Abstract
BACKGROUND The efficacy and safety of endoscopic submucosal dissection (ESD) for tumors extending into the terminal ileum remain obscure. We aimed to evaluate the outcomes of ESD for tumors involving the ileocecal valve (ICV) with extension into the terminal ileum. METHODS Sixty-eight patients (40 men; mean age, 67 years) with 68 tumors involving the ICV that were resected by ESD between December 2013 and December 2018 were included and classified into Group A (21 tumors with extension into the terminal ileum) and Group B (47 tumors without extension). ESD outcomes were compared between groups. RESULTS The clinical features of the patients and tumors were not significantly different between the groups. There were no significant differences in en bloc resection rate (95% and 94%, respectively; p = 0.79), R0 resection rate (90% and 89%, respectively; p = 0.89), procedure time (95 ± 54 min and 94 ± 69 min, respectively; p = 0.64), postoperative bleeding rate (5% and 3%, respectively; p = 0.79), intraoperative perforation rate (0% and 4%, respectively; p = 0.34), delayed perforation rate (0% and 0%, respectively), or postoperative symptomatic stenosis rate (0% and 0%, respectively) between Groups A and B. No specific factors related to the outcomes of ESD were found by subgroup analysis according to the dominance and degree of circumference of the ICV. Local recurrence was observed in 1 patient in Group A who was retreated using ESD. CONCLUSIONS ESD for tumors involving the ICV with extension into the terminal ileum is safe and effective.

Abstract
BACKGROUND AND AIMS Many knives have been developed to improve the efficacy and safety of endoscopic submucosal dissection (ESD). We aimed to evaluate the efficacy and safety of scissor-type knives for colorectal ESD compared with needle-type knives. METHODS We performed a post-hoc propensity score-matched analysis in an 11-facility study between August 2013 and December 2018. A total of 2330 patients (2498 lesions) who underwent colorectal ESD were divided into needle-type (1923 patients, 2067 lesions) and scissor-type (407 patients, 431 lesions) knife groups. Short-term outcomes were compared between the 2 groups. RESULTS Two-to-one propensity score-matched analysis identified 814 (709 patients) and 407 (386 patients) lesions in the needle- and scissor-type knife groups, respectively. The median resection speed was significantly faster in the needle-type group (18.3 mm2/min) than in the scissor-type group (13.2 mm2/min, P < .0001), whereas en-bloc and histologic complete resection rates were not significantly different between the needle- and scissor-type groups (96.8% [788/814] vs 98.3% [400/407], P = .1888 and 95.1% [774/814] vs 95.6% [389/407], P = .7763, respectively). The rate of lesions resected using a single knife was significantly higher in the scissor-type group (98.5% [401/407]) than in the needle-type group (43.9% [357/814], P < .0001). Rates of intraoperative perforation and delayed bleeding were significantly lower in the scissor-type group than in the needle-type group (.7% [3/407] vs 2.5% [20/814], P = .0431 for each). CONCLUSIONS Scissor-type knives are safer for colorectal ESD. However, they are associated with slower resection speeds compared with needle-type knives.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) has become a widely accepted treatment method for colorectal tumors; however, there are some persistent problems. This multi-center study aimed to characterize the risk factors for incomplete resection and perforation in standardized colorectal ESD procedures. METHODS This study included 2423 consecutive patients who underwent ESD for 2592 colorectal tumors between August 2013 and December 2018 at 11 institutions (1 academic hospital and 10 affiliated hospitals) from the Hiroshima GI Endoscopy Research Group. We evaluated the risk factors for interruption, piecemeal resection, and perforation of standardized colorectal ESD in relation to clinicopathologic and endoscopic characteristics. RESULTS The incidences of interruption, piecemeal resection, and perforation were 0.7%, 2.9%, and 3.0%, respectively. Multivariate analysis identified the following risk factors for interruption: perforation during the procedure, deep submucosal invasion (> 1000 μm), poor scope operability, and severe submucosal fibrosis. The risk factors for piecemeal resection included poor scope operability, severe submucosal fibrosis, and procedure time (≥ 85 min). The risk factors for perforation during the procedure were severe submucosal fibrosis, poor scope operability, procedure time (≥ 85 min), and tumor size (≥ 40 mm). Independent risk factors for severe submucosal fibrosis included a history of biopsy and lesions located on the fold or flexure. CONCLUSIONS Severe submucosal fibrosis and poor scope operability are the common risk factors for interruption, piecemeal resection, and perforation in standardized colorectal ESD.

Abstract
BACKGROUND We analyzed the influence of preceding endoscopic submucosal dissection (ESD) on the prognosis of patients with T1 colorectal carcinoma (CRC) after additional surgery using propensity-score matching. METHODS 1638 consecutive patients with T1 CRC were retrospectively identified between January 1998 and December 2016 at the Hiroshima GI Endoscopy Research Group. We assessed 602 patients with 602 T1 CRC who underwent additional surgery after ESD (n = 216) or surgery alone (n = 386). The enrolled patients were treated according to the Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines 2016, and were defined as non-endoscopically curable (non-e-curable) when they did not satisfy its curative criteria. We analyzed the pathological characteristics and the prognosis of non-e-curable patients using propensity-score matching between the additional surgery after ESD and surgery alone groups. RESULTS There were no cases of recurrence and lymph node metastasis among the e-curable patients. The rate of lymph node metastasis and recurrences in the non-e-curable patients were 10.8% and 2.6%, respectively. After propensity-score matching, there were no significant differences in the 5-year overall survival rates (96.9% vs. 92.0%), 5-year disease-free survival rates (96.7% vs. 96.7%) and 5-year disease-specific survival rates (100% vs. 98.6%) after treatment of T1 CRCs between the 2 groups in non-e-curable patients. CONCLUSIONS Preceding ESD with histological en bloc resection for patients with T1 CRC did not affect their oncologic behavior adversely after additional surgery.

Abstract
PURPOSE Long-term prognosis of T1 laterally spreading tumors (LSTs) after treatment have not been clarified. This study compared clinicopathological characteristics and long-term prognosis of T1 LSTs. METHODS We retrospectively assessed 169 patients with 169 T1 LSTs between January 1992 and December 2008 by ten hospitals. Patients who did not meet the Japanese Society for Cancer of the Colon and Rectum (JSCCR) 2016 guidelines for the treatment of colorectal carcinoma (CRC) criteria were defined as non-endoscopically curable. The number of non-endoscopically curable patients with LST-granular/ nodular mixed (LST-G-M) was 61, that with LST-non-granular/ flat elevated (LST-NG-FE) was 23, and that with LST-non-granular/ pseudo depressed (LST-NG-PD) was 23. Clinicopathological variables and long-term prognosis were analyzed. RESULTS For overall patients, tumor size, number of non-endoscopically curable cases, and rate of submucosal invasion depth ≥ 1000 μm for the LST-G-M group were significantly higher than those in the other groups. For non-endoscopically curable patients, the tumor size for those with LST-G-M was significantly larger than those in the other groups. The rate of submucosal invasion width ≥ 4000 μm and type B/C muscularis mucosae with LST-G-M was higher than that with LST-NG-FE. All recurrences occurred in non-endoscopically curable patients with LST-G-M. Five-year overall and disease-free survivals for non-endoscopically curable patients with LST-G-M were significantly shorter than those for patients with non-endoscopically curable LST-NG-FE and PD. CONCLUSIONS Our data supported adequacy of the JSCCR guidelines for the treatment of CRC criteria for endoscopically curable patients after T1 LSTs treatment. Patients with T1 LST-G-M should be followed up more carefully.

Abstract
BACKGROUND AND AIMS Although advanced high-volume centers have reported good outcomes of colorectal endoscopic submucosal dissection (ESD), a limited number of highly skilled experts in specialized institutions performed these procedures. We undertook a retrospective multicenter survey, which included nonspecialized hospitals, to investigate the clinical outcomes of colorectal ESD. METHODS We recruited 1233 consecutive patients with 1259 colorectal tumors resected by ESD at 12 institutions. We evaluated the en bloc resection rate, histologic complete resection rate, curative (R0) resection rate, adverse events, and the long-term prognoses, including local recurrence, metachronous tumor development, and survival rate. RESULTS The en bloc, histologic complete, and R0 resection rates were 92.6%, 87.4%, and 83.7%, respectively. The delayed bleeding, intraoperative perforation, and delayed perforation rates were 3.7%, 3.4%, and .4%, respectively. The long-term outcomes analysis included 1091 patients (88.4%). Local recurrences occurred in 1.7%, and metachronous tumors (>5 mm) developed in 11.0% of the patients. The 3- and 5-year overall survival rates were 95.1% and 92.3%, respectively. The number of colonic tumors, severe submucosal fibrosis, and en bloc resection rates were significantly higher in the high-volume centers (Group H) than those in the low-volume centers (Group L). The average tumor size in Group H was significantly larger than that in Group L. CONCLUSIONS Colorectal ESDs are feasible, have acceptable adverse event risks, and favorable long-term prognoses.

Abstract
BACKGROUND We aimed to clarify the long-term outcomes of patients with T1 colorectal carcinoma (CRC) after endoscopic resection (ER) and surgical resection. METHODS We examined T1 CRC patients treated during 1992-2008 and who had ≥5 years of follow-up. Patients who did not meet the curative criteria after ER according to the Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines were defined as "non-endoscopically curable" and classified into three groups: ER alone (Group A: 121 patients), additional surgery after ER (Group B: 238 patients), and surgical resection alone (Group C: 342 patients). Long-term outcomes and predictors of recurrence were analyzed. RESULTS Of the 882 patients with T1 CRC, 701 were non-endoscopically curable. Among these patients, recurrence and 5-year overall survival (OS) rates were 0.6 and 91.1%, respectively. In Groups A, B, and C, recurrence rates were 5.0, 5.5, and 3.8%, OS rates were 79.3, 92.4, and 91.5% (p < 0.01), and 5-year disease-free survival (DFS) rates were 98.1, 97.9, and 98.5%, respectively. Thirty-two patients experienced local recurrence or distant/lymph node metastasis (Group A: 6; Group B: 13; Group C: 13) and 14 patients died of primary CRC (Group A: 3; Group B: 7; Group C: 4). Age ≥65 years, protruded gross type, positive lymphatic invasion, and high budding grade were significant predictors of recurrence in non-endoscopically curable patients. CONCLUSIONS Our findings supported the JSCCR criteria for endoscopically curable T1 CRC. ER for T1 CRC did not worsen the clinical outcomes of patients who required additional surgical resection.

Abstract
BACKGROUND The risk for lymph node metastasis and the prognostic significance of pedunculated-type T1 colorectal carcinomas (CRCs) require further study. We aimed to assess the validity of the 2014 Japanese Society for Cancer of the Colon and Rectum (JSCCR) guidelines based on long-term outcomes of pedunculated-type T1 CRCs. METHODS In this multicenter retrospective cohort study, we examined 176 patients who underwent resection endoscopically or surgically at 14 institutions between January 1990 and December 2010. Patients meeting the JSCCR curative criteria were defined as "endoscopically curable (e-curable)" and those who did not were "non-e-curable". We evaluated the prognosis of 116 patients (58 e-curable, 58 non-e-curable) who were observed for >5 years after treatment. RESULTS Overall incidence of lymph node metastasis was 5 % (4/81; 95 % confidence interval 1.4-12 %: three cases of submucosal invasion depth ≥1000 μm [stalk invasion] and lymphatic invasion, one case of head invasion and budding grade 2/3). There was no local or metastatic recurrence in the e-curable patients, but six of them died of another cause (observation period, 80 months). There was no local recurrence in the non-e-curable patients; however, distant metastasis was observed in one patient. Death due to the primary disease was not observed in non-e-curable patients, but six of them died of another cause (observation period, 72 months). CONCLUSIONS Our data support the validity of the JSCCR curative criteria for pedunculated-type T1 CRCs. Endoscopic resection cannot be considered curative for pedunculated-type T1 CRC with head invasion alone.

Abstract
BACKGROUND The lower rectum close to the dentate line has distinct characteristics, making endoscopic submucosal dissection (ESD) of tumors challenging. We assessed clinical outcomes of ESD for such patients with hemorrhoids. METHODS Sixty-four patients (mean age, 68 years) underwent ESD for anorectal tumors close to the dentate line. We divided patients into those with (Group A, 45 patients) and without hemorrhoids (Group B, 19 patients). We examined en bloc and histological en bloc resection rates, procedure time, complication rates, and postoperative prognosis after ESD. RESULTS The mean tumor size was 43 mm. Histologic diagnoses were adenoma (42 %, 27/64), carcinoma in situ (44 %, 28/64), and T1 carcinoma (14 %, 9/64). There was no significant difference in en bloc resection (93 %, 42/45 vs. 95 %, 18/19) or postoperative bleeding rates (16 %, 7/45 vs. 11 %, 2/19) between Groups A and B, respectively. The mean procedural durations were 120 and 124 min, respectively, in Groups A and B. No perforations occurred. There was no significant difference in postoperative anal pain rate between Groups A (18 %, 8/45) and B (16 %, 3/19), and it resolved within a few days in all cases. There was one case of stricture in Group B. Two patients with T1 carcinoma underwent additional surgery, one underwent chemotherapy, and five had no additional treatment. No recurrence occurred during the follow-up period of 38 months. CONCLUSIONS ESD is safe and effective for anorectal tumors close to the dentate line in patients with hemorrhoids.

Abstract
AIM Vascular endothelial growth factor C (VEGF-C) is known to be associated with the development of the lymphatic vascular system. The aim of this study was to elucidate the clinical significance of VEGF-C expression and microvessel density (MVD) at the deepest invasive site in advanced colorectal carcinoma (CRC). METHODS 152 patients who had undergone surgical resection for advanced CRC entered this study. VEGF-C expression was examined immunohistochemically with anti-VEGF-C polyclonal antibody C-20. Tumor MVD was determined immunohistochemically with anti-CD34 antibody. VEGF-C expression was defined as positive if distinct staining of the cytoplasm was observed in at least 10% of tumor cells at the deepest invasive site, central portion and superficial part of the tumor. MVD was estimated by averaging the count of three x400 fields in the most vascular area at the deepest invasive site. RESULTS VEGF-C expression was detected in 71 of 152 lesions (46.7%) at the deepest invasive site. VEGF-C expression correlated significantly with poorer histologic grade, depth of invasion, lymphatic invasion, lymph node metastasis, venous invasion, liver metastasis and Duke's stage. At the central portion and superficial part, there were no significant differences between VEGF-C expression and clinicopathological findings. VEGF-C expression at the deepest invasive site also correlated significantly with MVD. In cases with curative surgery, patients with VEGF-C expression at the deepest invasive site had a significantly poorer prognosis than those without VEGF-C expression. Furthermore, prognosis for patients with both VEGF-C expression and high MVD at the deepest invasive site was significantly poorer than that of patients without VEGF-C expression and with low MVD. Multivariate analysis with logistic regression for 5-year survival in patients with curative surgery showed that lymph node metastasis and VEGF-C expression were significant risk factors. CONCLUSION VEGF-C expression at the deepest site of tumor invasion can be a useful predictor of poor prognosis in advanced CRC and show a close relation to angiogenesis.

Abstract
OBJECTIVE Malignant cells exhibit increased glucose uptake and utilization in vitro and in vivo. This process is thought to be mediated by the glucose transporter (Glut) family. The aim of this study was to elucidate the clinical significance of Glut1 expression at the site of deepest invasion as a predictor of the invasive/metastatic potential and prognosis of advanced colorectal carcinoma (CRC). METHODS One hundred and fifty-two patients who had undergone surgical resection for advanced CRC were entered in this study. Histologic subclassifications at the deepest invasive site included well-differentiated (W), moderately to well-differentiated (Mw), moderately to poorly differentiated (Mp), poorly differentiated (Por) and mucinous (Muc) adenocarcinomas. Glut1 expression was examined immunohistochemically with a labeled streptavidin-biotin kit using anti-Glut1 polyclonal antibody MYM. As a marker of cell proliferation, Ki-67 expression was also examined. All immunoreactivity was analyzed at the deepest invasive site, central portion and superficial part. The immunohistochemical expression of Glut1 was defined as positive if distinct staining of the membrane or cytoplasm was observed in at least 30% of tumor cells. RESULTS Glut1 expression was detected in 56 of 152 lesions (36.8%) at the deepest invasive site. The incidence of Glut1 expression at the deepest invasive site correlated significantly with histologic grade (W/Mw grade, 28% vs. Mp/Por/Muc grade, 48%), depth of invasion (invasion of muscularis propria/invasion of subserosa or subadventitia, 29% vs. invasion of serosa or adventitia/invasion of adjacent structures, 52%), lymphatic invasion (absence of lymphatic invasion, 19% vs. presence of lymphatic invasion, 40%), lymph node metastasis (absence of lymph node metastasis, 25% vs. presence of lymph node metastasis, 41%) and Duke's stage (Duke's <D, 32% vs. Duke's D, 51%). In the central portion and superficial part, there were no significant differences between Glut1, Ki-67 expression and clinicopathological findings. Glut1 expression at the deepest invasive site correlated significantly with the Ki-67 labeling index. In cases of curative surgery, patients with Glut1-positive lesions at the deepest invasive site showed a significantly poorer prognosis than those with Glut1-negative lesions. Multivariate analysis with logistic regression for 5-year survival in patients who had undergone curative surgery showed that lymph node metastasis and Glut1 expression were significant risk factors. CONCLUSION These results indicate that Glut1 expression at the deepest site of tumor invasion can be a useful predictor of a high malignant potential and poor prognosis in advanced CRC.

Abstract
The deepest invasive portion of colorectal carcinoma (CRC) is considered to be the part, which ultimately will invade, spread locally and give metastasis. We have previously reported that histologic differentiation at the deepest invasive portion of CRC closely correlate with metastatic potential and is useful in understanding the curability of endoscopic mucosal resection (EMR). The aim of this study is to clarify the conditions of curative EMR for CRC with submucosally (sm) massive invasion. A total of 521 cases with sm invasive CRC (Group A, 470 surgically resected cases; Group B, 51 followed-up cases after EMR) were studied. The depth of sm invasion was defined as the practically measured distance from muscularis mucosae. Histologic subclassification was performed at the deepest invasive tumor margin as: well-differentiated (W), moderately differentiated (M) and poorly differentiated (Por). By assessing glandular configuration and cellular arrangement, M type was further subdivided into two different groups; moderately-well differentiated (Mw) and moderately-poorly differentiated (Mp). In group A, lymph node (LN) metastasis was detected in 45 (9.6%) of 470 cases. W or Mw lesions showed LN metastasis in 4.9% (19/388). Mp or Por lesions showed LN metastasis in 37.3% (25/67) (W/Mw vs Mp/Por; p<0.01). Of 45 cases with LN metastasis that could be measured the practical distance of sm invasion, W or Mw lesions showed no LN metastasis in cases within 1,500 micrometer invasion. However, Mp or Por lesions showed LN metastasis in cases within 1,500 micrometer invasion (5/15, 33.3%, minimum 400 micrometer invasion; so-called scanty invasion). In group B, none of 51 cases died of LN metastasis and showed no other metastasis, although 17 cases (33.3%) showed an sm invasion more than 1,500 micrometer. These results indicated that CRC even with sm massive invasion can be cured by complete EMR on conditions that the depth of sm invasion is within 1,500 micrometer and histologic grade at the deepest invasive portion is W or Mw, if there are no vessel involvement. However, cases with Mp or Por grade were not curative by EMR, even if they showed an sm scanty invasion.
