- Correlation of a microRNA expression profile and the prognosis of penile cancer: A prospective study using microarray data analysis(2018) FURUYA, Tatiane K.; MURTA, Claudio B.; PONTES JR., Jose; UNO, Miyuki; CARRASCO, Alexis; SICHERO, Laura C.; VILLA, Luisa L.; COELHO, Rafael F.; GUGLIELMETTI, Giuliano B.; CORDEIRO, Mauricio D.; LEITE, Katia R.; SROUGI, Miguel; CHAMMAS, Roger; NAHAS, William C.
- 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.
- 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, MiguelObjective 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.
- A Prospective, Randomized Trial Comparing the Outcomes of Open vs Laparoscopic Partial Nephrectomy(2022) GUGLIELMETTI, Giuliano B.; ANJOS, Gabriel C. dos; SAWCZYN, Guilherme; RODRIGUES, Gilberto; CARDILI, Leonardo; CORDEIRO, Mauri Prime Cio D.; NEVES, Luiz C. O.; PONTES JUNIOR, Jose; FAZOLI, Arnaldo; COELHO, Rafael F.; SROUGI, Miguel; NAHAS, William C.Purpose: Partial nephrectomy is the standard treatment for renal tumors <7 cm, and the trend toward minimally invasive surgery has increased. However, data that could support its use and benefits are still lacking. Materials and Methods: We conducted a prospective, randomized controlled trial comparing surgical, functional and oncologic outcomes in patients undergoing open partial nephrectomy (OPN) or laparoscopic partial nephrectomy (LPN). Randomization was 1:1 to OPN or LPN for the treatment of renal tumors <7 cm. The primary endpoint was surgical complications up to 90 days after surgery. Secondary outcomes were comparison of surgical, oncologic and functional results. Results: We randomized 208 patients between 2012 and 2020 (110 with OPN vs 98 with LPN). Operative data showed no differences in operative time, warm ischemia time, estimated blood loss, transfusions or length of hospital stay. Zero ischemia was more frequent in the OPN (35.4% vs 15.5%, p=0.02). OPN was associated with more abdominal wall complications (31.2% vs 13.1%, p=0.004). Regarding oncologic outcomes, no differences were noted. The LPN group had less kidney function reduction at 3 (-5.2% vs -10%, p=0.04; CI 0.09 to 9.46) and 12 months after surgery (-0.8% vs -6.3%, p=0.02; CI 1.18 to 12.95), and a lower rate of downstaging on the chronic kidney disease classification at 12 months (14.1% vs 32.6%, p=0.006). Conclusions: Surgical and oncologic outcomes of LPN were similar to OPN. Minimally invasive surgery may provide better preservation of kidney function. More studies, especially those involving robotic surgery, are necessary to confirm our findings.
