Purpose To evaluate the effect of risk factors and selected surgical methods on operative and oncological results of patients undergoing radical prostatectomy (RP) with high-risk prostate cancer (HRPC). Methods Retrospective analysis of patients, who underwent RP for HRPC from 13 urology centers between 1990 to 2019, was performed. Groups were created according to the risk factors of D’Amico classification. Patients with one risk factor were included in group 1 where group 2 consisted of patients with two or three risk factors. Results A total of 1519 patients were included in this study and 1073 (70.6%) patients assigned to group 1 and 446 (29.4%) patients to group 2. Overall (biochemical and/or clinical and/or radiological) progression rate was 12.4% in group 1 and 26.5% in group 2 (p =0.001). Surgical procedure was open RP in 844 (55.6%) patients and minimally invasive RP in 675 (44.4%) patients (laparoscopic and robot-assisted RP in 230 (15.1%) and 445 (29.3%) patients, respectively). Progression rates were similar in different types of operations (p=0.22). Progression rate was not significantly different in patients who either underwent pelvic lymph node dissection (PLND) or not in each respective group. Conclusion RP alone is an effective treatment in the majority of patients with HRPC and PLND did not affect the progression rates after RP. According to the number of preoperative high-risk features, as the number of risk factors increases, there is a need for additional treatment.

Abstract Purpose: To compare the functional outcomes of patients who underwent partial (PN) or radical nephrectomy (RN) for clinical T1 (cT1) renal tumors using the Kidney Cancer Database of the Urooncology Association, Turkey. Methods: We retrospectively reviewed 1004 patients who underwent PN and RN for cT1 renal tumors at multiple academic tertiary centers between 2000 and 2018. Patients with preoperative end-stage chronic kidney disease and/or metastatic disease were excluded. Results: There were 452 patients in the PN group and 552 patients in the RN group. The eGFR was significantly reduced in both groups on postoperative day one (PN=13.7 vs. RN=19.1 ml/min/1.73 m2: p<0.001). In the PN group, eGFR showed a tendency to recover according to a quadratic pattern and reached preoperative levels in the first and third years (95.6±28.8 ml/min/1.73 m2 and 96.9±28.9 ml/min/1.73 m2, respectively), with no significant difference between the eGFRs in the 1st and 3rd years (p=0.710). To define groups at risk, different cut-off values for the GFR were considered. Among patients with a baseline GFR<90, the RN cohort had significantly lower eGFRs in the first and third years than the PN cohort (p=0.02). Logistic regression showed that comorbidities, coronary artery disease, diabetes and hypertension had no adverse impacts on the changes in the eGFR (p=0.60, p=0.13, and p=0.13, respectively). Conclusion: For the treatment of stage T1 kidney tumors, the first choice should be open or laparoscopic partial nephrectomy due to the superior long-term preservation of renal function and overall survival, regardless of age and comorbidities.

Objective: We aimed to evaluate the effect of body mass index (BMI) on oncological and surgical outcomes in patients who underwent radical cystectomy (RC) for bladder cancer (BC). Materials and Methods We retrospectively assessed data from patients who underwent RC with pelvic lymphadenectomy and urinary diversion for BC recorded in the bladder cancer database of the Urooncology Association, Turkey between 2007 and 2019. Patients were stratified into three groups according to the BMI cut-off values recommended by the WHO; Group 1 (normal weight, <25 kg/m2), Group 2 (overweight, 25.0–29.9 kg/m2) and Group 3 (obese, ≥30 kg/m2) Results In all, 494 patients were included, of them 429 (86.8%) were male and 65 (13.2%) were female. The median follow-up was 24 months (12-132 months). At the time of surgery, the number of patients in groups 1, 2 and 3 were 202 (40.9%), 215 (43.5%) and 77 (15.6%), respectively. The mean operation time and time to postoperative oral feeding were longer and major complications were statistically higher in Group 3 compared to Groups 1 and 2 (p=0.019, p<0.001 and p=0.025 respectively). Although the mean overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS) and metastasis-free survival (MFS) was shorter in cases with BMI ≥30 kg/m2 compared with other BMI groups, differences were not statistically significant (p=0.532, p=0.309, p=0.751 and p=0.213 respectively). Conclusion Our study showed that, although major complications are more common in obese patients, the increase in BMI does not reveal a significant negative effect on OS, CSS, RFS, and MFS.
