Abstract
ABSTRACT A 64-year-old woman presented with chest pain while eating and was referred to our hospital. Physical examination revealed abdominal distension, tenderness, and lower-extremity edema. Imaging revealed a large gallbladder tumor infiltrating the liver, with ascites and pleural effusion. A biopsy confirmed a poorly differentiated adenocarcinoma with SMARCA4 deficiency (cT3N2M1, cStage IV). Chemotherapy was ineffective and led to tumor progression. The patient died 9 months later. Recently, attention has been paid to SMARCA4 deficiency, which is a genetic mutation found in tumors. Here, we report on poorly differentiated adenocarcinomas of the gallbladder based on imaging findings, including FDG PET.

Abstract
Neuroendocrine carcinoma (NEC) of the gallbladder origin is particularly rare, accounting for only 0.38% of primary malignancies of the gallbladder, and standard therapies are limited. The MET gene encodes the tyrosine kinase receptor, c-Met. Pathogenic variants of MET, such as MET exon 14 skipping and MET amplification, result in excessive downstream signaling that promotes tumor progression. A MET inhibitor, capmatinib, blocks signaling of c-Met and has been approved by the Food and Drug Administration for non-small cell lung cancer with MET exon 14 skipping. The effectiveness of capmatinib has been reported in other cancers with MET amplification, but NEC with MET variants has not been reported. Here, we present a case of a 72-year-old woman with NEC of the gallbladder with multiple liver and lymph node metastases, who was resistant to conventional chemotherapy including carboplatin plus etoposide as first-line treatment and irinotecan as second-line treatment, but she responded to capmatinib. After 6 weeks of treatment, CT scan showed a partial response (80% reduction in size), but after 13 weeks, regrowth of liver metastasis was observed. Herein, we report a meaningful efficacy of capmatinib to the patient of NEC of the gallbladder origin with MET amplification.

Abstract
Despite advanced therapeutics, esophageal squamous cell carcinoma (ESCC) remains one of the deadliest cancers. Here, we propose a novel therapeutic strategy based on synthetic lethality combining trifluridine/tipiracil and MK1775 (WEE1 inhibitor) as a treatment for ESCC. This study demonstrates that trifluridine induces single-strand DNA damage in ESCC cells, as evidenced by phosphorylated replication protein 32. The DNA damage response includes cyclin-dependent kinase 1 (CDK1) (Tyr15) phosphorylation as CDK1 inhibition and a decrease of the proportion of phospho-histone H3 (p-hH3)-positive cells, indicating cell cycle arrest at the G2 phase before mitosis entry. The WEE1 inhibitor remarkedly suppressed CDK1 phosphorylation (Try15) and reactivated CDK1, and also increased the proportion of p-hH3-positive cells, which indicates an increase of the number of cells into mitosis. Trifluridine combined with a WEE1 inhibitor increased trifluridine-mediated DNA damage, namely DNA double-strand breaks, as shown by increased γ-H2AX expression. Moreover, the combination treatment with trifluridine/tipiracil and a WEE1 inhibitor significantly suppressed tumor growth of ESCC-derived xenograft models. Hence, our novel combination treatment with trifluridine/tipiracil and a WEE1 inhibitor is considered a candidate treatment strategy for ESCC.

Abstract
IMPORTANCE Precision oncology using comprehensive genomic profiling (CGP) by next-generation sequencing is aimed at companion diagnosis and genomic profiling. The clinical utility of CGP before the standard of care (SOC) is still not resolved, and more evidence is needed. OBJECTIVE To investigate the clinical utility of next-generation CGP (FoundationOne CDx [F1CDx]) in patients with previously untreated metastatic or recurrent solid tumors. DESIGN, Setting, and Participants This multicenter, prospective, observational cohort study enrolled patients with previously untreated advanced solid tumors between May 18, 2021, and February 16, 2022, with follow-up through August 16, 2022. The study was conducted at 6 hospitals in Japan. Eligible patients were aged 20 years or older and had Eastern Cooperative Oncology Group performance status of 0 to 1 with previously untreated metastatic or recurrent cancers in the gastrointestinal or biliary tract; pancreas, lung, breast, uterus, or ovary; and malignant melanoma. EXPOSURE Comprehensive genomic profiling testing before SOC for advanced solid tumors. MAIN OUTCOMES AND MEASURES Proportion of patients with actionable or druggable genomic alterations and molecular-based recommended therapy (MBRT). RESULTS A total of 183 patients met the inclusion criteria and 180 patients (92 men [51.1%]) with a median age of 64 years (range, 23-88 years) subsequently underwent CGP (lung [n = 28], colon/small intestine [n = 27], pancreas [n = 27], breast [n = 25], biliary tract [n = 20], gastric [n = 19], uterus [n = 12], esophagus [n = 10], ovary [n = 6], and skin melanoma [n = 6]). Data from 172 patients were available for end point analyses. Actionable alterations were found in 172 patients (100.0%; 95% CI, 97.9%-100.0%) and druggable alternations were identified in 109 patients (63.4%; 95% CI, 55.7%-70.6%). The molecular tumor board identified MBRT for 105 patients (61.0%; 95% CI, 53.3%-68.4%). Genomic alterations included in the companion diagnostics list of the CGP test were found in 49 patients (28.5%; 95% CI, 21.9%-35.9%) in a tumor-agnostic setting. After a median follow-up of 7.9 months (range, 0.5-13.2 months), 34 patients (19.8%; 95% CI, 14.1%-26.5%) received MBRT. CONCLUSIONS AND RELEVANCE The findings of this study suggest that CGP testing before SOC for patients with advanced solid tumors may be clinically beneficial to guide the subsequent anticancer therapies, including molecularly matched treatments.

Abstract
Next-generation sequencing (NGS)-based gene profiling can identify patients with pancreatic cancer with homologous recombinant repair gene pathogenic variants (HRRv). Several retrospective studies have reported a positive association between HRRv and the efficacy of platinum-based chemotherapy. However, this association remains to be validated in a prospective study. This multicenter, prospective, observational study included patients with histologically confirmed unresectable or recurrent pancreatic cancer who required systemic chemotherapy. Patients who were oxaliplatin-naïve patients were eligible. The HRRv status was measured using a College of American Pathologists-accredited NGS panel. One-year overall survival rate (1yr-OS%) was calculated after initiation of oxaliplatin-based chemotherapy and was set as the primary endpoint. Forty patients were enrolled between August 2018 and March 2020. The NGS success rate was 95% (38/40). HRRv was detected in 11 patients (27.5%). Oxaliplatin-based chemotherapy was administered to 9 of 11 patients with HRRv (81.8%) and 15 of 29 patients with non-HRRv (51.7%). The 1yr-OS% after initiation of oxaliplatin-based chemotherapy was 44.4% [95% confidence interval (CI) 13.7-71.9] and 57.1% (95% CI 28.4-78.0) in HRRv-positive and -negative cohorts, respectively. These data suggested that HRRv status alone could not be a potential predictive marker of oxaliplatin-based chemotherapy in patients with advanced pancreatic cancer. These results were in line with the results of a recent phase II study reporting the limited efficacy of poly(adenosine diphosphate-ribose) polymerase inhibitor in patients with pancreatic cancer who harbored HRRv other than BRCA. Future studies investigating patients with biallelic HRRv in the first-line setting are warranted.Trial registration UMIN000033655.

Abstract
Background Aberrant fibroblast growth factor receptor (FGFR) signaling can substantially influence oncogenicity. Despite that FGFR gene abnormality is often detected by cancer genome profiling tests, there is no tumor-agnostic approval yet for these aberrations. E7090 (tasurgratinib) is an orally available selective tyrosine kinase inhibitor of FGFR1-3. Specific FGFR alterations were previously reported to be highly sensitive to E7090 based on a high-throughput functional evaluation method, called mixed-all-nominated-mutants-in-one (MANO) method, narrowing down the most promising targets. This trial was focused on the alterations identified by the MANO method and was performed under the nationwide large registry network for rare cancers in Japan (MASTER KEY Project). Methods/Design This single-arm Phase 2 trial was designed to evaluate the safety and efficacy of E7090 in patients with advanced or recurrent solid tumors harboring FGFR alterations. Three cohorts were set based on the type of FGFR alterations and the results of MANO method. A maximum of 45 patients will be enrolled from 5 institutions over 2.5 years. E7090 will be administered once daily as an oral single agent in 28-day cycles. The primary endpoint is the objective overall response rate; whereas, the secondary endpoints include progression-free survival, overall survival, disease control rate, safety, duration of response, and time to response. Ethics approval was granted by the National Cancer Center Hospital Certified Review Board. Patient enrollment began in June 2021. Discussion A unique investigator-initiated multicenter Phase 2 trial was designed based on the results of preclinical investigation aiming to acquire the approval of E7090 for solid tumors harboring FGFR gene alterations. The findings may serve as a novel model for the development of tumor-agnostic molecular targeted therapies against rare genetic abnormalities.

Abstract
BACKGROUND The European Society for Medical Oncology Precision Medicine Working Group (ESMO-PMWG) published recommendations regarding confirmatory germline testing for presumed germline pathogenic variants (PGPVs) in tumor-only comprehensive genomic profiling (CGP). However, the clinical validity of these recommendations has not been investigated in a real-world practice. METHODS Medical records of 180 consecutive patients who obtained the results of a tumor-only CGP (FoundationOne® CDx, Foundation Medicine, Inc, Cambridge, MA, USA) between October 2018 and March 2020, were retrospectively reviewed. After excluding patients with no reported variants in 45 actionable genes (n = 6), or no archived germline DNA samples (n = 31), 143 patients were investigated. The PGPVs were selected from the CGP report and germline sequencing were performed using DNA samples archived in Clinical Bioresource Center in Kyoto University Hospital (Kyoto, Japan). RESULTS A total of 195 variants were classified as PGPV based on the conventional criteria. Germline sequencing disclosed that 12 variants (6.2%) were of germline origin. In contrast, after filtering these 195 variants through the ESMO-PMWG recommendation criteria for confirmatory germline testing, following seven PGPVs, BRCA2 (n = 2), BRIP1 (n = 1), BAP1 (n = 1), PMS2 (n = 1), MSH2 (n = 1), and SDHB (n = 1) remained and six variants (85.7%) were confirmed to be of germline origin. CONCLUSION Our current data suggested that the application of ESMO-PMWG criteria is helpful in selecting PGPVs with a high likelihood of germline origin in a tumor-only CGP in daily clinical practice.

Abstract
BACKGROUND Tumor heterogeneity has been known to cause inter-assay discordance among next-generation sequencing (NGS) results. However, whether preclinical factors such as sample type, sample quality and analytical features of gene panel can affect the concordance between two different assays remains largely unexplored. METHODS Replicate sets of DNA samples extracted from formalin-fixed paraffin-embedded tissues (FFPE) (n = 20) and fresh frozen (FF) tissues (n = 10) were herein analyzed using a tumor-only (TO) and paired tumor-normal (TN) gene panel in laboratories certified by the Clinical Laboratory Improvement Amendment. Reported variants from the TO and TN panels were then compared. Furthermore, additional FFPE samples were sequentially sliced from the same FFPE block and submitted to another TN panel assay. RESULTS Substantial discordance (71.8%) was observed between the results of the two panels despite using identical DNA samples, with the discordance rate being significantly higher for FFPE samples (p < 0.05). Among the 99 variants reported only in the TO panel, 32.3% were consistent with germline variants, which were excluded in the TN panel, while 30.3% had an allele frequency of less than 5%, some of which were highly likely to be artificial calls. The comparison of two independent TN panel assay results from the same FFPE block also showed substantial discordance rate (55.3%). CONCLUSIONS In the context of clinical settings, our comparative analysis revealed that inter-NGS assay discordance commonly occurred due to sample types and the different analytical features of each panel.

Abstract
555 Background: The latest National Comprehensive Cancer Network Guidelines for pancreatic adenocarcinoma recommended platinum-based chemotherapy for the patients with germline BRCA1/2 or PALB2 variants based on retrospective studies. However, the association between the efficacy of oxaliplatin-based chemotherapy and homologous recombination repair (HRR)-related gene variants has not yet been evaluated in a prospective study. Methods: This was a multicenter, prospective, observational study. Key inclusion criteria were: histologically confirmed pancreatic adenocarcinoma or adenosquamous carcinoma; candidates for systemic chemotherapy or currently under systemic chemotherapy for unresectable disease; age ≥ 20 years; Eastern Cooperative Oncology Group Performance Status 0–2; formalin-fixed paraffin-embedded cancer tissue available for genomic sequencing; and adequate hematological, liver, and renal function. Patients were assessed with the next generation sequencing (NGS)-based ACT-repair panel (ACT genomics; Taipei, Taiwan). ACT-repair panel is accredited by College of American Pathologists and is designed to detect short variants (SVs) including substitutions, insertions, deletions, and copy number variants of 35 genes including 8 HRR-related genes ( ATM, ATR, BRCA1, BRCA2, PALB2, RAD51B, RAD51C, RAD51D). The primary endpoint was the one-year overall survival rate (1yr-OS%) after the initiation of oxaliplatin-based chemotherapy in patients who harbored pathogenic HRR gene variants. On the basis of published retrospective data, expected 1yr-OS% was set at ≥ 60% in this study. Results: Forty patients were enrolled from August 2018 to March 2020. Median age was 67 years (range, 49–81 years). Sequencing data were obtained from 39 patients (NGS success rate = 97.5%). Nine patients (22.5%) harboring HRR gene; ATM SVs (n = 4), BRCA2 loss of heterozygosity (LOH) (n = 3), BRCA2 SVs (n = 1), and PALB2 LOH (n = 1). Three patients received oxaliplatin-based chemotherapy as first-line chemotherapy, while the remaining six patients received it as second- or later-line oxaliplatin-based chemotherapy. The 1yr-OS% was 44.4%, and the median overall survival was 221 days (95% confidence interval, 79–NA days) after the initiation of oxaliplatin-based chemotherapy. In three patients who received oxaliplatin-based chemotherapy as first-line treatment, overall survivals were 703 (alive), 694 (alive), and 405 (dead) days, respectively. Conclusions: Efficacy of oxaliplatin-based chemotherapy on advanced pancreatic cancer harboring HRR-related gene variants did not meet the primary endpoint of 1yr-OS% (≥ 60%). Clinical trial information: UMIN000033655.

Abstract
Background: Genetic alterations of FGFRs are known to play an important role in the proliferation, survival, and migration of cancer cells as well as tumor angiogenesis and drug resistance. E7090 is an orally available selective tyrosine kinase inhibitor for FGFR1-3. A global Phase 2 study of E7090 in subjects with unresectable advanced or metastatic cholangiocarcinoma harboring FGFR2 gene fusion is ongoing (NCT04238715). We recently reported FGFR alterations that are highly sensitive to E7090 using a high-throughput functional evaluation method called MANO method (Nakamura et al. npj Precision Oncology, 2021), narrowing down the most promising FGFR alteration targets. Here, we designed a single-arm, open-label, investigator-initiated multicenter Phase 2 basket study to evaluate the efficacy and safety of E7090 in subjects with advanced or recurrent solid tumors harboring FGFR gene alterations, focusing on alterations identified by MANO method, as a sub-study under the nationwide large registry for rare cancers in Japan (MASTER KEY Project). Methods: The key eligibility criteria are: 1) Histologically confirmed metastatic or locally advanced solid tumor; 2) Ineffective to or intolerant to first line treatment, or for which standard treatment is no longer available; and 3) Confirmed FGFR gene alterations via next-generation sequencing assays that are reimbursed by insurance. Subjects will receive E7090 140 mg orally once daily until disease progression or development of unacceptable toxicity. The primary endpoint is objective response rate (ORR) by independent central review (RECIST v1.1), and the secondary endpoints include ORR by investigator assessment, progression-free survival, overall survival, disease control rate, safety, duration of response, and time to response. For primary brain tumors, RANO criteria is also applied in assessment of response. The study enrolls approximately 45 subjects.

Abstract
OBJECTIVE The purpose of this study was to evaluate the effects of high tibial osteotomy (HTO) on the biological status of knee osteoarthritis (OA) using joint markers in synovial fluid (SF). METHODS Fifty patients with medial compartmental OA of the knee who underwent opening wedge HTO were enrolled. Paired SF samples from the affected knee and arthroscopic evaluation of articular cartilage were collected at the time of HTO surgery and the time of plate removal (postoperative 17 ± 4 months). The concentrations of the following SF biomarkers were measured: interleukin (IL)-1β, IL-6, IL-8, IL-10, tumour necrosis factor-α, matrix metalloproteinase (MMP)-2, MMP-3, MMP-9, MMP-13, vascular endothelial growth factor (VEGF), and cartilage oligomeric matrix protein (COMP). The Knee Society Score (KSS) and hip-knee-ankle (HKA) angle were assessed before and 2 years after HTO. RESULTS The KSS knee and function scores were significantly improved after HTO (mean changes of 36.4 and 23.7, respectively). The mean HKA angle was altered from mechanical varus (-8.6°) to valgus (5.2°). Concentrations of IL-6, IL-8, MMP-2, MMP-3, MMP-13, VEGF, and COMP in SF were significantly decreased after HTO (mean changes of -49.1%, -30.2%, -31.1%, -26.3%, -30.8%, -42.5%, and -13.7% from preoperative baseline, respectively). The cartilage status was improved in 19 cases (38%) after HTO. However, changes of all biomarkers were not significantly different between subjects with and without an improved cartilage status. CONCLUSIONS SF levels of biochemical markers for cartilage degradation and synovial inflammation were altered after HTO, suggesting an improvement in the OA disease state.

Abstract
e22524 Background: Presumed germline pathogenic variants (PGPVs) can be detected in tumor tissues using comprehensive genomic profiling. Clinicians and patients can decide whether to conduct confirmatory germline testing or not. However, the promoting and obstructive factors for confirmatory germline testing are unclear. Methods: This single institutional retrospective study aimed to identify factors related to confirmatory germline testing in patients with PGPVs. Between April 2015 and April 2019, 270 consecutive patients with cancers of unknown primary site, rare tumors, or solid tumors refractory to standard chemotherapy, who underwent tumor-only comprehensive genomic profiling were reviewed. PGPVs were proposed to be disclosed as variants to the patients by our institutional molecular tumor board. Univariate logistic regression analysis was conducted to investigate the relationship between each patient’s characteristics and confirmatory germline testing. Factors showing a statistical relationship (p < 0.10 in univariate analyses) were included in multivariate logistic regression analysis with a backward selection of variables. Statistical significance was set at p < 0.05. Results: Of the 270 patients who underwent tumor-only comprehensive genomic profiling, 77 possessed PGPVs. The most common PGPVs were TP53 (n = 56), APC (n = 9), PTEN (n = 7), RB1 (n = 6), and BRCA2 (n = 6). Among the 77 patients, only 11 (14.3%) chose to undergo confirmatory germline testing. Multivariate logistic regression analysis revealed that the person disclosing the results (experienced oncologists with knowledge of cancer genome medicine vs. others, odds ratio [OR]: 27.7, 95% confidence interval [CI]: 4.60–167) and study period (OR: 0.110, 95% CI: 0.015–0.787) were independently and significantly associated with confirmatory germline testing. Conclusions: These findings indicate that fostering genomic competency in oncologists and collaborating with genetic experts would facilitate cancer patients and their families to receive genetic medical services in the process of cancer genomic profiling.

Abstract
BACKGROUND Cancer of unknown primary (CUP) is usually treated with nonselective and empirical chemotherapy; however, its prognosis is generally poor, with a median survival of less than a year. Thus, clinicians eagerly await the development of more effective treatment strategies. In recent years, advances in next-generation sequencing (NGS) have made it possible to analyze comprehensively the genome of individual cancers. NGS has identified many genomic alterations, some of which are potential molecular targets of specific agents. We report a case of CUP that was successfully treated with targeted therapy directed by the genomic data obtained from an NGS-based multiplex assay. CASE PRESENTATION A 52-year-old Asian woman with right hip joint pain underwent fluorodeoxyglucose-positron emission tomography/computed tomography, which showed multiple metastatic tumors in her right hip joint, thyroid gland, lung, and vertebrae. Brain magnetic resonance imaging showed multiple cerebral metastases. Additional tests, including pathology examination and conventional epidermal growth factor receptor (EGFR) gene mutation analysis (single-strand conformation polymorphism assay), could not identify the primary origin of the tumors, so the patient was diagnosed with CUP. After empirical chemotherapy for CUP, an NGS-based multiplex assay performed using a resected specimen of thyroid tumor detected the EGFR mutation c.2573 T > G p.Leu858Arg (L858R). Her treatment was changed to erlotinib, an EGFR tyrosine-kinase inhibiter, which dramatically shrank the tumors and decreased her serum carcinoembryonic antigen level. She achieved long-term disease control and survived for 2 years and 9 months from the first diagnosis. CONCLUSION This case might support the strategy that NGS-based multiplex assays could identify actionable molecular targets for individual patients with CUP.

Abstract
Comprehensive genomic profiling (CGP) testing by next‐generation sequencing has been introduced into clinical practice as part of precision cancer medicine to select effective targeted therapies. However, whether CGP testing at the time of first‐line chemotherapy could be clinically useful is not clear. We conducted this single‐center, prospective, observational study to investigate the feasibility of CGP testing for chemotherapy‐naïve patients with stage III/IV gastrointestinal cancer, rare cancer, and cancer of unknown primary, using the FoundationOne® companion diagnostic (F1CDx) assay. The primary outcome was the detection rate of at least one actionable/druggable cancer genomic alteration. Actionable/druggable cancer genomic alterations were determined by the F1CDx report. An institutional molecular tumor board determined the molecular‐based recommended therapies. A total of 197 patients were enrolled from October 2018 to June 2019. CGP success rate was 76.6% (151 of 197 patients), and median turnaround time was 19 days (range: 10‐329 days). Actionable and druggable cancer genomic alterations were reported in 145 (73.6%) and 124 (62.9%) patients, respectively. The highest detection rate of druggable genomic alterations in gastrointestinal cancers was 80% in colorectal cancer (48 of 60 patients). Molecular‐based recommended therapies were determined in 46 patients (23.4%). CGP testing would be a useful tool for the identification of a potentially effective first‐line chemotherapy.

Abstract
Alcohol consumption is the key risk factor for the development of esophageal squamous cell carcinoma (ESCC), and acetaldehyde, a metabolite of alcohol, is an alcohol-derived major carcinogen that causes DNA damage. Aldehyde dehydrogenase2 (ALDH2) is an enzyme that detoxifies acetaldehyde, and its activity is reduced by ALDH2 gene polymorphism. Reduction in ALDH2 activity increases blood, salivary and breath acetaldehyde levels after alcohol intake, and it is deeply associated with the development of ESCC. Heavy alcohol consumption in individuals with ALDH2 gene polymorphism significantly elevates the risk of ESCC; however, effective prevention has not been established yet. In this study, we investigated the protective effects of Alda-1, a small molecule ALDH2 activator, on alcohol-mediated esophageal DNA damage. Here, we generated novel genetically engineered knock-in mice that express the human ALDH2*1 (wild-type allele) or ALDH2*2 gene (mutant allele). Those mice were crossed, and human ALDH2*1/*1, ALDH2*1/*2 and ALDH2*2/*2 knock-in mice were established. They were given 10% ethanol for 7 days in the presence or absence of Alda-1, and we measured the levels of esophageal DNA damage, represented by DNA adduct (N2-ethylidene-2′-deoxyguanosine). Alda-1 significantly increased hepatic ALDH2 activity both in human ALDH2*1/*2 and/or ALDH2*2/*2 knock-in mice and reduced esophageal DNA damage levels after alcohol drinking. Conversely, cyanamide, an ALDH2-inhibitor, significantly exacerbated esophageal DNA adduct level in C57BL/6N mice induced by alcohol drinking. These results indicate the protective effects of ALDH2 activation by Alda-1 on esophageal DNA damage levels in individuals with ALDH2 gene polymorphism, providing a new insight into acetaldehyde-mediated esophageal carcinogenesis and prevention.

Abstract
From June 2019, 2 different comprehensive genomic profiling(CGP)test panels were covered by National Health Insurance System in Japan. However, the indication of CGP was solid cancer patients refractory to standard chemotherapy or those without standard of care, while other countries indicate CGP to chemotherapy naIve advanced cancer patients. To be covered by National Health Insurance System, certified core hospital for genomic medicine should hold expert panel with affiliated hospitals. We develop a unique system for expert panel collaborated with SYSMEX Corporation to streamline medical staffs' effort. To provide precision medicine to cancer patients, we have to maximize the merit of CGP and solve several issues.

Abstract
Radiotherapy (RT) is the primary treatment for cancer. Ionizing radiation from RT induces tumor damage at the irradiated site, and, although clinically infrequent, may cause regression of tumors distant from the irradiated site-a phenomenon known as the abscopal effect. Recently, the abscopal effect has been related to prolongation of overall survival time in cancer patients, though the factors that influence the abscopal effect are not well understood. The aim of this study is to clarify the factors influencing on abscopal effect. Here, we established a mouse model in which we induced the abscopal effect. We injected MC38 (mouse colon adenocarcinoma) cells subcutaneously into C57BL/6 mice at two sites. Only one tumor was irradiated and the sizes of both tumors were measured over time. The non-irradiated-site tumor showed regression, demonstrating the abscopal effect. This effect was enhanced by an increase in the irradiated-tumor volume and by administration of anti-PD1 antibody. When the abscopal effect was induced by a combination of RT and anti-PD1 antibody, it was also influenced by radiation dose and irradiated-tumor volume. These phenomena were also verified in other cell line, B16F10 cells (mouse melanoma cells). These findings provide further evidence of the mechanism for, and factors that influence, the abscopal effect in RT.

Abstract
832 Background: From June, 2019, two comprehensive genomic profiling (CGP) assays, "FoundationOne CDx" and “OncoGuide NCC Oncopanel”, were reimbursed by the national insurance system in Japan for patients who were refractory to standard chemotherapy. However, their clinical utility for chemotherapy-naïve cancer patients is unknown. Methods: We conducted a single institutional prospective observational study to evaluate the clinical utility of FoundationOne CDx assay (Cambridge, MA, USA) for the patients with chemotherapy-naïve advanced gastrointestinal malignancies. Patients with adequate H.E. sample were registered in this study. Primary outcome was the detection rate of at least one actionable/druggable cancer genomic alterations. The evidence levels were classified according to clinical practice guidance for next-generation sequencing in cancer diagnosis and treatment (Edition 1.0) (Sunami K. Cancer Sci. 2018). Results: From October 2018 to June 2019, a total of 238 patients were screened and the following 158 patients were registered: colorectal cancer (n = 60), gastric cancer (n = 19), esophageal cancer (n = 23), pancreatic cancer (n = 30), biliary tract cancer (n = 11), rare gastrointestinal malignancies (n = 15). The CGP data were obtained for 113 patients . Median turn-around time was 14 days (range 10-247 days). Actionable/druggable cancer genomic alterations were observed in 113 patients (100%)/ 65 patients (57.5%), respectively. Clinically relevant biomarkers and genomic alterations were identified in 22 patients (19.5%); BRCA2 (n = 4), ERBB2 (n = 4) , BRAF (n = 3) , EGFR (n = 3), FGFR2 (n = 2), MET (n = 2), NTRK (n = 2) , MSI-H (n = 2 ), TMB-high (n = 2), ALK (n = 1) , KIT (n = 1) and ROS1 (n = 1). Of note, novel biomarkers such as ROS1- GOPC fusion and PALB2 rearrangement were obtained in the patients with esophageal squamous cell carcinoma. Conclusions: This is the first study to evaluate the clinical utility of CGP in patient with chemotherapy-naïve advanced gastrointestinal malignancies. Our result indicated that CGP might provide a chance of potentially effective drugs as a novel approach in precision cancer medicine. Clinical trial information: UMIN000034830.

Abstract
BACKGROUND Tumor mutational burden (TMB) measured via next-generation sequencing (NGS)-based gene panel is a promising biomarker for response to immune checkpoint inhibitors (ICIs) in solid tumors. However, little is known about the preanalytical factors that can affect the TMB score. MATERIALS AND METHODS Data of 199 patients with solid tumors who underwent multiplex NGS gene panel (OncoPrime), which was commercially provided by a Clinical Laboratory Improvement Amendments-licensed laboratory and covered 0.78 megabase (Mb) of capture size relevant to the TMB calculation, were reviewed. Associations between the TMB score and preanalytical factors, including sample DNA quality, sample type, sampling site, and storage period, were analyzed. Clinical outcomes of patients with a high TMB score (≥10 mutations per megabase) who received anti-programmed cell death protein 1 antibodies (n = 22) were also analyzed. RESULTS Low DNA library concentration (<5 nM), formalin-fixed paraffin-embedded tissue (FFPE), and the prolonged sample storage period (range, 0.9-58.1 months) correlated with a higher TMB score. After excluding low DNA library samples from the analysis, FFPE samples, but not the sample storage period, exhibited a marked correlation with a high TMB score. Of 22 patients with a high TMB score, we observed the partial response in 2 patients (9.1%). CONCLUSION Our results indicate that the TMB score estimated via NGS-based gene panel could be affected by the DNA library concentration and sample type. These factors could potentially increase the false-positive and/or artifactual variant calls. As each gene panel has its own pipeline for variant calling, it is unknown whether these factors have a significant effect in other platforms. IMPLICATIONS FOR PRACTICE A high tumor mutational burden score, as estimated via next-generation sequencing-based gene panel testing, should be carefully interpreted as it could be affected by the DNA library concentration and sample type.

Clinical outcomes of patients with a high TMB score (≥10 mutations/megabase) who received anti-PD-1 antibodies (n = 22) were also analyzed. Results: TMB score was significantly higher in samples that yielded a DNA library concentration of < 5 nM and in samples obtained from formalin-fixed paraffin-embedded tissue (FFPE) compared to fresh frozen tissue. The sample storage period was also positively correlated with TMB score. Of the 22 patients with a high TMB score, partial response and stable disease were observed in two (9.1%) and five (22.7%) cases, respectively. Among 15 non-responders, 11 (73.3%) had a low DNA library concentration, thereby indicating that a high TMB score might be attributable to false positive mutation calls. Conclusions: Our results suggest that the TMB score estimated via NGS-based gene panel assay could be affected by the DNA library concentration, sample type and storage period.

Abstract
BACKGROUND Esophageal squamous cell carcinoma (ESCC) is one of the most intractable cancers, so the development of novel therapeutics has been required to improve patient outcomes. Curcumin, a polyphenol from Curcuma longa, exhibits various health benefits including antitumor effects, but its clinical utility is limited because of low bioavailability. Theracurmin® (THC) is a highly bioavailable curcumin dispersed with colloidal submicron particles. METHODS We examined antitumor effects of THC on ESCC cells by cell viability assay, colony and spheroid formation assay, and xenograft models. To reveal its mechanisms, we investigated the levels of reactive oxygen species (ROS) and performed microarray gene expression analysis. According to those analyses, we focused on NQO1, which involved in the removal of ROS, and examined the effects of NQO1-knockdown or overexpression on THC treatment. Moreover, the therapeutic effect of THC and NQO1 inhibitor on ESCC patient-derived xenografts (PDX) was investigated. RESULTS THC caused cytotoxicity in ESCC cells, and suppressed the growth of xenografted tumors more efficiently than curcumin. THC increased ROS levels and activated the NRF2-NMRAL2P-NQO1 expressions. Inhibition of NQO1 in ESCC cells by shRNA or NQO1 inhibitor resulted in an increased sensitivity of cells to THC, whereas overexpression of NQO1 antagonized it. Notably, NQO1 inhibitor significantly enhanced the antitumor effects of THC in ESCC PDX tumors. CONCLUSIONS These findings suggest the potential usefulness of THC and its combination with NQO1 inhibitor as a therapeutic option for ESCC.

Abstract
Abstract
Most cancer patients experience disease progression despite one or multiple lines of treatment with cytotoxic chemotherapy. Evidence from human trials and in vivo experiments on patient-derived xenograft (PDX) tumor lines indicates that cancer stem cells (CSCs) can survive chemotherapy treatment. However, the mechanism of chemotherapy resistance in CSCs is not fully elucidated. To identify new mechanisms of the drug-resistance in colorectal cancer, we used gene-expression microarrays to examine the gene expression profile of CSCs and non-CSCs in four human PDX models of colorectal cancer, both before-and-after treatment with cytotoxic chemotherapy. The gene-expression data were analyzed using Independent Component Analysis (ICA) followed by Transcription Factor Target Genes (TFTG) enrichment analysis, which identified the transcription factor E2F4 as a candidate regulator of chemotherapy resistance in colorectal CSCs. E2F4 was predominantly expressed in the CSC-enriched cell population (CD44+/CD166+ human colorectal cancer cells). E2F4 knock-down sensitizes cancer cells to chemotherapy in three different PDX tumors as well as HT29 cells. Co-immunoprecipitation experiments showed that E2F4 forms a complex with p107 and DP-1, which also contributed to the chemotherapy resistance. Simultaneous knock-down of both E2F4 and p107 enhanced chemotherapy sensitivity more than E2F4 knock-down alone. In normal intestinal crypt cells E2F4 was dispensable for chemotherapy resistance. ChIP-seq and RNA-seq experiments revealed that LDHA is a key downstream target of E2F4. LDHA knock-down sensitizes cancer cells to chemotherapy. High LDHA expression in tumor tissues was an independent poor prognostic factor in colorectal cancer patients (n=466), as well as in non-small cell lung cancer (n=1,926) and breast cancer (n=3,554). Thus, the E2F4/p107-LDHA pathway represents a novel therapeutic target to overcome chemotherapy resistance in CSCs.

Abstract
BACKGROUND Several studies have reported that colchicine attenuated the infarct size and inflammation in acute myocardial infarction (MI). However, the sustained benefit of colchicine administration on survival and cardiac function after MI is unknown. It was hypothesized that the short-term treatment with colchicine could improve survival and cardiac function during the recovery phase of MI.Methods and Results:MI was induced in mice by permanent ligation of the left anterior descending coronary artery. Mice were then orally administered colchicine 0.1 mg/kg/day or vehicle from 1 h to day 7 after MI. Colchicine significantly improved survival rate (colchicine, n=48: 89.6% vs. vehicle, n=51: 70.6%, P<0.01), left ventricular end-diastolic diameter (5.0±0.2 vs. 5.6±0.2 mm, P<0.05) and ejection fraction (41.5±2.1 vs. 23.8±3.1%, P<0.001), as assessed by echocardiogram compared with vehicle at 4 weeks after MI. Heart failure development as pulmonary edema assessed by wet/dry lung weight ratio (5.0±0.1 vs. 5.5±0.2, P<0.01) and B-type natriuretic peptide expression in the heart was attenuated in the colchicine group at 4 weeks after MI. Histological and gene expression analysis revealed colchicine significantly inhibited the infiltration of neutrophils and macrophages, and attenuated the mRNA expression of pro-inflammatory cytokines and NLRP3 inflammasome components in the infarcted myocardium at 24 h after MI. CONCLUSIONS Short-term treatment with colchicine successfully attenuated pro-inflammatory cytokines and NLRP3 inflammasome, and improved cardiac function, heart failure, and survival after MI.

Abstract
Methylmalonic acidemia (MMA) is an autosomal recessive disorder that can be classified into two types: (1) vitamin B12-responsive and (2) vitamin B12-non-responsive. In MMA cases with long-term survival, renal failure is often a problem, and timing for kidney transplantation for MMA is controversial. We encountered a vitamin B12-non-responsive MMA case for which regular hemodialysis for renal failure was initiated; the patient was 16 years old when she first received regular hemodialysis and 35 years old when she developed pulmonary artery hypertension (PAH). PAH can complicate regular hemodialysis; however, PAH in this case was considered to be a complication of MMA because it was responsive to medical treatment and reversible. In this report, we discuss the role of regular hemodialysis in MMA and the causal relationship between MMA and regular hemodialysis for PAH.

Abstract
Arterial insufficiency of the foot was examined by radioisotope study with intravenous administration of thallium-201. We observed the immediate distri bution during postocclusive reactive hyperemia and the redistribution in the foot after a 3 hours interval. Seventy-seven feet were examined: 18 normal feet, 24 feet with claudication, 31 feet with rest pain or ischemic ulcers, 4 feet with diabetic ulcers. The distribution index (D.I.), which defined the ratio of uptake counts of the immediate distribution to those of the redistribution, was of use to evaluate quantitively the degree of ischemia. Using these parameters to assess the therapeutic effects, 23 feet with ischemic ulcers were examined before and after treatment.: 5 feet with arterial reconstruction, 4 feet with lumbar sympa thectomy, 14 feet undergoing medical treatment. The effect index (E.I.) was defined as the ratio of the D.I. after treatment to before treatment. When the E.I. value was more than 1.0, 18 of 20 ischemic ulcers were improved and two were unchanged whereas all four ulcers with the E.I. value less than 1.0 became worse. The D.I. is a reliable indicator to estimate the degree of ischemia and the E.I. is of use to predict therapeutic effect particularly following lumbar sympa thectomy or medical treatment, which are frequently difficult to be evaluated by other noninvasive diagnostic methods.

Abstract
We performed 167 femoropopliteal bypass surgeries in 151 patients (95 patients underwent above-knee bypass and 56 below-knee bypass) from December 1985 to December 2000 with the use of prosthetic graft or autologous vein graft. We compared primary patency rates between age, sex, graft material, distal anastomotic site and severity of ischemia, considering their survival rates to elucidate the long-term outcome of above-knee and below-knee femoropopliteal bypass. The 10 year patency rate for above-knee bypass was 47.4%, compared to 36.9% for below-knee ( p < 0.01). Better results were found after bypass surgery for claudicants than for critical ischemia ( p < 0.05). With regard to graft material and age categories, there were unexpectedly no statistical differences in either above-knee or below-knee anastomosis. The survival rate at 10 years in claudicants was 51.2%, compared to 15.9% with critical ischemia ( p < 0.01). Mortality was much influenced by ischemic heart disease ( p < 0.002) and the age of patient ( p < 0.05). The results after above-knee bypass had comparable patency, whereas the results after below-knee bypass were disappointing. Below-knee arterial reconstruction for claudicants should be carefully considered and might be recommended only to patients with critical ischemia.

Abstract
BACKGROUND Endothelial dysfunction plays a crucial role in heart failure (HF), but the association between peripheral microvascular endothelial function assessed by reactive hyperemia peripheral arterial tonometry (RH-PAT) and prognosis remains unknown in HF with reduced left ventricular (LV) ejection fraction (HFREF). We prospectively investigated the association between peripheral microvascular endothelial function and HF-related near-future cardiovascular outcomes in HFREF patients. METHODS AND RESULTS The 362 HFREF patients (LVEF <50%) were followed for HF-related events (composite of cardiovascular death and HF hospitalization) up to 3 years. A natural logarithmic-scaled RH-PAT index (Ln-RHI) was obtained for each patient. A total of 82 HF-related events were recorded. The lower-RHI group (Ln-RHI ≤0.49, median) experienced a higher rate of HF-related events compared with the higher-RHI group by Kaplan-Meier analysis (30.9% vs. 14.4%, log-rank test: P<0.001). Multivariable Cox hazard analysis identified Ln-RHI as an independent predictor for HF-related events (per 0.1, hazard ratio: 0.84, 95% confidence interval: 0.75-0.95, P=0.005). Adding Ln-RHI to the Meta-analysis Global Group in Chronic HF risk score (MAGGICs) and Seattle Heart Failure Model (SHFM), powerful prognostic predictors of HF, significantly improved the net reclassification index (MAGGICs: 20.11%, P=0.02, SHFM: 24.88%, P<0.001), and increased the C-statistics for prediction of HF-related events (MAGGICs+Ln-RHI: from 0.612 to 0.670, SHFM+Ln-RHI: from 0.662 to 0.695). CONCLUSIONS Peripheral microvascular endothelial dysfunction assessed by RH-PAT was associated with future HF-related events in HFREF.

Abstract
OBJECTIVE Mitochondrial dysfunction plays an important role in cellular senescence and impaired function of vascular endothelium, resulted in cardiovascular diseases. Telmisartan is a unique angiotensin II type I receptor blocker that has been shown to prevent cardiovascular events in high risk patients. AMP-activated protein kinase (AMPK) plays a critical role in mitochondrial biogenesis and endothelial function. This study assessed whether telmisartan enhances mitochondrial function and alters cellular functions via AMPK in human coronary artery endothelial cells (HCAECs). METHODS AND RESULTS In cultured HCAECs, telmisartan significantly enhanced mitochondrial activity assessed by mitochondrial reductase activity and intracellular ATP production and increased the expression of mitochondria related genes. Telmisartan prevented cellular senescence and exhibited the anti-apoptotic and pro-angiogenic properties. The expression of genes related anti-oxidant and pro-angiogenic properties were increased by telmisartan. Telmisartan increased endothelial NO synthase and AMPK phosphorylation. Peroxisome proliferator-activated receptor gamma signaling was not involved in telmisartan-induced improvement of mitochondrial function. All of these effects were abolished by inhibition of AMPK. CONCLUSIONS Telmisartan enhanced mitochondrial activity and exhibited anti-senescence effects and improving endothelial function through AMPK in HCAECs. Telmisartan could provide beneficial effects on vascular diseases via enhancement of mitochondrial activity and modulating endothelial function through AMPK activation.

Abstract
Background Pentraxin 3 (PTX3) is a novel inflammatory marker produced by various cell types including those of the vasculature and the heart. The relationship between inflammatory markers and prognosis of patients with heart failure with normal ejection fraction (HFNEF) remains unknown. We investigated whether plasma PTX3 levels can predict future cardiovascular events in patients with HFNEF. Methods and Results Plasma PTX3, high‐sensitivity C‐reactive protein, and B‐type natriuretic peptide levels were measured prospectively in 360 stable patients with HFNEF. The subsequent incidence of cardiovascular events, including cardiovascular death, nonfatal myocardial infarction (MI), unstable angina pectoris, nonfatal ischemic stroke, hospitalization for heart failure decompensation, and coronary revascularization, was determined. During a mean 30‐month follow‐up, 106 patients experienced cardiovascular events. These events were more frequent in patients with high plasma PTX3 levels (>3.0 ng/mL) than low levels (≤3.0 ng/mL). Multivariable Cox hazard analysis showed that PTX3 (hazard ratio: 1.16; 95% CI: 1.05 to 1.27; P<0.01) and B‐type natriuretic peptide (hazard ratio: 1.08; 95% CI: 1.03 to 1.14; P<0.001), but not high‐sensitivity C‐reactive protein levels, were significant predictors of future cardiovascular events. Multivariable Cox analysis with the forced inclusion model, including 5 previously identified prognostic factors, found that PTX3 was a significant predictor of cardiovascular events (hazard ratio: 1.16; 95% CI: 1.06 to 1.27; P<0.01). The C‐statistics for cardiovascular events substantially increased from 0.617 to 0.683 when PTX3 was added to the 5 previously identified prognostic factors. Conclusions High plasma PTX3 levels, but not other inflammatory markers, are correlated with future cardiovascular events in patients with HFNEF. PTX3 may be a useful biomarker for assessment of risk stratification in HFNEF. Clinical Trial Registration URL: http://www.umin.ac.jp; Unique identifier: UMIN000002170.

Abstract
Background Endothelial dysfunction is a key component of vascular vulnerability. Reactive hyperemia index (RHI), as assessed by the peripheral arterial tonometry, can noninvasively evaluate endothelial function. This study was designed to determine the additional prognostic value of endothelial function to the Synergy Between PCI With Taxus and Cardiac Surgery Score (SYNTAXsc) and the Framingham Risk Score (FRS) in predicting cardiovascular events in high‐risk patients. Methods and Results We undertook a two‐center prospective study in 528 stable patients at high‐risk for cardiovascular events from the years 2006–2011. The RHI was measured before coronary angiography and coronary complexity was assessed by SYNTAXsc. After optimal therapies including coronary revascularization, there was follow‐up with patients until August 2012. Cardiovascular events consist of cardiovascular death, myocardial infarction, unstable angina, ischemic stroke, coronary revascularization, heart failure‐induced hospitalization, aortic disease, and peripheral arterial disease. During 1468 person‐years of follow‐up, 105 patients developed cardiovascular events. Multivariate Cox proportional hazards analysis identified B‐type natriuretic peptide (BNP), SYNTAXsc, and RHI as independent cardiovascular event predictors (hazard ratio [95% confidence interval]: natural logarithm of BNP per 0.1: 1.019 [1.002 to 1.037]; P=0.023, SYNTAXsc per tertile: 2.426 [1.825 to 3.225]; P<0.0001, RHI per 0.1: 0.761 [0.673 to 0.859]; P<0.0001). When RHI was added to the FRS, BNP, and SYNTAXsc, net reclassification index was significantly improved (27.5%; P<0.0001), with a significant increase in the C‐statistic (from 0.728 [0.679 to 0.778] to 0.766 [0.726 to 0.806]; P=0.031). Conclusions Advanced endothelial dysfunction significantly correlated with near future cardiovascular events in high‐risk patients. This physiological vascular measurement improved risk discrimination when added to the FRS, BNP, and SYNTAXsc. Clinical Trial Registration URL: clinicaltrials.gov (http://www.clinicaltrials.gov).

Abstract
BACKGROUND Dual antiplatelet therapy with aspirin and clopidogrel is widely used in patients with coronary stents. High residual platelet reactivity (high RPR) after dual antiplatelet therapy is associated with increased cardiovascular events. Endothelial function could affect platelet reactivity in vivo. We hypothesized that endothelial dysfunction could be associated with high RPR after dual antiplatelet therapy in patients with stable coronary artery disease. METHODS AND RESULTS We screened patients with stable coronary artery disease for cytochrome P450 (CYP) 2C19 genotypes and enrolled 103 patients who lacked CYP2C19*2 or *3 loss-of-function allele to minimize the effect of this gene on high RPR. All patients received aspirin (100 mg/d) and clopidogrel (75 mg/d for long-term treatment or a loading dose of 300 mg) before the following tests. Platelet aggregability was assessed as P2Y12 reaction unit using the VerifyNow System. High RPR was defined as P2Y12 reaction unit ≥ 230. Peripheral endothelial function was expressed as reactive hyperemia index using reactive hyperemia peripheral arterial tonometry. Fifty-three patients exhibited high RPR. High RPR patients were significantly older, had higher levels of B-type natriuretic peptide, and were predominantly hypertensive compared with non-high RPR patients. Reactive hyperemia index was significantly lower in high RPR patients (0.46 ± 0.15) compared with non-high RPR patients (0.61 ± 0.18; P<0.001). Linear regression analysis demonstrated significant negative correlation between reactive hyperemia index and P2Y12 reaction unit (r=-0.32; P=0.001). Multivariable logistic regression analysis identified reactive hyperemia index as an independent and significant determinant of high RPR (odds ratio, 0.55; 95% confidence interval, 0.39-0.78; P=0.001). CONCLUSIONS In patients with stable coronary artery disease, endothelial function was significantly impaired in high RPR patients. Endothelial dysfunction is independently correlated with high RPR after dual antiplatelet therapy. CLINICAL TRIAL REGISTRATION URL http://www.umin.ac.jp/ctr. Unique identifier: UMIN000008239.

Abstract
Background Cardiac troponin is a specific biomarker for cardiomyocyte necrosis in acute coronary syndromes. Troponin release from the coronary circulation remains to be determined because of the lower sensitivity of the conventional assay. We sought to determine basal and angina-induced troponin release using a highly sensitive troponin assay. Methods and Results The cardiac troponin T levels in serum sampled from the peripheral vein (PV), the aortic root (AO), and the coronary sinus (CS) were measured in 105 consecutive stable patients with coronary risk factor(s) and suspected coronary artery disease (CAD) and in 33 patients without CAD who underwent an acetylcholine provocation test. At baseline, there was a significant increase in the troponin levels from AO [9.0 (6.4, 13.1) pg/mL for median (25th, 75th percentiles)] to CS [10.3 (7.3, 15.5) pg/mL, p<0.001] in 96 (91.4%) patients and the difference was 1.1 (0.4, 2.1) pg/mL, which reflected basal transcardiac troponin release (TTR). TTR was positively correlated with PV levels (r = 0.22, p = 0.03). Male sex, left ventricular hypertrophy determined by echocardiography, T-wave inversion, and CAD correlated with elevated TTR defined as above: median, 1.1 pg/mL. A significant increase in TTR was noted in 17 patients with coronary spasms [0.6 (0.2, 1.2) pg/mL, p<0.01] but not in 16 patients without spasms [0.0 (−0.5, 0.9) pg/mL, p = 0.73] after the acetylcholine provocation. Conclusion Basal TTR in the coronary circulation was observed in most of the patients with suspected CAD and risk factor(s). This sensitive assay detected myocardial ischemia-induced increases in TTR caused by coronary spasms.

Abstract
BACKGROUND Dipeptidyl peptidase 4 (DPP4) inhibitors are used for treatment of diabetes mellitus (DM). We hypothesized that sitagliptin, a DPP4-inhibitor, could improve endothelial dysfunction in DM patients with coronary artery disease (CAD). METHODS AND RESULTS The 40 patients with CAD and uncontrolled DM, aged 68.7±9.4 years (mean±standard deviation) (50% males, hemoglobin A1c [HbA1c] 7.4±1.0%) were assigned to either additional treatment with sitagliptin (50 mg/day, n=20) or aggressive conventional treatment (control, n=20) for 6 months. Endothelial function was assessed by the reactive hyperemia peripheral arterial tonometry index (RHI). The clinical characteristics at baseline were not different between the groups. After treatment, fasting blood glucose and insulin levels, and lipid profiles were not different between the groups. HbA1c levels significantly improved similarly in both groups. The percent change in RHI was greater in the sitagliptin group than in the control group (62.4±59.2% vs. 15.9±22.0%, P<0.01). Furthermore, treatment with sitagliptin resulted in a significant decrease in the high-sensitivity C-reactive protein (hsCRP) level, but no such change was noted in the control group. Linear regression analysis demonstrated a significant negative relation between changes in RHI and hsCRP, but not between RHI and HbA1c. CONCLUSIONS Sitagliptin significantly improved endothelial function and inflammatory state in patients with CAD and uncontrolled DM, beyond its hypoglycemic action. These findings suggest that sitagliptin has beneficial effects on the cardiovascular system in DM patients.

BACKGROUND AND PURPOSE The prevalence and topography of small hypointense foci suggesting microbleeds on 3T SWI in various types of dementia have not been systematically investigated. The purpose of this study was to determine the prevalence and topography of SHF on 3T SWI in patients with different dementia subtypes. MATERIALS AND METHODS We included 347 consecutive patients (217 women, 130 men; age range, 42-93 years; mean age, 74 years) who attended our memory clinic and underwent 3T SWI. They were divided into 6 groups: subjective complaints, MCI, AD, DLB, VaD, and FTLD. Two neuroradiologists evaluated the number and location of SHF on SWIs. Statistical analyses were performed to evaluate inter- and intragroup differences. RESULTS Of the 347 patients, 160 (46.1%) exhibited at least 1 small hypointense focus. This was true in 86% with VaD, 54% with DLB, 48% with AD, 41% with MCI, 27% with FTLD, and 22% with subjective complaints. With the subjective complaints group as a reference, the odds ratio adjusted by age, sex, and arterial hypertension was 9.2 (95% CI, 2.0-43.6) for VaD; 5.4 (95% CI, 1.2-24.3) for AD; 3.1 for DLB (95% CI, 1.1-8.8); 2.0 for MCI (95% CI, 0.5-8.1); and 1.5 for FTLD (95% CI, 0.4-5.4). There was a significant lobar predilection for AD, DLB, and FTLD groups (P < .05). CONCLUSIONS On 3T SWI, patients with VaD, AD, and DLB manifested a high SHF prevalence. In patients with AD, DLB, and FTLD, the SHF exhibited a lobar predilection.

Abstract
Background Angina without significant stenosis, or nonobstructive coronary artery disease, attracts clinical attention. Microvascular coronary artery spasm (microvascular CAS) can cause nonobstructive coronary artery disease. We investigated the clinical features of microvascular CAS and the therapeutic efficacy of calcium channel blockers. Methods and Results Three hundred seventy consecutive, stable patients with suspected angina presenting nonobstructive coronary arteries (<50% diameter) in coronary angiography were investigated with the intracoronary acetylcholine provocation test, with simultaneous measurements of transcardiac lactate production and of changes in the quantitative coronary blood flow. We diagnosed microvascular CAS according to lactate production and a decrease in coronary blood flow without epicardial vasospasm during the acetylcholine provocation test. We prospectively followed up the patients with calcium channel blockers for microvascular coronary artery disease. We identified 50 patients with microvascular CAS who demonstrated significant impairment of the endothelium-dependent vascular response, which was assessed by coronary blood flow during the acetylcholine provocation test. Administration of isosorbide dinitrate normalized the abnormal coronary flow pattern in the patients with microvascular CAS. Multivariate logistic regression analysis indicated that female sex, a lower body mass index, minor–borderline ischemic electrocardiogram findings at rest, limited–baseline diastolic-to-systolic velocity ratio, and attenuated adenosine triphosphate–induced coronary flow reserve were independently correlated with the presence of microvascular CAS. Receiver-operating characteristics curve analysis revealed that the aforementioned 5-variable model showed good correlation with the presence of microvascular CAS (area under the curve: 0.820). No patients with microvascular CAS treated with calcium channel blockers developed cardiovascular events over 47.8±27.5 months. Conclusions Microvascular CAS causes distinctive clinical features and endothelial dysfunction that are important to recognize as nonobstructive coronary artery disease so that optimal care with calcium channel blockers can be provided.

Abstract
BACKGROUND Early detection would be one of the most effective means to improve the outcome of renal cell carcinoma (RCC). We searched for a new plasma marker for RCC using a label-free quantitative shotgun proteomics method. METHODS Plasma proteins were digested by trypsin, and the resulting peptides were analyzed by 2-Dimensional Image Converted Analysis of Liquid chromatography mass spectrometry (2DICAL). An identified biomarker candidate was subjected to validation using the Amplified Luminescent Proximity Homogeneous Assay (AlphaLISA). RESULTS Among a total of 23,407 independent MS peaks, we found that the mean intensity of 59 peaks significantly differed between 20 clear cell RCC patients and 20 healthy controls. MS/MS spectra from 16 of the 59 peaks matched the amino acid sequences of the fibronectin 1 (FN1) gene product. The increased plasma level of FN1 in RCC patients was validated in a cohort of in 77 patients and 130 healthy controls (p < 0.0001). CONCLUSIONS The FN1 is considered to be a promising biomarker candidate for clear cell RCC. Furthermore, AlphaLISA is an alternate to the conventional enzyme-linked immunosorbent assay and should prove useful for the rapid validation of biomarker candidates.
