Purpose of the guidelines The primary objective these guidelines is to provide general clinicians with information that would guide them make informed choices available diagnosis/treatment strategies for esophageal cancer (intended malignant tumors epithelial origin, not any other non-epithelial esophagus or metastatic tumors). Furthermore, are also intended as an aid healthcare professionals than physicians, patients, and patients’ family members, obtain understanding fundamental...
treatment, thereby reducing the difference in treatment results among different institutions; (3) to reduce unnecessary costs and efforts; (4) help enable people undergo without anxiety.These guidelines provide only guidance on indications for do not restrict or prohibit use of any deviating from those described herein. ResponsibilitiesThe Japan Esophageal Society assumes responsibility content these guidelines.However, should be borne by doctor providing shall rest with Society.Basic...
Endoscopic resection (ER) includes endoscopic mucosal (EMR), wherein the affected lesion is held or aspirated and resected with a snare, submucosal dissection (ESD), which refers to en bloc of an extensive using IT knife hook [1][2][3][4].Other treatments available include photodynamic therapy (PDT), argon plasma coagulation (APC), electromagnetic therapy.
The Japan Gastroenterological Endoscopy Society has developed endoscopic submucosal dissection/endoscopic mucosal resection guidelines. These guidelines present recommendations in response to 18 clinical questions concerning the preoperative diagnosis, indications, methods, curability assessment, and surveillance of patients undergoing for esophageal cancers based on a systematic review scientific literature.
Predicting invasion depth of superficial esophageal squamous cell carcinoma is crucial in determining the precise indication for endoscopic resection because rate lymph node metastasis increases proportion to carcinoma. Previous studies have shown a close relationship between microvascular patterns observed by Narrow Band Imaging magnifying endoscopy and Thus, Japan Esophageal Society (JES) developed simplified classification estimating carcinomas. We conducted prospective study evaluate...
Although radical surgery is recommended for patients not meeting the curative criteria endoscopic submucosal dissection (ESD) of early gastric cancer (EGC) because potential risk lymph node metastasis (LNM), this recommendation may be overestimated and excessive. We aimed to establish a simple scoring system decision making after ESD.This multicenter retrospective study consisted two stages. First, risk-scoring LNM was developed using multivariate logistic regression analysis in 1,101 who...
9 %, middle thoracic: 48.0 lower 27.7 % and EG junction: 6.6 %.Superficial carcinomas (Tis, T1a, T1b) were 36.7 %.As for the histologic type of biopsy specimens, squamous cell carcinoma adenocarcinoma accounted 90.5 3.8 respectively.Regarding clinical results, 5-year survival rates patients treated using endoscopic mucosal resection, concurrent chemoradiotherapy, radiotherapy alone, chemotherapy or esophagectomy 86.2, 27.9, 20.2, 5.8, 55.9 respectively.Esophagectomy was performed in 3844...
After publication of the guidelines, Committee on Guidelines for Diagnosis and Treatment Esophageal Cancer Japan Society has taken initiative to continue review contents guidelines conduct public relations dissemination/utilization activities.A revision is planned approximately 5 years after this guideline.In addition, a prompt report will be made when results clinical study(ies) are published or in accordance with changes medical circumstances, such as health insurance coverage.
Background & AimsEsophagectomy is the standard treatment for stage I esophageal squamous cell carcinoma (ESCC). We conducted a single-arm prospective study to confirm efficacy and safety of selective chemoradiotherapy (CRT) based on findings from endoscopic resection (ER).MethodsWe performed patients with T1b (SM1–2) N0M0 thoracic ESCC December 2006 through July 2012; 176 underwent ER. Based ER, received following: no additional pT1a tumors negative margin lymphovascular invasion (group A);...
Abstract This is the second half of English edition Japanese Classification Esophageal Cancer, 12th Edition that was published by Japan Society in 2022.
Poor counter traction and poor field of vision make endoscopic submucosal dissection (ESD) difficult. Good allows dissections to be performed more quickly safely. Position change, which utilizes gravity, is the simplest method create a clear vision. It useful especially for esophageal colon ESD. The second easiest clip with line method. Counter made by accomplishes creation suitable thereby making ESD efficient safe. author published this in 2002. name was not established those days; cutting...
Background and Aim: No studies have previously described the learning curve for colonic endoscopic submucosal dissection (ESD). The aim of present study was to describe ESD large colorectal tumors based on a single colonoscopist's experience. Methods: carried out 120 in 115 patients (68 males, median age 70 years). All procedures were by experienced colonoscopist. cases grouped chronologically into three periods: (1st): 1–40; (2nd): 41–80; (3rd): 81–120. Results: changes proficiency over...
The extent of node dissection in esophageal cancer surgery is usually estimated by the number resected nodes, irrespective area dissection. efficacy lymph was evaluated according to location primary tumor. study group comprised 3827 patients who underwent R0 esophagectomy with three-field for squamous cell carcinoma, registered a nationwide registry Japan. areas were classified into zones AJCC Staging Manual. Efficacy Index (EI) calculating frequency and patient survival metastases each zone...
Objectives A Japanese multicenter prospective cohort study examining endoscopic resection ( ER ) for early gastric cancer EGC has been conducted using a Web registry developed to determine the short‐term and long‐term outcomes based on absolute expanded indications. We hereby present of this study. Methods All consecutive patients with or suspected undergoing at 41 participating institutions between July 2010 June 2012 were enrolled prospectively registered into registry. The baseline...
We deeply appreciate the great contributions of many physicians in registry esophageal cancer cases.The Comprehensive Registry Esophageal Cancer Japan, 2012, was published here, despite some delay.The complies with Act for Protection Personal Information.The encryption a HASH function is used anonymity an unlinkable fashion.We briefly summarized 2012.Japanese Classification 10th [1] and UICC TNM 7th [2] were staging according to subjected year.A total 8003 cases registered from 316...
Abstract Background Esophageal cancer is the eighth most common cause of mortality in Japan. More than 11,000 people had died from esophageal 2018. The Japan Society has collected data on patients' characteristics, performed treatment, and outcomes annually. Methods We analyzed patients who first visited participating hospitals 2013. In 2019, collection method was changed an electronic submission to a web-based using National Clinical Database (NCD). Japanese Classification Cancer 10th by...
