Survival
After median follow-up time of 57.5 (95% CI: 52.8–62.2) months in ESO-Shanghai 8 study and 41.1 (95% CI: 36.9–45.2) months in this study, the primary endpoint, the 2-year local control rate was 87.9% (95% CI: 83.3–92.4) in this study, which achieved the hypothesized 2-year local control rate of at least 83%. The 2-year overall survival rate were 69.6% in ESO-Shanghai 8 study and 73.6% in this study, respectively (Local control rate (
