perioperative complications rates. Materials and Methods: Retrospective analysis of prospectively collected data in a standardized database for patients with localized prostate cancer undergoing RRP in our institution between January/2010 - January/2012. A logistic regression model including preoperative variables was initially built in order to determine the factors that predict prolonged hospital stay before the surgical procedure; subsequently, a second model including both pre and intraoperative variables was analyzed. Results: 1011 patients underwent RRP at our institution were evaluated. The median hospital stay was 2 days, and 217 (21.5%) patients had prolonged hospitalization. Predictors of prolonged hospital stay among the preoperative variables were ICC (OR. 1.40 p=0.003), age (OR 1.050 p<0.001), ASA score of 3 (OR. 3.260 p<0.001), prostate volume on USG-TR (OR, 1.005 p=0.038) and African-American race (OR 2.235 p=0.004); among intra and postoperative factors, operative time (OR 1.007 p=0.022) and the presence of any complications (OR 2.013 p=0.009) or major complications (OR 2.357 p=0.01) were also correlated independently with prolonged hospital stay. The complication rate was 14.5%. Conclusions: The independent predictors of prolonged hospitalization among preoperative variables were CCI, age, ASA score of 3, prostate volume on USG-TR and African-American race; amongst intra and postoperative factors, operative time, presence of any complications and major complications were correlated independently with prolonged hospital stay.

    A prognostic model for survival after palliative urinary diversion for malignant ureteric obstruction: a prospective study of 208 patients
    (2016) CORDEIRO, Maurcio D.; COELHO, Rafael F.; CHADE, Daher C.; PESSOA, Rodrigo R.; CHAIB, Mateus S.; COLOMBO-JUNIOR, Jose R.; PONTES-JUNIOR, Jose; GUGLIELMETTI, Giuliano B.; SROUGI, Miguel
    Objective To identify factors associated with survival after palliative urinary diversion (UD) for patients with malignant ureteric obstruction (MUO) and create a risk-stratification model for treatment decisions. Patients and Methods We prospectively collected clinical and laboratory data for patients who underwent palliative UD by ureteric stenting or percutaneous nephrostomy (PCN) between 1 January 2009 and 1 November 2011 in two tertiary care university hospitals, with a minimum 6-month follow-up. Inclusion criteria were age >18 years and MUO confirmed by computed tomography, ultrasonography or magnetic resonance imaging. Factors related to poor prognosis were identified by Cox univariable and multivariable regression analyses, and a risk stratification model was created by Kaplan-Meier survival estimates at 1, 6 and 12 months, and log-rank tests. Results The median (range) survival was 144 (0-1084) days for the 208 patients included after UD (58 ureteric stenting, 150 PCN); 164 patients died, 44 (21.2%) during hospitalisation. Overall survival did not differ by UD type (P = 0.216). The number of events related to malignancy (>= 4) and Eastern Cooperative Oncology Group (ECOG) index (> 2) were associated with short survival on multivariable analysis. These two risk factors were used to divide patients into three groups by survival type: favourable (no factors), intermediate (one factor) and unfavourable (two factors). The median survival at 1, 6, and 12 months was 94.4%, 57.3% and 44.9% in the favourable group; 78.0%, 36.3%, and 15.5% in the intermediate group; and 46.4%, 14.3%, and 7.1% in the unfavourable group (P < 0.001). Conclusions Our stratification model may be useful to determine whether UD is indicated for patients with MUO.
