- Robotic-assisted approaches to urachal carcinoma: A comprehensive systematic review of the safety and efficacy outcomes(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 AlvesIntroduction 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.
- Scoring system for prediction of overall survival in patients with renal cell carcinoma T3aN0M0(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 CarlosObjectiveWe 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.
- Tumor mutational burden (TMB) and BCG responsiveness in high-risk non-muscle invasive bladder cancer (NMIBC).(2019) BASTOS, Diogo Assed; LIMA, Mariana; MATTEDI, Romulo Loss; SANTOS, Filipe Ferreira dos; BUZATTO, Vanessa; BARREIRO, Rodrigo; RIBEIRO-FILHO, Leopoldo; CORDEIRO, Mauricio; AMANO, Mariane; SOUZA, Jussara Michaloski; BETTONI, Fabiana; GALANTE, Pedro Alexandre Favoretto; DZIK, Carlos; NAHAS, William Carlos; CAMARGO, Anamaria Aranha
- 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 CarlosObjective: 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.

conferenceObject Randomized phase II trial of neoadjuvant androgen deprivation therapy plus abiraterone and apalutamide for patients with high-risk localized prostate cancer: Pathologic response and PSMA imaging correlates.(2022) BASTOS, Diogo Assed; COELHO, Rafael; CARDILI, Leonardo; GALIZA, Felipe; ILARIO, Eder Nisi; VIANA, Ublio; MURTA, Claudio Bovolenta; GUGLIELMETTI, Giuliano; CORDEIRO, Mauricio; PONTES JR., Jose; MUNIZ, David Queiroz Borges; SILVA, Jamile Almeida; MOTA, Jose Mauricio; FREITAS, Guilherme Fialho De; LEITE, Katia Ramos Moreira; BUCHPIGUEL, Carlos Alberto; NAHAS, William Carlos- Neutrophil-to-Lymphocyte Ratio Predicts Cancer Outcome in Locally Advanced Clear Renal Cell Carcinoma(2022) CORDEIRO, Mauricio Dener; ILARIO, Eder Nisi; ABE, Daniel Kanda; CARVALHO, Paulo Afonso de; MUNIZ, David Queiroz Borges; SARKIS, Alvaro Sadek; COELHO, Rafael Ferreira; GUIMARAES, Ronaldo Morales; HADDAD, Michel Vitor; NAHAS, William CarlosBackground: To evaluate the association of neutrophil-to-lymphocyte ratio (NLR) with recurrence-free survival (RFS) and overall survival (OS) in patients with locally advanced nonmetastatic clear cell renal cell carcinoma (ccRCC) under-going radical nephrectomy. Material and Methods: We retrospectively identified 880 nephrectomies performed between January 2009 and December 2016 in a single center, reviewed data from 478 radical nephrectomies for kidney tumors and identified 187 patients with locally advanced nonmetastatic ccRCC (pT3-T4 N0M0). NLR was obtained preoperatively and calculated by dividing absolute neutrophil count by absolute lymphocyte count. OS and RFS were evaluated by the Kaplan-Meier method. Cox proportional-hazards regression models were used to evaluate predictors of RFS and OS. Results: Among 187 patients with ccRCC (mean age 63.4 +/- 11.5 years; 118 [63.1%] male), the median follow-up was 48.7 months. On univariate analysis, in patients with Fuhrman nuclear grade of differentiation 3-4, the median time to recurrence was significantly shorter with NLR >= 4 than < 4 (24 vs. 55 months, P = .045). On multivariable analysis adjusted for NLR >= 4, among all variables analyzed (NLR, microvascular invasion, sarcomatoid differentiation, tumor size and body mass index), only nuclear grade of differentiation was an independent predictor of recurrence (hazard ratio 2.18; 95% confidence interval 1.07-4.92, P = .03). The 3-year OS had no statistically significant difference between patients with NLR >= 4 or < 4. Conclusion: For patients with locally advanced, nonmetastatic ccRCC, RFS was reduced with high nuclear grade of differentiation and high preoperative NLR. These findings suggest an association between higher NLR and worse outcomes in locally advanced ccRCC.
- Robotic-assisted radical cystectomy: the first multicentric Brazilian experience(2020) MOSCHOVAS, Marcio Covas; CHADE, Daher Cesar; ARAP, Marco Antonio; SARKIS, Alvaro Sadek; NAHAS, William Carlos; TANURE, Luiz Henrique Rodrigues; EBAID, Gustavo; FAZOLI, Arnaldo Jose de Carvalho; GUGLIELMETTI, Giuliano Betoni; BISTACCO, Carolina; CORDEIRO, Mauricio; AFONSO, Paulo; SIGHINOLFI, Maria Chiara; ROCCO, Bernardo; COELHO, Rafael FerreiraThe objective of this study is to report the first multicentric Brazilian series and learning curve of robotic radical cystectomy (RARC) with related intra- and postoperative outcomes. We retrospectively analyzed 37 RARC prospectively collected at four different centers in Brazil, from 2013 to 2019. We analyzed the patient's demographics, pathological tumor, and nodal status, as well as intra- and postoperative outcomes. Statistical analysis was performed with the IBM (SPSS version 25) software. Overall, 86% were male, and the median age was 69 years. 83% had muscle-invasive bladder cancer, and 17% a high-grade, recurrent non-muscle-invasive tumor. The median operative time was 420 min with 300 min as console time. Median blood loss was 350 ml and transfusion rate was 10%. In 68% of the cases, we performed an intracorporeal Bricker urinary diversion, 24% intracorporeal neobladder, and 8% ureterostomy. Six patients (16%) had a Clavien 1-2, 8% had Clavien 3, 2.5% had a Clavien 4, and 5% had Clavien 5. The median length of hospital stay was 7 days. The final pathological exam pointed out pT0 in 16%, pT1 in 8%, pT2 in 32%, >= pT3 in 27%, and 16% pTis. 95% had negative surgical margins. The survival at 30, 90, and 180 days was 98%, 95%, and 95%, respectively. To our knowledge, this is the first multicentric series of RARC reporting the learning curve in Brazil; even if still representing a challenging procedure, RARC could be safely and effectively faced by experienced surgeons at centers with high volumes of robotic surgery.
