Abstract
The effect of VPI on survival in NSCLC varies greatly with tumor size, with VPI not strongly associated with OS or DFS in tumors smaller than 5 cm, but showing large negative effects on DFS for stage T2b and stage T3 tumors. Using VPI to upstage T1 tumors to a higher T stage is not warranted because it would misrepresent these VPI-T stage subgroup effects.
