Ambiguity exists regarding the definition of a level III inferior vena cava tumor thrombus (IVC-TT), limiting comparisons between open and minimally-invasive series. We assessed 253 patients who underwent radical nephrectomy with IVC-TT from 2000-2015 and proposed a modified classification based on associations between intraoperative IVC clamp position and need for cardiopulmonary bypass with complications, length of stay, and blood transfusions. Predictive ability of the modified system was not meaningfully improved (AUCs 0.59–0.58; 0.61–0.61; 0.72–0.72). Nevertheless, we advocate for standardization of the border of a level III thrombus at or above the major hepatic veins to facilitate meaningful comparisons between techniques.

. Background: We investigated outcomes with cabozantinib versus everolimus in patients with advanced renal cell carcinoma (RCC) with or without prior nephrectomy in the phase 3 METEOR trial (NCT01865747). Methods: Patients (N=658) with advanced clear cell RCC and prior treatment with ≥ 1 VEGFR tyrosine kinase inhibitor (TKI) were randomized to cabozantinib 60mg/day or everolimus 10mg/day. Pre-specified subgroup analyses of progression-free survival (PFS), overall survival (OS), and objective response rate (ORR) were conducted by prior nephrectomy status. Response was assessed by independent radiology committee. Results: Most enrolled patients (85%) had prior nephrectomy. Baseline prognostic factors (e.g. MSKCC risk group) were less favorable for patients without prior nephrectomy. Cabozantinib improved outcomes versus everolimus in the subgroups with and without nephrectomy— hazard ratios (95% CIs) of 0.51 (0.41–0.64) and 0.51 (0.30–0.86), respectively, for PFS, and 0.66 (0.52–0.84) and 0.75 (0.44–1.27), respectively, for OS. Median OS was numerically longer in patients with versus those without prior nephrectomy in both treatment arms. ORR for cabozantinib versus everolimus was 17% versus 4% for the prior nephrectomy subgroup and 21% versus 2% for the subgroup without prior nephrectomy. Among evaluable patients without prior nephrectomy, reductions of renal target lesions occurred in 94% (16/17) of patients in the cabozantinib arm versus 44% (8/18) in the everolimus arm. The safety profiles of both subgroups were generally consistent with that of the overall study population. Conclusion: Cabozantinib improved PFS, ORR, and OS compared with everolimus in patients with advanced RCC irrespective of nephrectomy status.

BACKGROUND: Cabozantinib is an oral multitargeted tyrosine kinase inhibitor (TKI) that has demonstrated efficacy in metastatic renal-cell carcinoma (mRCC) randomized trials. OBJECTIVE: To explore the real-world effectiveness of cabozantinib in pretreated patients with mRCC, including patients who progressed on immune-oncology checkpoint inhibitor (ICI) therapy. METHODS: Using the Canadian Kidney Cancer information system (CKCis), patients with mRCC treated with cabozantinib monotherapy as second-line or later from January 1, 2011 to September 1, 2019 were identified. Patients were stratified based on line of cabozantinib received. We reported overall survival (OS), time to treatment failure (TTF) and disease control rate (DCR). Prognostic variables were analyzed using multivariable analysis. RESULTS: 157 patients received cabozantinib (median TTF 8.0 months; median OS 15.8 months): 37 (24%) in the second line (median TTF 10.4 months; median OS 18.9 months) 66 (42%) in third line (median TTF 5.9 months; median OS 13.3 months) and 54 (34%) in either 4th or 5th line (median TTF 9.4 months; median OS 16.8 months). One hundred sixteen patients (74%) received cabozantinib after prior ICI therapy (median TTF of 7.6 months; median OS of 15.8 months). DCR in all patients was 63% with 46%, 65% and 72% in 2nd line, 3rd line and 4th/5th line patients respectively. DCR in patients who received cabozantinib after prior ICI therapy was 64%. CONCLUSIONS: Cabozantinib is effective in a real-world, unselected population of mRCC patients, including in those who have progressed on prior ICI therapy, and in those exposed to multiple lines of therapy.

With the improved knowledge of molecular oncology and the introduction of targeted therapies as well as immunotherapies, there has been significant progress in the treatment of patients with metastatic renal cell carcinoma (mRCC). At present, treatment decisions are still made mainly based on clinical factors because no validated prognostic and predictive biomarkers for mRCC exist. Currently, inflammatory markers, genetic markers, and immune checkpoint molecules are candidate biomarkers for more personalized treatment of mRCC. RCC has been considered to be an inflammatory tumor and its underlying inflammatory mechanism would play some roles in forming resistance to systemic therapy. The von Hippel-Lindau (VHL) gene is inactivated by either mutation or methylation in over 80% of clear cell RCC (ccRCC). Thus, most, if not all, ccRCC may have deregulation of the VHL pathway. For some reason, VHL status is difficult to use as a prognostic marker. Polybromo 1 (PBRM1) is the second most frequently mutated gene in ccRCC and loss of function mutations in the PBRM1 gene have been shown to be associated with improved survival in patients with mRCC treated with systemic therapies. The expression of programmed death ligand 1 (PD-L1) on tumor cells in RCC seems to be associated with a higher tumor stage, a worse response to tyrosine kinase inhibitor (TKI) therapy, and a worse prognosis. Future challenges are required to develop and validate predictive biomarkers in order to establish a more personalized treatment for mRCC.

The treatment landscape of metastatic renal cell carcinoma (mRCC) is evolving very rapidly. Until recently, targeted monotherapy with vascular endothelial growth factor (VEGF)-tyrosine kinase inhibitors (TKIs) such as sunitinib, pazopanib and cabozantinib were considered the predominant frontline treatment options. In 2018, combination immune checkpoint inhibitor (ICI) therapy with ipilimumab and nivolumab was approved by the United States’ Food and Drug Administration (FDA) for intermediateand poor-risk patients. Subsequently, the FDA approved combination regimens consisting of a VEGFTKI with an immune checkpoint inhibitor for all risk categories: pembrolizumab-axitinib and avelumb-axitinib. In the context of these new developments and several ongoing trials in treatment naı̈ve clear-cell mRCC, there remains a dilemma among treating physicians about the choice of the most appropriate therapy as well as how to sequence these agents. In this review, we aim to highlight the available data on immunotherapy-based combinations and to provide a contemporary perspective on the optimal approach to patients with mRCC.

Introduction: Collecting duct carcinomas (CDC), also known as Bellini’s tumors, are a rare and aggressive subtype of renal cell carcinoma. Therefore, there are very few data about their management, and there is no standard therapy for this malignancy. We report the outcome of CDC patients treated on institutions belonging to the ‘Grupo Centro’ of Genitourinary Tumors, a novel networking cooperative group in Spain. Material and Methods: Patients with CDC diagnosed between 1995 and 2015 were included. They had to have an appropriate follow-up, as well as available tissue for further correlative studies. Demographic baseline features and therapy outcomes were collected in a retrospective fashion. Approval for this data collection was obtained from a central ethical committee. Results: A total of 43 patients were analysed, with a median overall survival (OS) of 14 months (95% CI: 9.2–18.8 months). 29 of them (67.4%) were diagnosed as localized disease, and 14 (32.6%) as metastatic disease. For the subgroup of patients diagnosed without metastases, median relapse-free survival (RFS) is 22 months (95% CI: 12.4–35.6 months), and median OS, 53 months (95% CI: 35.5–84.3 months). For the subgroup of patients with metastatic disease, median OS is 6 months (95% CI: 4.1–7.8 months). 16 patients (55.2%) with stage IV disease received systemic therapy, mainly platinum-based chemotherapy, with a response rate of 12.5% and a median progression-free survival (PFS) of 2 months. Conclusions: CDC of the kidney is a malignancy with poor prognosis and few responses to therapy. Median OS of our group in the metastatic setting is similar to what has been observed in previous series. There is a clear need to improve the armamentarium we have for the systemic approach of patients with advanced CDC.
