Background: In patients with renal cell carcinoma (RCC) the role of the extent of tumor thrombus into the inferior vena cava (IVC) has never been addressed from a surgical and oncologic standpoint. This study aims to evaluate differences between level III–IV versus level I–II patients concerning peri- and postoperative morbidity, additional treatments and long-term oncological outcomes. Patients and Methods: Overall, 40 patients with RCC underwent radical nephrectomy (RN) with IVC thrombectomy at a single European institution between 2010 and 2023. Complications were reported according to the European Union (EAU) guidelines recommendations. Spider chart served as graphical depiction of surgical and oncologic outcomes. Results: Overall, 22 (55%) and 18 (45%) patients harbored level III–IV and I–II IVC thrombus. Level III–IV patients experienced significantly higher rates of intraoperative transfusions (68 vs 39%), but not significantly higher rates of intraoperative complications (32% vs 28%). Level III–IV patients had significantly higher rates of postoperative transfusions (82% vs 33%) and Clavien Dindo ≥3 complications (41% vs 15%). In level III–IV versus level I–II patients, median follow up was 482 and 1070 days, the rate of distant recurrence was 59% and 50%, the rate of systemic progression was 27% and 13%, and the rate of additional treatment/s was 64% and 61%, respectively (all p values > 0.05). Overall survival was 36% in level III–IV patients and 67% in level I–II (p = 0.001). Conclusions: Our findings suggest that patients with level III–IV RCC who are candidates for IVC thrombectomy should be counselled about the higher likelihood of postoperative severe adverse events and worse overall survival relative to level I–II counterparts.

Background: It is unknown whether perioperative and functional outcomes of Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) may be affected by large prostate sizes (PS). Methods: All patients treated with RS-RARP were identified and compared according to PS. The definition of PS relied on the prostatic weight at final pathology (PS < 100 g vs ≥ 100 g). Multivariable logistic regression models tested immediate and 12-month urinary continence recovery (UCR, namely, 0–1 safety pad per-day), and positive surgical margins (PSM). Multivariable Poisson log-linear regression analyses tested operative time (OT), estimated blood loss (EBL), and length of stay (LOS). The analyses relied on the database of a high-volume European institution (2010–2022). Results: Of 1,555 overall patients, 1503 (96.7%) had a PS < 100 g and 52 (3.3%) had a PS ≥ 100 g. No differences were recorded in LOS (3 days), and intraoperative (1.9 vs 2.3%) as well as postoperative complications (13 vs 12%; all p values > 0.05). No significant difference was recorded in PSM (25 vs 23%, p = 0.6). In patients with PS ≥ 100 g vs < 100 g, immediate UCR rate was 42 vs 64% (p = 0.002), and 12-month UCR rate was 87 vs 88% (p = 0.3). PV ≥ 100 g independently predicted worse immediate UCR (odds ratio 0.55, 95% CI 0.30–0.98, p = 0.044), but not worse 12-month UCR (p = 0.3) or higher PSM (p = 0.7). PV ≥ 100 g independently predicted longer OT (incidence rate ratio [IRR] 1.12, 95% CI 1.10–1.15, p < 0.001) and higher EBL (IRR 1.26, 95% CI 1.24–1.28, p < 0.001), but not longer LOS (p = 0.3). Conclusions: RS-RARP is a valid option for prostate cancer treatment, even in case of very large prostates. Specifically, no significant association was recognized between PS ≥ 100 g and PSM or 12-month UCR. [ABSTRACT FROM AUTHOR]
