Abstract
Inflammatory skin diseases are known to negatively impact patient psychology, with individuals experiencing higher rates of stress and subsequent diminished quality of life, as well as mental health issues including anxiety and depression. Moreover, increased psychological stress has been found to exacerbate existing inflammatory skin diseases. The association between inflammatory skin diseases and psychological stress is a timely topic, and a framework to better understand the relationship between the two that integrates available literature is needed. In this narrative review article, we discuss potential neurobiological mechanisms behind psychological stress due to inflammatory skin diseases, focusing mainly on proinflammatory cytokines in the circulating system (the brain-gut-skin communications) and the default mode network in the brain. We also discuss potential descending pathways from the brain that lead to aggravation of inflammatory skin diseases due to psychological stress, including the central and peripheral hypothalamic-pituitary-adrenal axes, peripheral nerves and the skin barrier function.

Abstract
The loss of the Y chromosome (ChrY), also known as LOY, is a common genetic alteration observed in men. It occurs in non-neoplastic cells as an age-related change as well as in neoplastic cells of various cancer types. While well-documented in humans, LOY has not been extensively studied in non-human mammals. In this study, we developed simple digital PCR-based assays to assess the copy number of ChrY relative to the X chromosome (ChrX) and chromosome 8 (Chr8) to evaluate ChrY numerical alterations in male canine DNA specimens. Using these assays, we analyzed non-neoplastic leukocytes from 162 male dogs without hematopoietic neoplasia to investigate the occurrence of age-related LOY in non-neoplastic leukocytes. Additionally, we examined 101 tumor DNA specimens obtained from male dogs diagnosed with various types of lymphoma and leukemia to determine whether copy number alterations of the ChrY occur in canine hematopoietic cancers. Analysis of the 162 non-neoplastic leukocyte DNA specimens from male dogs of varying ages revealed a consistent ∼1:1 ChrY:ChrX ratio. This suggests that age-related LOY in non-neoplastic leukocytes is rare or absent in dogs. Conversely, a decreased or increased ChrY:ChrX ratio was detected in canine neoplastic leukocytes at varying frequencies across different canine hematopoietic malignancies (P = 0.01, Fisher's exact test). Notably, a higher incidence of LOY was observed in more aggressive cancer types. To determine if this relative LOY to ChrX was caused by changes in ChrY or ChrX, we further analyzed their relative copy numbers using Chr8 as a reference. Loss of ChrX relative to Chr8 was found in 21% (9/41) of B-cell lymphomas and 6% (1/18) of non-T-zone/high-grade T-cell lymphomas. In contrast, a subset (29%, 4/14) of T-cell chronic lymphocytic leukemia showed gain of ChrX relative to Chr8. Notably, no relative LOY to Chr8 was detected indolent hematopoietic cancers such as T-zone lymphoma (0/9) and chronic lymphocytic leukemia of B-cell (0/11) and T-cell origins (0/14). However, relative LOY to Chr8 was present in more aggressive canine hematopoietic cancers, with incidences of 24% (10/41) in B-cell lymphoma, 44% (8/18) in non-T-zone/high-grade T-cell lymphoma, and 75% (6/8) in acute leukemia. This study highlights both similarities and differences in LOY between human and canine non-neoplastic and neoplastic leukocytes. It underscores the need for further research into the role of ChrY in canine health and disease, as well as the significance of LOY across various species.

Abstract
BACKGROUND Diagnosing biliary tract cancer is difficult because endoscopic retrograde cholangiopancreatography (ERCP) is performed fluoroscopically, and the sensitivity of bile cytology is low. Liquid biopsy of bile using targeted sequencing is expected to improve diagnosis and treatment, but few studies have been conducted. In this study, we examined whether liquid biopsy of bile improves the diagnostic sensitivity of biliary strictures. METHODS A total of 72 patients with biliary strictures who underwent ERCP at Chiba University Hospital between April 2018 and March 2021 were examined. Of these, 43 and 29 were clinically and pathologically diagnosed as having malignant and benign biliary strictures, respectively. We performed targeted sequencing of bile obtained from these patients, and the sensitivity of this method was compared with that of bile cytology. Detection of at least one oncogenic mutation was defined as having malignancy. RESULTS The sensitivity of bile cytology was 27.9%, whereas that of genomic analysis was 46.5%. Comparing bile cytology alone with the combination of cytology and genomic analysis, the latter was more sensitive (53.5%, p < .001). Among the 43 patients with malignant biliary strictures, mutations with FDA-approved drugs were detected in 11 (26%). CONCLUSIONS Liquid biopsy of bile can potentially diagnose malignancy and detect therapeutic targets.

Abstract
OBJECTIVES Pancreatic cancer (PC) has a poor prognosis and limited treatment options. Liquid biopsy, which analyzes circulating tumor DNA (ctDNA) in blood, holds promise for precision medicine; however, low ctDNA detection rates pose challenges. This study aimed to investigate the utility of wash samples obtained via endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) as a liquid biopsy for PC. METHODS A total of 166 samples (42 formalin-fixed paraffin-embedded [FFPE] tissues, 80 wash samples, and 44 plasma samples) were collected from 48 patients with PC for genomic analysis. DNA was extracted and quantified, and 60 significantly mutated genes were sequenced. The genomic profiles of FFPE tissues, wash samples, and plasma samples were compared. Finally, the ability to detect druggable mutations in 80 wash samples and 44 plasma samples was investigated. RESULTS The amount of DNA was significantly lower in plasma samples than in wash samples. Genomic analysis revealed a higher detection rate of oncogenic mutations in FFPE tissues (98%) and wash samples (96%) than in plasma samples (18%) and a comparable detection rate in FFPE tissues and wash samples. Tumor-derived oncogenic mutations were detected more frequently in wash samples than in plasma samples. Furthermore, the oncogenic mutations detection rate remained high in wash samples at all PC stages but low in plasma samples even at advanced PC stages. Using wash samples was more sensitive than plasma samples for identifying oncogenic and druggable mutations. CONCLUSIONS The wash sample obtained via EUS-FNB is an ideal specimen for use as a liquid biopsy for PC.

Abstract
INTRODUCTION Respiratory infections are an ongoing global health challenge. The COVID-19 pandemic triggered global nonpharmacological measures that reshaped public health. In Japan, the shift from legal to individual discretion in pandemic management started on May 8, 2023. However, it still unknown how the relaxation of measures affects respiratory pathogens across age groups. METHODS We collected 16,946 samples from 13,526 patients between February 2020 and September 2023, analyzing the circulating respiratory pathogen dynamics using FilmArray respiratory panel. RESULTS Our analysis revealed significant increases in the positivity rates of respiratory pathogens across multiple age groups after relaxation. The pathogens including adenovirus, Bordetella pertussis, parainfluenza 2 and parainfluenza 4 showed increased positivity predominantly in children aged under 10 years. Conversely, some pathogens including human metapneumovirus, rhinovirus/enterovirus, and respiratory virus (RSV) increased in broad range of age groups. SARS-CoV-2 positivity rates decreased in children under 10 years but increased in those aged over 60 years. DISCUSSION Age-stratified analysis reveals a dynamic pattern of circulating pathogen in each age group after relaxation measures. This study provides essential epidemiologic data that can guide strategies to protect different age groups and effectively respond to respiratory infections in post-COVID-19 era.

Abstract
Background The infection status of healthcare workers (HCWs) with coronavirus disease 2019 has become a major concern worldwide. In this study, we investigated the efficacy of the number of vaccine doses on symptoms after BA.5-adapted bivalent vaccination in HCWs. Methods We analyzed the occupation, route of infection, symptoms, and vaccination history of all HCWs who tested positive for severe acute respiratory syndrome coronavirus 2 and worked in our hospital from November 2020 to March 2023. A logistic regression analysis was performed to examine the association between the presence of BA.5-adapted bivalent vaccination and symptoms. Results During the observation period, 531 HCWs became infected. Of these, 72 % were women, with a median age of 30 years. Nurses accounted for 57 % of the infected cases, and many of the infection routes were from family members. We examined the relationship between symptoms in 352 HCWs infected with the Omicron BA.5* variant and the number of vaccine doses. As the number of vaccine doses increased, the rate of fever decreased, while symptoms such as a runny nose and sore throat tended to increase. The logistic regression analysis showed that the rate of fever tended to decrease (odds ratio = 0.52, 95 % confidence interval: 0.26-1.01, p = 0.056) and that of a runny nose increased (odds ratio = 3.68, 95 % confidence interval: 1.17-10.6, p = 0.018) after BA.5-adapted bivalent vaccination. Conclusion This study shows that fever is reduced and mild symptoms are increased after BA.5-adapted bivalent vaccination in BA.5-infected HCWs. This result highlights the potential effectiveness of tailored vaccination strategies in the management of emerging COVID-19 variants.

Abstract
OBJECTIVE To determine the useful biomarker for predicting the effects of poly-(ADP ribose)-polymerase (PARP) inhibitors in Japanese patients with ovarian cancer. METHODS We collected clinical information and performed molecular biological analysis on 42 patients with ovarian, fallopian tube, and primary peritoneal carcinomas who received PARP inhibitors. RESULTS Among the analyzed patients with ovarian cancer, 23.8% had germline BRCA mutation (gBRCAm), 42.9% had homologous recombination repair-related gene mutation (HRRm), and 61.1% had a genomic instability score (GIS) of ≥42. Patients with HRRm had a significantly longer progression-free survival (PFS) than those without HRRm (median PFS 35.6 vs. 7.9 months; p=0.009), with a particularly marked increase in PFS in patients with gBRCAm (median PFS 42.3 months). Similarly, among patients with recurrent ovarian cancer, those with HRRm had a longer PFS than those without HRRm (median PFS 42.3 vs. 7.7 months; p=0.040). Multivariate Cox proportional hazards regression analysis found that performance status and gBRCAm status were independent factors associated with prolonged PFS with PARP inhibitors. In recurrent ovarian cancer, multivariate regression analysis identified platinum-free interval (PFI) in addition to performance status as a significant predictor of PFS. On the contrary, no significant association was observed between PFS and a GIS of ≥42 used in clinical practice. CONCLUSION We found that HRRm can be a useful biomarker for predicting the effects of PARP inhibitors in treating ovarian cancer and that the PFI can also be useful in recurrent ovarian cancer.

Abstract
BACKGROUND Obtaining sufficient tumor tissue for genomic profiling is challenging in pancreaticobiliary cancer (PBCA). We determined the utility of molecular barcoding (MB) of liquid biopsies (bile, duodenal fluid, and plasma) for highly sensitive genomic diagnosis and detection of druggable mutations for PBCA. METHODS Two in-house panels of 60 genes (non-MB panel) and 21 genes using MB (MB panel) were used for the genomic analysis of 112 DNA samples from 20 PBCA patients. We measured the yield of DNA and compared the genomic profiles of liquid samples obtained using the non-MB panel and the MB panel. The utility of the panels in detecting druggable mutations was investigated. RESULTS A significantly greater amount of DNA was obtained from bile supernatants and precipitates compared to tumor samples (P < 0.001 and P = 0.001, respectively). The number of mutations per patient was significantly higher using the MB panel than using the non-MB panel (2.8 vs. 1.3, P = 0.002). Tumor-derived mutations were detected more frequently using the MB panel than the non-MB panel (P = 0.023). Five drug-matched mutations were detected in liquid samples. CONCLUSIONS Liquid biopsy with MB may have utility in providing genomic information for the prognosis of patients with PBCA.

Abstract
Analyzing RNA samples from formalin-fixed paraffin-embedded (FFPE) tissues is essential for precision medicine. We investigated RNA quantity and quality from FFPE tumor tissues fixed in formalin for various times and compared sequencing metrics from next-generation sequencing (NGS). Hepatocellular carcinoma (HCC) tissues were fixed in 10% neutral buffered formalin (1-240 h) and FFPE blocks were prepared. Total RNA was extracted, and the quantity and quality were assessed using the NanoDrop, Qubit and Bioanalyzer. After preparing sequencing libraries, NGS was performed on the Oncomine Dx Multi-CDx system. Total RNA yields of all samples met the threshold required for NGS, but longer fixation times resulted in decreased total RNA and long RNA fragment (>200 nt) yields. NGS analysis showed fewer sequencing reads of internal control genes from RNA with longer fixation times. RNA extracted from FFPE blocks stored for 500 days had reduced RNA yield and quality compared with RNA obtained from FFPE blocks prepared immediately. In conclusion, short and over-fixation should be avoided because of their negative impact on sequencing quality. Fixation process should be finished promptly within recommended guidelines (6-72 h) for cancer patients.

Abstract
Intraductal papillary mucinous neoplasm of the pancreas (IPMN) is characterized by cystic dilatation of the pancreatic duct system, intraductal papillary growth, and excessive mucin secretion. Although IPMN is basically a benign disease and surgical resection is not necessary, it has the potential to develop into pancreatic cancer. We recently encountered a rare case of synchronous development of two different types of malignant lesions in the pancreas associated with IPMN derived from different clones. A 74-year-old Japanese woman developed a cystic lesion in her pancreatic tail. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) was performed on two low echoic lesions in the pancreatic tail (10 mm) and body (10 mm), which were then diagnosed as malignancies. After the surgically resected pancreas was carefully examined, in addition to the tail (10 mm) and body (10 mm) tumors, an intraductal papillary mucinous adenoma (IPMA) was observed, which was continuous to the tail tumor and extending toward the body of the pancreas but not contiguous to the body tumor. Genomic analysis using targeted sequencing revealed that the malignant lesion in the pancreatic tail and two sections of adjacent IPMA lesions in the pancreatic duct were almost identical. KRAS G12D, RNF43 G29fs, PBRM1 P1471R, and PIK3CA I1058L were shared, whereas only KRAS G12D was shared between the malignant lesion in the pancreatic body and others. Multiple pancreatic cancers may occur simultaneously and/or metachronously in the context of genomic alterations in IPMN.

Abstract
BACKGROUND AND AIM Little is known about genetic mutations in the regenerated mucosa (RM) after endoscopic resection (ER) of esophageal carcinoma. Thus, this study investigates the status of genetic variation in RM after ER of esophageal squamous cell carcinoma (ESCC). METHODS The study cohort included 19 patients with ESCC. We used an esophageal carcinoma panel to identify target sequences for squamous cell carcinoma (SCC), background mucosa (BM), and RM after ER of ESCC. We used OncoKB to check whether each mutation was a putative driver. RESULTS We identified 77 mutations of 32 genes in SCC, 133 mutations of 34 genes in BM, and 100 mutations of 29 genes in RM. Putative driver mutations were identified in 20 mutations in 14 cases in SCC, 16 mutations in 10 cases in BM, and 7 mutations in 11 cases in RM. The rate of putative driver mutations to total mutations was significantly lower in RM (26% in SCC vs 12% in BM vs 7% in RM, P = 0.009). Additionally, the rate of cases with TP53 putative driver mutations was significantly lower in RM (63% in SCC vs 37% in BM vs 16% in RM, P = 0.011). The percentage of putative driver mutations and the percentage of cases with a putative driver of TP53 were significantly lower in RM. CONCLUSION Esophageal RM after ER of ESCC could have a lower risk of carcinogenesis.

Abstract
Object Exclusively dopamine-producing pheochromocytoma/paraganglioma (PPGL) is an extremely rare subtype. In this condition, intratumoral dopamine β-hydroxylase (DBH), which controls the conversion of norepinephrine from dopamine, is impaired, resulting in suppressed norepinephrine and epinephrine production. However, the rarity of this type of PPGL hampers the understanding of its pathophysiology. We therefore conducted genetic and immunohistological analyses of a patient with an exclusively dopamine-producing paraganglioma. Methods Paraganglioma samples from a 52-year-old woman who presented with a 29.6- and 41.5-fold increase in plasma and 24-h urinary dopamine, respectively, but only a minor elevation in the plasma norepinephrine level was subjected to immunohistological and gene expression analyses of catecholamine synthases. Three tumors carrying known somatic PPGL-related gene variants (HRAS, EPAS1) were used as controls. Whole-exome sequencing (WES) was also performed using the patient's blood and tumor tissue. Results Surprisingly, the protein expression of DBH was not suppressed, and its mRNA expression was clearly higher in the patient than in the controls. Furthermore, dopa decarboxylase (DDC), which governs the conversion of 3,4-dihydroxyphenyl-L-alanine (L-DOPA) to dopamine, was downregulated at the protein and gene levels. In addition, melanin, which is synthesized by L-DOPA, accumulated in the tumor. WES revealed no PPGL-associated pathogenic germline variants, but a missense somatic variant (c.1798G>T) in CSDE1 was identified. Conclusion Although pre-operative plasma L-DOPA was not measured, our histological and gene expression analyses suggest that L-DOPA, rather than dopamine, might have been overproduced in the tumor. This raises the possibility of pathophysiological heterogeneity in exclusively dopamine-producing PPGL.

Abstract
BACKGROUND AND OBJECTIVE The Oncomine Dx Target Test (ODxTT) has been used as a companion diagnostic test for lung cancer. Here, we evaluated whether the amount of nucleic acid and the degree of RNA degradation are related to the success of the ODxTT. METHODS This study included 223 samples from 218 patients with lung cancer. For all samples, DNA and RNA concentrations were quantified using Qubit, and the degree of RNA degradation was evaluated using the Bioanalyzer. RESULTS Of the 223 samples, 219 samples were successfully analyzed in the ODxTT and four were not. DNA analysis failed in two samples, which were attributed to low DNA concentrations and both were cytology specimens. Meanwhile, RNA analysis failed in the other two samples. These samples had sufficient amounts of RNA, but it was highly degraded with DV200 (the percentage of RNA fragments > 200 base pairs) less than 30. Compared with RNA samples with DV200 ≥ 30, analysis of RNA with DV200 < 30 yielded significantly fewer reads for the internal control genes. This test showed actionable mutations were identified in 38% (83/218) of all patients and in 46.6% (76/163) of patients with lung adenocarcinoma. CONCLUSIONS DNA concentration and degree of RNA degradation are key factors determining the success of diagnostic testing by the ODxTT.

Abstract
Although many studies have been conducted on the increase in spike antibody levels after vaccination, there is insufficient prospective and longitudinal information on the BA.5-adapted bivalent vaccine up to the fifth vaccination. In this study, we conducted a follow-up study of spike antibody levels and infection history in 46 health care workers who received up to 5 vaccinations. Monovalent vaccines were administered for the first to fourth vaccinations, and a bivalent vaccine was administered for the fifth vaccination. 11 serum samples were collected from each participant, and antibody levels were measured in a total of 506 serum samples. During the observation period, 43 of the 46 health care workers had no infection history, and 3 had a history of infection. Spike antibody levels peaked at 1 week after the second booster vaccination and gradually declined until the 27th week after the second vaccination. After 2 weeks following the fifth BA.5-adapted bivalent vaccine, the spike antibody levels significantly increased (median: 23,756 [IQR: 16,450 to 37,326]), compared to those measured before vaccination (median: 9,354 [IQR: 5,904 to 15,784]) (paired Wilcoxon signed-rank test, P = 5.7 × 10-14). These changes in antibody kinetics were observed regardless of age or sex. These results suggest that booster vaccination increased the spike antibody levels. Regular vaccination is effective in maintaining long-term antibody levels. IMPORTANCE A COVID-19 bivalent mRNA vaccine was developed and administered to health care workers. The COVID-19 mRNA vaccine induces a robust antibody response. However, little is known about the antibody response to vaccines in serially collected blood samples from the same individuals. Here, we provide two-year follow-up data on the humoral immune response to COVID-19 mRNA vaccines in health care workers who received up to five vaccinations, including the BA.5-adapted bivalent vaccine. The results suggest that regular vaccination is effective in maintaining long-term antibody levels and have implications for vaccine efficacy and booster dose strategies in health care settings.

Abstract
BACKGROUND This study aimed to investigate the validity of pathological diagnosis of early CRC (E-CRC) from the genetic background by comparing data of E-CRC to colorectal adenoma (CRA) and The Cancer Genome Atlas (TCGA) on advanced CRC (AD-CRC). METHODS TCGA data on AD-CRC were studied in silico, whereas by next-generation sequencer, DNA target sequences were performed for endoscopically obtained CRA and E-CRC samples. Immunohistochemical staining of mismatch repair genes and methylation of MLH1 was also performed. The presence of oncogenic mutation according to OncoKB for the genes of the Wnt, MAPK, and cell-cycle-signaling pathways was compared among CRA, E-CRC, and AD-CRC. RESULTS The study included 22 CRA and 30 E-CRC lesions from the Chiba University Hospital and 212 AD-CRC lesions from TCGA data. Regarding the number of lesions with driver mutations in the Wnt and cell-cycle-signaling pathways, E-CRC was comparable to AD-CRC, but was significantly greater than CRA. CRA had significantly more lesions with a driver mutation for the Wnt signaling pathway only, versus E-CRC. CONCLUSIONS In conclusion, the definition of E-CRC according to the Japanese criteria had a different genetic profile from CRA and was more similar to AD-CRC. Based on the main pathway, it seemed reasonable to classify E-CRC as adenocarcinoma. The pathological diagnosis of E-CRC according to Japanese definition seemed to be valid from a genetic point of view.

Abstract
BACKGROUND Obtaining sufficient pancreaticobiliary tumor tissue for genomic profiling has limitations. Liquid biopsies using plasma do not provide sufficient sensitivity. Thus, this study aimed to determine the effectiveness of liquid biopsy between bile and plasma for identifying oncogenic and drug-matched mutations. METHODS This study created a panel of 60 significantly mutated genes specific to pancreaticobiliary cancer (PBCA) and used it for genomic analysis of 212 deoxyribonucleic acid (DNA) samples (87 bile supernatant, 87 bile precipitate, and 38 plasma) from 87 patients with PBCA. The quantity of extracted DNA from bile and plasma was compared, as were genomic profiles of 38 pairs of bile and plasma from 38 patients with PBCA. Finally, we investigated 87 bile and 38 plasma for the ability to detect druggable mutations. RESULTS The amount of DNA was significantly lower in plasma than in bile (p < .001). Oncogenic mutations were identified in 21 of 38 (55%) patients in bile and nine (24%) in plasma samples (p = .005). Bile was significantly more sensitive than plasma in identifying druggable mutations (p = .032). The authors detected 23 drug-matched mutations in combined bile and plasma, including five ERBB2, four ATM, three BRAF, three BRCA2, three NF1, two PIK3CA, one BRCA1, one IDH1, and one PALB2. CONCLUSIONS Liquid biopsy using bile may be useful in searching for therapeutic agents, and using the obtained genomic information may improve the prognoses of patients with PBCA. PLAIN LANGUAGE SUMMARY Genomic profiling of formalin-fixed paraffin-embedded tissues may provide actionable targets for molecular and immuno-oncological treatment. However, most pancreaticobiliary malignancies are unresectable and formalin-fixed paraffin-embedded tissues cannot be obtained. Although comprehensive genomic profiling tests using plasma have been used in recent years, the utility of those using bile is not clear. Our study revealed that bile identified more drug-matched mutations than plasma in advanced pancreaticobiliary cancer patients. Bile may help widen the patient population benefiting from targeted drugs.

Abstract
OBJECTIVE This study prospectively observed the incidence of all malignancies and the prognosis of all patients in a population of patients who achieved Sustained Virological Response (SVR) with a 100% capture rate. DESIGN A prospective study of 651 SVR cases was conducted from July 2013 to December 2021. The primary endpoint was the occurrence of all malignancies, and the secondary endpoint was overall survival. The cancer incidence during the follow-up period was calculated using the man-year method, and risk factors were analyzed. In addition, sex- and age-matched standardized mortality ratio (SMR) was used to compare the general population with the study population. RESULTS The overall median follow-up was 5.44 years. 107 malignancies occurred in 99 patients during the follow-up. The incidence of all malignancies was 3.94/100 person-years. The cumulative incidence was 3.6% at 1 year, 11.1% at 3 years, and 17.9% at 5 years, and continued to increase almost linearly. The incidence of liver cancer and non-liver cancer was 1.94/100 patient-years vs. 1.81%/100 patient-years. The 1-year, 3-year, and 5-year survival rates were 99.3%, 96.5%, and 94.4%, respectively. This life expectancy was compared to the standardized mortality ratio of the Japanese population, which proved non-inferior. CONCLUSION It was found that malignancies of other organs occur as frequently as hepatocellular carcinoma (HCC). Therefore, follow-up of patients who have achieved SVR should focus not only on HCC but also on malignant tumors of other organs, and lifelong follow could contribute prolonged life expectancy for the previously short-lived.

Abstract
Comprehensive cancer genome profiling (CGP) has been nationally reimbursed in Japan since June 2019. Less than 10% of the patients have been reported to undergo recommended treatment. Todai OncoPanel (TOP) is a dual DNA-RNA panel as well as a paired tumor-normal matched test. Two hundred patients underwent TOP as part of Advanced Medical Care B with approval from the Ministry of Health, Labour and Welfare between September 2018 and December 2019. Tests were carried out in patients with cancers without standard treatment or when patients had already undergone standard treatment. Data from DNA and RNA panels were analyzed in 198 and 191 patients, respectively. The percentage of patients who were given therapeutic or diagnostic recommendations was 61% (120/198). One hundred and four samples (53%) harbored gene alterations that were detected with the DNA panel and had potential treatment implications, and 14 samples (7%) had a high tumor mutational burden. Twenty-two samples (11.1%) harbored 30 fusion transcripts or MET exon 14 skipping that were detected by the RNA panel. Of those 30 transcripts, 6 had treatment implications and 4 had diagnostic implications. Thirteen patients (7%) were found to have pathogenic or likely pathogenic germline variants and genetic counseling was recommended. Overall, 12 patients (6%) received recommended treatment. In summary, patients benefited from both TOP DNA and RNA panels while following the same indication as the approved CGP tests. (UMIN000033647).

Abstract
BACKGROUND Genomic profiling in lung cancer is essential for precision medicine. Cytological specimens provide an alternative to formalin-fixed paraffin-embedded (FFPE) samples for comprehensive genomic analysis. However, this approach remains challenging when a limited number of tumor cells are available. We applied whole genome amplification (WGA) to cytology specimens to overcome this limitation. METHODS Using a lung cancer panel targeting 58 genes, we performed next-generation sequencing of whole genome-amplified DNA extracted from cytological specimens containing 10-20 tumor cells (cyto-WGA) and DNA from corresponding FFPE tumor tissue. We compared sequencing data from cyto-WGA and FFPE samples to examine the detection accuracy of copy number variations and oncogenic and drug-matched variants. RESULTS The DNA quality and quantity from cyto-WGA were higher than those from FFPE samples (p < .0005 and p < .05, respectively). Sequencing metrics of cyto-WGA and FFPE tissues showed no difference in the number of mapped reads and mean coverage depth, but there were significant differences in the on-target rate (p < .05) and uniformity (p < .0005). Copy number variations in cyto-WGA samples (n = 211) were higher than in FFPE samples (n = 9) (p < .0001). Fourty nine oncogenic variants were detected in cyto-WGA and 39 in FFPE. Of these variants, 34 (63%) were present in both samples. In addition, all 16 drug-matched variants were detected in FFPE and cyto-WGA samples with 100% concordance. CONCLUSION Cyto-WGA can be a feasible and alternative method to detect oncogenic and drug-matched variants.

Abstract
OBJECTIVE Elucidation of clonal origin of synchronous endometrial and ovarian cancers (SEOs). METHODS We reviewed 852 patients who diagnosed endometrial and/or ovarian cancer. Forty-five (5.3%) patients were diagnosed as SEOs. We evaluated blood and tissue samples from 17 patients. We analyzed the clonal origins of 41 samples from 17 patients by gene sequencing, mismatch microsatellite instability (MSI) polymerase chain reaction assay and immunohistochemical (IHC) staining of 4 repair genes. RESULTS Sixteen of 17 patients had at least 2 or more trunk mutations shared between endometrial and ovarian cancer suggesting the identical clonal origins. The shared trunk mutation are frequently found in endometrial cancer of the uterus, suggesting the uterine primary. Four out of 17 (24%) SEOs had mismatch repair (MMR) protein deficiency and MSI-high (MSI-H) states. One case was an endometrial carcinoma with local loss of MSH6 protein expression by IHC staining, and the result of MSI analysis using the whole formalin-fixed, paraffin-embedded specimen was microsatellite stable. In contrast, ovarian tissue was deficient MMR and MSI-H in the whole specimen. This indicated that MMR protein deficiency could occur during the progression of disease. CONCLUSION Most SEOs are likely to be a single tumor with metastasis instead of double primaries, and their origin could be endometrium. In addition, SEOs have a high frequency of MMR gene abnormalities. These findings not only can support the notion of uterine primary, but also can help to expect the benefit for patients with SEOs by immuno-oncology treatment.

Abstract
BACKGROUND It is not clear whether archived cytological specimens (ACSs) obtained with endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) with rapid onsite evaluation (ROSE) can be used for genomic profiling of tumors. We used ACSs to perform genomic analysis of specimens to identify oncogenic and druggable mutations. METHODS A panel of 60 significantly mutated genes specific to pancreatobiliary cancer was created and used for genomic analysis of 113 specimens of 44 formalin-fixed paraffin-embedded (FFPE) tissues and 69 ACSs obtained by EUS-FNA with ROSE were included. The quantity and quality of DNA extracted from FFPE tissues and ACSs were compared. We also compared DNA from spray and touch ACSs. Next, genomic profiles were compared. We also evaluated detection of target gene mutations in each specimen. RESULTS The amount of DNA in FFPE tissues was greater than in ACSs (P = 0.014), but the quality of DNA was comparable (P = 0.378). There was no quantitative or qualitative difference between spray and touch ACSs (P = 0.154 and P = 0.734, respectively). Oncogenic mutations were shared at 82 % in FFPE tissues and ACSs and 82 % in spray and touch ACSs. The sensitivity of genomic analysis in ACSs was 97 % (67 of 69), which was comparable to that of cytology (62 of 69, 90 %; P = 0.165), and was significantly higher than that of histology (32/44, 73 %; P < 0.001). Drug-matched mutations were identified in five of the 44 lesions (11 %). CONCLUSION Genomic analysis of ACSs is useful in the prognosis of pancreatic cancer because detection of driver mutations is similar to detection in FFPE tissues.

Abstract
OBJECTIVES Recently, the Omicron strain of SARS-CoV-2 has spread and replaced the previously dominant Delta strain. Several Omicron sublineages (BA.1, BA.1.1, and BA.2) have been identified, with in vitro and preclinical reports showing that the pathogenicity and therapeutic efficacy differs between BA.1 and BA.2. We sought to develop a TaqMan assay to identify these subvariants. METHODS A TaqMan assay was constructed for rapid identification and genotyping of Omicron sublineages with 171 samples. We analyzed three characteristic mutations of the spike gene, Δ69-70, G339D, and Q493R, by TaqMan assay. The accuracy of the TaqMan assay was examined by comparing its results with the results of whole genome sequencing (WGS) analysis. RESULTS A total of 171 SARS-CoV-2 positive samples were analyzed by WGS and TaqMan assay. The 127 samples determined as BA.1/BA.1.1 by WGS were all positive for Δ69-70, G339D and Q493R by TaqMan assay. A total of 42 samples, determined as BA.2 by WGS, were negative for Δ69-70 but positive for G339D and Q493R by TaqMan. Two samples with G339N were determined to be inconclusive by the TaqMan method. Except for these two samples, the concordance rate between WGS and the TaqMan assay was 100% (169/169). CONCLUSION TaqMan assays targeting characteristic mutations are useful for identification and discrimination of Omicron sublineages.

Abstract
It is well-known that sustained virological response (SVR) by interferon (IFN)-based therapy against hepatitis C virus (HCV) infection reduced the incidence of hepatocellular carcinoma (HCC). However, whether IFN-free direct-acting antivirals reduce the risk of HCC is controversial. Therefore, this study aims to compare the incidence of HCC after the achievement of SVR between sofosbuvir combined with ledipasvir (SOF/LDV) and simeprevir with pegylated interferon plus ribavirin (Sim+IFN). Japanese patients with HCV infection (genotype 1) who achieved SVR between January 2013 and December 2014 by SOF/LDV (NCT01975675, n = 320) or Sim+IFN (000015933, n = 289) therapy in two nationwide, multicenter, phase III studies were prospectively monitored for the development of HCC by ultrasonography for 5 years after the end of treatment (EOT). No HCC was detected before the treatment. HCC was detected in 9 and 7 patients in the SOF/LDV and the Sim+IFN group in 5 years, respectively. The cumulative incidences of HCC rates 1, 3, and 5 years after EOT were similar between the two groups (1.5%, 2.7%, and 3.2% for the SOF/LDV and 1.8%, 2.8%, and 3.0% for the Sim+IFN group, respectively). No HCC was developed 3.5 years after EOT. Interestingly, a retrospective careful review of imaging taken before therapy revealed hepatic nodules in 50% of HCC patients, suggesting HCC was pre-existed before therapy. In conclusion, we could not find any differences in the incidence of HCC after the HCV eradication between the two therapeutic regimens, suggesting no enhancement of HCC development by DAA.

Abstract
BACKGROUND Genomic profiling of tumors is available, but whether the small fragment obtained via endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is sufficient for these examinations is unknown. Here we investigated whether EUS-FNB specimens are suitable for genomic profiling to identify oncogenic and drug-matched mutations. METHODS We constructed a pancreatobiliary cancer panel for targeted panel sequencing that covered 60 significantly mutated genes and compared the results with those of whole-exome sequencing (WES). In total, 20 and 53 formalin-fixed paraffin-embedded tissues obtained via surgery and EUS-FNB were analyzed, respectively. First, we examined the DNA quality and genomic profiles of 20 paired samples from 20 malignant lesions obtained via surgery and EUS-FNB. We then tested 33 samples obtained via EUS-FNB from 24 malignant and 9 benign lesions for the discrimination of malignancy. Finally, we explored drug-matched mutations from EUS-FNB specimens. RESULTS Although the DNA quantity obtained via surgery was higher than that obtained via EUS-FNB (P = 0.017), the DNA quality and mean depth were equivalent (P = 0.441 and P = 0.251). Panel sequencing of EUS-FNB specimens identified more oncogenic mutations than WES (90 % vs. 50 %). Furthermore, the number of oncogenic mutations did not differ between EUS-FNB and surgically resected specimens. Genomic profiling of EUS-FNB specimens enabled the discrimination of malignancy with 98 % accuracy. Of 44 malignant lesions, drug-matched alterations were identified in 14 % (6/44) of malignant lesions. CONCLUSION EUS-FNB specimens can be widely utilized for diagnostic purposes, discrimination of malignancy, and detection of drug-matched mutations for the treatment of pancreatic cancer.

Abstract
In 2008, a familial noradrenergic pheochromocytoma (PCC) with a KIF1B germline mutation in exon 41 was reported in a 24-year-old female proband and her family. However, in 2020, the same research group reported that the cause of PCC in this family was a MAX germline mutation and was not due to the KIF1B mutation. In this study, we investigated the pathogenicity of a KIF1B germline mutation detected in a 26-year-old woman with juvenile-onset noradrenergic PCC. She was surgically treated and did not have a family history of PCC. We performed whole-exome sequencing, Sanger sequencing, and immunohistochemical and gene expression analyses of catecholamine-synthesizing enzymes. Three tumors with associated somatic mutations were used as the control group. Whole-exome sequencing revealed a p.V1529M KIF1B germline mutation in exon 41 in our patient, and no other associated germline and somatic mutations, including MAX, were detected. Sanger sequencing confirmed the presence of both mutant and wild-type alleles in the tumor. Among the catecholamine-synthesizing enzymes, the expression of phenylethanolamine-N-methyl transferase was suppressed. An in silico analysis of the p.V1529M mutation showed a score suggestive of pathogenicity. After evaluation with the international guideline for sequence variants, p.V1529M mutation was still classified as a variant with uncertain significance; however, our data, including the in silico analysis data, provided certain evidences that met the criteria supporting its pathogenicity. Therefore, this study can support future studies in proving the pathogenicity of the KIF1B p.V1529M mutation.

Abstract
BACKGROUND The objective of this study was to identify the clinical utility of genomic analysis of ascitic fluid cytology (AC) in patients with epithelial ovarian cancer. METHODS Targeted next-generation sequencing was used to analyze 66 samples from 33 patients who had ovarian (n = 23), fallopian tube (n = 2), and peritoneal (n = 8) carcinoma, and the concordance rate of molecular profiles was compared between surgically resected, formalin-fixed, paraffin-embedded (FFPE) tissues and AC samples. RESULTS In total, 159 mutations were identified (54 oncogenic mutations and 105 nononcogenic mutations) in 66 DNA samples (33 FFPE tissues and 33 AC samples) from 33 patients. Of the 159 mutations, 57 (35.8%) were shared between surgically resected FFPE tissues and AC samples. However, the concordance rate of the molecular profiles between the 2 was significantly higher for oncogenic mutations compared with nononcogenic mutations (85.1% vs 10.5%; P < .01). Indeed, the AC samples covered all oncogenic mutations (n = 46) that were detected in surgically resected specimens and identified additional mutations (n = 8). CONCLUSIONS The current results indicated that genomic analysis of AC can identify all of the genetic changes associated with epithelial ovarian cancer to understand tumor characteristics without interventional surgery or biopsy and may play an important role in developing personalized precision medicine.

Abstract
Evaluation of the status of mismatch repair (MMR) in tumors is crucial for determining the application of immune checkpoint inhibitors (ICIs). Conventional PCR (MSI-PCR) is the gold standard for confirming the MMR status. However, it requires visual confirmation and presents difficulties in determining MMR status. Immunohistochemistry (IHC) is a simple method and can confirming MMR protein expression in the whole tumor. We aim to investigate IHC is more suitable for evaluating MMR status in the tumor. We compared MSI-PCR and IHC by testing 319 samples from 284 patients across 14 cancer types. In discordant cases, we performed laser-capture microdissection and microsatellite instability assay by next-generation sequencing (MSI-NGS). The concordance rate between IHC and MSI-PCR testing was 98.1% (313/319). Two reasons for these discrepancies were ambiguous MSI-PCR results and heterogeneous MSI status within the tumor. Among six cases (1.9%), three were judged as MSI-H by MSI-PCR but with proficient MMR by IHC. The results of MSI-NGS revealed microsatellite stable in these three cases. The remaining three cases, two of three were MSI-H and one was MSS in whole tumor in MSI-PCR. IHC showed a "mosaic" pattern containing both proficient MMR and deficient MMR portions by IHC in all three cases. We performed microdissection and MSI-PCR and found intratumoral heterogeneity of MMR status. These results indicated the advantages of IHC and performed expanded samples (n = 1082) and two additional mosaic cases were identified. Our results clearly indicated that simple IHC is the best choice for determining MMR alterations in critical cases for ICIs treatment.

Abstract
Simple Summary This study aims to detect cell-free DNA released from lung cancer cells into the airway using the ex vivo BAL model of our own establishing. We finally demonstrated that cell-free DNA released from lung cancer cells is more abundant in the airway than in the blood, and the efficient collection of cell-free DNA derived from lung cancer in the airway by BAL and its genomic analysis could allow the accurate diagnosis of lung cancer. We believe that this approach will possibly make a breakthrough in the currently unsatisfactory diagnostic yield for lung cancer, since it is a new and constitutive diagnostic focusing on the gene mutations of lung cancer and their release into the airway in the form of cell-free DNA. Abstract Although bronchoscopy is generally performed to diagnose lung cancer, its diagnostic yield remains unsatisfactory. Assuming that lung cancer cells release cell-free DNA into the epithelial lining fluid, we hypothesized that lung cancer could be diagnosed by analyzing gene mutations in cell-free DNA in this fluid. This study included 32 patients with lung cancer who underwent surgery at our hospital. Bronchoalveolar lavage (BAL) was performed on the resected lung samples (ex vivo BAL model) after lobectomy. Each DNA sample (i.e., BAL fluid, primary lesion, and plasma) underwent deep targeted sequencing. Gene mutation analyses in the BAL fluid samples identified mutations identical to those in the primary lesions in 30 (93.8%) of 32 patients. In contrast, the microscopic cytology of the same BAL fluid samples yielded a diagnosis of lung cancer in only one of 32 patients, and the analysis of plasma samples revealed gene mutations identical to those in the primary lesions in only one of 32 patients. In conclusion, cell-free DNA released from lung cancer cells exists more abundantly in the airway than in the blood. The collection and analysis of the BAL fluid containing cell-free DNA derived from lung cancer can thus allow lung cancer diagnosis and the screening of driver mutations.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has circulated worldwide and causes coronavirus disease 2019 (COVID-19). At the onset of the COVID-19 pandemic, infection control measures were taken, such as hand washing, mask wearing, and behavioral restrictions. However, it is not fully clear how the effects of these non-pharmaceutical interventions changed the prevalence of other pathogens associated with respiratory infections. In this study, we collected 3,508 nasopharyngeal swab samples from 3,249 patients who visited the Yamanashi Central Hospital in Japan from March 1, 2020 to February 28, 2021. We performed multiplex polymerase chain reaction (PCR) using the FilmArray Respiratory Panel and singleplex quantitative reverse transcription PCR targeting SARS-CoV-2 to detect respiratory disease-associated pathogens. At least one pathogen was detected in 246 (7.0%) of the 3,508 samples. Eleven types of pathogens were detected in the samples collected from March-May 2020, during which non-pharmaceutical interventions were not well implemented. In contrast, after non-pharmaceutical interventions were thoroughly implemented, only five types of pathogens were detected, and the majority were SARS-CoV-2, adenoviruses, or human rhinoviruses / enteroviruses. The 0-9 year age group had a higher prevalence of infection with adenoviruses and human rhinoviruses / enteroviruses compared with those 10 years and older, while those 10 years and older had a higher prevalence of infection with SARS-CoV-2 and other pathogens. These results indicated that non-pharmaceutical interventions likely reduced the diversity of circulating pathogens. Moreover, differences in the prevalence of pathogens were observed among the different age groups.

Abstract
A 71-year-old man with a history of drug-induced interstitial pneumonia was diagnosed with COVID-19 infection and simultaneously found to have a pulmonary mass, suggesting a coexisting lung cancer. Approximately 1 month after COVID-19 pneumonia resolved, the patient electively underwent right upper lobectomy. Postoperatively, acute exacerbation of interstitial pneumonia occurred and the patient died on the fifteenth postoperative day. By quantitative reverse transcription polymerase chain reaction, high levels of COVID-19-derived RNA were detected in the specimen of lung parenchyma. Despite resolved COVID-19 infection, it may persist locally in the lungs, with the risk of acute exacerbation of interstitial pneumonia due to secondary stressors including surgery.

Abstract
Introduction In cases of lung tumors that occur after treatment for malignancies in other organs, the tumor may represent either a primary lung cancer or a solitary pulmonary metastasis from the other tumor. Because some lung tumors are difficult to differentiate on the basis of imaging and pathologic findings, treatment selection is often difficult. In this study, we attempted to make a genomic diagnosis of primary and metastatic lung tumors by analyzing tumor samples using next-generation sequencing and evaluated the efficacy and validity of the genomic diagnosis. Methods A total of 24 patients with a solitary lung nodule and a history of other malignancies were enrolled in this study. Tumor cells were selected from tissue samples using laser capture microdissection. DNA was extracted from those cells and subjected to targeted deep sequencing of 53 genes. Results The driver mutation profiles of the primary lung tumors were discordant from those of the primary tumors in other sites, whereas the mutation profiles of pulmonary metastases and previous malignancies were concordant. In all 24 patients, we could diagnose either primary lung cancer (six patients) or lung metastases (18 patients) on the basis of whether gene mutation profiles were concordant or discordant. In 12 patients (50.0%), discrepancies were observed between the genomic and clinical or histopathologic diagnoses. Conclusions In patients with a solitary lung lesion and a history of cancer, tumor-specific mutations can serve as clonal markers, affording a more accurate understanding of the pathological condition and thus possibly improving both treatment selection and patient outcome.

Abstract
Hepatitis B virus (HBV) infection is one of the serious health problems in the world as HBV causes severe liver diseases. Moreover, HBV reactivation has occasionally been observed in patients with resolved HBV infection and patients using immunosuppression and anticancer drugs. Large-scale hospital data focused on HBV infection and severe liver function were analyzed at our hospital, located in an urban area adjacent to Tokyo, the capital city of Japan. A total of 99,932 individuals whose blood samples were taken at 7,170,240 opportunities were analyzed. The HBV surface antigen (HBsAg)-positive group had a more frequent prevalence of patients with higher transaminase elevations than the HBsAg-negative group. However, among the HBsAg-negative group, patients who were positive for anti-HBV surface antibody and/or anti-HBV core antibody, had more severe liver conditions and fatal outcomes. More careful attention should be paid to alanine transaminase (ALT) elevations higher than 1000 IU/L in patients who had current and previous HBV infection.

Abstract
As a result of population growth and the development of tube wells, humans’ exposure to arsenic has increased over the past few decades. The natural course of organ damage secondary to arsenic exposure is not yet well understood. In Toroku, Japan, an arsenic mine was intermittently operated from 1920 to 1962, and residents were exposed to high concentrations of arsenic. In this paper, we analyzed 190 consecutive residents for whom detailed records of neurological symptoms and findings were obtained from 1974 to 2005. All participants were interviewed regarding the presence of general, skin, hearing, respiratory, and neurological symptoms. Neurological symptoms were classified into extremity numbness or pain, constipation, dyshidrosis, sensory loss, and muscle atrophy. Superficial and vibratory sensation was also evaluated. More than 80% of participants experienced extremity numbness, and numbness was the most common neurological symptom. Numbness was associated with superficial sensory disturbance, and was correlated with the subsequent development of other neurological symptoms, including autonomic and motor symptoms. No previous studies have investigated the natural course of chronic arsenic intoxication; thus, these data serve as a guide for detecting early symptoms due to arsenic exposure.

Abstract
BACKGROUND Currently, PCR assay is a golden standard for diagnosis of Covid-19. However, it needs nasopharyngeal swabs, expensive instruments and expertise. It even causes PCR errors. METHODS We validated the antibody assay (Roche) in 36 followed patients and 1879 controls (medical staffs). RESULTS Of 1879 medical staffs, only two (0.11%) were positive by Cut off Index (COI; 1.0) (mean ± SD, 0.094 ± 0.047). Thirty six patients were composed of three groups; Group A,4 from Diamond Princess cruise ship, Group B, 2 infected in Africa, and Group C, 30 infected in Japan. PCR assays were conducted at outside laboratories before and repeated in house after hospitalized. Of 36 at admission, positive antibody was seen in 4/4 from the ship, 0/2 from Africa, and 5/30 from Japan. Two from Africa showed the increase of COI and became positive on days 8 and 13. Thirty Japanese was divided in two groups, e.g., 23 showed dynamic increase of COI up to 84.4 within 3 days while active virus replication present (Group C). In remaining 7 (7/30, 23%) (Group C'), no rise of antibody nor positive in house PCR assays, indicative of false positive results of PCR at the beginning. CONCLUSION This antibody testing has a wide dynamic ranges of COI and, thus, could be utilized in the early infection phase. This may also compliment and even help to avoid possible PCR errors. Therefore, this can serve as a powerful diagnostic tool, needed in the frontline of the clinic and hospitals.

Abstract
Background Vaccines against severe acute respiratory syndrome coronavirus 2 can trigger acquired immunity in infection-naïve individuals and offer a path toward ending the coronavirus disease pandemic that began in 2019. However, the kinetics of early antibody responses in vaccinated individuals remain poorly understood. Method We followed BNT162b2 mRNA-vaccinated health care workers (HCWs, N=108) including 103 infection-naïve and five previously infected individuals. A total of 763 blood samples were collected weekly or hourly basis before and after vaccination. Serological analysis of anti-spike and anti-nucleocapsid antibodies was performed. Results Seroconversion occurred in all infection-naïve HCWs 3 weeks after the first dose (just before the second vaccination) and a marked boosting effect was observed at 4 weeks (1 week after the second dose). Among previously infected HCWs with pre-existing antibodies against the spike protein, a remarkable boosting effect was observed during the first week after vaccination, and a further increase in antibody titres was observed after the second dose. In one previously infected patient, daily blood sampling was conducted. Antibody titres began to increase 96 hours (4 days) after the first dose. Conclusion The BNT162b2 mRNA vaccine remarkably enhanced antibody responses after the second dose in infection-naïve individuals and after the first dose in previously infected HCWs of all ages and genders. Antibody titres decreased slightly after the 5th week post-vaccination. The robust boosting effect of immunisation suggests that increased antibody titres following exposure to the virus may restrict viral replication, prolong the incubation period, or lessen the severity of disease.

Abstract
The genetic characteristics of Barrett’s esophagus (BE) and esophageal adenocarcinoma (EAC) in the Japanese population is unclear. This study aims to investigate the genetic characteristics from nondysplastic BE (NDBE) to early EAC in Japan. Clinical information was collected. Moreover, the genetic profile of NDBE without concurrent dysplasia, early EAC, and surrounding BE were also investigated using endoscopic biopsy samples and formalin-fixed, paraffin-embedded specimens from Japanese patients by targeted next-generation sequencing. Immunohistochemical staining for p53 was also performed for EAC lesions. Targeted NGS was performed for 33 cases with 77 specimens. No significant difference exists in the NDBE group between the number of putative drivers per lesion in the short-segment Barrett’s esophagus (SSBE) and long-segment Barrett’s esophagus (LSBE) [0 (range, 0–1) vs. 0 (range, 0–1). p = 1.00]. TP53 putative drivers were found in two patients (16.7%) with nondysplastic SSBE. TP53 was the majority of putative drivers in both BE adjacent to EAC and EAC, accounting for 66.7% and 66.7%, respectively. More putative drivers per lesion were found in the EAC than in the NDBE group [1 (range, 0–3) vs. 0 (range, 0–1). p < 0.01]. The genetic variants of TP53 in the Japanese early EAC were similar to those in western countries. However, TP53 putative drivers were detected even in Japanese patients with nondysplastic SSBE. This is significant because such nondysplastic SSBE might have higher risk of progressing to high-grade dysplasia or EAC. The risks of progression may not be underestimated and appropriate follow-ups may be necessary even in patients with SSBE. Trial registration: This study was registered at the University Hospital Medical Information Network (UMIN000034247).

Abstract
BACKGROUND/AIM Barrett's esophagus (BE) is a precursor of esophageal adenocarcinoma (EAC). Therefore, an accurate diagnosis of BE is important for the subsequent follow-up and early detection of EAC. However, the definitions of BE have not been standardized worldwide; columnar-lined epithelium (CLE) without intestinal metaplasia (IM) and/or < 1 cm is not diagnosed as BE in most countries. This study aimed to clarify the malignant potential of CLE without IM and/or < 1 cm genetically. METHOD A total of 96 consecutive patients (including nine patients with EAC) who had CLE were examined. Biopsies for CLE were conducted, and patients were divided into those with IM and > 1 cm (Group A) and those without IM and/or < 1 cm (Group B). Malignant potential was assessed using immunochemical staining for p53. Moreover, causative genes were examined using next-generation sequencing (NGS) on ten patients without Helicobacter pylori infection and without atrophic gastritis. RESULT Of the 96 patients, 66 were in Group B. The proportion of carcinoma/dysplasia in Group A was significantly higher than that in Group B (26.7% in Group A and 1.5% in Group B; p < 0.01). However, one EAC patient was found in Group B. In the immunostaining study for non-EAC patients, an abnormal expression of p53 was not observed in Group A, whereas p53 loss was observed in three patients (4.6%) in Group B. In the NGS study, a TP53 mutation was found in Group B. CONCLUSION CLE without IM and/or < 1 cm has malignant potential. This result suggests that patients with CLE as well as BE need follow-up.

Abstract
A 70-year-old man visited our hospital with a chief complaint of involuntary movements, diagnosed as chorea, involving the right upper and lower limbs. Brain MRI showed acute cerebral infarctions involving the left insular and parietal cortices. Chorea is usually due to dysfunction of components of the basal ganglia pathways, such as the caudate nucleus or subthalamic nucleus, and is rarely caused by lesions of the insular or parietal cortex. Here, we describe a case of cerebral infarctions in the left insular and parietal cortices and chorea of the right limbs, and discuss the relationship between the mechanism of chorea and insular and parietal cortical lesions.

Abstract
Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to spread worldwide. Here, we evaluated the performance of two quantitative antigen (Ag) tests, the Roche and Lumipulse Ag tests, using automated platforms. Methods We collected 637 nasopharyngeal swab samples from 274 individuals. Samples were subjected to quantitative reverse transcription PCR (RT-qPCR), the Roche Ag test and Lumipulse Ag test. Results When RT-qPCR was used as a reference, the overall concordance rate of the Roche Ag test was 77.1% (491/637) with 70.0% (341/487) sensitivity and 100% specificity (150/150). When inconclusive results of the Lumipulse Ag test were excluded, the overall concordance rate of the Lumipulse Ag test was 88.3% (467/529) with 84.8% (330/389) sensitivity and 97.9% (137/140) specificity. The overall concordance rate between the Roche and Lumipulse Ag tests was 97.9% (518/529) with 96.7% (322/333) sensitivity and 100% (196/196) specificity. Quantitative Ag levels determined using the Roche and Lumipulse Ag tests were highly correlated (R2 = 0.922). The Roche and Lumipulse Ag tests showed high concordance up to nine days after symptom onset, with progressively lower concordance after that. Conclusions The Roche and Lumipulse Ag tests showed equivalent assay performance and represent promising approaches for diagnosing coronavirus disease 2019.

Abstract
The ALK inhibitors are promising therapeutic agents against lung cancer harboring ALK fusion genes and are currently under development up to the third generation. However, its therapeutic effects are reported to be affected by differences in ALK variants and co-occurrent mutations. Materials and Methods; We experienced an autopsy case of an ALK-positive lung cancer patient who showed primary resistance to three generations of ALK inhibitors. The poor survival time of the case was 14 months. To reveal the mechanism of primary resistance to three generations of ALK inhibitors, we performed next generation sequencing for 12 specimes obtained from an autopsy with covering whole exons of 53 significantly mutated, lung cancer-associated genes and amplicon-based target RNA sequenceing for the ALK fusion gene. The NGS analysis revealed a rare variant.3 of ALK fusion, in which 30 bp of base was inserted at the end of ALK intron.19 and was associated with EML exon.6 [E6_ins30A20] and a co-occurrent oncogenic PIK3CA E542K mutation in all specimens. Structural analysis of the fusion protein ALK [E6_ins30A20] showed no interferance with the binding of ALK inhibitors to the kinase domain. The NGS analysis of primary and metastatic lesions obtained from an autopsy revealed a co-occurrent oncogenic PIK3CA E542K mutation in all specimens. The constitutive activation of PI3K-Akt signal by PIK3CA E542K mutation occurred downstream of ALK signaling pathway, could lead to primary resistance to ALK inhibitors in all generations.

Abstract
BACKGROUND/PURPOSE There are limitations in obtaining sufficient pancreaticobiliary tumor tissue for genomic profiling of tumors. Herein, we investigated whether archived cytological specimen (ACS) is suitable for genomic profiling to identify oncogenic and drug-matched mutations. METHODS We constructed a pancreaticobiliary cancer panel for targeted sequencing covering 60 significantly mutated genes (280 220 bp). Eighty DNA samples (19 formalin-fixed paraffin-embedded [FFPE] tissues and 61 ACS) from 44 patients with pancreaticobiliary disease were analyzed. We compared genomic profiles of 19 FFPE and 29 ACS from 19 patients with malignancies (Validation Cohort). We tested 32 ACS from 25 patients (15 malignant and 10 benign) for the ability to discriminate between malignant and benign disorders (Testing Cohort). We explored whether actionable and drug-matched mutations (Validation and Testing Cohorts) could be identified from ACS. RESULTS Oncogenic mutations observed in ACS were identical to those identified in FFPE specimens (76% consistency). Genomic profiling using only ACS discriminated between malignant and benign disorders with 93% accuracy, 91% sensitivity, and 100% specificity. Actionable and drug-matched mutations were identified in 74% and 32% of ACS, respectively, and in 79% and 21% in FFPE samples, respectively. CONCLUSION Archived cytological specimen may be used to discriminate malignancy and to detect drug-matched mutations in patients with advanced pancreaticobiliary cancer.

Abstract
Somatic mutations including the background mucosa in patients with Lugol-voiding lesions (LVLs) are still not well known. The aim of this study was to evaluate the somatic mutations of the background mucosa in patients with LVLs (Squamous cell carcinoma (SCC), intraepithelial neoplasia (IN), and hyperplasia). Twenty-five patients with LVLs (9 with SCC, 6 with IN, and 10 with hyperplasia) were included. A targeted sequence was performed for LVLs and background mucosa using an esophageal cancer panel. Each mutation was checked whether it was oncogenic or not concerning OncoKB. In LVLs, TP53 was the most dominant mutation (80%). Furthermore, 72% of TP53 mutations was putative drivers. In background mucosa, NOTCH1 was the most dominant mutation (88%) and TP53 was the second most dominant mutation (48%). Furthermore, 73% of TP53 mutations and 8% of NOTCH1 mutations were putative drivers. Putative driver mutations of TP53 had significantly higher allele frequency (AF) in SCC than in IN and hyperplasia. Conversely, putative driver mutations of NOTCH1 did not have a significant accumulation of AF in the progression of carcinogenesis. Furthermore, in SCC, AF of TP53 mutations was significantly higher in LVLs than in background mucosa, but not in IN and hyperplasia. Regarding NOTCH1, a significant difference was not observed between LVLs and background mucosa in each group. The background mucosa in patients with LVLs already had putative driver mutations such as TP53 and NOTCH1. Of these two genes, TP53 mutation could be the main target gene of carcinogenesis in esophageal SCC. Clinical Trials registry: UMIN000034247.
