Long-Term Outcome in Gastric Cancer Patients with Different Body Composition Score Assessed via Computed Tomography

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.

113 Background: Laparoscopic gastrectomy has been a common tool for gastric cancer patients in eastern Asian countries. A large-scale prospective study with a sample size sufficient to investigate the benefit of laparoscopy-assisted distal gastrectomy (LADG) has never been reported. We conducted a multi-center phase II trial (JCOG0703) to evaluate the safety of LADG with nodal dissection for clinical stage I gastric cancer patients. A short-term outcome including postoperative complications of LADG as a result of this study was already reported and a following multi-center phase III trials (JCOG0912) to confirm the non-inferiority of LADG compared with open gastrectomy in terms of overall survival (OS) was already started. Long-term outcomes as the secondary endpoints of this study are reported here after 5-year follow up period. Methods: The subjects of this study comprised patients with clinical stage I gastric cancer that were able to undergo a distal gastrectomy. LADG with D1 plus suprapancreatic lymph node dissection was performed by credentialed gastric surgeons who experienced >=30 LADG and >=30 open gasterctomy. The primary endpoint was the proportion of patients who developed either anastomotic leakage or a pancreatic fistula. The secondary endpoints included surgical morbidity, short-term clinical outcome, OS, and relapse free survival (RFS). Results: Between November 2007 and September 2008, 176 eligible patients were enrolled. 140/23/9/4 patients had pStage IA/IB/II/IIIA disease respectively. No patients had recurrence. 3 patients died without recurrence. 5-year OS was 98.2% (95%CI, 94.7% to 99.4%). 5-year RFS was 98.2% (95%CI, 94.4% to 99.4%). Conclusions: The long-term outcome of LADG for Stage I gastric cancer patients seem comparable to those of open procedures. However, this result should be confirmed by a randomized control trial. We have just finished an accrual of 921 patients for a multi-center phase III trial (JCOG0912) to confirm the non-inferiority of LADG compared with open gastrectomy in terms of OS.
