Abstract
Introduction High-dose local stereotactic robotic radiosurgery (RRS) is a non-invasive alternative to surgery in renal masses and selected patients. We have, so far, limited its use to the elderly and patients at high risk from surgery. In this study, we matched patients with renal tumors who were treated with single fraction RRS to patients who underwent open partial nephrectomy (OPN). Methods Between January 2009 and December 2017, we included 571 consecutive patients undergoing OPN and 99 patients who underwent RRS in this retrospective analysis. Patients had to have a follow-up of at least six months and we were able to match 35 with a propensity score. Matching criteria were Eastern Cooperative Oncology Group (ECOG) status, age, clinical tumor, nodes, and metastases (TNM), and tumor diameter. Tumor response, renal function, survival, and adverse events were evaluated every three months until progression or death. Results Median age was 65 years for RRS (range 58-75) and 71 (range 56-76) for OPN (p=0.131). Median diameter of renal tumors was 2.8 cm (range 2.4-3.9) for RRS and 3.5 cm (2.8-4.5) for OPN, p=0.104. Median follow-up was 28.1 months (range 6.0-78.3 months). Local tumor control nine months after RRS and OPN was 98% (95% CI: 89-99%). Renal function remained stable with a median creatinine clearance (Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI)) at baseline of 76.8mlmin/1.73m2 (range 25.3-126.3) and 70.3ml/min/1.73m2 (range 18.6-127.3) at follow-up (p=0.89). Median overall survival was not reached. No difference in overall survival (OS) was seen in RRS compared to OPN (p=0.459). Conclusions Single fraction RRS is an alternative to OPN in patients unfit for surgery. Oncological and functional results are comparable to those of OPN. Further studies are needed to determine long-term results and limits of RRS in this setting and in younger patients.

Abstract
PURPOSE To compare the tumor growth kinetics between sporadic clear cell renal cell carcinoma (ccRCC) and Von Hippel-Lindau disease-associated renal cell carcinoma (VHL-associated RCC). To analyze predictive markers for the growth rate of these two types of RCC. METHODS The clinical data of patients with renal tumors who received active surveillance were collected retrospectively. Immunohistochemical staining was utilized to analyze the expression levels of VHL, PBRM1, H3K36me3, and BAP1 in the postoperative specimens. RESULTS The age of the VHL group was significantly younger than that of the sporadic group (P < 0.0001). The mean linear growth rate (LGR) was significantly faster in the sporadic group (P = 0.0004). The tumors of those in the sporadic group tended to have a higher histologic grade (P = 0.0011). In the sporadic group, tumor histologic grade was an independent predictor for rapid mean LGR (P = 0.0022). In the VHL group, initial maximal tumor diameter (MTD) was the only independent predictor for rapid mean LGR (P < 0.0001). Tumors with low VHL expression and negative PBRM1 expression showed a faster growth rate in the sporadic group (P = 0.001 and P = 0.008, respectively). The expression levels of the four biomarkers showed no impact on the tumor growth rate in the VHL group. CONCLUSION Sporadic ccRCC grew faster than VHL-associated RCC. High histologic grade, low VHL expression and negative PBRM1 expression were predictors of faster growth in sporadic ccRCC. A large initial MTD was a predictor of faster growth for VHL-associated RCC.

The effect of delaying nephrectomy on oncologic outcomes in patients with renal tumors greater than 4cm. Urol Oncol 2016; 34:239.e1-8. [PMID: 26795607 DOI: 10.1016/j.urolonc.2015.12.001] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2015] [Revised: 11/07/2015] [Accepted: 12/06/2015] [Indexed: 01/16/2023]
Abstract
OBJECTIVES Delaying nephrectomy<3 months does not adversely affect treatment outcome of renal tumors. Whether surgical waiting time (SWT; time from diagnosis to surgery)>3 months affects treatment outcome for large renal masses has not been well studied. We aimed to evaluate if SWT is associated with treatment outcome of renal masses >4cm and identify patients who are more likely to experience prolonged SWT. MATERIALS AND METHODS Data from 1,484 patients undergoing radical or partial nephrectomy at a single institution for a nonmetastatic renal mass>4cm between 1995 and 2013 were reviewed. Patients with benign tumors and incomplete preoperative data were excluded. The association between SWT and disease upstaging at the time of surgery and recurrence at 2 and 5 years was assessed using logistic regression. Cancer-specific survival (CSS) and overall survival were assessed with landmark survival analyses and multivariable Cox proportional hazards models. All analyses were adjusted for patient and tumor characteristics. RESULTS Of the final cohort of 1,278 patients, 267 (21%) had SWT>3 months. Patients with larger, symptomatic tumors had shorter SWT. Median follow-up for survivors was 3.8 years (interquartile range: 1.5-7.4). On multivariable analysis, SWT was not associated with disease upstaging, recurrence, or CSS. Longer SWT was associated with decreased overall survival (hazard ratio = 1.17; 95% CI: 1.08-1.27; P = 0.0002). Sex and tumor size, histology, and presentation were associated with disease upstaging, recurrence, and CSS. The most common cause for surgical delay>3 months was evaluation and treatment of comorbidities. CONCLUSION Patient and tumor characteristics, rather than SWT, were associated with disease upstaging, recurrence, and CSS, and should guide the decision to delay surgery when treating nonmetastatic renal tumors>4cm.
