Abstract
BACKGROUND: This study explores the 3-year survival outcomes and associated influencing factors in patients with primary gastric cancer treated via laparoscopic surgery, providing meaningful guidance for clinical management. AIM: To evaluate and analyze the 3-year survival outcomes and associated risk factors in patients with primary gastric cancer who underwent laparoscopic surgery. METHODS: A total of 100 patients with primary gastric cancer who underwent laparoscopic surgery at our hospital between January 2019 and December 2021 were enrolled. These patients were monitored for 3 years, and their survival statuses were recorded. Patients were categorized into survival and non-survival groups based on their outcomes. Data on sex, age, American Society of Anesthesiologists classification, tumor size, depth of invasion, postoperative adjuvant radio-chemotherapy, postoperative carcinoembryonic antigen (CEA) levels, and other clinical parameters were collected and contrasted across groups to identify factors impacting 3-year survival. RESULTS: After a 3-year follow-up, the survival rate was 73.00% (73 of 100 patients). No significant differences were observed in sex, tumor location, alcohol consumption, smoking status, tumor differentiation, histological type, intraoperative blood loss, or surgical outcomes between patients with varying prognoses (P > 0.05). However, notable disparities were found in age, American Society of Anesthesiologists classification, tumor-node-metastasis (TNM) stage, tumor size, depth of invasion, lymph node metastasis, lymph node dissection, postoperative adjuvant radio-chemotherapy, postoperative CEA levels, surgical duration, extent of gastric resection, and postoperative complications (P < 0.05). Multivariate logistic regression analysis identified age, TNM stage, tumor size, depth of invasion, lymph node metastasis, lymph node dissection, postoperative adjuvant radio-chemotherapy, postoperative CEA levels, surgical duration, extent of gastric resection, and postoperative complications as independent predictors of 3-year survival in patients with primary gastric cancer following laparoscopic surgery (P < 0.05). CONCLUSION: The 3-year survival outcome for patients undergoing laparoscopic surgery for primary gastric cancer was 73.00%. Key determinants of survival included age, TNM stage, tumor size, depth of invasion, and lymph node metastasis. This analysis of 3-year survival and its influencing factors offers novel perspectives for optimizing clinical interventions in patients with primary gastric cancer treated via laparoscopic surgery.
