Abstract

PURPOSE
Remnant gastric cancer is defined as a malignant tumor developing on the remnant side of stomach after partial gastrectomy. The purpose of this study is to evaluate the clinical characteristics and prognosis of remnant gastric cancer according to the cause and the reconstruction method of previous surgery.
METHODS
Between January 2007 and February 2016, we analyzed 39 patients with their medical records who were diagnosed as remnant gastric cancer and underwent gastrectomy at Inje University Busan Paik Hospital.
RESULTS
In the comparison of malignant disease (MD) and benign diseases (BD) group, the Billroth I:Billroth II ratio was 52.2% and 12.5%. The time interval from the previous operation to the diagnosis of remnant gastric cancer (RGC) was shorter in the MD group than in the BD group (6.6±6.04 vs. 34.7±10.12 years). Comparing B1 and B2 group, the proportion of patients previously undergone surgery due to MD was 85.7% and 44%. The time interval was higher in the B1 group than in the B2 group (8.0±8.78 vs. 23.8±16.48 years). Analyzing prognostic factors of survival, age and the presence of symptoms at the time of RGC diagnosis, and curability of surgery had a significant effect on the survival of the patients (P=0.032, hazard ratio [HR]=5.241, 95% confidence interval [CI], 1.158-23.723; P=0.005, HR=5.086, 95% CI, 1.642-15.750; P=0.034, HR=3.165, 95% CI, 1.088-9.208).
CONCLUSION
Patients who underwent partial gastrectomy for benign or MD require regular endoscopic follow-up and appropriate surgical approach is essential for the treatment of RGC.
