Is Complete Resection has a Better Survival in Remnant Gastric Cancer and What Are the Prognositic Factors Affecting These Results

The aim of this study is to investigate the postoperative short- and long-term results of patients operated for remnant gastric cancer and the factors affecting these results. Between 2005 and 2016, 1552 patients were operated for gastric cancer in our clinic. Forty two of these patients were operated for remnant gastric cancer. Forty-one patients was included in this study. The intervals between these two surgeries were included in the survival analysis; it was observed that the length of the intermediate time in both benign and malignant patients (due to the development time of malignancy) extended overall survival and that was statistically significant (p = 0.006 for benign, and p < 0.0001 for malignant). The median survival of resectable patients was 33.5 months, and when we looked at survival analysis, it was observed that the survival was significantly higher than the patients who could not be resected (p < 0.0001). Also survival analysis in patients with resectable disease, it was seen that patients who underwent R0 (microscopically margin-negative resection) resection had a better survival rate compared to patients who underwent R1 resection. According to the results of our study, surgical treatment is effective and provides long-term survival in patients with operable remnant gastric cancer. Low T stage of the disease and R0 resection are the most important parameters affecting survival. As the time between the first gastrectomy and the development of remnant gastric cancer shortens, the prognosis worsens. Performing additional organ resection does not increase mortality and morbidity, and if necessary, additional organ resection should not be avoided to perform R0 resection.
