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.
