Abstract
BACKGROUND Multiple system atrophy (MSA) is a progressive, incurable, life-threatening neurodegenerative disease uniquely characterized by the risk of sudden death, which makes diagnosis delivery challenging for neurologists. Empirical studies on breaking a diagnosis of MSA are scarce, with no guidelines currently established. This study aimed to investigate neurologists' current practices and experiences in delivering the diagnosis of MSA. METHODS We conducted a multicenter online survey and employed a mixed-methods (quantitative and qualitative) study design in which responses to open-ended questions were analyzed qualitatively using critical incident technique. RESULTS Among the 194 neurologists surveyed, 166 opened the survey (response rate = 85.6%), of whom 144 respondents across various Japanese regions completed the survey. Accordingly, 92.3% and 82.8% of the participating neurologists perceived delivering the diagnosis of MSA and explaining the risk of sudden death as difficult, respectively. Factors independently associated with difficulties in diagnosis delivery included explaining the importance of the family decision making process in life-prolonging treatment, perceived difficulties in delivering information regarding the risk of sudden death, and perceived difficulties in differential diagnosis of MSA. CONCLUSIONS Our findings showed that the majority of neurologists perceived delivering the diagnosis of MSA and explaining the risk of sudden death as difficult, which could have been associated with the difficulty of breaking the diagnosis of MSA. Difficulty in conveying bad news in MSA are caused by various factors, such as empathic burden on neurologists caused by the progressive and incurable nature of MSA, the need to explain complex and important details, including the importance of the family decision-making process in life-prolonging treatment, difficulty of MSA diagnosis, and communication barriers posed by mental status and cognitive impairment in patients or their family members. Neurologists consider various factors in explaining the risk of sudden death (e.g., patient's personality, mental state, and degree of acceptance and understanding) and adjust their manner of communication, such as limiting their communication on such matters or avoiding the use of the term "sudden death" in the early stages of the disease. Although neurologists endeavor to meet the basic standards of good practice, there is room for the multiple aspects for improvement.

Abstract
BACKGROUND AND PURPOSE The aim of this study was to determine the prevalence of anti-myelin-associated glycoprotein (MAG) neuropathy and the current status of such patients in Japan. METHODS We conducted a nationwide survey in 2021 using established epidemiological methods. Questionnaires were sent to all neurology and pediatric neurology departments throughout Japan to identify patients with anti-MAG neuropathy. An initial questionnaire was used to determine the number of patients, with a second one used to collect detailed clinical information. RESULTS The estimated number of patients with anti-MAG neuropathy was 353, with a prevalence of 0.28 per 100,000 and an incidence of 0.05 per 100,000. The detailed clinical profiles of 133 patients were available. The median (range) age of onset was 67 (30-87) years, with a prominent peak in the age range 66-70 years, and the male-to-female ratio was 3.6. Most patients had distal sensory-predominant polyneuropathy, and neuropathic pain (50%), or sensory ataxia (42%), while 18% had Waldenström's macroglobulinemia or multiple myeloma. Intravenous immunoglobulin was the most frequently used treatment (65%), but the response rate was <50%, whereas rituximab was given in 32% of patients, and 64% of these showed improvement. At the last visit, 27% of patients could not walk independently. CONCLUSIONS This study on anti-MAG neuropathy provides updated insights into the epidemiology of this disease, clinical profiles, and treatment approaches in Japan. Rituximab therapy, used for only one-third of the patients, demonstrated efficacy. During the final visit, a quarter of the patients were unable to walk independently. Further studies are warranted to determine the optimal management of this rare and intractable disorder.

Abstract
BACKGROUND The clinicopathological factors indicating risk of recurrence are used to guide the choice of perioperative therapy in patients with breast cancer. Although several risk factors for recurrence have been reported in patients with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) early breast cancer in Japan, there has been no systematic review quantifying potential risk factors. METHODS We performed a systematic literature review and meta-analysis using the MEDLINE, Embase, Cochrane CENTRAL, and Japan Medical Abstract Society databases to identify risk factors for recurrence in HR+/HER2- early breast cancer in Japan. The primary outcome was relapse-free or disease-free survival (RFS/DFS), and the secondary outcomes were overall survival and breast cancer-specific survival (BCSS). RESULTS Searches identified 42 eligible publications. Meta-analyses identified lymph node metastasis (hazard ratio: 2.76 [95% confidence interval: 1.97-3.88]), large tumor size (1.67 [1.24-2.23]), high histological grade (1.50 [1.04-2.16]), and high nuclear grade (2.02 [1.61-2.54]) as risk factors for RFS/DFS. Lymph node metastasis (2.43 [1.28-4.63]), large tumor size (1.80 [1.24-2.62]), and high histological grade (2.02 [1.44-2.84]) were also risk factors for overall survival, and high progesterone status was a possible favorable prognostic factor for BCSS (0.20 [0.10-0.42]). CONCLUSIONS Identified risk factors were consistent with the previous reports, and this study provides quantitative summary of risk factors for HR+/HER2- early breast cancer recurrence in Japan.

Abstract
Japan is lagging in cervical cancer prevention. The effectiveness of a self-sampling human papillomavirus (HPV) test, a possible measure to overcome this situation, has not yet been evaluated. A randomized controlled trial was performed to evaluate the effectiveness of a self-sampling HPV test on detection of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and screening uptake. Women between 30 and 58 years old who did not participate in the cervical cancer screening program for ≥3 years were eligible and assigned to the intervention group (cytology or self-sampling HPV test) or control group (cytology). Participants assigned to the intervention group were sent a self-sampling kit according to their ordering (opt-in strategy). A total of 7337 and 7772 women were assigned to the intervention and control groups, respectively. Screening uptake in the intervention group was significantly higher than that in the control group (20.0% vs. 6.4%; risk ratio: 3.10; 95% confidence interval [CI]: 2.82, 3.42). The compliance rate with cytology triage for HPV-positive women was 46.8% (95% CI: 35.5%, 58.4%). CIN2+ was detected in five and four participants in the intervention and control groups, respectively; there was no difference for intention-to-screen analysis (risk ratio: 1.32; 95% CI: 0.36, 4.93). Self-sampling of HPV test increased screening uptake; however, no difference was observed in the detection of CIN2+, probably due to the low compliance rate for cytology triage in HPV-positive women. Efforts to increase cytology triage are essential to maximize precancer detections.

Abstract
Understanding the factors that influence people's decisions regarding vaccination is essential to promote vaccination. We aimed to clarify the motivations for receiving booster vaccines. We conducted a paper-based questionnaire distributed during January-February 2022 involving students and faculty staff who received the first COVID-19 vaccination at the mass vaccination program during June-September 2021 at Keio University. A total of 1725 participants were enrolled, and all completed the survey. Among these, 64.9% reported a significant adverse event (AEs) affecting daily life after the second vaccine. "Fear of severe COVID-19 illness" (72.6%) was the most common reason for getting vaccinated, followed by "concern of infecting others" (68.4%) and "fear of COVID-19 infection itself" (68.3%). Television emerged as the most influential source of information (80%), followed by university information (50.2%) and social networking sites (42.8%). Multivariate analysis revealed "fear of severe COVID-19 illness", "fear of COVID-19 infection itself", and "trust in the efficacy and safety of the vaccines in general" were significantly correlated with willingness to receive paid vaccinations. The severity of AEs and source of information were not related to participants' willingness to receive booster vaccinations. Participants with positive reasons for vaccination were more likely to accept a third dose.

Abstract
AIM Live two-way video, easily accessible from home via smartphones and other devices, is becoming a new way of providing psychiatric treatment. However, lack of evidence for real-world clinical setting effectiveness hampers its approval by medical insurance in some countries. Here, we conducted the first large-scale pragmatic, randomized controlled trial to determine the effectiveness of long-term treatment for multiple psychiatric disorders via two-way video using smartphones and other devices, which are currently the primary means of telecommunication. METHODS This randomized controlled trial compared two-way video versus face-to-face treatment for depressive disorder, anxiety disorder, and obsessive-compulsive disorder in the subacute/maintenance phase during a 24-week period. Adult patients with the above-mentioned disorders were allocated to either a two-way video group (≥50% video sessions) or a face-to-face group (100% in-person sessions) and received standard treatment covered by public medical insurance. The primary outcome was the 36-Item Short-Form Health Survey Mental Component Summary (SF-36 MCS) score. Secondary outcomes included all-cause discontinuation, working alliance, adverse events, and the severity rating scales for each disorder. RESULTS A total of 199 patients participated in this study. After 24 weeks of treatment, two-way video treatment was found to be noninferior to face-to-face treatment regarding SF-36 MCS score (48.50 vs 46.68, respectively; p < 0.001). There were no significant differences between the groups regarding most secondary end points, including all-cause discontinuation, treatment efficacy, and satisfaction. CONCLUSION Two-way video treatment using smartphones and other devices, was noninferior to face-to-face treatment in real-world clinical settings. Modern telemedicine, easily accessible from home, can be used as a form of health care.

Abstract
BACKGROUND AND OBJECTIVES To investigate the current epidemiology, clinical profile, and treatment of chronic inflammatory demyelinating polyneuropathy (CIDP) using a nationwide survey in Japan. METHODS We conducted a nationwide survey using an epidemiologic method established in 2021. Questionnaire sheets were sent to the hospital departments of neurology and pediatric neurology throughout Japan. A primary questionnaire was used to determine the number of patients and their prevalence, and a second questionnaire was used to collect detailed clinical information. RESULTS The primary survey showed that the estimated number of patients with CIDP was 4,180, with a prevalence of 3.3 per 100,000 persons. In the secondary survey, detailed clinical data were available for 1,257 patients. The male-to-female ratio was 1.5:1, and the median age at onset was 52 years. Typical CIDP was the most frequent subtype (52%), followed by distal (17%) and multifocal/focal CIDP (17%). Initial treatments included immunoglobulin therapy (72%), corticosteroids (15%), and others (13%). Among patients with CIDP, 78% had a progressive/relapsing course, 14% did not respond to first-line treatments, and 18% could not walk independently at the last visit. Among the subtypes, typical CIDP had the most severe disability before treatment (44% of patients could not walk independently). However, they showed a more favorable response to treatment than those with distal or multifocal CIDP. In the subgroup analyses, logistic regression analyses showed that younger age at onset, no muscle atrophy, and abnormal median-normal sural sensory nerve responses were associated with a higher probability of independent walking. DISCUSSION Our study represents the largest cohort study on CIDP to demonstrate the current epidemiologic and clinical status of CIDP in Japan. Clinical subtypes seem to be associated with different treatment responses and outcomes; therefore, an appropriate treatment strategy according to the pathophysiology of each subtype is required to improve the prognosis of CIDP.

Abstract
BACKGROUND AND AIM Changes in the number of surgeries for gastric cancer during the coronavirus disease 2019 (COVID-19) pandemic have been reported, but data are insufficient to understand the impact at the national level. This study aimed to determine the impact of the COVID-19 pandemic on gastric surgery in Japan. METHODS Insurance claims data registered from January 2015 to January 2021 were used. Changes in the number of endoscopic resections and gastrectomies for gastric cancer were estimated using an interrupted time-series analysis. RESULTS The number of endoscopic resections significantly decreased in July 2020 (-1565; 95% confidence interval [CI]: -2022, -1108) and January 2021 (-539; 95% CI: -970, -109), and the number of laparoscopic surgeries significantly decreased in July 2020 (-795; 95% CI: -1097, -492), October 2020 (-313; 95% CI: -606, -19), and January 2021 (-507; 95% CI: -935, -78). Meanwhile, the number of open gastrectomies remained unchanged, and the number of robot-assisted gastrectomies steadily increased since their coverage by public health insurance in April 2018. CONCLUSIONS The decreased number of endoscopic resections and laparoscopic surgeries in Japan suggests a decline in early-stage gastric cancer diagnosis, likely due to the suspension of gastric cancer screening and diagnostic testing during the pandemic. Meanwhile, the number of open and robot-assisted gastrectomies remained unchanged and increased, respectively, indicating that these applications were not affected by the pandemic-related medical crisis. These findings highlight that procedures for cancer diagnosis, including screening, should still be provided during pandemics.

Abstract
BACKGROUND The coronavirus disease 2019 pandemic prompted healthcare providers to use different approaches from the current standards of care. We aimed to identify the changes in the number of treatments for primary non-small cell lung cancer (NSCLC) and metastatic lung cancer during the pandemic. METHODS We used nationwide insurance claims data from January 2015 to January 2021, and estimated changes in the number of treatments using an interrupted time series analysis. RESULTS The number of surgical resections for primary NSCLC significantly decreased in April 2020 (-888; 95% confidence interval [CI]: -1530 to -246) and July 2020 (-1314; 95% CI: -1935 to -694), while the number of stereotactic body radiotherapies (SBRTs) increased in April 2020 (95; 95% CI: 8-182) and July 2020 (111; 95% CI: 24-198). The total number of treatments for primary NSCLC remained unchanged; however, non-significant decreases were observed in 2020. The number of surgical resections for metastatic lung cancer significantly decreased in April 2020 (-201; 95% CI: -337 to -65), but it eventually increased in July 2020 (170; 95% CI: 32-308). Additionally, the number of SBRTs significantly increased in April 2020 (37; 95% CI: 3-71) and October 2020 (57; 95% CI: 23-91). The total number of treatments for metastatic lung cancer was maintained, with an initial decrease in April 2020 followed by a subsequent increase in July and October 2020. CONCLUSION In Japan, surgical triage for primary and metastatic lung cancer are likely to have been implemented during the pandemic. Despite these proactive measures, patients with primary NSCLC may have been untreated, likely owing to their undiagnosed disease, potentially leading to a deterioration in prognosis. By contrast, patients diagnosed with cancer prior to the pandemic are presumed to have received standard management throughout the course of the pandemic.

Abstract
BACKGROUND We have previously reported apolipoprotein A2-isoforms (apoA2-is) as candidate plasma biomarkers for early-stage pancreatic cancer. The aim of this study was the clinical development of apoA2-is. METHODS We established a new enzyme-linked immunosorbent sandwich assay for apoA2-is under the Japanese medical device Quality Management System requirements and performed in vitro diagnostic tests with prespecified end points using 2732 plasma samples. The clinical equivalence and significance of apoA2-is were compared with CA19-9. RESULTS The point estimate of the area under the curve to distinguish between pancreatic cancer (n = 106) and healthy controls (n = 106) was higher for apoA2-ATQ/AT [0.879, 95% confidence interval (CI): 0.832-0.925] than for CA19-9 (0.849, 95% CI 0.793-0.905) and achieved the primary end point. The cutoff apoA2-ATQ/AT of 59.5 μg/mL was defined based on a specificity of 95% in 2000 healthy samples, and the reliability of specificities was confirmed in two independent healthy cohorts as 95.3% (n = 106, 95% CI 89.4-98.0%) and 95.8% (n = 400, 95% CI 93.3-97.3%). The sensitivities of apoA2-ATQ/AT for detecting both stage I (47.4%) and I/II (50%) pancreatic cancers were higher than those of CA19-9 (36.8% and 46.7%, respectively). The combination of apoA2-ATQ/AT (cutoff, 59.5 μg/mL) and CA19-9 (37 U/mL) increased the sensitivity for pancreatic cancer to 87.7% compared with 69.8% for CA19-9 alone. The clinical performance of apoA2-is was blindly confirmed by the National Cancer Institute Early Detection Research Network. CONCLUSIONS The clinical performance of ApoA2-ATQ/AT as a blood biomarker is equivalent to or better than that of CA19-9.

Abstract
BACKGROUND The second demonstration experiment of supporting elderly people going out with the Choisoko system was conducted. The first study showed that for women, friends, shopping, convenience, and events are factors that have the potential to be effective motivational factors for encouraging these women to go out. On the other hand, these factors did not lead to any behavioral change in men. Since there are approximately 15 million men over the age of 65 in Japan, behavioral changes in the entire elderly population will not occur without guidance for elderly men to go out. METHODS Sixteen elderly men and forty-seven elderly women participated. Interestingly, men are far more passionate about games than women. Therefore, we hypothesized that a preference for games could be a hint as to how we might encourage older men to go out. Then, a second demonstration experiment was conducted, and we analyzed the relationship between six game preferences and the frequency of going out. RESULTS Among gaming preferences, men with gaming preferences such as Philanthropists, Achievers, and Free Spirits showed a tendency to go out. CONCLUSIONS These stimuli may have the potential to be factors that may encourage elderly men to go out.

Abstract
BACKGROUND Overall survival is considered as one of the most important endpoints of treatment efficacy but often requires long follow-up. This study aimed to determine the validity of recurrence-free survival as a surrogate endpoint for overall survival in patients with surgically resectable advanced oesophageal squamous cell carcinoma (OSCC). METHODS Patients with OSCC who received neoadjuvant cisplatin and 5-fluorouracil, or docetaxel, cisplatin and 5-fluorouracil, at 58 Japanese oesophageal centres certified by the Japan Esophageal Society were reviewed retrospectively. The correlation between recurrence-free and overall survival was assessed using Kendall's τ. RESULTS The study included 3154 patients. The 5-year overall and recurrence-free survival rates were 56.6 and 47.7% respectively. The primary analysis revealed a strong correlation between recurrence-free and overall survival (Kendall's τ 0.797, 95% c.i. 0.782 to 0.812) at the individual level. Subgroup analysis showed a positive relationship between a more favourable pathological response to neoadjuvant chemotherapy and a higher τ value. In the meta-regression model, the adjusted R2 value at the institutional level was 100 (95% c.i. 40.2 to 100)%. The surrogate threshold effect was 0.703. CONCLUSION There was a strong correlation between recurrence-free and overall survival in patients with surgically resectable OSCC who underwent neoadjuvant chemotherapy, and this was more pronounced in patients with a better response to neoadjuvant chemotherapy.

Abstract
Objective This study aimed to investigate the clinical features of long COVID cases presenting with upper respiratory symptoms, a topic not yet fully elucidated. Study Design Prospective cohort study. Setting A multicenter study involving 26 medical facilities in Japan. Methods Inclusion criteria were patients aged ≥18 years old with a confirmed COVID-19 diagnosis via severe acute respiratory syndrome coronavirus 2 polymerase chain reaction or antigen testing, who were hospitalized at the participating medical facilities. Analyzing clinical information and patient-reported outcomes from 1009 patients were analyzed. The outcome measured the degree of initial symptoms for taste or olfactory disorders and assessed the likelihood of these symptoms persisting as long COVID, as well as the impact on quality of life if the upper respiratory symptoms persisted as long COVID. Results Patients with high albumin, low C-reactive protein, and low lactate dehydrogenase in laboratory tests tended to experience taste or olfactory disorders as part of long COVID. Those with severe initial symptoms had a higher risk of experiencing residual symptoms at 3 months, with an odds ratio of 2.933 (95% confidence interval [CI], 1.282-6.526) for taste disorders and 3.534 (95% CI, 1.382-9.009) for olfactory disorders. Presence of upper respiratory symptoms consistently resulted in lower quality of life scores. Conclusion The findings from this cohort study suggest that severe taste or olfactory disorders as early COVID-19 symptoms correlate with an increased likelihood of persistent symptoms in those disorders as long COVID.

Abstract
A decreased body mass index (BMI) over time is associated with a poor prognosis for patients on hemodialysis. We aimed to examine whether this association also applies to patients with peritoneal dialysis (PD). BMI change was defined as the percentage change in the BMI between the time of PD catheter insertion and six months after its insertion. The association between the BMI change and all-cause mortality or PD discontinuation from six months after PD catheter insertion until October 2021 was investigated. This retrospective cohort study included 122 patients (aged 61.1 ± 12.1 years; 90 males) who underwent PD catheter insertion between January 2008 and March 2020. The median follow-up period was 43.1 (21.2-78.8) months. The median six-month percentage change in the BMI was -2.14 (-5.56-1.84)%, and patients were categorized into tertiles based on their BMI changes. The fully-adjusted Cox regression analysis revealed a significantly higher rate of PD discontinuation or all-cause mortality (hazard ratio (HR): 2.48; 95%; confidence interval (CI): 1.41-4.37) in patients with the lowest tertile (T1, BMI change: < -4.13%) compared to patients with the middle tertile (T2, BMI change: -4.13%-0.67%). The risk was not significantly higher in patients with the highest tertile (T3, BMI change: >0.67%) than those in the T2 group (HR: 1.18; 95% CI: 0.66-2.11). A decreased BMI over time is independently associated with HD transfer or all-cause mortality among patients initiating PD, which highlights the importance of the 6-month BMI change as a novel prognostic marker.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread rapidly since 2019, and the number of reports regarding long COVID has increased. Although the distribution of long COVID depends on patient characteristics, epidemiological data on Japanese patients are limited. Hence, this study aimed to investigate the distribution of long COVID in Japanese patients. This study is the first nationwide Japanese prospective cohort study on long COVID. METHODS This multicenter, prospective cohort study enrolled hospitalized COVID-19 patients aged ≥18 years at 26 Japanese medical institutions. In total, 1200 patients were enrolled. Clinical information and patient-reported outcomes were collected from medical records, paper questionnaires, and smartphone applications. RESULTS We collected data from 1066 cases with both medical records and patient-reported outcomes. The proportion of patients with at least one symptom decreased chronologically from 93.9% (947/1009) during hospitalization to 46.3% (433/935), 40.5% (350/865), and 33.0% (239/724) at 3, 6, and 12 months, respectively. Patients with at least one long COVID symptom showed lower quality of life and scored higher on assessments for depression, anxiety, and fear of COVID-19. Female sex, middle age (41-64 years), oxygen requirement, and critical condition during hospitalization were risk factors for long COVID. CONCLUSIONS This study elucidated the symptom distribution and risks of long COVID in the Japanese population. This study provides reference data for future studies of long COVID in Japan.

Abstract
PURPOSE Determination of optimal treatment strategies for HER2-positive advanced gastric cancer (AGC) in randomized trials is necessary despite difficulties in direct comparison between trastuzumab deruxtecan (T-DXd) and nivolumab as third or later-line treatments. MATERIALS AND METHODS This single-institution, retrospective study aimed to describe the real-world efficacy and safety of T-DXd and nivolumab as ≥ third line treatments for HER2-positive AGC between March 2016 and May 2022. Overall, 58 patients (median age, 64 years; 69% male) were eligible for the study (T-DXd group, n=20; nivolumab group, n=38). RESULTS Most patients exhibited a HER2 3+ status (72%) and presented metastatic disease at diagnosis (66%). The response rates of 41 patients with measurable lesions in the T-DXd and nivolumab groups were 50% and 15%, respectively. The T-DXd and nivolumab groups had a median progression-free survival of 4.8 months (95% confidence interval [CI], 3.3, 7.0) and 2.3 months (95% CI, 1.5, 3.5), median overall survival (OS) of 10.8 months (95% CI, 6.9, 23.8) and 11.7 months (95% CI, 7.6, 17.1), and grade 3 or greater adverse event rates of 50% and 2%, respectively. Overall, 64% patients received subsequent treatment. Among 23 patients who received both regimens, the T-DXd-nivolumab and nivolumab-T-DXd groups had a median OS of 14.0 months (95% CI, 5.0, not reached) and 19.3 months (95% CI, 9.5, 25.1), respectively. CONCLUSIONS T-DXd and nivolumab showed distinct efficacy and toxicity profiles as ≥ third line treatments for HER2-positive AGC. Considering the distinct features of each regimen, they may help clinicians personalize optimal treatment approaches for these patients.

Abstract
BACKGROUND This study aimed to elucidate the clinicopathological and molecular features of HER2-amplified and HER2-low colorectal cancers (CRCs). We also characterised HER2 expression statuses in CRCs focusing on their intratumoral heterogeneity and alterations in metastatic lesions to establish practical HER2 status assessment. METHODS We evaluated 1009 CRCs for HER2 expression and HER2 amplification by immunohistochemistry and FISH, respectively, and correlated the results to clinicopathological and molecular data. For HER2-positive tumours, HER2 expression in metastatic lesions was also assessed. RESULTS Twenty-five HER2-amplified (2.5%) and 46 HER2-low tumours (4.6%) were identified. HER2-amplified tumours consistently lacked a mucinous component and HER2-low tumours tended to be in the right colon, but no other clinicopathological features were noted. KRAS, NRAS or BRAF mutations were detected in only two HER2-amplified tumours (8%), whereas 23 HER2-low tumours (50%) had one of these mutations. Most HER2-amplified and HER2-low tumours showed a homogeneous or mosaic HER2 expression pattern and a clustered heterogeneous expression pattern was rather rare. HER2 expression was maintained in most metastatic lesions in both HER2-amplified (93%) and HER2-low tumours (81%). CONCLUSIONS These results suggest that biopsy-based assessment of primary lesions is appropriate for the identification of CRC patients eligible for systemic HER2-targeted therapy.

Abstract
BACKGROUND & AIMS This study examined the additional value of magnifying chromoendoscopy (MCE) on magnifying narrow-band imaging endoscopy (M-NBI) in the optical diagnosis of colorectal polyps. METHODS A multicenter prospective study was conducted at 9 facilities in Japan and Germany. Patients with colorectal polyps scheduled for resection were included. Optical diagnosis was performed by M-NBI first, followed by MCE. Both diagnoses were made in real time. MCE was performed on all type 2B lesions classified according to the Japan NBI Expert Team classification and other lesions at the discretion of endoscopists. The diagnostic accuracy and confidence of M-NBI and MCE for colorectal cancer (CRC) with deep invasion (≥T1b) were compared on the basis of histologic findings after resection. RESULTS In total, 1173 lesions were included between February 2018 and December 2020, with 654 (5 hyperplastic polyp/sessile serrated lesion, 162 low-grade dysplasia, 403 high-grade dysplasia, 97 T1 CRCs, and 32 ≥T2 CRCs) examined using MCE after M-NBI. In the diagnostic accuracy for predicting CRC with deep invasion, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for M-NBI were 63.1%, 94.2%, 61.6%, 94.5%, and 90.2%, respectively, and for MCE they were 77.4%, 93.2%, 62.5%, 96.5%, and 91.1%, respectively. The sensitivity was significantly higher in MCE (P < .001). However, these additional values were limited to lesions with low confidence in M-NBI or the ones diagnosed as ≥T1b CRC by M-NBI. CONCLUSIONS In this multicenter prospective study, we demonstrated the additional value of MCE on M-NBI. We suggest that additional MCE be recommended for lesions with low confidence or the ones diagnosed as ≥T1b CRC. Trials registry number: UMIN000031129.

Abstract
BACKGROUND Trifluridine/tipiracil (FTD/TPI) prolongs survival in the third- or later-line treatment for advanced gastric cancer (GC), esophagogastric junction (EGJ) adenocarcinoma, and colorectal cancer. While single-arm phase II trials showed promising outcomes of FTD/TPI plus ramucirumab (RAM) as third- or later-line treatments for advanced GC or EGJ cancer, there have been no clinical trials to directly compare FTD/TPI plus RAM with FTD/TPI monotherapy. Therefore, we have started a randomised phase II trial to evaluate the efficacy and safety of FTD/TPI plus RAM compared with FTD/TPI monotherapy as third- or later-line treatments in patients with advanced GC and EGJ adenocarcinoma. METHODS This RETREVE trial (WJOG15822G) is a prospective, open-label, randomised, multicentre phase II trial comparing FTD/TPI plus RAM versus FTD/TPI monotherapy in a third- or later-line setting. Eligibility criteria include age of > 20 years; performance status of 0 or 1; unresectable or recurrent gastric or EGJ adenocarcinoma; confirmed HER2 status; refractory or intolerant to fluoropyrimidine, taxane or irinotecan; refractory to RAM (not intolerant); and at least a measurable lesion per RECIST 1.1. FTD/TPI (35 mg/m2 twice daily, evening of day 1 to morning of day 6 and evening of day 8 to morning of day 13) was administered orally every 4 weeks, and RAM (8 mg/kg) was administered intravenously every 2 weeks. The primary endpoint is progression-free survival (PFS), and the secondary endpoints are overall survival, objective response rate, disease control rate, and safety. The expected hazard ratio of PFS is set as 0.7, assuming 4-month PFS rate of 27% in FTD/TPI monotherapy and 40% in FTD/TPI plus RAM. The number of subjects was 110, with a one-sided alpha error of 0.10 and power of 0.70. DISCUSSION This study will clarify the additional effect of RAM continuation beyond disease progression on FTD/TPI in the third- or later-line setting for patients with advanced GC or EGJ cancer.

Abstract
PURPOSE In terms of medical policy for cervical cancer prevention, Japan lags far behind other industrialized countries. We initiated a randomized controlled trial to evaluate the self-sampling human papillomavirus (HPV) test as a tool to raise screening uptake and detection of pre-cancer. This study was conducted to explore the acceptability and preference of self-sampling using a subset of the data from this trial. METHODS A pre-invitation letter was sent to eligible women, aged 30-59 years who had not undergone cervical cancer screening for three or more years. After excluding those who declined to participate in this trial, the remaining women were assigned to the self-sampling and control groups. A second invitation letter was sent to the former group, and those wanting to undergo the self-sampling test ordered the kit. A self-sampling HPV kit, consent form, and a self-administered questionnaire were sent to participants who ordered the test. RESULTS Of the 7,340 participants in the self-sampling group, 1,196 (16.3%) administered the test, and 1,192 (99.7%) answered the questionnaire. Acceptability of the test was favorable; 75.3-81.3% of participants agreed with positive impressions (easy, convenient, and clarity of instruction), and 65.1-77.8% disagreed with negative impressions (painful, uncomfortable, and embarrassing). However, only 21.2% were confident in their sampling procedure. Willingness to undergo screening with a self-collected sample was significantly higher than that with a doctor-collected sample (89.3% vs. 49.1%; p<0.001). Willingness to undergo screening with a doctor-collected sample was inversely associated with age and duration without screening (both p<0.001), but that with a self-collected sample was not associated. CONCLUSIONS Among women who used the self-sampling HPV test, high acceptability was confirmed, while concerns about self-sampling procedures remained. Screening with a self-collected sample was preferred over a doctor-collected sample and the former might alleviate disparities in screening rates.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic forced us to accept changes in our usual diagnostic procedures and treatments for colorectal cancer. This study aimed to determine the impact of the pandemic on colorectal cancer treatment in Japan. METHODS The number of colorectal surgeries, stoma constructions, stent placements or long tube insertions, and neoadjuvant chemoradiotherapies were determined each month using sampling datasets from the National Database of Health Insurance Claims and Specific Health Checkups of Japan. The observation periods before and during the pandemic were January 2015 to January 2020 and April 2020 to January 2021, respectively. An interrupted time-series analysis was used to estimate the changes in the number of procedures during the pandemic. RESULTS The number of endoscopic surgeries for colon cancer significantly decreased in April and July 2020 and for rectal cancer in April 2020. Additionally, the number of laparoscopic and open surgeries for colon cancer significantly decreased in July 2020 and October 2020, respectively. The number of stoma constructions and stent placements or long tube insertions did not increase during the observation period. Neoadjuvant chemoradiotherapy for rectal cancer significantly increased in April 2020 but levels returned shortly thereafter. These results suggest that the recommendations to overcome the pandemic proposed by expert committees, including the replacement of laparoscopic surgery with open surgery, stoma construction to avoid anastomotic leak, and replacement of surgery on the ileus with stent placement, were not widely implemented in Japan. However, as an exception, neoadjuvant chemoradiotherapy for rectal cancer was performed as an alternative treatment to delay surgery in small quantities. CONCLUSION A declining number of surgeries raises concerns about cancer stage progression; however, we found no evidence to suggest cancer progression from the trajectory of the number of stoma constructions and stent placements. In Japan, even during the pandemic, conventional treatments were performed.

Abstract
Various countries have reported a decrease in breast cancer surgeries during the coronavirus disease 2019 (COVID-19) pandemic; however, inconsistent results have been reported in Japan. This study revealed changes in the number of surgeries during the pandemic using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) from January 2015 to January 2021, where insurance claims data from Japan as a whole are comprehensively accumulated. The number of breast-conserving surgeries (BCS) without axillary lymph node dissection (ALND) significantly decreased in July (- 846; 95% confidence interval (CI) - 1190 to - 502) and October 2020 (- 540; 95% CI - 861 to - 218). No decrease was observed for other types of surgery, BCS with ALND, and mastectomy with or without ALND. In the age-specific subgroup analysis, significant and transient reduction in BCS without ALND was observed in all age groups (0-49, 50-69, and ≥ 70 years). The number of BCS without ALND significantly decreased for a relatively short period in the early pandemic stages, suggesting reduced surgery for patients with a relatively low stage of cancer. Some patients with breast cancer might have been left untreated during the pandemic, and an unfavorable prognosis would be a concern.

Abstract
BACKGROUND To our knowledge, no nationwide epidemiological study of myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) has been conducted. OBJECTIVE We examined the epidemiology and clinical features of MOGAD in Japan. METHODS We distributed questionnaires on the clinical characteristics of patients with MOGAD to neurology, pediatric-neurology, and neuro-ophthalmology facilities throughout Japan. RESULTS In total, 887 patients were identified. The estimated number of total and newly diagnosed MOGAD patients was 1,695 [95% confidence interval (CI): 1483-1907] and 487 (95% CI: 414-560), respectively. The estimated prevalence and incidence were 1.34/100,000 (95% CI: 1.18-1.51) and 0.39/100,000 (95% CI: 0.32-0.44), respectively. The median age at onset was 28 years (range: 0-84 years). At onset, optic neuritis was present in approximately 40% of patients, irrespective of the onset age. Acute disseminated encephalomyelitis was more frequent in younger patients, whereas brainstem encephalitis, encephalitis, and myelitis were more frequent in elderly patients. Immunotherapy was highly effective. CONCLUSION The prevalence and incidence rates of MOGAD in Japan are similar to those in other countries. Notable characteristics such as the preferential occurrence of acute disseminated encephalomyelitis in children exist; however, general characteristics including symptoms and treatment response are common irrespective of the onset age.

Abstract
BACKGROUND The 6-min walk test (6MWT) is a common assessment of exercise-induced hypoxemia and exercise capacity used in patients with chronic fibrosing interstitial pneumonia (CFIP). However, whether the dynamic changes in SpO2 and heart rate during the 6MWT are associated with mortality in patients with CFIP has been undefined. METHODS This retrospective study enrolled 63 subjects with mild to severe CFIP who underwent the 6MWT. Subjects with CFIP were divided into 2 groups according to disease severity: mild, diffusing capacity of the lungs for carbon monoxide percentage predicted (%DLCO) > 55% and %FVC > 75%; and severe, %DLCO ≤ 55% and/or %FVC ≤ 75%. This study aimed to evaluate dynamic changes in the 6MWT including 6-min walk distance, change in SpO2 (ΔSpO2 ), SpO2 reduction time, SpO2 recovery time, change in heart rate (Δ heart rate), heart rate acceleration time, slope of heart rate acceleration, heart rate recovery at 1 min of rest after the 6MWT (HR-recovery), and dyspnea on exertion that are reflected by static pulmonary function and are related to exacerbation of CFIP and mortality. RESULTS Compared with subjects with mild CFIP, subjects with severe CFIP had significantly larger ΔSpO2 and longer SpO 2 reduction time and recovery time. The slope of heart rate, heart rate immediately after the 6MWT, and HR-recovery were lower in subjects with severe CFIP than in those with mild CFIP. In multiple regression analysis, percent vital capacity was significantly associated with SpO2 reduction time, and %DLCO was significantly associated with ΔSpO2 and SpO2 recovery time. Subjects with ΔSpO2 of > 10% and SpO2 recovery time of > 79 s had a significantly higher risk for exacerbation and mortality. CONCLUSIONS Dynamic changes in SpO2 and heart rate during the 6MWT were associated with risk for exacerbation and mortality in subjects with CFIP. Impaired dynamic response of SpO2 could reflect likelihood of exacerbation and increased mortality in CFIP.

Abstract
An intradialytic systolic blood pressure (SBP) decline, which defines intradialytic hypotension, may be associated with higher all-cause mortality. However, in Japanese patients on hemodialysis (HD), the association between intradialytic SBP decline and patient outcomes is unclear. This retrospective cohort study included 307 Japanese patients undergoing HD over 1 year in three dialysis clinics and evaluated the association between the mean annual intradialytic SBP decline (predialysis SBP-nadir intradialytic SBP) and clinical outcomes, including major adverse cardiovascular events (MACEs; cardiovascular death, nonfatal myocardial infarction or unstable angina, stroke, heart failure, and other severe cardiovascular events requiring hospitalization) by following up for 2 years. The mean annual intradialytic SBP decline was 24.2 (25-75th percentile, 18.3-35.0) mmHg. In the model fully adjusted for intradialytic SBP decline tertile group (T1, <20.4 mmHg; T2, 20.4 to <29.9 mmHg; T3, ≥29.9 mmHg), predialysis SBP, age, sex, HD vintage, Charlson comorbidity index, ultrafiltration rate, use of renin-angiotensin system inhibitors, corrected calcium, phosphorus, human atrial natriuretic peptide, geriatric nutritional risk index, normalized protein catabolism rate, C-reactive protein, hemoglobin, and use of pressor agents, Cox regression analyses showed that the hazard ratio (HR) was significantly higher for T3 than for T1 for MACEs (HR, 2.38; 95% confidence interval 1.12-5.09) and all-cause hospitalization (HR, 1.68; 95% confidence interval 1.03-2.74). Therefore, in Japanese patients on HD, a greater intradialytic SBP decline was associated with worse clinical outcomes. Further studies are warranted to investigate whether interventions to attenuate the intradialytic SBP decline will improve the prognosis of Japanese patients on HD.

Abstract
BACKGROUND While the efficacy of immune checkpoint inhibitors (ICIs) reportedly varies among metastatic sites and progression patterns (classified as systemic progression [SP] or mixed progression [MP]), the clinical efficacy of ICIs against gastric cancer remains unclear. The response to nivolumab depending on metastatic site and clinical outcomes according to progression pattern in patients with advanced gastric cancer was investigated retrospectively. METHODS Seventy-four advanced gastric cancer patients with measurable lesions who received nivolumab monotherapy between 2015 and 2020 were enrolled. Progression-free survival (PFS), overall survival, response at each metastatic site, and clinical outcomes according to progression pattern were analyzed retrospectively. SP and MP were defined as progression in more than half of the lesions and progression in half or fewer of the lesions, respectively, in cases evaluated as progressive disease. RESULTS Thirty-five (47%) and 27 (36%) patients had SP and MP, respectively, and 12 (16%) patients experienced no progression. The progression rates of target lesions in the lung (44%) and liver (57%) were significantly higher than that in the lymph nodes (18%) (lung vs. lymph node, p < 0.001; liver vs. lymph node, p = 0.03). Patients with MP had superior PFS to those with SP (median, 2.6 vs. 1.5 months; HR, 0.42; 95% CI, 0.23-0.76; p = 0.004). In MP group, patients with treatment beyond progression (TBP) with nivolumab had a trend of longer post-progression survival than those without TBP (median, 8.0 vs. 4.0 months; HR, 0.55; 95% CI, 0.23-1.29; p = 0.161). CONCLUSION Patients with MP had a longer PFS than those with SP. Lung and liver metastases had a poorer response to an ICI than lymph node metastases.

Abstract
425 Background: Blocking immune checkpoint (IC) pathways, particularly mediated by PD1 and PDL1, has attracted great attention as a promising strategy for treating gastrointestinal cancer. However, the clinical responses are low in many cases, and thus a new treatment strategy and its biomarker are urgently needed for improving the clinical outcome. Blocking other IC molecules, including LAG3, has been evaluated in many clinical trials, while the therapeutic efficacy and the predictive biomarkers remains to be determined due to the same issues as anti-PD1/PDL1 therapy. Methods: We analyzed soluble LAG3 (sLAG3) in sera by ELISA, and LAG3+ cells by flow cytometry, using fresh peripheral blood (PB) obtained from 91 patients with advanced gastric cancer (AGC) before and about one month after nivolumab monotherapy (2 courses) in the WJOG10417GTR study, according to the protocol approved by the IRB (August 2018 - November 2020). Progression-free survival (PFS) and overall survival (OS) were compared between high/low groups divided by the cutoff value determined by visually assessing the continuous trend and change point of log hazard ratios obtained by applying penalized splines to each molecular marker. This study was supported by ONO PHARMACEUTICAL CO., LTD. and Bristol Myers Squibb. Results: Posttreatment values were significantly more associated with patients’ prognosis rather than baseline values, and the sLAG3-high group showed significantly shorter PFS/OS as compared to the low group divided by the median: median PFS (mPFS) 51.5 vs 95.5 days (HR = 2.04, P = 0.002), and median OS (mOS) 188 vs 393 days (HR = 1.81, P = 0.032). Patients with high levels of LAG3+ PBCs after treatment showed worse prognosis as compared to those with low levels divided by the cutoff values: a CD3+CD4+LAG3+ T-cell subset, mPFS 43 vs 72 days (HR = 2.23, P = 0.015) and mOS 178 vs 282 days (HR = 1.56, P = 0.249); a CD3+CD8+LAG3+ T-cell subset, mPFS 57 vs 69 days (HR = 1.89, P = 0.012) and mOS 228 vs 303 days (HR = 1.40, P = 0.233); and a CD56+LAG3+ NK subset, mPFS 57 vs 88 days (HR = 2.15, P = 0.003) and mOS 217 vs 409 days (HR = 1.88, P = 0.031). Patients with sLAG3-high/CD56+LAG3+ NK-high levels showed markedly worse prognosis than those with low/low levels (mPFS-HR = 10.55, P < 0.001; and mOS-HR = 4.59, P < 0.001). Conclusions: Patients with posttreatment high levels of sLAG3 and LAG3+ cells in PB showed poor prognosis of AGC patients after the nivolumab therapy, suggesting that these are useful predictive biomarkers. LAG3 may be a promising target in immunotherapy for AGC. Clinical trial information: UMIN000032686 .

Abstract
Pathological examination of formalin-fixed paraffin-embedded (FFPE) needle-biopsied samples by certified pathologists represents the gold standard for differential diagnosis between ductal carcinoma in situ (DCIS) and invasive breast cancers (IBC), while information of marker metabolites in the samples is lost in the samples. Infrared laser-scanning large-area surface-enhanced Raman spectroscopy (SERS) equipped with gold-nanoparticle-based SERS substrate enables us to visualize metabolites in fresh-frozen needle-biopsied samples with spatial matching between SERS and HE staining images with pathological annotations. DCIS (n = 14) and IBC (n = 32) samples generated many different SERS peaks in finger-print regions of SERS spectra among pathologically annotated lesions including cancer cell nests and the surrounding stroma. The results showed that SERS peaks in IBC stroma exhibit significantly increased polysulfide that coincides with decreased hypotaurine as compared with DCIS, suggesting that alterations of these redox metabolites account for fingerprints of desmoplastic reactions to distinguish IBC from DCIS. Furthermore, the application of supervised machine learning to the stroma-specific multiple SERS signals enables us to support automated differential diagnosis with high accuracy. The results suggest that SERS-derived biochemical fingerprints derived from redox metabolites account for a hallmark of desmoplastic reaction of IBC that is absent in DCIS, and thus, they serve as a useful method for precision diagnosis in breast cancer.

Abstract
PURPOSE This study aimed to reveal the impact of coronavirus disease 2019 on the number of practices commonly used for cancer diagnosis in Japan. METHODS The sampling dataset of the National Database of Japan from January 2015 to January 2021 was used to generate 25-point time-series data for the number of practices (21 points before and 4 points during the pandemic outbreak). The decreased number was estimated by interrupted time-series analysis using a seasonal autoregressive integrated moving average model. Using the pre-pandemic data, expected counterfactual numbers during the pandemic were predicted, and decreased rate was calculated. RESULTS In most practices, the number dramatically decreased in the early stage of the pandemic and recovered rapidly thereafter. As of April 2020, gastric endoscopy decreased at the top of the practices (- 42.1%, with 95% confidence intervals of - 50.5% and - 33.7%), followed by gastric biopsy (- 38.6%, with 95% confidence intervals of - 46.7% and - 30.6%). The period of declined practices for lung cancer was relatively prolonged. The number of sentinel lymph node biopsies for breast cancer and colposcopies and biopsies for cervical cancer did not decrease in April 2020, but significantly decreased later in July 2020, which is assumed to be the time lapse after the primary testing before surgical treatment or intense scrutiny. CONCLUSION In general, the number of practices for cancer diagnosis in Japan showed only a temporary decline, which was concordant with reports from several other countries.

Abstract
In this study, we sought to elucidate the roles of the interleukin (IL)-32β and IL-32γ in mesothelioma cell growth, and vascular endothelial growth factor (VEGF)-A and C-X-C motif chemokine ligand 8 (CXCL8) expression. IL-32 elicited a growth-promoting effect against one of the six mesotheliomas lines and exerted diverse regulatory functions in VEGF-A and CXCL8 secretion from mesotheliomas stimulated with or without IL-17A. Retroviral-mediated transduction of mesothelioma lines with IL-32γ resulted in enhanced IL-32β expression, which facilitated or suppressed the in vitro growth, and VEGF-A and CXCL8 expression. Overexpressed IL-32β-augmented growth and VEGF-A and CXCL8 production were mainly mediated through the phosphatidylinositol-3 kinase (PI3K) signaling pathway. On the other hand, overexpressed IL-32β-deceased growth was mediated through mitogen-activated protein kinase (MAPK) pathway. NCI-H2373IL-32γ tumors grew faster than NCI-H2373Neo tumors in a xenograft model, which was associated with increased vascularity. These findings indicate that IL-32 are involved in the regulation of growth and angiogenic factor production in mesotheliomas.

Abstract
OBJECTIVE We aim to investigate the quantity and quality of scientific evidence dealing with comprehensive health issues of working women in occupational health. METHODS This scoping review of original articles that investigated comprehensive health issues of working women aged 19-64 years in Japan was published in PubMed (1967-2022) and Igaku Chuo Zasshi (or Ichu-shi, 1982-2022). Using identical broad search terms, we first identified 17 122 English and 6154 Japanese articles. We excluded those with clinically relevant topics, or ethnicity other than Japanese and included 853 English and 855 Japanese articles for review and classified them into nine research areas considered to be critical factors for women in the workforce and five study design groups to investigate the quality of the evidence accumulated. RESULTS Among 853 English-language articles in PubMed, "Mental health" was the most frequent area studied, followed by "Work-related disease" and "Lifestyle-related disease." Among 855 Japanese-language articles from Ichu-shi, "Mental health" was the most frequently studied area followed by "Work and balance," and "Work-related disease." "Infertility, pregnancy, and childbirth" and "Menstruation, menopause, and genital disease" were well studied in Ichu-shi but scarcely published in PubMed. "Harassment and discrimination" were sparsely reported in both databases. As for research designs, many articles in both PubMed and Ichu-shi employed descriptive or cross-sectional study designs. However, a few studies employed cohort/longitudinal or interventional studies. CONCLUSION The results underscored the need for higher-quality study designs with more scientific evidence on working women's health in the field of occupational health.

Abstract
BACKGROUND Caregivers of people with dementia frequently experience an elevated level of psychological distress and burden. This study aimed to examine the effectiveness of a group-format multi-component programme which is based on cognitive behavioural therapy and positive psychology. METHODS Family caregivers of dementia were allocated (1:1) to the intervention group and the wait-list control group, stratified by age (<65 years, ≥65 years) and care status (at home or in an institution). The intervention group received a six-session, 10-week, group-format programme. The primary outcome was the Hospital Anxiety Depression Scale (HADS). Secondary outcomes were the short-version of the Zarit Burden Interview (personal strain and role strain), Neuropsychiatric Inventory Questionnaire, Dementia Caregiver Positive Feeling Scale, and Self-Compassionate Reactions Inventory. The evaluations were conducted at baseline, 10 weeks (post-intervention), and 14 weeks (follow-up). RESULTS The analyses were performed with 64 registered participants. In the whole sample, no significant effect was observed on HADS. There was medium effect on role strain (P = 0.04, partial η2 = 0.08). Positive feelings of caregiving increased after the intervention but were not maintained at follow-up. In the subgroup analysis of caregivers under 65 years of age, a statistically significant effect was observed for personal strain (P = 0.03, partial η2 = 0.16). An interaction effect was also found for the total score of positive feelings of caregiving (P < 0.05, partial η2 = 0.02) and the meaning of caregiving (P = 0.02, partial η2 = 0.10). CONCLUSIONS This programme did not show significant improvement in depression and anxiety of caregivers of dementia; however, it reduced the burden of their role conflict (role strain) and yielded favourable short-term effects on the positive feelings and the meaning of caregiving among the participants. Also, the programme effectively reduced the personal strain of caregivers under 65 years.

Abstract
BACKGROUND Accelerated tumor growth during immunotherapy in pre-existing measurable lesions, hyperprogressive disease (HPD), has been reported. However, progression of non-measurable lesions and new lesions are frequently observed in patients with advanced gastric cancer (AGC). METHODS This retrospective study involved AGC patients at 24 Japanese institutions who had measurable lesions and received nivolumab after ≥ 2 lines of chemotherapy. HPD was defined as a ≥ two-fold increase in the tumor growth rate of measurable lesions. The pattern of disease progression was classified according to new lesions in different organs and ascites appeared/increase of ascites. RESULTS Of 245 patients, 147 (60.0%) showed progressive disease (PD) as the best response and 41 (16.7%) showed HPD during nivolumab monotherapy. There was no significant difference in overall survival (OS) between patients with HPD and those with PD other than HPD (median OS 5.0 vs 4.8 months; hazard ratio [HR] 1.0, 95% confidence interval [CI] 0.6-1.5; p = 1.0). Fifty-three patients developed new lesions in different organs and 58 had appearance/increase of ascites; these patients showed shorter OS than those without each of these features (median OS 3.3 vs 7.1 months, HR 1.8, 95% CI 1.2-2.7, p = 0.0031 for new lesions, and 3.0 vs 7.8 months, HR 2.6, 95% CI 1.8-3.8, p < 0.0001 for ascites). Thirty-one patients who had both features showed the worst prognosis (median OS 2.6 months). CONCLUSIONS New lesions in different organs and appearance/increase of ascites, rather than the original definition of HPD, are the patterns of disease progression associated with poor prognosis in AGC patients receiving nivolumab whose best response was PD.

Abstract
BACKGROUND The real-world survival benefit of FOLFOXIRI (fluorouracil, leucovorin, oxaliplatin, and irinotecan) plus anti-VEGF therapy (Triplet) over doublet chemotherapy (Doublet) remains controversial in patients with BRAFV600E mutant metastatic colorectal cancer (mCRC). PATIENTS AND METHODS WJOG13219G was a multicenter, retrospective, registry-based study of patients with BRAFV600E mutant mCRC who received first-line triplet or doublet chemotherapy from January 2014 to December 2019 in Japan. Inverse probability of treatment weighting (IPTW) was used to adjust for patient background. RESULTS The analysis included 79 and 91 patients in the Triplet and Doublet groups, respectively. The Triplet group was significantly younger and had better performance status. No statistical difference was noted in progression-free survival (PFS; HR, 0.82; 95% CI, 0.60-1.13; P = .22) and overall survival (OS; HR, 0.88; 95% CI, 0.62-1.25; P = .48) between both groups. IPTW analysis also showed no difference between the 2 groups in PFS (HR, 0.86; 95% CI, 0.69-1.08; P = .20) and OS (HR, 0.93; 95% CI, 0.73-1.20; P = .59). The Triplet and Doublet groups had an objective response rate of 53% and 41%, respectively (P = .10). At least one grade 3 or 4 adverse event was seen in 51 (65%) and 43 (47%) patients in the Triplet and Doublet groups, respectively, with the incidence of neutropenia being significantly higher in the former. CONCLUSION Triplet therapy had no survival benefit versus doublet therapy in the overall and IPTW cohorts or specific subgroups for real-world patients with BRAFV600E mutant mCRC.

Abstract
In Japan, active recommendation of the human papillomavirus vaccine was withheld between 2013 and 2021 due to adverse reaction reports. This resulted in low vaccine coverage with reports from less than 1%. This study aimed to investigate if knowledge and health-belief related factors associated with vaccine intention among young adolescents with the hope that our findings may be helpful in promotion campaigns. We recruited students in four colleges and universities in Akita Prefecture from 2020 to 2021 who had never been vaccinated. A total of 318 students (male 54%, mean age 21 years) responded to a self-administered questionnaire; only 6% reported immediate vaccine intention, and 61% reported no such intention or "do not know." The correct percentages of 20-item knowledge about HPV vaccine-related morbidity, mortality, and prevention were very low regardless of gender (average males 41.4% vs. females 39.6%). Multivariable logistic regression models demonstrated that in males, higher levels of literacy, perceived susceptibility, and place for vaccination (logistical barrier) were associated with HPV vaccine intention, whereas "no need now" was associated with less intention. In females, a higher level of knowledge was significantly associated with vaccine intention, whereas "concerns of adverse effects" were associated with less intention.

Abstract
Although fluoropyrimidine plus oxaliplatin is the standard of care for stage III colon cancer, fluoropyrimidine alone is also recommended for stage III patients in Japanese and other practice guidelines. We assessed efficacy of adjuvant fluoropyrimidine with or without oxaliplatin across a population of patients with stage III colon cancer in the Multi-Institutional Registry of Large Bowel Cancer in Japan. From the registry, we analyzed 6,834 stage III colorectal cancer patients. Approximately 70% of colorectal cancer patients received some form of chemotherapy. Of these, we analyzed those who received adjuvant chemotherapy between 2008 and 2011. Based on the TNM classification, the 5-year overall survival rates of colon and rectal cancer after the covariate adjustment by regimens of adjuvant chemotherapy were 95.7% with fluoropyrimidines and 90.6% with oxaliplatin-combined therapy at stage IIIA (Stratified log-rank P < 0.001), 86.5% and 80.8% at stage IIIB (P < 0.001), and 72.1% and 70.7% at stage IIIC (P < 0.001), respectively. Oxaliplatin did not enhance efficacy with regard to relapse-free survival as well as overall survival. Adjuvant fluoropyrimidine monotherapy and fluoropyrimidine plus oxaliplatin show comparable efficacy benefits for the treatment of stage III of Japanese colon cancer patients. This supports the use of fluoropyrimidine alone as a standard option for this patient group in Japan.

Abstract
Abstract
Background
Atrial fibrillation (AF) is a well-known risk factor for heart failure (HF), and HF development as a complication of AF is associated with a decline in the quality of life and poor prognosis. However, unlike thrombotic events, incidence of HF in patients with AF has not changed for decades, and a preventive strategy has yet to be developed.
Purpose
We sought to develop a risk model for new-onset HF admission in patients with AF and without a history of HF. Additionally, we attempted to externally validate the developed risk model.
Methods
We utilized two multicenter, prospective, observational registries of AF and analyzed the patients without a history of AF. One of which is defined as a derivation cohort, which included 2,857 patients, and the other is defined as a validation cohort, which included 2,516 patients. We developed a risk model by selecting variables with regularized regression and weighing coefficients by Cox regression analysis with the derivation cohort. The external validity was tested in the validation cohort.
Results
During the follow-up period, 148 patients (5.2%) in the derivation cohort and 104 patients (4.1%) in the validation cohort developed HF during the median follow-up period of 1,396 (interquartile range [IQR]: 1,078–1,820) days and 1,168 (IQR: 844–1,309) days, respectively. In the derivation cohort, four predictors (age, hemoglobin, serum creatinine, and log-transformed brain natriuretic peptide) were identified as potential risk factors for HF development. The developed risk model showed good discrimination and calibration in both the derivation (area under the curve [AUC], 0.77 [95% confidence interval (CI) 0.73–0.81]; Hosmer-Lemeshow test, P=0.257) and validation cohorts (AUC: 0.76 [95% CI 0.72–0.81]; Hosmer-Lemeshow test, P=0.475). Considering death not due to HF as a competing risk, the cumulative incidence curves for HF admission stratified by the risk score were generated, which showed higher HF hospitalization rate for the higher risk score categories.
Conclusion
The newly developed risk model with four readily available clinical characteristics and biomarkers performed well in the prediction of new-onset HF admission of patients with AF in both derivation and validation cohort.

Abstract
Abstract
Introduction
Recent studies reported that a convolutional neural network (CNN; a deep learning model) can detect elevated pulmonary artery wedge pressure (PAWP) from chest radiographs, the diagnostic images most commonly used for assessing pulmonary congestion in heart failure. However, no method has been published for quantitatively estimating PAWP from such radiographs. We hypothesized that a regression CNN, an alternative type of deep learning, could be a useful tool for quantitatively estimating PAWP from chest radiographs in cardiovascular diseases.
Methods
We retrospectively enrolled 936 patients with cardiovascular diseases who had undergone right heart catheterization (RHC) and chest radiography and estimated PAWP by constructing a regression CNN based on the VGG16 model. We randomly categorized 80% of the data as training data (training group, n=748) and 20% as test data (test group, n=188). Moreover, we tuned the learning rate–one of the model parameters–by 5-hold cross-validation of the training group. Correlations between PAWP measured by RHC (ground truth [GT] PAWP) and PAWP derived from the regression CNN (estimated PAWP) were tested. To visualize how the regression CNN assessed the images, we created a regression activation map (RAM), a visualization technique for regression CNN.
Results
Estimated PAWP correlated significantly with GT PAWP in both the training (r=0.76, P<0.001) and test group (r=0.62, P<0.001). Bland-Altman plots found a mean (SEM) difference between GT and estimated PAWP of −0.23 (0.16) mm Hg in the training and −0.05 (0.41) mm Hg in the test group. The RAM showed that our regression CNN model estimated high PAWP by focusing on the cardiomegaly and pulmonary congestion. In the test group, the area under the curve (AUC) for detecting elevated PAWP (≥18 mm Hg) produced by the regression CNN model was similar to the AUC of an experienced cardiologist (0.86 vs 0.83, respectively; P=0.24).
Conclusion
This proof-of-concept study shows that regression CNN can quantitatively estimate PAWP from standard chest radiographs in cardiovascular diseases.

Abstract
BACKGROUND RSPO fusions that lead to WNT pathway activation are potential therapeutic targets in colorectal cancer (CRC), but their clinicopathological significance remains unclear. METHODS We screened 1019 CRCs for RSPO fusions using multiplex reverse transcription-PCR. The RSPO fusion-positive tumours were subjected to whole-exome sequencing (WES). RESULTS Our analysis identified 29 CRCs with RSPO fusions (2.8%), consisting of five with an EIF3E-RSPO2 fusion and 24 with PTPRK-RSPO3 fusions. The patients were 17 women and 12 men. Thirteen tumours (45%) were right-sided. Histologically, approximately half of the tumours (13/29, 45%) had a focal or extensive mucinous component that was significantly more frequent than the RSPO fusion-negative tumours (13%; P = 8.1 × 10-7). Four tumours (14%) were mismatch repair-deficient. WES identified KRAS, BRAF, and NRAS mutations in a total of 27 tumours (93%). In contrast, pathogenic mutations in major WNT pathway genes, such as APC, CTNNB1 and RNF43, were absent. RSPO fusion status did not have a statistically significant influence on the overall or recurrence-free survival. These clinicopathological and genetic features were also confirmed in a pooled analysis of previous studies. CONCLUSION RSPO fusion-positive CRCs constitute a rare subgroup of CRCs with several characteristic clinicopathological and genetic features.

Abstract
Variations in dose prescription methods in stereotactic body radiotherapy (SBRT) for early stage non-small-cell lung cancer (ES-NSCLC) make it difficult to properly compare the outcomes of published studies. We conducted a comprehensive search of the published literature to summarize the outcomes by discerning the relationship between local control (LC) and dose prescription sites. We systematically searched PubMed to identify observational studies reporting LC after SBRT for peripheral ES-NSCLC. The correlations between LC and four types of biologically effective doses (BED) were evaluated, which were calculated from nominal, central, and peripheral prescription points and, from those, the average BED. To evaluate information on SBRT for peripheral ES-NSCLC, 188 studies were analyzed. The number of relevant articles increased over time. The use of an inhomogeneity correction was mentioned in less than half of the articles, even among the most recent. To evaluate the relationship between the four BEDs and LC, 33 studies were analyzed. Univariate meta-regression revealed that only the central BED significantly correlated with the 3-year LC of SBRT for ES-NSCLC (p = 0.03). As a limitation, tumor volume, which might affect the results of this study, could not be considered due to a lack of data. In conclusion, the central dose prescription is appropriate for evaluating the correlation between the dose and LC of SBRT for ES-NSCLC. The standardization of SBRT dose prescriptions is desirable.

Abstract
3610 Background: A fluoropyrimidine plus oxaliplatin is the standard of care for stage III colon cancer but a fluoropyrimidine alone is also recommended for stage III patients in Japanese and other practice guidelines. We assessed efficacy of adjuvant fluoropyrimidine with or without oxaliplatin across a population of stage III colon patients in the Multi-Institutional Registry of Large Bowel Cancer in Japan. Methods: 7,024 of stage III colorectal cancer patients in this registry were analyzed. Endpoints were relapse-free survival (RFS) and overall survival (OS). Results: All patients received adjuvant chemotherapy between 2008 and 2011.Patient characteristics except lymph node metastases were well balanced across groups. The RFS of fluoropyrimidine with or without oxaliplatin show comparable efficacy for stage III, even for stage IIIc patients, less than 70 years old, and T4 or N2b. Median follow-up was 74.9 months in oxaliplatin combined therapy and 74.7 months in fluoropyrimidine monotherapy. The additive efficacy of oxaliplatin was not shown for RFS and OS. Conclusions: Adjuvant fluoropyrimidine monotherapy and fluoropyrimidine plus oxaliplatin show comparable efficacy benefits for the treatment of stage III of Japanese colon cancer patients; supporting fluoropyrimidine alone as standard options for the adjuvant therapy of stage III in Japan.

Abstract
INTRODUCTION Recently, the incidence of cervical cancer has increased in Japan, probably because of an interruption in human papillomavirus (HPV) vaccination and a low cervical cancer screening rate. There is a lack of evidence for self-sampling HPV testing as a cervical cancer screening tool in Japan. The Accelerating Cervical Cancer Elimination by Self-Sampling test trial aims to compare the effectiveness of screening using the self-sampling HPV test with that of routine screening concerning screening uptake and precancer detection. METHODS AND ANALYSIS This trial has a single-municipality, open-label, parallel, superiority and randomised design. Approximately 20 000 women who have not undergone cervical cancer screening for at least 3 years will be assigned randomly to the self-sampling arm and the control arm using a 1:1 ratio. Participants assigned to the control arm will undergo routine cervical cancer screening (cytology test) provided by Ichihara City, while those assigned to the self-sampling arm will choose the routine screening or self-sampling HPV test. HPV tests will be performed using the cobas 8800 system (Roche Diagnostics, Rotkreuz, Switzerland). Participants who will undergo the self-sampling HPV testing will be recommended to undergo routine screening. The results of the cytology test and further tests, such as colposcopy and biopsy, will be collected and used for this trial. The risk ratio and risk difference in the proportion of participants with cervical intraepithelial neoplasia two or worse between the two arms will be calculated. The test for the null hypothesis (the detection rates are equal between the two arms) will be performed using Pearson's χ2 test. ETHICS AND DISSEMINATION This trial was approved by the Research Ethics Committees of the Chiba Foundation for Health Promotion and Disease Prevention and the collaborating research institutes. The results will be disseminated through peer-reviewed journals and conference presentations. TRIAL REGISTRATION NUMBER jRCT1030200276. Pre-results.

Abstract
37 Background: The survival benefit of FOLFOXIRI plus bevacizumab (Triplet) over Doublet in patients (pts) with BRAFV600E-mutant metastatic colorectal cancer (mCRC) remains controversial. We compared Triplet therapy with Doublet and explored the pts subgroups that could benefit from intensive chemotherapy (chemo) using real-world data. Methods: WJOG13219G was a multicenter, retrospective registry-based study of pts with BRAFV600E-mutant mCRC who received first-line doublet or triplet chemo with/out molecular targeted agents in January 2014–December 2019. Primary analysis focused on pts who received VEGF inhibitor-containing chemo. To adjust pts background, the inverse probability of treatment weighting (IPTW) method based on propensity scores calculated by age, ECOG PS, and disease status (recurrent/metastatic) was used. Results: A total of 232 pts from 33 hospitals were registered. After excluding 18 pts treated with anti-EGFR antibody-containing regimen and 44 without any targeted agents, 79 pts with Triplet and 91 with Doublet were analyzed. Baseline pts disposition was as follows: median age, 61 y; male proportion, 51%; PS 0/1/≥2, 63%/32%/5%; recurrent/metastatic, 26%/74%; and right/left primary, 68%/32%. Significant differences were noted in age and PS between the two groups. At median follow-up of 24.0 months, no statistical difference was noted in progression-free survival (PFS) (median 9.7 months of Triplet vs. 7.8 months of Doublet, HR = 0.89, P = 0.49) and overall survival (OS) (median 18.7 vs. 18.3 months, HR = 0.87, P = 0.52). The objective response rate was 53% in the Triplet group and 41% in Doublet (P = 0.10). Curative surgery after chemo was more frequent in the Triplet group than in Doublet (13% vs. 3%, P = 0.02). Two pts (3%) in the Triplet group and 6 (7%) in Doublet received immunotherapy as subsequent chemo; 13 (16%) and 6 (7%) also received BRAF inhibitor-containing therapy. IPTW analysis showed no difference between the two groups in PFS (HR = 0.82, P = 0.07) and OS (HR = 0.92, P = 0.57). In the subgroup analysis, pts with right-sided primary tumor in the Triplet group showed favorable trends of PFS (HR, 0.87; 95% CI, 0.65–1.16) and OS (HR, 0.71; 95%CI, 0.50–1.01), whereas pts with left-sided tumor in the Triplet group showed the reverse trends of PFS (HR, 1.17; 95% CI, 0.77–1.78) and OS (HR, 1.68; 95% CI, 0.97–2.91). Conclusions: Some baseline characteristics were significantly different between real-world pts in the Triplet and Doublet groups. Although the Triplet group did not show any survival benefit compared with Doublet in the original and IPTW cohorts, pts with right-sided BRAFV600E-mutant mCRC could benefit from Triplet therapy.

Abstract
286 Background: The standard neoadjuvant chemotherapy (NAC) in Japan for locally advanced esophageal squamous cell carcinoma (ESCC) consists of CDDP + 5-FU (CF). Recently, neoadjuvant DTX plus CF (DCF) therapy has shown promising efficacy for locally advanced ESCC. In addition, immune checkpoint inhibitors (ICIs) have demonstrated a survival benefit in ESCC and potential as an NAC in several cancers, including lung, breast, skin, and bladder. We previously reported that neoadjuvant CF plus nivolumab (Nivo) therapy was tolerable and showed promising efficacy for ESCC; however, the efficacy of ICI with DCF as an NAC and the safety of subsequent surgery for ESCC patients remain unclear. Methods: FRONTiER is a multi-cohort phase I study designed to evaluate the safety and efficacy of ICI combined with NAC in ESCC. The eligibility criteria were histologically proven ESCC with cT1N1-3M0 or cT2-3N0-3M0 (8th-UICC TNM classification), patient age of 20-75 years, PS ≤1, and no prior cancer therapies. The primary endpoint was the incidence of dose-limiting toxicities (DLT) from the initial dose to the 30th postoperative day. This study contained 5 experimental cohorts: cohort C received 3 courses of DTX (70 mg/m2), CDDP (70 mg/m2), and Nivo (360 mg/body) on day 1 and 5-FU (750 mg/m2) on days 1–5 every three weeks. Cohort D received one administration of Nivo (240 mg/body) 2 weeks before chemotherapy followed by the same regimen as cohort C. Results: Twelve patients were enrolled in cohort C (n = 6) and D (n = 6) (median age [range]: 60 [31-74] years, PS 0/1: 11/1, clinical stage I/II/III/IVA: 2/2/7/1). Only one patient in cohort D developed DLT (grade 3 dyspnea and rash); no other DLT were seen. Grade ≥3 adverse events were neutropenia (n = 1), leukopenia (n = 7), anorexia (n = 3), hyponatremia (n = 2), febrile neutropenia (n = 1), nausea (n = 1), and lymphopenia (n = 1) during NAC, and lung infection (n = 2), peritoneal infection (n = 1), anemia (n = 1), lymph leakage (n = 1), vagal reflex (n = 1), dyspnea (n = 1), rash (n = 1), septic shock (n = 1), pleural effusion (n = 1), and pneumatosis intestinalis (n = 1) during the postoperative period. No treatment-related deaths were observed. All patients received 3 courses of NAC, and 11 patients (91.7%) achieved an R0 resection without treatment interruption. One patient (16.7%) in cohort C and 3 patients (50.0%) in cohort D achieved pathological complete responses. Conclusions: Neoadjuvant DCF + Nivo with/without prior Nivo administration followed by surgery for locally advanced ESCC was well tolerated and showed an extremely promising efficacy. Clinical trial information: NCT03914443.

Abstract
258 Background: An acceleration of tumor growth during immunotherapy, (hyperprogressive disease [HPD]: defined as >2 times increase in tumor growth rates during nivolumab compared with prior chemotherapy, Champiat S, 2017) has been reported. We reviewed the prevalence and clinical outcomes of HPD in AGC patients treated with nivolumab, and reported that there were no differences either in progression-free survival (PFS) or overall survival (OS) between patients with HPD and those with PD other than HPD (Suzuki T, ASCO Gastrointestinal Cancers Symposium 2020). Then, we hypothesized that PD in unmeasurable lesion (ascites representing peritoneal metastasis) and appearance of new lesions, which are not included in definition of HPD, might have influenced the prognosis of AGC. Methods: The subjects of this retrospective study were 245 AGC patients with measurable disease who received nivolumab after failure of >2 chemotherapy regimens, and their responses were assessed at least 3 times (during prior therapy, before and after nivolumab) in 24 institutions. We explored the impact on prognosis of HPD, new lesion, increase of ascites in AGC patients receiving nivolumab 3 mg/kg or 240 mg/body intravenously every 2 weeks. We divided patients to 4 group according to new lesions at different organ/increase of ascites: Group (G) 1 (-/-), G 2 (+/-), G 3 (-/+), G 4 (+/+). Results: One hundred forty-seven patients (60%) showed PD, and their PFS and OS were 1.5 months(M) and 4.8 M, while those of 41 patients (16.7%) with HPD were 1.4 M and 5.0 M. Fifty-three patients showed appearance of new lesions at different organ and 58 patients showed increase of ascites (31 patients showed both). Survival outcomes of the 4 groups are shown in the Table. Patients with appearance of new lesions at different organ showed shorter prognosis compared with patients without it (median OS: G 2+4 vs G 1+3, 3.3 M vs 7.1 M; hazard ratio [HR], 1.8 [95% CI: 1.2–2.7]; p = 0.003). Also, patients with increase of ascites showed shorter prognosis compared to patients with stable/decrease of ascites (median OS: G 3+4 vs G 1+2, 3.0 M vs 7.8 M; HR, 2.6 [95% CI: 1.8–3.8]; p < 0.001). More of patients with increase of ascites could not receive subsequent chemotherapy after disease progression than others (G 1+2 vs G 3+4, 51.7% [46/89] vs 75.9% [44/58]; p = 0.03). Large tumor size, number of prior lines of chemotherapy, and high neutrophil-to-lymphocyte ratio at baseline were associated with G 4. Conclusions: Appearance of new lesions at different organ and increase of ascites, not HPD, were disease progression pattern associated with poor prognosis in AGC patients receiving nivolumab.[Table: see text]

Abstract
We present an experimental method to generate quasiperpendicular supercritical magnetized collisionless shocks. In our experiment, ambient nitrogen (N) plasma is at rest and well magnetized, and it has uniform mass density. The plasma is pushed by laser-driven ablation aluminum (Al) plasma. Streaked optical pyrometry and spatially resolved laser collective Thomson scattering clarify structures of plasma density and temperatures, which are compared with one-dimensional particle-in-cell simulations. It is indicated that just after the laser irradiation, the Al plasma is magnetized by a self-generated Biermann battery field, and the plasma slaps the incident N plasma. The compressed external field in the N plasma reflects N ions, leading to counterstreaming magnetized N flows. Namely, we identify the edge of the reflected N ions. Such interacting plasmas form a magnetized collisionless shock.

Abstract
Although many screening tools for delirium are available, delirium is still occasionally overlooked or misdiagnosed. One of the reasons for this is the lack of brief screening tools that do not require specialized training to use. The 4 'A's test (the 4AT) is a validated screening tool for delirium that can be administered in a very short time without specialized training. Herein, we evaluated the reliability and validity of the Japanese version of the 4AT (the 4AT-J). A total of 150 patients aged ≥ 65 years were enrolled. Their demographics and clinical characteristics were obtained within 24 hr of their hospitalization. On each patient's high-risk day of developing delirium, the 4AT-J was administered by a nurse, and the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-Ⅴ) and the Japanese version of Delirium Rating Scale-Revised-98 (DRS-98-J) were administered by a psychiatrist. Our analyses revealed that when a cut-off score of 4, the 4AT-J showed high sensitivity and specificity. The Cronbach's α-coefficient was similar to that of the original version. A receiver operating curve analysis showed sufficient power of the 4AT-J to discriminate delirium. The 4AT-J showed adequate reliability and validity for delirium screening in elderly patients.
