Abstract This prospective multicenter non-randomized phase III study aims to evaluate the long-term outcome of sentinel node navigation surgery for early gastric cancer compared with conventional distal or total gastrectomy. Clinically diagnosed primary T1N0M0 gastric cancer patients with a single lesion (≤40 mm) and without previous endoscopic treatment will be enrolled in this study. Sentinel nodes are identified by dye and radioisotope tracers and are subjected to intraoperative rapid pathology. For patients with negative sentinel node metastasis, individualized surgery consisting of limited stomach resection and sentinel node basin dissection is performed, while standard gastrectomy with D2 lymph node dissection is employed for the positive sentinel node patients. A total of 225 patients will be accrued from 13 hospitals that have experience in sentinel node mapping. The primary endpoint is 5-year relapse-free survival. The secondary endpoints are overall survival, sentinel node detection rate, diagnostic accuracy for sentinel node, distribution of sentinel nodes and metastatic sentinel node/non-sentinel node, and postoperative quality of life.

Abstract Background: Few studies on the comparison among robotic, laparoscopic, and open gastrectomy had been reported in gastric cancer . The goal of this study was to evaluate the advantages of robotic-assisted gastrectomy (RAG) by comparing with laparoscopic-assisted gastrectomy(LAG) and open gastrectomy (OG). Methods: 147 gastric cancer patients who underwent gastrectomy were enrolled and retrospectively analyzed between January 2017 and July 2019. Short-term outcomes such as operation time, intraoperative estimated blood loss(EBL),number of retrieved lymph nodes, postoperative recovery, learning curve, and long-term outcome such as overall survival(OS) was compared among RAG, LAG and OG groups. Results: RAG group included 47 patients, 44 in the LAG, and 61 in the OG. Basic information such as gender, age, BMI, ASA degree were similar among three groups, and there were no statistically significances in pathological TNM staging, tumor resection extent, resection margin, methods of reconstruction( P >0.05). The cumulative sum(CUSUM) method showed that learning curve of RAG reached stability after 17 cases . For short-term outcomes, the RAG group had the shortest EBL( P =0.033), the shortest time to first flatus( P <0.001), shortest time to first intake liquid diet ( P =0.004),shortest postoperative hospital stay ( P =0.023)and the largest number of retrieved lymph nodes( P =0.044),the longest operation time( P <0.001), the most expensive treatment cost( P <0.001),however, there were no significant differences in postoperative drainage, postoperative white blood cell(WBC)count and early complications among three group( P >0.05). In addition to long-term outcome, similar OS was observed in three groups. Conclusion: Compared with LAG and OG, RAG has certain advantages in short-term outcomes and is a safe and reliable surgical method. But still need further prospective, multi-center research to confirm this.

Background/Aims. Family history (FHx) has been reported to be a risk factor for gastric cancer (GC). However, the long-term prognosis of GC with FHx remains controversial. We aimed to investigate the clinicopathologic characteristics and long-term outcomes of GC according to the presence or absence of GC FHx. Methods. This study was conducted on asymptomatic healthy individuals who underwent upper gastrointestinal endoscopy for the purpose of GC screening. Patients who were diagnosed with GC between October 2003 and December 2013 at Seoul National University Hospital Healthcare System Gangnam Center were identified. Demographic and clinicopathologic characteristics were compared between the groups with and without FHx of GC. Overall survival (OS) and recurrence-free survival (RFS) were assessed as primary outcomes. Results. There were no significant differences in tumor characteristics according to FHx of GC. However, preexisting adenoma was more frequent in patients with FHx than in those without FHx (14.5% vs. 6.3%, p = 0.035 ). The proportion of patients with microsatellite instability (MSI) was also higher in groups with FHx of GC (43.2% vs. 13.2%, p = 0.006 ). Helicobacter pylori infection rates of patients with FHx of GC tended to be higher although not significant (70.5% vs. 61.3%, p = 0.188 ). However, OS and RFS at 5 years of the GC patients with FHx were not significantly different from those of patients without FHx. Conclusion. Preexisting adenoma and GC with MSI are more common in patients with FHx of GC than in those without. There were no significant differences in the survival rate according to FHx.
