Abstract
Purpose: Completion total gastrectomy is considered an additional treatment after non-curative endoscopic resection for remnant gastric cancer. However, its high invasiveness remains a concern. This study aimed to assess the necessity of additional surgery after non-curative endoscopic submucosal dissection in patients with remnant gastric cancer.
Methods: This study included patients who underwent non-curative endoscopic submucosal dissection for remnant gastric cancer between September 2002 and January 2018. The eCura system was used to stratify the risk of lymph node metastasis into low, intermediate, or high. The overall survival, disease-specific survival, and long-term clinical course were analyzed.
Results: Among the 46 patients analyzed, 15 underwent additional completion total gastrectomy, whereas 31 were only followed up. Within a median follow-up period of 62.5 months, the additional surgery and follow-up groups showed 5-year overall survival rates of 79.4% and 76.8% (P = 0.93) and disease-specific survival rates of 92.9% and 92.7% (P = 0.98). A total of 19 low-, 8 intermediate-, and 4 high-risk patients in the follow-up group achieved 5-year disease-specific survival rates of 100%, 100%, and 33.3%. Significant differences were observed in the disease-specific survival between the low- and high-risk patients (P < 0.001) and between the intermediate- and high-risk patients (P = 0.02).
Conclusion: Risk stratification using the eCura system allows for individualized treatment decisions, with follow-up being a viable option for low- and intermediate-risk patients and additional surgery recommended for high-risk patients after non-curative endoscopic submucosal dissection for remnant gastric cancer.
期刊介绍：
The Journal of Gastrointestinal Cancer is a multidisciplinary medium for the publication of novel research pertaining to cancers arising from the gastrointestinal tract.The journal is dedicated to the most rapid publication possible.The journal publishes papers in all relevant fields, emphasizing those studies that are helpful in understanding and treating cancers affecting the esophagus, stomach, liver, gallbladder and biliary tree, pancreas, small bowel, large bowel, rectum, and anus. In addition, the Journal of Gastrointestinal Cancer publishes basic and translational scientific information from studies providing insight into the etiology and progression of cancers affecting these organs. New insights are provided from diverse areas of research such as studies exploring pre-neoplastic states, risk factors, epidemiology, genetics, preclinical therapeutics, surgery, radiation therapy, novel medical therapeutics, clinical trials, and outcome studies.In addition to reports of original clinical and experimental studies, the journal also publishes: case reports, state-of-the-art reviews on topics of immediate interest or importance; invited articles analyzing particular areas of pancreatic research and knowledge; perspectives in which critical evaluation and conflicting opinions about current topics may be expressed; meeting highlights that summarize important points presented at recent meetings; abstracts of symposia and conferences; book reviews; hypotheses; Letters to the Editors; and other items of special interest, including:Complex Cases in GI Oncology: This is a new initiative to provide a forum to review and discuss the history and management of complex and involved gastrointestinal oncology cases. The format will be similar to a teaching case conference where a case vignette is presented and is followed by a series of questions and discussion points. A brief reference list supporting the points made in discussion would be expected.
