RESUMEN
BACKGROUND/AIM: The purpose of this study was to examine the impact of clinicopathological prognostic factors on tumor resectability, perioperative complications, and 5-year survival rates in patients with gastric cancer treated surgically. PATIENTS AND METHODS: A cohort of 834 patients operated on for gastric cancer between 2007 and 2016 was analyzed. RESULTS: Patients over 70 years of age manifested a significantly higher rate of overall complications, systemic complications, surgical complications, perioperative mortality, and a worse 5-year survival. The diffuse type according to the Lauren classification was an independent prognostic factor for perioperative mortality. TNM stage significantly influenced resectability and 5-year survival rates. Furthermore, the presence of distant metastases (M1 stage) significantly increased the rates of overall complications, systemic complications, and perioperative mortality. CONCLUSION: Although TNM stage was the most important prognostic factor for resectability, perioperative complications and 5-year survival, other clinicopathological prognostic factors, such as age, and Lauren type also significantly affected treatment outcomes in gastric cancer surgery.

BACKGROUND: The aim of this study was the analysis of the influence of prognostic factors on short- and long-term outcomes of gastric cancer resection. PATIENTS AND METHODS: A database of 709 patients who had gastric cancer resection between 2007 and 2015 was compiled. RESULTS: Total gastrectomy (TG) and subtotal proximal gastrectomy (SPG) significantly increased the risk of overall complications (p=0.0015 and 0.0173, respectively) and surgical complications (p=0.0141 and 0.0035, respectively). Moreover the resection of an additional organ was an independent prognostic factor of overall complications (p<0.0001), systemic complications (p=0.0503), surgical complications (p<0.0001) and relaparotomy (p=0.0259). T stage (p<0.0001), N stage (p<0.0001), M stage (p<0.0001) and radical resection (p<0.0001) significantly affected 5-year survival rates. CONCLUSION: Early diagnosis and radical resection was crucial in 5-year survival rates. However, the type of gastrectomy and the resection of an additional organ were the most important factors in short-term outcomes of treatment for such patients.
