Abstract
BACKGROUND Heineke-Mikulicz (HM) strictureplasty is commonly used to treat short stenoses in Crohn's disease. However, the degree to which intestinal motility is maintained remains unclear. We compared the peristalsis and transport capacity of the sutured intestines with HM configuration and transverse (TS) and longitudinal (LS) incisions. METHODS The intestinal diameter, intraluminal pressure, and bead transit time of each sutured group were compared with that of the non-treatment (NT) group in the isolated proximal colon of rats. Propulsive contractions were induced using hydroxy-?-sanshool (HAS), a constituent of Japanese pepper. RESULTS There was no change in the intestinal diameter between HM, TS, and NT groups ; however, it was significantly narrowed at the suture site and its distal side in the LS group. After HAS administration, the intestinal diameter at the suture site in the HM group was higher than that in the LS group. The intraluminal pressure was higher and the transit time was shorter in the HM group compared to those in the LS group. CONCLUSIONS The HM configuration, which widens the incision site and distal diameter and shortens the cut surface of the circular muscle in the longitudinal direction, may help maintain basal and HAS-induced intestinal peristalsis and motility.

Abstract
INTRODUCTION Robot-assisted radical prostatectomy (RARP) is nowadays being performed worldwide, and inguinal hernia (IH) continues to be a common complication of radical prostatectomy. Laparoscopic repair of IH is often difficult via internal dissection because of adhesion of the preperitoneal cavity. This study aimed to categorize the intraoperative condition of, and devise a strategy for, IH after RARP. METHODS Of 577 patients who underwent RARP, 18 developed IH. These 18 patients then underwent laparoscopic IH repair using the transabdominal preperitoneal approach (TAPP) or modified intraperitoneal onlay mesh repair (mIPOM). Internal dissection was categorized into two groups according to the appearance of Cooper's ligament (exposed or not exposed). RESULTS After RARP, four patients had exposure of Cooper's ligament while 14 patients showed no exposure. Both patients in the exposed group underwent TAPP and all patients in the not-exposed group underwent mIPOM. There was no significant difference between normal TAPP and RARP regarding operative factors, and IH recurrence was not observed. CONCLUSION Laparoscopic repair of IH after RARP is rendered safe and efficient by using our categorization based on the exposure of Cooper's ligament and extension of preperitoneal space.

Abstract
Background: Anastomotic leakage (AL) after colorectal surgery is associated with insufficient vascular perfusion of the anastomotic ends. This study aimed to evaluate the effect of high vs. low ligation of the ileocolic artery and inferior mesenteric artery, respectively, on the vascular perfusion of the bowel stumps during ileocecal resection (ICR) and anterior rectal resection (AR). Methods: We retrospectively evaluated patients who underwent ICR or AR between 2016 and 2020. Real-time indocyanine green fluorescence angiography was performed to measure the fluorescence time (FT) as a marker of the blood flow in the proximal and distal stumps before anastomosis. Results: Thirty-four patients with lower right-sided colon cancer underwent laparoscopic ICR. Forty-one patients with rectosigmoid colon or rectal cancer underwent robotic high AR (HAR) (n = 8), robotic low AR (LAR) (n = 6), laparoscopic HAR (n = 8), or laparoscopic LAR (n = 19). The FT was similar in the ileal and ascending colon stumps (p = 1.000) and did not differ significantly between high vs. low ligation of the ileocolic artery (p = 0.934). The FT was similar in the sigmoid colon and rectal stumps (p = 0.642), but high inferior mesenteric artery ligation significantly prolonged FT in the sigmoid colon during AR compared with low ligation (p = 0.004), indicating that the high ligation approach caused significant hypoperfusion compared with low ligation. The AL rate was similar after low vs. high ligation. Conclusions: Low vascular perfusion of the bowel stumps may not be an absolute risk factor for AL. High inferior mesenteric artery ligation could induce sigmoid colon stump hypoperfusion during anterior rectal resection.

Abstract
Stromal cell-derived factor-1 (SDF-1) expression is associated with cancer progression, as a biomarker of prognosis. We clarified the significance of SDF-1 expression on chemoradiotherapy (CRT) resistance and prognosis in advanced lower rectal cancer patients. We evaluated 98 patients with advanced lower rectal cancer who underwent preoperative CRT. All patients received 40 Gy of radiation therapy, with concurrent chemotherapy containing fluorinated pyrimidines, followed by surgical resection. SDF-1 expression in surgical specimens was examined by immunohistochemistry. We divided the patients into SDF-1-positive- (n = 52) and SDF-1-negative groups (n = 46) and compared the clinicopathological factors and survival rates. The SDF-1-positive group was more resistant to CRT than the SDF-1-negative group (non-responder rate, 63.5% vs. 47.8%, respectively ; p = 0.12). Overall survival (OS) in the SDF-1 positive group was significantly poorer vs. the SDF-1-negative group (5-year OS, 73.4% vs. 88.0%, respectively ; p = 0.02), and disease-free survival (DFS) was worse (5-year DFS, 61.0% vs. 74.1%, respectively ; p = 0.07). Multivariate analysis confirmed that SDF-1 expression was a significant independent prognostic predictor of OS (p = 0.04). SDF-1 expression after preoperative CRT is significantly associated with a poor prognosis in advanced lower rectal cancer patients and is a promising biomarker. J. Med. Invest. 68 : 309-314, August, 2021.

Abstract
Background : Surgical site infection (SSI) is an adverse event that places a major burden on patients and staff. In this study, we examined the occurrence of SSI and the characteristics of patients referred to the SSI team after colorectal surgery. Methods : In total, 955 patients underwent colorectal surgery at our hospital from 2014 to 2019. Of these 955 patients, 516 received therapeutic support by the SSI team from 2017 to 2019. All patients were evaluated using an SSI surveillance sheet, and we checked for reports of SSI once a month. Each attending physician performed SSI prophylaxis (use of new instruments before wound irrigation and closure). Results : SSI occurred in 80 (8.4%) patients. The incidence of SSI and the incidence of surface SSI were higher in the patients who did not receive intervention by the SSI team than in the patients who did. Organ / space SSI occurred in 18 patients. Among patients with surface SSI, Enterococcus was the most commonly detected bacteria. Among the 18 patients with organ / space SSI, 5 developed anastomotic leakage and 4 developed intra-abdominal abscesses. Conclusions : An SSI team for prevention and treatment of infection may contribute to reduction of SSI. J. Med. Invest. 68 : 256-259, August, 2021.

Abstract
Background : CKLF-like MARVEL transmembrane domain containing 6 (CMTM6) is the master regulator of programmed cell death-ligand 1 (PD-L1). We aimed to clarify the significance of CMTM6 expression in gastric cancer (GC). Methods : A total of 105 patients who had undergone curative surgical resection for stage II / III GC at Tokushima University Hospital were included in this study. The expression of CMTM6 was examined by immunohistochemistry. Additionally, the relationship of each expression level to several prognostic factors was examined using univariate and multivariate analyses. Results : CMTM6 was not positively correlated with any of the factors examined. The overall survival (OS) rates were significantly poorer in the CMTM6 high-expression group than in the CMTM low-expression group (5-year OS : 57.2% vs. 79.2%, respectively ; p < 0.05). Disease-free survival (DFS) was significantly poorer in the CMTM high-expression group than in the CMTM6 low-expression group (5-year DFS : 52.8% vs. 72.4%, respectively ; p < 0.05). Multivariate analysis confirmed CMTM6 expression as an independent prognostic factor in DFS (p < 0.05). CMTM6 expression tended to be correlated with PD-L1 expression (p = 0.07). Conclusions : CMTM6 is associated with a poor prognosis and immunotolerance through PD-L1 in GC. J. Med. Invest. 68 : 362-367, August, 2021.

Abstract
BACKGROUND The aim of this study was to investigate the influence of obesity and the usefulness of a preoperative weight loss program (PWLP) for obese patients undergoing laparoscopic colorectal resection (LCR). METHODS Study 1: 392 patients who underwent LCR for colorectal cancer were divided into two groups: those with a body mass index (BMI) ≥25 kg/m2 (n = 113) and those with a BMI <25 kg/m2 (n = 279). The influence of BMI on LCR was investigated. Study 2: Patients with a BMI ≥28 kg/m2 who were scheduled to undergo LCR (n = 7, mean body weight 87.0 kg, mean BMI 33.9 kg/m2) undertook a PWLP including caloric restriction and exercise for 29.6 (15-70) days. The effects of this program were evaluated. RESULTS Study 1: The BMI ≥25 kg/m2 group had a prolongation of operation time and hospital stay than the BMI <25 kg/m2 group. Study 2: The patients achieved a mean weight loss of 6.9% (-6.0 kg). The mean visceral fat area was significantly decreased by 18.0%, whereas the skeletal muscle mass was unaffected. The PWLP group had a significantly lower prevalence of postoperative complications compared with the BMI ≥25 kg/m2 group. CONCLUSION Obesity affected the surgical outcomes in LCR. A PWLP may be useful for obese patients undergoing LCR.

Abstract
BACKGROUND For advanced gastric cancer (AGC), peritoneal metastasis is the most common determinant of unresectability, but accurate preoperative diagnosis for peritoneal metastasis is challenging. Staging laparoscopy (SL) can detect unsuspected peritoneal metastasis. This study retrospectively evaluated the utility of SL and its indication in patients with AGC. METHODS In this study, we enrolled 114 patients with pathologically diagnosed gastric adenocarcinoma who underwent SL. RESULTS Of the 114 patients, 43 (37.7%) had peritoneal metastasis (P1 or CY1). Higher age, larger tumor size, type 4 GC, deeper tumor depth, elevated CA125, and ascites findings in preoperative CT were found to be significant predictors of peritoneal metastasis. In multivariate analysis, peritoneal metastasis was associated with type 4 GC (odds ratio [OR]: 6.11; 95% confidence interval [CI]: 1.87-19.8; P < .01) and ascites in CT (OR: 4.25; 95% CI: 1.48-12.1; P < .01). CONCLUSIONS Staging laparoscopy is an effective tool to detect peritoneal metastasis from AGC. It can increase the curative resection rate and decrease unnecessary laparotomies.

Abstract
Introduction: Transanal total mesorectal excision (TaTME) is a novel technique that overcomes the problem of access to the deep pelvis during radical surgery for mid-rectal and lower rectal cancer. Although TaTME has several important steps, the creation of the distal purse-string suture following TaTME plays an important role in ensuring the integrity of the colorectal anastomosis. However, this procedure represents a major technical challenge for the surgeon. Robot-assisted surgery may make this suturing procedure easier than laparoscopic surgery because it permits intuitive wrist movements and a three-dimensional view. The aim of the present study was to investigate the usefulness of transabdominal robotic purse-string suture during anastomosis in TaTME. Methods: Twenty-seven patients, who underwent anastomosis using a single stapling technique (SST) during the TaTME of mid-rectal or lower rectal cancer, were enrolled in the study. The patients were allocated to two groups: 11 patients underwent transabdominal robotic purse-string suturing (the Robot group) and 16 patients underwent transanal purse-string suturing (the Transanal group). The characteristics and short-term surgical outcomes of the participants were compared between the two groups. Results: The Robot group tended to have a shorter purse-string suturing time (541 ± 206 seconds versus 729 ± 310 seconds; P = .07). Regarding the shape of the "donut" after SST anastomosis, in the Transanal group, 5 of the 16 participants had incomplete donuts with muscular defects and required additional suturing, whereas in the Robot group, all the participants had complete donuts (P = .04). Conclusions: Transabdominal robotic purse-string suturing may facilitate the suturing procedure and contribute to reliable anastomosis.

Abstract
BACKGROUNDS The lymphocyte to C-reactive protein (CRP) ratio (LCR) is an indicator of systemic inflammation and host-tumor cell interactions. The aim of this study was to investigate the prognostic significance of LCR in lower rectal cancer patients who received preoperative chemo-radiotherapy (CRT). METHODS Forty-eight patients with lower rectal cancer who underwent CRT followed by curative surgery were enrolled in this study. Routine blood examinations were performed before and after CRT were used to calculate pre-CRT LCR and post-CRT LCR. The median LCR was used to stratify patients into low and high LCR groups for analysis. The correlation between pre- and post-CRT LCR and clinical outcomes was retrospectively investigated. RESULTS The pre-CRT LCR was significantly higher than the post-CRT LCR (11,765 and 6780, respectively, P < 0.05). The 5-year overall survival rate was significantly higher for patients with high post-CRT LCR compared with low post-CRT LCR (90.6% and 65.5%, respectively, P < 0.05). In univariate analysis, post-CRT LCR, post-CRT neutrophil to lymphocyte ratio, and fStage were significant prognostic factors for overall survival. In multivariate analysis, post-CRT LCR, but not other clinicopathological factors or prognostic indexes, was a significant prognostic factor for overall survival (P < 0.05). CONCLUSIONS Post-CRT LCR could be a prognostic biomarker for patients with lower rectal cancer.

Abstract
Delta-shaped anastomosis is nowadays an increasingly performed reconstruction method in laparoscopic distal gastrectomy for early gastric cancer. To date, anastomotic recurrence at the delta-shaped anastomotic site has not been reported. Surgery for this disease is more complicated than anastomotic recurrence at the site of conventional Billroth-I anastomosis. A 68-year-old female was referred to our institute with early gastric cancer on the posterior wall of the antrum. She underwent laparoscopic distal gastrectomy with delta-shaped Billroth-I anastomosis. Follow-up gastrofiberscopy 16 months after the operation revealed suspected anastomotic recurrence, and gastric biopsy revealed signet-ring cell carcinoma. Open total gastrectomy with reconstruction with the Roux-en-Y method was performed. At the distal part of the previous anastomosis, an adequate length of the duodenum was dissected from the pancreas. Then, the duodenum was transected 3 cm distal to the anastomosis using a linear stapler. The patient recovered well and was discharged on postoperative day 14. The patient is alive without re-recurrence 3 years postoperatively. We successfully treated a patient with anastomotic recurrence of gastric cancer after delta-shaped anastomosis. Adequate resection of the duodenal stump was performed without any residual tumor or injury to the pancreas. J. Med. Invest. 67 : 211-213, February, 2020.

Abstract
Background Anastomotic leakage has been reported as an independent risk factor for surgical recurrence at the anastomotic site in patients with Crohn's disease. An inadequate blood supply may contribute to this leakage. Real-time indocyanine green angiography has been useful for confirming vascular perfusion of the intestines. The aim of this study was to evaluate the use of intraoperative indocyanine green angiography to detect vascular perfusion of the intestines during ileocaecal resection in patients with Crohn's disease and colon cancer. Materials and methods We retrospectively evaluated the medical records of 26 consecutive patients with colon cancer arising in the caecum or ascending colon and 3 consecutive patients with Crohn's disease without a history of disease-related surgery. The patients in the 2 cohorts had undergone ileocaecal resection at Tokushima University Hospital between January 2018 and January 2021. After ileocaecal resection, blood flow was evaluated in ileal (oral) and colon (anal) stapled stumps by indocyanine green fluorescence angiography. The fluorescence time was defined as the time from indocyanine green injection and flush of the injection route to the point when the stump showed the strongest fluorescent signal in the monitor. Results The fluorescence time for the ileal and colon stumps in patients with Crohn's disease was 43.3 ± 8.8 s each and was significantly longer than the fluorescence time in the patients with colon cancer (29.4 ± 6.5 s and 29.6 ± 6.8 s, respectively) (P < 0.05). Conclusion Intraoperative indocyanine green fluorescence imaging is safe and reproducible for assessing intestinal perfusion prior to anastomosis in patients with colon cancer and Crohn's disease. Low blood supply increases leakage and surgical recurrence in Crohn's disease. Indocyanine green angiography is useful for evaluating the intestinal blood supply. Blood supply at anastomotic sites was lower in Crohn's disease than colon cancer.

Abstract
PURPOSE Venous thromboembolism (VTE) is a major complication after abdominal surgery; however, the best strategy for preventing VTE after surgery is not yet established. We performed this study to investigate the incidence of perioperative VTE and evaluate the efficacy of a VTE preventive strategy for patients undergoing surgery for colorectal cancer (CRC). METHODS The subjects of this retrospective analysis were 228 patients who underwent curative surgical resection for CRC between 2012 and 2016. The patients were treated with thromboprophylaxis including enoxaparin. We assessed the perioperative VTE occurrence rate and investigated the risk factors for postoperative VTE. RESULTS Among the 228 patients, 77 had a preoperative D-dimer level of > 1.0 μg/mL and 12 had deep vein thrombosis (DVT) diagnosed by ultrasonography preoperatively. Of the remaining 216 patients, short-term VTE (< 30 days) developed in two patients (0.9%) and long-term VTE (30 days-3 years) developed in seven (3.2%). The mortality rate of patients with VTE was 0%. The univariate analysis indicated that pulmonary disease was the risk factor for short-term VTE, whereas obesity, hyperlipidemia, and a preoperative history of pulmonary embolism were the risk factors for long-term VTE (p < 0.05). CONCLUSION The findings of this analysis show that our preventive protocol including enoxaparin is an effective strategy for preventing postoperative VTE.

Abstract
BACKGROUND/AIM Neutrophil-to-lymphocyte ratio (NLR) is an indicator of systemic inflammation and could be a predictive factor in malignant tumors. The aim of this study was to investigate the impact of NLR in patients with lower rectal cancer who received preoperative chemo-radiotherapy (CRT). PATIENTS AND METHODS Forty-eight patients with lower rectal cancer who underwent preoperative CRT and curative resection were enrolled. Blood samples were obtained before and after CRT. The relationship of NLR with clinical outcome was investigated. RESULTS Post-CRT NLR was higher compared to pre-CRT NLR. The patients with higher post-CRT NLR tended to have worse pathological response to CRT compared to those with low post-CRT NLR. The patients with high post-CRT NLR showed poorer 5-year overall survival and 3-year disease free survival while there was no correlation according to pre-CRT NLR. The univariate analysis showed that post-CRT stage and post-CRT NLR were associated with a poorer 5-year overall survival. CONCLUSION NLR after preoperative CRT could be a potential prognostic indicator for patients with lower rectal cancer.

Abstract
Background : The aim of this study was to investigate quality of life (QOL) and night-time sleep disturbance in colon cancer patients with middle risk chemotherapy for proper antiemetic therapy. Methods : The study enrolled 139 patients with colorectal cancer. All patients received oxaliplatin or irinotecan-based chemotherapy. Patients completed a questionnaire about chemotherapy-induced nausea and vomiting and sleep disturbance. Sleep disturbance was checked, and the relationship between sleep disturbance and nausea was analyzed. Results : The prevalence of nausea was 48.9% (68 / 139). The degree of the nausea was slight / moderate / severe in 51 / 11 / 6 patients, and 12 patients had vomiting. Appetite showed no change / slightly decreased / half / one-fourth / none in 51 / 34 / 33 / 6 / 7 patients. There were significant differences in the mental component summary (MCS) score and the role-social component score (RCS). (MCS : nausea(+) vs nausea(-) 46.4 ± 1.1 vs 54.1 ± 1.1 p < 0.01 RCS : nausea(+) vs nausea(-) 33.1 ± 2.1 vs 41.6 ± 2.1 p < 0.01). Using the MCS with a cut-off score of 50, patients were divided into two groups, and nausea was significantly correlated with a low MCS score. Furthermore, patients were divided into two groups using a Pittsburgh Sleep Quality Index cut-off score of 6, and sleep disturbance was correlated with old age and second-line chemotherapy. Conclusions : Nausea affects QOL and night-time sleep of colon cancer patients with middle risk chemotherapy. J. Med. Invest. 67 : 338-342, August, 2020.

Abstract
Purpose The aim of this study was to investigate the utility the three-dimensional (3D) imaging for laparoscopic gastrectomy performed by trainee surgeons. Methods 3D-reconstruction was performed using multi-detector computed tomography (MDCT) and SYNAPSE VINCENT software. Trainee surgeons made 3D-imaging and checked the anatomical structure. Thirty-three patients who underwent laparoscopic gastrectomy (LG) for gastric cancer were examined. Trainees performed 19 LG, while specialists performed 14 LG. The vascular pattern and the surgical outcomes were evaluated. Result 3D imaging depicted the correct positional relationship between the gastric vasculatures and the organs. Regarding vascular pattern detected by 3D imaging, the origins of the infrapyloric artery were the right gastroepiploic artery in 12 cases (36%), the gastroduodenal artery in eight cases (24%), the bifurcation of the right gastroepiploic artery and gastroduodenal artery in seven cases (21%), and not detected in one case (3%). The types of confluence of the infrapyloric vein were the right gastroepiploic vein in 16 cases (48%), the anterior superior pancreatoduodenal vein in 10 cases (30%), and not detected in seven cases (21%). Surgical outcomes were not different between trainee group using intraoperative 3D image with the specialist in instruction group without the intraoperative 3D image. Conclusions Preoperative 3D imaging might contribute to successful and safe LG by trainee surgeons. J. Med. Invest. 66 : 280-284, August, 2019.

Abstract
Purposes : Non-technical skills contribute to safe and efficient team performance. The aim of this study was to clarify the importance of non-technical skills by a questionnaire and the usefulness of feedback to the operator. Method : A questionnaire was administered to the operator and paramedical staff for 404 operations. Total and individual scores were compared, and the effect of feedback was analyzed by comparison between pre-feedback and post-feedback. Results : The total score of the paramedical staff was 100 [full score] [n = 186], 90-99 [n = 133], and 80-89 [n = 47]. In all cases, the score of the paramedical staff was significantly better than that of the operator. After feedback, the rate of a score less than 80 was significantly decreased. In junior doctor cases with laparoscopy, feedback tended to have a positive effect. Conclusions : Questionnaires completed by both surgeons and paramedical staff are useful for identifying problems with non-technical skills. J. Med. Invest. 67 : 83-86, February, 2020.

Abstract
INTRODUCTION Urethral injury is one of the most important complications that can occur during transanal total mesorectal excision in male patients with rectal cancer. This report shows the usefulness of intraoperative X-ray fluoroscopy to avoid urethral injury associated with transanal total mesorectal excision. MATERIALS AND SURGICAL TECHNIQUE Real-time navigation using fluoroscopy was performed to check the distance between the urethra and the dissection line at the level of the exposed rectourethral muscle, the middle level of the divided rectourethral muscle, and the level at which the prostate was identified. DISCUSSION The dissection was completed transanally up to the level of peritoneal reflection on the anterior side without urethral injury. Pathological examination confirmed that the circumferential resection margin was tumor free. This novel technique using intraoperative X-ray fluoroscopy is an easy-to-use approach that helps prevent urethral injury in male patient who undergo transanal total mesorectal excision for rectal cancer.

Abstract
AIM The purposes of this study are to present cases of emergency surgery in which gastrointestinal perforation occurred during bevacizumab administration, consider the indications for emergency surgery, and examine the safety of scheduled surgery after a washout period for bevacizumab. METHODS (a) We retrospectively investigated seven patients who underwent emergency surgery for bevacizumab-associated intestinal perforation. (b) We investigated 104 patients with advanced colorectal cancer treated with neoadjuvant therapy who underwent surgery from 2008 to 2018, retrospectively. RESULTS (a) In the seven patients undergoing emergency surgery for gastrointestinal perforation, the median bevacizumab administration and washout periods were 16 weeks and 24 days, respectively. A stoma was created in all patients except in those who were not candidates. Two patients developed postoperative abdominal abscesses, and two patients died from perioperative sepsis and gastrointestinal bleeding, respectively; both of these patients had poor performance status. (b) In patients receiving bevacizumab (n = 45) and patients treated with bevacizumab-free regimens as neoadjuvant therapy (n = 59), 31 and 52 patients received chemoradiotherapy, respectively. We found no correlation with postoperative complications with or without bevacizumab. CONCLUSION The surgical indications should be considered carefully in patients with gastrointestinal perforation secondary to bevacizumab administration. Meanwhile, after appropriate cessation time, scheduled surgery following bevacizumab administration is feasible.

Abstract
BACKGROUND In previous studies, we demonstrated the significant role of microRNA-449a (miR-449a) in colorectal cancer with in vivo and clinical samples. The importance of miR-449a in gastric cancer is still to be elucidated. This study examined the impact of miR-449a expression in tumor tissue and serum and investigated its potential as a prognostic marker in gastric cancer. MATERIALS AND METHODS Sixty-six patients with gastric cancer who underwent surgery were included in the study. miR-449a expression in tumor tissue and serum were investigated by real-time polymerase chain reaction analysis. The association of miR-449a expression with clinicopathological factors and patient prognosis were also investigated. RESULTS miR-449a expression was lower in tumor tissue than non-tumor tissue. miR-449a in tumor tissue negatively correlated with the malignancy of tumor and clinical stage. Increased carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels were seen at significantly higher frequencies in patients with low miR-449a expression. Patients with low miR-449a expression had poorer cancer-specific survival compared to those with high miR-449a expression. The univariate analysis showed that lymphovascular invasion, increased CEA and CA19-9 and a low expression of miR-449a were associated with a poorer 5-year cancer-specific survival. miR-449a expression level in serum correlated to that in tumor tissue and was also associated with tumor malignancy. CONCLUSION The miR-449a level in tumor tissue might be useful as a prognostic indicator for patients with gastric cancer and miR-449a in serum appears to reflect its expression in tumor tissue.

Abstract
BACKGROUND Sometimes intraoperative urethral injury occurs in Transanal total mesorectal excision (TaTME). The aim of this study is to investigate the usefulness of indocyanine green (ICG) fluorescent catheter system for avoiding intraoperative urethral injury in TaTME in experimental model. METHODS A urethral catheter was filled with the mixture of albumin and ICG and raw hams were applied in layers as the surrogate model of rectourethral muscle. The detectability of ICG fluorescence in this catheter was investigated by using laparoscope-type fluorescence camera system. RESULTS Fluorescence was detected when ICG was mixed with albumin or peripheral blood. ICG fluorescence could be detected within 4 mm depth of layered raw hams as the surrogate model. Quantitative analysis of the picture detected that ICG fluorescence plateaued in lower concentration than that of serum. CONCLUSION ICG fluorescent catheter system may be useful for avoiding intraoperative urethral injury in TaTME. J. Med. Invest. 67 : 285-288, August, 2020.

Abstract
BACKGROUND One of the major cause of anastomotic leakage (AL) in anterior resection of the rectum is insufficient blood flow of the remnant colon. The indocyanine green fluorescence system (ICG-FS) can visualize the blood flow of organs intra-operatively. The aim of this study is to investigate the usefulness of ICG-FS for evaluating the blood flow of the remnant colon in laparoscopic anterior resection. MATERIALS AND METHODS Rectal cancer patients (n=24) who underwent laparoscopic anterior resection were included in this study. After resection of the rectum, 7.5mg of ICG was administered intravenously, and the blood flow of the oral stump was evaluated by the ICG-FS. The relationship between the fluorescence time (FT) of the oral stump and AL was investigated retrospectively. RESULT Two of twenty-four patients (8.3%) suffered AL. The FT of these two cases were over 60 seconds. In the case with the FT was over 80 seconds, we performed additional resection of the late fluorescence portion of the remnant colon and could avoid AL. In patients whose FT was under 60 seconds, no patients suffered AL. CONCLUSION ICG-FS may be useful for evaluating the blood flow of the remnant colon to avoid AL in laparoscopic anterior resection.

Abstract
BACKGROUND/AIM We evaluated the clinical impact of FOLFOXIRI regimen aiming for conversion surgery in patients with unresectable multiple colorectal liver metastasis (CRLM). PATIENTS AND METHODS A total of 42 patients with unresectable multiple CRLM who received chemotherapy with molecular agents were included in the analysis. The clinical results of FOLFOXIRI with other regimens were compared. RESULTS The total conversion rate of 42 unresectable CRLM was 48.1%, and conversion cases had a better prognosis. Clinicopathological characteristics of conversion cases were more frequent in FOLFOXIRI induction, liver limited disease and maximum diameter × number (MDN) over 70. FOLFOXIRI achieved a higher conversion rate compared to other regimens (72.2% vs. 37.5%, p=0.0334), and significantly reduced the medication period until conversion surgery (median 5.8 courses) with a higher tumour necrotic rate. Consequently, the overall survival of conversion cases with FOLFOXIRI was better than that with other regimens (p=0.0055). CONCLUSION FOLFOXIRI plus molecular agents might provide a higher probability of conversion surgery with a prognostic benefit.

Abstract
INTRODUCTION The pre-operative three-dimensional (3D) imaging technique has resulted in a better surgical outcome for patients and has been used as an education and diagnostic tool. However, there are no reports concerning the usefulness of the 3D imaging technique in laparoscopic transabdominal pre-peritoneal repair (TAPP) so the aim of this study was to investigate the usefulness of the 3D imaging technique in laparoscopic TAPP as an educational tool for medical students. PATIENTS AND METHODS Six (6) patients who underwent laparoscopic TAPP for inguinal hernia were enrolled in this study. 3D reconstruction was performed from pre-operative computed tomography (CT) and the usefulness of pre-operative 3D simulation compared with intra-operative laparoscopic imaging was validated. Moreover, thirty (30) medical students at the university completed a multiple-choice questionnaire (MCQ) to determine the level of their satisfaction and understanding of anatomy resulting from the study. RESULT The local anatomy of the patients was identified as the same during the operation as the pre-operative 3D simulation. The results of the MCQ showed that most of the medical students were extremely (23%) or very (67%) satisfied with the effect of pre-operative 3D simulation on the quality of the surgery. Moreover, most students could understand the surgery anatomy by the 3D simulation extremely well (40%) or very well (47%) and agreed on the usefulness of this procedure for learning anatomy. CONCLUSIONS Pre-operative 3D simulation increases the understanding of detailed anatomy and virtual three-dimensional image analysis in laparoscopic TAPP is useful as an educational tool for medical students.

Abstract
BACKGROUND Heterotopic pancreas (HP) is a rare disease commonly found incidentally on imaging studies, at endoscopy or at autopsy and can be associated with abdominal pain, vomiting, heart burn, gastric outlet obstruction, and even dysphagia in very rare cases. Heinrich's classified HP into three groups, types1-3, with Heinrich's type 3 HP the rarest and difficult to diagnose properly because it has only pancreatic ducts but has no islet and acini. The aim of this study is to report a case of gastric outlet obstruction caused by type 3 HP with gastroduodenal invagination with reference to the literature and diagnosed finally by immuno-histochemical analysis. CASE PRESENTATION The case presented is a 40-year-old male presenting with vomiting and abdominal pain. Computed tomography (CT) revealed a cystic mass in the upper abdomen and he was referred to the Tokushima University. Gastric fiber showed that the pedunculated mass originated from the stomach. An open distal gastrectomy was performed. Pathologically, there was small glands proliferation in the sub-mucosal (SM) layer which was membrane and cytoplasm (MUC)1 positive and muscle proliferation. RESULTS This finding revealed the tumor as HP. Postoperative course was uneventful and the patient was discharged 12 days after surgery. The patient has remained well 12 months after surgery. CONCLUSIONS HP should be considered in the differential diagnosis of SM tumors with gastroduodenal invagination even if this is a rare symptom.

Abstract
BACKGROUND In a previous study, we demonstrated that deficiency of microRNA-449a (miR-449a) promoted colorectal tumorigenesis. In this study, the significance of miR-449a in the prognosis and relationship with HDAC1 in colorectal cancer was examined. MATERIALS AND METHODS Seventy-two patients with colorectal cancer and 16 patients with colorectal liver metastasis who underwent surgery were included. miR-449a expression in tumor tissue of resected specimen was investigated by real-time polymerase chain reaction and histone deacetylase 1 (HDAC1) expression was examined by immunohistochemistry. RESULTS Lymphovascular invasion and increased serum carcinoembryonic antigen levels were seen more frequent in patients with low miR-449a expression. Patients with low miR-449a expression were found to have a poorer prognosis than those with high expression. Vascular invasion, increased serum carbohydrate antigen 19-9 level and low miR-449a were associated with poorer disease-free survival. miR-449a expression was lower in metastatic liver tumor compared to primary tumor. HDAC1 positivity was higher in patients with low miR-449a. CONCLUSION miR-449a level might be a prognostic indicator for colorectal cancer and miR-449a might regulate HDAC1 expression.

Abstract
511 Background: The best method of venous thromboembolism (VTE) prevention after surgery for colorectal cancer remains unclear. It is reported that about 20-40% of high-risk patients were diagnosed as DVT and 2-4% was diagnosed as PE and its mortality rate is 0.5-1.0%. The aim of this study is to evaluate the incidence of postoperative VTE patients with colorectal adenocarcinoma and to evaluate the efficacy of VTE preventive strategy. Methods: A total of 264 patients who had undergone curative surgical resection for colorectal cancer at Tokushima University Hospital were included in this study (n = 264 colon: rectum = 1:0.57). All patients were measured D-dimer preoperatively. When D-dimer was ≥ 1.1, lower extremities ultrasonography (US) was performed. All patients were treated with Heparin (10,000U/24h) continuously intravenous injection from the day of surgery, and administered Enoxaparin (2,000U/24h) subcutaneous injection after 24h of the operation. Results: In all 264 patients, 74 (28%) were D-dimer ≥ 1.1 and 16 (6%) diagnosed VTE in US (proximal:distal type n = 6:1). 239 (91%) were treated with postoperative anticoagulant therapy. 2 developed perioperative VTE (symptomatic: asymptomatic = 1:1) and after discharge 12 developed postoperative VTE and mortality rate of VTE was 0%. Univariate analysis indicated that obesity (BMI ≥ 25), hyperlipidemia and preoperative PE were risk factors for deep venous thrombosis (DVT) (p < 0.0001, 0.014, 0.0135, respectively) and multivariate analysis revealed that obesity was an independent risk factor for postoperative DVT (p < 0.0001). Conclusions: Obesity (BMI ≥ 25) was independent risk factor for postoperative VTE. Our preventive protocol including screening using D-dimer and lower extremities US and treatment with Enoxaparin is considered as effective for prevention of postoperative VTE.

Abstract
584 Background: Clinical and molecular characteristics are different between Right-side and left-sided colorectal cancer (CRC). The aim of this study was to clarify the significance of the correlation of the Sidedness of CRC and tumor immunity. Methods: A total of 116 patients who underwent curative colectomy for stage II/III CRC were included in this study. The expression of PD-1, PD-L1, FoxP3, TGF-b, and IDO was examined by immunohistochemistry and the relationship of sidedness to several prognostic factors was examined. Results: In clinicopathological factors, there were no significant difference between right sided and left sided CRC except for differentiation. Regarding tumor immunity, there were no significant difference in PD-1 and IDO expression. However, Fox P3 (right side 72% vs. left side 59%) and TGFβ (right side 72% vs. left side 57%) tended to be highly expressed in right side(p < 0.1). PDL1 was significantly highly expressed in right side(right side 65% vs. left side 35%, p < 0.05). In OS and DFS, the patients with right sided tumor tended to have poor prognosis compared with left side (p < 0.1). The PD-L1 positive patients of right-sided tumor had poor prognosis (p < 0.05). Conclusions: Sidedness is associated with tumor immunity in colorectal cancer.

Abstract
BACKGROUND Surgical indication for hepatic resection is controversial in gastric cancer liver metastasis (GLM). The aim of this study is to clarify the effect of hepatic resection for GLM. METHODOLOGY Ten patients who underwent hepatic resection for GLM between 2001 and 2013 were enrolled in this study. Six patients underwent synchronous hepatic resection and gastrectomy, and the remaining four patients underwent metachronous hepatic resection. Six patients had solitary liver metastasis, and 4 patients had multiple liver metastasis. The median follow-up period was 12.4 months (the range being 0.5 months to 50 months). RESULT The actual 1- year and 3-year overall survival rates for the patients who underwent hepatic resection are 88.9% and 17.8%, respectively. The median survival time was 21.5 months. And the 1-year recurrence free survival time was 20.0%. The median recurrence free survival rate was 4.7 months. Regarding post-operative recurrence, synchronous hepatic resection tended to be a recurrence factor (p=0.08). CONCLUSION Hepatic resection for GLM has an acceptable outcome. Metachronous hepatic resection tends to have a better outcome than synchronous hepatic resection for the treatment of GLM. J. Med. Invest. 65:27-31, February, 2018.

Abstract
AIM The aim of this study was to investigate the effect of Roux-en-Y (RY) reconstruction on type 2 diabetes with gastric cancer in the early postoperative period. PATIENTS AND METHODS A total of 44 patients with gastric cancer with type 2 diabetes who underwent total gastrectomy (TG) or distal gastrectomy (DG) with Roux-en-Y reconstruction or DG with Bilroth I were enrolled. All three groups had their fasting glucose and daily insulin dose recorded preoperatively, on day 2 postoperatively (POD2) and at discharge. RESULTS The TG group showed low fasting glucose and daily insulin dose on POD2 compared to their preoperative state. On discharge, the fasting glucose and daily insulin dose were significantly lower in both TG and DG Roux-en-Y groups than preoperatively. CONCLUSION Roux-en-Y reconstruction showed early improvement of type 2 diabetes regardless of any body weight loss. The effect of Roux-en-Y reconstruction in TG on type 2 diabetes was more remarkable than that of DG.

Abstract
BACKGROUND/AIM Indoleamine 2,3-dioxygenase (IDO) down-regulates T cell activation, attenuates regulatory T cell (Treg) activation and is related to immune tolerance. The aim of the study was to clarify the significance of IDO expression and analyze the relationships between the expression of IDO, TGF-β, and Foxp3 in gastric cancer (GC). PATIENTS AND METHODS A total of 60 patients who underwent curative gastrectomy for stage III gastric cancer were included in the study. The expression of IDO, TGF-β, and Foxp3 was examined by immunohistochemistry and the relationship of each expression level to several prognostic factors was examined using univariate and multivariate analyses. RESULTS IDO expression was not positively correlated with any of the factors examined. IDO expression was positively correlated with TGF-β expression (p<0.05), and TGF-β expression was positively correlated with FoxP3 expression (p<0.05). Overall survival (OS) rates were significantly poorer in the IDO-positive group compared to the IDO-negative group (3-year OS, 78.5% vs. 90%, respectively; p<0.05). Multivariate analysis confirmed IDO expression as independent prognostic factors in OS. Disease-free survival (DFS) was significantly poorer in the IDO-positive group compared to the IDO-negative group (3-year DFS, 59.3% vs. 69.3%, respectively; p<0.05). CONCLUSION IDO is associated with poor prognosis and immuno-tolerance through attenuation of Treg activation in Stage III GC.

Abstract
AIM To evaluate the usefulness of Ki-67 index and survivin as predictive prognostic factors for rectal cancer treated with preoperative chemoradiotherapy. PATIENTS AND METHODS The Ki-67 index and survivin expression were examined in patients with stage II/III rectal cancer (n=46) by immunohistochemistry. Patients were divided into a high-group and a low-group for the Ki-67 index, and positive and negative groups for survivin expression. Overall and disease-free survival were compared between the groups, and the correlation between Ki-67 index and survivin expression was assessed. RESULTS The 5-year disease-free survival rate of the group with high Ki-67 index was significantly lower than that of the group with low Ki-67 index (53% and 88%, p=0.03), as was the 5-year overall survival rate (68% and 100%, p=0.03). Findings for survivin were not significant. CONCLUSION Ki-67 index and survivin may be useful biomarkers for rectal cancer with preoperative CRT.

Abstract
BACKGROUND Surgical resection is currently considered the only potentially curative option as a treatment strategy of colorectal liver metastases (CRLM). However, the criteria for selection of resectable CRLM are not clear. The aim of this study was to confirm a new prognostic indicator of CRLM after hepatic resection. PATIENTS AND METHODS One hundred thirty nine patients who underwent initial surgical resection from 1994 to 2015 were investigated retrospectively. Prognostic factors of overall survival including the product of maximum diameter and number of metastases (MDN) were analyzed. RESULTS Primary tumor differentiation, vessel invasion, lymph node (LN) metastasis, non-optimally resectable metastases, H score, grade of liver metastases, resection with non-curative intent and MDN were found to be prognostic factors of overall survival (OS). In multivariate analyses of clinicopathological features associated with OS, MDN and non-curative intent were independent prognostic factors. Patients with MDN ≥30 had shown significantly poorer prognosis than patients with MDN <30 in OS and relapse-free survival (RFS). CONCLUSION MDN ≥30 is an independent prognostic factor of survival in patients with CRLM and optimal surgical criterion of hepatectomy for CRLM.

Abstract
464 Background: In colorectal liver metastasis (CRLM), the difference of tumor malignancy between primary and metastatic lesion has been elucidated. Hypoxia inducible factor-1 (HIF-1) represent tumor malignancy including angiogenesis, tumor growth and epithelial mesenchymal transition (EMT). The aim of this study was to investigate the difference of tumor malignancy between metastatic and primary lesion of CRLM and its impact for patient’s prognosis. Methods: In an initial curative hepatectomy of 75 cases in CRLM, HIF-1 expression in primary and metastatic lesion was evaluated by immunostaining method (Sigma-Aldrich, HPA 001275). Staining score was classified as follows, staining intensity (0: negative, 1: low, 2: medium, 3: high) and staining area (0: 0%, 1: -25%, 2: 26-50%, 3: ≥ 51%), and defined more than 4 points as positive expression. We evaluated the clinicopathological features according to HIF-1 expression. Results: Regarding HIF-1 expression of metastatic site, we divided into the positive group (n = 54) and the negative group (n = 21). There was no difference between metastatic HIF-1 expression and clinicopathological factors. Nevertheless, in overall survival, multivariate analysis revealed that HIF-1 positive in metastasis (HR: 2.850, p = 0.042) and poor differentiation type of primary lesion (HR: 20.873, p = 0.001) were independent prognostic factors. HIF-1 positive and negative patients were 3 year survival of 95.2% and 58.6%, respectively. Also, in disease free survival, HIF-1 positive in metastasis (HR: 2.608, p = 0.004), Synchronous (HR: 1.794, p = 0.049), Grade BC (HR: 2.145, p = 0.008), and lymph node metastasis in primary lesion (HR: 2.070, p = 0.016) was identified. Regarding HIF-1 expression of primary site, we divided into 51 cases of positive group and 24 cases of negative group. There was no relationship to clinicopathological factors as well as HIF-1 expression in metastasis, besides HIF-1 expression of prognosis was not associated. Conclusions: In CRLM, HIF-1 expression in the metastatic lesion is not associated with the primary lesion and may be useful as prognostic marker.

Abstract
BACKGROUND The aim of this study was to investigate the significance of signal transducer and activator of transcription 4 (STAT4) expression and the correlation between STAT4 and interferon gamma (IFN-γ) in patients with gastric cancer. PATIENTS AND METHODS Sixty-two patients who underwent gastrectomy for gastric cancer were enrolled in the study. STAT4 and IFNG mRNA expression was evaluated by quantitative real-time polymerase chain reaction (PCR). Immunohistochemistry was performed to examine CD8+ T-cells, and STAT4 and IFN-γ expression. RESULTS STAT4 mRNA expression was significantly correlated with IFNG mRNA expression (p<0.05). Regarding disease-free survival, there was a significant difference between the groups with high and low STAT4 expression (5-year disease-free survival: 77.8% and 56.4%, p<0.05). Univariate analysis revealed that tumor differentiation and STAT4 expression were significant factors for tumor recurrence. CONCLUSION High expression of STAT4 in gastric cancer predicted a better clinical outcome. STAT4 might be a useful biomarker to identify patients at high risk of recurrence after gastrectomy.

Abstract
INTRODUCTION Curative laparoscopic gastrectomy (LG) is associated with good outcomes when performed for early gastric cancers. The aim of this study was to identify risk factors for recurrence after LG. METHODS 212 patients with gastric cancer who underwent gastrectomy were enrolled (LG: 143, open gastrectomy, OG: 69). Univariate analysis was used to assess overall (OS) and disease-free survival (DFS) in LG and OG group. Multivariate analysis was used to assess risk factors for recurrence after LG. RESULTS In LG, six cases of recurrence were observed (liver: 2, peritoneum: 4). Neither lymph node nor port-site recurrences were evident after LG. The 5-year DFS after LG was 91.4%. Based on univariate analysis of 5-year DFS, three negative prognostic factors-lymph node metastasis, lymphatic invasion, and venous invasion-were identified. The independent risk factor for recurrence of LG was lymph node metastasis. LG and OG showed no significant differences in 5-year DFS among Stage IA, IB, IIA, and IIB groups. Independent risk factors for recurrence after LG or OG were tumor invasion≥muscularis mucosa and lymph node metastasis. CONCLUSIONS DFS following LG is comparable to that following OG. Lymph node metastasis is an independent risk factor for gastric cancer recurrence after LG. J. Med. Invest. 64: 79-84, February, 2017.

Abstract
BACKGROUND Fbxw7 is a tumor suppressor through ubiquitination and degradation of multiple oncoproteins. Loss of Fbxw7 is frequently observed in various human cancers. In this study, we examined the role of Fbxw7 expression in colorectal liver metastasis (CRLM) and its mechanism. METHODS Fifty-six patients with CRLM who undergo curative resection were enrolled. Fbxw7 in tumor tissue was determined by immunohistochemistry. Patients were divided into two groups, the Fbxw7 high and low groups. Clinicopathological factors including miR-223 expression were compared between the high (n = 32) and low Fbxw7 groups (n = 24). RESULTS Fbxw7 expression in tumor tissues was significantly lower than that in normal tissues. The disease-free survival in the low Fbxw7 group was significantly worse than that in the high Fbxw7 group, and 3 years disease-free survival of the low and high Fbxw7 groups were 12.5% and 47.0%, respectively (P = 0.023). On multivariate analysis, loss of Fbxw7 was detected as one of the independent risk factors for recurrence of CRLM (hazard ratio: 2.390, P = 0.017). Likewise, Fbxw7 expression inversely correlated to miR-223 expression (P = 0.017). CONCLUSION Loss of Fbxw7 in tumor tissues could be a reliable predictor of recurrence after hepatectomy in patients with CRLM, and miR-223 might be a possible regulator of Fbxw7.

Abstract
BACKGROUND The aim of this study was to evaluate the clinical outcome of transanal local excision for cT1/cT2 lower rectal cancer following pre-operative chemoradiation therapy (CRT). PATIENTS AND METHODS Eleven patients who underwent pre-operative CRT for cT1/cT2 lower rectal cancer were retrospectively enrolled in this study. Surgical outcomes were compared between the group that underwent trasanal local excision (TLE) (n=6) and that which underwent total mesorectal excision (TME) (n=5). RESULTS Regarding surgical outcomes, there were significant differences between the two groups in operative time, rate of anal preservation and post-operative hospital stay. There were no differences between the two groups in the disease-free or overall survival rates. CONCLUSION The TLE following CRT had acceptable surgical outcomes. Surgeons should consider TLE following CRT for cT1/cT2 lower rectal cancer as a treatment option in selected patients.

Abstract
BACKGROUND/AIM Thrombospondin-1 (TSP1) is correlated with carcinogenesis occurring in cases of intestinal inflammation. The aim of this study was to clarify the role of TSP1 in gastric carcinogenesis. MATERIALS AND METHODS A total of 39 patients with gastric cancer who had undergone gastrectomy were enrolled. The expression of TSP1 mRNA in non-cancer tissues was determined. Furthermore, the expression of CD36, STAT3 and TGFβR2 mRNA in non-cancer tissues in two expression groups, the TSP1 high- and low-expression groups, were examined. RESULTS The expression of TSP1 was high in the mucosal-atrophy group and tended to be high in the Helicobacter pylori (H. pylori) (+) and multiple cancer groups. The levels of CD36, STAT3 and TGFβR2 mRNA were significantly higher in the TSP1-high group. TSP1 signaling pathway was induced in multiple cancer or atrophy (+) or H. pylori (+) compared to cases with single cancer, atrophy (-) and H. pylori (-). Expression of proteins involved in the TSP1 signaling pathway in non-cancer tissues with multiple gastric cancers were higher than that with single gastric cancer. CONCLUSION Expression of TSP1 in non-cancer tissue correlated with gastric carcinogenesis.

Abstract
Sphincter‐preserving procedures (SPPs) for surgical treatment of low‐lying rectal tumors have advanced considerably. However, their oncological safety for locally advanced low rectal cancer compared with abdominoperineal resection (APR) is contentious. We retrospectively analyzed cohort data of 1500 consecutive patients who underwent elective resection for stage II‐III rectal cancer between 2010 and 2011. Patients with tumors 2‐5 cm from the anal verge and clinical stage T3‐4 were eligible. Primary outcome was 3‐year local recurrence rate, and confounding effects were minimized by propensity score matching. The study involved 794 patients (456 SPPs and 338 APR). Before matching, candidates for APR were more likely to have lower and advanced lesions, whereas SPPs were carried out more often following preoperative treatment, by laparoscopic approach, and at institutions with higher case volume. After matching, 398 patients (199 each for SPPs and APR) were included in the analysis sample. Postoperative morbidity was similar between the SPPs and APR groups (38% vs 39%; RR 0.98, 95% CI 0.77‐1.27). Margin involvement was present in eight patients in the SPPs group (one and seven at the distal and radial margins, respectively) and in 12 patients in the APR group. No difference in 3‐year local recurrence rate was noted between the two groups (11% vs 14%; HR 0.77, 95% CI 0.42‐1.41). In this observational study, comparability was ensured by adjusting for possible confounding factors. Our results suggest that SPPs and APR for locally advanced low rectal cancer have demonstrably equivalent oncological local control.

Downregulation of microRNA-100/microRNA-125b is associated with lymph node metastasis in early colorectal cancer with submucosal invasion. Cancer Sci 2017; 108:390-397.

Abstract
A majority of early colorectal cancers (CRCs) with submucosal invasion undergo surgical operation, despite a very low incidence of lymph node metastasis. Our study aimed to identify microRNAs (miRNAs) specifically responsible for lymph node metastasis in submucosal CRCs. MicroRNA microarray analysis revealed that miR‐100 and miR‐125b expression levels were significantly lower in CRC tissues with lymph node metastases than in those without metastases. These results were validated by quantitative real‐time PCR in a larger set of clinical samples. The transfection of a miR‐100 or miR‐125b inhibitor into colon cancer HCT116 cells significantly increased cell invasion, migration, and MMP activity. Conversely, overexpression of miR‐100 or miR‐125b mimics significantly attenuated all these activities but did not affect cell growth. To identify target mRNAs, we undertook a gene expression array analysis of miR‐100‐silenced HCT116 cells as well as negative control cells. The Ingenuity Pathway Analysis, TargetScan software analyses, and subsequent verification of mRNA expression by real‐time PCR identified mammalian target of rapamycin (mTOR) and insulin‐like growth factor 1 receptor (IGF1R) as direct, and Fas and X‐linked inhibitor‐of‐apoptosis protein (XIAP) as indirect candidate targets for miR‐100 involved in lymph node metastasis. Knockdown of each gene by siRNA significantly reduced the invasiveness of HCT116 cells. These data clearly show that downregulation of miR‐100 and miR‐125b is closely associated with lymph node metastasis in submucosal CRC through enhancement of invasion, motility, and MMP activity. In particular, miR‐100 may promote metastasis by upregulating mTOR, IGF1R, Fas, and XIAP as targets. Thus, miR‐100 and miR‐125b may be novel biomarkers for lymph node metastasis of early CRCs with submucosal invasion.

Abstract
BACKGROUND Serum carcinoembryonic antigen (CEA) is used as an indicator of tumor progression in a variety of carcinomas. A subset of patients with hepatocellular carcinoma (HCC) exhibit increased serum CEA level, but the significance of this is unclear. In this study, we investigated the prognosis of patients with HCC with increased serum CEA, and explored the correlations with expression of carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) and epithelial-mesenchymal transition (EMT) and tumor angiogenesis. MATERIALS AND METHODS One hundred and twenty-three patients with HCC who underwent radical resection were divided into two groups according to a cut-off value of 5.0 ng/ml for serum CEA: high (n=24) and normal (n=99) groups. We compared the clinicopathological factors with serum CEA levels and its correlations with CEACAM1 expression, EMT-related factors and microvessel density (MVD) of tumor tissues by immunohistochemistry. RESULTS In the high CEA group, the disease-free survival (DFS) rate was significantly worse than in the normal CEA group. Multivariate analysis revealed that a high CEA level was an independent factor predictive of recurrence. Furthermore, increased serum CEA levels were positively correlated with CEACAM1 expression. Moreover, CEACAM1 expression was positively correlated with expression of EMT-related factors and MVD of tumor tissues. CONCLUSION Increased serum CEA level reflected CEACAM1 expression and was an independent factor predictive of recurrence in HCC through EMT and tumor angiogenesis.

Abstract
249 Background: Heat shock factor 1 (HSF1) is a master regulator of heat shock response. HSF1 is recently identified to play a multifaceted role in cancer progression. However, the clinical significance and biological effect of HSF1 in intrahepatic cholangiocarcinoma (IHCC) remain unknown. The aim of this study was to investigate the relationship between HSF1 expression and clinicopathological factors in IHCC patients after hepatic resection, and its possible mechanism for malignant behavior. Methods: Forty-nine patients with IHCC who undergo hepatic resection were enrolled in this study. HSF1 expressions in tumor tissue were determined by immunohistochemistry. Patients were divided into two groups, the HSF1 high and low expression group. Clinicopathological factors including prognosis were compared between the high group (n = 20) and low expression groups (n = 29) in tumor tissues. Furthermore, the correlation between HSF1 with Fbxw7 or Ki-67 expressions was also examined. Results: HSF1 expression in tumor tissues was significantly higher than that in normal tissues. HSF1 expression was not significantly correlated with any clinicopathological characteristics, including age, sex, tumor markers, maximum tumor size, tumor number, and tumor staging curability . The overall survival rate in the HSF1 high expression group was significantly worse than that in the HSF1 low expression group ( p= 0.018). On multivariate analysis, HSF1 high expression was detected as the independent prognostic factor. There was a significant inverse correlation between HSF1 and Fbxw7 expression ( p= 0.008). Ki67 labeling index was significantly higher in the high than in the low HSF1 expression group ( p= 0.030). Conclusions: HSF1 high expression in tumor tissues may be prognostic biomarker in IHCC. Targeting the Fbxw7/HSF1 axis might be a critical therapeutic strategy in IHCC.

S-1(80mg/m2), UFT(300mg/m2) were administered orally every day on radiation therapy, and S-1(80mg/m2,Oxaliplatin(40-60mg/m2),Bevacizumab(5mg/kg) were administered in SOX+Bev group. Total dose of radiation was 40Gy with four field technique. As a predictive factor, we measured miR-223 with real-time PCR using pre CRT biopsy specimens. Results: Clinical response by RECIST were as follows: SOX+Bev group: CR/PR/SD/PD = 1/21/3/0, S-1/UFT group: CR/PR/SD/PD = 1/32/26/0. Clinical response rate were 88% in SOX+Bev group, higher than 56.0% in S-1/UFT group. Pathological response grade were as follows: SOX+Bev group: 1a/1b/2/3 = 5/4/10/6,S-1/UFT group :1a/1b/2/3 = 13/16/27/3. Pathological response rate was 64% in SOX+Bev group, 51% in S-1/UFT group and there was no significant difference. The pCR rate was 24% in SOX+Bev group, significantly higher than 5% in S-1/UFT group (p < 0.05)B In S-1 group, miR-223 in responder group tended to be higher than non-responder group (p = 0.06). And in SOX+Bev group, miR-223 in Grade 3 group(8.89±9.41) was significantly higher than other group (3.19±4.64) (p = 0.05). Conclusions: Preoperative CRT with SOX+Bev regimen can improve response rate and bring high pCR rate. miR-223 may be promising predictive factor and useful to perform order made therapy. Clinical trial information: 13267.

Abstract
406 Background: Recently, the perihilar cholangiocarcinoma was defined as a tumor existing perihilar region between the right side of the umbilical portion of the left portal vein and the left side of the origin of the right posterior portal vein, in the General Rules for Clinical and Pathological Studies on Cancer of the Biliary Tract (The 6th edition). The study was aimed to investigate characteristics of intrahepatic cholangiocarcinoma (IHCC) according to tumor location. Methods: Study 1: Sixty-two IHCC patients who underwent hepatic resection were divided into the following 3 groups; peripheral type (n=41), perihilar type (n=10) and unclassified type (peripheral type with perihilar invasion: n=11). Clinicopathological data including CA19-9 and immnohistochemical staining of Ki67 and hypoxia inducible factor-1 (HIF-1) were compared. Study 2: The effect of 2 cycles of adjuvant gemcitabine combined with 5-FU and cisplatin (GFP) (Morine and Shimada. Hepatogastroenterology 2009) was retrospectively investigated, in advanced IHCC with one of 3 prognostic factors of LN metastasis, intrahepatic metastasis and R2 resection. Results: Study 1: There was no difference in background variables except for more frequent hilar biliary invasion in perihilar and unclassified types, and the largest tumor size in unclassified-type. The 5-year survival rate in the peripheral, perihilar and unclassified-types were 44%, 20% and 0%, respectively. In addition, CA19-9 level, Ki67 labelling index and positive rate of HIF-1 expression in the unclassified type were higher than those in other 2 types. Multivariate analysis revealed the unclassified type as an independent prognostic factor. Study 2: In 29 patients (47%) having one of the 3 prognostic factors, 9 patients including 4 unclassified-type IHCCs received the adjuvant GFP. The prognosis in GFP group tended to be better than that in non-GFP group (3-year survival rate: 38% vs. 6%, p = 0.07). Two patients with unclassified-type IHCC in non-GFP group died within 1 year after surgery. Conclusions: The unclassified-type IHCC indicated the most aggressive tumor biology, and the adjuvant GFP may be a useful strategy for such a highly malignant tumor with poor prognostic factors.

Abstract
780 Background: Recent advances in systemic chemotherapy, including molecular target agents, can introduce “Conversion surgery” and achieve R0 resection even for initially unresectable colorectal liver metastasis (CRLM). We investigated the optimal indication for initial surgical induction and treatment strategy for unresectable CRLM. Methods: Our current surgical indication for CRLM as follows: i) curative resection is achievable, ii) no limitation of tumor size and number, and iii) future remnant liver volume over 35%. Additionally, same indication is applied even after chemotherapy.Two hundreds forty-one cases from 1994 to 2015, consisted of 134 initially resectable case and 107 unresectable cases, were included. Among 107 unresectable cases, 55 cases received current chemotherapy such as FOLFOX, FOLFILI, XEROX and FOLFOXIRI. Results: 1) Optimal indication for initially resectable case:Multivariate analysis revealed MDN (Maximum Diameter × Number) index more than 30 of metastatic liver tumor (HR3.06), non-curative resection of metastatic liver tumor (HR4.082) and poor differentiation of primary tumor (HR11.14).2) Treatment strategy of unresectable case for “Conversion surgery” (FOLFOXIRI vs. other regimen): Forty-two unresectable cases with MDN > 30 were included. Of those 14 cases, FOLFOXIRI regimen was applied. Regarding clinicopathological factors, the use of molecular targeted drug was introduced in all patients of FOLFOXIRI group, but 67.9% patients of other regimen group. The “Conversion” rate in FOLFIXIRI group and other regimen group were 64.3% and 39.3% (p = 0.126), and median period until “Conversion” were 6.2 courses and 11.8 courses (p = 0.038). Regarding tumor necrotic rate, FOLFOXIRI regimen induced higher necrotic rate than other regimen group (77.9% vs. 50.4%, p = 0.073). Overall survival in FOLFOXIRI group has been better than that in other regimen group and 3-years survival rates were 83.3% and 48.0% (p = 0.044). Also, relapse free survival in FOLFOXIRI group was significantly better than that in other regimen group (p = 0.002). Conclusions: MDN can predict surgical outcome for CRLM. FOLFOXIRI plus molecular target drug may be a promising option for CRLM with MDN > 30.

Abstract
88 Background: Thrombospondin-1 (TSP1) correlated with the carcinogenesis in the intestinal inflammation. TSP1 binding CD36 evoked inflammation via the activation of TGFβ and STAT3. The aim of this study is to clarify the role of TSP1 in gastric carcinogenesis. Methods: Thirty-nine patients with gastric cancer who underwent gastrectomy were enrolled. The expression of TSP1 mRNA in non-cancer tissue was determined in clinicopathological factors (including mucosal inflammation and atrophy based on Sydney system). The expressions of CD36, STAT3 and TGFβR2 mRNA in the TSP1 high and low expression group in non-cancer tissue were examined. Results: TSP1 expression was high in mucosal atrophy group and tended to be high in Helicobacter pylori (H.pylori) (+) and multiple cancer group. In TSP1 high group, CD36, STAT3 and TGFβR2 mRNA showed significantly high. The expressions of TSP1 signaling pathway in multiple cancer or atrophy (+) or H.pylori (+) showed high compared with that in single cancer and atrophy (-) and H.pylori (-). The expressions associated TSP1 signaling pathway in non-cancer tissue with multiple gastric cancer showed higher than that with single gastric cancer. Conclusions: Our results indicated TSP1 expressions in non-cancer tissue correlated with gastric carcinogenesis.
