RESUMEN
Background: Immune-checkpoint inhibitors (ICIs) have significantly improved metastatic renal cell carcinoma (mRCC) prognosis, although their efficacy in patients with bone metastases (BMs) remains poorly understood. We investigated the prognostic role of natremia in pretreated RCC patients with BMs receiving immunotherapy. Materials and methods: This retrospective multicenter study included RCC patients with BMs receiving nivolumab as second-line therapy or beyond. Inclusion criteria involved baseline sodium levels (pre-ICI) and sodium levels after 4 weeks of nivolumab initiation (post-ICI). The population was divided into two groups based on the median value, and response rates, progression-free survival (PFS), and overall survival (OS) were assessed. Results: Among 120 eligible patients, those with pre-treatment sodium levels ≥140 mEq/L showed longer OS (18.7 vs. 12.0 months, p=0.04). Pre-treatment sodium levels ≥140 mEq/L were associated with better OS compared to levels <140 mE/L (18.7 vs. 12.0, p=0.04). Post-treatment sodium levels ≥140 mEq/L were associated with improved PFS (9.6 vs. 3.2 months) and OS (25.1 vs. 8.8 months) (p=0.05 and p<0.01, respectively). Patients with consistent sodium levels ≥140 mEq/L at both time points exhibited the best outcomes compared to those with lower values (PFS 11.5 vs. 3.3 months and OS 42.2 vs. 9.0 months, respectively, p<0.01). Disease control rate was significantly higher in the latter group (p<0.01). Multivariate analysis confirmed the prognostic significance of sodium levels. Conclusion: Elevated sodium levels (≥140 mEq/L) pre- and post-ICI treatment correlate with better survival outcomes in mRCC patients with BMs. This finding suggests sodium level assessment as a potential prognostic factor in these patients and warrants further investigation, particularly in combination immunotherapy settings.

Upper tract urothelial carcinoma (UTUC) accounts for the 5-10% of all urothelial carcinomas (UCs). In this analysis, we reported the real-world data from the ARON-2 study (NCT05290038) on the efficacy of pembrolizumab in patients with UTUC who recurred or progressed after platinum-based chemotherapy. Medical records of patients with metastatic UTUC treated with pembrolizumab as second-line therapy were reviewed from 34 institutions in 14 countries. Patients were assessed for overall survival (OS), progression-free survival (PFS), and overall response rate (ORR). Univariate and multivariate analyses were used to explore the association of variables of interest with OS and PFS. 235 patients were included in our analysis. Median OS was 8.6 months (95% CI 6.6-12.1), the 1 year OS rate was 43% while the 2 years OS rate 29%. The median PFS was 5.1 months (95% CI 3.9-6.9); 46% of patients were alive at 6 months, 34% at 12 months and 25% at 24 months. According to RECIST 1.1, 18 patients (8%) experienced complete response (CR), 57 (24%) partial response (PR), 44 (19%) stable disease (SD), and 116 (49%) progressive disease (PD), with an ORR of 32%. Our study confirms the effectiveness of pembrolizumab in patients pretreated with a platinum-based combination, irrespective of their sensitivity to the first-line treatment and of their histology. In addition, we emphasized the limited benefit of the treatment with pembrolizumab in patients with hepatic metastases and poor ECOG performance status.
RESUMEN
Introduction: The Meet-URO 18 study is a multicentric study of patients with metastatic renal cell carcinoma receiving nivolumab in the second-line and beyond, categorized as responders (progression-free survival ≥ 12 months) and non-responders (progression-free survival < 3 months). Areas covered: The current study includes extensive immunohistochemical analysis of T-lineage markers (CD3, CD4, CD8, CD8/CD4 ratio), macrophages (CD68), ph-mTOR, CD15 and CD56 expression on tumor cells, and PD-L1 expression, on an increased sample size including 161 tumor samples (113 patients) compared with preliminary presented data. Responders' tumor tissue (n = 90; 55.9%) was associated with lower CD4 expression (p = 0.014), higher CD56 expression (p = 0.046) and higher CD8/CD4 ratio (p = 0.030). Expert opinion/commentary: The present work suggests the regulatory role of a subpopulation of T cells on antitumor response and identifies CD56 as a putative biomarker of immunotherapy efficacy.
RESUMEN
The treatment landscape for metastatic renal cell carcinoma (mRCC) has undergone significant transformations in recent years. The introduction of novel combination therapies involving tyrosine kinase inhibitors (TKI) and immune checkpoint inhibitors has resulted in improved oncological outcomes compared to traditional TKI monotherapy. In this evolving paradigm, the pivotal role of the multidisciplinary tumor board is underscored, particularly in shaping the therapeutic trajectory for patients eligible for locoregional interventions like cytoreductive nephrectomy and metastasectomy. In cases where systemic treatment is deemed appropriate, the absence of direct comparisons among the various combination therapies complicates the selection of a first-line approach. The clinician is faced with the challenge of making decisions based on patient-specific factors such as performance status, risk classification according to the International Metastatic Renal Cell Carcinoma Database Consortium, comorbidities, and disease characteristics, including the number and location of metastases and tumor histology. Considering these concerns, we propose, as a member of a Tuscany Interdisciplinary Uro-Oncologic Group, an algorithm to streamline the decision-making process for mRCC patients, offering guidance to clinicians in their day-to-day clinical practice.

The impact of tumor microenvironment (TME) in influencing clinical response to first-line immune checkpoint inhibitor (ICI)-based treatment in advanced renal cell carcinoma (RCC) is unclear. Immunohistochemistry (IHC) could identify biomarkers related to immune checkpoints and immune cell population. This study retrospectively characterized TME from 28 RCC patients who received first line ICI-based therapy through IHC assessment of selected markers and explored preliminary evidence about their possible correlation with treatment efficacy. We found a significantly higher count of CD80+, CD163+ cells and their ratio in RCC with clear cell component compared to those without clear cell features; additionally, patients with metastatic disease at diagnosis were associated with higher expression of CD163+ cells, while higher count of CD4+ cells and CD4+/CD8+ ratio were found in RCC with sarcomatoid features. Patients achieving partial or complete response were associated with lower expression of CD163+ cells (median 28 vs 47; p = 0.049). Furthermore, lower expression of CD163+ was associated with better PFS (median PFS 20.0 vs 4.7 months; HR 0.22 p = 0.011) and OS (median OS NR vs 14.4 months; HR 0.28 p = 0.036). A longer OS was reported in PD-L1 CPS negative patients (median OS NR vs 11.8 months; HR 0.20 p = 0.024). High infiltration of CD163+ macrophages, who typically present "anti-inflammatory" M2-like phenotype, could identify a subgroup of patients with poor survival after receiving first-line ICI.

Prostate carcinoma (PC), the second most diagnosed cancer globally, saw approximately 1,414,000 new cases in 2020, with 17% being de novo metastatic. In these cases, the 5-year relative survival rate is 32%. Metastatic hormone-sensitive prostate cancer (mHSPC) includes those with metastatic disease at initial diagnosis or after initial therapy without long-term androgen deprivation therapy (ADT), eventually progressing to castration-resistant prostate cancer (CRPC). The established therapeutic principle of ADT has persisted for 80 years, with luteinizing hormone-releasing hormone (LHRH) agonists like leuprorelin being commonly used. LHRH antagonists, such as degarelix, have also emerged. Recent advances in mHSPC treatment involve combination strategies with drugs proven effective in CRPC, considering prognostic factors like disease volume and presentation. This review outlines pivotal trials leading to drug approvals in mHSPC and proposes a treatment decision algorithm for the same, based on statement from the Tuscan Interdisciplinary Uro-Oncological Group. A multidisciplinary approach is crucial to tailor treatment intensity and weigh risks and benefits effectively.

BACKGROUND: Neutrophil-to-eosinophil ratio (NER) has been described to be associated with outcomes to immune checkpoint inhibitors (ICI) in several tumor types, but less is known about its role of in the response to avelumab in advanced urothelial cancer (aUC). Thus, we reported outcomes by NER of aUC patients treated with avelumab as maintenance after initial response to platinum-based chemotherapy and enrolled in the Maintenance with AVeLumAb ([MALVA] in advanced urothelial neoplasms in response to first-line chemotherapy: an observational retrospective study) study (Meet-URO 25). PATIENTS AND METHODS: Median NER at baseline and after 3 cycles of avelumab were calculated. Progression-free survival (PFS) and overall survival (OS) by NER were reported. RESULTS: At the cutoff date (April 15, 2023), a total of 109 patients were included. The median NER was 28.05 at baseline and 24.46 after 3 cycles of avelumab, respectively. Median PFS was not reached for patients with baseline NER less than the median (Asunto(s)

RESUMEN
BACKGROUND: Immune checkpoint inhibitors have changed previous treatment paradigm of advanced urothelial carcinoma (UC). The ARON-2 study (NCT05290038) aimed to assess the real-world effectiveness of pembrolizumab in patients recurred or progressed after platinum-based chemotherapy. PATIENTS AND METHODS: Medical records of patients with documented metastatic UC treated by pembrolizumab as second-line therapy were retrospectively collected from 88 institutions in 23 countries. Patients were assessed for overall survival (OS), progression-free survival (PFS) and overall response rate (ORR). Cox proportional hazards models were adopted to explore the presence of prognostic factors. RESULTS: In total, 836 patients were included: 544 patients (65%) received pembrolizumab after progression to first-line platinum-based chemotherapy in the metastatic setting (cohort A) and 292 (35%) after recurring within < 12 months since the completion of adjuvant or neoadjuvant chemotherapy (cohort B). The median follow-up time was 15.3 months. The median OS and the ORR were 10.5 months and 31% in the overall study population, 9.1 months and 29% in cohort A and 14.6 months and 37% in cohort B. At multivariate analysis, ECOG-PS ≥ 2, bone metastases, liver metastases and pembrolizumab setting (cohort A vs B) proved to be significantly associated with worst OS and PFS. Stratified by the presence of 0, 1-2 or 3-4 prognostic factors, the median OS was 29.4, 12.5 and 4.1 months (p < 0.001), while the median PFS was 12.2, 6.4 and 2.8 months, respectively (p < 0.001). CONCLUSIONS: Our study confirms that pembrolizumab is effective in the advanced UC real-world context, showing outcome differences between patients recurred or progressed after platinum-based chemotherapy.

RESUMEN
BACKGROUND: Peritoneal metastases (PM) have been reported in approximately 1% of patients with metastatic Renal Cell Carcinoma (mRCC). Outcome data are limited due to the rarity of this metastatic site. Therefore, the aim of our study is to describe renal cell carcinoma (RCC) patients with PM treated as per clinical practice. MATERIALS AND METHODS: Baseline characteristics and outcome data of patients with PM from RCC were retrospectively collected from 18 Italian oncological referral centers adhering to the Meet-Uro group, from January 2016 to January 2023. RESULTS: We collect 81 RCC patients with PM. 78/81 received systemic treatment, 3/81 only best supportive care. First line treatment included tyrosine-kinase inhibitors (TKI) (46/78), ImmuneOncology (IO)-TKI (26/78) and IO-IO (6/78), with different Objective Response Rate (ORR) (43.4% in TKI monotherapy group vs 50% in IO-TKI group, respectively) and Disease Control Rate (DCR) (60.8% in TKI treated patients vs. 76.9% in IO-TKI treated patients). Median PFS was 6.4 months (95%CI 4.18-14.8) in patients treated with TKI monotherapy vs 23.7 months (95%CI 11.1-NR) in patients treated with IO-TKI (p < 0.015). The median OS (mOS) was 22.7 months (95%CI 13.32 - 64.7) in the TKI monotherapy group vs 34.5 mo (95%CI NR-NR) in the IO-TKI group with 53.8% of patients alive at 1 years in the latter group, (p < 0.16). Primary refractory patients were 36.9% for TKI and 15.3% for IO-TKI. According to International Metastatic renal cell carcinoma Database Consortium (IMDC) score, mPFS and mOS were consistent among risk categories. Median PFS was 36.6 months (95%CI 10.9-NR) for good risk patients compared to 10 months (95%CI 7.5-29.8) for intermediate risk and 2.96 months (95%CI 2.43-11.28) for poor risk population (p < 0.0005) whereas mOS was NR (95%CI 28.65-NR) for good risk patients compared to 35.3 months (95%CI 24.6-NA) and 12.4 months (95%CI 3.52-NR) for intermediate and poor risk population, respectively, (p < 0.0002). Only 34/78 (43.5%) received a second line treatment that was TKI (ORR 8.3% and DCR 41.6%) or IO (ORR 18.1% and DCR 40.9%). CONCLUSION: We report one of the largest case series regarding PM from RCC. Characteristics of patients suggest a more aggressive behavior of PM from mRCC. Outcome data suggest that TKI-IO as first line treatment, and TKI as second line, confirm their activity for these patients with dismal prognosis.

BACKGROUND AND OBJECTIVE: In comparison to chemotherapy, enfortumab vedotin (EV) prolonged overall survival in patients with previously treated advanced urothelial carcinoma in EV-301. The objective of the present study was to assess patient experiences of EV versus chemotherapy using patient-reported outcome (PRO) analysis of health-related quality of life (HRQoL). METHODS: For patients in the phase 3 EV-301 trial randomized to EV or chemotherapy we assessed responses to the validated European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (QLQ-C30) at baseline, weekly for the first 12 wk, and then every 12 wk until discontinuation. We analyzed the QLQ-C30 change from baseline to week 12, the confirmed improvement rate, and the time to improvement or deterioration. KEY FINDINGS AND LIMITATIONS: Baseline PRO compliance rates were 91% for the EV arm (n = 301) and 89% for the chemotherapy arm (n = 307); the corresponding average rates from baseline to week 12 were 70% and 67%. Patients receiving EV versus chemotherapy had reduced pain (difference in change from baseline to week 12: -5.7, 95% confidence interval [CI] -10.8 to -0.7; p = 0.027) and worsening appetite loss (7.3, 95% CI 0.90-13.69; p = 0.026). Larger proportions of patients in the EV arm reported HRQoL improvement from baseline than in the chemotherapy arm; the odds of a confirmed improvement across ten QLQ-C30 function/symptom scales were 1.67 to 2.76 times higher for EV than for chemotherapy. Patients in the EV arm had a shorter time to first confirmed improvement in global health status (GHS)/QoL, fatigue, pain, and physical, role, emotional, and social functioning (all p < 0.05). EV delayed the time to first confirmed deterioration in GHS/QoL (p = 0.027), but worsening appetite loss occurred earlier (p = 0.009) in comparison to chemotherapy. CONCLUSIONS AND CLINICAL IMPLICATIONS: HRQoL with EV was maintained, and deterioration in HRQoL was delayed with EV in comparison to chemotherapy. Better results with EV were reported for some scales, with the greatest difference observed for pain. These findings reinforce the EV safety and efficacy outcomes and benefits observed in EV-301. PATIENT SUMMARY: Patients with previously treated advanced cancer of the urinary tract receiving the drug enfortumab vedotin maintained their HRQoL in comparison to patients treated with chemotherapy. The EV-301 trial is registered on ClinicalTrials.gov as NCT03474107 and on EudraCT as 2017-003344-21.

BACKGROUND: Currently, several therapies are available for metastatic castration-resistant prostate cancer (mCRPC) but no specific clinical factors to personalize treatment. We first sought the prognostic value of duration on androgen-deprivation therapy (ADT) for hormone-sensitive prostate cancer (HSPC) in patients receiving androgen-receptor-signaling inhibitors (ARSI) for mCRPC. METHODS: A multicenter cohort of mCRPC patients who started ARSI between July 2011 and October 2021 was identified. Based on their initial disease burden and duration on ADT for HSPC, primary progressive (PP) men were classified into four groups: low/intermediate-risk localized disease (LOC) and high-risk localized/locally advanced disease (LAD) and short-term (ST) < 24 vs. long-term (LT) ADT ≥ 24 months, whereas de novo (DN) mHSPC were subdivided into short-time vs. long-time to CRPC. RESULTS: We included 919 mCRPC patients with a median age of 77 years [interquartile range (IQR) = 71-82)]. Median ADT duration in HSPC was 24 months (IQR = 14-40). Median follow-up was 91 months (IQR = 62-138), median OS and PFS from ARSI start were 20 (IQR 10-32) and 10 months (IQR = 5-19), respectively. In PP developing metastatic disease (n = 655, 71.3%), LOC and LAD with ST ADT had a greater than almost double-risk of death compared to LT ADT (LOC/ST: hazard ratio [HR] = 2.01; 95% CI 1.54-2.64; LAD/ST: HR = 1.73; 95% CI 1.34-2.24; p < 0.001). In the multivariate analysis including age, prognostic cohort, Gleason, ECOG, radical radiotherapy and prostatectomy, groups with ST ADT were associated with worse OS compared to LT ADT (LOC/ST: HR = 1.84; 95% CI 1.38-2.45; p < 0.001; LAD/ST: HR = 1.59; 95% CI 1.21-2.10; p < 0.001), along with ECOG > 2 (HR = 1.55; 95% CI 1.06-2.26; p = 0.03). There were also similar results of PFS. Moreover, long-time to CRPC in patients with history of DN mHSPC (n = 264, 28.7%) resulted in a better OS/PFS (HR = 0.76, 95% CI 0.56-1.02, p = 0.064 and HR = 0.74, 95% CI 0.55-0.99, p = 0.042, respectively). CONCLUSIONS: Our study showed that duration on ADT for mHSPC was significantly associated with survival in mCRPC undergoing ARSI. These findings suggest a possible connection between initial management of prostate tumour and a better prognostication in mCRPC. Prospective trials are warranted.
RESUMEN
Background: Immunotherapies exhibit peculiar cancer response patterns in contrast to chemotherapy and targeted therapy. Some patients experience disease response after initial progression or durable responses after treatment interruption. In clinical practice, immune checkpoint inhibitors may be continued after radiological progression if clinical benefit is observed. As a result, estimating progression-free survival (PFS) based on the first disease progression may not accurately reflect the actual benefit of immunotherapy. Methods: The Meet-URO 15 study was a multicenter retrospective analysis of 571 pretreated metastatic renal cell carcinoma (mRCC) patients receiving nivolumab. Time to strategy failure (TSF) was defined as the interval from the start of immunotherapy to definitive disease progression or death. This post-hoc analysis compared TSF to PFS and assess the response and survival outcomes between patients treatated beyond progression (TBP) and non-TBP. Moreover, we evaluated the prognostic accuracy of the Meet-URO score versus the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) score based on TSF and PFS. Results: Overall, 571 mRCC patients were included in the analysis. Median TSF was 8.6 months (95% CI: 7.0 - 10.1), while mPFS was 7.0 months (95% CI: 5.7 - 8.5). TBP patients (N = 93) had significantly longer TSF (16.3 vs 5.5 months; p < 0.001) and overall survival (OS) (34.8 vs 17.9 months; p < 0.001) but similar PFS compared to non-TBP patients. In TBP patients, a median delay of 9.6 months (range: 6.7-16.3) from the first to the definitive disease progression was observed, whereas non-TBP patients had overlapped median TSF and PFS (5.5 months). Moreover, TBP patients had a trend toward a higher overall response rate (33.3% vs 24.3%; p = 0.075) and disease control rate (61.3% vs 55.5%; p = 0.31). Finally, in the whole population the Meet-URO score outperformed the IMDC score in predicting both TSF (c-index: 0.63 vs 0.59) and PFS (0.62 vs 0.59). Conclusion: We found a 2-month difference between mTSF and mPFS in mRCC patients receiving nivolumab. However, TBP patients had better outcomes, including significantly longer TSF and OS than non-TBP patients. The Meet-URO score is a reliable predictor of TSF and PFS.
RESUMEN
BACKGROUND: Although in metastatic renal cell carcinoma (mRCC) patients with intermediate and poor risk the benefit of combination strategies versus tyrosine kinase inhibitor (TKI) has been ascertained, in those with favorable risk data are ambiguous. Herein, we investigated the impact of number and type of metastatic site in patients with favorable risk to contribute to the best therapeutic choice. MATERIAL AND METHODS: Multicenter data regarding patients with favorable risk mRCC carcinoma receiving first-line TKIs, sunitinib or pazopanib, were retrospectively collected. We divided our population into 2 groups based on the number of metastatic sites and analyzed its impact on tumor response and efficacy outcome. The Kaplan-Meier method was used to estimate efficacy outcomes and the log-rank test to examine differences between subgroups. RESULTS: A total of 107 patients with a median age of 69 years were included in the final analysis. Patients with 1 metastatic site, compared with patients with > 1 site, had a significantly longer overall survival (OS) (not reached vs. 66 months) and a trend, although not statistically significant, of better progression-free survival (PFS) (31 vs. 17 months). In patients with 1 metastatic site, liver involvement was correlated with worse PFS and OS at the univariate analysis (P = .01) and was confirmed as independent poor prognostic factor for PFS at multivariate analysis. CONCLUSION: In conclusion, we reported a longer OS in favorable risk mRCC patients receiving TKI with only 1 metastatic site. Nevertheless, in patients with a single metastatic site, hepatic involvement correlated with worse PFS compared to other metastatic sites.

BACKGROUND: Renal c carcinoma (RCC) is one of the most common urinary cancers worldwide, with a predicted increase in incidence in the coming years. Immunotherapy, as a single agent, in doublets, or in combination with anti-vascular endothelial growth factor receptor tyrosine kinase inhibitors (TKIs), has rapidly become a cornerstone of the RCC therapeutic scenario, but no head-to-head comparisons have been made. In this setting, real-world evidence emerges as a cornerstone to guide clinical decisions. OBJECTIVE: The objective of this retrospective study was to assess the outcome of patients treated with first-line immune combinations or immune oncology (IO)-TKIs for advanced RCC. DESIGN, SETTING, AND PARTICIPANTS: Data from 930 patients, 654 intermediate risk and 276 poor risk, were collected retrospectively from 58 centers in 20 countries. Special data such as sarcomatoid differentiation, body mass index, prior nephrectomy, and metastatic localization, in addition to biochemical data such as hemoglobin, platelets, calcium, lactate dehydrogenase, neutrophils, and radiological response by investigator's criteria, were collected. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method. The median follow-up was calculated by the inverse Kaplan-Meier method. RESULTS AND LIMITATIONS: The median follow-up time was 18.7 mo. In the 654 intermediate-risk patients, the median OS and PFS were significantly longer in patients with the intermediate than in those with the poor International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) criteria (38.9 vs 17.3 mo, 95% confidence interval [CI] p < 0.001, and 17.3 vs 11.6 mo, 95% CI p < 0.001, respectively). In the intermediate-risk subgroup, the OS was 55.7 mo (95% CI 31.4-55.7) and 40.2 mo (95% CI 29.6-51.6) in patients treated with IO + TKI and IO + IO combinations, respectively (p = 0.047). PFS was 30.7 mo (95% CI 16.5-55.7) and 13.2 mo (95% CI 29.6-51.6) in intermediate-risk patients treated with IO + TKI and IO + IO combinations, respectively (p < 0.001). In the poor-risk subgroup, the median OS and PFS did not show a statistically significant difference between IO + IO and IO + TKI. Our study presents several limitations, mainly due to its retrospective nature. CONCLUSIONS: Our results showed differences between the IO + TKI and IO + IO combinations in intermediate-risk patients. A clear association with longer PFS and OS in favor of patients who received the IO + TKI combinations compared with the IO-IO combination was observed. Instead, in the poor-risk group, we observed no significant difference in PFS or OS between patients who received different combinations. PATIENT SUMMARY: Renal cancer is one of the most frequent genitourinary tumors. Treatment is currently based on immunotherapy combinations or immunotherapy with tyrosine kinase inhibitors, but there are no comparisons between these.In this study, we have analyzed the clinical course of 930 patients from 58 centers in 20 countries around the world. We aimed to analyze the differences between the two main treatment strategies, combination of two immunotherapies versus immunotherapy + antiangiogenic therapy, and found in real-life data that intermediate-risk patients (approximately 60% of patients with metastatic renal cancer) seem to benefit more from the combination of immunotherapy + antiangiogenic therapy than from double immunotherapy. No such differences were found in poor-risk patients. This may have important implications in daily practice decision-making for these patients.

Importance: Low sodium levels have been associated with negative outcomes among patients with metastatic renal cell carcinoma (mRCC) receiving therapies other than immune checkpoint inhibitors (ICIs). Objective: To investigate the role of natremia in patients with mRCC receiving nivolumab as a second-line or subsequent therapy. Design, Setting, and Participants: In this retrospective cohort study, the clinical and biochemical data of patients with mRCC receiving nivolumab were collected from October 2015 to November 2019 as part of a multicenter Italian study. Data analysis was performed from February to March 2023. Exposure: Nivolumab was administered intravenously at a dose of 3 mg/kg every 2 weeks and, since May 2018, at a fixed dose of 240 mg every 2 weeks or 480 mg every 4 weeks. Patients were divided into 2 groups according to their median serum sodium value (<140 or ≥140 mEq/L). Main Outcomes and Measures: The primary outcomes were the associations of pre-ICI and post-ICI sodium levels with overall survival (OS), progression-free survival (PFS), objective response rate, and disease control rate (DCR). The Kaplan-Meier method was used to estimate PFS and OS, and differences between groups were compared using the log-rank test. Results: A total of 401 patients with mRCC receiving nivolumab as second-line therapy were evaluated, and 355 eligible patients (median [range] age, 76 [44-84] years; 258 male patients [72.7%]) were included in the final cohort. Among patients with pre-ICI sodium greater than or equal to 140 mEq/L compared with those with sodium less than 140 mEq/L, the median PFS was 9.3 months (95% CI, 6.5-11.5 months) vs 7.4 months (95% CI, 4.6-10.1 months; P = .90), and the median OS was 29.2 months (95% CI, 21.8-35.9 months) vs 20.0 months (95% CI, 14.1-26.8 months; P = .03). Patients with post-ICI sodium values greater than or equal to 140 mEq/L had longer PFS (11.1 months [95% CI, 8.5-1.5 months] vs 5.1 months [95% CI, 4.1-7.5 months]; P = .01) and OS (32.9 months [95% CI, 25.1-42.6 months] vs 17.1 months [95% CI, 12.6-24.5 months]; P = .006) compared with patients with sodium values less than 140 mEq/L. Patients with both pre-ICI and post-ICI sodium values greater than or equal to 140 mEq/L exhibited a significant improvement in clinical outcomes compared with those with a value less than 140 mEq/L (PFS, 11.5 months [95% CI, 8.8-16.4 months] vs 5.8 months [95% CI, 4.4-8.3 months]; P = .008); OS, 37.6 months [95% CI, 29.0-49.9 months] vs 19.4 months [95% CI, 14.1-24.5 months]; P = .01). Moreover, sodium levels greater than or equal to 140 mEq/L were associated with significantly better DCR than lower sodium levels. Conclusions and Relevance: In this retrospective cohort study of patients with mRCC receiving nivolumab, sodium values greater than or equal to 140 mEq/L, both before and/or after ICI, were associated with better OS and PFS, as well as a higher DCR, compared with levels less than 140 mEq/L. These findings suggest that sodium levels may be associated with survival outcomes in patients with mRCC and may have potential use as variables to consider in patients' risk scores.

Background/Aim: We performed a multicenter retrospective observational study to investigate the impact of immune checkpoint inhibitors (ICIs) on the survival of patients with bone metastases (BMs) from renal cell cancer (RCC). Patients and Methods: A total of 98 patients with metastatic RCC (mRCC) treated with ICIs were retrospectively enrolled. All patients received standard treatments with nivolumab alone or in combination with ipilimumab from December 2015 to March 2022. The primary endpoint was median overall survival (OS). Results: Forty-three patients (44%) had radiological evidence of BMs. No statistically significant difference in OS was reported between the BM population and the entire population (p=0.254). Conclusion: Our study suggests some degree of ICI activity to treat patients with BMs from RCC, historically associated with a poorer prognosis.
RESUMEN
BACKGROUND: Concomitant medications may potentially affect the outcome of cancer patients. In this sub-analysis of the ARON-2 real-world study (NCT05290038), we aimed to assess the impact of concomitant use of proton pump inhibitors (PPI), statins, or metformin on outcome of patients with metastatic urothelial cancer (mUC) receiving second-line pembrolizumab. METHODS: We collected data from the hospital medical records of patients with mUC treated with pembrolizumab as second-line therapy at 87 institutions from 22 countries. Patients were assessed for overall survival (OS), progression-free survival (PFS), and overall response rate. We carried out a survival analysis by a Cox regression model. RESULTS: A total of 802 patients were eligible for this retrospective study; the median follow-up time was 15.3 months. PPI users compared to non-users showed inferior PFS (4.5 vs. 7.2 months, p = 0.002) and OS (8.7 vs. 14.1 months, p < 0.001). Concomitant PPI use remained a significant predictor of PFS and OS after multivariate Cox analysis. The use of statins or metformin was not associated with response or survival. CONCLUSIONS: Our study results suggest a significant prognostic impact of concomitant PPI use in mUC patients receiving pembrolizumab in the real-world context. The mechanism of this interaction warrants further elucidation.

BACKGROUND: The upfront treatment of metastatic renal cell carcinoma (mRCC) has been revolutionized by the introduction of immune-based combinations. The role of cytoreductive nephrectomy (CN) in these patients is still debated. The ARON-1 study (NCT05287464) was designed to globally analyze real-world data of mRCC patients receiving first-line immuno-oncology combinations. This sub-analysis is focused on the role of upfront or delayed partial or radical CN in three geographical areas (Western Europe, Eastern Europe, America/Asia). METHODS: We conducted a multicenter retrospective observational study in mRCC patients treated with first-line immune combinations from 55 centers in 19 countries. From 1152 patients in the ARON-1 dataset, we selected 651 patients with de novo mRCC. 255 patients (39%) had undergone CN, partial in 14% and radical in 86% of cases; 396 patients (61%) received first-line immune-combinations without previous nephrectomy. RESULTS: Median overall survival (OS) from the diagnosis of de novo mRCC was 41.6 months and not reached (NR) in the CN subgroup and 24.0 months in the no CN subgroup, respectively (P<0.001). Median OS from the start of first-line therapy was NR in patients who underwent CN and 22.4 months in the no CN subgroup (P<0.001). Patients who underwent CN reported longer OS compared to no CN in all the three geographical areas. CONCLUSIONS: No significant differences in terms of patients' outcome seem to clearly emerge, even if the rate CN and the choice of the type of first-line immune-based combination varies across the different Cancer Centers participating in the ARON-1 project.

BACKGROUND: Immuno-oncology combinations have achieved survival benefits in patients with metastatic renal cell carcinoma (mRCC). OBJECTIVE: The ARON-1 study (NCT05287464) was designed to globally collect real-world data on the use of immuno-combinations as first-line therapy for mRCC patients. PATIENTS AND METHODS: Patients aged ≥ 18 years with a cytologically and/or histologically confirmed diagnosis of mRCC treated with first-line immuno-combination therapies were retrospectively included from 47 International Institutions from 16 countries. Patients were assessed for overall survival (OS), progression-free survival (PFS), and overall clinical benefit (OCB). RESULTS: A total of 729 patients were included; tumor histology was clear-cell RCC in 86% of cases; 313 patients received dual immuno-oncology (IO + IO) therapy while 416 were treated with IO-tyrosine kinase inhibitor (IO + TKI) combinations. In the overall study population, the median OS and PFS were 36.5 and 15.0 months, respectively. The median OS was longer with IO+TKI compared with IO+IO therapy in the 616 patients with intermediate/poor International mRCC Database Consortium (IMDC) risk criteria (55.7 vs 29.7 months; p = 0.045). OCB was 84% for IO+TKI and 72% for IO + IO combination (p < 0.001). CONCLUSIONS: Our study may suggest that immuno-oncology combinations are effective as first-line therapy in the mRCC real-world context, showing outcome differences between IO + IO and IO + TKI combinations in mRCC subpopulations.
