RESUMO
BACKGROUND: Kidney transplantation (KT) leads to body composition change, particularly increasing the fat mass. However, limited researches have focused on the long-term follow-up of these changes and factors influencing body composition after KT. METHODS: This study evaluated body composition in 31 adult KT recipients, measuring body mass index (BMI), the psoas muscle mass index (PMI) representing muscle mass, visceral and subcutaneous adipose tissue (VAT and SAT) representing fat mass, and skeletal muscle radiodensity (SMR) representing muscle quality before KT and at 2, 4, and 6 years posttransplantation using computed tomography. Linear mixed models (LMM) analyzed temporal changes and contributing factors, while growth curve models assessed influence of these factors on body composition changes posttransplantation. RESULTS: Following KT, BMI, and PMI remained stable, while SAT increased significantly, revealing a 1.30-fold increase from baseline 2 years after transplantation. Similarly, a substantial increase in VAT was observed, with a 1.47-fold increase from baseline 2 years after transplantation with a further 1.75-fold increase 6 years after transplantation. In contrast, SMR decreased with a 0.86-fold decrease from baseline after 2 years. VAT increase was significantly influenced by the interaction between posttransplantation and dialysis duration. Growth curve models confirmed this interaction effect persistently influenced VAT increase posttransplantation. CONCLUSIONS: The study revealed that KT promoted significant alterations in body composition characterized by increase in the VAT and SAT and a decline in SMR. Notably, dialysis duration and its interaction with posttransplantation duration emerged as significant factors influencing VAT increase.
RESUMO
BACKGROUND: Nivolumab plus ipilimumab (NIVO + IPI) is the first-line treatment for patients with metastatic renal cell carcinoma (mRCC). While approximately 40% of patients treated with NIVO + IPI achieve a durable response, 20% develop primary resistance with severe consequences. Therefore, there is a clinical need for criteria to select patients suitable for NIVO + IPI therapy to optimize its therapeutic efficacy. Accordingly, our aim was to evaluate the association between candidate biomarkers measured before treatment initiation and survival. METHODS: This was a multi-institutional, retrospective, cohort study of 183 patients with mRCC treated with systematic therapies between August 2015 and July 2023. Of these, 112 received NIVO + IPI as first-line therapy: mean age, 68 years; men, 83.0% (n = 93), and clear cell histology, 80.4% (n = 90). Univariable and multivariable analyses were used to evaluate associations between biomarkers and survival. RESULTS: On univariate analysis, high C-reactive protein and systemic index, a high neutrophil-to-lymphocyte and platelet-to-lymphocyte ratio, and a low lymphocyte-to-monocyte ratio (LMR) were associated with shorter overall survival (OS). On multivariable analysis, a LMR ≤ 3 was retained as an independent factor associated to shorter OS with the highest accuracy (C-index, 0.656; hazard ratio, 7.042; 95% confidence interval, 2.0-25.0; p = 0.002). CONCLUSION: A low LMR may identify patients who would be candidate for NIVO + IPI therapy for mRCC.

OBJECTIVES: Immune checkpoint inhibitors and enfortumab vedotin have opened new avenues for sequential treatment strategies for locally advanced/metastatic urothelial carcinoma (la/mUC). In the pre-enfortumab vedotin era, many patients could not receive third-line treatment owing to rapid disease progression and poor general status. This study aimed to analyze real-world sequential treatment practices for la/mUC in Japan, with a focus on patients who do not receive third-line treatment. METHODS: We analyzed data for 1023 la/mUC patients diagnosed between January 2020 and December 2021 at 54 institutions from a Japanese nationwide cohort. RESULTS: At the median follow-up of 28.5 months, the median overall survival from first-line initiation for 905 patients who received systemic anticancer treatment was 19.1 months. Among them, 81% and 32% received second- and third-line treatment. Notably, 52% had their treatment terminated before the opportunity for third-line treatment. Multivariate logistic regression analysis revealed that low performance status (≥1), elevated neutrophil-to-lymphocyte ratio (≥3), and low body mass index (<21 kg/m2) at the start of first-line treatment were independent risk factors for not proceeding to third-line treatment (p = 0.0024, 0.0069, and 0.0058, respectively). In this cohort, 33% had one of these factors, 36% had two, and 15% had all three. CONCLUSIONS: This study highlights the high frequency of factors associated with poor tolerance to anticancer treatment in la/mUC patients. The findings suggest the need to establish optimal sequential treatment strategies, maximizing efficacy within time and tolerance constraints, while concurrently providing strong supportive care, considering immunological and nutritional aspects.

BACKGROUND: Several clear cell renal cell carcinoma (ccRCC) cases harbour fibroblast growth factor receptor 4 (FGFR4) gene copy number (CN) gains. In this study, we investigated the functional contribution of FGFR4 CN amplification in ccRCC. METHODS: The correlation between FGFR4 CN determined via real-time PCR and protein expression evaluated using western blotting and immunohistochemistry was assessed in ccRCC cell lines (A498, A704, and 769-P), a papillary RCC cell line (ACHN), and clinical ccRCC specimens. The effect of FGFR4 inhibition on ccRCC cell proliferation and survival was assessed via either RNA interference or using the selective FGFR4 inhibitor BLU9931, followed by MTS assays, western blotting, and flow cytometry. To investigate whether FGFR4 is a potential therapeutic target, a xenograft mouse model was administered BLU9931. RESULTS: 60% of ccRCC surgical specimens harboured an FGFR4 CN amplification. FGFR4 CN was positively correlated with its protein expression. All ccRCC cell lines harboured FGFR4 CN amplifications, whereas ACHN did not. FGFR4 silencing or inhibition attenuated intracellular signal transduction pathways, resulting in apoptosis and suppressed proliferation in ccRCC cell lines. BLU9931 suppressed tumours at a tolerable dose in the mouse model. CONCLUSION: FGFR4 contributes to ccRCC cell proliferation and survival following FGFR4 amplification, making it a potential therapeutic target for ccRCC.

INTRODUCTION: In this study, we evaluated whether SARS-CoV-2 mRNA vaccines induce anti-human leukocyte antigen (HLA) antibodies and anti- ABO blood type antibodies (ABOAb) in kidney transplant recipients (KTRs). METHODS: Sixty-three adult KTRs with functioning grafts who received two doses of the SARS-CoV-2 mRNA vaccine were enrolled in this cohort. Changes in anti-ABO blood type immunoglobulin IgM and IgG antibody titers, flow panel reactive antibody (PRA), de novo donor-specific anti-human leukocyte antigen antibodies (DSA), and kidney allograft function before and after vaccination were evaluated. RESULTS: Only one patient experienced conversion from negative to positive flow PRA after vaccination. However, there was no DSA in single antigen flow-bead assays. The mean fluorescence intensity (MFI) in the eight DSA-positive recipients did not significantly change before and after vaccination (p = .383), and no additional DSA was produced after vaccination in those patients. No significant elevation of ABOAb titer was observed for either IgM (p = .438) or IgG (p = .526) after vaccination. There was no significant deterioration in estimated glomerular filtration rate (eGFR) after vaccination (p = .877) or elevation of the urine protein-to-creatinine ratio (p = .209) after vaccination. One episode of AMR was observed in addition to a preexisting acute cellular rejection. CONCLUSIONS: The SARS-CoV-2 mRNA vaccine did not induce anti-HLA antibody or ABOAb production in KTRs.

BACKGROUND: The Modified International Metastatic Renal Cell Carcinoma Dataset Consortium model (mIMDC) is a preoperative prognostic model for pT3cN0M0 renal cell carcinoma (RCC). This study aimed to validate the mIMDC and to construct a new model in a localized and locally advanced RCC (LLRCC). METHODS: A database was established (the Michinoku Japan Urological Cancer Study Group database) consisting of 79 patients who were clinically diagnosed with LLRCC (cT3b/c/4NanyM0) and underwent radical nephrectomy from December 2007 to May 2018. Using univariable and multivariable analyses, we retrospectively analyzed disease-free survival (DFS) and overall survival (OS) in this database, constructed a new prognostic model according to these results, and estimated the model fit using c-index on the new and mIMDC models. RESULTS: Independent poorer prognostic factors for both DFS and OS include the following: ≥ 1 Eastern Cooperative Oncology Group performance status, 2.0 mg/dL C-reactive protein, and > upper normal limit of white blood cell count. The median DFS in the favorable (no factor), intermediate (one factor), and poor-risk group (two or three factors) was 76.1, 14.3, and 4.0 months, respectively (P < 0.001). The 3-year OS in the favorable, intermediate, and poor-risk group were 92%, 44%, and 0%, respectively (P < 0.001). The c-indices of the new and mIMDC models were 0.67 and 0.60 for DFS (P = 0.060) and 0.74 and 0.63 for OS (P = 0.012), respectively. CONCLUSION: The new preoperative prognostic model in LLRCC can be used in patient care and clinical trials.

Human leukocyte antigen class I (HLA-I) genotypes are suggested to influence the cancer response to checkpoint blockade immunotherapy. This study assessed the impact of germline HLA genotypes on clinical outcomes in patients with chemoresistant advanced urothelial cancer (UC) treated with pembrolizumab. Zygosity, supertypes, evolutionary divergency, and specific alleles of germline HLA-I and -II were evaluated using the Luminex technique in 108 patients with chemoresistant metastatic or locally advanced UC treated with pembrolizumab. Among the 108 patients, 69 died and 83 showed radiographic progression during follow-up. Homozygous for at least one HLA-I locus, absence of the HLA-A03 supertype, and high HLA-I evolutionary divergence were associated with a radiographic response, but were not associated with survival outcomes. Patients with the HLA-DQB1*03:01 allele had significantly lower disease control rates than patients without the allele (17.4% vs. 53.8%, p = 0.002); its presence was also an independent risk factor for progressive disease (hazard ratio 4.35, 95% confidence interval 1.03-18.46). Furthermore, patients with the HLA-DQB1*03:01 allele had significantly worse progression-free survival than patients without the allele (median progression-free survival 3.1 vs. 4.8 months, p = 0.035). There was no significant relationship between any HLA status and the incidence of severe adverse events. Several germline HLA genotypes, especially HLA-DQB1*03:01, may be associated with radiographic progression. However, their impact on treatment response is limited, and germline HLA genotypes was not independently associated with survival outcomes. Further prospective studies are needed to confirm the relationship between germline HLA genotypes and clinical outcomes in patients with chemoresistant advanced UC treated with pembrolizumab.

OBJECTIVES: To assess the impact of histological variants on survival and response to treatment with pembrolizumab in patients with chemo-resistant urothelial carcinoma (UC). PATIENTS AND METHODS: The medical records of 755 patients with advanced UC who received pembrolizumab were reviewed retrospectively. Patients were classified into pure UC (PUC) and each variant. Best overall response (BOR) and overall survival (OS) were compared between the groups using a propensity score matching (PSM). RESULTS: Overall, 147 (19.5%) patients harboured any histological variant UC (VUC). After PSM, there were no significant differences in the objective response rate (ORR, 24.5% vs 17.3%, P = 0.098) or disease control rate (DCR, 36.7% vs 30.2%, P = 0.195) when comparing patients with any VUC and PUC. Furthermore, any VUC, as compared with PUC, was associated with a similar risk of death (hazard ratio [HR] 0.90, 95% confidence interval [CI] 0.68-1.20; P = 0.482). Squamous VUC, which was the most frequent variant in the cohort, had a comparable ORR, DCR and OS as compared with PUC or non-squamous VUC. The patients with sarcomatoid VUC (n = 19) had significantly better ORR (36.8%, P = 0.031), DCR (52.6%, P = 0.032), and OS (HR 0.37, 95% CI 0.15-0.90; P = 0.023) compared to patients with PUC. CONCLUSIONS: The presence of variant histology did not seem to affect BOR or OS after pembrolizumab administration in patients with chemo-resistant UC. The patients with sarcomatoid VUC achieved favourable responses and survival rates compared to PUC.

BACKGROUND: This retrospective multicenter study aimed to evaluate the survival benefit of upfront cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (RCC) patients stratified by International Metastatic RCC Database Consortium (IMDC) risk criteria. METHODS: We reviewed the medical records in the Michinoku Database between 2008 and 2019. Patients who received upfront CN, systemic therapy without CN (no CN) and CN after drug therapy (deferred CN) were analyzed. To exclude selection bias due to patient characteristics, baseline clinical data were adjusted by inverse probability of treatment weighting (IPTW). Overall survival (OS) was compared between upfront CN and non-upfront CN (no CN plus deferred CN). Associations between time-varying covariates including systemic therapies and OS stratified by IMDC risk criteria were analyzed by IPTW-adjusted Cox regression method. RESULTS: Of 259 patients who fulfilled the selection criteria, 107 were classified in upfront CN and 152 in non-upfront CN group. After IPTW-adjusted analysis, upfront CN showed survival benefit compared to non-upfront CN in patients with IMDC intermediate risk (median OS: 52.5 versus 31.3 months, p < 0.01) and in patients with IMDC poor risk (27.2 versus 11.4 months, p < 0.01). In IPTW-adjusted Cox regression analysis of time-varying covariates, upfront CN was independently associated with OS benefit in patients with IMDC intermediate risk (hazard ratio 0.52, 95% confidence interval 0.29-0.93, p = 0.03) and in patients with IMDC poor risk (0.26, 0.11-0.59, p < 0.01). CONCLUSIONS: Upfront CN may confer survival benefit in RCC patients with IMDC intermediate and poor risk.

Accompanied by the development of systemic therapy for metastatic renal cell carcinoma, the concept of focal treatment, including surgical treatment, has been changing. Although immediate cytoreductive nephrectomy was essentially considered for synchronous metastatic renal cell carcinoma patients, the CARMENA trial and SURTIME trial revealed the negative impact of immediate cytoreductive nephrectomy. Therefore, immediate cytoreductive nephrectomy is currently considered only for a limited number of patients. Besides, deferred cytoreductive nephrectomy seems to have efficacy for overall survival in prior retrospective studies. Two randomized controlled trials, the PROBE trial (NCT04510597) and the NORDIC-SUN trial (NCT03977571), are underway to elucidate deferred cytoreductive nephrectomy. Metastasectomy is also considered in metastatic renal cell carcinoma patients because previous studies demonstrated the overall survival benefit of metastasectomy. However, since all reports were retrospective studies, physicians could exclude the patients who were not expected to show the efficacy of metastasectomy. Therefore, an adequate patient selection for metastasectomy is important. A common factor predicting better overall survival was complete resection. Radiotherapies for metastatic lesions during systemic therapy showed approximately 90% local disease control rate at 1 year. However, no report has demonstrated that radiotherapy improves survival so far. Since surgical and focal treatments for metastatic renal cell carcinoma patients generally have minimal evidence, further investigations are needed.

OBJECTIVES: We evaluated whether the treatment history of low-dose rituximab affected safety profiles, and humoral and cellular responses induced by severe acute respiratory syndrome coronavirus 2 messenger ribonucleic acid vaccine in healthy controls and kidney transplant recipients. METHODS: We enrolled 10 healthcare workers as controls, 22 kidney transplant recipients with rituximab, and 36 kidney transplant recipients without rituximab without history of coronavirus disease 2019 who received two doses of vaccine. We assessed anti-severe acute respiratory syndrome coronavirus 2 spike antibody and the antigen-specific T cells using enzyme-linked immunospot against spike protein at baseline and after two doses of vaccine. RESULTS: All controls showed anti-severe acute respiratory syndrome coronavirus 2 antibody seroconversion and enzyme-linked immunospot positivity. Only 19/58 (33%) kidney transplant recipients experienced anti-severe acute respiratory syndrome coronavirus 2 antibody seroconversion and 31/58 (53%) kidney transplant recipients developed enzyme-linked immunospot assay positivity after vaccination. The anti-severe acute respiratory syndrome coronavirus 2 antibody seroconversion rate and enzyme-linked immunospot assay positivity rate after vaccination were not significantly different between kidney transplant recipients with or without rituximab. Multivariate regression analysis demonstrated rituximab was not associated with a lack of humoral and cellular responses to the vaccine. CONCLUSIONS: Low-dose rituximab in kidney transplant recipients did not affect humoral or cellular responses to the severe acute respiratory syndrome coronavirus 2 messenger ribonucleic acid vaccine without severe systemic adverse events including the deterioration of kidney function.

(1) Background: Extracellular signal-regulating kinase 5 (ERK5) has been implicated in many cellular functions, including survival, proliferation, and vascularization. Our objectives were to examine the expression and effect of ERK5 in clear cell renal cell carcinoma (ccRCC). (2) Methods: The expressions of ERK5 and its regulating micro-RNA miR-143 were investigated using immunohistochemistry and quantitative reverse transcriptase PCR in surgical specimens of ccRCC patients. With invitro and in vivo studies, we used pharmacologic ERK5 inhibitor XMD8-92, RNA interference, pre-miR-143 transduction, Western blotting, MTS assay, apoptosis assay, and subcutaneous xenograft model. (3) Results: A strong ERK5 expression in surgical specimen was associated with high-grade (p = 0.01), high-recurrence free rate (p = 0.02), and high cancer-specific survival (p = 0.03). Expression levels of ERK5 and miR-143 expression level were correlated (p = 0.049). Pre-miR-143 transduction into ccRCC cell A498 suppressed ERK5 expression. ERK5 inhibition enhanced cyclin-dependent kinase inhibitor p21 expression and decreased anti-apoptotic molecules BCL2, resulting in decreased cell proliferation and survival both in ccRCC and endothelial cells. In the xenograft model, ERK5 inhibitor XMD8-92 suppressed tumor growth. (4) Conclusions: ERK5 is regulated by miR-143, and ERK5 inhibition is a promising target for ccRCC treatment.

The use of immune checkpoint inhibitors to treat urothelial carcinoma (UC) is increasing rapidly without clear guidance for validated risk stratification. This multicenter retrospective study collected clinicopathological information on 463 patients, and 11 predefined variables were analyzed to develop a multivariate model predicting overall survival (OS). The model was validated using an independent dataset of 292 patients. Patient characteristics and outcomes were well balanced between the discovery and validation cohorts, which had median OS times of 10.2 and 12.5 mo, respectively. The final validated multivariate model was defined by risk scores based on the hazard ratios (HRs) of independent prognostic factors including performance status, site of metastasis, hemoglobin levels, and the neutrophil-to-lymphocyte ratio. The median OS times (95% confidence intervals [CIs]) for the low-, intermediate-, and high-risk groups (discovery cohort) were not yet reached (NYR) (NYR-19.1), 6.8 mo (5.8-8.9), and 2.3 mo (1.2-2.6), respectively. The HRs (95% CI) for OS in the low- and intermediate-risk groups vs the high-risk group were 0.07 (0.04-0.11) and 0.23 (0.15-0.37), respectively. The objective response rates for in the low-, intermediate-, and high-risk groups were 48.3%, 28.8%, and 10.5%, respectively. These differential outcomes were well reproduced in the validation cohort and in patients who received pembrolizumab after perioperative or first-line chemotherapy (N = 584). In conclusion, the present study developed and validated a simple prognostic model predicting the oncological outcomes of pembrolizumab-treated patients with chemoresistant UC. The model provides useful information for external validation, patient counseling, and clinical trial design.

BACKGROUND: We performed subgroup analyses of the AFTER I-O study to clarify the association of time-to-treatment failure (TTF) and discontinuation reason of prior immune-oncology (I-O) therapy, and molecular targeted therapy (TT) regimen with the outcomes of TT after I-O. METHODS: The data of Japanese metastatic renal cell carcinoma patients treated with TT after nivolumab (NIVO) (CheckMate 025) or NIVO + ipilimumab (IPI) (CheckMate 214) were retrospectively analyzed. The objective response rates (ORRs), progression-free survival (PFS) and overall survival (OS) of TT after I-O were analyzed by subgroups: TTF (<6 or ≥6 months) and discontinuation reason of prior I-O (progression or adverse events), and TT regimen (sunitinib or axitinib). We also analyzed PFS2 of prior I-O and OS from first-line therapy. RESULTS: The ORR and median PFS of TT after NIVO and NIVO+IPI among the subgroups was 17-36% and 20-44%, and 7.1-11.6 months and 16.3-not reached (NR), respectively. The median OS of TT after NIVO was longer in patients with longer TTF of NIVO and treated with axitinib. Conversely, median OS of TT after NIVO+IPI was similar among subgroups. The median PFS2 of NIVO and NIVO+IPI was 36.7 and 32.0 months, respectively. The median OS from first-line therapy was 70.5 months for patients treated with NIVO and NR with NIVO+IPI. The safety profile of each TT after each I-O was similar to previous reports. CONCLUSIONS: The efficacy of TT after NIVO or NIVO+IPI was favorable regardless of the TTF and discontinuation reason of prior I-O, and TT regimen.

OBJECTIVES: Guidelines for treatment of mRCC recommend nivolumab monotherapy (NIVO) for treated patients, and nivolumab plus ipilimumab combination therapy (NIVO+IPI) for untreated IMDC intermediate and poor-risk mRCC patients. Although molecular-targeted therapies (TTs) such as VEGFR-TKIs and mTORi are recommended as subsequent therapy after NIVO or NIVO+IPI, their efficacy and safety remain unclear. METHODS: Outcome of Japanese patients with mRCC who received TT after NIVO (CheckMate 025) or NIVO+IPI (CheckMate 214) were retrospectively analyzed. Primary endpoints were investigator-assessed ORR of the first TT after either NIVO or NIVO+IPI. Secondary endpoints included TFS, PFS, OS and safety of TTs. RESULTS: Twenty six patients in CheckMate 025 and 19 patients in CheckMate 214 from 20 centers in Japan were analyzed. As the first subsequent TT after NIVO or NIVO+IPI, axitinib was the most frequently treated regimen for both CheckMate 025 (54%) and CheckMate 214 (47%) patients. The ORRs of TT after NIVO and NIVO+IPI were 27 and 32% (all risks), and median PFSs were 8.9 and 16.3 months, respectively. During the treatment of first TT after either NIVO or NIVO+IPI, 98% of patients experienced treatment-related adverse events, including grade 3-4 events in 51% of patients, and no treatment-related deaths occurred. CONCLUSIONS: TTs have favorable antitumor activity in patients with mRCC after ICI, possibly via changing the mechanism of action. Safety signals of TTs after ICI were similar to previous reports. These results indicate that sequential TTs after ICI may contribute for long survival benefit.

BACKGROUND: Arteriovenous fistula (AVF) is the most preferred vascular access for hemodialysis patients, and early failure of AVF is one of the most avoidable complications of this procedure. We retrospectively evaluated whether adjuvant systemic heparinization just before arterial manipulation could reduce early failure of primary AVF. METHODS: Three hundred and fifty-six patients with end-stage renal failure who underwent primary AVF surgery from April 2009 to September 2020 were enrolled in this study. The patients were divided into two groups based on whether they received adjuvant heparinization or not. Patient backgrounds, frequency of early AVF failure, and bleeding events were compared between the two groups. Multivariate Cox regression analysis identified risk factors for early AVF failure. RESULTS: Early failure of AVF was observed in only 2 of 157 patients (1.2%) in the adjuvant group, and the incident was significantly lower than observed in the non-adjuvant group, i.e., 17 of 199 patients (8.5%) (p = 0.002). Bleeding events were not significantly different between the two groups. Seven of 157 patients (4.5%) in the adjuvant group and 7 of 199 patients (3.5%) in the non-adjuvant group experienced bleeding events (p = 0.785). Female sex, use of steroids, hypoalbuminemia, venous stenosis in pre-surgical evaluation, arterial spasm in the perioperative period, new-onset venous stenosis after AVF anastomosis, technical failure of surgery, no early cannulation after surgery, and non-adjuvant heparinization were related to early AVF failure in the multivariate regression analysis. CONCLUSION: Adjuvant systemic heparinization therapy just before arterial manipulation reduced early failure of primary AVF without increasing bleeding events.

BACKGROUND: The aims of this study were to investigate prognosis and validate prognostic models [Memorial Sloan-Kettering Cancer Center (MSKCC), International Metastatic Renal Cell Carcinoma Data Consortium (IMDC), and Japanese metastatic renal cancer (JMRC) models] in the targeted therapy era in Japanese patients with metastatic renal cell carcinoma. METHODS: We retrospectively analyzed 692 patients who were diagnosed with mRCC from January 2008 to August 2018 in the Michinoku Japan Urological Cancer Study Group database. Nivolumab as sequential therapy was widely used. Other immune checkpoint inhibitors were excluded from this study. RESULTS: The median overall survival (95% confident interval) in all, MSKCC favorable, intermediate, and poor risk patients was 41.0 months (33.9-46.8), not reached (63.5 to not estimable), 46.8 months (37.1-52.9), and 10.4 months (8.9-14.4), respectively. The median overall survival (95% confident interval) in IMDC favorable, intermediate, and poor risk patients was not reached (61.6 to not estimable), 47.4 months (41.4-56.5), and 11.5 (9.9-16.3), respectively. The c-index of the MSKCC, IMDC, and JMRC models calculated at mRCC diagnosis was 0.680, 0.689, and 0.700, respectively. No statistical differences were found in the c-index among the models. CONCLUSION: While the real-world overall survival in Japanese patients with mRCC in the targeted therapy era improved compared to that previously reported in the cytokine era, there was no clear difference in the survival of poor risk patients between these eras. There were no differences in the superiority among the models.

OBJECTIVES: The utility of brain metastasis screening in asymptomatic metastatic renal cell carcinoma is controversial. Our study evaluated the utility of routine head computed tomography during systemic therapy. METHODS: We retrospectively investigated 152 metastatic renal cell carcinoma patients who did not initially have brain metastasis at Yamagata University Hospital from January 2008 to July 2019. Patients who routinely received head computed tomography scan together with routine contrast-enhanced chest/abdominal/pelvic computed tomography scan every 2-4 months during systemic therapy ("Routine head computed tomography" group, n = 95) and patients without routine head computed tomography ("No routine head computed tomography" group, n = 57) were compared. RESULTS: Brain metastasis occurred in 16 patients in the "Routine head computed tomography" group and six patients in the "No routine head computed tomography" group. There was no statistical difference in overall survival after metastatic renal cell carcinoma diagnosis between groups (53.4 vs 37.3 months, respectively, P = 0.357) and neurological symptom-free survival after metastatic renal cell carcinoma diagnosis (53.4 vs 36.6 months, P = 0.336). Although there was no statistical difference on incidence of unrecovered neurological symptom (25.0% vs 50.0%, P = 0.334), fewer patients in the "Routine head computed tomography" group required craniotomy (0% vs 66.7%, P = 0.002). In the "No routine head computed tomography" group, the neurological symptom resolved for all patients without craniotomy. CONCLUSIONS: Routine head computed tomography during systemic therapy for metastatic renal cell carcinoma is not significantly associated with improved brain metastasis prognosis. However, routine head computed tomography enables brain metastasis diagnosis in the asymptomatic phase, which can avoid craniotomy.

OBJECTIVES: To compare overall survival between patients with metastatic renal cell carcinoma treated by cytoreductive nephrectomy and those not treated by cytoreductive nephrectomy. METHODS: We retrospectively evaluated 278 patients with metastatic renal cell carcinoma treated with first-line tyrosine kinase inhibitors between January 2008 and November 2019. Patients were divided into two groups: a cytoreductive nephrectomy group (immediate or deferred cytoreductive nephrectomy) and a group who received systemic tyrosine kinase inhibitor therapies alone without cytoreductive nephrectomy (control group). Overall survival comparisons were made in all patients in the control versus the cytoreductive nephrectomy group, the control versus the immediate cytoreductive nephrectomy group, the control versus the deferred cytoreductive nephrectomy group, and the deferred cytoreductive nephrectomy versus the immediate cytoreductive nephrectomy group. Analyses were weighted using the propensity score-based inverse probability of treatment weighting method to adjust for group imbalances. RESULTS: The median (range) age of the patients was 65 (59-73) years. Of the 278 patients, 132 and 146 were in the control group and the cytoreductive nephrectomy (immediate, n = 107 and deferred, n = 39) group, respectively. A significant difference was noted between the control and cytoreductive nephrectomy groups in age, clinical stage, International Metastatic Renal Cell Carcinoma Database Consortium risk factors, and the number of metastatic sites. Inverse probability of treatment weighting-adjusted Cox regression analysis showed a significant difference in overall survival between the control and the cytoreductive nephrectomy groups and between the control and the immediate or deferred cytoreductive nephrectomy groups. However, there was no significant difference in overall survival between the immediate and the deferred cytoreductive nephrectomy groups. CONCLUSIONS: Our findings suggest that metastatic renal cell carcinoma patients undergoing cytoreductive nephrectomy are more likely to have longer overall survival than those who receive tyrosine kinase inhibitor therapy only.

BACKGROUND: The decline of health-related quality-of-life (QOL) during the year after radical prostatectomy is severe. General self-efficacy (GSE) is an effective psychological factor for long-term regulation of patient behavior and emotions. GSE is expected to facilitate enhanced health-related quality of life. We evaluated changes in GSE and analyzed the relationship between GSE and prostate cancer-specific and general health-related QOL. METHODS: We conducted a longitudinal survey with 104 patients who underwent radical prostatectomy and administered the General Self-efficacy Scale (GSES), Expanded Prostate Cancer Index Composite (EPIC), and SF8 Health Survey (SF-8). ANCOVA was performed to compare EPIC and SF-8 between GSES high and low-medium groups. RESULTS: GSES scores increased significantly after 6 months. Regarding EPIC urinary summary scores, high GSES group was significantly higher than low-medium group at 1 month (mean score difference [MSD], 7.3; 95% CI 1.1-13.2, P = 0.016), 3 months (MSD, 6.8; 95% CI 0.7-12.8, P = 0.028), and 6 months (MSD, 6.3; 95% CI 0.9-11.7, P = 0.022). High GSES group had significantly higher SF-8 physical component summary score at 6 months (MSD, 3.2; 95% CI 1.4-5.0, P = 0.001), and significantly higher SF-8 mental component summary score at 1 month (MSD, 2.6; 95% CI 0.4-4.9, P = 0.022), 3 months (MSD, 2.7; 95% CI 0.8-4.6, P = 0.007), and 6 months (MSD, 2.8; 95% CI 1.0-4.6, P = 0.003). CONCLUSION: This study suggests that high GSE was associated with better prostate cancer-specific and general health-related QOL after radical prostatectomy.
