While partial nephrectomy (PN) represents the standard surgical management for cT1 renal masses, its role for cT2 tumors is controversial. Robot-assisted PN (RAPN) is being increasingly implemented worldwide. To analyze perioperative, functional, and oncological outcomes of RAPN for cT2 tumors. Retrospective analysis of a large multicenter, multinational dataset of patients with nonmetastatic cT2 masses treated with robotic surgery (ROSULA: RObotic SUrgery for LArge renal mass). Robotic-assisted PN. Patients' demographics, lesion characteristics, perioperative variables, renal functional data, pathology, and oncological data were analyzed. Univariable and multivariable regression analyses assessed the relationships with the risk of intra-/postoperative complications, recurrence, and survival. A total of 298 patients were analyzed. Median tumor size was 7.6 (7-8.5) cm. Median RENAL score was 9 (8-10). Median ischemia time was 25 (20-32) min. Median estimated blood loss was 150 (100-300) ml. Sixteen patients had intraoperative complications (5.4%), whereas 66 (22%) had postoperative complications (5% were Clavien grade ≥3). Multivariable analysis revealed that a lower RENAL score (odds ratio [OR] 0.46, 95% confidence interval [CI] 0.21-0.65, p=0.02) and pathological pT2 stage (OR 0.51, 95% CI 0.12-0.86, p=0.001) were protective against postoperative complications. A total of 243 lesions (82%) were malignant. Twenty patients (8%) had positive surgical margins. Ten deaths and 25 recurrences/metastases occurred at a median follow-up of 12 (5-35) mo. At univariable analysis, higher pT stage was predictive of a likelihood of recurrences/metastases (p=0.048). While there was a significant deterioration of renal function at discharge, this remained stable over time at 1-yr follow-up. The main limitation of this study is its retrospective design. RAPN in the setting of select cT2 renal masses can safely be performed with acceptable outcomes. Further studies are warranted to corroborate our findings and to better define the role of robotic nephron sparing for this challenging indication. This report shows that robotic surgery can be used for safe removal of a large renal tumor in a minimally invasive fashion, maximizing preservation of renal function, and without compromising cancer control.

Introduction. The aim of our work was to investigate the causal connection between M1 and M2 macrophage phenotypes occurrence and prostate cancer, their correlation with tumor extension (ECE), and biochemical recurrence (BR).Patient and Methods. Clinical and pathological data were prospectively gathered from 93 patients treated with radical prostatectomy. Correlations of commonly used variables were evaluated with uni- and multivariate analysis. The relationship between M1 and M2 occurrence and BR was also assessed with Kaplan-Meier survival analysis.Results. Above all in 63.4% there was a M2 prevalence. M1 occurred more frequently in OC disease, while M2 was more represented in ECE. At univariate analysis biopsy and pathologic GS and M2 were statistically correlated with ECE. Only pathologic GS and M2 confirmed to be correlated with ECE. According to macrophage density BCR free survival curves presented a statistically significant difference. When we stratified our population for M1 and M2,we did not find any statistical difference among curves. At univariate analysis GS, pTNM, and positive margins resulted to be significant predictors of BCR, while M1 and M2 did not achieve the statistical significance. At multivariate analysis, only GS and pathologic stage were independent predictors of BR.Conclusion. In our study patients with higher density of M count were associated with poor prognosis; M2 phenotype was significantly associated with ECE.

Purpose To review the currently available literature reporting the patterns of recurrence and their predictive factors after open radical cystectomy (RC) for bladder cancer. Methods A review of the literature was performed using the MEDLINE, Scopus and Web of Sciences databases from January 1997 to May 2017. The PRISMA guidelines were followed for the conduct of the study. Results Local recurrence rate ranges between 30 and 54%. Distant recurrence is not often standardized and is reported in up to 50% of cases. The overall 5-year recurrence-free survival rates from 58 to 81%. The mean follow-up of studies included in the analysis ranged from 18 to 350 months. Details on the most important demographic and epidemiological, clinical, histologic and pathologic predictors of recurrence after radical cystectomy are provided through an evidence-based approach. The impact of the extension of lymph node dissection on recurrence after RC is investigated. Conclusions A correct prognostic assessment is essential for patients undergoing radical cystectomy for bladder cancer, thereby potentially improving their oncologic outcomes.
