Cross-sectional and longitudinal analyses of urinary extracellular vesicle mRNA markers in urothelial bladder cancer patients. Sci Rep 2024; 14:6801. [PMID: 38514751 PMCID: PMC10957914 DOI: 10.1038/s41598-024-55251-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Accepted: 02/21/2024] [Indexed: 03/23/2024] Open
Abstract
We designed this multi-center prospective study with the following objectives: (1) the cross-sectional validation of extracellular vesicles (EV) mRNA markers to detect urothelial bladder cancer (UBC) before transurethral resection of bladder cancer (TURBT), and (2) the longitudinal validation of EV mRNA markers to monitor non-muscle invasive bladder cancer (NMIBC) recurrence after TURBT. EV mRNA markers evaluated in this study were KRT17, GPRC5A, and SLC2A1 in addition to two additional markers from literatures, MDK and CXCR2, and measured by quantitative RT-PCR with normalization by a reference gene (ALDOB). Diagnostic performances of EV mRNA markers were compared to conventional markers. Regarding the first objective, we confirmed that EV mRNA biomarkers in urine were higher in UBC patients, particularly those with higher stage/grade tumors, than in those without UBC (n = 278 in total) and the diagnostic performance of EV mRNA MDK and KRT17 outperformed conventional biomarkers with AUC 0.760 and 0.730, respectively. Concerning the second objective, we prospectively analyzed the time courses of EV mRNA markers while NMIBC patients (n = 189) (median follow-up 19 months). The expression of EV mRNA KRT17 was significantly high in patients with recurrence, while it gradually decreased over time in those without recurrence (p < 0.01).

Effects of empagliflozin on progression of chronic kidney disease: a prespecified secondary analysis from the empa-kidney trial. Lancet Diabetes Endocrinol 2024; 12:39-50. [PMID: 38061371 PMCID: PMC7615591 DOI: 10.1016/s2213-8587(23)00321-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Impact of primary kidney disease on the effects of empagliflozin in patients with chronic kidney disease: secondary analyses of the EMPA-KIDNEY trial. Lancet Diabetes Endocrinol 2024; 12:51-60. [PMID: 38061372 DOI: 10.1016/s2213-8587(23)00322-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Quality improvement in managing patients with non-muscle-invasive bladder cancer by introducing a surgical checklist for transurethral resection of bladder tumor. PLoS One 2022; 17:e0276816. [PMID: 36301957 PMCID: PMC9612454 DOI: 10.1371/journal.pone.0276816] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Accepted: 10/13/2022] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND The quality of transurethral resection of bladder tumor (TURBT) markedly varies among surgeons and may have a considerable impact on treatment outcomes. The importance of a surgical checklist for TURBT has been suggested in order to standardize the procedure and improve surgical and oncological outcomes. In the present study, we verified the usefulness of a checklist for managing patients with non-muscle-invasive bladder cancer (NMIBC). METHODS This retrospective study included 201 NMIBC patients diagnosed with Ta, T1, or Tis between October 2011 and February 2021. After September 2016, TURBT was performed with a checklist. We analyzed the intravesical recurrence-free survival (RFS) rate and the presence or absence of the detrusor muscle in resected specimens before and after the introduction of the checklist. Survival rates were compared using the Log-rank test. A multivariate analysis with Cox proportional hazards modeling was performed to verify risk factors for intravesical recurrence. RESULTS Ninety-nine patients who underwent TURBT with the checklist (checklist group) were compared with 102 patients who underwent TURBT without the checklist (non-checklist group). When the analysis was narrowed down to 9 critical items, we observed a mean number of 9 documented items per operative report (98.0% completion) after implementation of the checklist. Two-year intravesical RFS rates in the checklist and non-checklist groups were 76.7 and 69.5%, respectively (p = 0.1059). The Cox proportional multivariate analysis showed that the rate of intravesical recurrence was slightly lower in the checklist group (hazard ratio 0.7376, 95% CI 0.4064-1.3388, P = 0.3170). CONCLUSION The introduction of a checklist is recommended for the standardization of TURBT and increasing the quality of operative reporting, and it may also improve oncological outcomes.

Immune-related adverse events in urothelial cancer patients: Adjustment for immortal time bias. Cancer Sci 2022; 113:3912-3921. [PMID: 35997546 PMCID: PMC9633286 DOI: 10.1111/cas.15539] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 08/03/2022] [Accepted: 08/08/2022] [Indexed: 12/01/2022] Open
Abstract
To investigate the association between the onset, severity, and type of immune‐related adverse events (irAEs) and the efficacy of pembrolizumab in patients with platinum‐pretreated advanced urothelial carcinoma (UC), we retrospectively collected clinical datasets of 755 patients and conducted landmark analysis. Patients who survived for fewer than 3 months were excluded from the evaluation to reduce the immortal time bias. In total, 620 patients were evaluated, of whom 220 patients (35.5%) experienced grade ≥2 irAEs, including 134 patients with grade 2 irAEs and 86 with grade ≥3 irAEs. Propensity score matching extracted 198 patients with and without grade ≥2 irAEs. The onset of grade ≥2 irAEs was associated with longer median progression‐free survival (PFS) (8.3 months vs. 4.5 months, p = 0.003) and overall survival (OS) (20.4 months vs. 14.3 months, p = 0.031) and a higher objective response rate (ORR) (44.8% vs. 30.2%, p = 0.004). Patients with grade 2 irAEs had significantly better oncological outcomes (PFS, OS, and ORR) than grade ≤1 and ≥3 irAEs. Patients with grade ≥3 irAEs had worse outcomes than grade 2 irAEs. Endocrine and skin irAEs were related with better survival outcomes, and the rate of severities was lower in these categories. In conclusion, the occurrence of irAEs, particularly low‐grade irAEs, was predictive of pembrolizumab efficacy in patients with platinum‐pretreated advanced UC.

Impact of adherence to criteria on oncological outcomes of radical prostatectomy in patients opting for active surveillance: data from the PRIAS-JAPAN study. Jpn J Clin Oncol 2022; 52:1056-1061. [PMID: 35662340 DOI: 10.1093/jjco/hyac092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Accepted: 05/13/2022] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES This study aimed to evaluate whether oncological outcomes of radical prostatectomy differ depending on adherence to the criteria in patients who opt for active surveillance. MATERIALS AND METHODS We retrospectively reviewed the data of 1035 patients enrolled in a prospective cohort of the PRIAS-JAPAN study. After applying the exclusion criteria, 136 of 162 patients were analyzed. Triggers for radical prostatectomy due to pathological reclassification on repeat biopsy were defined as on-criteria. Off-criteria triggers were defined as those other than on-criteria triggers. Unfavorable pathology on radical prostatectomy was defined as pathological ≥T3, ≥GS 4 + 3 and pathological N positivity. We compared the pathological findings on radical prostatectomy and prostate-specific antigen recurrence-free survival between the two groups. The off-criteria group included 35 patients (25.7%), half of whom received radical prostatectomy within 35 months. RESULTS There were significant differences in median prostate-specific antigen before radical prostatectomy between the on-criteria and off-criteria groups (6.1 vs. 8.3 ng/ml, P = 0.007). The percentage of unfavorable pathologies on radical prostatectomy was lower in the off-criteria group than that in the on-criteria group (40.6 vs. 31.4%); however, the differences were not statistically significant (P = 0.421). No significant difference in prostate-specific antigen recurrence-free survival was observed between the groups during the postoperative follow-up period (median: 36 months) (log-rank P = 0.828). CONCLUSIONS Half of the off-criteria patients underwent radical prostatectomy within 3 years of beginning active surveillance, and their pathological findings were not worse than those of the on-criteria patients.

Abstract
250 Background: Trigger for definitive treatment in active surveillance (AS) is strictly criteria-based, but some patients might be surgically treated without adherence to the criteria. We aimed to evaluate whether oncological outcomes differ depending on adherence to the criteria in patients who opting for AS. Methods: We retrospectively reviewed data of 1,035 patients enrolled in a prospective cohort of PRIAS-JAPAN. Of 162 patients underwent radical prostatectomy, 136 patients were analyzed, excluding those with Gleason score 3+4 at diagnosis, RP within one year of enrollment. Triggers for RP due to pathological reclassification on repeat biopsy was defined as on-criteria. We compared pathological findings on RP and prostate specific antigen (PSA) recurrence-free survival of on-criteria with off-criteria. Results: Off-criteria was 35 patients (24.7%). There were significant differences in the median time to RP (16 vs. 18.5 months, p<0.001) and median PSA before RP (6.1 vs. 8.3 ng/mL, p=0.007) when comparing patients with on-criteria and off-criteria. Fifty percent of off-criteria received RP within 35 months. On pathological findings of RP, pathological T3≤ (10.5 vs. 9.4%, p=0.183), Gleason score 4+3≤ (33 vs. 28.6%, p=0.679), and pathological N positive (4.3 vs. 0%, p>0.999) were not significantly different. At a median postoperative follow-up of 36 months, no significant difference in PSA recurrence-free survival was found (log-rank p = 0.828). Conclusions: Although half of off-criteria patients underwent RP within 3 years of starting AS, their oncological outcomes were not different from on-criteria. Our result suggested the potential for tailoring the inclusion criteria of AS within the strict protocol. Clinical trial information: 000002874. [Table: see text]

Outcomes of bacillus Calmette-Guérin therapy without a maintenance schedule for high-risk non-muscle-invasive bladder cancer in the second transurethral resection era. Int J Urol 2021; 29:251-258. [PMID: 34894009 PMCID: PMC9299795 DOI: 10.1111/iju.14761] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2021] [Accepted: 11/18/2021] [Indexed: 11/27/2022]
Abstract
Objectives We examined the outcomes of eight weekly bacillus Calmette–Guérin induction therapy after second transurethral resection, and investigated risk factors for intravesical recurrence or disease progression in high‐risk non‐muscle‐invasive bladder cancer patients. Methods This retrospective study included 146 high‐risk non‐muscle‐invasive bladder cancer patients who received eight weekly bacillus Calmette–Guérin instillations without a maintenance schedule between 2000 and 2019. Intravesical recurrence‐free and progression‐free survival rates were evaluated using the Kaplan–Meier method. The Cox proportional hazards model was used to identify risk factors. Results Pathological T staging in the first transurethral resection was pTa in 56 patients (38.4%), pT1 in 75 (51.4%) and primary carcinoma in situ in 15 (10.2%). A total of 109 (83.2%) with pTa–1 disease underwent second transurethral resection before bacillus Calmette–Guérin induction therapy, and residual disease was detected in 54 (49.5%). The completion rate of eight instillations was 82.2%. The 2‐ and 5‐year intravesical recurrence‐free survival rates were 80.7% and 75.2%, whereas the 2‐ and 5‐year progression‐free survival rates were 85.7% and 82.0%. Recurrent tumors (hazard ratio 6.5830, P = 0.0007) and residual tumors at the second transurethral resection (hazard ratio 4.0337, P = 0.0021) were risk factors for intravesical recurrence. Multiple tumors (hazard ratio 5.8056, P = 0.0302), pT1 disease (hazard ratio 3.7351, P = 0.0447) and residual tumors at second transurethral resection (hazard ratio 3.2552, P = 0.0448) were associated with disease progression. Conclusions Accurate disease staging and disease elimination by second transurethral resection followed by eight weekly bacillus Calmette–Guérin instillations achieved good disease control. Our protocol (without a maintenance schedule) after thorough surgical resection has potential as a treatment option in the current bacillus Calmette–Guérin shortage.

Pre-pembrolizumab neutrophil-to-lymphocyte ratio (NLR) predicts the efficacy of second-line pembrolizumab treatment in urothelial cancer regardless of the pre-chemo NLR. Cancer Immunol Immunother 2021; 71:461-471. [PMID: 34235546 DOI: 10.1007/s00262-021-03000-8] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Accepted: 06/28/2021] [Indexed: 12/18/2022]
Abstract
Neutrophil-to-lymphocyte ratio (NLR) was reported to be associated with prognosis of urothelial cancer (UC) patients receiving systemic chemotherapy or immunotherapy. However, it has not been elucidated how preceding first-line chemotherapy affects NLR and subsequent second-line pembrolizumab treatment. This multicenter study analyzed 458 patients with metastatic UC who received first-line chemotherapy and second-line pembrolizumab with regard to pre-chemotherapy and pre-pembrolizumab NLR in association with the efficacy of chemotherapy and pembrolizumab treatment. NLR was increased in 47% while decreased in 53% of patients before and after first-line chemotherapy. High pre-chemotherapy NLR (≥ 3) was significantly associated with unfavorable overall (OS, P = 0.0001) and progression-free (P < 0.0001) survivals after first-line chemotherapy. However, pre-chemotherapy NLR showed only modest influence on radiological response and survival after second-line pembrolizumab treatment, whereas pre-pembrolizumab NLR showed higher association. NLR decrease was associated with partial response or greater objective response by first-line chemotherapy, while NLR increase was associated with higher patient age. In conclusion, immediate pre-chemotherapy and pre-pembrolizumab NLR was significantly associated with efficacy of the following treatment, respectively. However, even patients with high pre-chemotherapy NLR achieved favorable OS if they had their NLR reduced by chemotherapy, whereas those with high pre-chemotherapy NLR yielded unfavorable OS if they had their NLR remained high after chemotherapy, suggesting that chemotherapy may have differential effect on the efficacy of subsequent pembrolizumab treatment in UC patients.

Abstract
BACKGROUND We used real-world and large-scale data to assess the clinical efficacy and safety of pembrolizumab in older patients with advanced urothelial carcinoma (UC). METHODS A total of 608 patients who received pembrolizumab for the treatment of chemoresistant UC were retrospectively analyzed. All patients were histologically diagnosed with pure UC. Using propensity score matching (PSM) (ECOG performance status, site of metastasis, hemoglobin level and neutrophil-to-lymphocyte ratio, 1:1 matching), the overall survival (OS) and adverse events (AEs) of patients <75 and ≥75 years old were compared. RESULTS The median follow-up (IQR) period was 16.1 (9.9-20.5) months. After PSM, there were 215 patients each in the aged <75 years and aged ≥75-year-old groups. The median OS of all patients was estimated to be 10.4 months (95% confidence interval [CI] = 8.8-12.1). After PSM, the median OS was 7.8 months (95% CI = 5.2-10.4) in the <75-year-old group and 10.4 months (95% CI = 7.3-13.5) in the ≥75-year-old group (P = 0.186). Any-grade AEs were more frequently reported in the ≥75-year-old group in comparison to the age <75-year-old group (55.3% vs. 41.9%, P = 0.007), whereas there was no significant difference between the two groups in the incidence of grade ≥3 AEs (10.2% vs. 12.6%, P = 0.544). The objective response rate, defined as complete remission or a partial response, was 22.8% in the <75-year-old group and 25.1% in the ≥75-year-old group (P = 0.651). CONCLUSIONS The present study demonstrates that age does not affect the efficacy and safety of pembrolizumab treatment for advanced chemoresistant UC. Pembrolizumab treatment should not be avoided based on chronological age; however, close monitoring for the development of treatment-related AE should be considered for older patients.

Impact of health-related quality of life on repeat protocol biopsy compliance on active surveillance for favorable prostate cancer: results from a prospective cohort in the PRIAS-JAPAN study. Urol Oncol 2021; 40:56.e9-56.e15. [PMID: 34112576 DOI: 10.1016/j.urolonc.2021.05.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 03/25/2021] [Accepted: 05/02/2021] [Indexed: 11/17/2022]
Abstract
OBJECTIVES This study aimed to evaluate how health-related quality of life (HRQOL) is related to repeat protocol biopsy compliance. MATERIALS AND METHODS We conducted a retrospective analysis using data from a prospective cohort in the Prostate Cancer Research International: Active Surveillance (PRIAS)-JAPAN study between January 2010 and August 2019. We used the Short Form 8 Health Survey (SF-8), as patient-reported outcomes, to assess HRQOL at AS enrollment and the first year of the protocol. The physical component summary (PCS) and mental component summary (MCS) were calculated from SF-8 questionnaires. The primary outcome was the evaluation of the association of HRQOL at enrollment on the first repeat biopsy compliance. The secondary outcome was the comparison of SF-8 scores during AS, stratified by repeat protocol biopsy compliance. RESULTS Of 805 patients who proceeded to the first year of the protocol, the non-compliance rate was 15% (121 patients). In the adjusted model, lower MCS at enrollment was significantly associated with the first repeat protocol biopsy non-compliance (odds ratio [OR], 2.134; 95% confidence interval [CI], 1.031-4.42; P = 0.041) but not in lower PCS (OR, 0.667; 95% CI, 0.294-1.514; P = 0.333). All subscales of SF-8 were lower in the non-compliance group than in the compliance group at any point. MCS in the non-compliance group improved over time from the time of AS enrollment (2.34 increased, P = 0.152). CONCLUSION Our data suggest that lower MCS at AS enrollment using patient-reported outcomes was negatively associated with the first repeat protocol biopsy compliance. Our study may support the availability of a simple questionnaire to extract non-compliance.

The updated outcomes of bladder-preserving trimodal therapy using a real-time tumor-tracking radiotherapy system for patients with muscle-invasive bladder cancer. Jpn J Clin Oncol 2020; 50:609-616. [PMID: 31955206 PMCID: PMC7202139 DOI: 10.1093/jjco/hyz211] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2019] [Revised: 10/13/2019] [Accepted: 12/20/2019] [Indexed: 11/14/2022] Open
Abstract
Objective Bladder-preserving trimodal therapy is recognized as a promising alternative treatment for muscle-invasive bladder cancer. We report the updated outcomes of muscle-invasive bladder cancer patients that were treated using our treatment protocol, which involves radiotherapy delivered with a real-time tumor-tracking radiotherapy system. Methods Thirty-eight patients who were diagnosed with T2-T4N0M0 bladder cancer between 1998 and 2016 and had clinically inoperable disease or refused to undergo surgery were enrolled. The treatment protocol included maximal transurethral resection followed by whole-bladder radiotherapy (40 Gy). Concurrent nedaplatin-based chemotherapy was administered to patients with adequate renal function. At the time of the first evaluation (via transurethral resection of the tumor bed), fiducial markers were endoscopically inserted into the bladder wall around the tumor. A boost of 25 Gy was administered using the real-time tumor-tracking radiotherapy system. The second evaluation (via transurethral resection of the tumor bed) was performed 6 months after the start of treatment. The Kaplan–Meier method and Cox hazards analysis were used to analyze overall survival and cancer-specific survival. Results The median duration of the follow-up period was 28 months (range: 3–161 months). The 5- and 10-year overall survival rates were 54.9 and 41.2%, respectively. Twenty-five (65.8%) and twenty (74.1%) patients had achieved complete responses to chemoradiation at the first and second evaluations, respectively. In univariate and multivariate analyses, performance status was found to be significantly associated with overall survival [P = 0.03, hazard ratio: 3.48, 95% confidence interval: 1.15–10.6] and cancer-specific survival [P = 0.02, hazard ratio: 4.57, 95% confidence interval: 1.32–16.9], and sex was shown to be significantly associated with cancer-specific survival [P = 0.03, hazard ratio: 3.07, 95% confidence interval: 1.09–8.30]. Conclusions Our bladder-preserving trimodal therapy protocol, which involves the use of a real-time tumor-tracking radiotherapy system, produced an acceptable overall survival rate. This therapy is a reasonable alternative for patients that are medically unfit for or do not want to undergo cystectomy.

Abstract
Tumor endothelial cells (TEC) lining tumor blood vessels actively contribute to tumor progression and metastasis. In addition to tumor cells, TEC may develop drug resistance during cancer treatment, allowing the tumor cells to survive chemotherapy and metastasize. We previously reported that TECs resist paclitaxel treatment via upregulation of ABCB1. However, whether TEC phenotypes are altered by anticancer drugs remains to be clarified. Here, we show that ABCB1 expression increases after chemotherapy in urothelial carcinoma cases. The ratio of ABCB1-positive TEC before and after first-line chemotherapy in urothelial carcinoma tissues (n = 66) was analyzed by ABCB1 and CD31 immunostaining. In 42 cases (64%), this ratio increased after first-line chemotherapy. Chemotherapy elevated ABCB1 expression in endothelial cells by increasing tumor IL8 secretion. In clinical cases, ABCB1 expression in TEC correlated with IL8 expression in tumor cells after first-line chemotherapy, leading to poor prognosis. In vivo, the ABCB1 inhibitor combined with paclitaxel reduced tumor growth and metastasis compared with paclitaxel alone. Chemotherapy is suggested to cause inflammatory changes in tumors, inducing ABCB1 expression in TEC and conferring drug resistance. Overall, these findings indicate that TEC can survive during chemotherapy and provide a gateway for cancer metastasis. Targeting ABCB1 in TEC represents a novel strategy to overcome cancer drug resistance. SIGNIFICANCE: These findings show that inhibition of ABCB1 in tumor endothelial cells may improve clinical outcome, where ABCB1 expression contributes to drug resistance and metastasis following first-line chemotherapy.

Abstract
OBJECTIVES This study investigated the relapse pattern and oncologic outcomes after laparoscopic nephroureterectomy with template-based lymph node dissection (LND) in patients with clinically node-negative (cN0) upper urinary tract urothelial carcinoma. The frequency of lymph node metastasis, including micrometastases, was also evaluated. METHODS AND MATERIALS A total of 105 patients with cTa-3N0M0 upper urinary tract urothelial carcinoma were analyzed, all of whom underwent regional LND during laparoscopic nephroureterectomy. Of those patients, 96 (91%) underwent complete LND in accordance with an anatomical template-based rule. We collected patient characteristics, pathological data, and follow-up data from medical charts. Micrometastases were assessed by pan-cytokeratin immunohistochemistry. Nonurothelial recurrence-free survival and cancer-specific survival were estimated using the Kaplan-Meier method. RESULTS The median number of lymph nodes removed was 12 (range, 1-59). Lymph node metastasis was identified by routine pathological examination in 7 (7/105, 6.7%) patients. Pan-cytokeratin immunohistochemistry revealed micrometastases in 5 additional patients (pNmicro +: 5/105, 4.8%). Nonurothelial disease recurrence was observed in 21 (20%) patients at a median of 10 months (range: 1-33) after surgery. Distant metastasis was dominant (15/105, 14.3%), followed by locoregional recurrence (5/105, 4.8%) and both (1/105, 0.95%). The 5-year nonurothelial recurrence-free survival rates were 84.8% for pN0, 53.3% for pNmicro+, and 19.1% for pN+ (3-sample log-rank test, P < 0.0001). The 5-year cancer-specific survival rates were 95.0% for pN0, 53.3% for pNmicro+, and 23.8% for pN+ (P < 0.0001). CONCLUSIONS Our observation showed that template-based LND could contribute to precise disease staging and better local disease control probably by eliminating nodal disease, compared with previous studies. The survival impact and ideal management of pNmicro+ disease should be evaluated in a larger cohort.

Abstract
OBJECTIVE The complement cascade, especially the alternative pathway of complement, has been shown in basic research to be associated with anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV). We aimed to elucidate relationships between serum complement components and clinical characteristics in AAV. METHOD In a nationwide prospective cohort study (RemIT-JAV-RPGN), we measured the serum levels of C1q, C2, C3, C3b/iC3b, C4, C4b, C5, C5a, C9, factor B, factor D, factor H, factor I, mannose-binding lectin, and properdin in 52 patients with microscopic polyangiitis (MPA) and 39 patients with granulomatosis with polyangiitis (GPA). RESULTS The properdin level of MPA and GPA was significantly lower than that of healthy donors. The properdin level was negatively correlated with the Birmingham Vasculitis Activity Score (BVAS) (ρ = -0.2148, p = 0.0409). The factor D level at 6 months was significantly positively correlated with the Vasculitis Damage Index (VDI) at 6, 12, and 24 months (ρ = 0.4207, 0.4132, and 0.3115, respectively). Patients with a higher ratio of C5a to C5 had higher neutrophil percentage and serum immunoglobulin G levels, and significantly lower creatinine levels. Cluster analysis divided the MPA and GPA patients into three subgroups. A principal component (PC) analysis aggregated 15 types of complements into alternative pathway-related PC 1 and complement classical pathway and common pathway-related PC 2. CONCLUSIONS The serum levels of properdin and factor D were correlated with the BVAS and the VDI in MPA and GPA, respectively. Our analyses suggested the pathological heterogeneity of MPA and GPA from the aspect of complement components.

Abstract
OBJECTIVE Aiming to achieve long-term disease control, maintenance systemic chemotherapy (MSC) with a 1-3-month drug-free interval is continued in selected patients. We report our experience of MSC for metastatic urothelial carcinoma (UC). METHODS Of 228 metastatic UC patients treated with systemic chemotherapy, 40 (17.5%, 40/228) had continuously undergone MSC. Data on the regimen, cycle number, and reason for the discontinuation of MSC were also collected. We analyzed OS from the initiation of MSC until death or the last follow-up, using the log-rank test to assess the significance of differences. RESULTS The median number of cycles of chemotherapy was 6, and the responses were CR in 6, PR in 20, SD in 13, and PD in 1 before MSC. Gemcitabine plus CDDP or carboplatin was mainly performed as MSC (70%, 28/40). MSC was repeated quarterly in 30 (75%, 30/40), every two months in 8 (20%, 8/40), and with other intervals in 2 (5%, 2/40). Overall, a median of 3.5 cycles (range: 1-29) of MSC was performed. The reason for the discontinuation of MSC was PD in 24 (60%, 24/40), favorable disease control in 9 (22.5%, 9/40), and myelosuppression in 3 (7.5%, 3/40), and for other reasons in 2 (5%, 2/40). MSC was ongoing in 2 (5%, 2/40). The median OS was 27 months from the initiation of MSC. PS0 (P = 0.0169), the absence of lung metastasis (P = 0.0387), and resection of the primary site (P = 0.0495) were associated with long-term survival after MSC. CONCLUSIONS In selected patients, long-term systemic chemotherapy could be performed with a drug-free interval. Our maintenance strategy with cytotoxic drugs may become one of the treatment options for long-term disease control.

Abstract
Identifying the two-dimensional (2D) topological insulating (TI) state in new materials and its control are crucial aspects towards the development of voltage-controlled spintronic devices with low-power dissipation. Members of the 2D transition metal dichalcogenides have been recently predicted and experimentally reported as a new class of 2D TI materials, but in most cases edge conduction seems fragile and limited to the monolayer phase fabricated on specified substrates. Here, we realize the controlled patterning of the 1T^{'} phase embedded into the 2H phase of thin semiconducting molybdenum-disulfide by laser beam irradiation. Integer fractions of the quantum of resistance, the dependence on laser-irradiation conditions, magnetic field, and temperature, as well as the bulk gap observation by scanning tunneling spectroscopy and theoretical calculations indicate the presence of the quantum spin Hall phase in our patterned 1T^{'} phases.

Abstract
A pulsed laser deposition system with rapid beam deflection (RBD-PLD) by a galvanometer mirror scanner has been developed for alternating ablation of multiple targets with a single laser instrument. In this system, the alternating deposition of different target materials is carried out by scanning the laser beam between the positionally fixed targets with a galvanometer mirror instead of mechanically switching the target positions on a fixed optical path of the laser beam as is done in conventional pulsed laser deposition (PLD) systems. Thus, the "wait" time required for switching target materials to be deposited, which typically takes several seconds in a conventional system, can be made as short as a few milliseconds. We demonstrate some of the advantages of this PLD system in several technologically important aspects of thin film synthesis: (1) fast fabrication of binary alloy films, (2) preparation of natural composition spread libraries, (3) effect of the target switching time on the deposition of volatile compounds, (4) control of the degree of mixing of two different materials in a film, and (5) efficient growth of compositionally graded thin films.

Abstract
Although prostate cancer control using radiotherapy is dose‐dependent, dose–volume effects on late toxicities in organs at risk, such as the rectum and bladder, have been observed. Both protons and carbon ions offer advantageous physical properties for radiotherapy, and create favorable dose distributions using fewer portals compared with photon‐based radiotherapy. Thus, particle beam therapy using protons and carbon ions theoretically seems suitable for dose escalation and reduced risk of toxicity. However, it is difficult to evaluate the superiority of particle beam radiotherapy over photon beam radiotherapy for prostate cancer, as no clinical trials have directly compared the outcomes between the two types of therapy due to the limited number of facilities using particle beam therapy. The Japanese Society for Radiation Oncology organized a joint effort among research groups to establish standardized treatment policies and indications for particle beam therapy according to disease, and multicenter prospective studies have been planned for several common cancers. Clinical trials of proton beam therapy for intermediate‐risk prostate cancer and carbon‐ion therapy for high‐risk prostate cancer have already begun. As particle beam therapy for prostate cancer is covered by the Japanese national health insurance system as of April 2018, and the number of facilities practicing particle beam therapy has increased recently, the number of prostate cancer patients treated with particle beam therapy in Japan is expected to increase drastically. Here, we review the results from studies of particle beam therapy for prostate cancer and discuss future developments in this field.

Abstract
364 Background: Bladder-preserving therapy with a real-time tumor-tracking radiotherapy system (RTRT system) has been used for muscle-invasive bladder cancer (MIBC) since 1998 in our institution. We evaluate long term outcomes of this therapy. Methods: From 1998 to 2016, 38 patients with a T2-T4N0M0 bladder cancer who were clinically inoperable or refused surgery were enrolled. Transurethral tumor resection (TUR) and 40 Gy irradiation to the whole bladder was followed by TUR of the tumor bed (1st Evaluation) and endoscopic implantation of fiducial markers in the bladder wall around the primary tumor. Then, a boost of 25 Gy was made to the primary tumor using RTRT system. Protocol TUR of the tumor bed was performed 6 months later (2nd Evaluation). Patients with adequate renal function (CCR>45ml/min) received concurrent chemoradiotherapy with nedaplatin (cisplatin analog made in Japan, 70mg/m2 intravenously, day1, day22, day50). Results: Median follow-up for surviving patients was 6 yr. 5- and 10-yr OS were 55%, 40%, and 5- and 10-yr PFS were 55% and 39%, respectively. The CR rate at 1st evaluation was 66%, in those patients 5- and 10-yr OS rates were 70% and 61%. Among the patients with non-CR at 1st evaluation, CR rate at 2nd evaluation was 31%. Local recurrence occurred in 13 patients. One of them was performed cystectomy and 9 were performed TUR and/or bladder injection therapy. 11 patients experienced distant recurrence, 2 of those was performed chemotherapy. In univariate analysis, male (OS; HR: 0.33, 95% CI: 0.12-0.92, PFS; HR:0.25, 95% CI: 0.09-0.69) and PS0-1 (OS; HR: 0.26, 95% CI: 0.09-0.79, PFS; HR: 0.29, 95% CI: 0.10-0.85) were significantly associated with good OS and PFS (shown in Table). In multivariate analysis, the both of these covariates were also significantly associated with good OS and PFS (male; OS; HR: 0.31, 95% CI: 0.11-0.88, PFS; HR: 0.21, 95% CI: 0.07-0.62, PS0-1; OS; HR: 0.25, 95% CI: 0.08-0.76, PFS; HR: 0.24, 95%CI: 0.09-0.75). Conclusions: Bladder-preserving therapy is a considerable option in patients medically unfit for or not desiring cystectomy.

Objective To assess the number of lymph nodes removed as a surrogate marker of the extent of lymph node dissection, and compare survival outcomes between laparoscopic radical nephroureterectomy (LRNU) and open radical nephroureterectomy (ORNU) in patients undergoing standardized lymph node dissection. Methods We retrospectively analyzed the data of 214 cTanyN0M0 patients undergoing radical NU with regional lymph node dissection according to the tumor location. The Kaplan–Meier method and Cox hazards model were utilized for survival analyses, including recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). Results A total of 114 patients underwent LRNU and 100 underwent ORNU. There was no significant difference in the pT stage, pN stage, or tumor grade, but distal ureteral tumors were more frequent in the LRNU group. The number of lymph nodes removed did not differ between the two groups [LRNU: 12 (median), ORNU: 11.5, P = 0.3852]. Lymph node metastasis was pathologically identified in 19 patients (8.9%). The 5-year RFS (ORNU: 71.7%, LRNU: 74%, P = 0.7829), CSS (77.8 and, 80%, P = 0.8441) and OS (72.8, and 75.9%, P = 0.3456) did not differ between the two groups. In the sub-analysis of pT3/4 patients (n = 83), there were no significant differences in RFS, CSS, or OS between the two groups, although Kaplan–Meier survival curves were slightly better for those receiving ORNU. In the multivariate model, LRNU was not significantly correlated with a poorer RFS, CSS or OS. Conclusion Our data support the feasibility of lymph node dissection with a laparoscopic approach and the equivalent oncological outcome of LRNU compared with ORNU when regional lymph node dissection is performed. However, LRNU should be performed after careful patient selection for advanced disease.

Outcome and prognostic factors in metastatic urothelial carcinoma patients receiving second-line chemotherapy: an analysis of real-world clinical practice data in Japan. Jpn J Clin Oncol 2018; 48:771-776.

Abstract
Objectives The objective of the present study was to investigate the survival outcome and prognostic factors of metastatic urothelial carcinoma patients treated with second-line systemic chemotherapy in real-world clinical practice. Methods Overall, 114 patients with metastatic urothelial carcinoma undergoing second-line systemic chemotherapy were included in this retrospective analysis. The dominant second-line chemotherapy was a paclitaxel-based combination regimen (60%, 68/114). We assessed the progression-free survival and overall survival times using the Kaplan–Meier method. The Cox proportional hazards model was applied to identify the factors affecting overall survival. Results The median progression-free survival and overall survival times were 4 and 9 months, respectively. In the multivariate analysis, an Eastern Cooperative Oncology Group performance status score greater than 0 at presentation, C-reactive protein level ≧1 mg/dl and poor response to prior chemotherapy were adverse prognostic indicators. Patients with 0, 1, 2 and 3 of those risk factors had a median overall survival of 17, 12, 7 and 3 months, respectively. Conclusions The Eastern Cooperative Oncology Group performance status at presentation, C-reactive protein level and response to prior chemotherapy were prognostic factors for metastatic urothelial carcinoma patients undergoing second-line chemotherapy. In the future, this information might help guide the choice of salvage treatment, such as second-line chemotherapy or immune checkpoint inhibitors, after the failure of first-line chemotherapy.

Measurement of Prompt D^{0} Meson Azimuthal Anisotropy in Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV. PHYSICAL REVIEW LETTERS 2018; 120:202301.

Abstract
The prompt D^{0} meson azimuthal anisotropy coefficients, v_{2} and v_{3}, are measured at midrapidity (|y|<1.0) in Pb-Pb collisions at a center-of-mass energy sqrt[s_{NN}]=5.02 TeV per nucleon pair with data collected by the CMS experiment. The measurement is performed in the transverse momentum (p_{T}) range of 1 to 40 GeV/c, for central and midcentral collisions. The v_{2} coefficient is found to be positive throughout the p_{T} range studied. The first measurement of the prompt D^{0} meson v_{3} coefficient is performed, and values up to 0.07 are observed for p_{T} around 4 GeV/c. Compared to measurements of charged particles, a similar p_{T} dependence, but smaller magnitude for p_{T}<6 GeV/c, is found for prompt D^{0} meson v_{2} and v_{3} coefficients. The results are consistent with the presence of collective motion of charm quarks at low p_{T} and a path length dependence of charm quark energy loss at high p_{T}, thereby providing new constraints on the theoretical description of the interactions between charm quarks and the quark-gluon plasma.

Abstract
A study of the associated production of a Z boson and a charm quark jet ( Z + c ), and a comparison to production with a b quark jet ( Z + b ), in p p collisions at a centre-of-mass energy of 8TeV are presented. The analysis uses a data sample corresponding to an integrated luminosity of 19.7fb - 1 , collected with the CMS detector at the CERN LHC. The Z boson candidates are identified through their decays into pairs of electrons or muons. Jets originating from heavy flavour quarks are identified using semileptonic decays of c or b flavoured hadrons and hadronic decays of charm hadrons. The measurements are performed in the kinematic region with two leptons withp T ℓ > 20 GeV ,| η ℓ | < 2.1 , 71 < m ℓ ℓ < 111 GeV , and heavy flavour jets withp T jet > 25 GeV and| η jet | < 2.5 . The Z + c production cross section is measured to be σ ( p p → Z + c + X ) B ( Z → ℓ + ℓ - ) = 8.8 ± 0.5 (stat) ± 0.6 (syst) pb . The ratio of the Z + c and Z + b production cross sections is measured to be σ ( p p → Z + c + X ) / σ ( p p → Z + b + X ) = 2.0 ± 0.2 (stat) ± 0.2 (syst) . The Z + c production cross section and the cross section ratio are also measured as a function of the transverse momentum of the Z boson and of the heavy flavour jet. The measurements are compared with theoretical predictions.

Abstract
The relative yields of ϒ mesons produced in pp and Pb-Pb collisions at sqrt[s_{NN}]=5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are formed by comparing the yields of the excited states, ϒ(2S) and ϒ(3S), to the ground state, ϒ(1S), in both Pb-Pb and pp collisions at the same center-of-mass energy. The double ratios, [ϒ(nS)/ϒ(1S)]_{Pb-Pb}/[ϒ(nS)/ϒ(1S)]_{pp}, are measured to be 0.308±0.055(stat)±0.019(syst) for the ϒ(2S) and less than 0.26 at 95% confidence level for the ϒ(3S). No significant ϒ(3S) signal is found in the Pb-Pb data. The double ratios are studied as a function of collision centrality, as well as ϒ transverse momentum and rapidity. No significant dependencies are observed.

Study of dijet events with a large rapidity gap between the two leading jets in pp collisions at s = 7 TeV. THE EUROPEAN PHYSICAL JOURNAL. C, PARTICLES AND FIELDS 2018; 78:242.

Abstract
Events with no charged particles produced between the two leading jets are studied in proton-proton collisions ats = 7 TeV . The jets were required to have transverse momentump T jet > 40 GeV and pseudorapidity1.5 < | η jet | < 4.7 , and to have values of η jet with opposite signs. The data used for this study were collected with the CMS detector during low-luminosity running at the LHC, and correspond to an integrated luminosity of 8pb - 1 . Events with no charged particles withp T > 0.2 GeV in the interval - 1 < η < 1 between the jets are observed in excess of calculations that assume no color-singlet exchange. The fraction of events with such a rapidity gap, amounting to 0.5-1% of the selected dijet sample, is measured as a function of the p T of the second-leading jet and of the rapidity separation between the jets. The data are compared to previous measurements at the Tevatron, and to perturbative quantum chromodynamics calculations based on the Balitsky-Fadin-Kuraev-Lipatov evolution equations, including different models of the non-perturbative gap survival probability.

Observation of Correlated Azimuthal Anisotropy Fourier Harmonics in pp and p+Pb Collisions at the LHC. PHYSICAL REVIEW LETTERS 2018; 120:092301.

Abstract
The azimuthal anisotropy Fourier coefficients (v_{n}) in 8.16 TeV p+Pb data are extracted via long-range two-particle correlations as a function of the event multiplicity and compared to corresponding results in pp and PbPb collisions. Using a four-particle cumulant technique, v_{n} correlations are measured for the first time in pp and p+Pb collisions. The v_{2} and v_{4} coefficients are found to be positively correlated in all collision systems. For high-multiplicity p+Pb collisions, an anticorrelation of v_{2} and v_{3} is observed, with a similar correlation strength as in PbPb data at the same multiplicity. The new correlation results strengthen the case for a common origin of the collectivity seen in p+Pb and PbPb collisions in the measured multiplicity range.

Measurements of the p p → Z Z production cross section and the Z → 4 ℓ branching fraction, and constraints on anomalous triple gauge couplings at s = 13 TeV. THE EUROPEAN PHYSICAL JOURNAL.

Abstract
Four-lepton production in proton-proton collisions, p p → ( Z / γ ∗ ) ( Z / γ ∗ ) → 4 ℓ , where ℓ = e or μ , is studied at a center-of-mass energy of 13TeV with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 35.9fb - 1 . The ZZ production cross section, σ ( p p → Z Z ) = 17.2 ± 0.5 (stat) ± 0.7 (syst) ± 0.4 (theo) ± 0.4 (lumi) pb , measured using events with two opposite-sign, same-flavor lepton pairs produced in the mass region 60 < m ℓ + ℓ - < 120 GeV , is consistent with standard model predictions. Differential cross sections are measured and are well described by the theoretical predictions. The Z boson branching fraction to four leptons is measured to be B ( Z → 4 ℓ ) = 4 . 83 - 0.22 + 0.23 ( s t a t ) - 0.29 + 0.32 ( s y s t ) ± 0.08 ( t h e o ) ± 0.12 ( l u m i ) × 10 - 6 for events with a four-lepton invariant mass in the range 80 < m 4 ℓ < 100 GeV and a dilepton massm ℓ ℓ > 4 GeV for all opposite-sign, same-flavor lepton pairs. The results agree with standard model predictions. The invariant mass distribution of the four-lepton system is used to set limits on anomalous ZZZ and ZZ γ couplings at 95% confidence level: - 0.0012 < f 4 Z < 0.0010 , - 0.0010 < f 5 Z < 0.0013 , - 0.0012 < f 4 γ < 0.0013 , - 0.0012 < f 5 γ < 0.0013 .

Abstract
Four-lepton production in proton-proton collisions, p p → ( Z / γ ∗ ) ( Z / γ ∗ ) → 4 ℓ , where ℓ = e or μ , is studied at a center-of-mass energy of 13 TeV with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 35.9 fb - 1 . The ZZ production cross section, σ ( p p → Z Z ) = 17.2 ± 0.5 (stat) ± 0.7 (syst) ± 0.4 (theo) ± 0.4 (lumi) pb , measured using events with two opposite-sign, same-flavor lepton pairs produced in the mass region 60 < m ℓ + ℓ - < 120 GeV , is consistent with standard model predictions. Differential cross sections are measured and are well described by the theoretical predictions. The Z boson branching fraction to four leptons is measured to be B ( Z → 4 ℓ ) = 4 . 83 - 0.22 + 0.23 ( s t a t ) - 0.29 + 0.32 ( s y s t ) ± 0.08 ( t h e o ) ± 0.12 ( l u m i ) × 10 - 6 for events with a four-lepton invariant mass in the range 80 < m 4 ℓ < 100 GeV and a dilepton mass m ℓ ℓ > 4 GeV for all opposite-sign, same-flavor lepton pairs. The results agree with standard model predictions. The invariant mass distribution of the four-lepton system is used to set limits on anomalous ZZZ and ZZ γ couplings at 95% confidence level: - 0.0012 < f 4 Z < 0.0010 , - 0.0010 < f 5 Z < 0.0013 , - 0.0012 < f 4 γ < 0.0013 , - 0.0012 < f 5 γ < 0.0013 .

A longitudinal assessment of health-related quality of life in patients undergoing active surveillance for early prostate cancer in Japan (PRIAS-JAPAN). J Clin Oncol 2018. [DOI: 10.1200/jco.2018.36.6_suppl.56] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
56 Background: There are few reports of the health-related quality of life (HRQOL) of Asian prostate cancer patients who choice active surveillance. We evaluate HRQOL in participants of the Prostate Cancer Research International Active Surveillance study (PRIAS-JAPAN). Methods: The participants’ general HRQOL was assessed longitudinally using the Short Form 8 Health Survey (SF-8) at enrollment and annually thereafter until discontinuation of active surveillance (AS). We compared the quality of life and baseline score of participants with that of the general population (Norm-based scoring [NBS] 50) using paired t-test and the mixed models. Age-adjusted logistic regression was applied to the 3-year AS remaining rate. Results: The SF-8 questionnaire was administered to 570 patients (median age, 68 [range, 45–87] years). We evaluated 484, 328, 140, 84, and 68 patients at enrollment and 1, 2, 3, and 4 years thereafter. At enrollment, the mean physical component summary (PCS) score and all subscales revealed better HRQOL than NBS. No significant difference was noted in mental component summary (MCS) compared to NBS at enrollment. However, MCS at 1, 2, and 4 years was higher than the NBS. PCS slightly diminished in 4 years, whereas MCS at all time points showed no change. Age-adjusted logistic regression showed an OR of 1.66 (95% CI: 1.047–2.632, P = 0.0313) on 3-year AS remaining rate in favor of patients with above median MCS at enrollment. Conclusions: Men who were enrolled into the PRIAS-JAPAN study had better HRQOL than that of NBS. PCS decreased but MCS did not. The AS remaining rate was influenced by baseline MCS.
