Although immune checkpoint inhibitors (ICI) and/or tyrosine kinase inhibitors (TKI) are the standard treatment of advanced unresectable or metastatic renal cell carcinoma (RCC), the impact of concomitant medications remains unclear. We aimed to evaluate the impact of concomitant medications on survival outcomes in patients treated with systemic therapy for advanced unresectable or metastatic RCC. In August 2024, PubMed, Scopus, and Web of Science were queried for studies evaluating concomitant medications in patients with advanced unresectable or metastatic RCC (PROSPERO: CRD42024573252). The primary outcome was overall survival (OS). A fixed- or random-effects model was used for meta-analysis according to heterogeneity. We identified 22 eligible studies (5 prospective and 17 retrospective) comprising 16,072 patients. Concomitant medications included proton pump inhibitors (PPI) (n = 3959), antibiotics (n = 571), statins (n = 5466), renin-angiotensin system inhibitors (RASi) (n = 6615), and beta-blockers (n = 1964). Both concomitant PPI and antibiotics were significantly associated with worse OS in patients treated with ICI (PPI: HR: 1.22, P = .01, and antibiotics: HR: 2.09, P < .001). Concomitant statins, RASi, or beta-blocker were significantly associated with improved OS in patients treated with TKI (statins: HR: 0.81, P = .03, RASi: HR: 0.63, P < .001, beta-blocker: HR: 0.69, P < .001, respectively). In patients treated with ICI, RASi was significantly associated with improved OS (HR: 0.64, P = .02). Concomitant use of antibiotics or PPI with ICI can reduce its oncologic efficacy. Conversely, concomitant statins, RASi, or beta-blockers can enhance the oncologic efficacy of TKI. When initiating systemic therapy for metastatic RCC, it may be important for clinicians to assess baseline co-medications and recognize their possible positive or negative effects.

BACKGROUND AND OBJECTIVE: Adjuvant pembrolizumab significantly improved overall survival (OS) in renal cell carcinoma (RCC), but real-world data on sequential treatment are scarce. We sought to evaluate the clinical outcomes of first-line (1L) systemic therapy following adjuvant immune oncology (IO)-based regimens. METHODS: A retrospective study including patients with recurrent RCC following adjuvant IO across 29 international institutions was conducted. The primary endpoint was progression-free survival (PFS) on 1L systemic therapy estimated using the Kaplan-Meier method. Preplanned subanalyses of clinical outcomes by type of 1L systemic therapy, recurrence timing, and International Metastatic RCC Database Consortium (IMDC) risk groups were performed. Treatment-related adverse events leading to treatment discontinuation, dose reduction, or corticosteroid use were assessed. KEY FINDINGS AND LIMITATIONS: A total of 94 patients were included. Most received adjuvant pembrolizumab (n = 37, 39%), atezolizumab (n = 28, 30%), or nivolumab + ipilimumab (n = 15, 16%). The cohort included 49 (52%) patients who had recurrence within 3 mo of the last adjuvant IO dose, whereas 45 (48%) recurred beyond 3 mo. Bone metastases were significantly higher in tumors recurring at <3 mo (10/49, 20%) than those recurring at >3 mo (1/45, 2.2%; p = 0.008). Most patients received 1L vascular endothelial growth factor-targeted therapy (VEGF-TT; n = 37, 39%), IO + VEGF-TT (n = 26, 28%), or IO + IO (n = 12, 13%). The remaining underwent local therapy. The median follow-up for the 1L systemic therapy cohort was 15 mo. The 18-mo PFS and OS rates were 45% (95% confidence interval [CI]: 34-60) and 85% (95% CI: 75-95), respectively. Treatment-related adverse events occurred in 32 (42%) patients and included skin toxicity (n = 7, 9.2%), fatigue (n = 6, 7.9%), and diarrhea/colitis (n = 4, 5.3%). Limitations included selecting patients from large academic centers and the short follow-up period. CONCLUSIONS AND CLINICAL IMPLICATIONS: A subset of patients with recurrent RCC following adjuvant IO respond to systemic therapies, including VEGF-TT and IO-based regimens. Notably, patients with favorable-risk disease may derive more benefit from VEGF-TT than from IO therapies in this setting. Future approaches utilizing radiographic tools and biomarker-based liquid biopsies are warranted to detect occult metastatic disease and identify candidate patients for adjuvant IO therapy. PATIENT SUMMARY: Adjuvant pembrolizumab significantly improved overall survival in renal cell carcinoma (RCC). There are limited data on clinical outcomes after the recurrence of RCC tumors following adjuvant immunotherapy. In this study, we find that patients respond to subsequent systemic therapies across different treatment options.

OBJECTIVE: To compare the differential efficacy of first-line immune checkpoint inhibitor (ICI)-based combined therapies among patients with intermediate- and poor-risk metastatic renal cell carcinoma (mRCC), as recently, the efficacy of triplet therapy comprising nivolumab plus ipilimumab plus cabozantinib has been published. PATIENTS AND METHODS: Three databases were searched in December 2022 for randomised controlled trials (RCTs) analysing oncological outcomes in patients with mRCC treated with first-line ICI-based combined therapies. We performed network meta-analysis (NMA) to compare the outcomes, including progression-free survival (PFS) and objective response rates (ORRs), in patients with intermediate- and poor-risk mRCC; we also assessed treatment-related adverse events. RESULTS: Overall, seven RCTs were included in the meta-analyses and NMAs. Treatment ranking analysis revealed that pembrolizumab + lenvatinib (99%) had the highest likelihood of improved PFS, followed by nivolumab + cabozantinib (79%), and nivolumab + ipilimumab + cabozantinib (77%). Notably, compared to nivolumab + cabozantinib, adding ipilimumab to nivolumab + cabozantinib did not improve PFS (hazard ratio 1.02, 95% confidence interval 0.72-1.43). Regarding ORRs, treatment ranking analysis also revealed that pembrolizumab + lenvatinib had the highest likelihood of providing better ORRs (99.7%). The likelihoods of improved PFS and ORRs of pembrolizumab + lenvatinib were true in both International Metastatic RCC Database Consortium (IMDC) risk groups. CONCLUSIONS: Our analyses confirmed the robust efficacy of pembrolizumab + lenvatinib as first-line treatment for patients with intermediate or poor IMDC risk mRCC. Triplet therapy did not result in superior efficacy. Considering both toxicity and the lack of mature overall survival data, triplet therapy should only be considered in selected patients.

Východiska: Kabozantinib je inhibitor tyrozinkinázy (tyrosin kinase inhibitor – TKI) proti receptoru pro vaskulární růstový faktor (VEGFR), podobně i MET a AXL. V klinické studii METEOR prokázal u pacientů s metastatickým renálním karcinomem (mRCC) účinnost ve srovnání s everolimem po předchozí léčbě TKI. Cíl: Stanovení účinnosti a tolerance kabozantinibu ve druhé nebo vyšší linii léčby mRCC po předchozí léčbě inhibitory tyrozinkinázy. Pacienti a metody: Celkem bylo hodnoceno 45 pacientů s mRCC léčených ve dvou onkologických centrech (Krajská nemocnice Liberec, Fakultní nemocnice Motol) v klinické praxi. Stanovili jsme přežití bez známek progrese (progression-free survival – PFS) a celkové přežití (overall survival – OS) pomocí Kaplan-Meierovy analýzy a vliv faktorů na léčebné výsledky pomocí regresní analýzy. Statistické zhodnocení bylo provedeno na hladině významnosti α = 0,05. Výsledky: Medián sledování byl 24 měsíců. Medián PFS činil 8,7 měsíce (95% CI 6,7–19,5), medián OS činil 21,6 měsíce (95% CI 13,2–nedosaženo). Parciální remise byla pozorována u 42,5 %, stabilizace onemocnění u 37,8 % pacientů. Primární progrese byla zjištěna u 20 % nemocných. V regresní analýze jsme prokázali prognostický příznivý vliv na prodloužení PFS u pacientů ve vyšším věku a s delším trváním první linie terapie. Regresní analýza dále prokázala příznivý vliv na prodloužení OS u pacientů v lepším celkovém stavu, při delším trvání léčby první linie a u pacientů, u kterých byla po selhání kabozantinibu indikována imunoterapie. Toxicita stupně 3–4 byla pozorována u 37,8 % pacientů, dominoval průjem. Závěr: Naše společná analýza potvrdila účinnost a toleranci kabozantinibu v léčbě druhé a vyšší linie mRCC.
Background: Cabozantinib is a tyrosine kinase inhibitor (TKI) that targets vascular endothelial growth factor receptor (VEGFR) as well as MET and AXL. In METEOR study, cabozantinib demonstrated efficacy when compared with everolimus in pacients with metastatic renal cell cancer (mRCC) after previous TKI therapy. Purpose: The determination of efficacy and tolerance of cabozantinib in the second or higher lines of the therapy of mRCC after previous treatment with tyrosinkinase inhibitors. Patients and methods: A total of 45 patients with mRCC were treated in two oncology centers (Regional Hospital Liberec and University Hospital Motol, Prague) in clinical practice. We determined progression free survival (PFS) and overall survival (OS) according to Kaplan-Meier analysis. We performed a multivariate analysis of the risk factors for treatment outcomes (PFS, OS) by Cox regression analysis. All statistics were evaluated at the significance level of α = 0.05. Results: A median of follow-up was 24 months. Median PFS was 8.7 months (95% CI 6.7–19.5), median OS was 21.6 months (95% CI 13.2–not achieved). Parcial remission was described in 42.5% patients, stabilization in 37.8% patients. Progression as the best response was demonstrated in 20% of patients. Regression analysis demonstrated a statistically significant favorable prognostic effect on PFS in patients at older age and patients with longer first-line therapy. The regression analysis demonstrated a statistically significant favorable prognostic effect on OS in patients with Eastern Cooperative Oncology Group (ECOG) performance status 0, patients with longer-first line therapy and patients treated with immunotherapy in the next lines. Grade 3–4 toxicity was described in 37.8% patients. The most common type of toxicity was hypertension. Conclusion: Our analysis demonstrated the efficacy and good tolerance of cabozantinib in with mRCC treated by cabozantinib in second-line therapy.
Immunotherapy combinations with tyrosine-kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) had significantly improved outcomes of patients with mRCC. Predictive and prognostic factors are crucial to improve patients' counseling and management. The present study aimed to externally validate the prognostic value of a previously developed red cell-based score, including hemoglobin (Hb), mean corpuscular volume (MCV) and red cell distribution width (RDW), in patients with mRCC treated with first-line immunotherapy combinations (TKI plus ICI or ICI plus ICI). We performed a sub-analysis of a multicentre retrospective observational study (ARON-1 project) involving patients with mRCC treated with first-line immunotherapy combinations. Uni- and multivariable Cox regression models were used to assess the correlation between the red cell-based score and progression-free survival (PFS), and overall survival (OS). Logistic regression were used to estimate the correlation between the score and the objective response rate (ORR). The prognostic impact of the red cell-based score on PFS and OS was confirmed in the whole population regardless of the immunotherapy combination used [median PFS (mPFS): 17.4 vs 8.2 months, HR 0.66, 95% CI 0.47-0.94; median OS (mOS): 42.0 vs 17.3 months, HR 0.60, 95% CI 0.39-0.92; p < 0.001 for both]. We validated the prognostic significance of the red cell-based score in patients with mRCC treated with first-line immunotherapy combinations. The score is easy to use in daily clinical practice and it might improve patient counselling.
PURPOSE: Four recent first-line clinical trials leveraging immune-oncology agents demonstrated an overall survival (OS) benefit relative to sunitinib. We aimed to provide formal comparisons among immune-oncology combinations in terms of OS, progression-free survival (PFS), objective response rates and treatment-related adverse events (AEs). MATERIALS AND METHODS: PubMed® database was searched for studies indexed from January 1, 2016 through March 6, 2021. Only phase III randomized clinical trials with proven OS benefit relative to sunitinib were included: CheckMate 214 (nivolumab plus ipilimumab [N+I]), KEYNOTE-426 (pembrolizumab plus axitinib [P+A]), CheckMate 9ER (nivolumab plus cabozantinib [N+C]) and KEYNOTE-581 (lenvatinib plus permbrolizumab [L+P]). OS represented the primary outcome. PFS, objective response rate and AEs represented secondary outcomes. RESULTS: Overall, 3,320 patients were included. Regarding OS, N+C ranked first, followed by L+P, P+A and N+I. Regarding PFS and objective response rate, L+P ranked first, followed by N+C, P+A and N+I. Finally, N+I ranked first with respect to lowest grade 3+ AEs, followed by P+A, N+C and L+P. Differences in followup duration, risk grouping and nephrectomy rates distinguish the studies. CONCLUSIONS: N+C may provide the most favorable OS, L+P the most favorable PFS and ORRs, and N+I the lowest toxicity. Population differences may potentially undermine the generalizability and the robustness of findings of metastatic renal cell carcinoma.

BACKGROUND: Tyrosine kinase inhibitor-based adjuvant therapy showed no survival benefits for patients with high-risk nonmetastatic renal cell carcinoma (nmRCC). Five randomized immune-oncology checkpoint inhibitor trials are ongoing. We assessed the effect of stage, grade, and histologic type on cancer-specific mortality (CSM) in candidates for 1 of the 4 North American ongoing immune-oncology checkpoint inhibitor trials of high-risk nmRCC. PATIENTS AND METHODS: From the Surveillance, Epidemiology, and End Results database (2001-2015), we identified patients who had undergone surgery for nmRCC and had met the inclusion criteria for the PROSPER RCC (nivolumab in treating patients with localized kidney cancer undergoing nephrectomy), CheckMate 914 (a study comparing the combination of nivolumab and ipilimumab versus placebo in participants with localized renal cell carcinoma), KEYNOTE-564 [safety and efficacy study of pembrolizumab (MK-3475) as monotherapy in the adjuvant treatment of renal cell carcinoma post nephrectomy], or IMmotion010 [a study of atezolizumab as adjuvant therapy in participants with renal cell carcinoma (RCC) at high risk of developing metastasis following nephrectomy] trials. Kaplan-Meier and multivariable Cox regression models were used to assess the 10-year CSM rates in the overall cohort according to stage, grade, and histologic characteristics, and in 4 generated random samples according to the eligible patients for each of the 4 trials. RESULTS: Of 116,750 patients who had undergone surgery for nmRCC, 18,559 (15.9%) had fulfilled the inclusion criteria for 1 of the 4 trials. The greatest proportion of higher stage and grade combinations and sarcomatoid histologic features would have qualified for IMmotion010, followed by KEYNOTE-564, CheckMate 914, and PROSPER RCC. Multivariable Cox regression models demonstrated the most unfavorable prognosis for stage N1 grade 3/4 (hazard ratio [HR], 11.5; P < .001), stage T4N0 grade 3/4 (HR, 9.8; P < .001), and sarcomatoid histologic features (HR, 5.5; P < .001). Among the 4 random samples, the difference in the qualifying criteria resulted in the greatest versus progressively lower CSM rates in the IMmotion010, KEYNOTE-564, CheckMate 914, and PROSPER RCC trials, respectively (P < .001). CONCLUSIONS: Our findings indicate that participation in adjuvant immunotherapy trials should be predominantly encouraged for patients with high-grade stage T3, T4, and N1 and patients with any stage with sarcomatoid pathologic features.

PURPOSE: Identifying which patients are likely to benefit from cytoreductive nephrectomy (CN) for metastatic renal cell carcinoma (mRCC) is important. We tested the association between preoperative serum De Ritis ratio (DRR, Aspartate Aminotransferase/Alanine Aminotransferase) and overall survival (OS) as well as cancer-specific survival (CSS) in mRCC patients treated with CN. MATERIAL AND METHODS: mRCC patients treated with CN at different institutions were included. After assessing for the optimal pretreatment DRR cut-off value, we found 1.2 to have the maximum Youden index value. The overall population was therefore divided into 2 DRR groups using this cut-off (low, <1.2 vs. high, ≥1.2). Univariable and multivariable Cox regression analyses tested the association between DRR and OS as well as CSS. The discrimination of the model was evaluated with the Harrel's concordance index (C-index). The clinical value of the DRR was evaluated with decision curve analysis. RESULTS: Among 613 mRCC patients, 239 (39%) patients had a DRR ≥1.2. Median follow-up was 31 (IQR 16-58) months. On univariable analysis, high DRR was significantly associated with OS (hazard ratios [HR]: 1.22, 95% confidence interval [CI]: 1.01-1.46, P = 0.04) and CSS (HR: 1.23, 95% CI: 1.02-1.47, P = 0.03). On multivariable analysis, which adjusted for the effect of established clinicopathologic features, high DRR remained significantly associated with both OS (HR: 1.26, 95% CI: 1.04-1.52, P = 0.02) and CSS (HR: 1.26, 95% CI: 1.05-1.53, P = 0.01). The addition of DRR only minimally improved the discrimination of a base model that included established clinicopathologic features (C-index = 0.633 vs. C-index = 0.629). On decision curve analysis, the inclusion of DRR did not improve the net-benefit beyond that obtained by established subgroup analyses stratified by IMDC risk groups, type of systemic therapy, body mass index and sarcomatoid features, did not reveal any prognostic value to DRR. CONCLUSION: Despite the statistically significant association between DRR and OS as well as CSS in mRCC patients treated with CN, DRR does not seem to add any further prognostic value beyond that obtained by currently available features.

BACKGROUND: Tyrosine kinase inhibitor therapy (TKI) has changed the treatment paradigm of metastatic renal cell carcinoma (mRCC). The recent CARMENA and SURTIME trials challenged the role of the cytoreductive nephrectomy (CN). OBJECTIVE: To assess the impact of CN prior to TKI therapy in patients with mRCC in a real-world setting. METHODS: Overall, 262 consecutive patients with mRCC were treated with CN plus TKI or TKI only at our institution between 2000 and 2016. Patients with prior immunotherapy or metastasectomy were excluded. Multiple imputation and inverse probability of treatment weighting (IPTW) were performed to account for missing values and imbalances between the treatment groups, respectively. Unadjusted and adjusted Kaplan-Meier estimates were used to determine differences in progression-free (PFS), overall (OS), and cancer-specific survival (CSS). RESULTS: Overall, 104 (40%) patients received CN before TKI treatment. Most frequent first line therapy was Sunitinib (66%), followed by Sorafenib (20%) and Pazopanib (10%). After adjustment with IPTW, there was no difference in PFS, CSS, and OS (all P > 0.05) between the treatment groups. In subgroup analyses, CSS was improved when CN was performed in patients with sarcomatoid features and clear cell histology (P = 0.04 and P = 0.03) and PFS was improved in patients with clear cell histology when CN was performed [0.04]). CN did not improve OS in any subgroup analysis. CONCLUSION: The role of CN remains controversial. We found no difference in survival outcomes between patients treated with and without CN before TKI therapy. However, CN was associated with improved survival in specific patient subgroups. Tailored, individualized treatment is key to further improve oncological outcomes for mRCC.

ALK rearranged renal cell carcinoma (ALK-RCC) has recently been included in 2016 WHO classification as a provisional entity. In this study, we describe 12 ALK-RCCs from 8 institutions, with detailed clinical, pathological, immunohistochemical (IHC), fluorescence in situ hybridization (FISH), and next generation sequencing (NGS) analyses. Patients' age ranged from 25 to 68 years (mean, 46.3 years). Seven patients were females and five were males (M:F = 1:1.4). Tumor size ranged from 17 to 70 mm (mean 31.5, median 25 mm). The pTNM stage included: pT1a (n = 7), pT1b (n = 1), and pT3a (n = 4). Follow-up was available for 9/12 patients (range: 2 to 153 months; mean 37.6 months); 8 patients were alive without disease and one was alive with distant metastases. The tumors demonstrated heterogeneous, 'difficult to classify' morphology in 10/12 cases, typically showing diverse architectural and cellular morphologies, including papillary, tubular, tubulocystic, solid, sarcomatoid (spindle cell), rhabdoid, signet-ring cell, and intracytoplasmic vacuoles, often set in a mucinous background. Of the remaining two tumors, one showed morphology resembling mucinous tubular and spindle cell renal cell carcinoma (MTSC RCC-like) and one was indistinguishable from metanephric adenoma. One additional case also showed a focal metanephric adenoma-like area, in an otherwise heterogeneous tumor. By IHC, all tumors were diffusely positive for ALK and PAX8. In both cases with metanephric adenoma-like features, WT1 and ALK were coexpressed. ALK rearrangement was identified in 9/11 tumors by FISH. ALK fusion partners were identified by NGS in all 12 cases, including the previously reported: STRN (n = 3), TPM3 (n = 3), EML4 (n = 2), and PLEKHA7 (n = 1), and also three novel fusion partners: CLIP1 (n = 1), KIF5B (n = 1), and KIAA1217 (n = 1). ALK-RCC represents a genetically distinct entity showing a heterogeneous histomorphology, expanded herein to include unreported metanephric adenoma-like and MTSC RCC-like variants. We advocate a routine ALK IHC screening for "unclassifiable RCCs" with heterogeneous features.
