Abstract
BACKGROUND AND AIMS The Zhongshan colorectal endoscopic submucosal dissection (CR-ESD) score model was proposed to grade the technical difficulty of CR-ESD. The objective of this study was to prospectively validate and update the score model. METHODS A multicenter prospective cohort analysis of CR-ESD was conducted. Individual data on patients, lesions, and outcomes of CR-ESD were used to validate the original model and further refine the difficulty of the prediction model. Data were randomly divided into discovery and internal validation cohorts. A multivariate Cox regression analysis was conducted on the discovery cohort to develop an updated risk-scoring system, which was then validated. RESULTS Five hundred forty-eight patients with 565 colorectal lesions treated by ESD from 4 hospitals were included. In the prospective validation cohort, the area under the receiver-operating characteristic (ROC) curve for the original model was .707. Six risk factors were identified and assigned point values: tumor size (2 points for 30-50 mm, 3 points for ≥50 mm), at least two-thirds circumference of the lesion (3 points), tumor location in the cecum (2 points) or flexure (2 points), laterally spreading tumor-nongranular lesions (1 point), preceding biopsy sampling (1 point), and NBI International Colorectal Endoscopic type 3 (3 points). The updated model had an area under the ROC curve of .738 in the discovery cohort and of .782 in the validation cohort. Cases were categorized into easy (score = 0-1), intermediate (score = 2-3), difficult (score = 4-6), and very difficult (score ≥7) groups. Satisfactory discrimination and calibration were observed. CONCLUSIONS The original model achieved an acceptable level of prediction in the prospective cohort. The updated model exhibited superior performance and can be used in place of the previous version.

Abstract
BACKGROUND Gastric subepithelial tumors (SETs) may harbor potential malignancy. Although it is well recognized that large SETs should be resected, the precise treatment strategy remains controversial. Compared to surgical resection, endoscopic resection (ER) has many advantages; however, ER of SETs in the cardia is challenging. AIM To evaluate the safety and efficacy of endoscopic full-thickness resection (EFTR) for the treatment of gastric cardia SETs. METHODS We retrospectively reviewed data from all patients with SETs originating from the muscularis propria layer in the gastric cardia that were treated by EFTR or submucosal tunneling ER (STER) at Zhongshan Hospital Fudan University between November 2014 and May 2022. Baseline characteristics and clinical outcomes, including procedure times and complications rates, were compared between groups of patients receiving EFTR and STER. RESULTS A total of 171 tumors were successfully removed [71 (41.5%) tumors in the EFTR and 100 (58.5%) tumors in the STER group]. Gastrointestinal stromal tumors (GISTs) were the most common SET. The en bloc resection rate was 100% in the EFTR group vs 97.0% in STER group (P > 0.05). Overall, the EFTR group had a higher complete resection rate than the STER group (98.6% vs 91.0%, P < 0.05). The procedure time was also shorter in the EFTR group (44.63 ± 28.66 min vs 53.36 ± 27.34, P < 0.05). The most common major complication in both groups was electrocoagulation syndrome. There was no significant difference in total complications between the two groups (21.1% vs 22.0%, P = 0.89). CONCLUSION EFTR of gastric cardia SETs is a very promising method to facilitate complete resection with similar complications and reduced operative times compared to STER. In cases of suspected GISTs or an unclear diagnosis, EFTR should be recommended to ensure complete resection.

Abstract
Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor among gastrointestinal tumors, with an inherent potential for malignancy. The primary approach to addressing GIST remains surgical intervention. Laparoscopic and endoscopic cooperative surgery (LECS) has emerged as an innovative treatment approach for GIST. LECS includes various techniques, such as classic LECS, inverted LECS, and laparoscopic-assisted endoscopic full-thickness resection, all of which aim to combine the advantages of laparoscopy and endoscopy. This treatment offers benefits such as accurate localization, complete lesion removal, and a good prognosis. Generally, LECS can be used for GIST with a tumor diameter less than 50 mm, which cannot be completely removed through traditional endoscopic surgery. The clinical application of LECS deserves further exploration and expansion in the future, ultimately benefiting patients.

Abstract
BACKGROUND Improved adenoma detection at colonoscopy has decreased the risk of developing colorectal cancer. However, whether image-enhanced endoscopy (IEE) further improves the adenoma detection rate (ADR) is controversial.
AIM To compare IEE with white-light imaging (WLI) endoscopy for the detection and identification of colorectal adenoma.
METHODS This was a multicenter, randomized, controlled trial. Participants were enrolled between September 2019 to April 2021 from 4 hospital in China. Patients were randomly assigned to an IEE group with WLI on entry and IEE on withdrawal (n = 2113) or a WLI group with WLI on both entry and withdrawal (n = 2098). The primary outcome was the ADR. The secondary endpoints were the polyp detection rate (PDR), adenomas per colonoscopy, adenomas per positive colonoscopy, and factors related to adenoma detection.
RESULTS A total of 4211 patients (966 adenomas) were included in the analysis (mean age, 56.7 years, 47.1% male). There were 2113 patients (508 adenomas) in the IEE group and 2098 patients (458 adenomas) in the WLI group. The ADR in two group were not significantly different [24.0% vs 21.8%, 1.10, 95% confidence interval (CI): 0.99-1.23, P = 0.09]. The PDR was higher with IEE group (41.7%) than with WLI group (36.1%, 1.16, 95%CI: 1.07-1.25, P = 0.01). Differences in mean withdrawal time (7.90 ± 3.42 min vs 7.85 ± 3.47 min, P = 0.30) and adenomas per colonoscopy (0.33 ± 0.68 vs 0.28 ± 0.62, P = 0.06) were not significant. Subgroup analysis found that with narrow-band imaging (NBI), between-group differences in the ADR, were not significant (23.7% vs 21.8%, 1.09, 95%CI: 0.97-1.22, P = 0.15), but were greater with linked color imaging (30.9% vs 21.8%, 1.42, 95%CI: 1.04-1.93, P = 0.04). the second-generation NBI (2G-NBI) had an advantage of ADR than both WLI and the first-generation NBI (27.0% vs 21.8%, P = 0.01; 27.0% vs 21.2.0%, P = 0.01).
CONCLUSION This prospective study confirmed that, among Chinese, IEE didn’t increase the ADR compared with WLI, but 2G-NBI increase the ADR.

Abstract
BACKGROUND Porphyromonas gingivalis plays an oncogenic role in development and progression of esophageal squamous cell carcinoma (ESCC). However, the impact of P. gingivalis on local recurrence of early ESCC or precancerous lesion after ESD treatment remains unknown. The present study aimed to evaluate the impact of P. gingivalis on local recurrence after ESD treatment of early ESCC or high-grade dysplasia (HGD). METHODS The amount of P. gingivalis was assessed by immunohistochemistry in 205 patients with early ESCC or HGD. Univariate and multivariate Cox regression analyses were performed to determine the effect of P. gingivalis on local recurrence. Propensity score matching analysis was performed to reduce the imbalance of baseline characteristics. A nomogram integrating significant prognostic factors was built for local recurrence prediction. RESULTS The amount of P. gingivalis increased significantly in neoplasms that invaded up to muscularis mucosa and submucosa compared with lesions confined to epithelium or lamina propria. Overabundance of P. gingivalis was positively associated with invasion depth, post-ESD stricture and local recurrence. Univariate and multivariate Cox regression analyses revealed that P. gingivalis, longitudinal length of lesion and lymphovascular invasion were independent predictors for post-ESD recurrence. A nomogram comprising P. gingivalis, lymphovascular involvement, and lesion length performed well for prediction of post-ESD local recurrence with the concordance indices of 0.72 (95%CI, 0.62 to 0.80), 0.72 (95%CI, 0.63 to 0.80), and 0.74 (95%CI, 0.65 to 0.83) in the validation cohort, the entire cohort, and the subcohort after PSM, respectively. CONCLUSION P. gingivalis overabundance is a risk factor and a potential predictor for local recurrence of early ESCC or HGD after ESD treatment. Thus, clearance of P. gingivalis represents an attractive strategy for prognosis improvement and for prevention of ESCC.

Abstract
BACKGROUND AND AIMS Endoscopic submucosal dissection (ESD) is a promising technique for removing superficial GI tumors, but ESD is technically difficult. The aim of this study was to establish a clinical score model for grading technically difficult colorectal ESD. METHODS Data on patients, lesions, and outcomes of colorectal ESD at 2 centers were analyzed. The objective parameter of successful ESD within 60 minutes was set as an endpoint to evaluate the difficulty. Independent predictors of difficulty in the derivation cohort were identified by multiple logistic regression analysis and used to develop a clinical score. We validated the score model in the validation cohort. RESULTS The clinical score comprised tumor size of 30 to 50 mm (1 point) or ≥50 mm (2 points), at least two-thirds circumference of the lesion (2 points), location in the cecum (1 point), flexure (2 points) or dentate line (1 point), and laterally spreading tumor nongranular lesions (1 point). Areas under the receiver operator characteristic curves for the score model were comparable (derivation [.70] vs internal validation [.69] vs external validation [.69]). The probability of successful ESD within 60 minutes in easy (score = 0), intermediate (score = 1), difficult (score = 2-3), and very difficult (score ≥4) categories were 75.0%, 51.3%, 35.6%, and 3.4% in the derivation cohort; 73.3%, 47.9%, 31.8%, and 16.7% in the internal validation cohort; and 79.5%, 66.7%, 43.3%, and 20.0% in the external validation cohort, respectively. CONCLUSIONS This clinical score model accurately predicts the probability of successful ESD within 60 minutes and can be applied to grade the technical difficulty before the procedure.

Abstract
Background NOD-like receptors affect multiple stages of cancer progression in many malignancies. NACHT, LRR, and PYD domain-containing protein 7 (NLRP7) is a member of the NOD-like receptor family, although its role in tumorigenesis remains unclear. By analyzing clinical samples, we found that NLRP7 protein levels were upregulated in colorectal cancer (CRC). We proposed the hypothesis that a high level of NLRP7 in CRC may promote tumor progression. Here, we further investigated the role of NLRP7 in CRC and the underlying mechanism. Methods NLRP7 expression in human CRC and adjacent non-tumorous tissues was examined by quantitative real-time polymerase chain reaction (qRT-PCR), western blotting, and immunohistochemistry. The effect of NLRP7 in CRC progression was investigated in vitro and in vivo. Proteins interacting with NLRP7 were identified by immunoprecipitation and mass spectrometry analysis while immunofluorescence staining revealed the cellular location of the proteins. Cellular ubiquitination and protein stability assays were applied to demonstrate the ubiquitination effect on NLRP7. Cloning and mutagenesis were used to identify a lysine acceptor site that mediates NLRP7 ubiquitination. Cytokines/chemokines affected by NLRP7 were identified by RNA sequencing, qRT-PCR, and enzyme-linked immunosorbent assay. Macrophage phenotypes were determined using qRT-PCR, flow cytometry, and immunohistochemistry. Results NLRP7 protein levels, but not mRNA levels, were upregulated in CRC, and increased NLRP7 protein expression was associated with poor survival. NLRP7 promoted tumor cell proliferation and metastasis in vivo and in vitro and interacted with ubiquitin-specific protease 10, which catalyzed its deubiquitination in CRC cells. NLRP7 stability and protein levels in CRC cells were modulated by ubiquitination and deubiquitination, and NLRP7 was involved in the ubiquitin-specific protease 10 promotion of tumor progression and metastasis in CRC. K379 was an important lysine acceptor site that mediates NLRP7 ubiquitination in CRC cells. In CRC, NLRP7 promoted the polarization of pro-tumor M2-like macrophages by inducing the secretion of C-C motif chemokine ligand 2. Furthermore, NLRP7 promoted NF-κB nuclear translocation and activation of C-C motif chemokine ligand 2 transcription. Conclusions We showed that NLRP7 promotes CRC progression and revealed an as-yet-unidentified mechanism by which NLRP7 induces the polarization of pro-tumor M2-like macrophages. These results suggest that NLRP7 could serve as a biomarker and novel therapeutic target for the treatment of CRC.

Abstract
Background Colon cancer (CRC) was a malignant tumor and there were about 25% of patients with tumor metastasis at diagnosis stage. Chemotherapeutic agents for metastatic CRC patients were with great side effects and the clinical treatment results of advanced CRC were still not satisfactory. Human epidermal growth factor receptor 2 (HER2) is overexpressed in some CRC patients and is an effective target for CRC patient treatment. Anti-HER2 therapy had a beneficial role in the treatment of HER2-positive metastatic CRC with fewer side effects. CRC patients with BRAF mutations were resistant to HER2 antibodies treatment. Therefore, there was an urgent need to develop new therapeutic agents. Methods HER2 targeted nanoparticles (TPLNP) drug delivery system loading triptolide (TPL) were prepared and identified. The effects of TPLNP and free TPL on cell viability, targeting and cell cycle progression on HT29 (BRAF mutation) with HER2 overexpression, were evaluated by Cell Counting Kit-8 (CCK8), Fluorescence Activating Cell Sorter (FACS) and immunofluorescence methods, respectively. The anti-tumor efficacies of TPLNP were evaluated in subcutaneous xenograft model of colon cancer and the survival rate, tumor volume, liver and kidney indexes of tumor-bearing mice were measured. Results TPLNP was small in nanosize (73.4±5.2nm) with narrow size distribution (PDI=0.15±0.02) and favorable zeta potential (pH=9.6, zeta potential: −57.3±6.69mV; pH=7.0, zeta potential: −28.7±5.1mV; pH=5.6, zeta potential: −21.1±4.73mV). Comparing with free TPL treatment group, TPLNP developed stranger colon cancer-killing efficiency in a dose- and time-dependent manner detected with CCK8 method; achieved good in vitro colon cancer targeting detected with flow cytometry and immunofluorescence experiments; enhanced more HT29-HER2 apoptosis and induced more cell cycle arrested in G1-S phase detected with FACS in vitro. As for in vivo antitumor response, TPLNP remarkably inhibited the growth of colon cancer in the colon cancer xenograft model, significantly improved the survival rate and did not exhibit significant liver and kidney toxicity in contrast with free TPL in vivo. Conclusion TPLNP was effectively against colon cancer with HER2 overexpression and BRAF mutation in pre-clinical models. In summary, the TPLNP appeared to be a promising treatment option for CRC in clinical application based on improved efficacy and the favorable safety profile.

Abstract
BACKGROUND The clinical effect of endoscopic submucosal dissection (ESD) in the treatment of early esophageal squamous cell carcinoma (EESCC) is widely recognized. However, the long-term treatment outcome of simultaneous ESD for multiple EESCC currently remained unknown. Hence, this study was aimed at further evaluating the long-term outcome of simultaneous ESD for synchronous multiple EESCC by comparing with ESD for single EESCC. METHODS Consecutive patients who underwent ESD for EESCC from June 2008 to June 2018 were included. Propensity score-matched analysis was used to compensate for the differences in age, sex, tumor location, tumor size, and tumor invasion depth between simultaneous and single ESD groups. Treatment outcomes including en bloc resection rate, curative resection rate, complication rate, and long-term outcomes including overall survival (OS), recurrence-free survival (RFS), metachronous recurrence were compared between the 2 groups after matching. RESULTS The propensity score-matched analysis included 332 lesions (166 patients) and 332 lesions (332 patients) in simultaneous and single ESD groups, respectively. Among all the outcomes, en bloc resection, curative resection, 5-year OS, and 5-year RFS rates were comparable. Complications were more common in the simultaneous ESD group (15.06% vs. 9.64%, P = 0.073). The 5-year metachronous recurrence rates were significantly high in the simultaneous ESD groups (24.28% vs. 6.99%). CONCLUSIONS Simultaneous ESD is an effective and safe methodology for synchronous multiple EESCC; it also reduces hospital stay and medical expenses. The risk of metachronous recurrence is higher for patients with synchronous multiple EESCC; thus, more intensive strategies are required.

Abstract
Background The use of a self-expandable metallic stent (SEMS) as a bridge to surgery has increased for patients with obstructing colorectal cancer. However, relatively few reports have compared SEMS as a bridge to elective surgery for acute malignant obstruction of the right-sided colon (MORC) vs. emergency surgery (ES). This study aimed to evaluate the benefits of elective surgery after SEMS placement vs. ES for patients (including stage IV cases) with acute MORC. Methods Patients with acute MORC who underwent radical resection for a primary tumour from July 2008 to November 2016 at Zhongshan Hospital of Fudan University were retrospectively enrolled. Postoperative short-term outcomes, progression-free survival (PFS), and overall survival (OS) were compared between the SEMS and ES groups. Results In total, 107 patients with acute MORC (35 in the SEMS group and 72 in the ES group) were included for analysis. The Intensive Care Unit admission rate was lower (11.4% vs. 34.7%, P = 0.011), the incidence of complications was reduced (11.4% vs. 29.2%, P = 0.042), and the postoperative length of hospitalisation was significantly shorter (8.23 ± 6.50 vs. 11.18 ± 6.71 days, P = 0.033) for the SEMS group. Survival curves showed no significant difference in PFS (P = 0.506) or OS (P = 0.989) between groups. Also, there was no significant difference in PFS and OS rates between patients with stage II and III colon cancer. After colectomy for synchronous liver metastases among stage IV patients, the hepatectomy rates for the SEMS and ES groups were 85.7% and 14.3%, respectively (P = 0.029). The hazard ratio for colectomy alone vs. combined resection was 3.258 (95% CI 0.858–12.370; P = 0.041). Conclusion Stent placement offers significant advantages in terms of short-term outcomes and comparable prognoses for acute MORC patients. For synchronous liver metastases, SEMS placement better prepares the patient for resection of the primary tumour and liver metastasis, which contribute to improved survival.

Abstract
BACKGROUND Standard treatment for nonampullary duodenal tumors has not yet been established. In case of tumors originated from the muscularis propria (MP) layer and adherent to the serosa layer, the lesions can not be completely removed by ESD. However, with the development of the endoscopic suture technique, endoscopic full-thickness resection (EFTR) of duodenal subepithelial lesions has become possible. METHODS We retrospectively analyzed 32 patients with nonampullary duodenal subepithelial lesions who underwent EFTR between February 2012 and January 2017. The suturing method, complications that occurred during and after the operations, perioperative management, tumor characteristics, and pathological findings were analyzed in all patients. RESULTS The complete resection rate was 100%; all patients successfully received EFTR except for one patient who required conversion to open surgery. Severe abdominal pain was observed after the operation in one patient who then received laparoscopic exploration, and the possibility of delayed perforation was considered. Another patient showed a decline in blood oxygen saturation (SO2) and was transferred to the intensive care unit (ICU) for further management. Delayed bleeding and fistula were not observed. All patients achieved complete remission. CONCLUSION EFTR is a safe, minimally invasive treatment modality that ensures complete eradication of the duodenal subepithelial lesions.

Abstract
Objective: Synchronous multiple primary early esophageal cancers (SMPEEC) are rare and aggressive. Early detection of esophageal cancer can improve survival rate. Endoscopic submucosal dissection (ESD) is a minimally invasive endoscopic treatment of early esophageal cancers. However, ESD for SMPEEC is little known. We aimed to clarify the clinical outcomes of simultaneous ESD treating SMPEEC. Methods: We retrospectively reviewed the medical data of 34 patients, who underwent ESD for SMPEEC at Endoscopy Center of Zhongshan Hospital, Fudan University, between May 2013 and December 2014. The data of lesion size, histopathology, en bloc resection, curative resection, complication, and tumor local recurrence were analyzed. Results: Among 34 patients, 67 lesions were removed simultaneously in 33 cases; 2 lesions were removed in 2 operations for 1 case. For the simultaneous resection, the en bloc rate was 97.01% (65/67) and the curative resection rate was 92.54% (62/67). Postoperative stricture occurred in two cases and delayed bleeding occurred in one case. There was one local recurrence, no metastasis or procedure-related death. Conclusions: Simultaneous ESD as a treatment for SMPEEC is technically feasible, benefited from reducing hospitalization time and medical expenses. For the cases with risk factors of complications, simultaneous ESD needs to be avoided.

Abstract
Objective: To evaluate the safety and efficacy of dental floss traction-assisted endoscopic submucosal dissection (DFS-ESD) for rectal neuroendocrine neoplasm (NEN). Methods: A retrospective cohort study was performed. Clinical data of rectal NEN patients undergoing ESD at Endoscopy Center of Zhongshan Hospital, Fudan University from January 2016 to December 2017 were retrospectively analyzed. Inclusion criteria: 1) age of 18 to 80 years old; 2) maximal diameter of lesions <1.5 cm; 3) tumor locating in the submucosa without invasion into the muscularis propria; 4) no enlarged lymph nodes around bowel and in abdominal cavity; 5) ESD requested actively by patients. A total of 37 patients were enrolled, including 23 male and 14 female cases with mean age of (56.0±11.3) years. All the lesions were single tumor of stage T1, and the mean size was 0.8±0.2(0.5-1.2) cm. Postoperative pathology revealed all samples as neuroendocrine tumors (NET). Seventeen patients received DFS-ESD treatment (DFS-ESD group) and 20 patient received conventional ESD treatment (conventional ESD group). In DFS-ESD group, after the mucosa was partly incised along the marker dots, the endoscopy was extracted, and the dental floss was tied to one arm of the metallic clip. When the endoscope was reinserted, the hemoclip was attached onto the incised mucosa; another hemoclip was attached onto normal mucosa opposite to the lesion in the same way. The submucosa was clearly exposed with the traction of dental floss and the resection could proceed. The conventional ESD group received the traditional ESD operation procedure. The operation time, modified operation time (remaining time after excluding the assembly time of dental floss traction in DFS-ESD group), en bloc resection rate, R0 resection rate, morbidity of operative complication, recurrence and metastasis were compared between two groups. Results: The average tumor size was (0.8±0.2) cm in DFS-ESD group and (0.7±0.2) cm in conventional ESD group (t=0.425, P=0.673). According to postoperative pathological grading of rectal neuroendocrine neoplasm, 13 were G1 and 4 were G2 in DFS-ESD group, while 17 cases were G1 and 3 cases were G2 in conventional ESD group without significant difference (P=0.680). There were no significant differences in baseline data between in the two groups (all P>0.05). All the basal resection margins were negative, the en bloc resection rate was 100% and the R0 resection rate was 100%. Pathological results showed tumor tissue close to the burning margin in 5 cases of conventional ESD group and in 2 cases of DFS-ESD group (P=0.416). The operation time was (17.9±6.6) minutes in conventional ESD group and (14.7±3.3) minutes in DFS-ESD group (t=1.776, P=0.084). The modified operation time of DFS-ESD group was (11.9±2.8) minutes, which was significantly shorter than (17.9±6.6) minutes in conventional ESD group (t=3.425, P=0.002). The hospital stay was (2.3±0.6) days and (2.0±0.5) days in conventional ESD group and DFS-ESD group, respectively, without significant difference (t=1.436, P=0.160). No patient was transferred to surgery, and no delayed bleeding or perforation occurred in either group. There was no recurrence or primary tumor-related death, and all the patients recovered well during a follow-up period of 14(1-24) months. Conclusion: Dental floss traction-assisted ESD for rectal neuroendocrine neoplasm can simplify operation and ensure negative basal margin.

Abstract
BACKGROUND Gastric small submucosal tumors (SMTs) are becoming increasingly common. However, the fundus of stomach is regarded as a difficult area for endoscopic resection (ER). In this study, we investigated the efficacy, safety, and long-term outcomes of ER for small SMTs of the gastric fundus in a large series of patients, research that was previously lacking. METHODS 537 consecutive patients with SMTs no more than 20 mm in diameter, occurring in the gastric fundus and originating from the muscularis propria layer, which were treated with endoscopic submucosal excavation or endoscopic full-thickness resection (EFTR) were included in this retrospective study at Zhongshan Hospital of Fudan University from January 2013 to September 2016. Clinicopathological, endoscopic, and follow-up data were collected and analyzed. RESULTS En bloc resection was achieved in 100% of patients, and complete resection was achieved for 530 (98.7%) lesions. Although the total rate of complications was 9.3%, few serious adverse events occurred in only three (0.6%) patients, including major pneumoperitoneum, major hydrothorax, and bleeding. Unlike lager tumor sizes and longer procedure times, endoscopist experience had a positive impact on decreasing the likelihood of complications. Based on statistical analysis, tumors with greater size near the cardia, which were treated by EFTR, were the significant contributors to longer operative times. A median follow-up of 32 months was available, and all patients were free from local recurrence or distant metastasis during the study period. CONCLUSIONS Although the gastric fundus presents technical difficulties, ER is effective for the resection of small gastric SMTs with a high complete resection rate and rare serious adverse events.

Abstract
BACKGROUND According to the Japanese Esophageal Society (JES) guidelines, early esophageal squamous cell carcinoma (SCC) involving the muscularis mucosae (M3) or upper submucosal (SM1) layers are relative indications for endoscopic submucosal dissection (ESD). Additional esophagectomy or chemoradiotherapy is recommended for patients with relative indications after evaluation. However, elderly patients (≥ 60 years) with relative indications in China often refuse additional treatment because of the debilitating side effects. The aim of this study was to evaluate the long-term outcomes of elderly patients with relative indications who did not undergo additional treatment after ESD. METHODS Data from elderly patients with relative indications who underwent ESD for early esophageal SCC between January 2008 and December 2013 were reviewed retrospectively. Stricture and recurrence, and 5-year progression-free survival (PFS) and overall survival rates were compared with patients with absolute indications for ESD. RESULTS 158 elderly patients were included and analyzed (89 in the absolute indications group and 69 in the relative indications group). The baseline characteristics were balanced between the two groups. During 56 months (range 1 - 108) of follow-up, the postoperative stricture rates were similar in the absolute and relative indications groups (21.3 % vs. 31.9 %; P = 0.13). The hazard ratio (HR) for PFS in the absolute vs. the relative indications groups was 1.025 (95 % confidence interval [CI] 0.36 - 2.95; P = 0.96). The 5-year PFS rates were 90.5 % (95 %CI 83.44 - 97.56) and 90.8 % (95 %CI 83.74 - 97.86) for the absolute and relative indications groups, respectively. The HR for overall survival in the absolute vs. the relative indications groups was 0.564 (95 %CI 0.13 - 2.52; P = 0.45). The 5-year overall survival rates were 96.6 % (95 %CI 92.88 - 100) and 95.6 % (95 %CI 90.70 - 100) for the absolute and relative indications groups, respectively. CONCLUSIONS Based on this study, regular follow-up without additional treatment may be considered as another choice for elderly patients with early esophageal SCC and relative indications after ESD.

Abstract
BACKGROUND Endoscopic full-thickness resection (EFTR) derived from endoscopic submucosal dissection has gradually been accepted and even promoted for the treatment of submucosal tumors (SMTs) originating from the muscularis propria (MP) layer. However, there are some difficulties when EFTR is used to treat MP lesions in the gastric fundus. This study intends to explore whether EFTR can be made simpler, safer, and more effective with the traction assistance of dental floss. METHODS The clinical data of patients (trial group) with lesions in the MP layer in the gastric fundus undergoing EFTR with traction assistance of dental floss at Zhongshan Hospital, in 2016, were reviewed retrospectively. The control group was matched with the trial group according to tumor size. The differences in tumor resection time, patient hospitalization time, and complication rate were evaluated. RESULTS There was no significant difference in the average age of the two groups, each of which comprised 24 cases (58.7 ± 11.8 years versus 56.6 ± 7.9 years, t = 0.663, P = .511). However, there was a statistically significant difference in the operative time between the two groups (10.8 ± 2.8 minutes versus 19.0 ± 4.7 minutes, t = 7.298, P < .05). There was no statistically significant difference in the length of the postoperative hospital stay (3.2 ± 0.5 days versus 3.2 ± 0.5 days, t = 0.291, P = .772). In the trial group, there were 19 cases of gastrointestinal stromal tumors (group 1) and 5 cases of leiomyoma. The control group had similar results. Neither group experienced postoperative delayed bleeding, perforation, or other complications. CONCLUSIONS When EFTR is used to treat SMTs originating from the MP in the gastric fundus, dental floss traction assistance can relieve the tumor boundary to simplify the surgical procedure and save the operation time.

Abstract
OBJECTIVE With the improvement of endoscopic diagnosis, the discovery rate of the synchronous multiple primary early cancers in esophagus and stomach is gradually increased, while the traditional surgery bringing serious damages. Endoscopic submucosal dissection (ESD) has become the first treatment option of early cancer in the digestive tract partly. This study intends to explore the feasibility, safety, and effectiveness of ESD in the treatment of the synchronous multiple early gastric cancer or precancerous lesions in the esophagus and stomach. METHODS From January 2008 to December 2016, data of 12 patients with early esophageal cancer and early gastric cancer treated by ESD in the Endoscopy Center of Zhongshan Hospital, Fudan University were reviewed. We analyzed the patient's history, the size of esophageal and gastric lesions, pathological results, the results of complete or curative resection, and so on. RESULTS Among the 12 patients described in this study, all were diagnosed with synchronous multiple primary early cancers in the esophagus and stomach. Lesions were removed by ESD in 10 cases at the same time and were removed by stage in 2 cases. The complete resection rate was 100% (24/24), and the curative resection rate was 100% (24/24). Postoperative esophageal stricture occurred in 2 cases, which improved after dilation. Median follow-up time was 30 (8-115) months, when 9 patients survived and 3 patients died. However, the cause of death was not associated with treatment of this disease. CONCLUSION ESD is a minimally invasive endoscopic surgery, which can be used as a method of treating synchronous multiple primary early cancers in the esophagus and stomach.

Abstract
The molecular mechanisms underlying colorectal cancer (CRC) development remain elusive. In this study, we examined the miRNA and mRNA expressions in the adenoma-carcinoma sequence (ACS), a critical neoplastic progression in CRC development. We found that miR-137 was down-regulated in all adenoma and carcinoma tissues. Low miR-137 levels were correlated negatively with tumor progression and metastasis. Then we identified the inhibition effect of the miR-137 in CRC development, both in CRC cell lines and mouse models. MiR-137 was shown to control CRC cell proliferation, colony formation, migration and invasion and to control tumor growth and metastasis. We further confirmed the negative association between miR-137 and c-Met expression and thus validated this important oncogene as the target of miR-137 in CRC. In addition, we found a DNA methyl-CpG-binding protein, Mecp2, was up-regulated in ACS tissues via mRNA sequencing. Further experiment showed that miR-137 expression in CRC was subjected to epigenetic regulation mediated by Mecp2. We also confirmed c-Met expression can be up-regulated by silencing of miR-137 and suppressed by coexpression of Mecp2 and miR-137. These findings highlight the critical role of miR-137-c-Met nexus in CRC development and reveal Mecp2-regulated epigenetic silence causes the downregulation of miR-137 in colorectal adenoma and carcinoma.

Abstract
AIM: To determine the feasibility and effectiveness of endoscopic resection for the treatment of colorectal granular cell tumors (GCTs).
METHODS: This was a retrospective study performed at a single institution. From January 2008 to April 2015, we examined a total of 11 lesions in 11 patients who were treated by an endoscopic procedure for colorectal GCTs in the Endoscopy Center, Zhongshan Hospital of Fudan University, Shanghai, China. Either endoscopic mucosal resection or endoscopic submucosal dissection (ESD) was performed by three surgeons with expertise in endoscopic treatment. The pre- and post-operative condition and follow-up of these patients were evaluated by colonoscopy and endoscopic ultrasonography (EUS).
RESULTS: Of these 11 lesions, 2 were located in the cecum, 3 were in the ileocecal junction, 5 were in the ascending colon, and 1 was in the rectum. The median maximum diameter of the tumors was 0.81 cm (range 0.4-1.2 cm). The en bloc rate was 100%, and the complete resection rate was 90.9% (10/11). Post-operative pathology in one patient showed a tumor at the cauterization margin. However, during ESD, this lesion was removed en bloc, and no tumor tissue was seen in the wound. No perforations or delayed perforations were observed and emergency surgery was not required for complications. All patients were followed up to May 2015, and none had recurrence, metastasis, or complaints of discomfort.
CONCLUSION: Endoscopic treatment performed by endoscopists with sufficient experience appears to be feasible and effective for colorectal GCTs.
