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

Figure 2 Kaplan-Meier survival analysis comparing 1-year survival rates between ultrasound-guided and conventional surgical approaches in early gastric cancer patients. The blue line represents the observation group (ultrasound-guided precise localization technology, n = 52), and the red line represents the control group (conventional surgical treatment, n = 48). The analysis revealed superior survival outcomes in the ultrasound-guided group, with a 1-year survival rate of 96.2% compared with 91.7% in the control group, although the difference did not reach statistical significance (P > 0.05, log-rank test).
