Abstract
BACKGROUND Each method of reconstruction after gastrectomy results in a change in the digestive and absorptive status. However, there are few reports on the changes in pancreatic exocrine function after gastrectomy. We conducted this study to investigate the dynamics of pancreatic exocrine function after gastrectomy according to the method of reconstruction performed. METHODS The subjects of this study were 45 patients who underwent pancreatic exocrine function tests preoperatively and postoperatively, from among all patients who underwent gastrectomy for gastric cancer at our hospital between September, 2020 and March, 2022. We assessed pancreatic exocrine function using the Pancreatic Function Diagnostant (PFD) test. RESULT The mean preoperative PFD test result values for the distal gastrectomy (DG) Billroth I reconstruction (B-I) group and the DG Roux-en-Y reconstruction (R-Y) group were 62.6 and 67.3 (p = 0.36), respectively, and the mean postoperative PFD test result values for each group were 65.8 and 46.9 (p = 0.0094), respectively. A significant decrease in postoperative pancreatic function was observed in the DG R-Y group but not in the DG B-I group. The logistic regression analysis identified that age and the R-Y group were significantly correlated with a 10% decrease in the PFD value after gastrectomy. CONCLUSIONS Our study suggests that R-Y reconstruction may result in more impaired pancreatic exocrine function than B-I reconstruction.

Abstract
BACKGROUND Cancer-associated fibroblasts exhibit diversity and have several subtypes. The underlying relationship between the diversity of cancer-associated fibroblasts and their effect on gastric cancer progression remains unclear. In this study, mesenchymal stem cells were differentiated into cancer-associated fibroblasts with gastric cancer cell lines; clinical specimens were used to further investigate the impact of cancer-associated fibroblast diversity on cancer progression. METHODS Nine gastric cancer cell lines (NUGC3, NUGC4, MKN7, MKN45, MKN74, FU97, OCUM1, NCI-N87, and KATOIII) were used to induce mesenchymal stem cell differentiation into cancer-associated fibroblasts. The cancer-associated fibroblasts were classified based on ACTA2 and PDPN expression. Cell function analysis was used to examine the impact of cancer-associated fibroblast subtypes on cancer cell phenotype. Tissue samples from 97gastric patients who underwent gastrectomy were used to examine the clinical significance of each subtype classified according to cancer-associated fibroblast expression. RESULTS Co-culture of mesenchymal stem cells with nine gastric cancer cell lines revealed different subtypes of ACTA2 and PDPN expression in differentiated cancer-associated fibroblasts. Cancer-associated fibroblast subtypes with high ACTA2 plus PDPN expression levels significantly increased gastric cancer cell migration, invasion, and proliferation. The cancer-associated fibroblast subtype with ACTA2 plus PDPN expression was an independent prognostic factor along with lymph node metastasis for patients who had gastric cancer and were undergoing surgery. CONCLUSIONS Cancer-associated fibroblasts are educated by gastric cancer cells during the development of cancer-associated fibroblast diversity. Differentiated cancer-associated fibroblasts with distinct expression patterns could affect gastric cancer progression and enable prognostic stratification for gastric cancer.

Abstract
BACKGROUND It was reported that rikkunshito (TJ-43) improved the cisplatin-induced decreases in the active form of ghrelin in plasma; however, other effects on gastrointestinal hormones have not been investigated. AIM To investigate the effects of TJ-43 on peripheral levels of incretin hormones, including gastric inhibitory polypeptide (GIP) and glucagon-like polypeptide-1 (GLP-1), in humans and rats. METHODS Patients were divided into two groups, namely patients who received TJ-43 immediately following surgery [TJ-43(+) group] and those who received TJ-43 on postoperative day 21 [TJ-43(-) group], and the plasma levels of active GIP and active GLP-1 were assessed. In animal experiments, rats were treated with TJ-43 [rat (r)TJ-43(+) group] or without [rTJ-43(-) group] by gavage for 4 wk, and the plasma active GIP and active GLP-1 levels were measured. The expression of incretin hormones in the gastrointestinal tract and insulin in the pancreas were investigated by immunohistochemistry. Furthermore, the cyclic adenosine monophosphate activities were assessed in pancreatic tissues from rats treated with or without TJ-43 in vivo, and the blood glucose levels and plasma insulin levels were measured in rats treated with or without TJ-43 in oral glucose tolerance tests. RESULTS In humans, the active incretin hormone levels increased, and values were significantly greater in the TJ-43(+) group compared those in the TJ-43(-) group. In rats, the plasma active incretin levels significantly increased in the rTJ-43(+) group compared with those in the rTJ-43(-) group. GIP and GLP-1 expressions were enhanced by TJ-43 treatment. Moreover, plasma insulin levels increased and blood glucose levels were blunted in the rTJ-43(+) group. CONCLUSION The results show that TJ-43 may be beneficial for patients who undergo pancreatic surgery.

Abstract
BACKGROUND/AIM Cytoglobin (Cygb), a protein involved in cellular oxygen metabolism and protection, has garnered attention owing to its potential role in the initiation and progression of cancer, particularly colon cancer (CC). This study investigated the expression and significance of Cygb in CC. PATIENTS AND METHODS This study included 145 patients who underwent R0 surgery for CC (clinical stage II/III) at our institution between January 2007 and December 2014. Immunohistochemical analysis was performed to evaluate the Cygb expression patterns in CC tissues. Additionally, the correlation between Cygb expression levels and the clinicopathological characteristics of patients with CC was investigated. RESULTS Colon cancer tissues were categorized into high-expression (95 cases) and low-expression (50 cases) groups. Cygb was highly expressed in well-differentiated cases, whereas its expression decreased in poorly differentiated cases. No significant differences in other clinicopathological factors were observed between the two groups. Cygb expression had no significant effect on recurrence-free survival or overall survival. CONCLUSION This study contributes to the growing understanding of Cygb expression and its significance in CC. The expression of Cygb in CC was found to be unrelated to the recurrence rate and prognosis, but showed a correlation with differentiation status.

Abstract
BACKGROUND/AIM Aquaporins (AQPs) were initially discovered as water channel proteins that facilitate transcellular water movements. Recent studies have shown that AQPs are expressed and play an oncogenic role in various cancers. However, the expression and role of Aquaporin 4 (AQP4) in colon cancer have not been investigated. This study aimed to examine the clinical and pathophysiologic significance of AQP4 in colon cancer. PATIENTS AND METHODS Immunohistochemistry (IHC) of AQP4 for 145 primary tumor samples obtained from patients with stage II or III colon cancer was performed, and the relationship between AQP4 expression and patients' prognoses was analyzed. Knockdown experiments with AQP4 small interfering RNA using human colon cancer cells were conducted to analyze the effects on cell invasiveness. RESULTS IHC revealed that AQP4 was scarcely expressed in the noncancerous colonic mucosa. Of the 145 patients who enrolled in this study, 109 (75.2%) and 36 (24.8%) patients were classified as negative and positive for AQP4 expression, respectively. A high level of AQP4 expression is significantly associated with deeper tumors with lymph node metastasis and venous invasion. A 5-year progression-free survival rate of AQP4-positive patients was significantly worse than that of AQP-4 negative patients (70.7% vs. 87.0%, p=0.049). Furthermore, AQP4 knockdown significantly inhibited cell migration and invasion in HCT116 cells. CONCLUSION AQP4 may be a novel biomarker and therapeutic target for colon cancer.

Abstract
Platelets form complexes with gastric cancer (GC) cells via direct contact, enhancing their malignant behavior. In the present study, the molecules responsible for GC cell-platelet interactions were examined and their therapeutic application in inhibiting the peritoneal dissemination of GC was investigated. First, the inhibitory effects of various candidate surface molecules were investigated on platelets and GC cells, such as C-type lectin-like receptor 2 (CLEC-2), glycoprotein VI (GPVI) and integrin αIIbβ3, in the platelet-induced enhancement of GC cell malignant potential. Second, the therapeutic effects of molecules responsible for the development and progression of GC were investigated in a mouse model of peritoneal dissemination. Platelet-induced enhancement of the migratory ability of GC cells was markedly inhibited by an anti-GPVI antibody and inhibitor of galectin-3, a GPVI ligand. However, neither the CLEC-2 inhibitor nor the integrin-blocking peptide significantly suppressed this enhanced migratory ability. In experiments using mouse GC cells and platelets, the migratory and invasive abilities enhanced by platelets were significantly suppressed by the anti-GPVI antibody and galectin-3 inhibitor. Furthermore, in vivo analyses demonstrated that the platelet-induced enhancement of peritoneal dissemination was significantly suppressed by the coadministration of anti-GPVI antibody and galectin-3 inhibitor, and was nearly eliminated by the combined treatment. The inhibition of adhesion resulting from GPVI-galectin-3 interaction may be a promising therapeutic strategy for preventing peritoneal dissemination in patients with GC.

Abstract
An 81-year-old man with advanced esophagogastric junction cancer with paraaortic lymph node metastasis was treated with S-1 plus oxaliplatin and nivolumab combination chemotherapy. Subsequently, conversion surgery was performed, and the patient was discharged without postoperative complications. Two months after discharge, the patient developed fever, fatigue, and anorexia. Intravenous antibiotic therapy was started; however, the symptoms did not improve. Urine biochemical tests revealed significantly elevated N-acetyl-β-D-glucosaminidase and β-microglobulin levels, and acute interstitial nephritis was suspected. Steroid therapy was initiated, and the patient's symptoms improved. A renal biopsy performed at the same time the nivolumab treatment was initiated led to the diagnosis of immune-related interstitial nephritis, a probable adverse event of the treatment. Although immune-related adverse events associated with immune checkpoint inhibitors are typically colitis, interstitial pneumonia, and endocrine disturbances, we observed severe interstitial nephritis in the patient. Clinicians should also consider the possible occurrence of immune-related adverse events >2 months after administering treatment.

Abstract
BACKGROUND/AIM We investigated the postoperative treatment status for diabetes mellitus and perioperative HbA1c levels in patients with diabetes mellitus and examined the effects of clinical factors on the remission of diabetes mellitus. PATIENTS AND METHODS In this study, 126 patients with gastric cancer were considered to have diabetes mellitus preoperatively, of whom 79 were treated with oral antidiabetic drugs and/or insulin treatment. We compared diabetic treatment status and HbA1c values between the preoperative and postoperative periods in patients who underwent gastrectomy and examined the effects of clinical factors on improving diabetes mellitus. RESULTS Of the 79 patients treated preoperatively for diabetes mellitus, 34 (43%) discontinued all medications for diabetes mellitus and for 37 (47%) the therapeutic dose was reduced or switched from insulin to oral antidiabetic drugs. Total gastrectomy was an independent factor for remission of antidiabetic treatments after gastrectomy. Concerning HbA1c levels, only the absence of preoperative insulin use was an independent factor for improvement. However, reconstruction was not a significantly correlated factor for the improvement of postoperative HbA1c levels and reduction of antidiabetic medications after distal gastrectomy. CONCLUSION Almost all patients discontinued or had their dose of antidiabetic medications reduced after gastrectomy in clinical practice, and special attention should be paid in the management methods for diabetes mellitus in patients who underwent total gastrectomy for gastric cancer.

Abstract
BACKGROUND The trans-hiatal lower esophagectomy is considered less invasive than the trans-thoracic esophagectomy for resection of esophagogastric junction (EGJ) cancer. However, the optimal procedure remains controversial and should be determined while considering both oncological and safety aspects. METHODS This retrospective study comprised 124 patients that underwent curative resection for EGJ cancer. The study analysis included 93 patients with tumor centers located within 2 cm of the EGJ. Clinicopathological findings and surgical outcomes were compared between patients treated using trans-hiatal and trans-thoracic approaches. RESULTS Sixty-three patients underwent lower esophagectomy using the trans-hiatal approach (TH-G). The remaining 30 patients underwent esophagectomy using the trans-thoracic approach (TT-E). The TH-G group were older, had a lower prevalence of lymphatic spread, shorter length of esophageal invasion, and shorter operative duration compared to the TT-E group. Although no significant differences in the frequency of postoperative complications, a higher proportion of patients in the TH-G group developed anastomotic leakage (16% vs. 7%, p = 0.33). Univariate and multivariate analyses demonstrated that cardiac comorbidity was an independent risk factor for anastomotic leakage (odds ratio, 5.24; 95% CI, 1.06-25.9; P < 0.05) in TH-G group. Further examination revealed that preoperative cardiothoracic ratio (CTR) with 50% or greater could be surrogate marker as risk factor for anastomotic leakage in TH-G group (35% vs. 7.5%, p < 0.05). CONCLUSIONS The trans-hiatal approach can be used for resection of EGJ cancer. However, special attention should be paid to the prevention of anastomotic leakage in patients with cardiac comorbidities or a large preoperative CTR.

Abstract
BACKGROUND/AIM Recent studies have reported that nicotinamide adenine dinucleotide phosphate oxidases (NOXs) are expressed in various cancers and play important roles in tumor progression. However, no studies have examined the expression and role of NOX2 in colon cancer. The aim of this study is to investigate the pathophysiological roles of NOX2 in colon cancer patients and cell lines. PATIENTS AND METHODS One-hundred and sixteen primary colon cancer samples of patients who underwent radical resection for locally advanced colon cancer were used for immunohistochemistry of NOX2 protein. The relationship between NOX2 expression and clinicopathological factors was assessed and the prognostic significance of NOX2 expression was evaluated in colon cancer patients. NOX2 siRNA transfection experiments were performed using two colon cancer cell lines (HCT116 and RKO) to analyze the impact of NOX2 expression on cellular physiological functions. RESULTS The expression of NOX2 protein in noncancerous tissue was scarcely observed, and 45 samples (38.8%) showed positively stained NOX2 expression in cancer tissue. There were no clinicopathological factors significantly associated with NOX2 expression. The 5-year recurrence-free survival rate of the NOX2 positive group was significantly lower than that of the NOX2 negative group (61.1% vs. 79.3%, p=0.029). NOX2 depletion significantly inhibited cell proliferation with G1 arrest, and motility in the two cell lines. CONCLUSION NOX2 expression level has a close association with the prognosis of colon cancer patients and physiological functions of colon cancer cells. NOX2 may be a useful prognostic biomarker for colon cancer patients.

Abstract
BACKGROUND Rikkunshito (TJ-43) relieves gastrointestinal disturbance by increases in the levels of acylated ghrelin.
AIM To investigate the effects of TJ-43 in patients undergoing pancreatic surgery.
METHODS Forty-one patients undergoing pylorus-preserving pancreaticoduodenectomy (PpPD) were divided into two groups; patients took daily doses of TJ-43 after surgery or after postoperative day (POD) 21. The plasma levels of acylated and desacylated ghrelin, cholecystokinin (CCK), peptide YY (PYY), gastric inhibitory peptide (GIP), and active glucagon-like peptide (GLP)-1 were evaluated. Oral calorie intake was assessed at POD 21 in both groups. The primary endpoint of this study was the total food intake after PpPD.
RESULTS The levels of acylated ghrelin were significantly greater in patients treated with TJ-43 than those in patients without TJ-43 administration at POD 21, and oral intake was significantly increased in patients treated with TJ-43. The CCK and PYY levels were significantly greater in patients treated with TJ-43 than those in patients without TJ-43 treatment. Furthermore, the GIP and active GLP-1 levels increased and values at POD 21 were significantly greater in patients treated with TJ-43 than those in patients without TJ-43 administration. Insulin secretion tended to increase in patients treated with TJ-43.
CONCLUSION TJ-43 may have advantages for oral food intake in patients in the early phase after pancreatic surgery. Further investigation is needed to clarify the effects of TJ-43 on incretin hormones.

Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
BACKGROUND/AIM Although cholesterol is an important indicator of nutritional status, it is also involved in cancer progression. In this study, we investigated the clinical significance of the dynamics of perioperative total cholesterol (T-Cho) levels in patients with gastric cancer (GC). PATIENTS AND METHODS A total of 212 patients with pathological stage II/III disease who underwent gastrectomy between 2004 and 2020 were enrolled in this retrospective study. The preoperative and postoperative serum T-Cho levels were measured in these patients. RESULTS Increased serum T-Cho levels were significantly correlated with low preoperative serum albumin levels (p<0.001). Patients with increased serum T-Cho levels after surgery had significantly lower overall and recurrence-free survival rates (p=0.030 and p=0.013, respectively; log-rank test). Cox proportional hazards model revealed that increased serum T-Cho levels (p=0.040), advanced pathological stage (p<0.001), and the provision of adjuvant chemotherapy (p=0.006) were independent prognostic factors for recurrence-free survival in patients with GC. CONCLUSION Increased serum T-Cho levels after gastrectomy may be an independent prognostic factor in patients with GC.

Abstract
INTRODUCTION Regorafenib is a multi-kinase inhibitor approved for patients with metastatic colorectal cancer (mCRC) who were previously treated with standard therapies. A few reports showed the impact of KRAS mutation on therapeutic efficacy of regorafenib. Only one study reported poor prognoses for patients treated with regorafenib who had large amounts of circulating cell-free DNA (cfDNA). In the present study, we evaluated the impact of KRAS mutations in tissue or plasma and amounts of cfDNA on prognoses of mCRC patients treated with regorafenib. METHOD This is a biomarker investigation of the RECC study, which evaluated efficacy of regorafenib dose-escalation therapy. Plasma samples were obtained just before initiation of treatment with regorafenib. KRAS mutations were evaluated using tissue and plasma samples. cfDNA was extracted from plasma samples and quantified. RESULTS Forty-five patients were enrolled in this biomarker study. Median progression-free survival (PFS) and overall survival (OS) of patients without KRAS mutations in tissues were 1.9 months (95% confidence interval [CI] 1.7-2.0) and 8.9 months (95% CI: 6.5-11.2), and those of patients with KRAS mutations were 1.4 months (95% CI: 1.3-1.5) and 6.8 months (95% CI: 5.0-8.5). Median PFS and OS of patients with plasma KRAS mutations were 1.9 months (95% CI: 1.8-1.9) and 7.0 months (95% CI: 5.3-8.7), respectively. Median PFS and OS of patients without plasma KRAS mutations were 1.7 months (95% CI: 1.1-2.3) and 8.9 months (95% CI: 6.7-11.2), respectively. Prior to administration of regorafenib, KRAS mutations were detected in 6 of 16 (37.5%) patients who had no tissue KRAS mutations. Median OS of patients with high cfDNA concentration (>median) was significantly poorer than that of patients with low cfDNA. CONCLUSION KRAS mutations in the tissue or plasma have no impact on efficacy of regorafenib. KRAS emerging mutations were observed in quite a few patients. Large amounts of cfDNA may indicate poorer prognoses for patients receiving late-line regorafenib chemotherapy.

Abstract
A 69-year-old female patient visited the previous hospital with anorexia and vomiting. She had weight loss and emaciation and was admitted to the hospital with a duodenal stenosis diagnosis due to superior mesenteric artery syndrome by computed tomography (CT). Conservative treatment with nutritional therapy was performed, but with no improvement;thus, the patient was referred to our hospital. We re-examined the patient to determine the cause of her disease. CT and magnetic resonance imaging findings revealed peritoneal thickening of the pelvic floor, suggesting malignant disease such as peritoneal dissemination. Therefore, we performed diagnostic laparoscopy and harvested peritoneal tissue. She was diagnosed with primary peritoneal carcinoma by histopathological examination and immunohistochemical staining techniques. Thereafter, she underwent chemotherapy for primary peritoneal cancer at the gynecology department of our hospital but died of the primary disease. Primary peritoneal cancer is frequently diagnosed by abdominal distention and abdominal pain due to ascites accumulation. We report this case because of the rarity of primary peritoneal cancer triggered by duodenal stricture.

Abstract
This study aimed to investigate the therapeutic effects of recombinant human thrombomodulin (rhTM) on acute lung injury (ALI) caused by sepsis in rats. Rats that underwent cecal ligation and puncture (CLP) were treated with or without rhTM, and then mortality was analyzed. In another set of experiments, ALI was assessed. Furthermore, microthrombosis in the lungs was investigated by immunohistochemistry. Moreover, plasma inflammatory and anti-inflammatory cytokines, such as TNF-α, high-mobility group box chromosomal protein 1 (HMGB-1), and IL-10, were evaluated by ELISA. Production of TNF-α and HMGB-1 by isolated tissue macrophages (Mφs) was assessed in vitro. Mortality after CLP was significantly improved by rhTM treatment. In addition, rhTM treatment improved the wet/dry weight ratio of the lungs, the pulmonary microvascular permeability, and the lung injury scores in animals that underwent CLP. Microthrombosis was detected in the lungs after CLP. These pathophysiological changes were blunted by rhTM treatment. Increased plasma TNF-α and HMGB-1 levels were blunted by rhTM treatment; however, the anti-inflammatory cytokine IL-10 was significantly greater in the rhTM(+) group than in the rhTM(-) group. Increased TNF-α and HMGB-1 production by the tissue Mφs stimulated with LPS were significantly blunted by rhTM treatment in vitro, but the production of IL-10 by the tissue Mφs was not changed in the cells incubated with rhTM. Overall, rhTM improved the mortality caused by septic peritonitis. The possible mechanisms are most likely anti-inflammatory and anticoagulant effects, which lead to the prevention of ALI.

Abstract
We divided the patients with biliary tract cancer who underwent pancreaticoduodenectomy(PD)at our hospital into the 5-year recurrence-free and recurrence groups and investigated the prognostic factors. Additionally, we investigated the efficacy of adjuvant chemotherapy in patients with and without lymph node (LN) metastasis. There was no significant difference between the two groups for patient characteristics and perioperative factors. However, patients with LN metastasis tended to have a higher recurrence rate. For patients without LN metastasis, the median overall survival(OS)was not significantly different between the patients who received and did not receive adjuvant chemotherapy. For patients with LN metastasis, although it was not significantly different(p=0.234), the OS of patients who received adjuvant therapy was more than 3 times than that of patients who did not(58.6 months and 18.4 months, respectively). For patients with biliary tract cancer who underwent PD, positive LN metastasis may be a poor prognostic factor, and adjuvant therapy may possibly improve prognosis.

Abstract
Background Generally, a large tumor size of hepatocellular carcinoma (HCC) is associated with poor visibility and uncertainty in the surgical field which results in increased surgical difficulty as well as unfavorable postoperative outcomes. We performed intended preoperative trans-arterial embolization (TAE) in patients with a large HCC. In this study, we investigated the oncological significance of intended preoperative TAE for a large HCC, using a comparison between patients with and without TAE, and detailed analyses for pre- and post-TAE status. Methods A total of 411 patients who underwent hepatectomy for primary HCC at the University of Yamanashi Hospital between January 2007 and December 2018 were included in this study. The patients were divided into two groups: patients with larger HCCs (≥50 mm, n=51) and those with smaller HCC (<50 mm, n=360) according to the size of their HCCs. Comparison of clinicopathological features between these groups and clinical outcomes between the TAE and non-TAE groups were compared. In addition, a detailed analysis of each case in the TAE group was conducted, comparing clinicopathological factors between pre- and post-TAE status. Results The clinical unfavorable short- and long-term outcomes of patients with large HCCs (≥50 mm) were revealed compared to those with small HCCs (<50 mm). The prognostic analyses showed that a large tumor size and increased tumor markers, multiple tumor numbers, and others were adverse prognostic factors, and vascular invasions and residual tumors were included in the multivariate analysis. Further detailed analyses revealed that the average rates of change in tumor size and tumor shrinkage after TAE were − 48.6±35.6 mm and − 30.7±17.0%, respectively. Pathological high necrotic changes in the tumor, after multiple-times TAE aiming to a better effect, were related to a better prognosis in patients with large HCC. Poor prognostic factors became less common in patients who underwent intended preoperative TAE, and these patients had better prognoses. Conclusions The large tumor size of HCC is associated with unfavorable outcomes; the intended preoperative TAE for large HCC patients performed multiple times aiming to affect the tumor as much as possible might improve their prognoses.

Abstract
The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present images of the second touchdown site, finding that ejecta from the impact crater was present at the sample location. Surface pebbles at both landing sites show morphological variations ranging from rugged to smooth, similar to Ryugu's boulders, and shapes from quasi-spherical to flattened. The samples were returned to Earth on 6 December 2020. We describe the morphology of >5 grams of returned pebbles and sand. Their diverse color, shape, and structure are consistent with the observed materials of Ryugu; we conclude that they are a representative sample of the asteroid.

Abstract
Background Duchenne muscular dystrophy (DMD) is an X-linked inherited myopathy that causes progressive skeletal and cardiac muscle disease. Heart lesions were described in the earliest DMD reports, and cardiomyopathy is now the leading cause of death. However, diagnostics and treatment for cardiomyopathy have lagged behind those for appendicular and respiratory skeletal muscle disease. Most animal model studies have been done in the mdx mouse, which has a relatively mild form of cardiomyopathy. Dogs with the genetically homologous condition, Golden Retriever muscular dystrophy (GRMD), develop progressive cardiomyopathy analogous to that seen in DMD. Previous descriptive studies of GRMD cardiomyopathy have mostly been limited to selective sampling of the hearts from young dogs. Methods and Results We systematically assessed cardiac lesions in 31 GRMD and carrier dogs aged 3 to 76 months and a separate cohort of 2–10-year-old normal hounds. Both semi-quantitative lesion scoring and quantitation of the cross-sectional area of fibrosis distinguished dogs with GRMD disease from normal dogs. The carriers generally had intermediate involvement but had even greater fibrosis than GRMD dogs. Fatty infiltration was the most prominent feature in some older GRMD dogs. Vascular hypertrophy was increased in GRMD dogs and correlated positively with lesion severity. Purkinje fiber vacuolation was also increased but did not correlate with lesion severity. Histopathologic changes correlated with late gadolinium enhancement on cardiac MRI. Conclusion These features are generally compatible with those of DMD and further validate GRMD as a useful model to study cardiomyopathy pathogenesis and treatment. Additionally, the nature of some degenerative lesions suggests that functional hypoxia or non-thrombotic ischemia may contribute to disease progression.

Abstract
Diffuse‑type gastric cancer, also known as scirrhous gastric cancer, is characterized by a larger number of stromal cells, referred to as cancer‑associated fibroblasts (CAFs), than the number of cancer cells in the tissue. The present study focused on CAFs in gastric cancer and examined their potential as a blood biomarker. A total of 46 and 84 patients with gastric cancer were respectively included in a development and an independent validation cohort to assess the clinicopathological characteristics of plasma podoplanin (PDPN) levels. The prognostic impact of plasma PDPN was also investigated in the validation cohort. The cut‑off value of the plasma‑PDPN concentration was set to the median plasma PDPN concentration in the development cohort that was then divided into the high‑PDPN and low‑PDPN groups. The high‑PDPN group tended to have more diffuse‑type disease (P=0.079), which was further confirmed through logistic regression analysis (P=0.008). Kaplan‑Meier survival estimates indicated that the recurrence‑free survival rate was significantly lower in the high‑PDPN group (P=0.029). In conclusion, plasma soluble PDPN was demonstrated to be a marker for diffuse gastric cancer and may reflect the prognosis of this disease.

Abstract
As the elderly population increases, the number of patients with gastric cancer has also been increasing. Elderly people have various preoperative problems such as malnutrition, high frequency of comorbidities, decreased performance status, and dementia. Furthermore, when surgery is performed, high postoperative complication rates and death from other diseases are also concerns. The goal of surgery in the elderly is that short-term outcomes are comparable to those in nonelderly, and long-term outcomes reach life expectancy. Perioperative problems in the elderly include: (1) Poor perioperative nutritional status; (2) Postoperative pneumonia; and (3) Psychological problems (dementia and postoperative delirium). Malnutrition in the elderly has been reported to be associated with increased postoperative complications and dementia, pointing out the importance of nutritional management. In addition, multidisciplinary team efforts, including perioperative respiratory rehabilitation, preoperative oral care, and early postoperative mobilization programs, are effective in preventing postoperative pneumonia. Furthermore, there are many reports on the usefulness of laparoscopic surgery for the elderly, and we considered that minimally invasive surgery would be the optimal treatment after assessing preoperative risk.

Abstract
OBJECTIVES The aim was to evaluate the relationship between cytoglobin (Cygb) expression and both clinicopathologic factors and prognosis in patients with pancreatic ductal adenocarcinoma (PDAC). METHODS Seventy-five patients with PDAC who underwent pancreatectomy between 2009 and 2014 at our department were included. Diagnosis was based on World Health Organization standards, with staging by TNM classification of Union for International Cancer Control. Expressions of Cygb, phosphoinositide-3 kinase, phosphorylated protein kinase B, interleukin-6, and vascular endothelial growth factor were evaluated by immunohistochemical staining of resected surgical specimens and densitometrical analysis. RESULTS Elevated expression of Cygb was found mainly in carcinoma cells of PDAC. Patients with low expression of Cygb showed significantly shorter disease-free survival and disease-specific survival than those with high expression. There was also a significant negative correlation between Cygb expression and the expressions of phosphoinositide 3-kinase, phosphorylated protein kinase B, interleukin-6, and vascular endothelial growth factor. In univariate analysis, Cygb expression, clinical stage, histologic tumor grade, lymphatic invasion, and vascular invasion were prognostic factors. In multivariate analysis, Cygb expression and the clinical stage were independent prognostic factors. CONCLUSIONS Loss of Cygb may contribute to tumor recurrence and poor prognosis of PDAC by increases in angiogenic factor.

Abstract
NADPH oxidases (NOXs) are a family of transmembrane proteins that generate reactive oxygen species. It was previously reported that patients with colon cancer who had high NOX5 expression had poor prognosis. However, no studies have investigated the cellular functions of NOX5 in colon cancer. The present study aimed to clarify the relationship between NOX5 and cancer development using an in vitro model. Reverse transcription‑quantitative PCR was performed to determine the NOX5 expression levels of colon cancer cell lines. NOX5‑knockdown experiments were conducted, and the effect on cell proliferation, migration, and invasion were analyzed. In addition, mRNA microarray was conducted to assess changes in gene profile. NOX5 mRNA expression was high in HCT116 cells and moderate in SW48 cells. NOX5 knockdown significantly inhibited cell migration and invasion in both HCT116 and SW48 cells; however, NOX5 knockdown reduced cell proliferation in only HCT116 cells. mRNA microarrays revealed a strong relationship between NOX5 expression levels and integrin‑linked kinase signaling pathways. The NOX5 expression in colon cancer cells affected cancer progression, especially cell motility. NOX5 may be a novel therapeutic target for the future development of treatments for colon cancer.

Abstract
BACKGROUND Pancreatectomy is a highly invasive procedure with extensive intraoperative blood loss (IBL) and high risk of postoperative pancreatic fistula (POPF). We conducted an experimental and retrospective clinical study to determine whether the malignant behaviors of pancreatic cancer cells were enhanced by exposure to blood components in vitro and to evaluate the oncological significance of high IBL and POPF in pancreatic cancer. METHODS This study included 107 patients undergoing radical pancreatectomy in the University of Yamanashi Hospital between 2011 and 2017, classified into high (n = 29) and low (n = 78) IBL groups. In vitro experiments included functional analyses of Panc-1 pancreatic cancer and normal mesothelial cells exposed to patient blood components, and clinical data were used to assess the contribution of IBL and POPF to patient outcomes. RESULTS The migration (p = 0.007), invasion (p < 0.001), and proliferation (p < 0.01) of Panc-1 cells were enhanced with platelet coculture. The ability of Panc-1 cells to adhere mesothelial cells was enhanced by plasma coincubation, especially in the presence of inflammation (p < 0.001). High IBL was associated with worse overall survival (p = 0.007) and increased locoregional recurrence (p = 0.003) in patients. POPF enhanced the negative prognostic significance of high IBL (p < 0.001 for overall survival, p = 0.001 for locoregional recurrence), indicating the oncological negative effects of high IBL and POPF. CONCLUSIONS Blood components, especially platelets, and inflammation enhance the malignant behaviors of pancreatic cancer cells, potentially contributing to poor prognosis for pancreatic cancer patients.

Abstract
OBJECTIVES Nutritional status significantly influences postoperative prognosis in gastrointestinal cancers. It has been evaluated using sarcopenia before treatments such as surgery and chemotherapy, despite constant changes in nutritional status. We consider that nutritional status at cancer recurrence is one of the important factors that affect treatment choice and intensity. This study evaluated the prognostic effects of improved postoperative nutritional status for people with colorectal cancer recurrence. METHODS We enrolled 209 participants with pathologically confirmed stage II or III colorectal cancer who underwent radical resection. Sarcopenia was diagnosed using the psoas muscle index obtained from analysis of three-dimensional computed tomographic images. We adopted the cutoff value that was proposed by Hamaguchi et al. (psoas muscle index < 6.36 cm2/m2 for men and < 3.92 cm2/m2 for women). Evaluation was performed before surgery and at the time of recurrence. Participants with preoperative sarcopenia who relapsed were divided into two groups at the time of recurrence: sarcopenia continuation and sarcopenia improvement. We compared the prognosis of the two groups and examined the effect of postoperative nutritional improvement. RESULTS Among the 209 participants, 81 (38.8%) had preoperative sarcopenia; this group had significantly lower overall survival than those without sarcopenia (P = 0.028). Colorectal cancer recurred in 48 participants. Of those 46, sarcopenia was evaluated at the time of recurrence; 19 of those 46 had preoperative sarcopenia. Preoperative sarcopenia did not affect the cancer recurrence ratio (sarcopenia, 23.5%; non-sarcopenia, 21.3%; P = 0.893). The sarcopenia-improvement group had higher overall survival than the sarcopenia-continuation group (P = 0.042). CONCLUSIONS Among participants with preoperative sarcopenia, the prognosis at the time of recurrence improved for the sarcopenia-improvement group compared to the sarcopenia-continuation group. In people with colorectal cancer and sarcopenia, nutritional management is important not only before but also after surgery.

Abstract
Background Traditionally, the surgery for simultaneous double cancer of the stomach and colon required a large incision to the upper and lower region of the abdomen. In this case, an artificial blood vessel was located under the skin after revascularization. Considering ischemia due to graft compression by incision retractor during laparotomy, this was difficult to do. This is a report on laparoscopic surgery for simultaneous double cancer of the stomach and colon after revascularization. Case presentation A 69-year-old man had early gastric cancer and advanced sigmoid colon cancer. He had suffered from thromboangitis obliterans and has undergone revascularization many times due to poor blood flow in his lower limbs. He had had some artificial blood vessels inserted under the skin, confirmed by blood vessel construction image by preoperative computed tomography (CT). There was a bypass vessel from the left axillary artery to the left femoral artery under the skin of the left thoracoabdominal. In addition, there were two bypass vessels from the left external iliac artery to the right femoral artery under the skin of the lower abdomen. One of the two bypasses was occluded. In the blood flow to the intestinal tract, the inferior mesenteric artery was already occluded. Peripheral blood flow in the common iliac artery depended on blood flow from the artificial blood vessel, and blood flow from the internal iliac artery to the rectum was poor. Laparoscopic Hartmann’s operation was performed for Stage II B (UICC 8th Edition) sigmoid colon cancer. Because the blood flow in the intestinal tract on the anal side was poor, we thought that anastomosis was at a high risk for leakage. Laparoscopic total gastrectomy was also performed simultaneously for two Stage I (UICC 8th edition) gastric cancers in the cardia and body. The location of the port site and stoma was carefully determined preoperatively to prevent damage and infection to the artificial blood vessels. Minimal invasive surgery was performed using laparoscopic surgery. Conclusions Laparoscopic surgery with small incisions is useful for patients with double cancer who need an approach to the upper and lower abdomen. Furthermore, laparoscopic surgery has less interference on graft in patients with artificial blood vessels under the skin by intraperitoneal approach.

Abstract
Biomarkers may be of value for the early detection of gastric cancer (GC) and the preoperative identification of tumor characteristics to guide treatment strategies. The present study analyzed the expression levels of phospholipids in plasma from patients with GC using liquid chromatography/electrospray ionization-mass spectrometry (LC/ESI-MS) to detect reliable biomarkers for GC. Furthermore, combining the results with a machine learning strategy, the present study attempted to establish a diagnostic system for GC. A total of 20 plasma samples from preoperative patients with GC and 16 plasma samples from tumor-free patients (controls) were selected from our biobank named ‘SHINGEN (Yamanashi Biobank of Gastroenterological Cancers)’, which includes a total of 1,592 plasma samples, and were analyzed by LC/ESI-MS. The obtained data were discriminated using a machine learning-based diagnostic algorithm, whose discriminant ability was confirmed through leave-one-out cross-validation. Using LC/ESI-MS, the levels of 236 lipid molecules were determined. Biomarker analysis revealed that a few lipids that were downregulated in the GC group could discriminate between the GC and control groups. Whole lipid composition analysis using partial least squares regression revealed good discrimination ability between the GC and control groups. Integrative analysis of all molecules using the aforementioned machine learning method exhibited a diagnostic accuracy of 94.4% (specificity, 93.8%; sensitivity, 95.0%). In conclusion, the outcomes of the present study suggested the potential future application of the aforementioned system in clinical settings. By accumulating more reliable data, the present system will be able to detect early-stage cancer and will be capable of predicting the efficacy of each therapeutic strategy.

Abstract
OBJECTIVES It has been reported that preoperative nutritional status in some gastrointestinal cancers has a significant effect on postoperative prognosis. However, there are few reports on esophageal cancer, especially for esophageal cancer patients who have undergone neoadjuvant therapy and surgery. Psoas muscle index (PMI) is widely known as an index for assessing preoperative nutritional status, and has recently been reported for its prognostic value in many malignancies. The aim of this study was to investigate and evaluate the clinical results in our hospital using the PMI method. METHODS We retrospectively investigated esophageal cancer in patients (clinical stage II or III) who underwent neoadjuvant therapy and surgical treatment (R0 cases) from January 2008 to December 2015. Applicable 63 cases were entered accordingly. In our hospital, nutritional supplements are used for nutritional management during preoperative adjuvant therapy, and these are administered to patients who have difficulty ingesting nutrition by feeding tube or total parenteral nutrition. The target value for nutritional supplement administration was 36 kcal/kg. Taking into account that chemotherapy for esophageal cancer was being performed using Harris-Benedict's basal energy expenditure (25 kcal/kg), we multiplied by 1.44 (active factor; 1.2, stress factor; 1.2) and set 36 kcal/kg as a guide. PMI was evaluated before neoadjuvant therapy and before surgery. We defined sarcopenia by PMI of the third lumbar vertebra (L3) by a computed tomography (CT) examination using 3-dimensional image analysis software, <6.36 for men and <3.92 for women, and investigated the effect of each on prognosis. RESULTS The prevalence of sarcopenia decreased from 74.6% (47 of 63) to 69.84% (44 of 63) during the pretherapeutic to preoperative period (P = 0.691), suggesting improved nutritional status. Regarding PMI divided by cutoff value for each sex (the cutoff value was the PMI mean value -2 SD [6.36 cm2 m2 for men and 3.92 cm2/m2 for women] of healthy individuals <50 y of age, which was reported as a standard for low skeletal muscle mass in Japanese individuals), there was an improvement observed in the preoperative compared to pretherapeutic period, but it was not obtained as a significant difference (pretherapeutic PMI; 0.87 ± 0.06 [mean ± SD], preoperative PMI; 0.89 ± 0.06 [mean ± SD], P = 0.18). In overall survival (OS) and disease-free survival (DFS), there was no significant difference in the short-term results with and without sarcopenia in the pretherapeutic group (both OS and DFS, P = 0.17). There was a significant difference with and without sarcopenia in the preoperative group in terms of OS and DFS (OS, P = 0.045; DFS, P = 0.043), which was short term due to nutritional intervention during preoperative adjuvant therapy. It was suggested that the results would be improved. CONCLUSIONS Improving nutritional status before surgery was shown to improve short-term prognosis in patients with esophageal cancer. It is hence suggested that it is important to maintain or improve nutritional status by intervention from the time of neoadjuvant therapy.

Abstract
BACKGROUND/AIM The high rate of recurrence and repetitive features of hepatocellular carcinoma (HCC) require specific treatment strategies. This study aimed to evaluate the long-term outcomes of recurrent HCC focusing on clinicopathological factors. PATIENTS AND METHODS A total of 104 patients who were treated with re-hepatectomy, radiofrequency ablation (RFA) or transcatheter arterial chemoembolization for recurrent HCC were analyzed. Post-recurrent prognoses were compared between each treatment group based on the presence of adverse prognostic factors (APFs) identified. RESULTS In the hepatectomy group, the prognosis of patients with APFs was significantly worse compared to those without APFs. By contrast, the survival rate of patients who underwent RFA was not significantly different from those with and without APFs. CONCLUSION Our results demonstrate the heterogeneity that exists in terms of the long-term survival of patients with recurrent HCC. The treatment strategy for recurrent HCC should be based on the assessment of presence of APFs to improve long-term prognosis.

Abstract
BACKGROUND/AIM This study examined the prognostic impact of the past history of breast cancer screening within the last 2 years (PH-BCS), for patients with triple negative breast cancer (TNBC), a subtype that carries extremely poor prognosis. PATIENTS AND METHODS Eighty-six consecutive cases with TNBC, who underwent surgery at our faculty from 2009 to 2015, were divided into two groups according to PH-BCS. Prognostic analyses for disease-free survival and overall survival between the two groups were performed. RESULTS The positive PH-BCS group (n=44) had a significantly better prognoses than the negative PH-BCS group (n=42) (p<0.001). No recurrent cases were observed in the positive PH-BCS group. In the negative PH-BCS group, tumor and node status and chemotherapy were indicated as significant prognostic factors, and further step-wise multivariate analysis revealed only node status as a significant prognostic factor. CONCLUSION Breast cancer screening at least every 2 years may improve the prognosis of TNBC.

Abstract
BACKGROUND/AIM Drains are frequently placed at the time of distal pancreatectomy (DP) to evacuate pancreatic juice and intra-abdominal exudate and obtain information on abdominal cavity status. However, the timing of drain removal remains debatable. Meanwhile, prolonged drain placement might increase the risk of postoperative pancreatic fistula (POPF), with a prevalence of 5-40%. Therefore, we examined the effect of removing the drain within postoperative day (POD) 3 on the risk of POPF development. PATIENTS AND METHODS A total of 108 consecutive patients who underwent DP between April 2015 and March 2020 were examined and divided into two groups according to the day of drain removal; hence, for some patients, the drain was removed on POD 1 (POD 1 group) and for others on POD 3 (POD 3 group). Furthermore, risk factors, including drain fluid amylase (DFA) levels, for developing POPF were investigated. RESULTS The overall rate of clinically relevant POPF was 4.6% and did not significantly differ between the POD 1 and POD 3 groups [4.5% and 4.9%, respectively (p=0.924)]. DFA levels on POD 1 did not significantly differ between patients with and without POPF. On POD 3 and POD 5, C-reactive protein (CRP) levels were significantly higher in patients with POPF than in those without (p=0.03 and p<0.001, respectively). CONCLUSION Early drain removal regardless of DFA level may reduce the risk of developing POPF. CRP measured on POD 3 and POD 5 appeared to be a useful predictor of clinically relevant POPF.

Abstract
BACKGROUND/AIM We aimed to evaluate the correlation between stroke volume variation (SVV) and intraoperative blood loss (IBL) in hepatocellular carcinoma (HCC) resection and examine the perioperative utility of SVV-based management. PATIENTS AND METHODS Ninety-five patients who underwent partial or sub-segmental hepatectomy for HCC between 2013 and 2019 at the University of Yamanashi Hospital were retrospectively analyzed. A correlation analysis between IBL and SVV was performed, and then all cases were divided into three groups: high, middle, and low-SVV groups. Perioperative short-term outcomes based on SVV groups were analyzed. RESULTS There was a weak but significant negative correlation between SVV and IBL (ρ=-0.372, p<0.001). Comparative analysis revealed that low-SVV was associated with a high incidence of postoperative complications and blood transfusion (p=0.018 and 0.037, respectively), and high-SVV was not related with postoperative complications. CONCLUSION SVV-based management is a significant and feasible strategy to achieve safe and exact surgical resection of HCC.

Abstract
PURPOSE The purpose of this study was to clarify the predictors of efficacy of nab-paclitaxel plus gemcitabine(GnP)for patients with recurrence after resection for adenocarcinoma of the pancreas. METHOD Patients who had received GnP at our hospital were divided into 2 groups; effective group and non-effective group and we compared them. In addition, we compared the therapeutic effect of patients between well-differentiated adenocarcinoma and moderately differentiated adenocarcinoma. Furthermore, we compared the efficacy depending on the time of recurrence. RESULTS In patients with well-differentiated adenocarcinoma, the disease control rate was 93.6% and progression free survival was 8.6 months, whereas those in patients with moderately differentiated adenocarcinoma were 57.1% and 4.4 months, respectively. Patients who recurred at 7 months or later, had a better therapeutic response than the patients who recurred within 6 months after surgery. CONCLUSIONS GnP may be effective in patients with well-differentiated adenocarcinoma and in patients who recurred at 7 months or later.

Abstract
50's man who have performed anterior pelvic exenteration with lateral lymph node dissection for rectal cancer with pT4bN0M0, pStage Ⅱc about 2 years ago, was admitted to our hospital for the treatment of intrapelvic recurrence of rectal cancer. No distant metastasis was found in the computed tomography examination but the tumor invaded the dorsal side of the pubis. Because radical excision was impossible with these findings, he received chemoradiotherapy(CRT). Post-CRT imaging showed that the tumor of intrapelvic recurrence region reduced the size, and invasion of pubis had disappeared and been markedly reduced. Thus, radical excision seemed possible at this point, and we decided to attempt operation after total 6 weeks of S-1(120 mg/day)regimen and radiation(40 Gy/20 Fr). We performed Miles' operation. The final pathological examination demonstrated that no viable tumor cells remained in the resected rectum specimen, confirming that a pathological complete response(pCR)had been achieved.

Abstract
Background Postoperative pancreatic fistula (POPF) is one of the most serious complications after pancreaticoduodenectomy (PD). Various factors have been reported as POPF risks, but the most serious of these is soft pancreas. To reduce POPF occurrences, many changes to the PD process have been proposed. This study evaluates short-term results of anastomosis technique for PD. Methods In total, 123 patients with soft pancreases who had undergone PD at Yamanashi University between January 2012 and August 2020 were retrospectively analyzed. We divided these patients into two groups depending on the time PD was performed: a conventional group (n = 67) and a modified group (n = 56). Results The rate of clinically relevant POPF was significantly lower in the modified group than that in the conventional group (5.4% vs 22.4%, p value < 0.001), with there being only one case of POPF in the modified group. There were no cases of POPF-related hemorrhaging in the modified group. On the third day after the operation, the amylase levels in the drainage fluid for the modified group became less than half (1696 vs 650 U/L). Multivariate analysis showed that the modified method was the independent predictors to prevent clinical POPF (p value = 0.002). Conclusions Our novel anastomosis technique for pancreatojejunostomy reduced POPF in PD, especially in cases where the patient had a soft pancreas.

Abstract
One of the most challenging issues among experts is how to improve motor skills that have already been highly trained. Recent studies have proposed importance of both genetic predisposition and accumulated amount of practice for standing at the top of fields of sports and performing arts. In contrast to the two factors, what is unexplored is how one practices impacts on experts' expertise. Here, we show that training of active somatosensory function (active haptic training) enhances precise force control in the keystrokes and somatosensory functions specifically of expert pianists, but not of untrained individuals. By contrast, training that merely repeats the task with provision of error feedback, which is a typical training method, failed to improve the force control in the experts, but not in the untrained. These findings provide evidence that the limit of highly trained motor skills could be overcome by optimizing training methods.

Abstract
Abstract
Background
The right ventricular (RV) function is a significant predictor of the prognosis and exercises tolerance in patients with left ventricular dysfunction. The previous study reported that RV late gadolinium enhancements (LGE) as assessed by cardiac magnetic resonance (CMR) imaging were present in 16% of pulmonary sarcoidosis. Although RV LGE is associated with a poor prognosis, a semi-quantitative assessment of RV LGE was not been established so far. Moreover, the frequency of RV dysfunction (RVD) in cardiac sarcoidosis (CS) and predictors of RVD are unclear.
Purpose
Our aim of this study is to establish RV LGE semi-quantitative scores and to clarify the rate and predictors of RVD in CS.
Methods
Forty-four consecutive patients with CS who underwent CMR imaging (median age, 63 [IQR 54–71] years old; 10 males) were studied. They were diagnosed as definitive based on the Heart Rhythm Society expert consensus statement. Two patients were excluded due to no long axial view. Thus, a total of 42 patients were included in this study. RV LGE was semi-quantitatively evaluated using the original score developed by ours. RV was classified into RV outflow tract (OT), basal, middle and apex. RVOT and apex are assigned 1 segment for each, and basal and middle are assigned 4 segments include anterior, septal, inferior and lateral (Figure1). In total, 10 segments were evaluated. RV LGE scores were analysed independently by the two operators. The RV ejection fraction was assessed in a long axial view without an RVOT (20 phases, 12 slices). We divided the cohort into the non-RVD group (RVEF ≥45%) and the RVD group (RVEF <45%) and compared the RV scores between the two groups.
Results
The RVD was present in 31% of the entire cohort. The presence of RV LGE was significantly higher in the RVD group than the non-RVD group (83% vs. 43%, p=0.037). RV LGE score in the RVD group was significantly higher than that in the non-RVD group (2.83±1.95 vs. 0.83±1.21, p=0.001). The septal lesions in basal and middle levels accounted for 54% in all segments. RVEF showed a significant inverse correlation with RV LGE score (r=−0.57, p<0.0001). In the ROC curve for RVD, the RV LGE score of more than 2 and equal could discriminate RVD from non-RVD with AUC of 0.813 (Sensitivity = 0.77, Specificity = 0.76, p=0.003).
Conclusion
RVD was observed in 31% of patients with definitive CS. The septal lesions were the most frequent in the RV LGE site, which suggests that the longitudinal abnormal motion of RV is a significant predictor of the RVD in patients with CS. RV LGE score is a valuable method to assess RVD.

Abstract
Background The number of elderly patients with gastric cancer has been increasing. Most elderly patients have associated reduced physiologic functions that can sometimes become an obstacle to safe surgical treatment. The National Clinical Database Risk Calculator, which based on a large Japanese surgical database, provides predicted mortality and morbidity in each case as the surgical-related risks. The purpose of this study was to investigate the clinical significance of the risk for operative mortality (NRC-mortality), as calculated by the National Clinical Database Risk Calculator, during long-term follow-up after gastrectomy for elderly patients with gastric cancer. Methods We enrolled 73 patients aged ≥ 80 years and underwent gastrectomy at our institution. Their surgical risk was evaluated based on the NRC-mortality. Several clinicopathologic factors, including NRC-mortality, were selected and analyzed as the possible prognostic factors for elderly patients who have undergone gastrectomy for gastric cancer. Statistical analysis was performed using the log-rank test and Cox proportional hazard model. Results NRC-mortality ranged from 0.5 to 10.6%, and the median value was 1.7%. Dividing the patients according to mortality, the overall survival was significantly worse in the high mortality group (≥ 1.7%, n = 38) than in the low mortality group (< 1.7%, n = 35), whereas disease-specific survival was not different between the two groups. In the Cox proportional hazard model, multivariate analysis revealed NRC-mortality, performance status, and surgical procedure as the independent prognostic factors for overall survival. For disease-specific survival, the independent prognostic factors were performance status and pathological stage but not NRC-mortality. Conclusion The NRC-mortality might be clinically useful for predicting both surgical mortality and overall survival after gastrectomy in elderly patients with gastric cancer.

Abstract
In this study, we aimed to analyse human cancer cell–platelet interactions in functional cell analyses and explore the molecular mechanisms behind tumour progression. Various functional analyses of gastric cancer (GC) cells were performed after direct/indirect co-incubation with platelets derived from GC patients. Further detailed expression and signalling analyses were performed after co-culture with direct and indirect GC cells–platelet contact. Malignant behaviours of cancer cells, such as proliferation, migration, invasion and adhesion, were significantly enhanced after direct co-incubation with platelets. Microarray analyses demonstrated changes in multiple genes, including epithelial–mesenchymal transition (EMT)-related genes. Among them, matrix metalloproteinase 9 was notably upregulated, which was validated by quantitative reverse transcription–polymerase chain reaction and western blot. Further, this change was only observed after direct co-incubation with platelets. This study demonstrated that platelets from GC patients promote malignant behaviours of GC cells through EMT-related signalling, especially by direct contact with tumour cells.

Is Intraluminal Washout Necessary for Patients with Sigmoid Colon Cancer to Eliminate Exfoliated Cancer Cells as in Patients with Rectal Cancer? A Pilot Study at a Single Institute.

Abstract
Objectives: Rectal stump washout has been widely performed to prevent the implantation of exfoliated cancer cells (ECCs) in patients with rectal cancer. However, it remains unclear whether intraluminal washout before transection is required in patients with sigmoid colon cancer. Therefore, this pilot study was conducted to elucidate the necessity of intraluminal washout for sigmoid colon cancer patients in comparison with rectal cancer patients by cytological assessments. Methods: A total of 16 patients with sigmoid colon cancer and 24 patients with rectal cancer who underwent sigmoidectomy or anterior resection with anastomosis using double-stapling technique were enrolled. A transanal washout sample was collected before washout and after irrigation with 500 and 1,000 mL of saline. Cytological assessments were conducted according to the Papanicolaou classification, and class IV and V cells were defined as malignant. Results: Before washout, exfoliated cancer cells were found in 15 of 24 (62.5%) patients with rectal cancer and in 1 of 16 (6.2%) patients with sigmoid colon cancer (p < 0.001). Distal-free margin from the tumor was significantly shorter in patients with cancer cells (p = 0.002), and the length of the distal-free margin was significantly associated with the tumor location. After irrigation with 500 and 1,000 mL of saline, no cancer cell was found in all patients with sigmoid colon cancer, whereas ECCs were still found in five patients with rectal cancer (20.8%). Conclusions: Intraluminal washout with 1,000 mL may be sufficient for sigmoid colon cancer patients with longer distal-free margin. A large-scale, randomized controlled study is necessary to confirm these results.

Abstract
Human alcoholic hepatitis (AH) carries a high mortality rate. AH is an acute-on-chronic form of liver injury characterized by hepatic steatosis, ballooned hepatocytes, neutrophil infiltration, and pericellular fibrosis. We aimed to study the pathogenesis of AH in an animal model which combines chronic hepatic fibrosis with intragastric alcohol administration. Adult male C57BL6/J mice were treated with CCl4 (0.2 ml/kg, 2×weekly by intraperitoneal injections for 6 weeks) to induce chronic liver fibrosis. Then, ethyl alcohol (up to 25 g/kg/day for 3 weeks) was administered continuously to mice via a gastric feeding tube, with or without one-half dose of CCl4. Liver and serum markers and liver transcriptome were evaluated to characterize acute-on-chronic-alcoholic liver disease in our model. CCl4 or alcohol treatment alone induced liver fibrosis or steatohepatitis, respectively, findings that were consistent with expected pathology. Combined treatment resulted in a marked exacerbation of liver injury, as evident by the development of inflammation, steatosis, and pericellular fibrosis, pathological features of human AH. E. coli and Candida were also detected in livers of mice cotreated with CCl4 and alcohol, indicating pathogen translocation from gut to liver, similar to human AH. Importantly, liver transcriptomic changes specific to combined treatment group demonstrated close concordance with pathways perturbed in patients with severe AH. Overall, mice treated with CCl4 and alcohol displayed key molecular and pathological characteristics of human AH-pericellular fibrosis, increased hepatic bacterial load, and dysregulation of the same molecular pathways. This model may be useful for developing therapeutics for AH.

Abstract
BACKGROUND Phyllodes tumor (PT) is a rare tumor of the breast, which may occur during pregnancy or lactation. Several studies have reviewed and discussed PT occurring in pregnancy, gathering up to 14 patients. We performed a thorough systematic review of the literature in an attempt to find all reported cases, and identify their common characteristics. METHODS We searched Google scholar, PubMed, Ovid Medline, Scopus and ClinicalTrials.gov with several relevant combinations of keywords, looking for texts or abstracts without any date or language limitations, but using only English keywords. The existing literature only consisted of case reports and series; therefore any paper including one or several cases of PT presenting during pregnancy or breastfeeding was recognized as eligible. Articles with vague description of the tumor which made the diagnosis uncertain, and those lacking data about the tumor and management data were excluded. We contacted authors for more details in cases with incomplete information. RESULTS After excluding those with very deficient data, we included 37 studies, counting 43 cases. The mean age of the patients was 31 years (21-43 years). Some features were different from usual PT: bilaterality (16.2%), large size (14.2 ± 8.6 cm), rapid enlargement (79.5%), and rate of malignancy (60.5%). CONCLUSION Our findings show high rates of bilaterality, large size, rapid growth, and malignant pathology in the reported gestational PTs.

Abstract
Cholestatic liver injury leads to liver dysfunction. The available evidence suggests that platelets can either promote or reduce liver injury and fibrosis. This study focused on the functions of the C-type lectin-like receptor 2 (CLEC-2), a new special platelet receptor that binds with podoplanin-activating platelets. The role of CLEC-2 and podoplanin in cholestatic liver injury was investigated. Mice were injected intraperitoneally with weekly doses of anti-CLEC-2 antibody (2A2B10) to achieve effective CLEC-2 inhibition in their platelets. Next, left and middle hepatic bile duct ligation (BDL) procedures were performed, and mice were euthanized 1 week later (2A2B10-BDL group). In addition, mice were prepared for control groups, and relevant histological and laboratory variables were compared among these groups. The inhibition of CLEC-2 resulted in increasing hepatocellular necrosis, hepatic inflammation, and liver fibrosis. In addition, podoplanin was strongly expressed in hepatic sinusoidal endothelial cells in BDL-treated mice. Moreover, in 2A2B10-BDL mice, total plasma bile acid levels were significantly increased. In summary, podoplanin is expressed on hepatic sinusoidal endothelial cells upon BDL. Platelets bind with podoplanin via CLEC-2 and become activated. As a result, the total bile acid pool is decreased. Therefore, the CLEC-2-podoplanin interaction promotes liver protection and inhibits liver fibrosis after cholestatic liver injury.

Abstract
BACKGROUND/AIM Elevated neutrophil-lymphocyte ratio (NLR) has been reported to be a poor prognostic factor in patients with colorectal cancer (CRC). However, no studies have focused on the dynamic change of preoperative NLR (pre-NLR) in CRC patients. We investigated the prognostic value of the change in NLR (ΔNLR) in CRC patients before and after surgery. PATIENTS AND METHODS We retrospectively analyzed the data from 307 patients with stage II or III CRC. We compared the clinicopathological factors, OS, and DFS among the various NLR factors. RESULTS The 5-year OS rate of the high ΔNLR group was significantly lower than that of the low ΔNLR group (p<0.01). The 5-year DFS rates of the high ΔNLR groups were worse than those in the low ΔNLR groups. In the multivariate analysis, ΔNLR was an independent prognostic factor (p=0.011). CONCLUSION Decreasing post-NLR was related to better OS and DFS even in high pre-NLR patients with CRC.
