Abstract
BACKGROUND It remains unclear whether addition of docetaxel to the combination of a platinum and fluoropyrimidine could provide more clinical benefits than doublet chemotherapies in the perioperative treatment for locally advanced gastric/gastro-esophageal junction (LAG/GEJ) cancer in Asia. In this randomized, phase 2 study, we assessed the efficacy and safety of perioperative docetaxel plus oxaliplatin and S-1 (DOS) versus oxaliplatin plus S-1 (SOX) in LAG/GEJ adenocarcinoma patients. METHODS Patients with cT3-4 Nany M0 G/GEJ adenocarcinoma were randomized (1:1) to receive 4 cycles of preoperative DOS or SOX followed by D2 gastrectomy and another 4 cycles of postoperative chemotherapy. The primary endpoint was major pathological response (MPR). RESULTS From Aug, 2015 to Dec, 2019,154 patients were enrolled and 147 patients included in final analysis, with a median age of 60 (26-73) years. DOS resulted in significantly higher MPR (25.4 vs. 11.8%, P = 0.04). R0 resection rate, the 3-year PFS and 3-year OS rates were 78.9 vs. 61.8% (P = 0.02), 52.3 vs. 35% (HR 0.667, 95% CI: 0.432-1.029, Log rank P = 0.07) and 57.5 vs. 49.2% (HR 0.685, 95% CI: 0.429-1.095, Log rank P = 0.11) in the DOS and SOX groups, respectively. Patients who acquired MPR experienced significantly better survival. DOS had similar tolerance to SOX. CONCLUSIONS Perioperative DOS improved MPR significantly and tended to produce longer PFS compared to SOX in LAG/GEJ cancer in Asia, and might be considered as a preferred option for perioperative chemotherapy and worth further investigation.

Abstract
BACKGROUND AND AIMS Endoscopic hand-suturing (EHS) has been preliminarily demonstrated to be effective in closing defects after endoscopic submucosal dissection (ESD), but it is not easily performed. We proposed a strategy combining EHS with clips (EHS-Clips) and explored its effectiveness in closing rectal defects after ESD or ESD with myectomy (ESD-ME). METHODS In this observational study, data from patients with rectal defects closed using EHS-Clips were reviewed. EHS-Clips refers to a strategy where defects are sutured as much as possible by EHS first, with clips being used to close the remaining parts of defects that cannot be completely sutured. The primary endpoints included complete closure rate, delayed bleeding (DB) rate, and sustained closure rate. Logistic regression analyses were performed to identify risk factors for the sustained closure. RESULTS All 49 (100%) defects (42 ESD defects and 7 ESD-ME defects) were completely closed through the strategy of EHS-Clips, with 35 (71.4%) through EHS alone and 14 (28.6%) through EHS and additional clips. No patients experienced DB. Thirty-six (73.5%) defects remained sustained closure on postoperative days 3 to 5 (73.8% for ESD defects vs 71.4% for ESD-ME defects). The multivariate analyses identified a stitch margin of ≥5 mm (hazard ratio, 0.313; 95% confidence interval, 0.023-0.781; P = .009) as the only independent advantage factor for the sustained closure. CONCLUSIONS EHS-Clips can be used to effectively close the rectal defects after ESD or ESD-ME and prevent DB. Complete suture with a stitch margin of ≥5 mm may achieve more reliable sustained closure.

Abstract
BACKGROUND The personalized treatments of T1 colorectal cancer (CRC) remains controversial. We compared the long-term outcomes of T1 CRC patients after endoscopic resection (ER) and surgery, and evaluated the risk factors for the long-term prognosis. METHODS T1 CRCs after resection at the Cancer Hospital, Chines Academy of Medical Sciences from June 2011 to November 2021 were reviewed. High-risk factors included positive resection margin, poor differentiation, deep submucosal invasion (DSI ≥ 1000 μm), lymphovascular invasion and intermediate/high tumor budding. Comparative analyses were conducted based on three treatment methods: follow-up after ER (Group A), additional surgery after ER (Group B) and initial surgery (Group C). The primary endpoints included recurrence-free survival (RFS) and overall survival (OS). Cox proportional hazard regression models were constructed to identify risk factors for RFS and OS. RESULTS A total of 528 patients were enrolled (173 patients in Group A, 102 patients in Group B, 253 patients in Group C). The 3-year RFS, 5-year RFS, 3-year OS, and 5-year OS rates were 96.7%, 94.7%, 99.1%, and 97.8%, respectively. In the absence of other high-risk factors, RFS (P = 0.321) and OS (P = 0.155) of patients with DSI after ER were not inferior to those after surgery. Multivariate analyses identified sex (HR 0.379; 95% CI 0.160-0.894), Charlson comorbidities index (CCI) (HR 3.330; 95% CI 1.571-7.062), margin (HR 8.212; 95% CI 2.325-29.006), and budding (HR 3.794; 95% CI 1.686-8.541) as independent predictive factors of RFS, and identified CCI (HR 10.266; 95% CI 2.856-36.899) as an independent predictive factor of OS. CONCLUSION The long-term outcomes of ER are comparable to those of surgery in T1 CRC patients with DSI when other high-risk factors are negative. Resection margin, tumor budding, sex, and CCI may be the most important long-term prognostic factors for T1 CRC patients.

Abstract
INTRODUCTION Adjuvant radiotherapy is recommended for pT1b esophageal squamous cell cancer (ESCC) after endoscopic submucosal dissection (ESD). However, it is unclear whether additional radiotherapy can improve patient survival. This study aimed to evaluate the efficacy of adjuvant radiotherapy after ESD for pT1b ESCC. METHODS This was a multicenter, cross-sectional study involving 11 hospitals in China. Between January 2010 and December 2019, patients with T1bN0M0 ESCC treated with or without adjuvant radiotherapy after ESD were included. Survival between groups was compared. RESULTS Overall, 774 patients were screened, and 161 patients were included. Forty-seven patients (29.2%) received adjuvant radiotherapy after ESD (RT group) and 114 (70.8%) underwent ESD alone (non-RT group). There were no significant differences in overall survival (OS) and disease-free survival (DFS) between the RT and non-RT groups. Lymphovascular invasion (LVI) was the only prognostic factor. In the LVI+ group, adjuvant radiotherapy significantly improved survival (5-year OS: 91.7% vs 59.5%, P = 0.050; 5-year DFS: 92.9% vs 42.6%, P = 0.010). In the LVI- group, adjuvant radiotherapy did not improve survival (5-year OS: 83.5% vs 93.9%, P = 0.148; 5-year DFS: 84.2% vs 84.7%, P = 0.907). The standardized mortality ratios were 1.52 (95% confidence interval 0.04-8.45) in the LVI+ group with radiotherapy and 0.55 (95% confidence interval 0.15-1.42) in the LVI- group without radiotherapy. DISCUSSION Adjuvant radiotherapy could improve survival in pT1b ESCC with LVI+ other than LVI- after ESD. Selective adjuvant radiotherapy based on LVI status achieved survival rates similar to those of the general population.

Abstract
BACKGROUND Although endoscopic screening for esophageal cancer has been performed in high-risk areas in China for decades, there is limited and inconsistent evidence regarding the starting age for individuals participating in screening. The aim of this study is to investigate the optimal starting age of esophageal cancer screening. METHODS This study is based on a multicenter prospective cohort consisting 338,017 permanent residents aged 40-69 years in six high-risk areas of esophageal cancer in China. The participation rate, detection rate, hazard ratios (HRs), cumulative incidence and mortality and number needed to screen (NNS) were calculated in each age group. Screening burden, benefit and risk were compared among screening strategies with different initiation ages to explore the optimal starting age for population-based screening in high-risk areas. RESULTS Individuals aged 50-69 had a higher participation rate, a higher detection rate and improved screening effectiveness than those aged 40-49. The endoscopic screening had no significant effect on reducing the incidence of esophageal cancer in individuals under 55 and mortality in individuals under 45. Increasing the starting age to 50 years reduced the screening demand and NNS by 40% and 55%, and resulted in 12% of detectable positive cases, 16% of preventable incident cases, and 14% of preventable deaths being missed. CONCLUSIONS Postponing the starting age of endoscopic screening to 50 years might yield a more-favorable balance between screening benefit and burden in high- risk areas with limited resources.

Abstract
Background It remains controversial whether endoscopic submucosal dissection (ESD) is still appropriate for circumferential superficial esophageal squamous cell neoplasms (SESCN), and few studies compared the short-term and long-term outcomes of ESD with radical surgery. Methods A total of 140 patients with SESCN who underwent ESD or surgery between February 2014 and October 2021 were retrospectively reviewed. The characteristics of patients, operative time, postoperative complications, overall survival (OS), recurrence-free survival (RFS), and quality of life (QOL) were compared between the ESD and surgery groups. The effect of different methods to prevent esophageal stenosis after ESD were analysed. Results Drinking, family history of cancer, macroscopic type, and intrapapillary capillary loop (IPCL) type were independent risk factors for deep submucosal invasion (SM ≥ 200 μm). Smoking and IPCL type were independent predictive factors for angiolymphatic invasion. The average operative time of ESD was significantly shorter than that of surgery (174.5 ± 51.16 min vs. 255.9 ± 88.18 min, p < 0.001). The incidence of perioperative complications in ESD group was significantly lower than that in surgery group (5.5% vs. 19.4%, p = 0.015). The ESD group had significantly better functional scale scores for emotional functioning, cognitive functioning, and global health status, and lower rates of pain, dyspnoea, insomnia, appetite loss, diarrhoea, reflux, and trouble with taste than the surgery group. No significant difference in OS and RFS between ESD and surgery group. Conclusions ESD can significantly shorten the operative time and reduce perioperative complications. Additionally, on the premise of using appropriate measures to prevent postoperative stenosis, ESD can be the first choice for the treatment of SESCN, which could provide better QOL, and the long-term prognosis of ESD is no less than that of surgery.

Abstract
Diverticulosis is a commonly acquired disease of the lower gastrointestinal tract, which may be associated with significant morbidity and adverse effects on quality of life. Although several national guidelines focused on the treatment of diverticulosis, multiple controversies remained regarding the disease management of diverticulosis. For some controversial issues, such as the role of antibiotics in mild diverticulitis, when and how to operate on patients with acute diverticulitis, there is no conclusion yet. To our knowledge, this is the first report of endoscopic therapy for anastomotic diverticulitis caused by stercorolith incarceration. In the current case, a 49-year-old woman complained of recurrent subumbilical pain without obvious inducement for half a year. Colonoscopy showed anastomotic diverticulum combined with stercorolith incarceration. After local inflammation relieved by conservative treatment, the patients received endoscopic mucosal incision and lithotomy. Then the diverticulum was closed with titanium clips. The abdominal pain of patient was completely relieved, and the reexamination of colonoscopy showed that the wound healed well after 1 year of follow-up. This case suggests that for anastomotic diverticulitis caused by stercorolith incarceration, endoscopic therapy can remove the stimulation factors better and avoid the recurrence and progression of the disease compared with conservative treatment. Moreover, endoscopic therapy achieves the maximum in minimally invasive surgery and reduces complications and surgical costs compared with radical surgery.

Abstract
(1) Background: Endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) in the remnant stomach or gastric tube is not yet widespread and few studies have compared the short-term and long-term outcomes with radical surgery. (2) Methods: A total of 73 consecutive patients with EGC in the remnant stomach or gastric tube who underwent ESD or radical surgery between October 2009 and October 2020 were retrospectively analyzed in this study. Baseline characteristics, post-operative complications, quality of life (QOL), recurrence rate, overall survival (OS) and disease-free survival (DFS) were compared between the ESD and surgery groups. (3) Results: Among the 73 patients with EGC in the remnant stomach or gastric tube, 48 (65.8%) underwent ESD and 25 (34.2%) underwent surgery. The operation time (p = 0.000) and post-operative hospital stay (p = 0.002) of the ESD group were significantly shorter than those in the surgery group. The incidence of post-operative complications in the ESD group was significantly lower than that in surgery group (p = 0.001). The ESD group had significantly better functional scale scores and lower rates of fatigue, pain, appetite loss, financial difficulties, dysphagia, eating restrictions, hair loss, and poor body image than the surgery group. There was no significant difference in OS or DFS between the ESD and surgery groups (p = 0.124 and 0.344, respectively). (4) Conclusion: ESD can significantly shorten the operation time and hospital stay, reduce surgical complications, and provide better QOL for patients with EGC in the remnant stomach or gastric tube, and its long-term prognosis is no shorter than that of radical surgery.

Abstract
Solitary rectal ulcer syndrome (SRUS) is a benign and chronic disorder well known in young adults that is characterized by a series of symptoms such as rectal bleeding, copious mucus discharge, prolonged excessive straining, perineal and abdominal pain, a feeling of incomplete defecation, constipation and, rarely, rectal prolapse. The etiology of this syndrome remains obscure, and the diagnosis is easily confused with that of other diseases, contributing to difficulties in treatment. We present a case of a 37-year-old male with a nonulcerated rectal lesion grossly resembling a superficial depressed rectal cancer misdiagnosed in another hospital and describe its appearance on endoscopy and in the analysis of its pathological manifestations. The aim of this case report is to report an easily misdiagnosed case of SRUS, which needs to be distinguished from superficial rectal cancer, which should be educational for endoscopists.

Abstract
Objective: To investigate the relationship between psoriasis severity and clinical features in psoriatic arthritis (PsA). Methods: Patients were recruited from the Chinese REgistry of Psoriatic ARthritis (CREPAR) between December 2018 and June 2021, and data were collected including the baseline demographic characteristics, various clinical manifestations (including arthritis, nail disease, comorbidities), laboratory tests[including erythrocyte sedimentation rate(ESR), C-reactive protein (CRP)], health assessment questionnaire (HAQ). Body surface area (BSA) and psoriasis area and severity index (PASI) were selected for the tools of assessment of cutaneous psoriasis. Patients were divided to two groups, including the severe psoriasis group (BSA>10%) and the non-severe psoriasis group (BSA≤10%). Disease assessment included ankylosing spondylitis disease activity score (ASDAS), disease activity score 28 (DAS28) and disease activity in psoriatic arthritis (DAPSA). Results: 1 074 eligible patients with PsA were recruited, and 106 (9.9%) had severe psoriasis. Compared with non-severe psoriasis group, the severe psoriasis group had more peripheral joint involvement (including patients with ever or current peripheral arthritis, 94.3% vs. 85.6%), more polyarticular joint involvement (including patients with current peripheral arthritis, 74.0% vs. 58.2%), more axial joint involvement (51.4% vs. 39.9%), more nail disease (72.6% vs. 61.4%), more frequency of smoking (20.2% vs. 18.7%), and higher proportion of hypertension (23.4% vs. 14.4%). In addition, the severe psoriasis group had higher level of ESR [33(10, 70) mm/1h vs. 20(9, 38) mm/1h] and CRP [18.6(5.0, 60.8) mg/L vs. 7.0(2.4, 18.1) mg/L], higher values of DAS28-ESR (4.5±1.7 vs. 3.7±1.5), DAS28-CRP (4.2±1.5 vs. 3.4±1.4), ASDAS-ESR (3.5±1.4 vs. 2.6±1.2), and ASDAS-CRP(3.4±1.6 vs. 2.5±1.2), higher scores of HAQ [0.6(0.1, 1.0) vs. 0.3(0.0, 0.8)]. Conclusion: Patients with PsA with severe psoriasis bore a heavier disease burden. Therefore, clinicians were supposed to pay more attention to them. In addition to skin lesions, they should also focus on examination of other clinical manifestations, such as joints and nails.

Abstract
4031 Background: The optimal perioperative chemotherapy of locally advanced gastric or gastro-esophageal junction (G/GEJ) cancer has not been established in Asia, though FLOT was considered as standard therapy in Europe. Therefore, we aimed to assess efficacy and safety of DOS versus SOX as perioperative treatment in patients with locally advanced G/GEJ cancer in this study. Methods: This was a single center, open-label, randomized, phase 2 study. Eligible pts were aged ≥18 years with histologically diagnosed HER2 negative cT3-4 Nany M0 G/GEJ (Siewert II/III type) adenocarcinoma. Pts were randomized (1:1) to receive either 4 preoperative and 4 postoperative cycles of DOS (docetaxel 60mg/m2 D1, oxaliplatin 100mg/m2 D1, S-1 40-60mg bid D1-14 depending on body surface area (BSA), Q3W) or SOX (oxaliplatin 130mg/m2 D1, S-1 40-60mg bid D1-14 depending on BSA, Q3W). Pts underwent D2 gastrectomy after preoperative treatment. The primary endpoint was major pathological response (MPR) analyzed in the modified intention to treat (mITT) population according to Becker TRG criteria. Secondary endpoints included the 3-year progression free survival (PFS), the 3-year overall survival (OS), pathological complete response, R0 resection rate and safety. Results: From Aug, 2015, to Dec, 2019, 154 pts were enrolled, 7 pts withdrew consent, 147 pts were included as mITT population (DOS 71; SOX 76). 80.3% and 67.1% of the pts in the DOS and SOX groups accepted surgery respectively. More pts achieved MPR (25.4% vs. 11.8%, p = 0.035) and R0 resection (78.9% vs. 61.8%, p = 0.024) in the DOS group than the SOX group. With a median follow-up of 42.4 months, the 3-year PFS and the 3-year OS were 52.3% vs. 35% (p = 0.065, HR 0.667, 95%CI 0.432-1.029) and 57.5% vs. 49.2% (p = 0.114, HR 0.685, 95%CI 0.429-1.095) in the DOS and SOX groups, respectively. Pts who acquired MPR had a significant longer survival than non-MPR pts. The 3-year PFS were 89.4% vs. 38.6% (p < 0.001, HR 0.076, 95%CI 0.018-0.314). The 3-year OS were 100% vs. 50.1% (p = 0.008, HR 0.024, 95%CI 0.002-0.371). 56.1% and 60.8% of the pts completed at least 6 cycles of the perioperative chemotherapy in the DOS and SOX groups, respectively (p = 0.625). The most common grade ≥3 TRAEs included neutropenia (8.5% vs.10.5%), leucopenia (1.4% vs. 5.3%), thrombocytopenia (1.4% vs 15.8%, p = 0.002), anemia (1.4% vs. 3.9%) and diarrhea (1.4% vs. 2.6%). The incidence of grade 1-2 thrombocytopenia was also significant lower in the DOS group (15.5% vs. 31.6%, p = 0.022). No treatment-related deaths occurred. Conclusions: Perioperative DOS improved MPR significantly and tended to have better PFS compared with SOX in locally advanced G/GEJ cancer, might be regarded as a prefered option of perioperative chemotherapy. Clinical trial information: NCT02725424.

Abstract
Significant proof suggests an essential role played by the bile microbiota in biliary diseases. This study retrospectively analyzed the differences in biliary microbes among patients with perihilar cholangiocarcinoma (pCCA), distal cholangiocarcinoma (dCCA), pancreatic cancer (PC), and cholelithiasis (CH). Bile samples were obtained from 53 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP), and the bile microbiota was analyzed through 16S rRNA gene analysis and next-generation sequencing. Based on the results of linear discriminant analysis effect size (LEfSe), the top three biomarkers for pCCA at the genus level were Pseudomonas, Sphingomonas, and Halomonas; for dCCA were Streptococcus, Prevotella, and Halomonas; and for PC were Pseudomonas, Chloroplast, and Acinetobacter. The top five genera in the pCCA, dCCA, and PC groups showed predictive values with areas under the receiver operating characteristic curves of 91.56%, 95.56%, and 96.59%, respectively. The PICRUSt2 analysis outcomes displayed the diversities of fifteen pathways between the CH and pCCA groups, 22 pathways between the CH and dCCA groups, and eighteen pathways between the CH and PC groups. As this pilot study identified specific microbial bile markers for patients with CH, pCCA, dCCA, and PC, the clinical implications are vast. Further study focusing on distinct bacterial populations in bile will help differentiate biliary diseases.

Abstract
Background Local recurrence of esophageal squamous cell neoplasia (ESCN) and metachronous ESCN was associated with severe background esophageal multiple Lugol-voiding lesions (LVLs) even though the primary early ESCNs were treated with endoscopic resection (ER). The aim of this study is to explore the feasibility and effectiveness of combination treatments of ER and radiofrequency ablation (RFA) in patients with early ESCNs with synchronous multiple LVLs. Methods A total of 329 patients with early ESCNs and synchronous multiple LVLs received ER combined with RFA from September 2010 to September 2020. Clinical and pathological features and treatment outcomes were retrospectively reviewed using medical records. Factors associated with background esophageal multiple LVLs before combined treatment were analyzed. Results The proportion of complete response (CR) was 96.7% after primary RFA, while 90.3% patients achieved CR for the last endoscopic examinations regardless if inside or outside the treatment area (TA). Degeneration of background esophageal multiple LVLs occurred in 70.2% of patients. The grade of background esophageal multiple LVLs before combined treatment was closely related to gender, smoking, and drinking. The incidence of metachronous ESCNs outside the TA of ER and local recurrence in the TA of ER was 3.9% and 1.2%, respectively. Conclusions Prophylactic RFA treatment of multiple LVLs together with ER treatment of the primary ESCNs may be effective in reducing the incidence of metachronous ESCNs and local recurrence through improving the background esophageal mucosa.

Abstract
Important evidence indicates that the microbiota plays a key role in esophageal squamous cell carcinoma (ESCC). Here, paired saliva and brush specimens were obtained from 276 participants undergoing upper gastrointestinal endoscopic examination before or during screening for upper gastrointestinal (UGI) cancer. The esophageal microbiota was investigated by 16S rRNA gene profiling and next-generation sequencing. We observed that as the disease progressed, the α diversity in the saliva and cell brush samples decreased. Linear discriminant analysis effect size (LEfSe) results showed that in both the saliva and cell brush specimens, Granulicatella, Rothia, Streptococcus, Gemella, Leptotrichia and Schaalia were common biomarkers in patients with low-grade dysplasia, Lactobacillus was a common biomarker in patients with high-grade dysplasia, and Bosea, Solobacterium, Gemella, and Peptostreptococcus were common biomarkers in patients with esophageal cancer. The top 3 genera in the saliva and cell brush specimens had areas under the curve (AUCs) of 87.16 and 89.13%, respectively, to distinguish ESCC patients from normal people. The PICRUSt2 results identified in brush samples that patients with ESCC had decreased nitrate reductase functions. Our results suggest that future studies can focus on the function of the characteristic bacteria in ESCC.

Abstract
Background To explore the effects of smoking and drinking on the microbiota in the saliva and three segments of the esophagus (upper, middle, and lower) in healthy individuals. Methods Paired saliva and brush specimens were obtained from 76 participants who underwent upper gastrointestinal (UGI) endoscopic examination for UGI cancer screening. The esophageal microbiota was investigated by 16S rRNA gene profiling via next-generation sequencing. Results The saliva samples from non-smoking and non-drinking participants had a greater abundance of Neisseria, Prevotella, Porphyromonas, and Rothia, and lower levels of Streptococcus, Actinobacillus, and Haemophilus compared to the esophagus. There were no significant differences in the abundance of most bacterial genera in the upper, middle, and lower oesophagus. Similarly, in the saliva of patients who smoke and drink, there was a higher prevalence of Neisseria, Prevotella, Porphyromonas, Fusobacterium, and Rothia, and a lower prevalence of Streptococcus, Actinobacillus, and Haemophilus compared to the esophagus. There were no significant differences in the abundance of most genera in the upper, middle, and lower esophagus of patients with a history of drinking and smoking. There were slight differences in the microbiota between smoking and drinking individuals and non-smoking and non-drinking individuals. Conclusions This pilot study demonstrated microbial diversity at different taxonomic levels in the oral cavity and esophagus of non-drinking and non-smoking individuals, as well as healthy people who drink and smoke . There was a slight difference in the microbiota between non-drinking and non-smoking people and individuals with a history of drinking and smoking. These results suggested that oral or esophageal cancer caused by smoking and drinking may not be mediated by mechanisms that affect surface microorganisms.

Abstract
Background This research aimed at investigating the safety and efficacy of autologous esophageal mucosa (AEM) with polyglycolic acid (PGA) transplantation and temporary stent implantation (TSI) in preventing esophageal stenosis (ES) after early esophageal cancer (EC) surgery. Methods Between April 2019 and October 2020, patients scheduled for circumferential endoscopic submucosal dissection (ESD) were prospectively recruited. After ESD, autologous esophageal mucosal patches (MPs) were constructed on the absorbable PGA felt. Then, the felt was structured onto a covered metal mesh stent (CMMS) and attached to the ulcer surface. The stents were removed 6-8 weeks after the operation. The occurrence of ES and adverse events was observed and analyzed. Results Data from 25 patients were analyzed. In total, 14 patients (56%) had no stenosis during an average follow-up of 10.2 months, and 11 patients (44%) suffered strictures at a mean interval of 63.73 days after the ESD procedure. Stent migration occurred in 2 patients. No other complications, including perforations, bleeding, or wound infections, occurred. The median of endoscopic balloon dilatation (EBD) sessions was 2.16 (range, 0-14). There showed a higher post-ESD stricture rate in patients with lesions located in the middle-lower esophagus (P<0.05). More transplanted MPs may reduce the occurrence of ES. Conclusions AEM with PGA transplantation and TSI is a safe and effective approach of preventing ES and improving the life quality after circumferential ESD.

Abstract
BACKGROUND To observe and preliminarily evaluate the efficacy and safety of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) in the treatment of non-ampullary duodenal lesions (NADLs). METHODS This retrospective observational study included 84 patients who underwent endoscopic resection (ER) with non-ampullary duodenal lesions, between March 2010 and November 2020, at the Cancer Hospital of the Chinese Academy of Medical Sciences (Beijing, China). Data on patient demographics, therapeutic outcomes, and follow-up results were analyzed. RESULTS There were 44 patients undergoing EMR, and 40 patients accepting ESD. The overall en bloc resection rate was 98.8% (83/84). For the neoplastic lesions, the overall en bloc resection rate and curative rate were 98.5% (67/68) and 89.7% (61/68), respectively. The procedure-related bleeding and perforation rates were 2.4% and 10.7%, respectively. Univariate analysis results indicated that the main correlation factor of non-curative pathologic resection was tumor size (p = 0.004) and resection size (P < 0.01). There showed a higher curative rate in patients with tumors less than 25 mm in diameter. Multivariate logistic regression analyses determined that the tumor size (OR 0.935; 95% CI 0.878-0.995; P = 0.035) was associated with non-curative resection. No recurrences were observed in patients who had undergone a complete ER during a follow-up period of 42.8 months (range, 3-127 months). CONCLUSION Endoscopic resection is an effective, safe, and feasible treatment for non-ampullary duodenal lesions.

Abstract
OBJECTIVE The role of NEAT1 in cancers has been demonstrated. But the role of NEAT1 in cardiac hypertrophy still remains unknown. This study aimed to elucidate the specific function of long non-coding RNA (lncRNA) NEAT1 in cardiac hypertrophy and its underlying mechanism. PATIENTS AND METHODS In this study, the in vivo and in vitro cardiac hypertrophy models were constructed by transverse aortic coarctation (TAC) procedure in rats and phenylephrine (PE) induction in primary cardiomyocytes, respectively. The expression levels of NEAT1, microRNA-19a-3p, SMYD2, and cardiac hypertrophic markers were detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Cardiac hypertrophy was evaluated as calculating the surface area of hypertrophic cardiomyocyte by fluorescein isothiocyanate (FITC)-Phalloidin staining. Luciferase Reporter Gene Assay was conducted to detect the binding of NEAT1, SMYD2, and microRNA-19a-3p. RESULTS The results showed that NEAT1 and SMYD2 were highly expressed in myocardium of rats with cardiac hypertrophy and PE-induced primary cardiomyocytes, whereas microRNA-19a-3p was lowly expressed. Besides, NEAT1 overexpression markedly upregulated levels of the cardiac hypertrophic markers. Moreover, FITC-Phalloidin staining also revealed hypertrophic cardiomyocytes overexpressing NEAT1. On the contrary, microRNA-19a-3p overexpression reduced the cardiomyocyte surface area and downregulated the levels of the cardiac hypertrophic markers. As luciferase reporter gene assay demonstrated, NEAT1 and SMYD2 could bind to microRNA-19a-3p. Finally, the gain-of-function experiments were designed to verify whether NEAT1 exerted its functions in cardiac hypertrophy by modulating SMYD2 and microRNA-19a-3p. Furthermore, both microRNA-19a-3p overexpression or SMYD2 knockdown could inhibit and reduce the cardiomyocyte surface area, and downregulate the levels of the cardiac hypertrophic markers. CONCLUSIONS In summary, NEAT1 promotes the occurrence and progression of cardiac hypertrophy by upregulating SMYD2 by binding to microRNA-19a-3p.

Abstract
BACKGROUND The curative criteria after endoscopic submucosal dissection for early gastric carcinoma were updated by the Japanese Gastric Cancer Association. No study has shown promising results with endoscopic submucosal dissection for early adenocarcinoma of esophagogastric junction based on the new curative criteria. The purpose of this study was to validate clinical efficacy of the application of the curative criteria of the 5th edition Japanese gastric cancer treatment guidelines for early adenocarcinoma of esophagogastric junction after endoscopic submucosal dissection. METHODS Patients who underwent endoscopic submucosal dissection for Siewert type II adenocarcinoma between January 2013 and June 2018 were eligible for this study. Clinical and pathological features and treatment outcomes were retrospectively reviewed using medical records. RESULTS The success rate for en-bloc resection was 97.2% (172/177) and the curative resection rate was 71.2% (126/177). Additional endoscopic submucosal dissection or radical surgery was conducted in 10 patients (5.6%) who did not fulfil the curative resection criteria, while one patient with curative resection remedied with endoscopic submucosal dissection because of recurrence. According to eCura scoring system, 94 patients (53.1%) were categorized into eCura A, 34 patients (19.2%) into eCura B, 11 patients (6.2%) into eCura C-1, and 38 patients (21.5%) into eCura C-2. Five patients categorized as eCura C-2 underwent radical surgery, two of whom have lymph node metastasis. CONCLUSIONS Endoscopic submucosal dissection for early adenocarcinoma of esophagogastric junction that met the expanded criteria of the 5th edition Japanese gastric cancer treatment guidelines were acceptable and should be the standard treatment instead of surgical resection.

Abstract
Background Endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) are used to remove esophagogastric junction (EGJ) neoplasm. This study aimed to compare feasibility, safety, and effectiveness between ESD and EMR to help endoscopists choose treatment methods. Methods A total of 130 patients with EGJ neoplasm underwent endoscopic resection, including 52 patients with EMR and 78 patients with ESD. Cap-assisted EMR (EMRC) was performed with typical sequences. Larger lesions required removal in multiple pieces (i.e., piecemeal EMR). The ESD procedures were included that marking the periphery of the lesion, submucosa injected, circumferentially cutting and submucosal dissection. Resection time, adverse events, en bloc resection rate, R0 resection rate and recurrence rate were compared between the two groups. Results There were no significant differences in demographic characteristics or histopathological features between the two groups. Resection time was longer in the ESD group than in the EMR group (64.4±33.9 vs. 22.1±8.0 minutes; P<0.01). Adverse events were more common in the ESD group than in the EMR group (16.7% vs. 3.8%; P=0.03), including bleeding (7.7% vs. 3.8%), perforation (5.1% vs. 0%) and stenosis (5.1% vs. 0%). The en bloc resection rate and R0 resection rate were much higher in the ESD group than in the EMR group (98.7% and 92.3% vs. 23.1% and 23.1%, respectively; P<0.01). The 5-year overall survival rate and disease-free survival rate were 100% vs. 92.0% and 100% vs. 90.1% between the ESD and EMR groups, respectively (P=0.01 and P=0.01). The 5-year cancer-specific survival rate was 100% vs. 96.0% between the ESD and EMR groups (P=0.08). The recurrence rate was lower in the ESD group than in the EMR group (0% vs. 9.6%; P=0.01). Conclusions ESD is an acceptable first-line endoscopic treatment for type II EGJ neoplasm, however, it is time-consuming and has a higher rate of adverse events. Furthermore, EMR is a safe and alternative technique, particularly when EMR could achieve en bloc resection.

Abstract
Background The incidence of metachronous early cancer or precancerous lesions (MECPL) emerging at the anastomotic site (AS) after curative surgical resection of colorectal cancer (CRC) is so low that few study have been conducted to explore the clinical characteristics, diagnosis and treatment of these lesions. Endoscopic submucosal dissection (ESD) is technically difficult for these lesions because of the presence of severe fibrosis and AS. The aim of this study was to explore the safety and efficacy of ESD for MECPL emerging at the AS after curative surgical resection of CRC. Methods The data used in the analysis were retrospectively collected from CICAMS in Beijing China between January 2013 and May 2019 and from all the patients who underwent ESD for MECPL emerging at the AS after curative surgical resection of CRC. The rates of en bloc resection (ER), complete resection (CR), curative resection (CuR) and incidence of complications were analyzed by SPSS software. Results A total of 11 patients were included. The rates of ER, CR and CuR were 63.6%, 54.5% and 54.5%, respectively. No additional surgery was performed, and no recurrences were found. Bleeding occurred in only one case and there was no perforation after the operation. Conclusions Overall, ESD is safe and effective in the treatment of MECPL emerging at the AS after curative surgical resection of CRC. Especially for patients with anastomotic recurrence close to anal margin, this method can avoid the risks of reoperation and improve the rate of anal preservation.

Abstract
OBJECTIVE To clarify whether microRNA-494-3p could exert an anti-inflammation effect by suppressing the expression of toll-like receptor 6 (TLR6), thus inhibiting the development of sepsis. PATIENTS AND METHODS Plasma levels of microRNA-494-3p and TLR6 in sepsis patients and healthy controls were determined by quantitative real-time polymerase chain reaction (qRT-PCR). Diagnostic potential of microRNA-494-3p in sepsis was evaluated by receiver operating characteristic (ROC) curve. In vitro macrophage inflammation model was established by lipopolysaccharides (LPS) induction in RAW264.7 cells. Expression levels of microRNA-494-3p, TLR6 and tumor necrosis factor-α (TNF-α) in LPS-induced RAW264.7 cells were observed. After transfection of microRNA-494-3p mimics in LPS-induced RAW264.7 cells, mRNA and protein levels of TNF-α were determined by qRT-PCR and Western blot, respectively. Meanwhile, cytoplasmic and nuclear fractions of nuclear factor-kappa B (NF-κB) p65 were respectively extracted for evaluating nuclear translocation of NF-κB p65 by Western blot analysis. Dual-luciferase reporter gene assay was performed to verify the binding between microRNA-494-3p and TLR6. Finally, rescue experiments were carried out to elucidate whether microRNA-494-3p attenuated sepsis-induced inflammation through degrading TLR6. RESULTS Plasma level of microRNA-494-3p in sepsis patients was markedly lower than healthy controls, while plasma level of TLR6 was conversely higher in sepsis patients. With the prolongation of LPS induction in RAW264.7 cells, expression levels of TLR6 and TNF-α gradually increased, whereas microRNA-494-3p expression decreased. Transfection of microRNA-494-3p mimics in RAW264.7 cells reduced TNF-α level, and inhibited nuclear translocation of NF-κB p65. TLR6 was found to be a target gene of microRNA-494-3p, and its expression was markedly downregulated by microRNA-494-3p overexpression. Finally, we proved that the inhibitory effects of microRNA-494-3p on TNF-α level and nuclear translocation of NF-κB p65 were reversed by TLR6. CONCLUSIONS High expression of microRNA-494-3p attenuated sepsis-induced inflammatory response by degrading TLR6.

Abstract
OBJECTIVE To explore the influences of the up-regulation of micro ribonucleic acid (miR)-126 on septic inflammation and prognosis through the AKT/Rac1 signaling pathway. MATERIALS AND METHODS Human pulmonary microvascular endothelial cells (HMVECs) were cultured and transfected with miR-126 mimics. The HMVECs in the logarithmic growth phase in different groups were incubated with thrombin. The transmembrane resistivity of HMVECs was detected as the permeability via Electric Cell-substrate Impedance Sensing (ECIS) system. The endothelial cell space was observed via immunofluorescence. The mouse model of sepsis was then established and the serum was extracted to detect interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). The survival curve was plotted based on the death time. The Statistical Product and Service Solutions (SPSS) 22.0 was used for statistical analysis, and p<0.05 suggested that the difference was statistically significant. RESULTS Thrombin could significantly increase the permeability of HMVECs, while the overexpression of miR-126 markedly inhibited the increased permeability. The overexpression of miR-126 also reduced the endothelial cell space induced by thrombin. In addition, the serum IL-6 and TNF-α levels of sepsis mice in miR-126 overexpression group were significantly decreased compared to those in the control group. Moreover, the death rate of mice exogenously expressing miR-126 was lower than that in the control group. CONCLUSIONS The up-regulation of miR-126 inhibited the septic inflammation and improved the prognosis of sepsis mice through the AKT/Rac1 signaling pathway.

Abstract
BACKGROUND Endoscopic resection cap technique (ER-Cap), multiband mucosectomy (MBM), and endoscopic submucosal dissection (ESD) have been widely applied in the treatment of esophageal squamous neoplasia and cancer. However, little is known with regards to the comparison of these methods. This study aimed to compare the feasibility, safety, effectiveness, and costs of these three techniques. METHODS A retrospective analysis of patients with squamous premalignant or early malignant lesions of the esophagus undergoing ER-Cap, MBM, or ESD from January 2009 to December 2015 in one of the centers in China was performed. The procedural data and follow-up data for all patients were recorded. RESULTS A total of 672 patients with 733 lesions were included; 148 lesions (133 patients) were treated with ER-Cap, 427 lesions (388 patients) with MBM, and 158 lesions (151 patients) with ESD. The mean age was 61.59 years and the male-to-female ratio was 2.78:1. The operation time was significantly shorter for ER-Cap (29.26 ± 16.73 mins, p < 0.001) group, and the hospitalization costs were significantly lower in the MBM group (20,942.03 ± 8435.56¥, p = 0.003). The resection sample size of ESD was significantly larger (4.40 ± 1.20 cm, p < 0.001) and the en bloc resection rate of ESD was significantly higher (p < 0.001) than that of the other two groups. The frequencies of perforation, bleeding, and cicatricial stenosis were significantly lower in the MBM group (p < 0.001, p = 0.011, p = 0.009). Three local recurrences were observed in the ER-Cap group, while no recurrence was observed in MBM and ESD groups. There were three and two metastatic patients observed in the MBM and ESD groups, respectively. CONCLUSIONS ER-Cap, MBM, and ESD are all minimally invasive, safe, and effective methods for treating early esophageal squamous cell carcinoma. MBM could be considered as a good alternative when performed by a less-experienced endoscopist in high-incidence areas with limited resources.

Abstract
BACKGROUND Laterally spreading tumor (LST) is a type of precancerous lesion of colorectal cancer with high malignant potential. The present study aimed to evaluate long-term outcomes of endoscopic treatment for LST in Chinese patients. METHODS This study was a retrospective review of data collected from 653 included patients with LST from six regional representative hospitals in China between January 2007 and January 2017. Demographic characteristics, endoscopic features of LST, operation-related data, and follow-up results were collected and analyzed. RESULTS LST-granular type (LST-G, 80.3%) was much more common than LST-non-grandular type (LST-NG, 19.7%). The overall submucosal invasion rate of all LSTs was 6.1% and the submucosal invasion rate of LST-NG was significantly higher than that of LST-G (6.79% vs. 3.87%, p = 0.000). The en bloc resection rate of ESD and EMR treatment was 96% and 93.7%, respectively, with pathologic R0 resection rate of 90.1% and 82.8%. After an average duration of follow-up about 34.52 ± 11.76 months, the recurrence rate of ESD was 3.47%, and the recurrence rate of EMR was 8.8% after an average follow-up of about 38.44 ± 4.42 months. However, the recurrence rate of ESD was much lower than piecemeal EMR for LST (3.47% vs. 8.62%, p = 0.017). Retroflexion-assisted technique applied for resection of rectal LST was associated with a significantly shortened operating time (85.40 min vs. 174.18 min, p = 0.002). CONCLUSION Endoscopic resection is a safe and efficient modality for the treatment of colorectal LST with a relatively low recurrence rate and shortened operating time with the use of retroflexion.

Abstract
BACKGROUND AND AIMS Esophageal squamous cell neoplasia (ESCN) has a significant risk for progression to cancer. Current treatment options, endoscopic mucosal resection (EMR) or submucosal dissection (ESD), have their limitations. The cryoballoon focal ablation system (CbFAS) is a novel endoscopic ablation therapy device. We aimed to assess the safety, tolerability, and efficacy of CbFAS for eradication of ESCN. METHODS In this single-center prospective trial in China, patients with 1 flat unstained lesion (USL) on Lugol chromoendoscopy that contained moderate- or high-grade intraepithelial neoplasia (MGIN or HGIN, respectively) were enrolled. CbFAS was performed using side-by-side applications of 10 seconds, treatment was repeated at 3-month intervals until a complete response (CR) was established. The response at 12 months was the primary trial endpoint. Safety phone calls were performed at 2, 7, and 30 days after the initial CbFAS. RESULTS We enrolled 80 patients (59 MGIN, 21 HGIN) with a median USL length of 3 cm (interquartile range [IQR], 3-4). Seventy-nine received treatment, with a median of 5 side-by-side applications (IQR, 4-7) per patient over a median of 8 minutes (IQR, 5-10). After a single treatment, 70 of 78 patients (90%) exhibited CR, and 1 was lost to follow-up. The other 8 with persisting USLs were retreated, and all achieved CR after this second treatment. At 12 months after the initial CbFAS, 76 of 78 patients (97%) exhibited CR and 2 (3%) had recurrent MGIN. No strictures or serious adverse events occurred. Four patients developed self-limiting mucosal lacerations on balloon inflation. The postprocedure median pain score was 1 of 10 (IQR, 0-2) at day 2 and 0 (0-0) at days 7 and 30. CONCLUSIONS The results suggest that the CbFAS is safe, well tolerated, and effective in inducing endoscopic and histologic remission in patients with ESCN of limited size.

Abstract
Esophageal cancer staging is important for the treatment of esophageal cancer. Endoscopic ultrasonography (EUS) is a common diagnostic tool for esophageal cancer prior to surgery. However, EUS is unable to accurately discriminate the N-staging of lymph nodes. In order to distinguish an optimized standard for malignant lymph node diagnosis, the present study compared lymph nodes detected by EUS and surgery. A total of 112 patients were preoperatively examined with EUS and staged according to the 7th Edition of the American Joint Committee on Cancer Staging Manual. The results of EUS were compared with surgical findings. The critical values of long diameter, short diameter and lymph node number detected by EUS were >7.5, >5.5 mm and >2, respectively; indexes, including long diameter >7.5 mm, short diameter >5.5 mm, round, low echo, edge smooth, near lesion and detected lymph node number (>2) and T3/4 staging, met significance in the EUS group compared with the surgical group (P<0.05). Furthermore, the area under curve (AUC) value of the EUS (0.801) was superior to the conventional, surgical method (0.779). Although EUS improved the diagnostic accuracy of esophageal N staging, it was not able to satisfactorily distinguish between N2 and N3 staging. Advancements in EUS may enhance its detection ability, further improving the diagnostic accuracy of lymph node metastasis.

Abstract
BACKGROUND & AIMS Endoscopic ultrasound (EUS)-guided fine needles with side fenestrations are used to collect aspirates for cytology analysis and biopsy samples for histologic analysis. We conducted a large, multicenter study to compare the accuracy of diagnosis via specimens collected with fine-needle biopsy (FNB) versus fine-needle aspiration (FNA) for patients with pancreatic and nonpancreatic masses. METHODS We performed a prospective single-blind study at 5 tertiary care centers in China. The study comprised 408 patients undergoing EUS for a solid mass (>1 cm) in the pancreas, abdomen, mediastinum, or pelvic cavity, from December 2014 through January 2016. Patients were randomly assigned to groups (1:1) for assessment by FNA (n = 190) or FNB (n = 187). After lesions were identified by EUS, samples were collected in a total of 4 passes by each needle. All procedures were performed by experienced endosonographers; cytologists and pathologists were blinded to the sample collection method. Patients were followed for at least 48 weeks, and final diagnoses were obtained after surgery, imaging analysis, or resolution of lesion. The primary aim was to compare diagnostic yields of EUS-FNA with EUS-FNB for all solid masses, then separately as pancreatic and nonpancreatic masses. The secondary endpoint was the quality of histologic specimen. RESULTS Findings from FNB analysis were accurate for 91.44% of all cases, compared with 80.00% for all FNA cases, based on final patient diagnoses (P = .0015). In patients with pancreatic masses (n = 249), findings from histologic analysis of FNBs were accurate for 92.68% of the cases, compared with 81.75% for FNAs (P = .0099). In cytology analysis of pancreatic masses, samples collected by FNB accurately identified 88.62% of all pancreatic lesions, whereas samples collected by FNA accurately identified 79.37% (P = .00468). Analyses of samples of nonpancreatic masses collected by FNA versus FNB produced similar diagnostic yields. CONCLUSIONS In a prospective study of patients with pancreatic masses, we found EUS-guided FNB samples to produce more accurate diagnoses than samples collected by EUS-guided FNA samples. No difference in diagnostic yield was seen between EUS-FNA and EUS-FNB for nonpancreatic masses. Clinical Trials.gov no: NCT02327065.

Abstract
OBJECTIVE To explore the risk factors contributing to the progression-free survival rate of patients undergoing endoscopic non-curative resection. METHODS Clinicopathological data of patients with early colorectal carcinoma and intraepithelial neoplasia undergoing endoscopic resection in our department from January 2009 to January 2015 were collected. Associated factors affecting the progression-free survival rate of the early colorectal carcinoma after endoscopic non-curative resection were analyzed. Any of the following conditions was defined as endoscopic non-curative resection: (1) positive lateral or vertical cutting margin; (2) submucosa invasion depth ≥1 000 μm; (3) vascular or lymphatic invasion; (4) low differentiation, including signet ring cell carcinoma or mucinous adenocarcinoma; (5) high grade tumor budding. RESULTS Clinicopathological data of 840 cases were collected. According to China's Endoscopic Screening, Diagnosis and Treatment Guidelines for Early Colorectal Cancer, 56(56/840, 6.7%) cases were defined as the non-curative resection, the metastasis or recurrence rate was 14.3%(8/56), 3-year progression-free survival rate was 85.7%(48/56), and 3-year overall survival rate was 94.6%(53/56). Univariate prognostic analysis showed that 3-year progression-free survival rate in low and moderate-high differentiation adenocarcinoma was 25.0% and 90.4%(χ2=6.711, P=0.010), in patients with submucosa invasion depth ≥2 000 μm and <2 000 μm was 75.0% and 93.8%(χ2=6.745, P=0.009), and in patients with and without vascular or lymphatic invasion was 60.0% and 88.2%(χ2=7.708, P=0.005), whose differences were all significant. Multivariate Cox regression analysis revealed that low differentiation adencarcinoma (P=0.015, HR=8.021, 95%CI: 1.499-42.921), invasion depth ≥2 000 μm (HR=6.823, 95%CI: 1.299-35.848) and vascular or lymphatic invasion (HR=18.143, 95%CI: 2.079-158.358) were independent risk factors for the progression-free survival rate of the early colorectal carcinoma after endoscopic non-curative resection. CONCLUSION Pathology after endoscopic non-curative resection for early colorectal carcinoma indicates that low differentiation adenocarcinoma, submucosa invasion depth ≥2 000 μm and vascular or lymphatic invasion are independent risk factors of poor prognosis.

Abstract
OBJECTIVE To investigate the security and efficacy of a new endoscopic closure method of large defects after endoscopic full-thickness resection (EFTR) double purse-string suture using two endoloops and metallic clips via single-channel endoscopy. METHODS Clinical data of 23 cases with submucosal tumors (SMT) who received endoscopic resection from June 2015 to July 2016 in our National Cancer Center were collected. For gastric and esophageal SMTs or the mucosa layer injured during submucosal tunneling endoscopic resection (STER), double purse-string suture was conducted after EFTR. The key steps of closure were as follows: the endoloop was installed onto the delivery system and inserted into the gastric cavity to the defect location with endoscopy and then opened; the clips were transported into the gastric cavity from the biopsy channel; the endoloop was fixed onto the full thickness of gastric wall along the edge of the defect by clips one by one between the interval of about 5 mm; the endoloop was tightened slowly till the entire circumference of the defect was sutured, thus, one purse-string suture was done; in accordance with the operation above, another endoloop was released, and the second endoloop was fixed at 5-10 mm to the outer edge of the original one, and tied the endoloop gently; this sequence was continued till there was no gap, thus, the double-purse string suture was finished. A total of 23 patients were enrolled in the study, including 18 with gastric tumor and 5 with esophageal tumor, 15 males and 8 females, with the average age of 56 (19 to 76) years. RESULTS Eighteen cases of gastric SMT were successfully treated by endoscopic EFTR and double purse-string suture. The esophageal mucosa layer of all the 5 cases of esophageal SMT, including tumors of 3 cases located in cervical esophagus at 15-20 cm from the fore-tooth, 1 esophageal leiomyoma case complicated with squamous cell carcinoma in situ, and 1 case of mucosal layer injury during submucosal tunneling endoscopic resection (STER), was successfully repaired by using double purse-string suture. The mean maximum diameter of tumor was 2.3 cm, and the average suture time was 22.8 min. Postoperative pathology showed that 13 cases were gastrointestinal stromal tumors (GIST), 7 cases were leiomyoma, 2 cases were neurilemmoma, and 1 case was leiomyoma complicated with early squamous cell carcinoma in situ. No severe complications occurred during or after the operation. CONCLUSIONS The double purse-string suture by using metallic clips and endoloops with single channel endoscope is a relatively safe, easy, and reliable technique for repairing large gastric defect after EFTR. For cervical esophageal SMT, or the SMT combined with superficial mucosal lesions, and for the mucosa layer injury during submucosal tunneling endoscopic resection(STER), double purse-string suture is helpful to perform the closure.

Abstract
BACKGROUND AND AIMS Accurate prediction of the response to preoperative chemoradiotherapy (CRT) potentially assists in the individualized selection of treatment. Endorectal US (ERUS) is widely used for the pretreatment staging of rectal cancer, but its use for preoperatively predicting the effects of CRT is not well evaluated because of the inflammation, necrosis, and fibrosis induced by CRT. This study assessed the value of sequential ERUS in predicting the efficacy of preoperative CRT for locally advanced rectal cancer. METHODS Forty-one patients with clinical stage II/III rectal adenocarcinoma were enrolled prospectively. Radiotherapy was delivered to the pelvis with concurrent chemotherapy of capecitabine and oxaliplatin. Total mesorectal excision was performed 6 to 8 weeks later. EUS measurements of primary tumor maximum diameter were performed before (ERUS1), during (ERUS2), and 6 to 8 weeks after (ERUS3) CRT, and the ratios of these were calculated. Correlations between ERUS values, tumor regression grade (TRG), T down-staging rate, and pathologic complete response (pCR) rate were assessed, and survival was analyzed. RESULTS There was no significant correlation between ERUS2/ERUS1 and TRG. The value of ERUS3/ERUS1 correlated with pCR rate and TRG but not T down-staging rate. An ERUS3 value of 6.3 mm and ERUS3/ERUS1 of 52% were used as the cut-off for predicting pCR, and patients were divided into good and poor prognosis groups. Although not statistically significant, 3-year recurrence and survival rates of the good prognosis group were better than those of the poor prognosis group. CONCLUSIONS Sequential ERUS may predict therapeutic efficacy of preoperative CRT for locally advanced rectal cancer. (Clinical trial registration number: NCT01582750.).

Abstract
The role of estrogen in inducing chemoresistance is not yet fully understood. The objective of this study was to observe the relationship between estrogen levels and cellular response to chemotherapeutic drugs in non-small cell lung cancer (NSCLC) and to reveal the potential mechanisms involved. Cell viability was analyzed after pre-treating NSCLC cells with different levels of estrogen (E2), followed by treatment with an anti-tumor drug for 48 h. The roles of various estrogen receptors (ERs) were examined in vitro by blocking the activity of each ER individually. The ER pathway was further confirmed in NSCLC tissues. It was found that 10-1000 nM E2 resulted in a decreased cellular response to DDP in H1650 cells compared to the use of cisplatin alone (P < 0.05). However, this result was not demonstrated in H1299 cells, which lack p53. Both ERa and ERb were associated with E2-induced cisplatin chemoresistance, though they had opposite functions. p53 expression did not correlate with the expression of ERa or ERb individually. However, a statistically significant correlation between p53 expression and ERa to ERb mRNA ratio was observed (P < 0.001, R = -0.676). These findings suggest that E2-induced DDP chemoresistance depends on the balance between ERa and ERb expression and the p53 pathway.

Abstract
OBJECTIVE To analyze the factors affecting lymph node metastasis and the prognosis of rectal neuroendocrine tumors after surgical treatment. METHODS A retrospective analysis was conducted using the clinical data from 156 cases of rectal neuroendocrine tumors during the period of January 1999 to December 2013. The Kaplan-Meier method was used to calculate the survival time, Cox regression analysis was performed for statistical analysis of clinicopathological factors that may be associated with lymph node metastasis and prognosis, and correlation analysis was carried out using binary logistic regression. RESULTS The overall 5-year survival rate of the entire group was 95.7%. Multivariate analysis showed that the depth of invasion was an independent prognostic factor (P < 0.001). The incidence of lymph node metastasis was 7.7% (12/156), and logistic regression analysis showed that lymph node metastasis was related to the depth of invasion (P = 0.003) and tumor diameter (P = 0.006). CONCLUSION The surgical approach of rectal neuroendocrine tumors should be selected based on a comprehensive consideration of factors such as tumor size, depth of invasion and lymph node metastasis.

Abstract
OBJECTIVE To examine the characteristics of esophageal squamous cancers with multiple primary cancers in another organ. METHODS Between January 2012 and December 2014, 3 104 patients with esophageal squamous cell carcinoma treated in Cancer Institute and Hospital, Chinese Academy of Medical Sciences, were reviewed for the presence of an additional primary cancer retrospectively. The patients were divided into two groups according to whether they had multiple primary cancer. RESULTS Totally 369 (11.9%) patients were found multiple primary cancer in the other organs. Among these patients, 72.4% was found synchronously, another primary cancer was found in the head and neck region in 211 (6.8%), in the stomach in 140 (4.2%), and in the lung, colon, breast, and other locations in the remaining patients. Of the 211 patients with another primary cancer in the head and neck region, 156 (73.2%) had hypopharyngeal cancer. Furthermore, the incidence of intraesophageal multiple cancerous lesion in the patients with primary cancer in the head and neck region was significantly higher than that in those whose other primary cancers were gastric cancer or in those with non-multiple primary cancer (P<0.01). CONCLUSION There is a high incidence of multiple primary cancers in patients with esophageal squamous carcinoma, mostly found synchronously. The leading multiple primary cancers were head and neck cancer and stomach cancer. Intraesophageal multiple cancerous lesion is an indicator for a second primary cancer in head and neck. A better knowledge of the relationships between esophageal carcinoma and cancers in other organs may lead to earlier detection of other primary cancers and improved therapeutic results.

Abstract
OBJECTIVE To evaluate the efficacy of radiofrequency ablation(RFA) combined with endoscopic resection(ER) for eradicating widespread early non-flat type esophageal squamous cell carcinoma (ESCC) and precancerous lesions. METHODS Retrospective analysis was performed on the clinical data of 4 patients with early non-flat type ESCC and precancerous lesions in January 2010 at the Cancer Institute and Hospital, Chinese Academy of Medical Sciences. Proportion of patients with histological complete response (CR) 3 months, 12 months to 5 years after operation and adverse events were observed. RESULTS These 4 patients were all male, aged from 47 to 71 (mean age 62) years, including 2 of ESCC, 1 of HGIN, 1 of MGIN confirmed by pathology. USL length was 6-12 (mean 8.5) cm. Treatment area (TA) length was 8-14 (mean 10.5) cm. Three cases were 0-II a (mean length 2 cm), and 1 case 0-II c (mean length 4 cm). Lesions of 2 cases were complete cycle, and other 2 cases occupied 3/4 circumference. Four patients completed their operations successfully. Total operation time was 42-105 (mean 66.8) min, RFA time was 3-12 (mean 8.25) min, and ER time was 6-20 (10.25) min, without bleeding and perforation. The mean hospital stay was 3 days. Pathology examination showed that 2 cases were ESCC G2 (lesion length 12, 8 cm; non-flat type lesion length 3, 4 cm), 1 was HGIN (lesion length 12 cm; non-flat type lesion length 1 cm) and 1 was MGIN (lesion length 6 cm; non-flat type lesion length 2 cm). Three cases were CR 3 months, 1 to 5 years after operation. One case had HGIN at 3-month and MGIN at 1-year and 3-year during follow up, and was CR after treatment with HALO. Postoperative esophageal stenosis occurred in 4 cases. Among them, 2 cases were mild without treatment, and 2 were severe, who were relieved by endoscopic water sac dilation for 5-8 (mean 6.5) times. CONCLUSION RFA combined with ER is effective and safe in the treatment of patients with early non-flat esophageal squamous cell carcinoma and precancerous lesions.
