Application of ultrasound-guided localization technology in early gastric cancer surgery and prognostic analysis

Figure 4 Logistic regression analysis of recurrence risk. Through logistic regression analysis of factors associated with cancer recurrence, we found that precise ultrasound-guided localization significantly reduced the risk of recurrence [odds ratio (OR) = 0.43, 95% confidence interval (CI): 0.26-0.72; P = 0.001]. Other significant factors included lymph node metastasis (OR = 3.28, 95%CI: 2.14-5.02, P < 0.001), tumor depth (OR = 2.17, 95%CI: 1.45-3.25, P < 0.001), number of lymph nodes dissected (OR = 0.65, 95%CI: 0.48-0.89, P = 0.007), tumor size (OR = 1.85, 95%CI: 1.23-2.79, P = 0.003), age > 65 years (OR = 1.47, 95%CI: 1.01-2.13, P = 0.042), and positive surgical margins (OR = 2.76, 95%CI: 1.84-4.14, P < 0.001). OR: Odds ratio.
