RESUMO
BACKGROUND: The Lung Immune Prognostic Index (LIPI) is associated with immune checkpoint inhibitors (ICI) outcomes across different solid tumors, particularly in non-small cell lung cancer. Data regarding the prognostic and/or predictive role of LIPI in metastatic renal cell carcinoma (mRCC) are still scarce. The aim of this study was to evaluate whether LIPI could be predictive of survival in mRCC patients. METHODS: We used patient level data from three different prospective studies (NIVOREN trial: nivolumab; TORAVA trial: VEGF/VEGFR-targeted therapy (TT); CheckMate 214: nivolumab-ipilimumab vs sunitinib). LIPI was calculated based on a derived neutrophils/(leukocyte-neutrophil) ratio > 3 and lactate-dehydrogenase >upper limit of normal, classifying patients into three groups (LIPI good, 0 factors;LIPI intermediate (int), 1 factor;LIPI poor, 2 factors) and/or into two groups (LIPI good, 0 factors;LIPI int/poor, 1-2 factors) according to trial sample size. Primary and secondary endpoints were overall survival (OS) and progression-free survival (PFS). RESULTS: In the Nivolumab dataset (n = 619), LIPI was significantly associated with OS (LIPI-good 30.1 vs 13.8 months in the LIPI int/poor; HR= 0.47) and PFS (HR=0.74). In the VEGF/VEGFR-TT dataset (n = 159), only a correlation with PFS was observed. In the CheckMate214 dataset (n = 1084), LIPI was significantly associated with OS (nivolumab-ipilimumab OS LIPI good vs int/poor: HR=0.55, p < 0.0001; sunitinib: OS LIPI good vs int/poor: 0.38, p < 0.0001) in both treatment groups in univariate and multivariate analysis. CONCLUSIONS: Pretreatment-LIPI correlated with worse survival outcomes in mRCC treated with either ICI or antiangiogenic therapy, confirming LIPI's prognostic role in mRCC irrespective of systemic treatment used.

INTRODUCTION: Immune checkpoint inhibitors are standard of care in metastatic renal cell carcinoma but their activity and safety in elderly patients is insufficiently explored. We evaluated outcomes of elderly patients with mRCC treated with nivolumab in the GETUG-AFU 26 NIVOREN phase 2 trial (NCT03013335) and conducted exploratory circulating biomarker analyses. METHODS: Patients with mRCC were treated with nivolumab after at least one antiangiogenic therapy. The main endpoint of this analysis was safety in patients ≥ 70 years old (y.o), as per the rate of treatment-related grade 3-5 events (TRAE). Secondary endpoints included overall response rate (ORR), progression-free survival (PFS), overall survival. Exploration of candidate biomarkers associated with aging included baseline circulating cytokines involved in inflammation, adhesion, immune checkpoints, angiogenesis (IL6, IL7, IL8, BAFF, CXCL13, VCAM-1, 4-1BB, VEGF). RESULTS: Of 720 patients, 515 were < 70 y.o and 205 ≥ 70 y.o. Patients ≥ 70 y.o exhibited numerically less IMDC poor risk disease (21.0% vs 26.9%), sarcomatoid component (4.9% vs 9.8%) or brain metastases (5.9% vs. 14.7%), but more previous treatment lines (≥ 2 in 54.1% vs 48.5%). TRAE were higher in patients ≥ 70 y.o (24.9% vs. 17.9%, p = 0.033). Respective ORR (19.2% vs. 22.1%) and median PFS (4.5 versus 3.0 months, HR 0.97 [95%CI 0.81-1.15]) were similar. Overall survival was shorter in patients ≥ 70 y.o (19.3 versus 26.9 months, HR 1.26 [95%CI 1.04-1.51]), but not significantly in a competitive risk model. Only V-CAM1 and 4-1BB were found to be increased in patients ≥ 70 y.o. CONCLUSIONS: Nivolumab displayed higher grade 3/4 TRAE but manageable toxicity in elderly patients, with sustained activity. Elderly patients did not display specific inflammatory or angiogenic circulating profiles.

BACKGROUND: Treatment landscape for advanced renal cell carcinoma (aRCC) has evolved quickly and few data about the real-world treatment patterns are available. This study aimed at describing the real-world treatment patterns and effectiveness of all systemic treatments available for aRCC in first and second-line treatment. MATERIALS AND METHODS: A cohort of patients initiating a first-line systemic treatment for aRCC in 2016 was extracted from the French nationwide healthcare insurance system database (SNDS). The first-line treatment initiation date constituted the index date and patients were followed until death, loss to follow-up, or December 31, 2019, whichever occurred first. aRCC was identified using hospital diagnosis, long-term disease, or renal biopsy before index date. All analyses were performed for first and second-line treatment. Overall survival (OS) and time-to-next treatment or death (TNT-D) were estimated using Kaplan-Meier approach. RESULTS: In 2016, 1629 patients initiated a first-line treatment for aRCC. Most of them were male (75.9%) and the median age was 67 years. Most of patients (91.7%) had received a tyrosine kinase inhibitor as first-line treatment, mainly sunitinib (64.4%), and 53.5% received a second-line, among which 43.7% nivolumab. Median OS (95% confidence interval [CI]) was 20.7 (95% CI:18.2-22.4) months from first-line treatment initiation and 15.4 (13.9-17.5) months from second-line treatment initiation. Median TNT-D were respectively 9.3 (9.7-12.1) months and 6.9 (5.9-7.7) months. CONCLUSION: This study highlights the limited survival of aRCC patients These results provide a valuable baseline and highlight the need for innovation, such as immune checkpoint inhibitor-based combinations that have recently became first-line standard of care.

BACKGROUND: Papillary renal cell carcinoma (pRCC) is the most common non-clear cell RCC, and associated with poor outcomes in the metastatic setting. In this study, we aimed to comprehensively evaluate the immune tumor microenvironment (TME), largely unknown, of patients with metastatic pRCC and identify potential therapeutic targets. METHODS: We performed quantitative gene expression analysis of TME using Microenvironment Cell Populations-counter (MCP-counter) methodology, on two independent cohorts of localized pRCC (n=271 and n=98). We then characterized the TME, using immunohistochemistry (n=38) and RNA-sequencing (RNA-seq) (n=30) on metastatic pRCC from the prospective AXIPAP trial cohort. RESULTS: Unsupervised clustering identified two "TME subtypes", in each of the cohorts: the "immune-enriched" and the "immune-low". Within AXIPAP trial cohort, the "immune-enriched" cluster was significantly associated with a worse prognosis according to the median overall survival to 8 months (95% CI, 6 to 29) versus 37 months (95% CI, 20 to NA, p=0.001). The two immune signatures, Teff and JAVELIN Renal 101 Immuno signature, predictive of response to immune checkpoint inhibitors (CPI) in clear cell RCC, were significantly higher in the "immune-enriched" group (adjusted p<0.05). Finally, five differentially overexpressed genes were identified, corresponding mainly to B lymphocyte populations. CONCLUSION: For the first time, using RNA-seq and immunohistochemistry, we have highlighted a specific immune TME subtype of metastatic pRCC, significantly more infiltrated with T and B immune population. This "immune-enriched" group appears to have a worse prognosis and could have a potential predictive value for response to immunotherapy, justifying the confirmation of these results in a cohort of metastatic pRCC treated with CPI and in combination with targeted therapies. TRIAL REGISTRATION NUMBER: NCT02489695.

BACKGROUND: Glandular metastases (GMs; adrenal gland, pancreas, thyroid, ovary, breast, or prostate) are rare in metastatic clear cell renal cell carcinoma (mccRCC). Previous studies have indicated that GM patients treated with antiangiogenic therapy experience significantly longer overall survival (OS). OBJECTIVES: To assess outcomes for mccRCC with or without GMs treated with nivolumab. DESIGN, SETTING, AND PARTICIPANTS: The GETUG-AFU-26 NIVOREN phase 2 trial evaluated the activity and safety of nivolumab in patients with mccRCC who experienced failure of antiangiogenic therapies (NCT03013335). In this ancillary study, patients were divided into two groups according to the presence or absence of at least one GM. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was OS; secondary outcomes were progression-free survival (PFS) and the objective response rate (ORR). Survival was estimated using the Kaplan-Meier method. Univariate and multivariable Cox regression models are used to estimate the hazard ratio (HR) with 95% confidence interval (CI) for survival outcomes. Subgroup analyses were performed for patients with pancreatic metastases and patients with adrenal metastases. RESULTS AND LIMITATIONS: Among 720 patients treated with nivolumab between February 2016 and July 2017, 217 had GMs, of whom 151/217 had adrenal metastases and 86/217 had pancreatic metastasis. Patients with adrenal metastases had worse 12-mo OS (64% vs 71.1%) and 6-mo PFS (27.2% vs 36.6%) and a lower objective response rate (12.5%, 95% CI 7.6%-19.0%, vs 23.2%, 95% CI 19.8-27.0%; p = 0.005) than patients without adrenal metastases. Conversely, univariate analysis showed that patients with pancreatic metastases had significantly better 12-mo OS (82.3% vs 67.9%; HR 0.59, 95% CI 0.40-0.85) in comparison to patients with nonpancreatic GMs. On multivariable analysis, only adrenal metastasis remained associated with adverse prognosis. CONCLUSIONS: Adrenal metastasis is an independent prognostic factor for poor response and survival in the GETUG-AFU-26 NIVOREN trial. Limited activity with nivolumab was observed for patients with mccRCC with adrenal metastases. These results warrant an evaluation of the prognostic value of adrenal metastases in patients treated with immunotherapy combinations with ipilimumab or tyrosine kinase inhibitors. PATIENT SUMMARY: Our study showed that metastasis in the adrenal glands could be an independent factor associated with poor response to immunotherapy and survival for patients with metastatic kidney cancer. It would be useful to evaluate the prognostic value of adrenal gland metastasis in patients treated with immunotherapy combinations or immunotherapy agents combined with drugs called tyrosine kinase inhibitors.
RESUMO
BACKGROUND: In metastatic renal clear cell carcinoma (ccRCC), vascular endothelial growth factor receptor (VEGFR) and immune checkpoint are 2 main therapeutic targets. We investigated the impact of duration exposure to antiangiogenic on immunotherapy clinical outcomes in metastatic ccRCC. METHODS: Patients from NIVOREN trial who received nivolumab after only 1 prior antiangiogenic therapy were included. Response rate, clinical benefit, progression free survival (PFS) and overall survival (OS) were prospectively analyzed depending on the duration of the first line (< 6 months, ≥6 months) and exploratory in patients with long first line exposure (≥18 months). The circulating levels of 8 plasma proteins and cytokines at baseline were collected and compared according to first line antiangiogenic duration. RESULTS: Among 354 patients, 127 (36%) and 227 (64%) patients had received first line antiangiogenic for < 6months and ≥ 6months respectively. Respective duration of first line therapy was not associated with objective response to nivolumab (20.5% vs. 23.9%, P = .50), or PFS (HR 0.92; P = .421). Median OS was respectively 16.6 and 31.3 months in the <6 and ≥6 months subgroups respectively. Adjusted on international metastatic renal cell carcinoma database consortium risk, age and metastatic site, OS was longer in patients with longer treatment duration in the first line setting (HR 0.73; P = .017). Duration of first line VEGFR TKI was independent from circulating levels of 8 proteins and cytokines at nivolumab baseline. CONCLUSION: Nivolumab activity in second line is independent from first-line duration of VEGFR TKI. However, first line VEGFR TKI duration ≥ 6 months is associated with longer OS.

PURPOSE: A randomized, phase III trial demonstrated superiority of sunitinib over interferon alfa (IFN-α) in progression-free survival (primary end point) as first-line treatment for metastatic renal cell carcinoma (RCC). Final survival analyses and updated results are reported. PATIENTS AND METHODS: Seven hundred fifty treatment-naïve patients with metastatic clear cell RCC were randomly assigned to sunitinib 50 mg orally once daily on a 4 weeks on, 2 weeks off dosing schedule or to IFN-α 9 MU subcutaneously thrice weekly. Overall survival was compared by two-sided log-rank and Wilcoxon tests. Progression-free survival, response, and safety end points were assessed with updated follow-up. RESULTS: Median overall survival was greater in the sunitinib group than in the IFN-α group (26.4 v 21.8 months, respectively; hazard ratio [HR] = 0.821; 95% CI, 0.673 to 1.001; P = .051) per the primary analysis of unstratified log-rank test (P = .013 per unstratified Wilcoxon test). By stratified log-rank test, the HR was 0.818 (95% CI, 0.669 to 0.999; P = .049). Within the IFN-α group, 33% of patients received sunitinib, and 32% received other vascular endothelial growth factor-signaling inhibitors after discontinuation from the trial. Median progression-free survival was 11 months for sunitinib compared with 5 months for IFN-α (P < .001). Objective response rate was 47% for sunitinib compared with 12% for IFN-α (P < .001). The most commonly reported sunitinib-related grade 3 adverse events included hypertension (12%), fatigue (11%), diarrhea (9%), and hand-foot syndrome (9%). CONCLUSION: Sunitinib demonstrates longer overall survival compared with IFN-α plus improvement in response and progression-free survival in the first-line treatment of patients with metastatic RCC. The overall survival highlights an improved prognosis in patients with RCC in the era of targeted therapy.
RESUMO
PURPOSE: To describe the incidence, management, and survival outcomes of patients with muscle-invasive urothelial carcinoma (MIUC) undergoing radical surgery (RS) in France. METHODS: We relied on a non-interventional real-world retrospective study based on French National Hospitalization Database. Adults with MIUC with a first RS between 2015 and 2020 were selected. Subpopulations of patients with RS performed in 2015 and 2019 (pre-COVID-19) were extracted, according to cancer site: muscle-invasive bladder cancer (MIBC) or upper tract urothelial carcinoma (UTUC). Disease-free and overall survival (DFS, OS - Kaplan-Meier) were assessed on the 2015 subpopulation. RESULTS: Between 2015 and 2020, 21,295 MIUC patients underwent a first RS. Of them, 68.9% had MIBC, 28.9% UTUC, and 2.2% both cancers. Apart from fewer men among UTUC (70.2%) than MIBC patients (90.1%), patients' demographic (mean age ~ 73 years) and clinical characteristics were similar whatever the cancer site or year of first RS. In 2019, RS alone was the most frequent treatment, occurring in 72.3% and 92.6% in MIBC and UTUC, respectively. Between 2015 and 2019, neoadjuvant use rate increased from 13.8% to 22.2% in MIBC, and adjuvant use rate increased from 3.7% to 6.3% in UTUC. Finally, median [95% confidence interval] DFS times were 16.0 [14.0-18.0] and 27.0 [23.0-32.0] months among MIBC and UTUC, respectively. CONCLUSION: Among patients with resected MIUC annually, RS alone remained the main treatment. Neoadjuvant and adjuvant use increased between 2015 and 2019. Nonetheless, MIUC remains of poor prognosis, highlighting an unmet medical need, notably among patients at high risk of recurrence.

The efficacy of anti-angiogenic treatment by targeting VEGF/VEGF receptors in metastatic clear cell renal cell carcinoma (ccRCC) varies from patient to patient. Discovering the reasons behind this variability could lead to the identification of relevant therapeutic targets. Thus, we investigated the novel splice variants of VEGF that are less efficiently inhibited by anti-VEGF/VEGFR targeting than the conventional isoforms. By in silico analysis, we identified a novel splice acceptor in the last intron of the VEGF gene resulting in an insertion of 23 bp in VEGF mRNA. Such an insertion can shift the open-reading frame in previously described splice variants of VEGF (VEGFXXX ), leading to a change in the C-terminal part of the VEGF protein. Next, we analysed the expression of these alternatively spliced VEGF new isoforms (VEGFXXX/NF ) in normal tissues and in RCC cell lines by qPCR and ELISA, and we investigated the role of VEGF222/NF (equivalent to VEGF165 ) in physiological and pathological angiogenesis. Our in vitro data demonstrated that recombinant VEGF222/NF stimulated endothelial cell proliferation and vascular permeability by activating VEGFR2. In addition, VEGF222/NF overexpression enhanced proliferation and metastatic properties of RCC cells, whereas downregulation of VEGF222/NF resulted in cell death. We also generated an in vivo model of RCC by implanting RCC cells overexpressing VEGF222/NF in mice, which we treated with polyclonal anti-VEGFXXX/NF antibodies. VEGF222/NF overexpression enhanced tumour formation with aggressive properties and a fully functional vasculature, while treatment with anti-VEGFXXX/NF antibodies slowed tumour growth by inhibiting tumour cell proliferation and angiogenesis. In a patient cohort from the NCT00943839 clinical trial, we investigated the relationship between plasmatic VEGFXXX/NF levels, resistance to anti-VEGFR therapy and survival. High plasmatic VEGFXXX/NF levels correlated with shorter survival and lower efficacy of anti-angiogenic drugs. Our data confirmed the existence of new VEGF isoforms that could serve as novel therapeutic targets in patients with RCC that are resistant to anti-VEGFR therapy.

INTRODUCTION: Bone metastases (BM) in renal cell carcinoma (RCC) are associated with a poor prognosis based on retrospective studies evaluating antiangiogenic agents. Few data are available regarding immune checkpoint inhibitors (ICI) in patients with bone metastatic RCC. NIVOREN is a multicentre prospective study in which patients were treated with nivolumab after the failure of antiangiogenic agents. We aim to assess the impact of BM on prognosis, and the efficacy and safety of nivolumab in patients enrolled in the NIVOREN trial. MATERIALS AND METHODS: All patients with BM at inclusion were included in our study. The primary endpoint was overall survival (OS). Secondary endpoints were progression-free survival (PFS), objective response rate (ORR), safety, and skeletal-related events (SRE). RESULTS: Among 720 patients treated with nivolumab, 194 presented BM at inclusion. The median follow-up was 23.9 months. Median OS was 17.9 months in patients with BM versus 26.1 months in patients without BM (p = 0.0023). The difference was not statistically significant after adjustment (p = 0.0707). The median PFS was shorter in patients with BM even after adjustment (2.8 versus 4.6 months, p = 0.0045), as well as the ORR (14.8% versus 23.3%). SRE occurred for 36% of patients with BM. A post-hoc analysis evaluating the impact of bone-targeting agents (BTA) on SRE incidence showed a significant benefit of BTA on the incidence of SRE (OR = 0.367, CI95% [0.151-0.895]). CONCLUSION: Nivolumab is associated with shorter PFS, and lower ORR in RCC patients with BM. Our study suggests that BTA in association with immunotherapy decreases the incidence of SRE.

BACKGROUND: There remains a paucity of data regarding the efficacy of immune checkpoint therapy (ICT) combinations ± vascular endothelial growth factor (VEGF) targeted therapy (TT) in translocation renal cell carcinoma (tRCC). METHODS: This is a retrospective study of patients with advanced tRCC treated with ICT combinations at 11 centers in the US, France, and Belgium. Only cases with confirmed fluorescence in situ hybridization (FISH) were included. Objective response rates (ORR) and progression-free survival (PFS) were assessed by RECIST, and overall survival (OS) was estimated by Kaplan-Meier methods. RESULTS: There were 29 patients identified with median age of 38 (21-70) years, and F:M ratio 0.9:1. FISH revealed TFE3 and TFEB translocations in 22 and 7 patients, respectively. Dual ICT and ICT + VEGF TT were used in 18 and 11 patients, respectively. Seventeen (59%) patients received ICT combinations as first-line therapy. ORR was 1/18 (5.5%) for dual ICT and 4/11 (36%) for ICT + VEGF TT. At a median follow-up of 12.9 months, median PFS was 2.8 and 5.4 months in the dual ICT and ICT + VEGF TT groups, respectively. Median OS from metastatic disease was 17.8 and 30.7 months in the dual ICT and ICT + VEGF TT groups, respectively. CONCLUSION: In this retrospective study of advanced tRCC, limited response and survival were seen after frontline dual ICT combination therapy, while ICT + VEGF TT therapy offered some efficacy. Due to the heterogeneity of tRCC, insights into the biological underpinnings are necessary to develop more effective therapies.

INTRODUCTION: Metastatic non clear cell renal cell carcinoma (nccRCC) is an heterogenous group, usually excluded from phase 3 trials. We report real life data of prognosis and systemic management of those patients. METHODS: We retrospectively included 102 metastatic nccRCC patients (unspecified papillary, n = 10; type 1 and 2 papillary n = 10 and n = 32; translocation RCC, n = 9; chromophobe, n = 14; collecting duct, n = 14) treated between 2006 and 2020. Objective response rate (ORR), progression-free survival (PFS) and overall survival (OS) were evaluated. RESULTS: Among patients who underwent pathological review, 40.8% presented a complete histological discordance. First line treatments were mainly tyrosine kinase inhibitor (60.8%), combination including immunotherapy (7.8%) or combination of chemotherapy (13.7%). Median ORR ranged from 0% in unspecified papillary RCC to 42.9% in type 1 papillary RCC. Median PFS ranged from 2.9 months in collecting duct carcinoma to 10.9 months in type 1 papillary RCC. Median OS ranged from 6.8 months in collecting duct carcinoma to 29.1 months in MiT family translocation RCC. Thirty (29.4%) patients were included in a treatment trial during their treatment course. CONCLUSION: Metastatic nccRCC patients have variable prognosis due to heterogeneity of histological subtypes. Their diagnosis and access to therapeutic innovation remain suboptimal. Dedicated prospective trials are needed.

BACKGROUND: MiT family translocation renal cell carcinoma (TRCC) is a rare and aggressive subgroup of renal cell carcinoma harboring high expression of c-MET. While TRCC response rates to VEGF receptor tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors are limited, efficacy of cabozantinib (a VEGFR, MET, and AXL inhibitor) in this subgroup is unclear. METHODS: We performed a multicenter, retrospective, international cohort study of patients with TRCC treated with cabozantinib. The main objectives were to estimate response rate according to RECIST 1.1 and to analyze progression-free survival (PFS) and overall survival (OS). RESULTS: Fifty-two patients with metastatic TRCC treated in the participating centers and evaluable for response were included. Median age at metastatic diagnosis was 40 years (IQR 28.5-53). Patients' IMDC risk groups at diagnosis were favorable (9/52), intermediate (35/52), and poor (8/52). Eleven (21.2%) patients received cabozantinib as frontline therapy, 15 (28.8%) at second line, and 26 (50%) at third line and beyond. The proportion of patients who achieved an objective response was 17.3%, including 2 complete responses and 7 partial responses. For 26 (50%) patients, stable disease was the best response. With a median follow-up of 25.1 months (IQR 12.6-39), median PFS was 6.8 months (95%CI 4.6-16.3) and median OS was 18.3 months (95%CI 17.0-30.6). No difference of response was identified according to fusion transcript features. CONCLUSION: This real-world study provides evidence of the activity of cabozantinib in TRCC, with more durable responses than those observed historically with other VEGFR-TKIs or ICIs.

INTRODUCTION: Proton pump inhibitors (PPI) may influence the gut microbiome and thus impact the effectiveness of immune checkpoint inhibitors (ICI). The effect of PPIs on the outcomes of ICI has not been fully explored and investigated in metastatic renal cell carcinoma (mRCC). METHODS: This retrospective analysis used prospectively collected data from the GETUG-AFU 26 NIVOREN (NCT03013335) phase II study which enrolled 729 mRCC patients of whom 720 were treated with nivolumab. The main objective of this analysis was to evaluate the impact of PPI on the efficacy and safety outcomes of mRCC patients. PPI use was defined as PPI administration on the day of ICI initiation. RESULTS: Of the 707 patients with mRCC analyzed in this study, 196 (27.7%) were PPI users. The majority of PPI users were males (80.6%), had an ECOG performance status of 0-1 (78.9%) and a nephrectomy (82.1%). Almost two-thirds of the patients had a favorable and intermediate IMDC risk category and 52% received nivolumab in the third line and beyond. PPI use did not correlate with PFS or OS (HR = 0.89, 95% CI 0.74-1.08 and HR = 1.24; 95% CI, 0.98-1.58, respectively). Grade 3-5 nivolumab-related adverse events were more common among PPI users (25.5% vs. 15.3%). CONCLUSIONS: This real-world study suggests that PPI use in patients with mRCC does not impact the efficacy outcomes but may influence the safety of nivolumab which warrants further investigations.

BACKGROUND: MBD4 mutations have been reported in uveal melanomas, acute myeloid leukemias, colorectal adenocarcinomas, gliomas, and spiradenocarcinomas and cause a hypermutated phenotype. Although metastatic uveal melanomas (mUM) are usually resistant to immune checkpoint inhibitors (ICI), the first reported MBD4-mutated (MBD4m) patient responded to ICI, suggesting that MBD4 mutation may predict response to ICI. METHODS: Retrospective cohort of mUM patients treated with ICI. MBD4 was sequenced in a subset of these patients. RESULTS: Three hundred mUM patients were included. Median follow-up was 17.3 months. Ten patients with an objective response and 20 cases with stable disease for >12 months were observed, corresponding to an objective response rate of 3.3% and a clinical benefit (i.e., responder patients and stable disease) rate of 10%. Of the 131 tumors sequenced for MBD4, five (3.8%) were mutated. MBD4 mutation was associated with a better objective response rate as three out of five MBD4m versus 4% of MBD4 wild-type patients responded (p < 0.001). Of these five responders, three presented progressive disease at 2.8, 13.9, and 22.3 months. Median PFS was 4.0 months in MBD4 wild-type and 22.3 months in MBD4m patients (HR = 0.22; p = 0.01). Median OS in MBD4def patients was unreached as compared to 16.6 months in MBD4pro (HR = 0.11; 95% CI: 0.02-0.86; log-rank p-test = 0.04; Fig. 2e). CONCLUSIONS: In mUM patients, MBD4 mutation is highly predictive for the response, PFS, and overall survival benefit to ICI. MBD4 could be a tissue-agnostic biomarker and should be sequenced in mUM, and other tumor types where MBD4 mutations are reported.

BACKGROUND: Renal Cell Carcinoma (RCC) is difficult to treat with 5-year survival rate of 10% in metastatic patients. Main reasons of therapy failure are lack of validated biomarkers and scarce knowledge of the biological processes occurring during RCC progression. Thus, the investigation of mechanisms regulating RCC progression is fundamental to improve RCC therapy. METHODS: In order to identify molecular markers and gene processes involved in the steps of RCC progression, we generated several cell lines of higher aggressiveness by serially passaging mouse renal cancer RENCA cells in mice and, concomitantly, performed functional genomics analysis of the cells. Multiple cell lines depicting the major steps of tumor progression (including primary tumor growth, survival in the blood circulation and metastatic spread) were generated and analyzed by large-scale transcriptome, genome and methylome analyses. Furthermore, we performed clinical correlations of our datasets. Finally we conducted a computational analysis for predicting the time to relapse based on our molecular data. RESULTS: Through in vivo passaging, RENCA cells showed increased aggressiveness by reducing mice survival, enhancing primary tumor growth and lung metastases formation. In addition, transcriptome and methylome analyses showed distinct clustering of the cell lines without genomic variation. Distinct signatures of tumor aggressiveness were revealed and validated in different patient cohorts. In particular, we identified SAA2 and CFB as soluble prognostic and predictive biomarkers of the therapeutic response. Machine learning and mathematical modeling confirmed the importance of CFB and SAA2 together, which had the highest impact on distant metastasis-free survival. From these data sets, a computational model predicting tumor progression and relapse was developed and validated. These results are of great translational significance. CONCLUSION: A combination of experimental and mathematical modeling was able to generate meaningful data for the prediction of the clinical evolution of RCC.

Primary tumour response may impact therapeutic strategies in metastatic renal cell carcinoma (mRCC) but remains unknown in the era of immune checkpoint inhibitors. We aimed to describe the response of the primary tumour in patients who did not undergo upfront cytoreductive nephrectomy (uCN) and were treated with nivolumab in the GETUG-AFU-26 NIVOREN phase 2 trial. Primary tumour response was prospectively assessed, as well as the overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). Among 720 patients, 111 did not undergo uCN, mainly patients with intermediate (45%) and poor (49%) International mRCC Database Consortium (IMDC) risk. In the 111 patients, nivolumab was used in the second line for 63% of patients and the third line or more for 37%, with an ORR of 16% (95% confidence interval [CI] 1025%); with a median follow-up of 24.5 mo (95% CI 21.6-27.1), median PFS was 2.7 mo (95% CI 2.5-4.0) and median OS was 15.9 mo (95% CI 9.5-19.8). A total of 67 patients had an evaluable primary renal lesion, four of whom (6%) experienced shrinkage of more than 30%. Overall, patients who did not undergo uCN had adverse baseline characteristics and nivolumab activity against the primary tumour was limited. PATIENT SUMMARY: In this report, we observed that nivolumab was associated with a limited response of the primary tumour in previously treated patients with metastatic kidney cancer.

Non-clear cell renal cell carcinomas (nccRCC) represent a highly heterogeneous group of kidney tumors, consisting of the following subtypes: papillary carcinomas, chromophobe renal cell carcinoma, so-called unclassified carcinomas or aggressive uncommon carcinomas such as Bellini carcinoma, renal cell carcinoma (RCC) with ALK rearrangement or fumarate hydratase-deficient RCC. Although non-clear cell cancers account for only 15 to 30% of renal tumors, they are often misclassified and accurate diagnosis continues to be an issue in clinical practice. Current therapeutic strategy of metastatic nccRCC is based primarily on guidelines established for clear cell tumors, the most common subtype, however this approach remains poorly defined. To date, published clinical trials for all histological nccRCC subtypes have been collectively characterized into one group, in contrast to clear cell RCC, and given the small numbers of cases, the interpretation of study results continues to be challenging. This review summarizes the available literature for each nccRCC subtype and highlights the lack of supportive evidence from prospective clinical trials and retrospective studies. Future trials should evaluate treatment approaches which focus on a specific histological subtype and progress in treating nccRCC will be contingent on understanding the unique biology of their individual histologies.

PURPOSE: Brain metastases (BM) usually represent a poor prognostic factor in solid tumors. About 10% of patients with renal cancer (RCC) will present BM. Local therapies such as stereotactic radiotherapy (SRT), whole brain radiotherapy (WBRT), and surgery are used to achieve brain control. We compared survival between patients with synchronous BM (SynBM group) and metachronous BM (MetaBM group). METHODS: It is a retrospective study of patients with clear cell renal cell carcinoma (ccRCC) and BM treated with TKI between 2005 and 2019 at the Centre Léon Bérard in Lyon. We collected prognostic factors: The International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk score, the TNM stage, the histological subtypes and the Fuhrman grade. Overall survival (OS) was defined from diagnosis of metastatic ccRCC to death. Brain progression-free survival (B-PFS) was defined from focal brain therapy to brain progression or death. RESULTS: 99 patients were analyzed, 44 in the SynBM group and 55 in the MetaBM group. OS in the MetaBM group was 49.4 months versus 19.6 months in the SynBM group, p = 0.0002. The median time from diagnosis of metastasic disease to apparition of BM in the MetaBM group was 22.9 months (4.3; 125.7). SRT was used for 101 lesions (66.4%), WBRT for 25 patients (16.4%), surgery for 21 lesions (13.8%), surgery followed by radiation for 5 lesions (3.3%). B-PFS for all patients was 7 months (IC95% [5.0-10.5]). CONCLUSIONS: Survival of patients with synchronous BM is inferior to that of patients with metachronous BM. Outcome is poor in both cases after diagnosis of BM. Brain screening should be encouraged at time of diagnosis of metastatis in ccRCC.
