Abstract
Purpose Vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) are being used for the first-line treatment of metastatic clear cell renal cell carcinoma (mccRCC). Here, we set out to explore associations between genomic statuses, gene expression clusters and clinical outcomes of mccRCCs upon the application of VEGFR-TKIs. Methods A retrospective study of 56 patients with mccRCC who received first-line VEGFR-TKIs and who underwent genomic profiling and whole transcriptome sequencing was conducted. Survival analysis was carried out using log-rank tests and Cox regression analyses, and Kaplan–Meier curves were plotted. Clustering was performed using the K-means method. Results Among the 56 patients tested, 17 harbored DNA Damage and Repair (DDR) pathway alterations and 35 VHL mutations. The median progression-free survival (PFS) rates for the DDR and VHL alteration groups were 18 and 18 months, respectively, compared with 14 and 10 months for the nonmutant groups. DDR mutations, VHL mutations and co-mutations were identified as prognostic biomarkers of a longer PFS (p = 0.017, 0.04, 0.014). K-means clustering of expressed transcripts revealed three clusters of 40 patients: C_1, C_2 and C_3. The C_1 cluster exhibited the best PFS and objective response rate (ORR) to TKI therapy, with the highest proportion of DDR and VHL mutations. Further analysis of the tumor immune environment revealed that the C_1 cluster was enriched in activated CD8 T cells and effector CD4 T cells, whereas the C_2 cluster was enriched in eosinophils, mast cells and DC cells and, thus, in immunosuppressive cells. Conclusions We found that patients with mccRCC harboring DDR and VHL alterations were more likely to benefit from first-line VEGF-TKI systemic therapy than patients with wild-type disease. In addition, we found that a three-cluster prognostic model based on gene expression can predict PFS and ORR, which was well-matched with activated TIL infiltration.

Abstract
Background People living with HIV (PLWH) have a higher risk for cancer compared to the general population. The prevalence of renal cell carcinoma (RCC) in PLWH has gradually increased in recent years, but relevant data on outcomes after surgery are scarce. We thus evaluated long-term outcomes after surgery in RCC patients with and without HIV. Methods This retrospective study included 67 patients with RCC, both HIV positive or negative, who underwent surgical treatment in our hospital between January 2012 and January 2021. Demographic details, clinical data, and cancer status were collected. We set the day of surgery as the baseline. The co-primary end points in this time-to-event analysis were overall survival and progression-free survival. We used a multivariate Cox model to compare the prognosis of PLWH and HIV-negative patients and present Kaplan–Meier curves for the co-primary end points. Results Of 261 consecutive patients, 18 patients who forwent treatment before surgery, 133 cases with incomplete data, 16 patients classified as clinical stage IV, 11 PLWH patients did not received antiretroviral therapy and 16 patients with metastasis were excluded from the main analysis. Of the remaining 67 patients, 33 individuals had HIV and the other 34 did not. The median overall survival was 74.9 months (95% confidence interval [CI] = 64.6 to 85.2) in PLWH and 96.4 months (95% CI = 90.0 to 102.9) in the HIV-negative group. Progression-free survival was 66.4 months (95% CI = 53.5 to 79.3) and 90.6 months (95% CI = 81.1 to 100.1), respectively. RCC patients with HIV who underwent surgery had a shorter survival time (hazard ratio [HR] = 2.8, 95% CI = 1.1 to 7.0, p = 0.016) and an increased incidence of tumor progression (HR = 2.7, 95% CI = 1.1 to 6.8, p = 0.028). Univariate and multivariate Cox regression analyses showed that a lower ratio of CD4+ T cells to CD8+ T cells (adjusted odds ratio = 0.092, 95% CI = 0.01 to 0.70, p = 0.022) was associated with worse survival among PLWH. Conclusion In this retrospective analysis of RCC patients who underwent surgery, PLWH had worse overall survival and shorter progression-free survival compared to HIV-negative cases.

Abstract
Over the last decade, there have been substantial progress in the field of systemic therapy for advanced renal cell carcinoma. Through the transition from treatment with cytokines to molecular-targeted agents, and currently to immuno-oncology drugs, the prognostic outcomes of patients with advanced renal cell carcinoma have been markedly improved. In particular, based on the promising outcomes of recently conducted pivotal randomized clinical trials, immuno-oncology drug-based combination therapy by either dual immune checkpoint inhibition or combined inhibition of an immune checkpoint and tyrosine kinase, is currently regarded as a standard of care for treatment-naïve advanced renal cell carcinoma patients. However, insufficient data are available with respect to the selection of optimal systemic therapies for advanced renal cell carcinoma in the first-line setting due to the lack of a head-to-head comparison between approved immuno-oncology drug-based combination therapies. In this review, therefore, we summarize interesting findings associated with first-line combination therapies for advanced renal cell carcinoma obtained from both randomized clinical trials and real-world clinical practices, in order to present useful guidance to help make treatment decisions for patients with treatment-naïve advanced renal cell carcinoma.

Abstract
Abstract
Background
The objective of the present study was to evaluate the prognostic impact of the upper urinary tract cancer status on recurrence-free survival and progression-free survival, and to develop risk stratification systems that include the upper urinary tract cancer status for patients with non-muscle invasive bladder cancer.
Patients and Methods
The present study included 40 (upper urinary tract cancer-non-muscle invasive bladder cancer group) and 285 (non-muscle invasive bladder cancer alone group) patients with and without a history of prior or concomitant upper urinary tract cancer, respectively. Nine clinicopathological findings between the two groups were compared, and risk stratification systems for the recurrence and progression of non-muscle invasive bladder cancer were developed.
Results
Recurrence-free survival and progression-free survival in the upper urinary tract cancer-non-muscle invasive bladder cancer group were significantly inferior to those in the NMIBC alone group (P < 0.001 and P = 0.006, respectively). Multivariate analyses identified the following independent prognosticators: multiplicity and upper urinary tract cancer status for recurrence-free survival, and pT category and upper urinary tract cancer status for progression-free survival. Significant differences were noted by the risk stratification systems based on the positive number of independent predictors of recurrence-free survival and progression-free survival (P < 0.001 and P = 0.007, respectively). The concordance indices of recurrence-free survival were 0.627, 0.588 and 0.499 in this study stratification, EORTC risk table and CUETO model, respectively. Those of progression-free survival were 0.752, 0.740 and 0.714, respectively.
Conclusion
The present results suggest the significant impact of a history of prior or concomitant UUTC on recurrence-free survival and progression-free survival in non-muscle invasive bladder cancer patients, and risk stratification systems that include the upper urinary tract cancer status for the recurrence and progression of non-muscle invasive bladder cancer are promising tools for predicting the outcomes of these patients.

Combination of C-Reactive Protein and Neutrophil-to-Lymphocyte Ratio as a Novel Prognostic Index in Patients With Bladder Cancer After Radical Cystectomy. Front Oncol 2021; 11:762470. [PMID: 34926263 PMCID: PMC8674495 DOI: 10.3389/fonc.2021.762470] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Accepted: 11/11/2021] [Indexed: 11/13/2022] Open
Abstract
Background Inflammation is widely considered an important hallmark of cancer and associated with poor postoperative survival. The objective of this study is to assess the significance of preoperative C-NLR, a new inflammation-based index that includes preoperative C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR), on therapeutic outcomes for bladder cancer (BC) patients after radical cystectomy (RC). Materials and Methods BC patients who underwent RC between 2010 and 2019 were retrospectively analyzed from our medical center. The predictive effect of CRP, NLR, and C-NLR on the survival of BC patients were analyzed by the receiver operating characteristic (ROC) curves. The relationship between C-NLR and postoperative survival was investigated by Cox regression. The corresponding nomograms were built based on the Cox regression results of overall survival (OS) and disease-free survival (DFS), which were further validated by ROC curves, decision curve analysis (DCA) curves, and calibration curves. Results Of the 199 eligible patients, 83 (41.70%) were classified as high C-NLR group and the remaining 116 (58.30%) were classified as low C-NLR group. ROC analysis showed that C-NLR had the largest area under curve (AUC) compared to CRP and NLR. Multivariate analysis revealed that T-stage and C-NLR [high C-NLR vs. low C-NLR, hazard ratio (HR) = 2.478, 95% confidence interval (CI), 1.538–3.993, p < 0.001] were independent predictors of OS, whereas T-stage, M-stage, and C-NLR (high C-NLR vs. low C-NLR, HR = 2.817, 95% CI, 1.667–4.762, p < 0.001) were independent predictors of DFS. ROC and DCA analysis demonstrated better accuracy and discrimination of 3- and 5-year OS and DFS with C-NLR-based nomogram compared to TNM stage. The calibration curve reconfirmed the accurate predicting performance of nomograms. Conclusion C-NLR is a reliable predictor of long-term prognosis of BC patients after RC and will contribute to the optimization of individual therapy for BC patients.

Combination of Albumin-Globulin Score and Sarcopenia to Predict Prognosis in Patients With Renal Cell Carcinoma Undergoing Laparoscopic Nephrectomy. Front Nutr 2021; 8:731466. [PMID: 34631767 PMCID: PMC8495413 DOI: 10.3389/fnut.2021.731466] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Accepted: 08/27/2021] [Indexed: 11/13/2022] Open
Abstract
We conducted a multicenter clinical study to construct a novel index based on a combination of albumin-globulin score and sarcopenia (CAS) that can comprehensively reflect patients' nutritional and inflammatory status and assess the prognostic value of CAS in renal cell carcinoma (RCC) patients. Between 2014 and 2019, 443 patients from 3 centers who underwent nephrectomy were collected (343 in the training set and 100 in the test set). Kaplan-Meier curves were employed to analyze the impact of albumin-globulin ratio (AGR), albumin-globulin score (AGS), sarcopenia, and CAS on overall survival (OS) and cancer-specific survival (CSS) in RCC patients. Receiver operating characteristic (ROC) curves were used to assess the predictive ability of AGR, AGS, sarcopenia, and CAS on prognosis. High AGR, low AGS, and nonsarcopenia were associated with higher OS and CSS. According to CAS, the training set included 60 (17.5%) patients in grade 1, 176 (51.3%) patients in grade 2, and 107 (31.2%) patients in grade 3. Lower CAS was linked to longer OS and CSS. Multivariate Cox regression analysis revealed that CAS was an independent risk factor for OS (grade 1 vs. grade 3: aHR = 0.08; 95% CI: 0.01-0.58, p = 0.012; grade 2 vs. grade 3: aHR = 0.47; 95% CI: 0.25-0.88, p = 0.018) and CSS (grade 1 vs. grade 3: aHR = 0.12; 95% CI: 0.02-0.94, p = 0.043; grade 2 vs. grade 3: aHR = 0.31; 95% CI: 0.13-0.71, p = 0.006) in RCC patients undergoing nephrectomy. Additionally, CAS had higher accuracy in predicting OS (AUC = 0.687) and CSS (AUC = 0.710) than AGR, AGS, and sarcopenia. In addition, similar results were obtained in the test set. The novel index CAS developed in this study, which reflects patients' nutritional and inflammatory status, can better predict the prognosis of RCC patients.

Abstract
C-Reactive Protein (CRP) is associated with diverse outcomes in patients with, or suspected to have, genitourinary malignancies. CRP levels have been shown to be associated with the probability of a prostate cancer diagnosis in patients with elevated PSA, the probability of biochemical recurrence following definitive treatment for localized prostate cancer, and decreased overall survival for patients with advanced disease. In patients with bladder and kidney cancers, CRP levels have been associated with disease progression, stage, and cancer-specific survival. Despite the abundance of correlative studies, the relationship between CRP levels and genitourinary cancer pathogenesis is not clearly understood. Here, we review the evidence for CRP as a biomarker in genitourinary (GU) cancers, with specific focus on potential clinical applications.
