Abstract excerpt
We analyzed 135 patients (including 27 EGFR-mutant and 29 EGFR-wild) with T1-3N0M0 non-squamous NSCLC treated by PBT. Considering the 3-year cumulative incidence, the EGFR-mutant group showed a significantly lower infield failure rate (9% vs 27%, p = 0.02) and higher out-of-field failure rate (67% vs 40%, p = 0.02) than the EGFR-wild group.
