Abstract
PURPOSE This study evaluated treatment patterns and clinical outcomes among patients with metastatic triple-negative breast cancer (mTNBC) in real-world clinical settings in Japan. METHODS The treatment patterns, time to next treatment or death (TTNTD), time to treatment discontinuation, adverse events of interest, and medical costs of treating patients with mTNBC in first-, second-, and third-line settings were investigated using data of patients meeting the inclusion criteria between January 2017 and March 2022 in a Japanese medical claims database. The treatment regimens for mTNBC were defined according to the Japanese Breast Cancer Society Clinical Practice Guidelines. RESULTS In this study, 2236 patients with mTNBC (median age 66.0 years; 99.8% female) were included in the first-line cohort. Of these, 46.6% and 20.8% were included in the second- and third-line cohorts, respectively. The two most frequently used treatments were capecitabine (19.1%) and S-1 (tegafur-gimeracil-oteracil) (14.5%) in the first-line cohort, eribulin (18.3%) and bevacizumab/paclitaxel (14.4%) in the second-line cohort, and eribulin (19.4%) and bevacizumab/paclitaxel (17.5%) in the third-line cohort. The TTNTD shortened as the line of therapy progressed (median 8.0, 6.5, and 5.2 months for the first-, second-, and third-line treatments, respectively). Nausea/vomiting and neutropenia/leukopenia occurred in 62.8% and 18.3% of all patients, respectively. The medical total costs per day were 6.7, 10.2, and 12.9 thousand yen during the first-/second-/third-line treatments, respectively. CONCLUSION This study provides insight into current treatment patterns for mTNBC in Japan. The cost-benefit balance worsens with later-line treatment and a high unmet need for mTNBC drug treatment remains.

Abstract
We report the case of a 40-year-old woman, with endometriosis, who presented with a history of foot drop and cyclic sensory disturbance of the right lower limb. She was initially diagnosed with lumbar disc herniation. Neurological examination revealed muscle weakness and sensory disturbance associated with the right sciatic nerve. Nerve conduction studies revealed a low amplitude sensory nerve action potential in the right superficial fibular and sural nerves. Pelvic magnetic resonance imaging revealed an endometriotic cyst in the right ovary, and an endometriotic lesion extending from the right ovary, pelvis, and the right sciatic nerve. Though her symptoms moderately improved with hormonal therapy, the foot drop remained. Our case and previous reports suggest that endometriosis with sciatic neuropathy shows cyclic neurological symptoms during menstruation, with a higher incidence on the right extremity. This case highlights that endometriosis should be considered as a potential differential diagnosis in women of reproductive age with sciatic nerve dysfunction. Its cyclic neurological manifestations should be investigated.

Abstract
PURPOSE/OBJECTIVE(S) The effectiveness of stereotactic body radiation therapy (SBRT) for hepatocellular carcinoma (HCC) has been shown in many studies and its therapeutic effect is similar to radiofrequency ablation (RFA). However, many of these studies were done in combination with transcatheter chemoembolization (TACE), for recurrent HCC, or on a small scale. To better understand the specific outcomes of SBRT for HCC, we conducted a multicenter retrospective analysis of SBRT for previously untreated initial HCC at Japanese Society of Clinical Oncology (JCOG) member hospitals. MATERIALS/METHODS Patientswho underwent SBRT for HCC at JCOG member hospitals between July 2013 and December 2017 and met the following eligibility criteria were included: (1) initial HCC; (2) ≤ 3 nodules, ≤ 5 cm in diameter; (3) a Child-Pugh (CP) score of A or B; and (4) unsuitability for or refusal of standard treatment, such as surgery, transplantation, RFA and TACE. We evaluated the overall survival (OS), recurrence-free survival (RFS) which was defined as the first instance of intra-hepatic recurrence after SBRT, disease-specific survival (DSS) using Kaplan-Meier analysis. Using Grey's test, patients who died of other diseases were analyzed as competing risks to estimate the cumulative incidence of local recurrence (CLR). Adverse events directly related to SBRT also analyzed using Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0). RESULTS Seventy-three patients with 79 lesions from 14 hospitals were analyzed. The median age was 77 years (range; 50-89 years), and the median tumor size was 23 mm (range; 6-50 mm). The median radiation dose was 40 Gy (range; 35-60 Gy) in five fractions (range; 4-8). The median follow-up period was 45 months (range; 0-103 months). There were three cases where follow-up was not possible due to unexpected events unrelated to SBRT, while the remaining 70 patients were successfully followed for at least six months. The 2 and 3year OS, RFS, DSS, and CLR rates were 84.3% (95% CI: 75.8-92.8%) and 69.9% (95% CI: 58.7-81%), 67.5% (95% CI: 56.0-79.0%) and 57.9% (95% CI: 45.2-70.5%), 95.1% (95% CI:89.7-100%)/87.6% (95% CI:78.8-96.3%), and 11.4% (95% CI: 5.3-20.0%) and 20.0% (95% CI: 11.2-30.5%), respectively. Four cases (5.5%) of adverse events of grade 3 or higher were reported: one case of grade 3 laboratory toxicities, one case of grade 3 liver failure, one case of grade 3 portal tumor thrombosis, and one case of grade 4 duodenal ulcer. No grade 5 toxicities were observed. CONCLUSION The results of our study demonstrate that SBRT for HCC is highly effective in achieving local control and is safe to administer. In addition, survival outcomes are favorable. SBRT is a promising treatment modality, especially for small HCCs for that is not suitable for standard treatment.

Abstract
OBJECTIVES To investigate the usefulness of harmonized 18F-FDG-PET/CT parameters for predicting the postoperative recurrence and prognosis of oral tongue squamous cell carcinoma (OTSCC). METHODS We retrospectively analyzed the cases of 107 OTSCC patients who underwent surgical resection at four institutions in Japan in 2010-2016 and evaluated the harmonized PET parameters of the maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) for the primary tumor as the pSUVmax, pMTV, and pTLG. For lymph node metastasis, we used harmonized PET parameters of nodal-SUVmax, nodal-total MTV (tMTV), and nodal-total TLG (tTLG). The associations between the harmonized PET parameters and the patients' relapse-free survival (RFS) and overall survival (OS) were evaluated by the Kaplan-Meier method and Cox proportional hazard regression analysis for model 1 (preoperative stage) and model 2 (preoperative + postoperative stages). RESULTS The harmonized SUVmax values were significantly lower than those before harmonization (p=0.012). The pSUVmax was revealed as a significant preoperative risk factor for RFS and OS. Nodal-SUVmax, nodal-tMTV, and nodal-tTLG were significant preoperative risk factors for OS. The combination of pSUVmax + nodal-SUVmax significantly stratified the patients into a low-risk group (pSUVmax <3.97 + nodal-SUVmax <2.85 or ≥2.85) and a high-risk group (pSUVmax ≥3.97 + nodal-SUVmax <2.85 or pSUVmax ≥3.97 + nodal-SUVmax ≥2.85) for recurrence and prognosis (RFS: p=0.001; OS: p<0.001). CONCLUSIONS The harmonized pSUVmax is a significant prognostic factor for the survival of OTSCC patients. The combination of pSUVmax and nodal-SUVmax identified OTSCC patients at high risk for recurrence and poor prognosis at the preoperative stage.

Abstract
Coral reefs in the Central Indo-Pacific region comprise some of the most diverse and yet threatened marine habitats. While reef monitoring has grown throughout the region in recent years, studies of coral reef benthic cover remain limited in spatial and temporal scales. Here, we analysed 24,365 reef surveys performed over 37 years at 1972 sites throughout East Asia by the Global Coral Reef Monitoring Network using Bayesian approaches. Our results show that overall coral cover at surveyed reefs has not declined as suggested in previous studies and compared to reef regions like the Caribbean. Concurrently, macroalgal cover has not increased, with no indications of phase shifts from coral to macroalgal dominance on reefs. Yet, models incorporating socio-economic and environmental variables reveal negative associations of coral cover with coastal urbanisation and sea surface temperature. The diversity of reef assemblages may have mitigated cover declines thus far, but climate change could threaten reef resilience. We recommend prioritisation of regionally coordinated, locally collaborative long-term studies for better contextualisation of monitoring data and analyses, which are essential for achieving reef conservation goals.

Abstract
BACKGROUND/AIM Sarcopenia has an adverse effect on postoperative complications and prognoses in head and neck cancer. This study focused on hypopharyngeal and laryngeal cancer patients with sarcopenia and analyzed the body composition following treatment when the larynx was preserved and when total laryngectomy was performed to examine the usefulness of laryngectomy. PATIENTS AND METHODS We retrospectively reviewed 88 primary hypopharyngeal and laryngeal cancer patients aged 65 years or older with cT2N0M0 or higher who visited our department. RESULTS There were no significant differences in the 3-year overall survival rate and the 1-year local control rate between the laryngeal preservation group and laryngectomy group. The average change one year following treatment in the laryngeal preservation group, when compared to prior to treatment, was a significant decrease in the body weight (BW) of -0.035, skeletal muscle mass (SMM) of -0.030, skeletal muscle mass index (SMI) of -0.026, body mass index (BMI) of -0.034, and grip strength (GS) of -0.066. The average change one year following treatment in the laryngectomy group, compared with prior to treatment, was an increase in BW of +0.028, SMM of +0.026, SMI of +0.008, BMI of +0.032, and GS of +0.026. Although no changes in serum biochemical testing after treatment were observed in the laryngeal preservation group, albumin, transferrin, and transthyretin all exhibited significant improvement or a tendency toward improvement in the laryngectomy group. The patients with sarcopenia before treatment in the laryngeal preservation group had a significantly higher incidence of aspiration pneumonia. CONCLUSION The presence or absence of sarcopenia before starting treatment is considered to be an index for selecting total laryngectomy.

Abstract
Abstract
Introduction: Combination anti-CTLA-4 antibody (Ab) + anti-PD-1 Ab is approved in multiple cancer types and has improved clinical outcomes. In addition, atezolizumab + bevacizumab combination therapy is approved for unresectable hepatocellular carcinoma. Given the rapid changes in the therapeutic landscape, it is important to investigate effective treatments for people with prior ICI-based combination therapy. E7386 modulates Wnt/β-catenin signaling, and a phase 1 study in combination with LEN (a receptor tyrosine kinase inhibitor that mainly targets both VEGFR and FGFR), in people with solid tumors (NCT04008797) is ongoing. In this study, we examined the antitumor activity of the combination of E7386 + LEN, with either prior anti-CTLA-4 Ab + anti-PD-1 Ab or anti-PD-1 Ab + aflibercept (a soluble decoy receptor against VEGF), in the mouse lung tumor KLN 205 model.
Methods: Antitumor activity of E7386 (25 or 50 mg/kg), LEN (3 mg/kg), and the combination, was evaluated in the KLN 205 model (orally, once daily x 14 days), with or without prior treatments of either anti-CTLA-4 Ab (0.2 mg/head, weekly x 3, intraperitoneally [ip]) + anti-PD-1 Ab (0.2 mg/head, weekly x 3, ip)─ie, CTLA-4 + PD-1; or aflibercept (5 mg/kg) + anti-PD-1 Ab (0.2 mg/head, twice a week x 2, ip)─ie, AFL + PD-1. Mice with relatively rapid-growing tumors and prior treatments were given E7386, LEN, and their combination. RNA-seq analyses were conducted by using tumor tissues collected from mice one day after the prior treatment period or without treatment to analyze gene-expression alterations with prior treatments.
Results: In the mouse model without prior treatments, LEN had clear antitumor activity. E7386 had limited antitumor activity as a monotreatment. E7386 + LEN had superior antitumor activity vs LEN in a dose-dependent manner. In addition, E7386 + LEN had superior antitumor activity to each single treatment despite either prior CTLA-4 + PD-1 or AFL + PD-1. E7386 + LEN with prior CTLA-4 + PD-1 had equivalent antitumor activity to LEN without prior treatments. Conversely, E7386 + LEN with prior AFL + PD-1 had strong antitumor activity, including marked tumor regression, compared to both LEN alone and E7386 + LEN without prior treatments. RNA-seq analyses showed that intratumoral Axin2, a target gene in the canonical Wnt-signaling pathway, was upregulated with prior AFL + PD-1—suggesting a potential activation of the Wnt-signaling pathway.
Conclusion: E7386 + LEN combination shows antitumor activity in the mouse KLN 205 lung tumor model when there is prior ICI-based (CTLA-4 + PD-1 or AFL + PD-1) combination treatment. Further, E7386 + LEN shows enhanced antitumor activity with prior AFL + PD-1; possibly due to activation of Wnt-signaling pathway during prior treatments.

Abstract
Targeted therapy with a combination of dabrafenib and trametinib has been developed and widely used for treatment of melanoma. However, data regarding its safety and efficacy in Japanese patients with malignant melanoma are limited. A post-marketing surveillance (PMS) study was conducted to investigate the safety and efficacy of combination therapy in a Japanese clinical setting with a surveillance period of June 2016 to March 2022; 326 patients with unresectable malignant melanoma with BRAF mutation were enrolled. The interim results were published in July 2020. Herein, we report the results of the final analysis based on the data collected until the completion of the PMS study. The safety analysis population included 326 patients, the majority of whom had stage IV disease (79.14%) and Eastern Cooperative Oncology Group performance status 0 or 1 (85.28%). All patients were treated with the approved dose of dabrafenib, while 99.08% were treated with the approved dose of trametinib. Adverse events (AEs) occurred in 282 patients (86.50%) and the major AEs (incidence ≥5%) were pyrexia (47.85%), malignant melanoma (33.44%), hepatic function abnormal (9.82%), rash and blood creatine phosphokinase increased (8.59% each), malaise (6.44%), nausea (5.52%), and diarrhea and rhabdomyolysis (5.21% each). The incidences rates of adverse drug reactions of safety specifications were 45.71% for pyrexia, 15.95% for hepatic impairment, 12.58% for rhabdomyolysis, 4.60% for cardiac disorders, and 3.07% for eye disorders. In the efficacy analysis population of 318 patients, the objective response rate was 58.18% (95% confidence interval [CI] 52.54%-63.66%). The progression-free survival rates at 90, 180, and 360 days were 88.14% (95% CI 84.00%-91.26%), 69.53% (63.85%-74.50%), and 52.07% (45.71%-58.03%), respectively. Consistent with previous interim results, no new safety or efficacy concerns were observed in this final analysis of a PMS study conducted in a Japanese real-world clinical setting.

Abstract
The identification of biologically active target compounds and their binding proteins is important in mechanism-of-action studies for drug development. Additionally, the newly discovered binding proteins provide unforeseen ideas for novel drug discovery and for subsequent structural transformation to improve target specificity. Based on the lead and final candidate compounds related to the type 5 phosphodiesterase (PDE5) inhibitor E4021, we designed chemical probes and identified their target proteins by the affinity chromatography approach. Aldehyde dehydrogenase family 1 member A3 (ALDH1A3), currently reported as a cancer stem cell target, was clearly isolated as a binding protein of the lead 'immature' inhibitor probe against PDE5. In the early derivatization to the closely related structure, Compound 5 (ER-001135935) was found to significantly inhibit ALDH1A3 activity. The discovery process of a novel ALDH1A3-selective inhibitor with affinity-based binder identification is described, and the impact of this identification method on novel drug discovery is discussed.

Abstract
106 Background: E7386 is a novel oral anticancer agent that inhibits the binding of β-catenin to its transcriptional co-activator, CBP, thereby modulating Wnt/β-catenin signaling. In preclinical studies, E7386 showed promising activity (eg, modulation of tumor angiogenesis, alteration of the immune microenvironment, and inhibition of tumor growth). At a prior cutoff point for the dose-escalation part of a phase 1 study of E7386 in pts with advanced solid tumors, we reported 2 dose-limiting toxicities (DLTs; both grade 3 decreased appetite) with E7386 160 mg twice daily (BID). Here we describe an update of the dose-escalation part of this phase 1 study—we mainly report updated safety, tolerability, and preliminary efficacy and biomarker results, which led to the inclusion of an additional dose level for investigation in the expansion part of this study. Methods: E7386 was administered orally in escalating doses on a BID continuous schedule in 28-day cycles. Adverse events (AEs) were graded using CTCAE v5.0. Tolerability was judged by DLTs during cycle 1 (C1). Tumor response was assessed every 8 weeks from C1 day (D) 1, or sooner if clinically indicated, and at the end of treatment by investigators using RECIST v1.1. Samples for pharmacokinetic analyses were collected on C1D1 and C1D8; samples for biomarker analyses were collected at protocol-defined time points. To determine the appropriate dose(s) for the expansion part of this study, additional investigation of the dose-escalation part was conducted. Results: As of the data cutoff (DCO) date (30 June 2022), 36 pts (24 men, 12 women; median age, 61.5 y) were enrolled in E7386 dose cohorts (10 to 160 mg BID). Doses were tolerable up to 120 mg BID. The most common treatment-related AEs (all grades; > 10%) were nausea (80.6%), vomiting (58.3%), aspartate aminotransferase increased (16.7%), and alanine aminotransferase increased, decreased appetite, and diarrhea (13.9% each). Nausea and vomiting were well-controlled with antiemetics such as 5HT3 antagonists, except in the 160 mg BID cohort. Two pts with a Wnt-related adenomatous polyposis coli (APC)- mutation (small bowel adenocarcinoma and desmoid tumor) showed a partial response. As of the DCO date, 2 pts (who continued on-treatment as of that date) had received over 1.5 y of E7386 treatment. The preliminary PK analysis showed plasma exposure of E7386 generally increased with an increasing dose over the assessed dose range. FGF21 levels in plasma increased following E7386 administration. Conclusions: E7386 120 mg BID was tolerated and determined as the recommended dose for the expansion part. Based on additional analyses of the dose-escalation part of this study, further investigation of safety, preliminary efficacy, PK, and biomarker analyses of E7386 is ongoing using 2 dose levels (100 and 120 mg BID) in the expansion part. Clinical trial information: NCT03833700 .

Abstract
We report a case of neurogenic pulmonary edema (NPE) caused by middle cerebral artery infarction involving the right insular cortex. Hyperactivity of the insular cortex, which regulates sympathetic function, can cause NPE. The NPE should be considered in the differential diagnosis of dyspneic patients with insular cortex infarction.

Abstract
Finding the shortest paths for packets from sources to destinations in packet-switched communication networks is an inevitable problem in building a future high-speed information society. A routing method with memory information has already been proposed to alleviate the congestion of large volumes of packet flow. This routing method shows a high transmission completion rate even for large volumes of packet flows in communication networks with scale-free properties. However, the method exhibits poor performance for networks with local triangular connections and long distances between nodes. To overcome these problems, in this study, we first enhanced the routing performance of the conventional communication network models by using the betweenness centrality of nodes, which is one of the network centralities that measures the number of shortest paths that pass through each node in the networks. Subsequently, we adaptively changed the transmitting paths of packets by using only local information. Numerical simulations indicated that our routing method performs successfully for various topologies of communication networks by avoiding the congested node, and effectively using the memory information.

Abstract
Introduction Radiation and intra-arterial cisplatin infusion chemotherapy (RADPLAT) for advanced maxillary sinus cancer has accumulated evidence as a treatment with fewer complications and better 5-year survival rates. In this study, we report a case in which pterygoid muscle necrosis occurred 6 months following RADPLAT treatment for maxillary sinus cancer. Case Presentation The 45-year-old woman had a long history of taking immunosuppressants against rheumatoid arthritis (RA) prior to treatment. Although achieving complete response (CR) to RADPLAT, the patient developed trismus (1 fingerbreadth or less) 6 months following treatment. Abscess formation and recurrence were suspected from the imaging findings; however, the biopsy with endoscopy indicated necrotic tissue. Currently, 18 months have passed without cancer recurrence. Although trismus temporarily improved with rehabilitation, the width of the mouth opening is currently a few millimeters, so the patient can only take liquid food. Conclusion Pterygoid muscle necrosis should be recognized as a new major complication.

Abstract
Optical absorption spectra in the visible and near-infrared light were measured for magnetoelectric spin glass Ni_{0.4}Mn_{0.6}TiO_{3} under various field-cooled conditions. Despite the absence of long-range magnetic-dipole order, this spin-glass system exhibits nonreciprocal directional dichroism (NDD) at zero external field after a magnetoelectric field-cooled procedure. This result is distinct from previous studies on NDD in systems with magnetic toroidal moments induced either by long-range magnetic-dipole order or by applying crossed electric and magnetic fields. The present Letter conclusively demonstrates that the observed NDD originates from magnetoelectrically induced ferroic order of magnetic toroidal moments without conventional magnetic-dipole order.

Abstract
Introduction
The electrical pulmonary vein (PV) isolation has been established as a curative therapy for paroxysmal atrial fibrillation (AF). Arctic Front™cryoballoon has been used worldwide for AF cryoablation. Recently, a new cryoballoon, POLARxTM CRYOABLATION system have been introduced, of which material of the balloon is softer and the N2O gas flow rate is higher.
Purpose
The aim was to investigate the procedural parameter and efficacy of POLARx comparing with Arctic Front.
Methods
This retrospective single center study included 101 consecutive patients who underwent paroxysmal AF ablation using cryoballoon at Keio University hospital from April 2021 to March 2022. The procedural data including the cryoballoon temperature and the number and duration of cryoablation were compared between POLARx (POLARx group) and ARCTIC FRONT ADVANCE PRO (AFA group). After the cryoablation, we added the radiofrequency application in order to maximize the isolated area when the voltage was remained inside PV (Figure 1). The necessities of the additional radiofrequency applications were also compared.
Results
In the present study, 64 patients in AFA group and 37 patients in POLARx group were analyzed. POLARx group included younger population and less females (62.8±9.9 vs 67.5±9.4 year of age, P=0.02; 13.5 vs 32.8%, P=0.04). There was no significant difference in comorbidities and examination data such as left atrium diameter or brain natriuretic peptide level. The minimal cryoballoon temperatures reached in POLARx group were lower than AFA group (−59.3±6.2 vs −47.7±7.5°C, P<0.01). No difference was found in the total number and duration of cryoablation and the time to isolate PV (6.1±2.1 vs 5.9±1.6, P=0.69; 790.2±256.1 vs 776.1±235.0 sec, P=0.69; 41.8±21.3 vs 47.1±29.6 sec, P=0.44, respectively). With regard to individual PVs, the total number and duration were tended to be larger at right superior PV in POLARx group (1.9±1.1 vs 1.4±0.7, P=0.01; 231.8±123.8 vs 193.2±83.0 sec, P=0.07), while there was no significant difference at the other PVs. The rate of successful PV isolation by a single cryo-application was not different between AFA and POLARx group (54.3 vs 61.4%, P=0.17). The additional radiofrequency applications were more frequent in AFA group (14.8 vs. 4.9%, P=0.003). There was a significant difference at right inferior PV (32.8 vs 8.1%, P=0.01), while not at left superior PV, left inferior PV and right superior PV (9.4 vs 2.9%, P=0.42; 9.4 vs 5.7%, P=0.71; 7.8 vs 2.7%, P=0.41). Phrenic nerve injury was occurred 1 case in both group and esophageal ulcer was occurred in 1 case in AFA group. No other complication including cardiac tamponade was occurred.
Conclusion
The total number and duration of cryoablation were not significantly different between AFA and POLARx group, except for right superior PV. There was an advantage in largely isolating right inferior PV in POLARx group comparing with AFA group.

Abstract
Abstract
Background
There are significant differences in the prevalence and prognosis of cardiovascular diseases between male and female. We previously reported that catheter ablation (CA) of atrial fibrillation (AF) was less effective in female than male, but whether their history of heart failure influence the recurrence after CA of AF remains still unknown.
Purpose
We sought to clarify sex differences in terms of AF recurrence after RFCA of AF according to the history of heart failure.
Methods
We conducted a large-scale, prospective, multicenter, observational study (Kansai Plus Atrial Fibrillation Registry). We enrolled 5010 consecutive patients who underwent an initial RFCA of AF at 26 centers (64±10 years; 1369 [27.3%] females; non-paroxysmal AF, 35.7%). The median follow-up duration was 2.9 years.
Results
Fourteen % of female had a history of heart failure prior to CA, while 12.8% of male had a history of heart failure at baseline (p=0.29). The 3-year cumulative incidence of AF recurrence after a single procedure was 43.3% in female and 39.0% in male (log rank P=0.0046). In patients with the history of heart failure, AF recurrence rates were 42.2% in female and 45.8% in male (log rank P=0.51). On the other hand, in patients without history of heart failure, more females experienced AF recurrence (female vs. male, 43.5% vs. 38.0%, log rank P=0.001).
The rate of AF recurrence after multiple procedures was higher in female (24.2% vs. 19.6%, log rank P<0.0001). AF recurrence rates were similar between sexes in patients with history of heart failure (female vs. male, 26.0% vs. 26.7%, log rank P=0.86), while AF recurrence rates were higher in female without history of heart failure than those in male (females vs. males, 23.9% vs. 18.5%, log rank P<0.0001).
Conclusion
The Kansai Plus Atrial Fibrillation Registry revealed a distinct sex difference in terms of the AF recurrence after CA of AF. Females had higher recurrence rates compared with males in patients without history of heart failure, while recurrence rates were similar between sexes in patients with history of heart failure.

Abstract
Abstract
Study question
To evaluate the effectiveness of chlormadinone acetate (CMA) for preventing premature LH surge in patients with normal ovarian reserve compared to cetrorelix.
Summary answer
In progestin-primed ovarian stimulation (PPOS) than GnRH antagonist (GnRH-ant), the incidence of premature LH surge was significantly lower, without significant difference in oocyte maturation rate.
What is known already
The GnRH-ant protocol is one of the conventional protocols which has some disadvantages including increased premature LH surge rate and cancelation rate. In recent years, the PPOS protocol has attracted attention as a new ovarian stimulation using progestin as an alternative to GnRH analog for suppressing a premature LH surge, however its efficacy is still controversial. In addition, many studies have investigated the reproductive outcomes of PPOS using medroxy-progesterone acetate or dydrogesterone; however, there are few reports of CMA, an oral progestin, which is inexpensive and widely used in Japan.
Study design, size, duration
This retrospective cohort study was performed in a reproduction center between March 2018 and October 2020 which included 977 Japanese patients with normal ovarian reserve undergoing PPOS with CMA (n = 299), or GnRH antagonist (GnRH-ant) with cetrorelix (n = 608) in their first IVF cycle at the reproduction center. In subgroup analysis, pregnancy outcomes after frozen embryo transfers (FET) between PPOS (n = 284) and GnRH-ant (n = 579) were also compared.
Participants/materials, setting, methods
The inclusion criteria were patients aged < 40 years and AMH ≧ 1.1 ng/mL, who underwent autologous oocyte retrieval in their first IVF cycle with freeze-all strategy. The primary outcome was the incidence of premature LH surge, the secondary outcomes was oocyte maturation rate. To reduce the impact of treatment bias and potential confounding factors, we conducted logistic regression models with inverse-probability-of-treatment weighting (IPTW).
Main results and the role of chance
After IPTW, baseline clinical data were well-balanced between the two groups, including age, AMH, BMI, the duration, type, and cause of infertility, antral follicle count, the history of recurrent spontaneous abortion, and previous IVF attempts. The premature LH surge rate was significantly lower with PPOS (3.1%) compared to GnRH-ant (20.1%) (odds ratio, 0.21; 95% confidence interval, 0.11–0.36). No significant differences were found in total gonadotropin dose (2400IU for PPOS vs 2400IU for GnRH-ant, p = 0.136), the number of oocyte retrieval (n = 15 vs n = 15, p = 0.484), oocyte maturation rate (78.8% vs 77.8%, p = 0.275), fertilization rate (73.0% vs 72.0%, p = 0.412), viable embryo rate per oocyte retrieval (40% vs 40%, p = 0.890), and good quality blastocyst rate (72.0% vs 69.6%, p = 0.092). However, the good quality day-3 embryo rate was significantly lower with PPOS (37.2% vs 49.1%, p < 0.05). There were no differences in the incidence of moderate-to-severe OHSS (0.3% vs 0.7%, p = 0.481). In FET cycles, the pregnancy outcomes, such as implantation rate (43.1 % vs 51.9 %, p = 0.013) and clinical pregnancy rate (46.5% vs 54.7%, p = 0.027) were significantly lower with PPOS, however, no significant differences were found in ongoing pregnancy rate (75.6% vs 80.5%, p = 0.325), and live birth rate (72.4% vs 79.5 %, p = 0.142).
Limitations, reasons for caution
This was a retrospective cohort study conducted in a single center. The participants in this study were limited to Japanese ethnicity. The results need to be validated across different centers and other ethnicities.
Wider implications of the findings
This is the first report assessing the reproductive outcomes on PPOS using CMA, widely used in Japan. The PPOS with CMA significantly suppressed the premature LH surge rate compared to GnRH-ant protocol, without decrease in oocyte maturation rate.

Abstract
Abstract
Lenvatinib is a multiple receptor tyrosine kinase inhibitor and an angiogenesis inhibitor targeting mainly vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF) receptors. In our previous study, we reported that human xenograft tumors sensitive to lenvatinib showed higher microvessel density (“MVD (IHC)”) than relatively resistant tumors in immunohistochemistry (IHC). Although MVD (IHC) is a potential indicator to predict antitumor activity of lenvatinib, available IHC data are limited. Here, we investigated a novel gene expression signature (MVD gene score) calculated from RNA-sequencing (RNA-seq) data that reflects MVD (IHC) and antitumor effect of lenvatinib.
Tumor tissues were collected from 12 mouse syngeneic tumor models followed by RNA-seq. We also stained CD31 in the same tumors and calculated MVD (IHC) score by dividing the number of CD31 positive blood vessels by tumor area. Genes that met the following criteria were selected for MVD gene score calculation: (1) genes that are specifically expressed on endothelial cell cluster in in-house single cell RNA-seq data using Hepa 1-6 mouse hepatocellular carcinoma tumor tissues; (2) well-known angiogenesis markers from literature or genes whose expression show significant correlation with MVD (IHC) in mouse syngeneic tumor models. MVD gene score was calculated as the average of logarithm transformed gene expression values. In order to examine applicability of MVD gene score, we compared MVD (IHC) and MVD gene score to lenvatinib antitumor activities on mouse syngeneic tumors.
We measured MVD (IHC) and computed MVD gene score from RNA-seq data using matched tumor tissues of 12 mouse syngeneic models. MVD gene score was correlated with MVD (IHC). As reported, lenvatinib sensitive tumor models showed higher MVD (IHC) score. They also showed higher MVD gene score calculated from RNA-seq data.
Our newly developed MVD gene score has a potential to predict the antitumor activity of angiogenic inhibitors such as lenvatinib using RNA-seq data in tumor samples. Further validation study is ongoing using various human tumor samples.

Abstract
Background: Malignant neoplasms (MNs) in the head and neck are occasionally hidden in deep neck infections (DNIs) that require emergency treatment, which potentially leads to delayed diagnosis of MNs.Objectives: This study aimed to identify predictive factors that can prevent delays in diagnosing MNs in patients with DNIs.Methods: We retrospectively analysed data from 83 patients admitted to our hospital who were diagnosed with DNIs.Results: Four patients (4.8%) had DNIs veiling MNs in the head and neck. Statistical analyses revealed a significant association (p = .0481) of platelet to albumin ratio (PAR; ≥ 98.9 × 103) with hidden MNs in DNIs. Furthermore, concomitant cervical lymphadenopathy, especially multiple lymphadenopathies and excluding abscesses, was higher in patients with DNIs veiling MNs (p = .0142 and p = .0023, respectively).Conclusions and Significance: The PAR, which can be easily measured and readily detected, was a potential predictive factor. Moreover, performing fine-needle aspiration for lymphadenopathies could help diagnose hidden MNs in DNIs.

Abstract
Combination therapies consisting of immune checkpoint inhibitors plus anti-VEGF therapy show enhanced antitumor activity and are approved treatments for patients with renal cell carcinoma (RCC). The immunosuppressive roles of VEGF in the tumor microenvironment are well studied, but those of FGF/FGFR signaling remain largely unknown. Lenvatinib is a receptor tyrosine kinase inhibitor that targets both VEGFR and FGFR. Here, we examine the antitumor activity of anti-PD-1 mAb combined with either lenvatinib or axitinib, a VEGFR-selective inhibitor, in RCC. Both combination treatments showed greater antitumor activity and longer survival in mouse models versus either single agent treatment, whereas anti-PD-1 mAb plus lenvatinib had enhanced antitumor activity compared with anti-PD-1 mAb plus axitinib. Flow cytometry analysis showed that lenvatinib decreased the population of tumor-associated macrophages and increased that of IFNγ-positive CD8+ T cells. Activation of FGFR signaling inhibited the IFNγ-stimulated JAK/STAT signaling pathway and decreased expression of its target genes, including B2M, CXCL10, and PD-L1. Furthermore, inhibition of FGFR signaling by lenvatinib restored the tumor response to IFNγ stimulation in mouse and human RCC cell lines. These preclinical results reveal novel roles of tumor FGFR signaling in the regulation of cancer immunity through inhibition of the IFNγ pathway, and the inhibitory activity of lenvatinib against FGFRs likely contributes to the enhanced antitumor activity of combination treatment comprising lenvatinib plus anti-PD-1 mAb. SIGNIFICANCE: FGFR pathway activation inhibits IFNγ signaling in tumor cells, and FGFR inhibition with lenvatinib enhances antitumor immunity and the activity of anti-PD-1 antibodies.

Abstract
An 86-year-old woman in a wheelchair was accompanied by her husband and son as she visited our outpatient clinic due to disturbed consciousness and fever. Twenty-seven years earlier, she had been diagnosed with rheumatoid arthritis and had been treated with methotrexate (MTX) and low-dose prednisolone (PSL). She stopped taking MTX four years previously when she was diagnosed with diffuse large B cell lymphoma of the paranasal sinus. Her lymphoma went into remission after six cycles of systemic immunochemotherapy. MRI after hospitalization revealed a lesion in the splenium of the corpus callosum that was hyperintense on diffusion-weighted imaging and which had low apparent diffusion coefficient values. An analysis of the cerebrospinal fluid revealed no atypical cells. The MRI findings were atypical, but her consciousness disturbance improved, leading to the diagnosis of mild encephalitis/encephalopathy with a reversible splenial lesion, which would be associated with a transient consciousness disturbance with a good course. However, her consciousness worsened over the next 3 weeks. One month later, a contrast-enhanced MRI showed an enlarged lesion in the callosum as well as new lesions, and the diagnosis of secondary CNS lymphoma was made. Brain biopsy is often not feasible. Less invasive and highly accurate diagnostic methods are needed, such as the identification of a spinal fluid tumor marker.

Abstract
Lymphatic transport plays an important role in coordinating local immune responses. However, the biologic effects of impaired lymphatic flow in vivo are not fully understood. In this study, we investigated the roles of the lymphatic system in skin carcinogenesis and psoriasis-like inflammation using k-cyclin transgenic (kCYC+/-) mice, which demonstrate severe lymphatic dysfunction. kCYC+/- mice showed augmented tumor growth in the two-stage skin carcinogenesis model and severe clinical scores in imiquimod-induced psoriasis-like skin inflammation compared with wild-type mice. Although mRNA levels of inflammatory cytokines in skin after topical application of 12-O-tetradecanoylphorbol-13-acetate or imiquimod were comparable between kCYC+/- and wild-type mice, protein levels of inflammatory cytokines, such as IL-17A, IL-22, and IL-23, were significantly upregulated in kCYC+/- mice in both models. Consistently, signal transducer and activator of transcription 3 pathway and NF-κB signaling were augmented in epidermal keratinocytes in kCYC+/- mice. These results suggest that lymphatic dysfunction in kCYC+/- mice caused accumulation of inflammatory cytokines, leading to the exacerbation of two-stage skin carcinogenesis and imiquimod-induced psoriasis-like skin inflammation. These findings add insight into the clinical problems of secondary malignancies and inflammatory dermatoses that may occur with extremity lymphedema.

Background
Despite sufficient evidence on the importance of breast cancer screening, the screening rate has remained less than 50% in Japan. To promote behavioral change of individuals, it is important to reduce barriers to taking screening. The purpose of this study was to examine the effect of an environmental approach providing opportunities for mammography (MMG) in workplaces.
Methods
Female employees aged 40 years or older were eligible. Supermarket stores were randomly assigned into two groups, the intervention arm (leaflet and MMG) and the control arm (leaflet). From May to July 2018, participants in the intervention arm were given a leaflet informing the subsidies for breast cancer screening and were provided the opportunity to have MMG in their workplace. Participants in the control group were given the same leaflet, but they had to take the screening outside the workplace as usual. The primary outcome was the breast cancer screening rate in 2018, evaluated using self-administered questionnaires. The odds ratio (OR) and 95% confidence intervals (CIs) for the screening rate in the intervention arm compared with the control arm was estimated using multilevel logistic regression.
Results
We analyzed 1624 participants (mean age was 53 years) from 25 supermarket stores (intervention: 578 patients in 8 stores, control: 1046 patients in 17 stores). The screening rate in the intervention arm was 312 (54%) and was 125 (12%) in the control arm. The OR (and 95% CIs) was 7.81 (5.03-12.12) in the final model adjusted store level effects (i.e., stores and screening rate in 2017 at each store) and individual age and current smoking.
Conclusions
In a worksite-based cluster-randomized controlled trial conducted in a Japanese population, an environmental approach providing MMG opportunities in workplaces significantly increased the self-reported breast cancer screening rate within one year. (UMIN000030465)
Key messages
Providing the opportunity of mammography in Japanese supermarket stores improved the breast cancer screening rate. An environmental approach reducing barriers to screening may be more effective than conventional approaches in improving breast cancer screening rate.

Abstract
Abstract
Background
The clinical benefits of neurohormonal antagonist in patients with heart failure (HF) with mid-range and preserved ejection fraction (HFmrEF and HFpEF) were uncertain. This study aimed to evaluate the prognostic effect of starting angiotensin-converting enzyme inhibitors (ACE-I) / angiotensin II receptor blockers (ARB) and β-blocker during HF hospitalization in these patients.
Methods
We analyzed 858 consecutive patients with HFmrEF (EF:40–49%) or HFpEF (EF≥50%), who were hospitalized for acute decompensated HF, were discharged alive, and were not taking ACE-I/ARB or β-blockers at admission. The study population was classified into four groups according to the status of prescription of ACE-I/ARB and β-blocker at discharge: no neurohormonal antagonist (N=342, 39.9%), ACE-I/ARB only (N=128, 14.9%), β-blocker only (N=189, 22.0%), and both ACE-I/ARB and β-blocker (N=199, 23.2%) groups. The primary outcome measure was a composite of all-cause death or HF hospitalization.
Results
The cumulative 1-year incidence of the primary outcome measure was 41.2% in the no neurohormonal antagonist group, 34.0% in the ACE-I/ARB only group, 28.6% in the β-blocker only group, and 16.4% in the both ACE-I/ARB and β-blocker group (P<0.001). Compared with the no neurohormonal antagonist group, the both ACE-I/ARB and β-blocker group were associated with a significantly lower risk for a composite of all-cause death or HF hospitalization (HR: 0.59, 95% CI: 0.38–0.91, P=0.02).
Conclusions
In hospitalized patients with HFmrEF and HFpEF, starting both ACE-I/ARB and β-blocker was associated with a reduced risk of a composite of all-cause death or HF hospitalization compared with not starting ACE-I/ARB or β-blocker.

Abstract
Abstract
Background
Since atrial functional tricuspid regurgitation (AF-TR) is associated with increased heart failure and mortality, the management of AF-TR is clinically important. Atrial fibrillation (AF) plays the main role in AF-TR. However, the effectiveness of catheter ablation (CA) and mechanism of improvement of AF-TR haven't been fully evaluated.
Purpose
We sought to investigate the impact of CA for AF on AF-TR in patients with moderate or more TR.
Methods
We retrospectively investigated consecutive 2685 patients with AF who received CA from February 2004 to December 2019 in Japan. The current study population consisted of 102 patients with moderate or greater TR who underwent CA for AF. The echocardiographic parameters were compared between pre-ablation and post-ablation transthoracic echocardiography (TTE), and the recurrence rate of AF/ atrial tachycardia (AT) was measured.
Results
The mean age was 73.2 years, 53% were women. TR severity and TR jet area significantly improved after CA for AF (TR jet area: 5.8 [3.9–7.6] cm2 to 2.0 [1.1–3.0] cm2, p<0.001). In addition, mitral regurgitation (MR) jet area, left atrial (LA) area, mitral valve diameter, right ventricular (RV) end-diastolic area, right atrial (RA) area, tricuspid valve (TV) diameter decreased after CA (p<0.001, <0.001, <0.001, = 0.02, <0.001, and <0.001, respectively). There was no significant difference between one-year recurrence of AF/AT and TR severity at pre-ablation TTE (moderate 28.6%, moderate to severe 37.2%, and severe 31.6%, p=0.72).
Conclusions
TR severity and jet area improved after CA in patients with AF and moderate or more TR. RV size, RA size, TV diameter also decreased after CA, which may be associated with TR improvement. There was no significant difference between one-year recurrence of AF/AT and TR severity at pre-ablation TTE.

Abstract
Abstract
Background
Radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) is becoming a routine procedure to treat patients with drug-refractory symptomatic AF. However, data regarding very long-term clinical outcomes is limited. The aim of the present study was to evaluate the 10-year clinical outcomes of patients who underwent RFCA for paroxysmal and persistent AF.
Methods
We retrospectively enrolled 503 consecutive patients (mean age 66,9±9,51 years; 71,6% male) who underwent RFCA for drug-refractory symptomatic AF between February 2004 and June 2011. Follow-up information was obtained using medical records and/or telephonic interviews with the patient, relatives and/or referring physicians.
Results
Among 503 patients enrolled in this study, 362 had paroxysmal atrial fibrillation (PAF) and 141 had persistent atrial fibrillation (PeAF) (72% and 28%, respectively). Mean follow-up was 8,84±3,05 years. The 10-year event-free rate for recurrent atrial tachyarrhythmia (AT) after the first procedure was 44,5% (49,4% for PAF vs 31,9% for PeAF; p=0,002 by log-rank test) and 81,9% after the last procedure (87,3% for PAF and 67,9% for PeAF; p≤0,001 by log-rank test). AT recurrence was observed most commonly during the first 12 months of the initial procedure (56%), with only 18% of them occurring after 60 months. Multivariate analysis revealed that persistent AF (hazard ratio=1,366; 95% confidence interval 1,058–1,76; p=0,017) and duration of AF >5 years (hazard ratio=1,357; 95% confidence interval 1,064–1,732; p=0,005) were independent risk factors for AT recurrence. Regarding adverse events, there were 24 (4,8%) hospitalizations for acute decompensated heart failure, 20 (4%) ischemic strokes and 14 (2,8%) bleeding complications requiring hospital admissions. Patients taking oral anticoagulation and antiarrhythmic drugs at the end of the study accounted for 32,8% and 16,7% respectively.
Conclusions
RFCA for AF provided favorable results in terms of arrhythmia event-free survival in long-term follow-up with better results in patients with paroxysmal AF. Persistent AF and long-standing AF (beyond 5 years) were associated with AT recurrence. Despite the large number of patients who discontinued oral anticoagulation, thromboembolic adverse events were rare.

Abstract
Abstract
Background
Lymphocyte, total cholesterol, and albumin levels consist of Controlling Nutritional Status (CONUT) score, which has been reported to prognosticate patients with acute heart failure (AHF). However, the influence of each component of CONUT score on outcomes in patients with AHF was not fully elucidated.
Purpose
We aimed to evaluate the prognostic implication of the decrease in lymphocyte, total cholesterol, and albumin levels in patients with AHF.
Methods
We analyzed 1812 AHF patients in whom data at discharge were available from a multicenter registry. The decrease of lymphocyte (Ly) count was assigned with Ly≥1600/mL (31.0%), 1200≤ Ly <1600 (26.9%), 800≤ Ly <1200 (28.6%), Ly <800 (13.5% of patients). The decrease of total cholesterol (TC) was assigned with TC≥180mg/dL (28.9%), 140≤ TC <180 (42.2%), 100≤ TC <140 (26.7%), TC <100 (2.1% of patients). The decrease of albumin (Alb) was assigned and doubled with Alb≥3.5g/dL (45.7%), 3≤ Alb <3.5 (35.1%), 2.5≤ Alb <3 (15.2%), Alb <2.5 (3.9% of patients). The primary outcome measure was all-cause death after discharge from the index hospitalization. Cumulative incidences were estimated by the Kaplan-Meier method and differences were assessed with the log-rank test. We constructed multivariable Cox proportional hazard models to estimate the risk of the decrease in each value per grade, with the results expressed as the hazard ratios (HRs) and 95% confidence intervals (CIs).
Results
Cumulative one-year incidence of the all-cause death was higher with decreasing Ly, TC, and Alb levels (P<0.0001, P<0.0001, and P=0.02, respectively) (Figure 1). The adjusted hazard ratio for all-case death per grade decrease is most prominent in albumin (HR: 1.36, 95% CI: 1.20–1.54), followed by lymphocyte count (HR: 1,23, 95% CI: 1.10–1.38), whereas it became insignificant in total cholesterol (HR: 1.05, 95% CI: 0.91–1.21).
Conclusions
The prognostic implications after discharge were different in albumin, lymphocyte count, and total cholesterol in patients with AHF.

Abstract
Abstract
Background/Introduction
Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT), is a major health problem in the world. Several studies reported that autoimmune disorder is one of important risk factors for development of VTE. Furthermore, autoimmune disorder is thought to be a relatively strong risk factor for VTE recurrence, and extended anticoagulation therapy are recommended for prevention of VTE recurrence in patients with autoimmune disorders. However, it remains controversial whether patients with autoimmune disorders have higher risk for clinical events after VTE than those without.
Purpose
We sought to evaluate the clinical characteristics, management strategies, and long-term outcomes of patients with autoimmune disorders after excluding patients with active cancer in a large observational database in Japan.
Methods
The COMMAND VTE Registry is a multicenter registry enrolling 3027 consecutive patients with acute symptomatic VTE. After excluding patients with active cancer, the current study population consisted of 2332 patients, who were divided into 2 groups: patients with autoimmune disorders and those without. We estimated the cumulative incidences of the clinical outcomes. To adjust for the clinically relevant confounders, we used the multivariable Cox proportional hazard model to estimate the hazard ratio (HR) and their 95% confidence interval (CI) for the risk of patients with autoimmune disorders relative to those without for the clinical outcome measures. Furthermore, we added corticosteroids use at discharge to explore the effect of corticosteroids use.
Results
There were 188 patients (8.1%) with autoimmune disorders and 2144 patients (92%) without autoimmune disorders. Patients with autoimmune disorders were more often women (74%), and more often received corticosteroids at discharge (69%). The discontinuation rate of anticoagulation therapy was not significantly different between patients with autoimmune disorders and those without (38.0% vs. 39.7% at 3-year, P=0.35). The cumulative 5-year incidences of recurrent VTE and major bleeding were significantly higher in patients with autoimmune disorders than in those without (recurrent VTE: 14.3% vs. 8.3%, P=0.01; major bleeding: 14.9% vs. 8.8%, P=0.02). Even after adjusting confounders of patient characteristic, the excess risk of patients with autoimmune disorders relative to those without remained significant for recurrent VTE (HR 1.81, 95% CI 1.08–2.88, P=0.03) and major bleeding (HR 1.70, 95% CI 1.05–2.63, P=0.03). However, after adjusting for corticosteroids use at discharge, the excess risk was no longer significant for recurrent VTE (HR 1.42, 95% CI 0.75–2.61, P=0.27) nor major bleeding (HR 1.53, 95% CI 0.84–2.69, P=0.16).
Conclusions
Patients with autoimmune disorders had a higher risk for recurrent VTE and major bleeding than those without, and the excess risk could at least partly be attributable to corticosteroids use.

Abstract
Abstract
Background
The SYNTAX score II 2020 (SSII-2020), which was derived and externally validated from randomized trials, was designed to predict death following percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in patients with three-vessel disease and/or left main disease. We aimed to investigate its value in identifying the safest modality of revascularization in a non-randomized setting.
Methods
Five-year mortality was assessed in 7362 patients with three-vessel disease and/or left main disease enrolled in a Japanese PCI/CABG registry. New-generation drug eluting stents and imaging guidance became the default PCI strategy during enrolment of the last cohort. The discriminative ability of the SSII-2020 for 5-year mortality was assessed using Harrell's C statistic (C-index). Agreement between observed and predicted rates of all-cause mortality following either PCI or CABG and treatment benefit (absolute risk difference) for this outcome were assessed by calibration plots.
Results
The SSII-2020 had helpful discrimination (C-index = 0.72) and good calibration (intercept = −0.11, slope = 0.92) for 5-year mortality. The absolute risk difference in mortality between CABG and PCI (treatment benefit) was well calibrated when the whole population was grouped into quarters according to the predicted absolute risk difference of 5-year mortality. The observed differences in survival in favor of CABG were 4.2% (0.1 to 8.2%, log-rank p=0.05) and 8.5% (3.8 to 13.2%, log-rank p<0.01) in the respective third and fourth quarters. In contrast, the observed differences in survival were not significantly different in either the first (3.0% [−0.8 to 6.8%, log-rank p=0.12]) or the second quarter (1.3% [−2.4 to 5.1%, log-rank p=0.39]).
Conclusions
The SSII-2020 is well able to predict death at 5 years – and the mortality difference between PCI and CABG, and therefore has the potential to support decision making on revascularization in patients with three-vessel disease and/or left main coronary artery disease.

Abstract
Abstract
Background/Introduction
Patients with venous thromboembolism (VTE), including pulmonary embolism (PE), have a long-term risk of recurrence, and anticoagulation therapy is recommended for the prevention of recurrence. The latest 2019 European Society of Cardiology (ESC) guideline classified the risks of recurrence into low- (<3%/year), intermediate- (3–8%/year), and high- (>8%/year) risk, and recommended the extended anticoagulation therapy of indefinite duration for high-risk patients as well as intermediate-risk patients. However, extended anticoagulation therapy of indefinite duration for all of intermediate-risk patients have been a matter of active debate. Thus, additional risk assessment of recurrence in intermediate-risk patients might be clinically relevant in defining the optimal duration of anticoagulation therapy. Furthermore, bleeding risk during anticoagulation therapy should also be taken into consideration for optimal duration of anticoagulation therapy. However, there are limited data assessing the risk of recurrence as well as bleeding in patients with intermediate-risk for recurrence based on the classification in the latest 2019 ESC guideline.
Purpose
The current study aimed to identify the risk factors of recurrence as well as major bleeding in patients with intermediate-risk for recurrence, using a large observational database of VTE patients in Japan.
Methods
The COMMAND VTE Registry is a multicenter registry enrolling consecutive 3027 patients with acute symptomatic VTE among 29 centers in Japan. The current study population consisted of 1703 patients with intermediate-risk for recurrence. The primary outcome measure was recurrent VTE during the entire follow-up period, and the secondary outcome measures were recurrent VTE and major bleeding during anticoagulation therapy.
Results
In the multivariable Cox regression model for recurrent VTE incorporating the status of anticoagulation therapy as a time-updated covariate, off-anticoagulation therapy was strongly associated with an increased risk for recurrent VTE (HR 9.42, 95% CI 5.97–14.86). During anticoagulation therapy, the independent risk factor for recurrent VTE was thrombophilia (HR 3.58, 95% CI 1.56–7.50), while the independent risk factors for major bleeding were age ≥75 years (HR 2.04, 95% CI 1.36–3.07), men (HR 1.52, 95% CI 1.02–2.27), history of major bleeding (HR 3.48, 95% CI 1.82–6.14) and thrombocytopenia (HR 3.73, 95% CI 2.04–6.37).
Conclusions
Among VTE patients with intermediate-risk for recurrence, discontinuation of anticoagulation therapy was a very strong independent risk factor of recurrence during the entire follow-up period. The independent risk factors of recurrent VTE and those of major bleeding during anticoagulation therapy were different: thrombophilia for recurrent VTE, and advanced age, men, history of major bleeding, and thrombocytopenia for major bleeding.

Abstract
Abstract
Background/Introduction
Cancer is a strong risk factor for the development of venous thromboembolism (VTE) including pulmonary embolism (PE) and deep vein thrombosis (DVT). Patients with VTE have a long-term risk of recurrence, which can be prevented by anticoagulation therapy. Prolonged anticoagulation therapy is recommended for patients with cancer-associated VTE, although the risk of recurrence might depend on the individual patient.
Purpose
We aimed to identify the risk factors of recurrence in patients with cancer-associated VTE.
Methods
The COMMAND VTE Registry is a multicenter retrospective registry enrolling 3027 consecutive patients with acute symptomatic VTE among 29 Japanese centers between January 2010 and August 2014. The present study population consisted of 695 cancer-associated VTE patients. The primary outcome measure in the present study was recurrent VTE, which was defined as PE and/or DVT with symptoms accompanied by confirmation of a new thrombus or exacerbation of the thrombus by objective imaging examinations or autopsy. Discontinuation of anticoagulation was defined as a withdrawal of anticoagulation therapy lasting >14 days for any reason. We selected clinically relevant variables and variables with P values <0.1 in a univariate analysis as potential risk factors, and constructed a multivariable Cox proportional hazard model for recurrent VTE incorporating the anticoagulation therapy status as a time-updated covariate.
Results
Among the 695 study patients, recurrent VTE occurred in 78 patients, of whom 54 (69%) occurred within 6 months. The cumulative incidence of recurrent VTE was 7.7% at 3-months, 8.9% at 6-months, 11.8% at 1-year, and 17.7% at 5-years. The cumulative incidence of discontinuation of anticoagulation therapy was 18.0% at 3-months, 29.5% at 6-months, 43.4% at 1-year, and 66.5% at 5-years. The cumulative 5-year incidence of recurrent VTE was most frequent in patients with uterus/ovary cancer (26.0%), followed by those with lung cancer (24.7%). The multivariable Cox proportional hazard model revealed that chronic kidney disease (HR, 2.27; 95% CI, 1.36–3.77, P=0.002), a high D-dimer level at the time of VTE diagnosis (HR, 2.85; 95% CI, 1.71–4.74, P<0.001), advanced cancer (HR, 1.69; 95% CI, 1.05–2.72, P=0.03) and discontinuation of anticoagulation therapy (HR, 2.66; 95% CI, 1.53–4.63, P<0.001) were independently associated with an increased risk of recurrent VTE. No cancer site was independently associated with an increased risk for recurrent VTE when adjusting for the above mentioned risk factors in the multivariable Cox proportional hazard model, although the risk of recurrent VTE numerically differed according to the cancer site.
Conclusions
Among patients with cancer-associated VTE, chronic kidney disease, a high D-dimer level at the time of VTE diagnosis, advanced cancer, and discontinuation of anticoagulation therapy were independent risk factors of recurrence.

Abstract
Background The advantage of up‐front neck dissection (UFND) followed by chemoradiotherapy (CRT) for hypopharyngeal cancer (HPC) with advanced neck involvement remains controversial. We aimed to determine the indications. Methods The data of 41 and 14 patients with stage IVA/B (T1–T3 and ≥N2a) HPC who underwent UFND followed by CRT and received CRT, respectively, were retrospectively analyzed and compared. Results The 5‐year overall survival (OS) and disease‐specific survival rates for the UFND and CRT groups were 61% and 52% (p = 0.1019), and 89% and 74% (p = 0.2333), respectively. Moreover, patients aged ≥70 years or those with a pulmonary disease history had a significantly poorer prognosis due to aspiration pneumonia in the UFND group. The 5‐year regional control (RC) for the UFND and CRT groups were 92% and 57%, respectively (p = 0.0001). Conclusions UFND followed by CRT was feasible with satisfactory RC. To further improve OS, aspiration pneumonia prevention is essential.

Abstract
BACKGROUND Robot-assisted laparoscopic surgery has several advantages over conventional laparoscopy. However, population-based comparative studies for low anterior resection are limited. This article aimed to compare peri-operative results of robot-assisted low anterior resection (RALAR) and laparoscopy. METHODS This retrospective cohort study used data from patients treated with RALAR or conventional laparoscopic low anterior resection (CLLAR) between October 2018 and December 2019, as recorded in the Japanese National Clinical Database, a data set registering clinical information, perioperative outcomes, and mortality. Of note, the registry does not include information on the tumour location (centimetres from the anal verge) and diverting stoma creation. Perioperative outcomes, including rate of conversion to open surgery, were compared between RALAR and CLLAR groups. Confounding factors were adjusted for using propensity score matching. RESULTS Of 21 415 patients treated during the study interval, 20 220 were reviewed. Two homogeneous groups of 2843 patients were created by propensity score matching. The conversion rate to open surgery was significantly lower in the RALAR group than in the CLLAR group (0.7 versus 2.0 per cent; P < 0.001). The RALAR group had a longer operating time (median: 352 versus 283 min; P < 0.001), less intraoperative blood loss (15 versus 20 ml; P < 0.001), a lower in-hospital mortality rate (0.1 versus 0.5 per cent; P = 0.007), and a shorter postoperative hospital stay (median: 13 versus 14 days; P < 0.001) compared with the CLLAR group. The CLLAR group had a lower rate of readmission within 30 days (2.4 versus 3.3 per cent; P = 0.045). CONCLUSION These data highlight the reduced conversion rate, in-hospital mortality rate, intraoperative blood loss, and length of postoperative hospital stay for rectal cancer surgery in patients treated using robot-assisted laparoscopic surgery compared with laparoscopic low anterior resection.

Abstract
Background In the resting conditions, narrowing the window of coronary pressure measurements from the whole cardiac cycle to diastole improves diagnostic performance of coronary pressure–derived physiological index. However, whether this also applies to the hyperemic conditions has not yet been thoroughly evaluated. Objectives The purpose of this study was to assess whether diastolic fractional flow reserve (diastolic FFR) has better diagnostic performance in identifying ischemia-causing coronary lesions than conventional FFR in a prospective, multicenter, and independent core laboratory–based environment. Methods In this prospective multicenter registry at 29 Japanese centers, we compared the diagnostic performance of FFR, diastolic FFR, resting distal to aortic coronary pressure (Pd/Pa), and diastolic pressure ratio (dPR) using myocardial perfusion scintigraphy (MPS) as the reference standard in 378 patients with single-vessel coronary disease. Results Inducible myocardial ischemia was found on MPS in the relevant myocardial territory of the target vessel in 85 patients (22%). In the receiver-operating curve analyses, diastolic FFR had comparable area under the curve (AUC) compared with FFR (AUCdiastolic FFR: 0.66; 95% confidence interval [CI]: 0.58-0.73, vs AUCFFR: 0.66; 95% CI: 0.58-0.74, P = 0.624). FFR and diastolic FFR showed significantly larger AUCs than resting Pd/Pa (0.62; 95% CI: 0.54-0.70; P = 0.033 and P = 0.046) but did not show significantly larger AUCs than dPR (0.62; 95% CI: 0.55-0.70; P = 0.102 and P = 0.113). Conclusions Diastolic FFR showed a similar diagnostic performance to FFR as compared with MPS. This result reaffirms the use of FFR as the most accurate invasive physiological lesion assessment.

Abstract
Abstract
Background: Aberrant activation of Wnt/β-catenin signaling plays an important role in both carcinogenesis and modulation of the tumor microenvironment. E7386, an investigational anti-cancer agent, inhibits the binding of β-catenin to its transcriptional co-activator, CREB binding protein (CBP), thereby modulating Wnt/β-catenin signaling. We previously reported that E7386 suppressed tumor growth in preclinical mouse models with aberrant activation of Wnt/β-catenin signaling. Moreover, the combination of E7386 plus lenvatinib, a multiple receptor tyrosine kinase inhibitor that mainly targets vascular endothelial growth factor receptors and fibroblast growth factor receptors, showed stronger antitumor and antiangiogenic activities than each treatment alone. Here, we investigated the molecular mechanism of the combination activities of E7386 plus lenvatinib.
Methods: We examined antitumor activity of E7386 plus lenvatinib in multiple human tumor xenograft and mouse syngeneic models. Tumor samples underwent RNA sequencing (RNA-seq) followed by weighted gene correlation network analysis. Furthermore quantitative PCR was used to assess changes in the expression of some hypoxia-related genes. The protein interaction between β-catenin and HIF1 was analyzed by immunoprecipitation-western blotting.
Results: RNA-seq analysis of the effects of E7386, lenvatinib, and E7386 plus lenvatinib on the tumor microenvironment in the Hepa1-6 hepatocellular carcinoma syngeneic tumor model in mice showed that lenvatinib suppressed the expression of angiogenesis-related genes and that E7386 plus lenvatinib enhanced this suppression. Although lenvatinib increased the expression of hypoxia-related genes, E7386 plus lenvatinib attenuated this phenomenon. According to these results, we hypothesized that E7386 inhibits the formation of the β-catenin/HIF-1 complex. To confirm the effect of E7386 on the hypoxic response, we conducted an in vitro quantitative PCR assay under hypoxic conditions in Hepa1-6 cells and the human hepatocellular carcinoma cell lines, HepG2 and Hep3B. In accordance with the RNA-seq result, E7386 significantly suppressed the expression levels of hypoxia-related genes in the HepG2 and Hep3B cells. Finally, data from immunoprecipitation-western blotting demonstrated that β-catenin formed a complex with HIF-1 and that E7386 clearly inhibited this complex formation in HepG2 cells.
Conclusion: These results suggest that E7386 enhances angiogenesis inhibition when used in combination with lenvatinib and that E7386 suppresses the hypoxic response induced by angiogenesis inhibition. Further analysis is required to clarify the precise mechanisms of actions of the combination of E7386 plus lenvatinib.
