Abstract
In this editorial, we comment on the article by Wang et al published in the recent issue of the World Journal of Gastroenterology in 2023. We focused on identifying risk factors for lymph node metastasis (LNM) in superficial esophageal squamous cell carcinoma (SESCC) patients and how to construct a simple and reliable clinical prediction model to assess the risk of LNM in SESCC patients, thereby helping to guide the selection of an appropriate treatment plan. The current standard treatment for SESCC is radical esophagectomy with lymph node dissection. However, esophagectomy is associated with considerable morbidity and mortality. Endoscopic resection (ER) offers a safer and less invasive alternative to surgical resection and can enable the patient's quality of life to be maintained while providing a satisfactory outcome. However, since ER is a localized treatment that does not allow for lymph node dissection, the risk of LNM in SESCC limits the effectiveness of ER. Understanding LNM status can aid in determining whether patients with SESCC can be cured by ER without the need for additional esophagectomy. Previous studies have shown that tumor size, macroscopic type of tumor, degree of differentiation, depth of tumor invasion, and lymphovascular invasion are factors associated with LNM in patients with SESCC. In addition, tumor budding is commonly associated with LNM, recurrence, and distant metastasis, but this topic has been less covered in previous studies. By comprehensively evaluating the above risk factors for LNM, useful evidence can be obtained for doctors to select appropriate treatments for SESCC patients.

Abstract
BACKGROUND AND AIMS Endoscopic resection (ER) is a minimally invasive treatment for superficial esophageal squamous cell carcinoma (SESCC). Post-ER scars complicate en bloc resection, even with advanced techniques, such as endoscopic submucosal dissection. The cryoballoon ablation system (CBAS) effectively manages Barrett's esophagus but has limited evidence in SESCC treatment, particularly on post-ER scars. This study aimed to evaluate the efficacy and safety of the CBAS for treating SESCC on post-ER scars. METHODS This prospective study was conducted at two tertiary referral centers in Japan in patients endoscopically diagnosed with T1a SESCC on the post-ER scar. Focal CBAS was used for cryoablation, with specific criteria for lesion selection and treatment method. The primary endpoint was local complete response (L-CR) rate of the primary lesion 48 weeks after the first cryoablation as evaluated by an independent central evaluation committee. RESULTS From October 2020 to October 2021, 15 patients with 17 lesions underwent cryoablation, with two requiring repeat cryoablation. The L-CR rate for primary and all lesions evaluated by the central evaluation committee was 100%. The endoscopist's evaluation was consistent with these results. The median procedure time was 9 min. Eight patients experienced no pain, and the highest pain score reported on a numeric 1-10 rating scale was 3. The technical success rate was 94.7% (18/19). Throughout the median follow-up period of 14.3 months, recurrences, deaths, or severe treatment-related adverse events were not reported. CONCLUSIONS CBAS is a potentially safe and effective approach for SESCC on post-ER scars and represents an encouraging alternative to traditional endoscopic treatments.

Abstract
BACKGROUND Superficial esophageal squamous cell carcinoma (ESCC) is defined as cancer infiltrating the mucosa and submucosa, regardless of regional lymph node metastasis (LNM). Endoscopic resection of superficial ESCC is suitable for lesions that have no or low risk of LNM. Patients with a high risk of LNM always need further treatment after endoscopic resection. Therefore, accurately assessing the risk of LNM is critical for additional treatment options. AIM To analyze risk factors for LNM and develop a nomogram to predict LNM risk in superficial ESCC patients. METHODS Clinical and pathological data of superficial ESCC patients undergoing esophagectomy from January 1, 2009 to January 31, 2016 were collected. Logistic regression analysis was used to predict LNM risk factors, and a nomogram was developed based on risk factors derived from multivariate logistic regression analysis. The receiver operating characteristic (ROC) curve was used to obtain the accuracy of the nomogram model. RESULTS A total of 4660 patients with esophageal cancer underwent esophagectomy. Of these, 474 superficial ESCC patients were enrolled in the final analysis, with 322 patients in the training set and 142 patients in the validation set. The prevalence of LNM was 3.29% (5/152) for intramucosal cancer and increased to 26.40% (85/322) for submucosal cancer. Multivariate logistic analysis showed that tumor size, invasive depth, tumor differentiation, infiltrative growth pattern, tumor budding, and lymphovascular invasion were significantly correlated with LNM. A nomogram using these six variables showed good discrimination with an area under the ROC curve of 0.789 (95%CI: 0.737-0.841) in the training set and 0.827 (95%CI: 0.755-0.899) in the validation set. CONCLUSION We developed a useful nomogram model to predict LNM risk for superficial ESCC patients which will facilitate additional decision-making in treating patients who undergo endoscopic resection.

Abstract
BACKGROUND The treatment of superficial esophageal squamous cell carcinoma (SESCC) is mainly based on endoscopic and surgical procedures. For some patients, surgical treatment alone is associated with a poor prognosis. How to screen out patients with poor prognosis and give appropriate intervention is a challenge for clinicians. Therefore, it is very important to find more convenient and effective prognostic indicators for the survival of patients to guide further treatment.
AIM To evaluate the prognostic value of peripheral blood systemic inflammatory response index (SIRI) and prognostic nutritional index (PNI) in patients with SESCC.
METHODS The clinical, biochemical, and pathological data of 122 patients with SESCC were retrospectively analyzed. The optimal cut-off values of SIRI and PNI were determined using the receiver operating characteristic (ROC) curve. According to the optimal cut-off values of SIRI and PNI, the patients were divided into a low SIRI group and a high SIRI group, and a low PNI group and a high PNI group. The Kaplan-Meier (K-M) method was used for survival analysis, and the Log-rank method was used to evaluate the difference between groups. COX univariate and multivariate regression analyses were performed to determine the predictive factors for the prognosis of patients with SESCC.
RESULTS The overall survival time of patients in the low SIRI group was significantly longer than that of patients in the high SIRI group (P = 0.001). The overall survival time of patients in the high PNI group was significantly longer than that of patients in the low PNI group (P = 0.014). Preoperative SIRI and PNI were identified to be independent risk factors for the overall survival of patients with SESCC.
CONCLUSION Preoperative SIRI and PNI are simple and reliable biomarkers for predicting the prognosis of patients with SESCC.

Abstract
BACKGROUND Endoscopic ultrasonography (EUS) and magnifying endoscopy (ME) reliably determine indications for endoscopic resection in patients with superficial esophageal squamous cell carcinoma (SESCC). ME is widely accepted for predicting the invasion depth of superficial esophageal cancer with satisfying accuracy. However, the addition of EUS is controversial.
AIM To evaluate the diagnostic efficiency of ME vs EUS for invasion depth prediction and investigate the influencing factors in patients with SESCC to determine the best diagnostic model in China.
METHODS We retrospectively analyzed patients with suspected SESCC who completed both ME and EUS and then underwent endoscopic or surgical resection at Sun Yat-Sen University Cancer Center between January 2018 and December 2021. We evaluated and compared the diagnostic efficiency of EUS and ME according to histological results, and investigated the influencing factors.
RESULTS We included 152 lesions from 144 patients in this study. The diagnostic accuracies of ME and EUS in differentiating invasion depth were not significantly different (73.0% and 66.4%, P = 0.24); both demonstrated moderate consistency with the pathological results (ME: kappa = 0.58, 95% confidence interval [CI]: 0.48-0.68, P < 0.01; EUS: kappa = 0.46, 95%CI: 0.34-0.57, P < 0.01). ME was significantly more accurate in the diagnosis of high-grade intraepithelial (HGIN) or carcinoma in situ (odds ratio [OR] = 3.62, 95%CI: 1.43-9.16, P = 0.007) subgroups. Using a miniature probe rather than conventional EUS can improve the accuracy of lesion depth determination (82.3% vs 49.3%, P < 0.01). Less than a quarter of circumferential occupation and application of a miniature probe were independent risk factors for the accuracy of tumor invasion depth as assessed by EUS (< 1/4 circumferential occupation: OR = 3.07, 95%CI: 1.04-9.10; application of a miniature probe: OR = 5.28, 95%CI: 2.41-11.59, P < 0.01). Of the 41 lesions (41/152, 27.0%) that were misdiagnosed by ME, 24 were corrected by EUS (24/41, 58.5%).
CONCLUSION Preoperative diagnosis of SESCC should be conducted endoscopically using white light and magnification. In China, EUS can be added after obtaining patient consent. Use of a high-frequency miniature probe or miniature probe combined with conventional EUS is preferable.

Abstract
BACKGROUND Treatment strategies for superficial esophageal squamous cell carcinoma (SESCC) are determined mainly on the basis of the invasion depth. The Japan Esophageal Society (JES) developed a simplified magnifying endoscopic classification for estimating the invasion depth of SESCC. We aimed to evaluate its accuracy. METHODS We prospectively applied the JES classification for estimating the invasion depth of SESCC to 204 consecutive lesions from 6 hospitals in Japan between April 2016 and October 2018. We analyzed the accuracy of the endoscopic diagnosis by adding the following two categories to the JES classification: ≥ 7 mm lesion in B2 vessels (defined as B2 ≥ 7 mm) and B2 vessels with inflammation (defined as B2i). RESULTS After applying the exclusion criteria, 201 lesions remained in the analysis. The diagnostic value of type B1, B2, B3 vessels were as follows: sensitivity, 93.9%, 68.0%, 25.0%; specificity, 81.1%, 89.2%, 99.4%; positive predictive value (PPV), 95.6%, 47.2%, 75.0%; negative predictive value (NPV), 75.0%, 95.1%, 95.4%; and accuracy, 91.5%, 86.5%, 95.0%, respectively. A retrospective analysis showed that the diagnostic accuracy was higher in type B2 vessels (86.5% to 92.0%). An avascular area (AVA) was found in 55 (27%) of the 201 lesions, which tended to be associated with a deeper pathological diagnosis of each Type B vessel. In an additional analysis, B2 ≥ 7 mm and B2i improved the diagnostic accuracy of type B2 vessels from 86.5% to 92.0%. CONCLUSIONS The JES classification is useful for estimating the invasion depth of SESCC. The diagnostic accuracy for type B2 vessels was low, which may be improved by using B2 ≥ 7 mm and B2i.

Abstract
Although surgery was the standard treatment for early gastrointestinal cancers, endoscopic resection is now a standard treatment for early gastrointestinal cancers without regional lymph node metastasis. High-definition white light endoscopy, chromoendoscopy, and image-enhanced endoscopy such as narrow band imaging are performed to assess the edge and depth of early gastrointestinal cancers for delineation of resection boundaries and prediction of the possibility of lymph node metastasis before the decision of endoscopic resection. Endoscopic mucosal resection and/or endoscopic submucosal dissection can be performed to remove early gastrointestinal cancers completely by en bloc fashion. Histopathological evaluation should be carefully made to investigate the presence of risk factors for lymph node metastasis such as depth of cancer invasion and lymphovascular invasion. Additional treatment such as radical surgery with regional lymphadenectomy should be considered if the endoscopically resected specimen shows risk factors for lymph node metastasis. This is the first Korean clinical practice guideline for endoscopic resection of early gastrointestinal cancer. This guideline was developed by using mainly de novo methods and encompasses endoscopic management of superficial esophageal squamous cell carcinoma, early gastric cancer, and early colorectal cancer. This guideline will be revised as new data on early gastrointestinal cancer are collected.

Abstract
Background The current virtual chromoendoscopy equipment cannot completely detect superficial squamous cell carcinoma (SCC) in the esophagus, despite its development in the recent years. Thus, in this study, we aimed to elucidate the appropriate air volume during endoscopic observation to improve the visibility of esophageal SCC. Methods This retrospective study included a total of 101 flat type esophageal SCCs identified between April 2017 and January 2019 at the Department of Gastrointestinal Oncology, Osaka International Cancer Institute. Video images of narrow band imaging (NBI) under both less-air and standard-air conditions were recorded digitally. Videos were evaluated by five endoscopists. Relative visibility between less-air and standard-air conditions of the brownish area, brownish color change of the epithelium, and dilated intrapapillary capillary loop (IPCL) were graded as 5 (definitely better under less-air condition) to 1 (definitely worse under less-air condition), with 3 indicating average visibility (equivalent to standard-air observation). Results The mean (standard deviation) visibility score of the brownish area, brownish color change of the epithelium, and dilated IPCLs under less-air condition were 3.94 (0.58), 3.73 (0.57), and 4.13 (0.60), respectively, which were significantly better than that under standard-air condition (p < 0.0001). Esophageal SCC evaluated as ≥ 4 in the mean visibility score of the brownish area, brownish color change of the epithelium, and dilated IPCLs accounted for 50% (51/101 lesions), 34% (34/101 lesions), and 67% (68/101 lesions), respectively. Conclusions The present results suggested that NBI with less air might improve the visibility of flat type esophageal SCC compared with NBI with standard air. Less-air NBI observation may facilitate the detection of flat type esophageal SCC. Trial registration The present study is a non-intervention trial.

Abstract
Although surgery was the standard treatment for early gastrointestinal cancers, endoscopic resection is now a standard treatment for early gastrointestinal cancers without regional lymph node metastasis. High-definition white light endoscopy, chromoendoscopy, and image-enhanced endoscopy such as narrow band imaging are performed to assess the edge and depth of early gastrointestinal cancers for delineation of resection boundaries and prediction of the possibility of lymph node metastasis before the decision of endoscopic resection. Endoscopic mucosal resection and/or endoscopic submucosal dissection can be performed to remove early gastrointestinal cancers completely by en bloc fashion. Histopathological evaluation should be carefully made to investigate the presence of risk factors for lymph node metastasis such as depth of cancer invasion and lymphovascular invasion. Additional treatment such as radical surgery with regional lymphadenectomy should be considered if the endoscopically resected specimen shows risk factors for lymph node metastasis. This is the first Korean clinical practice guideline for endoscopic resection of early gastrointestinal cancer. This guideline was developed by using mainly de novo methods and encompasses endoscopic management of superficial esophageal squamous cell carcinoma, early gastric cancer, and early colorectal cancer. This guideline will be revised as new data on early gastrointestinal cancer are collected.

Abstract
BACKGROUND AND STUDY AIMS Though intrapapillary capillary loops (IPCL) can be used to diagnose the staging of superficial esophageal squamous cell carcinoma (SESCC), the accuracy still remains controversial. Moreover, which IPCL classification is more suitable for clinical application is unclear. The aim was to evaluate the diagnostic performance of different IPCL classifications and to explore a new classification. PATIENTS AND METHODS A meta-analysis was conducted to compare the diagnostic efficiency of the three IPCL classifications for SESCC staging. STATA 12.0 software was used and bivariate mixed effects-model was applied for the meta-analysis. A new classification was developed based on the meta-analysis result. Then a single-center study was conducted for further validation analysis. RESULTS Of the 2310 citations, 14 studies fulfilled our criteria. For epithelium (EP) and lamina propria mucosa (LPM) staging tumors, IPCL showed high diagnostic accuracy (Inoue: 87.17%, Arima: 98.71%, JES: 86.70%). For muscularis mucosa (MM) and submucosa (SM1), 23.12% were underestimated and the Japan Esophageal Society classification (JES) was better than Inoue (Accuracy: 75.48% VS 58.67%, P < 0.05). For ≥ SM2, 38.86% were underdiagnosed and the diagnostic accuracy of Arima classification was significantly higher than the other two (P < 0.05). Our study showed that the new criteria had higher diagnostic sensitivity than the widely used classification (JES) for differentiating ≥ SM2 staging cancer from EP-SM1 (0.77 VS 0.50, P < 0.05). CONCLUSIONS IPCL was valuable for diagnosing SESCC staging. However, ≥ MM would be underestimated easily. Our study revealed that the diagnostic sensitivity for ≥ SM2 staging tumors was significantly improved by the new standard.

Abstract
AIM To evaluate the clinical outcomes of patients who underwent endoscopic submucosal tunnel dissection (ESTD) for esophageal squamous cell carcinoma (ESCC) and precancerous lesions.
METHODS ESTD was performed in 289 patients. The clinical outcomes of the patients and pathological features of the lesions were retrospectively reviewed.
RESULTS A total of 311 lesions were included in the analysis. The en bloc rate, complete resection rate, and curative resection rate were 99.04%, 81.28%, and 78.46%, respectively. The ESTD procedure time was 102.4 ± 35.1 min, the mean hospitalization time was 10.3 ± 2.8 d, and the average expenditure was 3766.5 ± 846.5 dollars. The intraoperative bleeding rate was 6.43%, the postoperative bleeding rate was 1.61%, the perforation rate was 1.93%, and the postoperative infection rate was 9.65%. Esophageal stricture and positive margin were severe adverse events, with an incidence rate of 14.79% and 15.76%, respectively. No tumor recurrence occurred during the follow-up period.
CONCLUSION ESTD for ESCC and precancerous lesions is feasible and relatively safe, but for large mucosal lesions, the rate of esophageal stricture and positive margin is high.

Abstract
BACKGROUND Standard endoscopic appearance is essential for the diagnosis and treatment of superficial esophageal squamous carcinoma (SESC). The aim of this study was to investigate the association between the endoscopic gross appearance and the clinicopathologic characteristics of SESC. METHODS We retrospectively analyzed the clinicopathologic characteristics of SESC according to gross endoscopic appearance in 275 patients with SESC that underwent esophagectomy or endoscopic resection (ER). RESULTS The proportion of type I or type III gross appearance, and that of types IIa, IIb, or IIc, were 26.2 and 73.8%, respectively. Type I or type III gross appearance was significantly associated with the female sex, submucosal invasion, lymphovascular invasion (LVI), and lymph node metastasis (LNM). In addition, younger age, larger tumor size, higher proportion of circumferential extension, type I or type III endoscopic gross appearance, submucosal invasion, moderate or poorly differentiated carcinoma, and LVI were significantly associated with LNM. Multivariate logistic regression analysis determined that independent predictors of LNM in patients with SESC included endoscopic gross appearance, submucosal invasion, and presence of LVI. Additionally, type I or type III endoscopic gross appearance lesions were more likely to have submucosal invasion than types IIa, IIb, or IIc. Risk factors for submucosal invasion included a gross appearance of type I or type III, moderately or poorly differentiated tumors, and presence of LVI. CONCLUSIONS We found that SESC clinical features are correlated with the endoscopic appearance. Therefore, we suggest that the endoscopic gross appearance may be a candidate for additive criteria in the indications for ER.

Abstract
BACKGROUND/AIMS The aim of this study was to analyze and propose a treatment strategy after endoscopic resection of superficial esophageal squamous cell carcinoma in a single institution. METHODS This is a retrospective review of 37 patients who were treated by endoscopic resection during a 6-year period. RESULTS The mean tumor size was 11.5±5.5 mm (range, 3 to 31 mm). Thirty-one lesions (83.8%) were treated by endoscopic submucosal dissection, and six lesions were treated by endoscopic mucosal resection (16.2%). The en bloc resection rate and complete resection rate were 91.9% and 81.8%, respectively. The tumor invasion depth was diagnosed as epithelial in five cases (13.5%), lamina propria mucosa in 12 cases (32.4%), muscularis mucosa in 10 cases (27.0%) and submucosa in 10 cases (27.0%). The complication rate was 13.5% and included three cases (8.1%) of perforation. Ten patients who had muscularis mucosa and submucosa lesions received additional treatments, including six patients who were treated with esophagectomy, three patients who were treated with radiotherapy and one patient who was treated with chemoradiotherapy. One patient with lamina propria lesions received radiotherapy due to a positive resection margin. The median follow-up duration was 22 months (range, 4 to 79 months), and no recurrence or metastasis was noted during follow-up. CONCLUSIONS Tailored management after endoscopic treatment of superficial esophageal squamous cell carcinoma can offer an acceptable oncologic outcome in early esophageal carcinoma.
