AbstractThis retrospective, five-multicenter study was aimed to evaluate the prognostic impact of pathologic nodal positivity on recurrence-free (RFS), metastasis-free (MFS), overall (OS), and cancer-specific (CSS) survivals in patients with non-metastatic renal cell carcinoma (nmRCC) who underwent either radical or partial nephrectomy with/without LN dissection. A total of 4236 nmRCC patients was enrolled between 2000 and 2012, and followed up through the end of 2017. Survival measures were compared between 52 (1.2%) stage pT1-4N1 (LN+) patients and 4184 (98.8%) stage pT1-4N0 (LN−) patients using Kaplan–Meier analysis with the log-rank test and Cox regression analysis to determine the prognostic risk factors for each survival measure. During the median 43.8-month follow-up, 410 (9.7%) recurrences, 141 (3.3%) metastases, and 351 (8.3%) deaths, including 212 (5.0%) cancer-specific deaths, were reported. The risk factor analyses showed that predictive factors for RFS, CSS, and OS were similar, whereas those of MFS were not. After adjusting for significant clinical factors affecting survival outcomes considering the hazard ratios (HR) of each group, the LN+ group, even those with low pT stage, had similar to or worse survival outcomes than the pT3N0 (LN−) group in multivariable analysis and had significantly more relationship with RFS than MFS. All survival measures were significantly worse in pT1-2N1 patients (MFS/RFS/OS/CSS; HR 4.12/HR 3.19/HR 4.41/HR 7.22) than in pT3-4N0 patients (HR 3.08/HR 2.92/HR 2.09/HR 3.73). Therefore, LN+ had an impact on survival outcomes worse than pT3-4N0 and significantly affected local recurrence rather than distant metastasis compared to LN− in nmRCC after radical or partial nephrectomy.

Purpose Renal cell carcinoma (RCC) is considered a cytokine-responsive tumor. The clinical course of a patient may thus be influenced by the patient's capacity to produce distinct cytokines. Therefore, cytokine gene polymorphisms in RCC patients were analyzed to determine haplotype combinations with prognostic significance. Patients and Methods A selection of 21 single nucleotide polymorphisms within the promoter regions of 13 cytokine genes were analyzed in a cross-sectional single-center study of 80 metastatic RCC patients. Univariate and multivariate analyses and the Cox forward-stepwise regression model were chosen to assess genetic risk factors. Results Multivariate Cox regression analysis confirmed by a bootstrap technique identified the heterozygous IL4 genotype −589T−33T/−589C−33C as an independent prognostic risk factor (risk ratio, 3.1; P < .01; 95% CI, 1.4 to 6.9; adjusted for age, sex, and nuclear grading) in metastatic RCC patients. IL4 haplotype −589T−33T and −589C−33C were found with a frequency of 0.069 and 0.925, respectively, which represents a two-fold decrease of IL4 haplotype −589T−33T (P < .01) and an increase of IL4 haplotype −589C−33C frequency (P < .05) in metastatic RCC compared with other white reference study populations. The median overall survival was decreased 3.5-fold (P < .05) in heterozygote patients carrying IL4 haplotype −589T−33T and −589C−33C (3.78 months) compared with patients homozygote for IL4 haplotype −589C−33C (13.44 months). In addition, a linkage disequilibrium between the IL4 gene and the KIF3A gene was detected. Conclusion Our findings indicate that IL4 promoter variants influence prognosis in patients with metastatic RCC and suggest that genetically determined interleukin-4 (IL-4) production affects the clinical course of the disease possibly through regulation of immune surveillance.

Perirenal Fat

416 Background: The renal cell carcinoma (RCC) TNM system merges perirenal fat invasion (PFI) and renal vein invasion (RVI) as stage pT3a despite limited evidence concerning their prognostic equivalence. Additionally, the prognostic value of PFI compared to pT1-pT2 tumors remains controversial. Methods: Data of 7,595 pT1a-pT3a RCC patients undergoing radical nephrectomy or nephron-sparin surgery were pooled from 12 European and U.S. centers (1999-2010). Patients were grouped according to stages and presence of PFI/RVI, i.e., pT1-2N0M0 (n=6,137; 80.8%), pT3aN0M0+PFI (n=1,036; 13.6%), and pT3aN0M0 (RVI±PFI; n=422; 5.6%). Cancer-specific survival (CSS) was estimated by Kaplan-Meier method. Univariate and multivariable Cox proportional-hazards regression models, sensitivity and discrimination analyses were conducted to evaluate the impact of clinico-pathological parameters on cancer-specific mortality (CSM). Results: Compared to stage pT1-2, patients staged pT3a were significantly more frequently male (58.9 vs. 53.1%), older (65 vs. 62.1 yrs), more often had clear cell RCC (86.1 vs. 77.7%), Fuhrman grade 3-4 (30.5 vs. 13.4%), tumor size >7 cm (39.6% vs. 13%), and less often underwent NSS (7.1 vs. 36.6%; each p<0.001). On multivariable analysis, CSM of both patients with PFI and RVI±PFI was significantly enhanced compared to pT1-2 patients (HR 1.96 and 2.14, resp.; p<0.001), whereas patients featuring PFI only and RVI±PFI did not differ (HR 0.92; p=0.48). Tumor size instead significantly influenced CSM in stage pT3a (HR 1.07; p<0.001) with a 7 cm cut-off yielding the highest c-index. Conclusions: Since the prognostic impact of PFI and RVI on CSM seems to be comparable, merging both as stage pT3a might be justified. Enhanced prognostic discrimination of stage pT3a RCC patients appears to be possible by employing a 7 cm tumor size cut-off within an alternative staging system.

Cd73 Expression

BackgroundCD73–adenosine signaling in the tumor microenvironment is immunosuppressive and may be associated with aggressive renal cell carcinoma (RCC). We investigated the prognostic significance of CD73 protein expression in RCC leveraging nephrectomy samples. We also performed a complementary analysis using The Cancer Genome Atlas (TCGA) dataset to evaluate the correlation of CD73 (ecto-5′-nucleotidase (NT5E), CD39 (ectonucleoside triphosphate diphosphohydrolase 1 (ENTPD1)) and A2 adenosine receptor (A2AR; ADORA2A) transcript levels with markers of angiogenesis and antitumor immune response.MethodsPatients with RCC with available archived nephrectomy samples were eligible for inclusion. Tumor CD73 protein expression was assessed by immunohistochemistry and quantified using a combined score (CS: % positive cells×intensity). Samples were categorized as CD73negative (CS=0), CD73low or CD73high (< and ≥median CS, respectively). Multivariable Cox regression analysis compared disease-free survival (DFS) and overall survival (OS) between CD73 expression groups. In the TCGA dataset, samples were categorized as low, intermediate and high NT5E, ENTPD1 and ADORA2A gene expression groups. Gene expression signatures for infiltrating immune cells, angiogenesis, myeloid inflammation, and effector T-cell response were compared between NT5E, ENTPD1 and ADORA2A expression groups.ResultsAmong the 138 patients eligible for inclusion, ‘any’ CD73 expression was observed in 30% of primary tumor samples. High CD73 expression was more frequent in patients with M1 RCC (29% vs 12% M0), grade 4 tumors (27% vs 13% grade 3 vs 15% grades 1 and 2), advanced T-stage (≥T3: 22% vs T2: 19% vs T1: 12%) and tumors with sarcomatoid histology (50% vs 12%). In the M0 cohort (n=107), patients with CD73high tumor expression had significantly worse 5-year DFS (42%) and 10-year OS (22%) compared with those in the CD73negative group (DFS: 75%, adjusted HR: 2.7, 95% CI 1.3 to 5.9, p=0.01; OS: 64%, adjusted HR: 2.6, 95% CI 1.2 to 5.8, p=0.02) independent of tumor stage and grade. In the TCGA analysis, high NT5E expression was associated with significantly worse 5-year OS (p=0.008). NT5E and ENTPD1 expression correlated with higher regulatory T cell (Treg) signature, while ADORA2A expression was associated with increased Treg and angiogenesis signatures.ConclusionsHigh CD73 expression portends significantly worse survival outcomes independent of stage and grade. Our findings provide compelling support for targeting the immunosuppressive and proangiogenic CD73–adenosine pathway in RCC.

Effect Of Age

Objective: Based on combined data for 4880 patients, 2 previous studies reported that advanced age is a predictor of increased renal cell carcinoma–specific mortality (RCC-SM). We explored the effect of age in cubic spline analyses to identify the age groups with the most elevated risk for renal cell carcinoma (RCC).Methods: Our study included 3595 patients from 14 European centres who had partial or radical nephrectomies. We used the Kaplan–Meier method to compile life tables, and we performed Cox regression analyses to assess RCC-SM. Covariates included age at diagnosis, sex, TNM (tumour, node, metastasis) stage, tumour size, Fuhrman grade, symptom classification and histological subtype.Results: Age ranged from 10 to 89 (mean 63, median 67) years. The median duration of follow-up was 2.9 years. The median survival for the cohort was 13.4 years. Stage distribution was as follows: 1915 patients (53.3%) had stage I disease, 388 (10.8%) had stage II, 895 (24.9%) had stage III and 397 (11.0%) had stage IV disease. In multivariate analyses, we coded age at diagnosis as a cubic spline, and it achieved independent predictor status (p < 0.001). The risk of RCC-SM was lowest among patients younger than 50 years. We observed an increase in RCC-SM until the age of 50, at which point the level of risk reached a plateau. We observed a second increase among patients aged 75–89 years. We found similar patterns when we stratified patients according to the 2002 American Joint Committee on Cancer (AJCC) stages.Conclusion: The effect of age shows prognostic significance and indicates that follow-up and possibly secondary treatments might need to be adjusted according to the age of the patient.

684 Background: Immuno-Oncology (IO) combinations are standard of care first-line treatment for metastatic renal cell carcinoma (mRCC). Data on therapy with vascular endothelial growth factor (VEGF) tyrosine kinase inhibitors (TKI) post-progression on IO-combination therapy are limited. Methods: Using the IMDC, a retrospective analysis was done on mRCC patients treated with second-line VEGF TKIs after receiving IO combination therapy. Patients received first-line ipilimumab+nivolumab (IOIO) or anti-PD(L)1+anti-VEGF (IOVE). Baseline variables and second-line IMDC risk factors were collected. Overall response rates (ORR), time to treatment failure (TTF) and overall survival (OS) were determined. Multivariable Cox regression analysis was performed. Results: 142 patients were included. 75 patients received IOIO and 67 received IOVE pretreatment. The ORR of 2nd line therapy was 17/46 (37%) and 7/57 (12%) in the IOIO and IOVE pretreated groups, respectively (p<0.01). 2nd-line TTF was 5.4 months (95% CI 4.1-8.3) for the IOIO- and 4.6 months (95% CI 3.7-5.8) for the IOVE-pretreated group (p=0.37). 2nd-line median OS was 17.2 months (95% CI 10.8-35.1) and 11.8 months (95% CI 9.9-21.3) for the prior IOIO and IOVE groups, respectively (p=0.13). The hazard ratio adjusted by IMDC for IOVE vs IOIO pretreatment was 1.22 (95% CI 0.73-2.07, p=0.45) for 2nd line TTF and 1.43 (95% CI 0.74-2.8, p=0.29) for 2nd line OS. Conclusions: VEGF TKIs show activity after combination IO therapy. Response rates are higher in patients treated with VEGF TKIs after first-line IOIO compared to after IOVE. In patients with VEGF TKI after IOIO or IOVE, no difference in OS and TTF was observed.[Table: see text]

655 Background: The presence of brain metastases and bone metastases are generally understood to herald worsened prognosis following nephrectomy in patients with renal cell carcinoma (RCC). However, we sought to determine the effect of bone metastases on outcomes when already present at the time of cytoreductive radical nephrectomy (RN). Methods: Multicenter retrospective analysis of mRCC patients from the REgistry of MetAstatic RCC) REMARCC. Demographics, clinical variables, and outcomes were collected. Patients were stratified into low, medium, and high-risk groups based on Motzer Criteria, and analysis of impact of bone metastases was conducted within each group utilizing Kaplan-Meier analysis (KMA). Multivariable analysis (MVA) was utilized to identify predictors for outcomes. Primary outcome was progression-free survival (PFS) and secondary outcome was overall survival (OS). Results: A total of 447 patients (low- n=30, intermediate- n=208, and high-risk mRCC n=123, median follow-up 14.3 months) were included in the analysis. 124 patients had bone metastases and 323 had mRCC but no bone metastases. No significant demographic differences were noted between groups. KMA (Figure) showed no difference in median PFS for bone metastases vs. non bone metastases groups (6.1 vs. 6.4 months, p=0.973). KMA showed no difference in median OS (25.5 vs. 26.5 months, p=0.958). Similarly, stratification of patients into different Motzer risk categories did not demonstrate difference between bone vs. none bone mRCC for PFS and OS. MVA for PFS demonstrated increasing Motzer risk category (low risk referent vs. intermediate OR 1.89, p=0.006, high risk OR 3.24, p<0.001) as independent predictors. MVA for OS revealed increasing Motzer risk category (low ref, vs. intermediate OR 1.88, p=0.033, high risk 5.17, p<0.001) as being predictive. In neither analysis was presence of bone metastases significant (PFS p=0.690, OS p=0.268). Conclusions: Presence of bone metastases does not independently predict survival or oncologic outcomes in mRCC. While further validation is needed, the prognostic significance of bone metastases may be less than previously thought.

Today, the long non-coding RNA MALAT1 is considered to be one of the major RNAs involved in the emergence and metastasizing of various malignant tumours. Recent experiments have shown that MALAT1 plays an important role in the onset and progression of kidney cancer as well. It was found that cancer patient survival depends on the level of MALAT1 gene expression. The aim of the study was to investigate the possible association between rs3200401 MALAT1 gene polymorphism and age of kidney cancer onset among Ukrainian patients. Materials and methods. The venous blood of 101 patients with clear cell renal cell carcinoma (42 women and 59 men) was used for study. Determination of MALAT1 gene rs320040 polymorphism was performed by the Real-Time polymerase chain reaction method using TaqManSNP Assay C_3246069_10 components. Statistical analysis of the data obtained was performed using SPSS (version 17.0). To test the possible association between rs3200401 genotypes and the age of kidney cancer onset Kaplan-Meier and Cox regression techniques were used. P value < 0.05 was considered as statistically significant. Results. The obtained results of MALAT1 gene rs3200401 polymorphic site genotyping revealed that 71 (70.3%) patients with renal cell carcinoma had CC genotype, 29 (28.7%) – CT, 1 (1%) – TT genotype. Survival analysis by Kaplan-Meier method showed that life expectancy until the tumour occurrence was not related to rs3200401 locus (log rank P = 0.449 – for codominant model; log rank P = 0.847 – for dominant model). The results of Cox regression analysis also showed no link between MALAT gene rs3200401-site and risk of renal cell carcinoma development (P > 0.05). No statistically significant results were found after adjustment for sex, body mass index, metastasis, smoking and drinking habits (P > 0.05). Conclusions. The rs3200401 gene polymorphism of long non-coding RNA MALAT1 is not associated with the age of kidney cancer onset in Ukrainian population.
